ACTION: Proposed rule; withdrawal and reproposal; request for comments. AGENCY: On November 27, 2020, we, NMFS, published in the Federal Register a proposal to designate 17 island units of critical habitat in the Pacific Islands Region for 7 Indo-Pacific coral species listed under the Endangered Species Act (ESA). Based on public comments and new information regarding the interpretation of the records of the listed corals and application to critical habitat, a substantial revision of the proposed rule is warranted. Accordingly, we are withdrawing the 2020 proposed rule and publishing this new proposed rule. We propose to designate critical habitat for five of the seven coral species that were addressed in the 2020 proposed rule: Acropora globiceps, Acropora retusa, Acropora speciosa, Euphyllia paradivisa, and Isopora crateriformis. Proposed critical habitat includes 16 island units encompassing approximately 251 square kilometers ((km2); 97 square miles (mi2)) of marine habitat. Several areas are ineligible for critical habitat because of final Department of Defense Integrated Natural Resource Management Plans that we have determined will benefit the listed corals. We have considered economic, national security, and other relevant impacts of the proposed designations, but are not proposing to exclude any areas from the critical habitat designations due to anticipated impacts. DATES: Comments on this proposal must be received by February 28, 2024. Public hearings: Public hearings on this proposed rule will be held during the public comment period at dates, times and locations to be announced in a forthcoming Federal Register Notice.

SUPPLEMENTARY INFORMATION: Background We listed 20 reef coral species as threatened under the ESA on September 10, 2014 (79 FR 53851), 15 of which occur in the Indo-Pacific. The remaining five species occur in the Caribbean. On November 27, 2020, we proposed critical habitat for the seven listed IndoPacific species that were then considered to occur within U.S. jurisdiction (85 FR 76262) and the five listed Caribbean species (85 FR 76302). All 20 of these listed coral species have undergone some level of population decline and are susceptible to multiple threats, including ocean warming, diseases, ocean acidification, ecological effects of fishing, and land-based sources of pollution. We determined that these species are likely to become endangered throughout their ranges within the foreseeable future as a result of a combination of threats, the most severe of which are related to climate change. PO 00000 Frm 00002 Fmt 4701 Sfmt 4702 On November 27, 2020, NMFS proposed to designate critical habitat for the seven listed Indo-Pacific corals that were then considered to occur within U.S. jurisdiction (Acropora globiceps, Acropora jacquelineae, Acropora retusa, Acropora speciosa, Euphyllia paradivisa, Isopora crateriformis, and Seriatopora aculeata) and opened a public comment period (85 FR 76262). In response to multiple requests from the public, the initial 60-day public comment period was extended three times, with the last extension ending on May 26, 2021. Two virtual public hearings were held in January 2021. Approximately 80 public comments were received on the proposed rule. The coral critical habitat proposed for designation in 2020 (the ‘‘2020 proposed rule’’) consisted of substrate and water column habitat characteristics essential for the reproduction, recruitment, growth, and maturation of the seven listed coral species. A total of 17 areas or ‘‘units’’ were proposed to be designated as critical habitat, including 4 units in American Samoa (Tutuila and Offshore Banks, Ofu-Olosega, Ta’u, Rose Atoll), 1 unit in Guam, 7 units in the Commonwealth of the Northern Mariana Islands (CNMI; Rota, Aguijan, Tinian, Saipan, Anatahan, Pagan, Maug), and 5 units in the Pacific Remote Islands Areas (PRIA; Howland, Palmyra Atoll, Kingman Reef, Johnston Atoll, Jarvis). Based on the best available information at that time, between 1 and 6 listed coral species were thought to occur within each of these 17 units. Several other areas were also found to be either ineligible for designation as critical habitat, or were proposed to be excluded from the designation due to national security impacts. These areas included the following: A complex of overlapping Navy Surface Danger Zones off of Ritidian Point in Guam, other parts of Guam, parts of Tinian in CNMI, a group of six Navy anchorage berths on Garapan Bank in Saipan in CNMI, all of Farallon de Medinilla in CNMI, and all of Wake Atoll in PRIA. The ESA defines critical habitat under section 3(5)(A) as the (1) specific areas within the geographical area occupied by the species at the time it is listed, on which are found those physical or biological features essential to the conservation of the species and which may require special management considerations or protection; and (2) specific areas outside the geographical area occupied by the species at the time it is listed, upon a determination by the Secretary of Commerce (Secretary) that such areas are essential for the conservation of the species (16 U.S.C. 1532(5)(A)). Conservation is defined in E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules section 3(3) of the ESA as to use, and the use of, all methods and procedures which are necessary to bring any endangered species or threatened species to the point at which the measures provided pursuant to this Act are no longer necessary (16 U.S.C. 1532(3)). Section 3(5)(C) of the ESA provides that, except in those circumstances determined by the Secretary, critical habitat shall not include the entire geographical area which can be occupied by the threatened or endangered species. ESA implementing regulations provide that critical habitat shall not be designated within foreign countries or in other areas outside U.S. jurisdiction (50 CFR 424.12(g)). Section 4(a)(3)(B)(i) of the ESA prohibits designating as critical habitat any lands or other geographical areas owned or controlled by the Department of Defense (DOD) or designated for its use, that are subject to an Integrated Natural Resources Management Plan (INRMP) prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if the Secretary determines in writing that such plan provides a benefit to the species for which critical habitat is designated. Section 4(b)(2) of the ESA requires us to designate critical habitat for threatened and endangered species on the basis of the best scientific data available and after taking into consideration the economic, national security, and any other relevant impact, of specifying any particular area as critical habitat. Pursuant to this section, the Secretary may exclude any area from critical habitat if she determines the benefits of such exclusion outweigh the benefits of specifying such area as part of the critical habitat. However, the Secretary cannot exclude areas if failure to designate them as critical habitat will result in the extinction of the species (16 U.S.C. 1533(b)(2)). Once critical habitat is designated, section 7(a)(2) of the ESA requires Federal agencies to ensure that actions they fund, authorize, or carry out are not likely to destroy or adversely modify that habitat (16 U.S.C. 1536(a)(2)). This requirement is in addition to the section 7(a)(2) requirement that Federal agencies ensure their actions are not likely to jeopardize the continued existence of ESA-listed species. Specifying the geographic location of critical habitat also facilitates implementation of section 7(a)(1) of the ESA by identifying areas where Federal agencies can focus their conservation programs and use their authorities to further the purposes of the ESA. Critical habitat requirements do not apply to citizens engaged in actions on private VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 land that do not involve a Federal agency. The requirements of section 7(a)(2) to not destroy or adversely modify critical habitat apply only to Federal agencies and do not apply to non-Federal entities on non-Federal land or within non-Federal waters in the absence of a Federal nexus (e.g. Federal funding, Federal permit). However, designating critical habitat can help focus the efforts of other conservation partners (e.g., state and local governments, individuals, and nongovernmental organizations). On July 5, 2022, the U.S. District Court for the Northern District of California issued an order vacating the ESA section 4 implementing regulations that were revised or added to 50 CFR part 424 in 2019 (‘‘2019 regulations,’’ see 84 FR 45020, August 27, 2019) without making a finding on the merits. On September 21, 2022, the U.S. Court of Appeals for the Ninth Circuit granted a temporary stay of the district court’s July 5 order (Wash. Cattlemen’s Ass’n, No. 22–70194, 2022 WL 4393033). On November 14, 2022, the Northern District of California issued an order granting the government’s request for voluntary remand without vacating the 2019 regulations. The District Court issued a slightly amended order two days later on November 16, 2022 (Ctr. for Biological Diversity v. Haaland, No. 19–cv–05206–JST, 2022 WL 19975245). As a result, the 2019 regulations remain in effect, and we are applying the 2019 regulations here. We also note that, on June 22, 2023, our agency in coordination with the Department of Interior jointly published proposed revisions to the ESA section 4 regulations (88 FR 40764). For purposes of this determination and in an abundance of caution, we considered whether the analysis or its conclusions would be any different under the current, pre-2019, and recently proposed regulations. We have determined that while the analysis differs in some ways, the conclusions presented here would not be any different. We will consider any changes to the section 4 regulations, as appropriate, should they be finalized and become effective prior to completion of a final critical habitat determination. In this rulemaking, the terms ‘‘occupied area,’’ ‘‘specific area,’’ and ‘‘critical habitat unit’’ each have distinct meanings. The terms ‘‘occupied area’’ and ‘‘specific area’’ are species-specific, whereas the term ‘‘critical habitat unit’’ is not species-specific. The term ‘‘occupied area’’ is consistent with the definition of the ‘‘geographical area occupied by the species’’ in 50 CFR PO 00000 Frm 00003 Fmt 4701 Sfmt 4702 83645 424.02 and refers to the area that may generally be delineated around species’ occurrences at the time of listing, as determined by the Secretary—i.e., range. Within each occupied area, ‘‘specific areas’’ are the areas containing the essential feature of critical habitat for the species. We use the term ‘‘critical habitat unit’’ to refer to the cumulative specific areas for one or more species around the 16 islands proposed for designation. Critical habitat units are named according to the particular island or offshore bank around, or on which, the coral habitat is located. For example, overlapping occupied areas for five listed coral species occur around Tutuila Island and its offshore banks, which is thus named the Tutuila and Offshore Banks Unit of coral critical habitat. Rationale for Withdrawing 2020 Proposed Rule We evaluated the comments and information received during the public comment period and at the public hearings that were held for the 2020 proposed rule, as well as other new information that has become available, as described in the Critical Habitat Information Report for this proposed rule (NMFS, 2023) and its appendices. Based on our consideration of the comments and information, a substantial revision of the 2020 proposed rule is needed for three main reasons: 1. The initial methodology used to compile existing records of listed coral species in U.S. waters was not exhaustive, resulting in the inadvertent exclusion of some islands within the occupied area for some listed species that should have been included as occupied areas. 2. The initial methodology used to determine which U.S. islands were within the occupied area for each listed coral species at the time of listing (2014) was too simplistic, resulting in the inadvertent inclusion of some islands in the occupied area for some listed species that should not have been included. 3. The initial methodology used to determine the depth range of each listed species on each island within its occupied area used incorrect assumptions, resulting in inaccurate depth ranges for some species in some locations (i.e., some depth ranges were larger than they should have been). With regard to the compilation of records of listed coral species in U.S. waters, in developing the 2020 proposed rule, we relied on Federal coral reef monitoring programs as the only source of records used for most of the remote E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 83646 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules islands. However, as pointed out in the public comments and also as indicated by new information, other records exist for some islands. Specifically, several sources of photo records and expert data records have been published or shared since the 2020 proposed rule published, and some previously unused historical photo records were found to have been mislabeled with the names of unlisted species. As a result, numerous existing records that were not considered in the 2020 proposed rule, including some that provide the only records of any listed coral species on some islands, were considered in developing this proposed rule. With regard to determining the occupied area within U.S. jurisdiction for each listed coral species for the 2020 proposed rule, we assumed that any expert record of a listed coral species was adequate to conclude that the island was within the occupied area for that species at the time of listing. However, as pointed out in the public comments and also as indicated by new information, for those islands with very few records for a listed coral species, such records may not provide adequate evidence that the island was within the occupied area of the listed species at the time of listing. There are several potential reasons for this, including species misidentifications, old records of species that were no longer present at the time of listing, and the likelihood that a single record of a colony of a listed species represents a vagrant individual. For example, only a single colony of the listed coral Acropora jacquelineae has ever been recorded in U.S. waters on Tutuila, an island that has been frequently surveyed by coral experts since that single colony was recorded in 2008, and that record was used as the basis for including A. jacquelineae in the 2020 proposed rule. However, as indicated in the public comments and by new information, that record likely represents a vagrant individual of A. jacquelineae, and thus Tutuila should not be considered as being occupied by the species at the time of listing. Therefore, the mere existence of an expert record of a listed coral from an island is not necessarily adequate to support a conclusion that the area was within the occupied area of the species at the time of listing. With regard to the species’ depth ranges applied in the 2020 proposed rule, we assumed that the depth range of a listed coral species shown by the records from an extensively surveyed island was similarly representative of that species’ depth range on other islands. For example, since the records of A. globiceps from Tutuila showed a VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 depth range of 0–20 m on that island, we assumed that the species’ depth range was 0–20 m in other locations where we lacked depth distribution data, including islands within (e.g., Rose Atoll) and outside (e.g., Guam) the Samoan Archipelago. However, as indicated in the public comments and by new information, the depth range of a listed coral species can vary from island to island, especially between archipelagos. For example, surveys that became available or were conducted since the 2020 proposed rule between 10 and 20 m on both Tutuila and Guam indicate that A. globiceps is commonly found to 20 m on Tutuila in the Samoan Islands but only to 12 m on Guam in the Mariana Islands. In order to address these issues with the 2020 proposed rule, a systematic methodology was developed and implemented for compilation, assessment, and interpretation of the records of each listed coral species in order to determine its occupied area within U.S. waters at the time of listing in 2014 (i.e., which islands) as well as the depth range of each species on each of those islands. This new methodology resulted in significant changes to the occupied area (i.e., which islands are included or not), as well as depth ranges of critical habitat for most listed coral species. Ultimately, these changes altered which species are considered to occupy areas within U.S. jurisdiction and the location and boundaries of the areas proposed for designation. Specifically, two species included in the 2020 proposed rule, Acropora jacquelineae and Seriatopora aculeata, are no longer considered to have occupied areas within U.S. jurisdiction at the time of listing, and we cannot designate critical habitat in areas outside U.S. jurisdictions (50 CFR 424.12(g)). In addition, some new areas are being proposed that were not included in the 2020 proposed rule (Alamagan and Uracas in CNMI, French Frigate Shoals in Hawaii). Given these multiple, substantial changes, we concluded it was necessary to withdraw the 2020 proposed rule and publish this proposed rule to provide the public an opportunity to comment on the new methodology and the different areas being proposed as critical habitat. New Methodology for Determining Occupied Areas and Depth Ranges The determinations of the occupied areas and depth ranges that inform critical habitat are based on the records of each listed coral species within U.S. waters. However, using the records for critical habitat requires overcoming three major challenges: (1) Finding all PO 00000 Frm 00004 Fmt 4701 Sfmt 4702 the records (compilation); (2) accounting for the high variability in the quality, quantity, age, species identification uncertainty, survey effort, and other factors associated with the records (assessment); and (3) interpreting the records to determine which islands are within the occupied area for each listed species and thus should be included in critical habitat (application). In order to address these challenges and ensure that coral critical habitat is based on the best available information, we conducted exhaustive searches to compile all the available records for each listed coral species around each island within U.S. Pacific Islands jurisdictions, and developed a consistent and transparent methodology for assessing and applying the records. The results are provided in appendix A of the Information Report (NMFS, 2023), hereafter referred to as the Records Document, and provide the foundation for this new proposed rule. The compilation, assessment, and application of the records are summarized from the Records Document below. Compilation of Records We compiled the available records for each listed coral species around each island within U.S. Pacific Islands waters via the following steps: (1) Reviewed all relevant NOAA Fisheries files, such as those used for the final coral listing rule and 2020 proposed critical habitat; (2) gathered records from government agencies that have conducted coral reef monitoring within these areas; (3) gathered records from other sources such as research projects, site surveys, area inventories, etc.; (4) conducted an exhaustive virtual search; and (5) consulted with experts from the Territorial Governments (American Samoa, Guam, CNMI) and the Marine National Monuments (Rose Atoll, Pacific Remote Islands, Marianas Trench) to ensure that no records were overlooked. Some of these records were brought to our attention by the public comments that we received during the public comment period in 2021. The search produced records of seven listed coral species (A. globiceps, A. jacquelineae, A. retusa, A. speciosa, E. paradivisa, I. crateriformis, and S. aculeata) from U.S. Pacific Islands waters (NMFS, 2023, appendix A). This comprehensive compilation process yielded more than twice as many records as were used for the 2020 proposed rule, including historical records that we were unaware of in 2020 as well as new data collected since then. The records were divided into 45 records groups by island and species. E:\FR\FM\30NOP2.SGM 30NOP2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS2 Throughout this proposed rule and in the supporting documents, we refer to high islands (volcanic, e.g., Guam), atolls (e.g., Rose Atoll), stand-alone reefs (e.g., Kingman Reef), shoals (e.g., French Frigate Shoals (FFS)), and pinnacles (e.g., Gardner Pinnacles) as ‘‘islands.’’ The 45 records groups included a total of 24 such islands, 4 of which were in American Samoa (Tutuila and Offshore Banks, Ofu-Olosega, Ta’u, Rose Atoll), 1 in Guam (Guam), 9 in CNMI (Rota, Aguijan, Tinian, Saipan, Farallon de Medinilla (FDM), Alamagan, Pagan, Maug Islands, Uracas), 7 in PRIA (Howland, Baker, Palmyra Atoll, Kingman Reef, Johnston Atoll, Wake Atoll, Jarvis), and 3 in the Northwestern Hawaiian Islands (FFS, Maro Reef, Gardner Pinnacles) in Hawaii, as shown in table 2 of appendix A. We found no records of any listed species in any of the Main Hawaiian Islands (NMFS, 2023, appendix A). Assessment of Records We assessed each of the 45 records groups (i.e., all records of a listed species from an island) in terms of the multiple factors, including (1) quality of records, (2) quantity of records, (3) age of records, (4) species identification uncertainty, and (5) survey effort. We addressed the quality of records by organizing the records into three mutually-exclusive categories: ‘‘photo records,’’ ‘‘expert data records,’’ or ‘‘other records.’’ Because of species identification uncertainty, photo records are ideal, as long as the location and date of the photo are known, and the photo clearly shows colony and branch morphology. However, many records of coral species are in the form of data sheets or species lists, and lack photos. Any such record collected by a recognized Indo-Pacific reef-building coral species expert is considered an expert data record. Records that do not meet the criteria for photo records or expert data records are considered other records (e.g., personal communications). We confirmed all records via direct communication with the experts who took the records, or with experts who were able to vouch for the records. Our determinations of whether the island was within the occupied area for a listed species at the time of listing relied almost entirely upon photo records and expert data records. However, other records provided valuable information for some islands or parts thereof. For example, records that do not meet the criteria for photo or expert data records (i.e., exact dates and locations not available) provide information on depth and habitat distributions (NMFS, 2023, appendix A). VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 Although we did not specify a particular quantity of records necessary to support a determination that a particular island was within the occupied area for a listed species at the time of listing, the more photo records and expert data records we have for a species from an island, the greater the likelihood that the island was within the occupied area for a listed species at the time of listing. Islands with a single photo record or expert data record of a listed species may or may not have been within the occupied area of that species at the time of listing (2014), depending on other factors (NMFS, 2023, appendix A). Older records are not necessarily lower quality, thus age of records was not a consideration for determining the quality of a record. However, the more that a record predates listing, the less relevance it had to our determination of whether the island was within the occupied area for a listed species at the time of listing (NMFS, 2023, appendix A). Species identification uncertainty is substantial for most of the 15 listed Indo-Pacific reef coral species, even for experts. For listed coral species that are consistently distinct from similar species and frequently observed, species identification uncertainty has decreased since listing, as survey effort and expertise have increased. This is the case with A. globiceps and I. crateriformis. In addition, E. paradivisa and S. aculeata are consistently distinct from similar species, although they are very infrequently observed within U.S. waters. For these four listed species, identification uncertainty is relatively low at this point in time for coral species experts based in the U.S. Pacific Islands. In contrast, for listed species that are very similar to other species, the increase in survey effort since listing in 2014 has emphasized the difficulty in distinguishing them. This is the case with A. retusa, especially in the Marianas and PRIA. The combination of high colony morphological variability and low numbers of records from the Marianas (i.e., Guam and CNMI) and PRIA is such that we have low confidence in these records, even though they are expert data records. Even more challenging are those listed species that are very similar to other species but are very infrequently observed, such as A. jacquelineae and A. speciosa. For these three listed species, identification uncertainty is relatively high at this point in time, even for coral species experts who focus on the U.S. Pacific Islands (NMFS, 2023, appendix A). PO 00000 Frm 00005 Fmt 4701 Sfmt 4702 83647 A particular species identification uncertainty problem is the apparent variability in colony morphology of A. retusa and related species between the American Samoa, Guam-CNMI, and PRIA archipelagos. The combination of high colony morphological variability and low numbers of records in GuamCNMI and PRIA is such that we have low confidence in these records, even though they are expert data records. However, in American Samoa, there is apparently lower colony morphological variability and higher numbers of records for A. retusa, thus we have high confidence in these records. Survey effort refers to the amount of expert coral species surveys that have been conducted on an island. Historical survey effort has been highly variable from island to island, potentially influencing the interpretation of the records. However, all islands in this document except FDM in CNMI have been included in the Pacific Islands Fisheries Science Center’s (PIFSC) species-level standardized coral reef monitoring surveys at least one time since listing in 2014, and some islands have also been included in standardized surveys by other agencies. PIFSC’s surveys are quite extensive around each island, including a large number of transects and covering wide depth ranges (appendix A). The Department of the Navy (DON) restricts access to FDM, hence PIFSC does not survey there. However, the Navy periodically conducts species-level coral surveys at FDM by recognized Indo-Pacific reefbuilding coral species experts, thus numerous surveys have been conducted on FDM both around and since the time of listing. All islands have been subject to extensive species-level surveys (i.e., the PIFSC and DON surveys) around or since the time of listing, including within the depth ranges and habitat types of all listed coral species (NMFS, 2023, appendix A). Several other factors were taken into consideration in assessing the records, including taxonomic issues, morphological variability across archipelagos, and habitat preferences. Taxonomic issues include confusion of A. globiceps with A. humilis, and the name change from Acropora crateriformis to Isopora crateriformis, both of which affected how we treated historical records. Finally, some types of coral reef habitats are surveyed more than others, mainly because of accessibility and safety. Of the surveys that produced the records in this document, the majority took place on forereefs (AKA reef slopes) between about 5 and 20 m of depth, and some surveys included reef slopes of 20–30 m E:\FR\FM\30NOP2.SGM 30NOP2 83648 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules depth. Fewer surveys were done in backreef habitats, such as pools, lagoons, and reef flats, raising the possibility that the records may not be representative of species’ distributions across habitats. However, for some of the more frequently surveyed islands, habitat-specific information is available, as noted in the species-island sections (NMFS, 2023, appendix A). Based on the assessment factors, we developed a 10-category system for rating the level of evidence provided by each records group (i.e., all records of a listed species from an island) that the island was within the occupied area for the listed species at the time of listing in 2014, from the least to the most evidence (table 1). Then we interpreted the rating results of each records group to determine whether the island was within the occupied area for the listed species at the time of listing, and thus should be included in critical habitat. For islands within the occupied area of a listed species, we also used the records to determine the depth range of that species on the island.

We considered record groups with ratings of 1–3 as providing inadequate evidence that the island was within the occupied area for the listed species at the time of listing. Eighteen of the 45 records groups were rated as 1–3 (table 1). The rationales for why these records groups provide inadequate evidence for the species being within the occupied area at the time of listing are summarized below from the Records Document (NMFS, 2023, appendix A). One A. jacquelineae records group was rated as 1 (Tutuila), a species with high species identification uncertainty even for trained experts. This record consists of photos of a single colony of A. jacquelineae on Tutuila taken in 2008. Since then, hundreds of expert surveys have been conducted on Tutuila VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 2 records groups: A. globiceps from Alamagan and Uracas. 2 records groups: A. retusa from Wake Atoll; and A. speciosa from Tutuila. 7 records groups: A. globiceps from Ta’u, Rose Atoll, FDM, Palmyra Atoll, Johnston Atoll, and FFS; and E. paradivisa from Tutuila. 1 records group: A. retusa from Ofu-Olosega. 6 records groups: A. globiceps from Ofu-Olosega, Aguijan, Pagan, Maug Islands, and Wake Atoll; and I. crateriformis from Ta’u. 2 records groups: A. retusa from Tutuila and Rose Atoll. 7 records groups: A. globiceps from Tutuila, Guam, Rota, Tinian, and Saipan; and I. crateriformis from Tutuila and Ofu-Olosega. within the habitat and depth range of the species, including at the location of the original record, but no other records have been documented. The regulatory definition of an occupied area does not include habitats used solely by vagrant individuals (i.e., waifs). Waifs are a single individual or small group of individuals found outside of its normal range, presumably advected by unusual currents or weather conditions (Johnson et al., 2000), which are common among reef corals (Turak and DeVantier, 2019). Based on the fact that no other colonies of A. jacquelineae have been observed before or since 2008 on Tutuila despite extensive expert surveys, there is considerable likelihood that the single observed colony of A. jacquelineae on Tutuila was a waif colony. Since occupied areas do not include habitats used solely by vagrant individuals (i.e., waifs), this record provides inadequate evidence that Tutuila was within the occupied area of A. jacquelineae at the PO 00000 Frm 00006 Fmt 4701 Sfmt 4702 time of listing in 2014 (NMFS, 2023, appendix A). Seven A. retusa records groups were rated as 1 (Ta’u, Guam, Rota, Tinian, Howland, Kingman Reef, Johnston Atoll), a species with high species identification uncertainty even for trained experts. All seven records groups consist of one or two records collected at least several years before listing (2004—2010). Five of the records groups each consist of one or two photo records that all appear to be of closelyrelated but undescribed species. The other two records groups (Ta’u, Rota) each consist of a single expert data record but because of species identification uncertainty and lack of photos, identifications could not be confirmed. Because these records groups each consist of only one or two ambiguous records collected at least several years before listing, and expert surveys of all seven islands since listing have not recorded any A. retusa E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules colonies, these records groups provide inadequate evidence that any of the seven islands were within the occupied area of A. retusa at the time of listing in 2014 (NMFS, 2023, appendix A). Two A. speciosa records groups were rated as 1 (Guam, Kingman Reef), a species with high species identification uncertainty even for trained experts. The Guam records group consists of several photos of a single colony in Apra Harbor of Guam taken in 2010. Definitive species identification requires examination of a skeletal sample, but no sample was taken. Many subsequent expert dives and surveys were conducted in the area in the following years, but neither the original colony nor any other colonies resembling A. speciosa were recorded. The Kingman Reef records group consists of a single expert data record collected between 2004 and 2006 with no photos or skeletal sample. Because these records groups each consist of only a single ambiguous colony recorded at least several years before listing, and expert surveys of both islands since listing have not recorded any A. speciosa colonies, these records groups provide inadequate evidence that either island was within the occupied area of A. speciosa at the time of listing in 2014 (NMFS, 2023, appendix A). Five A. globiceps records were groups rated as 2 (Howland, Baker, Kingman Reef, Maro Reef, Gardner Pinnacles), a species with low species identification uncertainty for trained experts. All five records groups consist of one or two photo records collected at least several years before listing (2000–2006). The three records groups from PRIA (Howland, Baker, Kingman Reef) each consist of one or two photo records taken between 2004 and 2006 and identified by an expert at that time but that are clearly not A. globiceps, and thus provide no evidence that these three islands were within the occupied area of A. globiceps at the time of listing in 2014. The two records groups from NWHI (Maro Reef, Gardner Pinnacles) are a photo of a single colony from 2004 (Maro Reef) and photos of a group of colonies in close proximity from 2000 (Gardner Pinnacles). Because these records groups each consist of only a single colony or group of colonies (i.e., likely clones) collected many years before listing, multiple expert surveys conducted at Maro Reef and Gardner Pinnacles through 2008 did not record any A. globiceps colonies, and an expert survey of both islands since listing did not record any A. globiceps colonies, these records groups provide inadequate evidence that either island was within the occupied area of A. globiceps at the VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 time of listing in 2014 (NMFS, 2023, appendix A). Two S. aculeata records groups were rated as 2 (Guam, Saipan), a species with low species identification uncertainty for trained experts. The Guam records group consists of three photo records (two from the 1970s and one from 2010), while the Saipan records group consists of an expert data record of a cluster of colonies in close proximity (i.e., likely clones) from 2011. Since 2010 and 2011, hundreds of expert surveys have been conducted on Guam and Saipan within the habitat and depth range of S. aculeata, but no additional records have been documented. Since the most recent of these records were collected in 2010 (Guam) and 2011 (Saipan), there have been sharp declines in coral cover throughout Guam and Saipan, especially of branching corals such as S. aculeata, due to a multitude of disturbances. There are several reasons why these records groups provide inadequate evidence that either island was within the occupied area of S. aculeata at the time the species was listed in 2014. First, each records group consists of only a few records collected between the 1980s and 2010. Second, hundreds of expert surveys have been conducted on Guam and Saipan since listing in 2014 but did not record any additional S. aculeata colonies. Third, there have been sharp declines in the coral cover of branching corals such as S. aculeata on Guam and Saipan that started at least several years before listing in 2014 (NMFS, 2023, appendix A). One A. retusa records group was rated as 3 (Jarvis), a species with high species identification uncertainty even for trained experts. This records group consists of a single photo taken in 2018 although the photo does not clearly show branch and colony morphology. Like the other A. retusa photo records from PRIA, the colony could only be identified as possible A. retusa colonies because of a combination of species identification uncertainty and taxonomic ambiguity. Because A. retusa has high species identification uncertainty especially in PRIA, the records group consists of only one poor quality and ambiguous photo record, and post-listing standardized monitoring surveys in 2015 and 2018 at Jarvis did not detect any A. retusa colonies, this records group does not provide adequate evidence that Jarvis was within the occupied area of A. retusa at the time of listing in 2014 (NMFS, 2023, appendix A). We considered record groups with ratings of 4–10 to provide adequate PO 00000 Frm 00007 Fmt 4701 Sfmt 4702 83649 evidence that the island was within the occupied area for the listed species at the time of listing. Twenty-seven of the 45 records groups were rated as 4–10 (table 1), and the rationales for why these records groups provide adequate evidence for the species being within the occupied area at the time of listing are summarized below from the Records Document (NMFS, 2023, appendix A). Two A. globiceps records groups were rated as 4 (Alamagan, Uracas), a species with low species identification uncertainty for trained experts. These records groups consist of one (Alamagan) and two (Uracas) photo records, all taken in 2017. No expert surveys have been conducted on either island since then, except PIFSC’s standardized monitoring survey in 2022, details for which are not yet available. Because A. globiceps has low species identification uncertainty, and these records consist of photo records taken in 2017, these records groups provide adequate evidence that the two islands were within the occupied area of A. globiceps at the time of listing in 2014 (NMFS, 2023, appendix A). Two records groups were rated as 5, A. retusa from Wake Atoll, and A. speciosa from Tutuila. Both species have high species identification uncertainty even for trained experts. The A. retusa/Wake records group consists of many photo and expert data records since listing in 2014, although standardized monitoring surveys have not detected the species on Wake. The A. speciosa/Tutuila records group consists of several photo and expert data records before and after listing in 2014, including two from 2016 that were confirmed with skeletal samples, and one record from a standardized monitoring survey that was not confirmed with a skeletal sample. Although both species have high species identification uncertainty even for trained experts, the A. retusa/Wake records group consists of many photo and expert data records since listing, and the A. speciosa/Tutuila records group includes multiple post-listing records that were confirmed with skeletal samples. Thus the records groups provide adequate evidence that Wake Atoll was within the occupied area of A. retusa, and that Tutuila was within the occupied area of A. speciosa, at the time of listing in 2014 (NMFS, 2023, appendix A). Seven records groups were rated as 6, six for A. globiceps (Ta’u, Rose Atoll, FDM, Palmyra Atoll, Johnston Atoll, FFS), and one for E. paradivisa from Tutuila. Both species have low species identification uncertainty for trained experts. Each of the seven records E:\FR\FM\30NOP2.SGM 30NOP2 83650 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules groups include several records collected before and after listing in 2014. Because both species have low species identification uncertainty, multiple records are available for all seven islands, and records were collected after listing, these records groups provide adequate evidence that the six islands were within the occupied area of A. globiceps, and that Tutuila was within the occupied area of E. paradivisa, at the time of listing in 2014 (NMFS, 2023, appendix A). One A. retusa records group was rated as 7 (Ofu-Olosega), a species with high species identification uncertainty even for trained experts. This records group consists of several records collected before and after listing in 2014. Although A. retusa generally has high species identification uncertainty, colonies of the species have a typical and distinct appearance in American Samoa. Because multiple records are available, some of which were collected after listing, this records group provides adequate evidence that Ofu-Olosega was within the occupied area of A. retusa at the time of listing in 2014 (NMFS, 2023, appendix A). Six records groups were rated as 8, five for A. globiceps (Ofu-Olosega, Aguihan, Pagan, Maug Islands, Wake Atoll), and one for I. crateriformis from Ta’u. Both species have low species identification uncertainty for trained experts. Each of the six records groups consist of many records collected after listing in 2014. Because both species have low species identification uncertainty, and many records are available for all six islands since listing, these records groups provide adequate evidence that the five islands were within the occupied area of A. globiceps, and that Ta’u was within the occupied area of I. crateriformis, at the time of listing in 2014 (NMFS, 2023., appendix A). Two A. retusa records groups were rated as 9 (Tutuila, Rose Atoll), a species with high species identification uncertainty even for trained experts. These records groups each consist of dozens of records collected after listing in 2014. Although A. retusa generally has high species identification uncertainty, colonies of the species have a typical and distinct appearance in American Samoa. Because dozens of records are available from after listing for both islands, these records groups provide adequate evidence that Tutuila and Rose Atoll were within the occupied area of A. retusa at the time of listing in 2014 (NMFS, 2023, appendix A). Seven records groups were rated as 10, five for A. globiceps (Tutuila, Guam, Rota, Tinian, Saipan), and two for I. crateriformis (Tutuila, Ofu-Olosega). Both species have low species identification uncertainty for trained experts. Each of the seven records groups consist of dozens to hundreds of records collected after listing in 2014. Because both species have low species identification uncertainty, and many records are available for all seven islands since listing, these records groups provide adequate evidence that the five islands were within the occupied area of A. globiceps, and that Tutuila and Ofu-Olosega were within the occupied area of I. crateriformis, at the time of listing in 2014 (NMFS, 2023, appendix A). Summary of Results for Occupied Areas and Depth Ranges In summary, and based on the new methodology for identifying occupied areas and depth ranges as described above and in the Records Document (NMFS, 2023, appendix A), 18 records groups each provide inadequate evidence that the island where the records were collected was within the occupied area of the listed species at the time of listing, while 27 records groups each provide adequate evidence that the island was within the occupied area of the listed species at the time of listing. These 27 records groups were from 18 islands for A. globiceps, 4 islands for A. retusa, 1 island each for A. speciosa and E. paradivisa, and 3 islands for I. crateriformis (table 2). In addition, the 27 records groups were used to determine the depth ranges of each listed species around each island. For A. globiceps, the depth ranges are 0–20 m (3 islands), 0–12 m (10 islands), and 0–10 m (5 islands). For the other 4 species, the depth ranges are 0–20 m for A. retusa (4 islands) and I. crateriformis (3 islands), and 20–50 m for A. speciosa and E. paradivisa (table 2).

These substantive changes led to other changes in this 83651 proposed rule, including refinement of critical habitat boundaries, and elimination of all proposed exclusions from critical habitat under 4(b)(2). Changes between this and the 2020 proposed rule are summarized in table 3 and described in further detail below.

The islands within the occupied area for each listed coral species are shown in table 2. ** These are the areas for which coral critical habitat was considered, most of which is proposed, for all of the listed coral species combined. *** These are the depth ranges around a given island for all of the listed species found on that island. The depth ranges of each listed species on each island are shown in table 2. khammond on DSKJM1Z7X2PROD with PROPOSALS2 Changes to the Occupied Areas Application of the new methodology for determining the occupied area for each listed species (NMFS, 2023, appendix A) resulted in changes to the numbers of islands included within the occupied areas at the time of listing (2014) for five of the seven listed species in the 2020 proposed rule. For A. globiceps, some new islands were added while some islands that were included in the 2020 proposed rule were removed. For A. jacquelineae, A. retusa, A. speciosa, and S. aculeata, some islands that were included in the 2020 proposed rule were removed. No changes to the islands included within the occupied areas were made for E. paradivisa or I. crateriformis. For A. globiceps, four islands were added to the occupied area that were not in the 2020 proposed rule: Alamagan and Uracas in CNMI, Johnston Atoll in PRIA, and French Frigate Shoals in Hawaii. Also, two islands from the 2020 proposed rule were removed, Anatahan in CNMI and Kingman Reef in PRIA. Since 16 islands were within the occupied area for A. globiceps in the 2020 proposed rule, and 4 new islands have been added while 2 have been removed, this proposed rule includes 18 islands within the occupied area for A. globiceps. These 18 islands are in 5 jurisdictions, including 4 in American Samoa, 1 in Guam, 9 in VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 CNMI, 3 in PRIA, and 1 in Hawaii (table 2). For A. jacquelineae, one island from the 2020 proposed rule was removed, Tutuila and Offshore Banks in American Samoa. Since that was the only island within the occupied area for this species, the range of A. jacquelineae is considered to be entirely outside of U.S. waters. For A. retusa, eight islands from the 2020 proposed rule were removed: Ta’u in American Samoa, Guam, Tinian in CNMI, and Howland, Kingman Reef, Johnston Atoll, Wake Atoll, and Jarvis in PRIA. Since 11 islands were within the occupied area for A. retusa in the 2020 proposed rule, and 8 have been removed, this proposed rule includes 3 islands within the occupied area for A. retusa, all of which are in American Samoa (table 2). For A. speciosa, one island from the 2020 proposed rule was removed, Kingman Reef in PRIA. Since two islands were within the occupied area for A. speciosa in the 2020 proposed rule, and one has been removed, this proposed rule includes one island within the occupied area for A. speciosa, Tutuila and Offshore Banks in American Samoa (table 2). For S. aculeata, two islands from the 2020 proposed rule were removed: Guam and Saipan in CNMI. Since these were the only islands within the occupied area for this species, the range PO 00000 Frm 00009 Fmt 4701 Sfmt 4702 of S. aculeata is considered to be entirely outside of U.S. waters. In conclusion, based on the results of the new methodology, the islands within the occupied areas changed, and therefore the geographical areas occupied by five of the seven listed species have been revised accordingly from the 2020 proposed rule, including: A. jacquelineae, A. globiceps, A. retusa, A. speciosa, and S. aculeata. Since the occupied areas for two of the listed species, A. jacquelineae and S. aculeata, do not include any areas within U.S. jurisdiction, those two species have been removed from this proposed rule. A total of 18 islands are within the occupied area for at least one listed species, including 5 islands with multiple listed species, Tutuila and Offshore Banks (5 species), Ofu-Olosega (3 species), and Ta’u, Rose Atoll, and Wake Atoll (2 species each). The other 13 islands are within the occupied area for A. globiceps only (table 2). Changes to the Depth Ranges The records compiled via the new methodology for determining the occupied area for each listed species (NMFS, 2023, appendix A) also provided new depth range information for all five listed species in this proposed rule. Depth ranges were determined for each listed species around each island within its occupied area. E:\FR\FM\30NOP2.SGM 30NOP2 83652 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS2 For A. globiceps, depth ranges were 0–20 m around all 16 islands considered for this species in the 2020 proposed rule. Based on the updated records, the depth ranges of A. globiceps around the 18 islands within its occupied area are now 0–20 m (3 islands), 0–12 m (10 islands), and 0–10 m (5 islands) (table 2). For A. retusa, depth ranges were 0–10 m around all 11 islands considered for this species in the 2020 proposed rule. Based on the updated records, the depth ranges of A. retusa around the four islands within its occupied area are now 0–20 m (table 2). For A. speciosa, depth ranges were 12–40 m around the two islands considered for this species in the 2020 proposed rule. Based on the updated records, the depth range of A. speciosa around the one island within its occupied area is now 20–50 m (table 2). For E. paradivisa, depth range was 2– 40 m around the one island considered for this species in the 2020 proposed rule. Based on the updated records, the depth range of E. paradivisa around the one island within its occupied area is now 20–50 m (table 2). For I. crateriformis, depth ranges were 0–12 m around the three islands considered for this species in the 2020 proposed rule. Based on the updated records, the depth ranges of I. crateriformis around the three islands within its occupied area are now 0–20 m (table 2). Changes to the Specific Areas In this proposed rule, we refined the boundaries of the specific areas (i.e., areas containing the essential feature of critical habitat for a species) for all species and islands. As a result of additional records collected to develop the proposed critical habitat designation, we obtained new information on habitat preferences indicating that the listed coral species are found entirely or predominantly on certain types of hard substrates but not others. We used that new information along with benthic maps showing the types of hard substrates throughout the occupied areas and depth ranges to delineate the boundaries of the specific areas for each of the listed corals. That is, we used detailed island-scale benthic habitat maps illustrating the variety of hard substrates that occur within the depth ranges of the listed species, together with habitat preference information showing that the listed species occur entirely or predominantly on certain hard substrate types but not on others. Thus, the benthic substrate maps, the habitat preferences, and other site-specific sources of substrate and VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 water quality information were used to delineate the boundaries of the specific areas around each island within the listed species’ occupied areas and depth ranges, as described further in the Specific Areas section. Changes to Areas Excluded From Designation Section 4(b)(2) of the ESA requires that we consider the economic impact, impact on national security, and any other relevant impact, of designating any particular area as critical habitat. The 4(b)(2) analyses in this proposed rule have been updated with new information and data on national security and economic impacts. In particular, the Navy’s exclusion request for six anchorage berths in the Saipan Unit, which was granted in the 2020 proposed rule, is now moot because the depth range of proposed critical habitat is 0–12 m in this unit instead of 0–40 m as in the 2020 proposed rule. That is, the deepest point of critical habitat in this proposed rule in the Saipan Unit is shallower than the shallowest point within any of these six anchorage berths. One national security exclusion request remains in this proposed rule at the Navy’s Ritidian Point Surface Danger Zone Complex on Guam. A full description of the 4(b)(2) analyses is provided in the Application of ESA section 4(b)(2) section of this document. Critical Habitat Identification and Designation In the following sections, we describe the relevant definitions and requirements in the ESA and our implementing regulations, and the key information and criteria used to prepare this proposed critical habitat designation for the five listed corals (A. globiceps, A. retusa, A. speciosa, E. paradivisa, and I. crateriformis). In accordance with section 4(b)(2) of the ESA and our implementing regulations (50 CFR 424.12), this proposed rule is based on the best scientific information available. Our five-step process for identifying critical habitat areas for the threatened corals was to determine the following: (1) the geographical areas occupied by the listed corals at the time of listing (i.e., occupied areas, as well as depth ranges for the listed corals within the occupied areas); (2) the physical or biological features essential to the conservation of the listed corals (i.e., essential feature); (3) whether the physical or biological features within these geographical areas may require special management considerations or protection; (4) the specific areas within each of the occupied areas where the PO 00000 Frm 00010 Fmt 4701 Sfmt 4702 essential features occur (this step consists of four sub-steps); and (5) whether any unoccupied areas are essential to the conservation of any of the corals. Our evaluation and determinations are described in detail in the Information Report (NMFS, 2023) and are summarized below. Geographical Area Occupied by the Species (Occupied Area) The process for determining the occupied areas for the listed corals species is described in the preceding sections. The islands within the occupied area for each of the five listed species are listed in table 2, which include marine habitat around: 18 islands for A. globiceps, 4 islands for A. retusa, 3 islands for I. crateriformis, and 1 island each for A. speciosa and E. paradivisa. The occupied area for each listed species is further defined by its depth range around each island within its occupied area, also shown in table 2. For A. globiceps, the depth ranges are 0– 20 m (3 islands), 0–12 m (10 islands), and 0–10 m (5 islands). For the other 4 species, the depth ranges are 0–20 m for A. retusa (4 islands) and I. crateriformis (3 islands), and 20–50 m for A. speciosa and E. paradivisa (1 island each). The occupied areas for the 5 listed species include a total of 18 islands, 5 of which include overlapping occupied areas for multiple listed species (Tutuila and Offshore Banks, Ofu-Olosega, Ta’u, Rose Atoll, and Wake Atoll). Physical or Biological Features Essential for Conservation Within the occupied areas, critical habitat consists of specific areas in which are found those physical and biological features (PBFs) essential to the conservation of the species and that may require special management considerations or protection. PBFs essential to the conservation of the species are defined as the features that occur in specific areas and that are essential to support the life-history needs of the species, including water characteristics, soil type, geological features, sites, prey, vegetation, symbiotic species, or other features. A feature may be a single habitat characteristic, or a more complex combination of habitat characteristics. Features may include habitat characteristics that support ephemeral or dynamic habitat conditions. Features may also be expressed in terms relating to principles of conservation biology, such as patch size, distribution distances, and connectivity (50 CFR 424.02). E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules Based on the best scientific information available, we identify the following physical feature essential to the conservation of the five corals. Reproductive, recruitment, growth, and maturation habitat. Sites that support the normal function of all life stages of the corals, including reproduction, recruitment, and maturation. These sites are natural, consolidated hard substrate or dead coral skeleton, which is free of algae and sediment at the appropriate scale at the point of larval settlement or fragment reattachment, and the associated water column. Several attributes of these sites determine the quality of the area and influence the value of the associated feature to the conservation of the species: (1) Substrate with presence of crevices and holes that provide cryptic habitat, the presence of microbial biofilms, or presence of crustose coralline algae; (2) Reefscape (all the visible features of an area of reef) with no more than a thin veneer of sediment and low occupancy by fleshy and turf macroalgae; (3) Marine water with levels of temperature, aragonite saturation, nutrients, and water clarity that have been observed to support any demographic function; and (4) Marine water with levels of anthropogenically-introduced (from humans) chemical contaminants that do not preclude or inhibit any demographic function. With regard to the first and second attributes, reef-building corals, including the listed species, require exposed natural consolidated hard substrate for the settlement and recruitment of larvae or asexual fragments. Substrate provides the physical surface and space necessary for settlement of coral larvae, a stable environment for metamorphosis of the larvae into the primary polyp, growth of juvenile and adult colonies, and reattachment of fragments. A number of attributes have been shown to influence coral larval settlement. Positive cues include the presence of crustose coralline algae, biofilms, and cryptic habitat such as crevices and holes. Attributes that negatively affect settlement include presence of sediment and algae (NMFS, 2023). With regard to the third and fourth attributes, reef-building corals, including the listed species, require seawater temperature, aragonite saturation, nutrients, and water clarity conditions within suitable ranges to enable coral growth, reproduction, and recruitment. Corals may tolerate and survive in conditions outside these VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 suitable ranges, depending on the local conditions to which they have acclimatized and the intensity and duration of deviations outside the suitable ranges. Extended deviations from suitable ranges result in direct negative effects on all life stages. The listed corals thrive in warm, clear, nutrient-poor marine waters with calcium carbonate concentrations that allow for symbiont photosynthesis, coral physiological processes and skeleton formation. This water must also have low to no levels of contaminants that would interfere with normal functions of all life stages (NMFS, 2023). Some new information relevant to the essential feature was provided during the public comment period for the 2020 proposed rule or has become available since then, and has been added to the description of the essential feature in the Information Report (NMFS, 2023). The new information did not, however, result in any changes to the definition of the essential feature from the 2020 proposed rule. Need for Special Management Considerations or Protection As described in the Information Report (NMFS, 2023), we determined that the essential feature may require special management considerations or protection throughout the species’ ranges because threats to this feature exist within these areas. Such threats include global and local threats, especially ocean warming, ocean acidification, coral disease, land-based sources of pollution, and fishing. There were no public comments on this section of the Draft Information Report or 2020 proposed rule, nor has any relevant new information become available that would alter our conclusion regarding the potential need for special management considerations or protection. Specific Areas Containing the Essential Feature Within the Geographical Areas Occupied by the Species As described under Geographical Area Occupied by the Species (Occupied Area) and shown in table 2, we identified 18 island units that we considered for proposed coral critical habitat. Each island unit includes occupied habitat for at least one listed coral species. Within each occupied area in each island unit, we delineated more specific areas that contain the essential feature using a 4-step process: (1) general information was used to delineate soft vs. hard substrates; (2) for the hard substrate areas identified in Step 1, specific substrate information PO 00000 Frm 00011 Fmt 4701 Sfmt 4702 83653 was used to delineate unsuitable vs. suitable hard substrates; (3) for the suitable hard substrate areas identified in Step 2, we used water quality information to further delineate suitable vs. unsuitable areas; and (4) from the suitable areas identified in Steps 1–3, we removed any overlapping artificial substrates and managed areas. The 4 steps were implemented for each of the 18 units as follows: (1) For Step 1, we used comprehensive substrate maps developed by PIFSC (PIFSC, 2021) to delineate soft vs. hard substrates, leaving only hard substrate areas within the combined depth ranges of all listed species in each unit, except for Wake Atoll and FFS, for which PIFSC (2021) did not produce maps. For Wake Atoll, we used the substrate map from the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) (PIBHMC 2021). For French Frigate Shoals, we used the geomorphological structure component of the maps developed by National Centers for Coastal and Ocean Sciences (NCCOS) (NCCOS, 2003). (2) For Step 2, we started with the hard substrate areas identified in Step 1, then distinguished unsuitable vs. suitable hard substrates. Many hard substrates are unsuitable because: (1) highly-fluctuating physical conditions cause frequent and extreme environmental changes (e.g., high tide surge vs. low tide sun exposure on many reef flat substrates); (2) water motion continuously mobilizes sediment (e.g., pavement with sand channels) or unstable substrate (e.g., rubble); or (3) flat, low-relief areas provide poor settlement and growth habitat (e.g., pavement). Removal of these areas left suitable hard substrates, including spur-and-groove, individual patch reef, aggregate reef, aggregated patch reef, scattered coral/rock, and rock/boulder. For this step, primary information sources were Brainard et al. (2008, 2012, 2019), NCCOS (2003, 2005, 2010), PIBHMC (2021), PIFSC (2021), the detailed public comment letters from the Territories (AS DMWR 2021, Guam DOAG 2021, CNMI DLNR 2021), and the American Samoa, Guam, CNMI, PRIA, and Northwestern Hawaiian Islands (NWHI) chapters in Waddell and Clarke (2008). Additional sources for individual units are cited in the unit sections in the Information Report (NMFS, 2023). (3) For Step 3, starting with the suitable hard substrate areas identified in Step 2, we used water quality information to further delineate suitable vs. unsuitable areas. Unsuitable areas are those with water quality conditions that chronically fall outside of suitable E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 83654 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules ranges. For example, some of the areas identified in Step 2 are nearly constantly exposed to pollution such as excessive nutrients, excessive sediment (i.e., more than a thin veneer), or contaminants, making them unsuitable. Generally, such areas occur in enclosed lagoons and inner harbors where there is high runoff and limited water circulation. Outside of such areas, point and non-point sources of pollution generally do not overlap with suitable hard substrates because wastewater outfalls are located on soft substrates beyond the reef slopes, and stormwater and freshwater discharges occur primarily on soft substrates (sand or mud) or unsuitable hard substrates (pavement or rubble) along or near shorelines. For this step, primary information sources were Brainard et al. (2008, 2012, 2019), EPA (2021a–f), the detailed public comment letters from the Territories (AS DMWR, 2021, Guam DOAG, 2021, CNMI DLNR, 2021), Territory water quality assessments (AS EPA, 2020, CNMI BECQ, 2018), and sources for individual units cited in the Information Report (NMFS, 2023). (4) For Step 4, from the suitable areas identified via the above three steps, we removed any artificial substrates and managed areas, because they do not provide the essential feature. ‘‘Managed areas,’’ for the purposes of this proposed rule, are specific areas where the substrate has been persistently disturbed by planned management authorized by local, state, or Federal governmental entities at the time of critical habitat designation, and expectations are that the areas will continue to be periodically disturbed by such management. Examples include, but are not necessarily limited to, all harbors and their entrance channels, navigation channels, turning basins, and berthing areas that are periodically dredged or maintained. This only applies to existing artificial substrates and managed areas, not proposed or planned artificial substrates and managed areas. The resulting specific areas are where we consider the essential feature to be distributed currently within each island unit and depth range, based on the best available information. However, on smaller spatial scales, there are likely locations within the specific areas that lack the essential feature, and the exact locations with and without the essential feature are likely to change somewhat over time in response to changing conditions. Thus, the specific areas described below are intended to delineate areas containing the essential feature, rather than areas made up completely and permanently of the VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 essential feature. As described in detail in the Information Report (NMFS, 2023), these 4 steps were applied to each of the 18 units to delineate the specific areas of proposed coral critical habitat in more detail than in the 2020 proposed rule. Unoccupied Critical Habitat Areas Section 3(5)(A)(ii) of the ESA authorizes the designation of specific areas outside the geographical area occupied by the species (referred to here as ‘‘unoccupied areas’’), if those areas are determined to be essential for the conservation of the species. Our regulations at 50 CFR 424.12(b)(2) require that we first evaluate areas occupied by the species, and only consider unoccupied areas to be essential where a critical habitat designation limited to geographical areas occupied would be inadequate to ensure the conservation of the species. To evaluate unoccupied areas that may qualify as critical habitat, we first considered the ranges at the time of listing of the five coral species that occur in areas under U.S. jurisdiction (NMFS 2023). The best available data provides no evidence that those occupied areas have been reduced from the historical ranges for any of the five listed species. Areas within U.S. jurisdiction that are outside the occupied ranges and that could serve as habitat for these species represent <1% of the area of each of their current ranges. Because these species still occupy their historical ranges, the feature essential to their conservation is present in these areas, and the unoccupied areas represent a very small amount of potential habitat, we find the occupied areas adequate to ensure the conservation of the species (NMFS, 2023). Thus, we are not proposing to designate any unoccupied areas within U.S. jurisdiction as critical habitat. The impacts of global climate change-related threats (especially ocean warming and ocean acidification) to the listed corals and their habitats are projected to substantially worsen in the foreseeable future, which may result in range shifts for some or all of the 5 listed coral species, as well as the other 10 species of corals that occur outside U.S. jurisdiction. For the five species occurring within U.S. waters, the areas outside their occupied ranges mostly occur along the northern edges of their ranges, thus ocean warming could make the ocean temperatures of these areas more suitable for the listed species in the foreseeable future. In contrast, ocean acidification is likely to have the opposite effect, causing ocean pH levels along the northern fringes of the species’ PO 00000 Frm 00012 Fmt 4701 Sfmt 4702 ranges to become less suitable (Brainard et al. 2011, NMFS 2014). However, it is not possible to determine where such changes are likely to happen, and how they would affect any of the listed species’ habitat. We also considered whether these conclusions would differ under the regulations that were in effect prior to the revisions to the regulations in 50 CFR 424.12(b)(2) in 2019 (see 84 FR 45020, August 27, 2019). We conclude that while our analysis would necessarily differ, the decision not to propose designating any unoccupied areas would not be any different. Because the five coral species each still occupy their historical ranges, the feature essential to their conservation is present in these areas, and unoccupied areas represent a very small amount of potential habitat, we cannot conclude that any unoccupied areas are essential to their conservation. Application of ESA Section 4(a)(3)(B)(i) (INRMPs) Section 4(a)(3)(B)(i) of the ESA prohibits designating as critical habitat any lands or other geographical areas owned or controlled by the Department of Defense (DOD), or designated for its use, that are subject to an Integrated Natural Resources Management Plan (INRMP) prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if the Secretary of Commerce determines in writing that such plan provides a benefit to the species for which critical habitat is proposed for designation. Two INRMPs are applicable to the proposed coral critical habitat: (1) The Navy’s Joint Region Marianas INRMP (JRM INRMP), finalized and signed in 2019 (DON, 2019a); and (2) the Air Force’s INRMP for Wake Island Air Field, Wake Atoll, Kokee Air Force Station, Kauai, Hawaii, and Mt. Kaala Air Force Station, Oahu, Hawaii (Wake INRMP), finalized and signed in 2023 (USAF, 2023a). The JRM INRMP is a composite of management plans for many distinct DOD-controlled areas in the Mariana Islands, including areas in Guam, Tinian, and FDM (DON, 2019a). Summaries of the analyses in the Information Report (NMFS, 2023) of whether these two INRMPs are likely to benefit the ESA-listed corals or their habitat in Guam and CNMI (JRM INRMP) and Wake (Wake INRMP) are provided below. The analyses address the four considerations outlined in our implementing regulations at 50 CFR 424.12(h). These four considerations are: (1) the extent of the area and essential feature present in the area; (2) The type and frequency of use of the area by the listed species; (3) The E:\FR\FM\30NOP2.SGM 30NOP2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS2 relevant elements of the INRMP in terms of management objectives, activities covered, and best management practices, and the certainty that the relevant elements will be implemented; and (4) The degree to which the relevant elements of the INRMP will protect the habitat (essential feature) from the types of effects that would be addressed through a destruction-or-adversemodification analysis under section 7 of the ESA. JRM INRMP—Guam In Guam, the JRM INRMP encompasses three marine areas (hereafter ‘‘INRMP marine areas’’) that include potential proposed coral critical habitat for the one listed coral that occurs in the Mariana Islands, A. globiceps: (1) Naval Base Guam—Main Base (NBG Main Base) Submerged Lands; (2) Naval Base Guam— Telecommunications Site (NBG TS) Submerged Lands; and (3) Andersen Air Force Base (AAFB) Submerged Lands. A summary of the analyses of whether the INRMP is likely to benefit the habitat of A. globiceps in each of these three INRMP marine areas is provided below, from the full analyses in the Information Report (NMFS, 2023). With regard to the extent of the area and essential feature present: (1) the NBG Main Base Submerged Lands cover approximately 30,000 acres (12,100 hectares) along the coastline from Orote Peninsula to Asan (described in the JRM INRMP, section 5.3, DON, 2019a); (2) the NBG TS Submerged Lands cover approximately 19,500 acres on the northwestern side of Guam (described in the JRM INRMP, section 8.3, DON, 2019a); and (3) AAFB Submerged Lands cover approximately 26,500 acres (10,700 hectares) of Submerged Lands on the northern side of Guam (described in the JRM INRMP, section 9.3, DON, 2019a). Each of the three INRMP marine areas include extensive habitat for A. globiceps (NMFS, 2023). The potential critical habitat within the three INRMP marine areas includes both the substrate and water quality components of the essential feature of coral critical habitat (i.e., characteristics of substrate and water quality to support coral life history, including reproduction, recruitment, growth, and maturation), based on information provided in the Guam section of the Information Report (NMFS, 2023) and the INRMP (DON, 2019a). With regard to the relevant elements of the INRMP, and the certainty that the relevant elements will be implemented, the two parts of this step are addressed separately below. The relevant elements of the JRM INRMP for each INRMP VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 marine area include: (1) for the NBG Main Base Submerged Lands, the INRMP includes a Coral Habitat Enhancement Plan (section 5.4.2.1), consisting of eight specific actions in three categories (three monitoring and adaptive management actions, three collaboration with local partners actions, and two reduction of vessel impacts actions); (2) for NBG TS Submerged Lands, the INRMP includes a Coral Habitat Enhancement plan (section 8.4.2.1), consisting of a similar set of eight specific actions as for NBG Main Base; and (3) for AAFB Submerged Lands, the INRMP includes a Coral Habitat Enhancement plan (section 9.4.2.1), consisting of a similar set of seven specific actions as for NBG Main Base, except that there is less focus on reduction in vessel impacts because of the much lower vessel traffic there. The actions, projects, and updates through the end of 2023 are described in detail in the Information Report (NMFS, 2023). NMFS concludes that the Navy will implement the relevant elements of the JRM INRMP for the previously described three INRMP marine areas for three reasons: (1) Clear and Recent Documentation— the 2019 JRM INRMP includes Coral Habitat Enhancement plans for INRMP marine areas in Guam, with clear strategies and actions that address the habitat conservation needs of ESA-listed corals within these areas. The JRM INRMP’s appendix D also includes annual reports describing how coral conservation efforts had been implemented in the years leading up to the 2019 final INRMP. These coral habitat conservation plans, as well as progress reports from the most recent years (DON, 2019b, 2020, 2021a,b,c,d, 2023), clearly articulate how the Navy is conserving coral habitat within the INRMP marine areas in Guam, and how it is planning to do so in the future. (2) Demonstration of Good Faith Efforts for Listed Corals—the Navy has already implemented coral habitat conservation projects that are beneficial to ESA-listed corals within some INRMP marine areas in Guam, as described in the INRMP itself and its appendix D (DON, 2019b), as well as progress reports (DON, 2019b, 2020, 2021a,b,c,d, 2023). Many of these projects have been ongoing for several years and are proactive, in that they were not required of the Navy by the ESA. (3) History of Strong Conservation Work—in our experience working with the Navy on the development of the marine resource components of its 2013 and 2019 final INRMPs (DON, 2013, 2019a), we have found the Navy to be successful at carrying out marine habitat PO 00000 Frm 00013 Fmt 4701 Sfmt 4702 83655 conservation work on Guam, and that it often takes the initiative on conservation efforts whether requested by NMFS or not. For example, many of the coral habitat conservation projects in the 2019 JRM INRMP (DON, 2019a) and progress reports (DON, 2019b, 2020, 2021a,b,c,d, 2023) had already been started by the Navy before corals were listed in 2014, and were being done to improve conservation of marine resources on the island, regardless of whether they were required by Federal statute or not. The coral habitat enhancement elements of the JRM INRMP described previously are expected to substantially reduce the types of effects within the three INRMP marine areas in Guam that would be addressed through the destruction-or-adverse-modification analysis. The Navy would accomplish this primarily by using the results of its own monitoring program to develop and implement management measures to minimize the impacts of the Navy’s actions in Guam on coral habitat within the INRMP marine areas. Thus, implementation of the JRM INRMP is likely to provide substantial protection to the essential feature of coral critical habitat (reproductive, recruitment, growth, and maturation habitat) within the Guam INRMP marine areas from the types of effects that would be addressed through critical habitat consultation (DON, 2021a,b,d, 2023). JRM INRMP—CNMI In CNMI, the JRM INRMP encompasses two marine areas that include potential proposed coral critical habitat for the one listed coral that occurs in the Mariana Islands, A. globiceps: (1) the Tinian Marine Lease Area (Tinian MLA) Submerged Lands; and (2) the Farallon de Medinilla (FDM) Submerged Lands (DON, 2019a). A summary of the analyses of whether the INRMP is likely to benefit the habitat of A. globiceps in each of these two INRMP marine areas is provided below, from the full analyses in the Information Report (NMFS, 2023). With regard to the extent of the area and essential feature present: (1) the Tinian MLA Submerged Lands cover approximately 47,500 acres (19,200 hectares) surrounding the northern portion of Tinian (described in the JRM INRMP, section 11.3, DON, 2019a); (2) the FDM Submerged Lands consists of approximately 25,000 acres (10,100 hectares) surrounding FDM (described in the JRM INRMP, section 12.3, DON, 2019a). Most or all of the potential critical habitat within the two INRMP marine areas includes both the substrate and water quality components of the E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 83656 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules essential feature of coral critical habitat (i.e., characteristics of substrate and water quality to support coral life history, including reproduction, recruitment, growth, and maturation), based on information provided in the Tinian and FDM sections of the Information Report (NMFS, 2023) and the INRMP (DON, 2019a). With regard to the relevant elements of the INRMP, and the certainty that the relevant elements will be implemented, the two parts of this step are addressed separately below. The relevant elements of the JRM INRMP for each INRMP marine area include: (1) for the Tinian MLA Submerged Lands, the INRMP includes a Coral Habitat Enhancement plan, consisting of three specific actions to enhance coral habitat by monitoring health and acute impacts (section 11.4.2.1; DON, 2019a); and (2) for the FDM Submerged Lands, the INRMP includes marine habitat management actions, consisting of surveys and mapping of ESA-listed corals, coral reef, and other marine habitats within the area (section 12.4.2; DON, 2019a). The INRMP also includes an assessment of ESA-listed corals, as required by the 2015 biological opinion on the Navy’s Mariana Islands Testing and Training program (section 12.4.2.2; DON, 2019a). The actions, projects, and updates through the end of 2021, are described in detail in the Information Report (NMFS, 2023). NMFS concludes that the Navy will implement these relevant elements of the JRM INRMP for three reasons: (1) Clear and Recent Documentation— the 2019 JRM INRMP includes Coral Habitat Enhancement plans for INRMP marine areas in CNMI (Tinian MLA, FDM Submerged Lands), with clear strategies and actions that address the habitat conservation needs of ESA-listed corals within these areas. The JRM INRMP’s appendix D also includes annual reports describing how coral conservation efforts had been implemented in the years leading up to the 2019 final INRMP. These coral habitat conservation plans, as well as progress reports from the most recent years (DON, 2019b, 2020, 2021a,b,c,d, 2023), clearly articulate how the Navy is conserving coral habitat within the INRMP marine areas in CNMI, and how it will do so in the future. (2) Demonstration of Good Faith Efforts for Listed Corals—the Navy has already implemented coral projects that have the potential to benefit the habitat of ESA-listed corals within INRMP marine areas in CNMI (Tinian MLA, FDM Submerged Lands). For example, coral species presence and abundance surveys were conducted within the VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 Tinian MLA in 2013 (Tetra Tech, 2014) and 2017 (DON, 2017), and around FDM in 2012 (Smith and Marx, 2016), 2017 (Carilli et al., 2018), and 2022 (DON 2023). These surveys have the potential to benefit the habitat of ESA-listed corals by providing the information needed to better protect these areas in the future. (3) History of Strong Conservation Work—the Navy has a long history of carrying out successful marine habitat conservation work in the Mariana Islands and often takes the initiative on conservation efforts whether requested by NMFS or not. For example, many of the coral habitat conservation projects in the 2019 JRM INRMP (DON 2019a) and progress reports (DON, 2019b, 2020, 2021a,b,c,d, 2023) had already been started by the Navy before corals were listed in 2014. These projects were conducted to improve the conservation of marine resources on the island, regardless of whether they were required by Federal statute or not. While the majority of these projects have been implemented in Guam rather than CNMI, the JRM INRMP includes many plans for CNMI (as noted above), and the same Navy command (Joint Region Marianas) is responsible for carrying out such work in both Guam and CNMI. The coral habitat enhancement elements of the JRM INRMP described above will substantially reduce the types of effects within the INRMP marine areas in CNMI that would be addressed through the destruction-oradverse-modification analysis. The Navy would accomplish this primarily by using the results of its own monitoring program to develop and implement management measures to minimize the impacts of the Navy’s actions in CNMI on coral habitat within the INRMP marine areas. Thus, implementation of the JRM INRMP is likely to provide substantial protection to the essential feature of coral critical habitat (reproductive, recruitment, growth, and maturation habitat) within the CNMI INRMP marine areas from the types of effects that would be addressed through critical habitat consultation (DON 2021a,c,d, 2023). Wake INRMP On Wake Atoll, the Wake INRMP (USAF, 2023a) encompasses the entire area considered for coral critical habitat for the two listed corals on the atoll, A. globiceps and A. retusa, as described in the Information Report (NMFS, 2023). A summary of the analyses of whether the INRMP is likely to benefit the habitat of ESA-listed corals in this INRMP marine area is provided below, from the full PO 00000 Frm 00014 Fmt 4701 Sfmt 4702 analyses in the Information Report (NMFS, 2023). With regard to the extent of the area and essential feature present, the Wake INRMP marine area includes nearly 500,000 acres (202,300 hectares) of Submerged Lands and waters within the lagoon and surrounding the atoll out to 12 nautical miles (22.2 km) from the mean low water line (USAF, 2023a), and thus includes all reef-building corals and coral reefs associated with the atoll. Most or all of the potential critical habitat within the INRMP marine area includes both the substrate and water quality components of the essential feature of coral critical habitat (i.e., reproductive, recruitment, growth, and maturation habitat provided by suitable substrate and suitable water quality), based on information provided in the Wake section of the Information Report (NMFS, 2023) and the INRMP (USAF, 2023a). With regard to the relevant elements of the INRMP, and the certainty that the relevant elements will be implemented, the two parts of this step are addressed separately below. The relevant element of the Wake INRMP is the coral conservation component that was added to the INMRP in 2017 (Appendix K, Coral Conservation Actions at Wake Atoll; USAF, 2023a), which is made up of four groups of actions, each of which includes multiple projects: Water quality improvements (six projects), education and outreach (two projects), fisheries management (four projects), and physical DOD presence on Wake Atoll (three projects; USAF, 2023a). The actions, projects, and updates through the end of 2021, are described in detail in the Information Report (NMFS, 2023). NMFS concludes that the Air Force will implement these relevant elements of the Wake INRMP for three reasons: (1) Clear and Recent Documentation— the Wake INRMP includes a coral conservation plan (USAF, 2023a) with a 4-pronged strategy (water quality improvement, outreach and education for Wake-based staff, fisheries management, and physical DOD presence on Wake Atoll, i.e., restriction of access and overall natural resource management) that comprehensively addresses the conservation needs of ESA-listed corals on Wake Atoll. This coral conservation plan clearly articulates how U.S. Air Force (USAF) is conserving corals on Wake, and how it will do so in the future. The ongoing implementation of the Wake INRMP is reported via progress updates and reviews (USAF, 2018, 2019, 2021a,b, 2023b). (2) Demonstration of Good Faith Efforts for Listed Corals—In the years E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules leading up to the final Wake INRMP (USAF, 2023a), USAF implemented projects on Wake related to each of its 4-pronged coral conservation strategy, as explained in appendix S of the Wake INRMP. For water quality improvement, in 2016 USAF began implementation of both the stormwater pollution prevention and invasive plant control projects. For outreach and education, in 2016 USAF revised the Wake Island Dive Club Charter to further reduce the potential impacts of recreational activities on corals. For fisheries management, in 2017 USAF updated its fishing rules, which are part of the Wake Island Operating Guidance, to prohibit the use of (1) cast nets on the exterior of the atoll, (2) anchoring on coral reef habitat, and (3) and trolling over coral reef habitat. For physical DOD presence on Wake Atoll, in 2016 USAF funded and provided logistical support for a Fish and Wildlife Service (FWS) coral survey that documented two ESA-listed corals on the atoll for the first time. Since 2017, USAF has implemented projects on Wake for each of its 4pronged coral conservation strategy, as noted above in the 2021 updates, and detailed in the progress updates and reviews (USAF, 2018, 2019, 2021a,b, 2023b). (3) History of Strong Conservation Work—USAF has a long history of carrying out successful conservation work on Wake and often takes the initiative on conservation efforts whether requested by NMFS or not. For example, many of the projects in the INRMP’s coral conservation strategy had already been started by USAF before corals were listed in 2014, and were being done to improve the conservation of marine and terrestrial resources on the atoll, regardless of whether they were required by Federal statute or not. Likewise, in 2016, USAF funded and supported the FWS coral survey of the atoll, leading to the discovery that the two ESA-listed corals occur on the atoll. In addition, USAF has historically been a strong conservation partner with NMFS, supporting a wide variety of marine and terrestrial conservation projects, and actively engaging both agencies in the INRMP planning and implementation process, as described in the progress updates and reviews (USAF, 2018, 2019, 2021a,b, 2023b). The coral conservation component of the Wake INRMP (Appendix K, Coral Conservation Actions at Wake Atoll; USAF, 2023a) is expected to reduce both direct and indirect impacts to listed corals via minimization or avoidance of recreational impacts (fishing, diving, anchoring), and terrestrial impacts (i.e., run-off from VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 land-based activities), thereby addressing two of the primary threats to listed corals (fishing and land-based sources of pollution). That is, the coral conservation elements of the Wake Atoll INRMP described previously are expected to substantially reduce the types of effects at Wake Atoll that would be addressed through the destruction-oradverse-modification analysis. Based on the fact that the Wake INRMP’s coral conservation strategy is well-designed to reduce impacts to listed corals, and also that recent progress updates and reviews (USAF, 2018, 2019, 2021a,b, 2023b) demonstrate substantial progress with the implementation of the strategy, we determined that the Wake INRMP provides a benefit to listed corals, and their critical habitat (reproductive, recruitment, growth, and maturation habitat). Conclusion Regarding Areas Subject to INRMPs Based on the analyses summarized previously and provided in the Information Report (NMFS, 2023), we conclude both the JRM INRMP (DON, 2019a) and the Wake INRMP (USAF, 2023a) provide a conservation benefit to the listed corals and their habitats within all INRMP marine areas on Guam, CNMI, and Wake. Thus, the potential coral critical habitat areas within the INRMP marine areas on Guam, Tinian, FDM, and Wake are ineligible for designation as critical habitat. Application of ESA Section 4(b)(2) Section 4(b)(2) of the ESA requires that we consider the economic impact, impact on national security, and any other relevant impact, of designating any particular area as critical habitat. Additionally, the Secretary has the discretion to consider excluding any area from critical habitat if they determine that the benefits of exclusion (that is, avoiding some or all of the impacts that would result from designation) outweigh the benefits of designation based upon the best scientific and commercial data available. The Secretary may not exclude an area from designation if exclusion will result in the extinction of the species. The following sub-sections summarize the economic, national security, and other relevant impacts analyses in the Information Report (NMFS, 2023) that we projected would result from proposed coral critical habitat. We considered these impacts when deciding whether to exercise our discretion to exclude particular areas from the designation. Both positive and PO 00000 Frm 00015 Fmt 4701 Sfmt 4702 83657 negative impacts were identified and considered (these terms are used interchangeably with benefits and costs, respectively). Impacts were evaluated in quantitative terms where feasible, but qualitative appraisals were used where that is more appropriate. The primary impacts of a critical habitat designation result from the ESA section 7(a)(2) requirement that Federal agencies ensure that their actions are not likely to result in the destruction or adverse modification of critical habitat and that they consult with NMFS in fulfilling this requirement. The impacts of designating coral critical habitat are only those that would be in addition to the impacts of listing (i.e., incremental impacts). The distribution of listed corals within critical habitat strongly influences the extent of incremental impacts. That is, the more colonies of listed corals that are distributed throughout coral critical habitat, the lower the proportion of Federal actions that would affect critical habitat but not listed corals, and thus the lower the incremental impacts of critical habitat designation. As described in section 3.3.19 of the Information Report (NMFS, 2023), colonies of listed corals are generally distributed throughout the specific areas being considered for proposed coral critical habitat, thus the incremental impacts are expected to be quite low. Summaries of the economic, national security, and other relevant impact analyses in the Information Report (NMFS, 2023) are provided below. The analyses follow the guidance for 4(b)(2) analyses provided in our 2016 policy (81 FR 7226, February 11, 2016) and regulations at 50 CFR 424.19. 4(b)(2) Economic Impact Analysis The economic impacts of designating the areas identified as coral critical habitat are analyzed in the full 4(b)(2) Economic Impact Analysis document, completed in late 2021, which is appendix C of the Information Report (NMFS, 2023). Economic impacts are projected for the 10-year period 2022– 2031, and uncertainty is accounted for by using low-end and high-end scenarios to estimate incremental impacts. The Economic Impact Analysis Report (NMFS, 2023, appendix C) presents economic impacts in terms of present value versus annualized costs. For example, table 17 of the report summarizes the low-end estimated cost of coral critical habitat as $373,171 in terms of the present value of the total cost over the 10-yr period of 2022–2031, with an estimated annualized cost of $53,131 over that 10-yr period. Present value over the 10-year period is not E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 83658 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules simply 10 times the annualized cost because present value represents the sum of a series of past or future cash flows discounted at a specified discount rate (in this case, 7 percent) and expressed in constant dollars, whereas annualized cost provides a comparison of impacts across activities with varying forecast periods (NMFS, 2023, appendix C). For the low-end scenario, total incremental costs over the 10-year period are estimated at $373,171 for all jurisdictions combined or $53,131 annualized. These are entirely administrative costs since the low-end scenario assumes that no project modifications would be required. For the high-end scenario, total incremental costs over the 10-year period are estimated at $6,815,860 for all jurisdictions combined or $970,425 annualized. Of these costs, 95 percent are derived from project modifications because, for purposes of this analysis, the high-end scenario assumes that 100 percent of section 7 consultations will be formal consultations that result in the need for project modifications to avoid destruction or adverse modification of the critical habitat. The jurisdiction with the highest economic impacts in both scenarios is Guam, due to the relatively high number of expected consultations there (NMFS, 2023). While the low-end vs. high-end scenarios are useful for illustrating the range of potential economic impacts, the following points are relevant to interpreting the results: (1) Both scenarios assumed that proposed coral critical habitat would be 0–50 m depth around all island units considered in proposed coral critical habitat; however, proposed coral critical habitat is 0–50 m depth on just one island (Tutuila) and 0–20 m, 0–12 m, and 0–10 m on the others. (2) Colonies of listed corals occur within all specific areas being considered for proposed coral critical habitat (NMFS, 2023, appendix A), thus reducing incremental impacts. That is, since colonies of listed corals occur in all specific areas of proposed coral critical habitat, there would be a low proportion of future Federal actions that would affect critical habitat but not listed corals. As the proposed coral critical habitat will not include extensive areas where listed coral colonies are absent, the incremental impacts of proposed coral critical habitat are likely to be quite low, which minimizes economic impacts. (3) A comparison of projected vs. actual consultations in 2016–2019 was included in the economic analysis done for the 2020 proposed coral critical VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 habitat rule (NMFS 2020, appendix B), which showed that three times more formal consultations were projected in the high-end scenario than actually occurred. That is, the reality of consultations was more similar to the low-end scenario than the high-end scenario. For these reasons, it is reasonable to conclude that the actual economic impacts are likely to be much closer to those projected in the low-end scenario than the high-end scenario. In addition, economic benefits would be relatively high in the high-end scenario (because project modifications would provide better protection of coral reef ecosystems, which produce economic benefits, as described in section 5.1.6 of the Information Report (NMFS, 2023), but lower in the low-end scenario (because there would be no project modifications, and thus no increased protection of coral reef ecosystems). 4(b)(2) National Security Impact Analysis We received a request from the Department of the Navy (Navy) to exclude one site based on national security impacts: The portion of the Navy’s Ritidian Point Surface Danger Zone (SDZ) Complex outside of DOD Submerged Lands on Guam. For this site, we weighed the national security impacts of designating the site as critical habitat against the conservation benefits to the listed corals of designating the site as critical habitat. If impacts to national security outweigh the benefits of including an area in the designation, the Secretary may exercise her discretion to exclude that particular area from critical habitat. If the benefits of including the area in the designation outweigh the impacts to national security, however, the site cannot be considered for exclusion from critical habitat (81 FR 7226, February 11, 2016). The Ritidian Point SDZ complex overlaps with a small area of forereef identified for potential designation as coral critical habitat. The area is 0–12 m of depth and consists primarily of spurand-groove and aggregate reef that provides high quality coral habitat. A species-level coral survey conducted in 2021 at this site indicated that A. globiceps was present, finding a total of four colonies along eight 50-m transects at 6 m depth within forereef habitat at the site. In contrast, a species-level coral survey conducted in 2006 at this site did not find any A. globiceps colonies along a different set of eight 50-m transects between 1 and 20 m within forereef and reef flat habitat (NMFS, 2023). PO 00000 Frm 00016 Fmt 4701 Sfmt 4702 National security impacts depend on the additional section 7 requirements that would result from the coral critical habitat, above and beyond those already required to avoid jeopardizing the continued existence of any listed species or avoid destruction or adverse modification of other, designated critical habitats (i.e. incremental impacts). The Navy noted that the Ritidian Point SDZ complex supports training at the Marine Corps Live Fire Training Range Complex (LFTRC) at AAFB, and construction of new facilities (e.g., range administration building, range maintenance building, and observation towers) at AAFB, to meet the individual weapons training/ qualification requirements of the Marine Corps. This SDZ is expected to be operational for 32 weeks per year and extends approximately 2 miles over open water in the event stray bullets go over the berm and into the ocean. If this occurs, the bullets will settle on the seafloor (NMFS, 2023). The Navy stated that designation of the marine component of this site as coral critical habitat would result in limitations on live fire training at LFTRC. The Navy explained that such limitations would occur because limited staff time and resources would be diverted to preparing additional documents required to implement activities in critical habitat areas from work required on other vital environmental items. In 2021 and 2022, the Navy confirmed that this information is still applicable to the site. Because many training and construction activities are planned at LFTRC adjacent to this marine area, the listed coral A. globiceps occurs there, and the planned activities have the potential to affect this listed species, ESA section 7 consultations would likely be necessary whether critical habitat is designated or not. That is, the additional consultation requirement above and beyond what would already be required by the fact that listed corals occur at the site is not expected to be substantial. Also, the additional consultation for critical habitat would be for activities that are planned in advance, and thus the additional section 7 consultation workload would not be unpredictable but rather could be anticipated and managed ahead of time. The Navy noted that the individual live fire training for Marine Corps personnel at the LFTRC on Guam is a prerequisite for conducting unit level and combined level training. The Navy further explained that without the qualification of these live fire training events, individuals and small teams are not capable of conducting larger unit E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules collective events, and that the LFTRC provides the necessary foundation for which training progression is built upon. Plans are in place to considerably expand LFTRC in anticipation of growing Marine Corps training needs. No other facility on Guam or elsewhere in the Mariana Islands provides this type of training. In 2021 and 2022, the Navy confirmed that this information is still applicable to the site (NMFS, 2023). In determining benefits to the conservation of ESA-listed corals we considered whether designation of critical habitat at the particular site would lead to additional conservation of the species beyond what is already provided by the species’ listing. The potential for additional conservation at a given site is a function of the listed corals’ use of the area, the level of protection already provided by existing management (e.g., the site is entirely within Guam National Wildlife Refuge), and the likelihood of non-DOD actions that are likely to affect the area and that are subject to the consultation requirements of section 7. As elsewhere on Guam, the coral reef habitat within the area being considered for proposed coral critical habitat is made up of forereef from 0—12 m depth, consisting primarily of spur-andgroove and aggregate reef. As noted above, A. globiceps occurs at this site. However, colonies of the species may die off in response to natural disturbances and not reappear for a few years, which may be why the 2021 survey found A. globiceps there but the 2006 survey did not despite surveying within the same habitat and depth range. Such mortality and recovery and associated disappearance and reappearance of coral populations at any given site is a normal response to natural disturbance. Critical habitat protects the essential feature whether colonies of the listed coral species occur at the site at the time of consultation or not. The area being considered for potential designation as coral critical habitat is entirely within U.S. Fish and Wildlife Service (USFWS) Submerged Lands, which forms the marine component of the Guam National Wildlife Refuge (NWR), and is managed according to the Guam NWR Comprehensive Conservation Plan. The plan includes Strategies to Restore, Protect, and Maintain Native Marine Communities, such as marine debris removal and area closures. The site is also entirely within Essential Fish Habitat (EFH) for coral reef ecosystems, but EFH protections are not mandatory (NMFS, 2023). VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 It is possible that non-DOD Federal actions will be proposed within this site that could affect the essential feature (e.g., actions proposed by USFWS), but that would no longer be subject to the critical habitat provision if the particular area were excluded from the designation. When the site is not closed by the SDZ, non-DOD actions could potentially occur there, for example those permitted or carried out by USFWS. Although such actions would presumably be consistent with the Guam NWR Comprehensive Conservation Plan (USFWS 2009), they may affect the essential feature (NMFS, 2023). Based on the considerations described above, we conclude that the impacts to national security of including this area within critical habitat do not outweigh the conservation benefits to the listed corals, and thus do not propose to exclude the Ritidian Point SDZ complex from proposed coral critical habitat designation. The most important factors supporting this recommendation are: (1) the national security impacts of coral critical habitat are unlikely to be either substantial or unpredictable because listed corals are known to occur at this site at least some of the time, meaning that the Navy would already be conducting section 7 consultations on listed corals for any of their activities that may affect listed corals at this site even without critical habitat, resulting in little additional consultation work; and (2) the conservation benefits of coral critical habitat could be considerable because critical habitat would provide additional protection of the high quality essential feature that is found throughout the area from future proposed Federal actions (NMFS, 2023). Other Relevant Impacts Other relevant impacts include the benefits of critical habitat designation and impacts on governmental or private entities that are implementing existing management plans that provide benefits to the listed species. The three main types of benefits of critical habitat designation are increased protection of the essential feature from Federal actions, ecosystem service benefits of coral reef conservation, and education and awareness. Critical habitat is habitat needed to support recovery of listed species. That is, the most direct benefits of the critical habitat designation stem from the increased protection of the essential feature from Federal actions. While listed corals are generally distributed throughout the specific areas, there are still many locations within the specific areas that lack colonies of listed corals PO 00000 Frm 00017 Fmt 4701 Sfmt 4702 83659 at any given point in time due to natural spatial and temporal fluctuations of coral colony presence. That is, individual colonies of listed corals may decrease or disappear from particular locations in response to local disturbances, then return and increase as local conditions improve. Such dynamic spatial and temporal fluctuations in the distribution of colonies of listed corals within the specific areas is a natural process. Critical habitat thus protects the essential feature in locations and during times when specific areas lack colonies of listed corals and Federal actions are proposed at that location (NMFS, 2023). Overall, coral reef ecosystems, including those comprising populations of the listed corals, provide important ecosystem services of value to individuals, communities, and economies. These include recreational opportunities (and associated tourism spending in the regional economy), habitat and nursery functions for recreationally and commercially valuable fish species, shoreline protection in the form of wave attenuation and reduced beach erosion, and climate stabilization via carbon sequestration. As of 2021, the total economic value of coral reefs in the three U.S. Pacific Islands jurisdictions where the great majority of critical habitat is being proposed is (1) American Samoa—$13.4 million/year, (2) Guam—$165.0 million/year, and (3) CNMI—$60.4 million/year (NMFS, 2023). Efforts to conserve the listed corals also benefit the broader reef ecosystems, thereby preserving or improving these ecosystem services and values (NOAA Coral Reef Conservation Program, 2013). While we cannot quantify the precise economic benefits of designating critical habitat, providing these values gives an indication of the value of conserving coral habitat. There is the potential for education and awareness benefits arising from the critical habitat designation, stemming from entities that engage in section 7 consultations, and from members of the general public interested in coral conservation. Entities that engage in section 7 consultations may alter their activities to benefit the species or essential feature because they were made aware of the critical habitat designation through either the section 7 consultation process or the original listings. Members of the public may engage in similar efforts because they learned of the critical habitat designation through outreach materials (NMFS, 2023). Impacts may also occur to governmental or private entities that are E:\FR\FM\30NOP2.SGM 30NOP2 83660 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules implementing existing management plans that provide benefits to the listed species, although such potential impacts would be limited to actions that have a Federal nexus and affect critical habitat. There are a large number of Federal marine protected areas in American Samoa, Guam, CNMI, PRIA, and NWHI where coral critical habitat is being proposed, and many of these jurisdictions have draft or proposed management plans (NMFS, 2023). Impacts of critical habitat designation on the agencies responsible for natural resource management planning of these areas (e.g., the National Park Service, USFWS, and Territorial natural resources management agencies), depend on the type and number of section 7 consultations that may result from the designation in the areas covered by those plans, as well as any potential project modifications recommended by these consultations. Negative impacts to these entities could result if the critical habitat designation interferes with these agencies’ ability to provide for the conservation of the species, or otherwise hampers the management of these areas. Existing or proposed management plans in the marine protected areas and their associated regulations protect existing coral reef resources, but they may not specifically protect the substrate and water quality components of the essential feature for purposes of increasing listed coral abundance and eventual recovery. However, section 7 consultations on the implementation of these Federal marine protected area plans over the next 10 years are not expected to result in incremental project modifications, thus any section 7 impacts will likely be limited to administrative costs (NMFS, 2023, appendix C). Conclusions for Section 4(b)(2) We are not exercising our discretion to exclude any areas from the proposed coral critical habitat based on economic or national security impacts. As summarized in the 4(b)(2) Economic Impact Analysis section, the economic impacts of the proposed coral critical habitat are likely to be low, even on the islands with concentrated economic activity (Tutuila, Guam, Saipan). Since these are the three units where most future proposed Federal actions that could affect critical habitat are expected (NMFS, 2023, appendix C), the conservation benefits of critical habitat are the greatest in these three units. Thus, economic impacts do not outweigh conservation benefits. Likewise, as summarized in the 4(b)(2) National Security Impact Analysis section, the national security impacts of the proposed coral critical habitat on the one requested exclusion site, the Navy’s Ritidian Point Surface Danger Zone complex in Guam, are not expected to outweigh the conservation benefits of designating critical habitat. Proposed Critical Habitat Designations We are proposing to designate critical habitat for 5 listed coral species around 16 islands in 5 U.S. Pacific Islands jurisdictions. For A. globiceps, specific areas around all 16 islands are proposed, including 4 in American Samoa, 1 in Guam, 9 in CNMI, 3 in PRIA, and 1 in Hawaii. The depth ranges of the specific areas for A. globiceps are 0–20 m (3 islands), 0–12 m (9 islands), and 0–10 m (4 islands). For A. retusa, specific areas around three islands are proposed, all of which are in American Samoa. The depth ranges of the specific areas for A. retusa are 0–20 m on all three islands. For A. speciosa and E. paradivisa, specific areas around Tutuila and its offshore banks in American Samoa are proposed. The depth ranges of the specific areas for A. speciosa and E. paradivisa are 20–50 m. For I. crateriformis, specific areas around three islands are proposed, all of which are in American Samoa. The depth ranges of the specific areas for I. crateriformis are 0–20 m on all three islands (table 4). The 4(a)(3)(B)(i) INRMP analyses found that the entire areas around FDM and Wake Atoll, several areas off of Guam, and most of Tinian are ineligible for proposed coral critical habitat. Maps of the proposed critical habitat for each of the listed species around each of the 16 islands are provided at the end of this rulemaking (table 4).

Effects of Critical Habitat Designations Section 7(a)(2) of the ESA requires Federal agencies, including NMFS, to ensure that any action authorized, funded, or carried out by the agency does not jeopardize the continued A. speciosa Depth existence of any threatened or endangered species or destroy or adversely modify designated critical habitat. When a species is listed or critical habitat is designated, Federal agencies must consult with NMFS on any agency actions to be conducted in PO 00000 Frm 00018 Fmt 4701 Sfmt 4702 an area where the species is present and that may affect the species or its critical habitat. During formal consultation, NMFS would evaluate the agency’s action to determine whether the action may adversely affect listed species or designated critical habitat and issue its E:\FR\FM\30NOP2.SGM 30NOP2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS2 findings in a biological opinion. If NMFS concludes in the biological opinion that the proposed agency action would likely result in the destruction or adverse modification of designated critical habitat, NMFS would identify any reasonable and prudent alternatives to the action. Reasonable and prudent alternatives are defined in 50 CFR 402.02 as alternative actions identified during formal consultation that can be implemented in a manner consistent with the intended purpose of the action, that are consistent with the scope of the Federal agency’s legal authority and jurisdiction, that are economically and technologically feasible, and that would avoid the likelihood of jeopardizing the continued existence of listed species or resulting in the destruction or adverse modification of critical habitat. If NMFS concludes in the biological opinion that the proposed agency action would not likely result in the destruction or adverse modification of designated critical habitat, NMFS may provide discretionary conservation recommendations. Regulations at 50 CFR 402.16 require Federal agencies that have retained discretionary involvement or control over an action, or where such discretionary involvement or control is authorized by law, to reinitiate consultation on previously reviewed actions in instances in which (1) critical habitat is subsequently designated, or (2) new information or changes to the action may result in effects to critical habitat not previously considered in the biological opinion. Consequently, some Federal agencies may request reinitiation of consultation or to conference with NMFS on actions for which formal consultation has been completed, if those actions may adversely modify or destroy designated critical habitat or adversely modify or destroy proposed critical habitat, respectively. Activities That May Be Affected Section 4(b)(8) of the ESA requires that we describe briefly, and evaluate in any proposed or final regulation to designate critical habitat, those activities that may adversely modify such habitat or that may be affected by such designation. A wide variety of Federal activities may require ESA section 7 consultation because they may affect the essential feature of critical habitat (i.e., suitable substrate and suitable water quality). Specific future activities would need to be evaluated with respect to their potential to destroy or adversely modify critical habitat, in addition to their potential to affect and jeopardize the continued existence of VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 listed species. For example, activities may adversely modify the essential feature by removing or altering the substrate or reducing water clarity through turbidity. These activities would require ESA section 7 consultation when they are authorized, funded, or carried out by a Federal agency. Non-Federal entities may also be affected by these proposed critical habitat designations if they are undertaking a project that requires a Federal permit or receives Federal funding. Categories of activities that may be affected by the designations include in-water and coastal construction, dredging and disposal, water quality and discharges, fishery management, military activities, shipwreck and marine debris removal, scientific research and monitoring, aquaculture, protected area management, and beach nourishment/ shoreline protection. Further information is provided in the Economic Impact Analysis in our Information Report (NMFS, 2023, appendix C). Questions regarding whether specific activities will constitute destruction or adverse modification of critical habitat should be directed to us (see ADDRESSES and FOR FURTHER INFORMATION CONTACT).

L. 106–554). On December 16, 2004, OMB issued its Final Information Quality Bulletin for Peer Review (Bulletin). The Bulletin was published in the Federal Register on January 14, 2005 (70 FR 2664), and went into effect on June 16, 2005. The primary purpose of the Bulletin is to improve the quality and credibility of scientific information disseminated by the Federal Government by requiring peer review of ‘‘influential scientific information’’ and ‘‘highly influential scientific information’’ prior to public dissemination. ‘‘Influential scientific information’’ is defined as information the agency reasonably can determine will have or does have a clear and substantial impact on important public policies or private sector decisions. The Bulletin provides agencies broad discretion in determining the appropriate process and level of peer review. Stricter standards were established for the peer review of highly influential scientific assessments, defined as information whose dissemination could have a potential impact of more than $500 million in any one year on either the public or private sector or that the dissemination is novel, controversial, or precedent-setting, or has significant interagency interest. The information in the Critical Habitat Information Report (NMFS, 2023) and its appendices was E:\FR\FM\30NOP2.SGM 30NOP2 83662 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules considered influential scientific information and subject to peer review. To satisfy our requirements under the OMB Bulletin, we obtained independent peer review of the the Critical Habitat Information Report (NMFS, 2023) and its appendices. The resulting Peer Review Reports are available on our website https://www.noaa.gov/ information-technology/endangeredspecies-act-critical-habitat-designationfor-7-indo-pacific-corals-informationreport. Classification Takings (Executive Order 12630) Under E.O. 12630, Federal agencies must consider the effects of their actions on constitutionally protected private property rights and avoid unnecessary takings of private property. A taking of property includes actions that result in physical invasion or occupancy of private property and regulations imposed on private property that substantially affect its value or use. In accordance with E.O. 12630, this proposed rule would not have significant takings implications, because it does not include, occupy or invade private property or otherwise affect the value or use of private property to qualify as a taking. A takings implication assessment is not required. khammond on DSKJM1Z7X2PROD with PROPOSALS2 Regulatory Planning and Review (E.O.s 12866, 14094, 13563) This rulemaking has been determined to be significant for purposes of E.O. 12866 as amended by Executive Order 14094. Executive Order 14094, which amends E.O. 12866 and reaffirms the principles of E.O. 12866 and E.O 13563, states that regulatory analysis should facilitate agency efforts to develop regulations that serve the public interest, advance statutory objectives, and be consistent with E.O. 12866, E.O. 13563, and the Presidential Memorandum of January 20, 2021 (Modernizing Regulatory Review). Regulatory analysis, as practicable and appropriate, shall recognize distributive impacts and equity, to the extent permitted by law. E.O. 13563 emphasizes further that regulations must be based on the best available science and that the rulemaking process must allow for public participation and an open exchange of ideas. We have developed this proposed rule in a manner consistent with these requirements. A draft economic impact analysis report, which has been prepared as part of the Information Report (see appendix C of NMFS, 2023), considers the economic costs and benefits of this VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 proposed critical habitat designation and alternatives to this rulemaking as required under E.O. 12866. Based on the impact analysis report, low-end total incremental costs over the 10-year period are estimated at $373,171 for all jurisdictions combined or $53,131 annualized. These are 100 percent administrative costs since the low-end scenario assumes that no project modifications will be required. For the high-end, total incremental costs over the 10-year period are estimated at $6,815,860 for all jurisdictions combined or $970,425 annualized. Of these costs, 95 percent are derived from project modifications since the high-end scenario assumes that 100 percent of section 7 consultations will be formal. The jurisdiction with the highest economic impacts in both scenarios is Guam, due to the relatively high number of expected consultations there (NMFS, 2023, appendix C). As explained under the 4(b)(2) Economic Impact Analysis, we find that the actual economic impacts are likely to be much closer to the low-end scenario’s projections than the high-end scenario’s projections. In addition, economic benefits would be relatively high in the high-end scenario (because project modifications would provide better protection of coral reef ecosystems, which produce economic benefits), but non-existent in the lowend scenario (because there would be no project modifications, and thus no increased protection of coral reef ecosystems). We conclude that the economic impacts of the proposed coral critical habitat are likely to be much closer to those projected by the low-end scenario than the high-end scenario, and also that there would be low economic benefits. That is, we find that the economic analysis and IRFA support the conclusion that the proposed coral critical habitat would have low economic effects on small entities. A proposed Economic Impact Analysis Report (appendix C of the Information Report; NMFS, 2023) and Final ESA section 4(b)(2) Report (i.e., the 4(b)(2) section of the Information Report; NMFS, 2023) have been prepared to support the exclusion process under section 4(b)(2) of the ESA and our consideration of alternatives to this rulemaking. These supporting documents are available at the link provided in ADDRESSES, or upon request (see FOR FURTHER INFORMATION CONTACT). Federalism (E.O. 13132) The E.O. on Federalism, Executive Order 13132, requires agencies to take into account any federalism impacts of regulations under development. It PO 00000 Frm 00020 Fmt 4701 Sfmt 4702 includes specific consultation directives for situations in which a regulation may preempt State law or impose substantial direct compliance costs on State and local governments (unless required by statute). Pursuant to E.O. 13132, we determined that this proposed rule does not have significant federalism effects and that a federalism assessment is not required. In keeping with Department of Commerce policies and consistent with ESA regulations at 50 CFR 424.16(c)(1)(ii), we requested information for this rulemaking from the appropriate marine resources agencies in American Samoa, Guam, CNMI, PRIA, and Hawaii. The designation may have some benefit to State and local resource agencies in that the rule more clearly defines the physical and biological feature essential to the conservation of the species and the areas in which that feature is found. While this designation would not alter where and what non-federally sponsored activities may occur, it may assist local governments in long-range planning (rather than waiting for caseby-case ESA section 7 consultations to occur). Where State and local governments require approval or authorization from a Federal agency for actions that may affect critical habitat, consultation under section 7(a)(2) would be required. While non-Federal entities that receive Federal funding, assistance, or permits, or that otherwise require approval or authorization from a Federal agency for an action, may be indirectly impacted by the designation of critical habitat, the legally binding duty to avoid destruction or adverse modification of critical habitat rests only on the Federal agency. Energy Supply, Distribution, and Use (E.O. 13211) Executive Order 13211 requires agencies to prepare Statements of Energy Effects when undertaking an action expected to lead to the promulgation of a final rule or regulation that is a significant regulatory action under E.O. 12866 and is likely to have a significant adverse effect on the supply, distribution, or use of energy. OMB Guidance on Implementing E.O. 13211 (July 13, 2001) states that significant adverse effects could include any of the following outcomes compared to a world without the regulatory action under consideration: (1) reductions in crude oil supply in excess of 10,000 barrels per day; (2) reductions in fuel production in excess of 4,000 barrels per day; (3) reductions in coal production in excess of 5 million tons (4.5 million metric tons) per year; E:\FR\FM\30NOP2.SGM 30NOP2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS2 (4) reductions in natural gas production in excess of 25 million cubic feet (708,000 cubic meters) per year; (5) reductions in electricity production in excess of 1 billion kilowatt-hours per year or in excess of 500 megawatts of installed capacity; (6) increases in energy use required by the regulatory action that exceed any of the thresholds previously described; (7) increases in the cost of energy production in excess of 1 percent; (8) increases in the cost of energy distribution in excess of 1 percent; or (9) other similarly adverse outcomes. A regulatory action could also have significant adverse effects if it (1) adversely affects in a material way the productivity, competition, or prices in the energy sector; (2) adversely affects in a material way productivity, competition, or prices within a region; (3) creates a serious inconsistency or otherwise interferes with an action taken or planned by another agency regarding energy; or (4) raises novel legal or policy issues adversely affecting the supply, distribution or use of energy arising out of legal mandates, the President’s priorities, or the principles set forth in E.O. 12866 and 13211. The economic impacts of this rulemaking are analyzed in the full 4(b)(2) Economic Impact Analysis, which is appendix C of the Information Report (NMFS, 2023). Based on the results of that analysis, the economic impacts on energy supply, distribution, and use would either be non-existent or far below the above thresholds. Thus, we have determined that this rulemaking will not have a significant adverse effect on the supply, distribution, or use of energy. Therefore, we have not prepared a Statement of Energy Effects. Regulatory Flexibility Act (5 U.S.C. 601 et seq.) We prepared an Initial Regulatory Flexibility Analysis (IRFA) pursuant to section 603 of the Regulatory Flexibility Act (RFA). The IRFA analyzes the impacts to small entities that may be affected by the proposed designation and is included as appendix D of the Information Report (NMFS, 2023), which is available at the link provided in ADDRESSES, or upon request (see FOR FURTHER INFORMATION CONTACT). We welcome public comment on the IRFA, which is summarized below, as required by section 603 of the RFA. The IRFA uses the best available information to identify the potential impacts of designating critical habitat on small entities. However, uncertainty regarding the extent to which impacts of the proposed designation would be allocated between large and small VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 entities complicates quantification of impacts specifically borne by small entities. Absent specific knowledge regarding which small entities may be involved in consultations with NMFS over the next ten years, this analysis relies on industry- and location-specific information on small businesses with North American Classification System (NAICS) codes that were identified as relevant to the major activity categories considered in the economic analysis and which operate within counties or territories that share a coastline with the proposed critical habitat. Activities considered in the draft economic report and the IRFA include in-water and coastal construction, dredging and disposal, water quality and discharges, fishery management, military activities, shipwreck and marine debris removal, scientific research and monitoring, aquaculture, protected area management, and beach nourishment/ shoreline protection. Information presented in section 4.0 of the Economic Impact Analysis Report demonstrates the lack of third-party involvement in consultations on the effects of Federal fishery management, protected area management, shipwreck removal, scientific research and monitoring, and military activities on ESA-listed marine species within the island units considered for proposed coral critical habitat in the five jurisdictions. Unlike consultations on in-water and coastal construction and dredging projects, these consultations are conducted directly between NMFS and the Federal action agency with no third-party involvement. Each of these five categories of consultation is represented in the consultations completed in 2005–2020 that were reviewed for the economic impact analysis, and third parties were not involved in any of them. As discussed in the IRFA and section 6 Economic Impact Analysis Report, consultations on water quality management include inter-agency consultations on regional water quality standards, which do not involve third parties, and projectspecific consultations regarding point source water pollution, such as National Pollutant Discharge Elimination System (NPDES) permits issued to third parties in American Samoa, Guam, and CNMI. The third parties issued NPDES permits are either businesses or territorial or commonwealth governments that do not qualify as small entities. In addition, because no section 7 consultations on beach nourishment and shoreline protection projects occurred within the historical time frame selected for the economic impact analysis, no section 7 PO 00000 Frm 00021 Fmt 4701 Sfmt 4702 83663 consultations on such projects were projected over the next ten years. As a result, no incremental costs are assigned to small entities for these activities. While consultations on aquaculture projects have the potential to involve third parties, the potential economic impacts to third parties are considered de minimis. Moreover, all of the historical aquaculture projects that resulted in consultations considered in the economic impact analysis were sponsored by public entities, none of which qualify as small entities. Consultations on in-water and coastal construction and dredging and disposal (as determined by the 4(b)(2) Economic Impact Analysis Report, which is appendix C of the Information Report (NMFS, 2023)), all have the potential to involve third parties, such as recipients of Clean Water Act section 404 permits. These activities were combined into one broad industry category that may experience impacts to small entities: InWater and Coastal Construction and Dredging. NAICS industries that are relevant to in-water and coastal construction and dredging activities include: • Water and Sewer Line and Related Structures Construction (NAICS 237110). • Highway, Street, and Bridge Construction (NAICS 237310). • Other Heavy and Civil Engineering Construction (237990). • Dredging and Surface Cleanup (NAICS 237990). The IRFA relies on the estimated incremental impacts resulting from the proposed critical habitat designation, as described in section 6.0 of the Economic Impact Analysis Report. To be consistent with this analysis, the IRFA provides low-end and high-end estimates of the impacts to small entities. The IRFA estimates the impacts of the proposed coral critical habitat in terms of the percentage of revenues per small entity, which ranged from 0.20 percent under the low-end (IRFA, table 1) to 36.9 percent under the high-end (IRFA, table 2). These impacts are anticipated to be borne by the small entities engaged in in-water and coastal construction and dredging that consult with NMFS regarding the listed IndoPacific coral species critical habitat in the next 10 years. Impacts are presented in the IRFA for each of the three U.S. Pacific jurisdictional areas where one or more of the listed coral species occur and where small businesses engaged in the relevant activities have been identified—American Samoa, Guam, and CNMI. According to section 6.0 of the Economic Impact Analysis Report, two or fewer consultations on in-water E:\FR\FM\30NOP2.SGM 30NOP2 khammond on DSKJM1Z7X2PROD with PROPOSALS2 83664 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules and coastal construction projects are forecasted to occur in both the NWHI and the PRIA. However, because no businesses are located in either the NWHI or the PRIA, it is not possible to determine what small entities, if any, would be affected. In any case, given that few consultations are expected to occur and that these consultations are likely to be informal, the potential costs to small entities associated with inwater and coastal construction projects in the NWHI and the PRIA are anticipated to be negligible. The low-end estimate assumes no incremental project modifications occur because baseline permit conditions/ regulations would provide sufficient protection to avoid adverse modification of critical habitat. Impacts to small entities are thus assumed to be due solely to the additional administrative costs of considering the potential for adverse effects to critical habitat during section 7 consultations. In addition, the low-end estimate assumes that trends in the frequency of informal consultations over the next 10 years will resemble those of the past 10 years (section 6.0 of the Economic Impact Analysis Report). The low-end estimate of total annualized impacts to small entities is $4,675 (IRFA, table 1). The high-end estimate of the impacts to small entities assumes that all future projects related to in-water and coastal construction and dredging will require formal consultations and that there will be incremental project modification costs for all these future projects (section 6.0 of the Economic Impact Analysis Report). In order to present a conservative estimate of the impacts to small entities (i.e., an estimate more likely to overstate impacts than understate them), the IRFA assumes that all project modification costs are borne by third parties. The high-end estimate of total annualized impacts to small entities is $872,331 (IRFA, table 1). Given the uncertainty regarding which small entities in a given industry will need to consult with NMFS, this analysis estimates impacts to small entities under two different scenarios for both the low-end and high-end estimates. These scenarios are intended to reflect the range of uncertainty regarding the number of small entities that may be affected by the designation and the potential impacts of critical habitat designation on their annual revenues. Under Scenario 1, the IRFA assumes that all third parties involved in future consultations are small entities and that incremental impacts for each territory or commonwealth (American Samoa, Guam, and CNMI) are distributed evenly VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 across all of the entities in the respective territory or commonwealth. Scenario 1 accordingly reflects a high estimate of the number of potentially affected small entities (14 for both the low-end and high-end estimates) and a low estimate of the potential effect in terms of percent of revenue, except for American Samoa, where it is estimated that only one entity is conducting construction activities in the areas considered for critical habitat. The assumption under Scenario 1 is that 14 small entities will be involved in consultation annually reflects the forecast that approximately 14 consultations will occur annually on construction activities involving third parties. This assumes that each consultation on construction activities involves a unique small entity, including 1 small entity in American Samoa, 10 small entities in Guam, and 3 small entities in CNMI. For the lowend estimate, this analysis anticipates that approximately 14 small entities will incur $4,675 in annualized costs under Scenario 1, including $1,244 in costs to the America Samoa-based small entity, $281 in costs per Guam-based small entity, and $235 in costs per CNMIbased small entity. Annualized impacts of the rulemaking are estimated to make up less than 1 percent of average annual revenues of approximately $2.36 million for each affected small entity.1 For the high-end estimate, this analysis anticipates that 14 small entities will incur $872,331 in annualized costs under Scenario 1, including $254,356 in costs to the America Samoa-based small entity, $48,953 in costs per Guam-based small entity, and $47,751 in costs per CNMI-based small entity. Annualized impacts of the rulemaking are estimated to make up 17.0 percent of average annual revenues of $1.5 million for the American Samoa-based entity, 2.1 percent of average annual revenues of approximately $2.37 million for Guambased small entities, and 1.9 percent of average annual revenues of $2.47 million for CNMI-based small entities. Under Scenario 2, this analysis assumes that all third parties participating in future consultations are small and that costs associated with each consultation action are borne each year by a single small entity within the potentially impacted construction industries. This method likely understates the number of small entities affected and overstates the likely impacts on the impacted small entity. For the low-end estimate, this analysis 1 Average annual revenues were calculated based on company-specific revenue data sourced from the Dun & Bradstreet Hoovers database. PO 00000 Frm 00022 Fmt 4701 Sfmt 4702 anticipates that a single small entity will bear $4,675 in annualized costs. These annualized impacts make up less than 1 percent of estimated average annual revenues of $2.36 million for the impacted small entity. For the high-end estimate, this analysis anticipates that a single small entity will bear $872,331 in annualized costs. These impacts represent approximately 37 percent of estimated average annual revenues for the impacted small entity. As explained under 4(b)(2) Economic Impact Analysis, we conclude that the actual economic impacts are likely to be much closer to the low-end scenario’s projections than the high-end scenario’s projections. In addition, economic benefits would be relatively high in the high-end scenario (because project modifications would provide better protection of coral reef ecosystems, which produce economic benefits), but non-existent in the low-end scenario (because there would be no project modifications, and thus no increased protection of coral reef ecosystems). Moreover, while Scenario 1 and Scenario 2 present a range of potentially affected entities and the associated revenue effects, we expect the actual number of small entities affected and revenue effects will be somewhere in the middle. In other words, some subset of the small entities in American Samoa, Guam, and CNMI greater than 2 and up to 14 will participate in section 7 consultations on Indo-Pacific coral critical habitat and bear associated impacts annually. We conclude that the economic impacts of the proposed coral critical habitat are likely to be much closer to those projected by the low-end scenario than the high-end scenario, and also that there would be low economic benefits. That is, we find that the economic analysis and IRFA support the conclusion that the proposed coral critical habitat would have low economic effects on small entities. There are no record-keeping requirements associated with the rulemaking. Similarly, there are no reporting requirements. No Federal laws or regulations duplicate or conflict with this proposed rule. However, the protection of listed species and habitat under critical habitat may overlap other sections of the ESA. For instance, listing of the threatened Indo-Pacific corals under the ESA already requires Federal agencies to consult with NMFS to avoid jeopardy to the species. However, this analysis only examines the incremental impacts to small entities from the proposed critical habitat rule. The RFA requires consideration of alternatives to the proposed rule that E:\FR\FM\30NOP2.SGM 30NOP2 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules would minimize significant economic impacts to small entities. We considered the following alternatives when developing the proposed critical habitat rule. khammond on DSKJM1Z7X2PROD with PROPOSALS2 Alternative 1: No Action Alternative Under the no action alternative, we would not designate critical habitat for the listed corals. The alternative of not designating critical habitat was considered in this IRFA but rejected because, in this case, it would violate the legal requirements of the ESA. Moreover, we have determined that the physical feature forming the basis for critical habitat designation is essential to the corals’ conservation, and conservation for these species will not succeed without this feature being available. Thus, the lack of protection of the critical habitat feature from adverse modification could result in continued declines in abundance of the listed corals, and loss of associated economic and other values these corals provide to society, such as recreational and commercial fishing and diving services, and shoreline protection services. Small entities engaged in some coral reefdependent industries would be adversely affected by the continued declines in the listed corals. Thus, the no action alternative is not necessarily a ‘‘no cost’’ alternative for small entities. Alternative 2: Preferred Alternative Under this alternative, the areas designated are waters ranging from 0 to 10 m deep to 0 to 50 m deep in the 15 units located in American Samoa, Guam, CNMI, the NWHI, and the PRIA. As noted in the Critical Habitat Information Report, the following areas are ineligible for proposed critical habitat: parts of Guam, parts of Tinian all of Farallon de Medinilla, and all of Wake Atoll. An analysis of the costs and benefits of the preferred alternative designation is presented in appendix C of the Information Report. Relative to the no action alternative, this alternative will likely involve an increase in administrative and project modification costs for those section 7 consultations required to avoid adverse impacts to critical habitat, above and beyond those required due to the corals’ listing alone. We have determined that no categories of activities would require consultation, and no categories of project modifications would be required, in the future solely due to this rulemaking and the need to prevent adverse modification of critical habitat. Similarly, all categories of activities have similar potential to adversely impact corals and critical habitat, and the same project modifications would VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 remedy both sets of adverse effects. However, in some areas of proposed coral critical habitat, there may be locations with no colonies of listed corals, especially after a natural disturbance event (e.g., coral bleaching or crown-of-thorns starfish outbreak). For future Federal actions that have small action areas within such locations, costs to small entities could occur, and would represent an incremental impact of this rulemaking. On the other hand, because projects with larger or more diffuse action areas are more likely to impact both the listed corals and their critical habitat, consultation and project modification costs associated with those projects would more likely be coextensive with the coral listings or another regulatory requirement. The preferred alternative was selected because it best implements the critical habitat provisions of the ESA by including the well-defined environmental features essential to the species’ conservation, and due to the important conservation benefits that will result from this alternative relative to the no action alternative. Alternative 3: Designating a Subset of Areas A third alternative was considered that would have excluded from designation those areas in which, on economic or national security bases, the benefits of exclusion outweigh the benefits of inclusion. No areas, other than those excluded in the Preferred Alternative on the basis of national security impacts, were identified where it was determined that the benefits of exclusion outweigh the conservation value of designation to the species. In addition, the public did not submit comments on the benefits of exclusion and inclusion in general, nor were comments submitted on those benefits as they relate to specific areas. Thus, we rejected this alternative because it would lessen the conservation value to the species. Coastal Zone Management Act (16 U.S.C. 1451 et seq.) Under section 307(c)(1)(A) of the Coastal Zone Management Act (CZMA) and its implementing regulations (15 CFR part 923), each Federal activity within or near coastal zones that has reasonably foreseeable effects on any land or water use or natural resource of the coastal zone shall be carried out in a manner which is consistent to the maximum extent practicable with the enforceable policies of approved State coastal management programs. Upon publication of the proposed rule (85 FR 76262, November 27, 2020), we PO 00000 Frm 00023 Fmt 4701 Sfmt 4702 83665 determined that the proposed designation of critical habitat for the listed corals would have no reasonably foreseeable effects on the enforceable policies of Guam’s, CNMI’s, and American Samoa’s approved Coastal Zone Management Programs, and submitted our determinations to each of the responsible Territorial agencies. CNMI and Guam formally objected to our determinations on February 12, 2021, and March 26, 2021, respectively. Both Territories stated that there were reasonably foreseeable coastal effects of coral critical habitat for several reasons, including administrative burdens, economic impacts, and third-party impacts. CNMI requested a consistency determination and identified specific enforceable policies to be addressed. Guam interpreted our determination as a consistency determination, and requested a new consistency determination that addressed specific enforceable policies. In response to these objections and concerns expressed informally by American Samoa, we held a meeting with the three Territorial CZM Programs (American Samoa, Guam, and CNMI) on July 27, 2021. We explained the basis for our determinations at the July meeting and scheduled follow-up meetings with representatives of CNMI and Guam CZM Programs to review their objections in detail. On September 2, 2021, and September 7, 2021, we held meetings with CNMI’s and Guam’s CZM Programs, respectively, and the NOAA Office of Coastal Management, to review the Territories’ objections to our determinations. The Territories explained why they find that coral critical habitat, as proposed in 2020, would result in administrative burdens, economic impacts, and third-party impacts. The Territorial representatives stated that they believe incomplete biological and economic data were used in the 2020 proposed rule, resulting in the habitat needs of the listed corals being overstated, and the extent of economic impacts of critical habitat being understated in the proposed rule. Subsequently, the Territories requested that NMFS work with their experts to obtain more thorough and recent biological and economic data to inform the proposed coral critical habitat rule. On September 30, 2021, and October 28, 2021, NMFS held meetings with biologists based in American Samoa, CNMI, Guam, and Honolulu to review records of listed corals in the Territories, which contributed to the development of appendix A in the Information Report (NMFS, 2023). On September 23, 2021, and September 25, E:\FR\FM\30NOP2.SGM 30NOP2 83666 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules 2021, Guam and CNMI submitted letters to NMFS with updated economic data, which was used in section 5.1.7 of the Information Report (NMFS, 2023). In making revisions to the 2020 proposed critical habitat, in addition to considering other public comments received, we considered the comments submitted by each of the Territories regarding their respective concerns about the proposed critical habitat. With the withdrawal of the 2020 proposed rule, we also withdraw the November 27, 2020, CZMA determinations for the American Samoa, Guam, and CNMI CZM Programs. Consistent with the CZMA, we will determine how to proceed for the critical habitat now being proposed and coordinate accordingly with the responsible agencies in American Samoa, Guam, CNMI, and Hawaii. Paperwork Reduction Act (44 U.S.C. 3501 et seq.) This proposed rule does not contain any new or revised collection of information, defined by the Paperwork Reduction Act of 1995. Notwithstanding any other provision of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the PRA, unless that collection of information displays a currently valid OMB Control Number. Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.) This proposed rule will not produce a Federal mandate. The designation of critical habitat does not impose a legally-binding duty on non-Federal government entities or private parties. The only regulatory effect is that Federal agencies must ensure that their actions do not destroy or adversely modify critical habitat under section 7 of the ESA. Non-Federal entities that receive Federal funding, assistance, permits, or otherwise require approval or authorization from a Federal agency for an action may be indirectly affected by the designation of critical habitat, but the Federal agency has the legally binding duty to avoid destruction or adverse modification of critical habitat. We do not anticipate that this proposed rule will significantly or uniquely affect small governments. Therefore, a Small Government Action Plan is not required. Consultation and Coordination With Indian Tribal Governments (E.O. 13175) The longstanding and distinctive relationship between the Federal and tribal governments is defined by treaties, statutes, Executive orders, judicial decisions, and agreements, which differentiate tribal governments from the other entities that deal with, or are affected by, the Federal Government. This relationship has given rise to a special Federal trust responsibility involving the legal responsibilities and obligations of the United States towards Indian Tribes and with respect to Indian lands, tribal trust resources, and the exercise of tribal rights. Pursuant to these authorities, lands have been retained by Indian Tribes or have been set aside for tribal use. These lands are managed by Indian Tribes in accordance with tribal goals and objectives within the framework of applicable treaties and laws. Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, outlines the responsibilities of the Federal Government in matters affecting tribal interests. The proposed critical habitat designations for threatened Indo-Pacific corals are located in U.S. Pacific Islands and therefore do not have tribal implications in accordance with Executive Order 13175. Environmental Justice and Racial Equity (E.O.s 12898, 14096, 14019, 13985) The designation of critical habitat is not expected to have a disproportionately high effect on minority populations or low-income populations. The purpose of this rulemaking is to protect and conserve ESA-listed species through the designation of critical habitat and is expected to help promote a healthy environment; thus, we do not anticipate minority populations or low-income populations to experience disproportionate and adverse human health or environmental burdens. The designation of critical habitat is not expected to disproportionately affect minority populations, low-income populations, or populations otherwise adversely affected by persistent poverty or inequality. Further, it is not expected to create any barriers to opportunity for underserved communities.

For the reasons set out in the preamble, we propose to amend 50 CFR parts 223 and 226 as follows: PART 223—THREATENED MARINE AND ANADROMOUS SPECIES 1. The authority citation for part 223 continues to read as follows: ■ Authority: 16 U.S.C. 1531 1543; subpart B, § 223.201–202 also issued under 16 U.S.C. 1361 et seq.; 16 U.S.C. 5503(d) for § 223.206(d)(9). 2. In § 223.102(e), in the table, under the heading ‘‘Corals’’ revise the entries for ‘‘Acropora globiceps,’’ ‘‘Acropora retusa,’’ ‘‘Acropora speciosa,’’ ‘‘Euphyllia paradivisa,’’ and ‘‘Isopora crateriformis’’ to read as follows: ■ § 223.102 Enumeration of threatened marine and anadromous species. * * * (e) * * * * * Species 1 khammond on DSKJM1Z7X2PROD with PROPOSALS2 Common name * Description of listed entity Scientific name * * * Citation(s) for listing determination(s) * Critical habitat * ESA rules * Corals Coral, [no common name] ............

PART 226—DESIGNATED CRITICAL HABITAT 3. The authority citation for part 226 continues to read as follows: ■ Critical habitat is designated in the following jurisdictions for the following species as depicted in the maps below and described in paragraphs (a) through (e) of this section. The maps can be viewed or obtained with greater resolution (available at https:// Authority: 16 U.S.C. 1533. ■ 4. Add § 226.231 to read as follows: www.fisheries.noaa.gov/action/ proposed-rule-designate-critical-habitatthreatened-indo-pacific-corals) to enable a more precise inspection of the proposed critical habitat for A. globiceps, A. retusa, A. speciosa, E. paradivisa, and I. crateriformis. (a) Critical habitat locations. Critical habitat is designated for the following species in the following jurisdictions: TABLE 1 TO PARAGRAPH (a) Species State—counties (or other jurisdiction) Acropora globiceps ...... American Samoa (AS), Guam (Gu), Commonwealth of the Northern Mariana Islands (CNMI), Pacific Remote Island Areas (PRIA), Hawaii (HI). AS, PRIA. AS. AS. AS. khammond on DSKJM1Z7X2PROD with PROPOSALS2 Acropora retusa ............ Acropora speciosa ....... Euphyllia paradivisa ..... Isopora crateriformis .... (b) Critical habitat boundaries. Except as noted in paragraph (d) of this section, critical habitat for the five species includes all specific areas depicted in the maps below. (c) Essential feature. The feature essential to the conservation of A. globiceps, A. retusa, A. speciosa, E. paradivisa and I. crateriformis is: Sites that support the normal function of all life stages of the corals, including reproduction, recruitment, and maturation. These sites are natural, consolidated hard substrate or dead coral skeleton, which is free of algae and sediment at the appropriate scale at the point of larval settlement or fragment reattachment, and the associated water column. Several attributes of these sites determine the quality of the area and influence the value of the associated feature to the conservation of the species: (1) Substrate with presence of crevices and holes that provide cryptic habitat, the presence of microbial biofilms, or presence of crustose coralline algae; (2) Reefscape with no more than a thin veneer of sediment and low VerDate Sep<11>2014 17:41 Nov 29, 2023 Jkt 262001 occupancy by fleshy and turf macroalgae; (3) Marine water with levels of temperature, aragonite saturation, nutrients, and water clarity that have been observed to support any demographic function; and (4) Marine water with levels of anthropogenically-introduced (from humans) chemical contaminants that do not preclude or inhibit any demographic function. (d) Areas not included in critical habitat. Critical habitat does not include the following particular areas where they overlap with the areas described in paragraphs (a) through (c) of this section: (1) Pursuant to ESA section 4(a)(3)(B)(i), all areas subject to the 2017 Wake Island and 2019 Joint Region Marianas Integrated Natural Resources Management Plans; (2) Managed areas that do not provide the quality of substrate essential for the conservation of the five Indo-Pacific corals are defined as particular areas whose consistently disturbed nature renders them poor habitat for coral growth and survival over time. These PO 00000 Frm 00025 Fmt 4701 Sfmt 4702 managed areas include specific areas where the substrate has been disturbed by planned management authorized by local, territorial, State, or Federal governmental entities at the time of critical habitat designation, and will continue to be periodically disturbed by such management. Examples include, but are not necessarily limited to, dredged navigation channels, shipping basins, vessel berths, and active anchorages. A comprehensive list of managed areas is provided in appendix B of the Information Report (NMFS, 2023); (3) Existing artificial substrates including but not limited to: fixed and floating structures, such as aids-tonavigation (AToNs), seawalls, wharves, boat ramps, fishpond walls, pipes, submarine cables, wrecks, mooring balls, docks, aquaculture cages. A comprehensive list of artificial substrates is provided in appendix B of the Information Report (NMFS, 2023). (e) Critical habitat maps. The specific areas of critical habitat within the 16 island units for the 5 listed coral species are shown on the following 24 maps. These black and white maps are based E:\FR\FM\30NOP2.SGM 30NOP2 83668 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules on the maps in the Information Report (NMFS, 2023) that are color-coded for the listed coral species.

Endangered and Threatened Species; Designation of Critical 
Habitat for Five Species of Threatened Indo-Pacific Corals

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Proposed rule; withdrawal and reproposal; request for comments.

-----------------------------------------------------------------------

SUMMARY: On November 27, 2020, we, NMFS, published in the Federal 
Register a proposal to designate 17 island units of critical habitat in 
the Pacific Islands Region for 7 Indo-Pacific coral species listed 
under the Endangered Species Act (ESA). Based on public comments and 
new information regarding the interpretation of the records of the 
listed corals and application to critical habitat, a substantial 
revision of the proposed rule is warranted. Accordingly, we are 
withdrawing the 2020 proposed rule and publishing this new proposed 
rule. We propose to designate critical habitat for five of the seven 
coral species that were addressed in the 2020 proposed rule: Acropora 
globiceps, Acropora retusa, Acropora speciosa, Euphyllia paradivisa, 
and Isopora crateriformis. Proposed critical habitat includes 16 island 
units encompassing approximately 251 square kilometers ((km\2\); 97 
square miles (mi\2\)) of marine habitat. Several areas are ineligible 
for critical habitat because of final Department of Defense Integrated 
Natural Resource Management Plans that we have determined will benefit 
the listed corals. We have considered economic, national security, and 
other relevant impacts of the proposed designations, but are not 
proposing to exclude any areas from the critical habitat designations 
due to anticipated impacts.

DATES: Comments on this proposal must be received by February 28, 2024.
    Public hearings: Public hearings on this proposed rule will be held 
during the public comment period at dates, times and locations to be 
announced in a forthcoming Federal Register Notice.

SUPPLEMENTARY INFORMATION:

Background

    We listed 20 reef coral species as threatened under the ESA on 
September 10, 2014 (79 FR 53851), 15 of which occur in the Indo-
Pacific. The remaining five species occur in the Caribbean. On November 
27, 2020, we proposed critical habitat for the seven listed Indo-
Pacific species that were then considered to occur within U.S. 
jurisdiction (85 FR 76262) and the five listed Caribbean species (85 FR 
76302). All 20 of these listed coral species have undergone some level 
of population decline and are susceptible to multiple threats, 
including ocean warming, diseases, ocean acidification, ecological 
effects of fishing, and land-based sources of pollution. We determined 
that these species are likely to become endangered throughout their 
ranges within the foreseeable future as a result of a combination of 
threats, the most severe of which are related to climate change.
    On November 27, 2020, NMFS proposed to designate critical habitat 
for the seven listed Indo-Pacific corals that were then considered to 
occur within U.S. jurisdiction (Acropora globiceps, Acropora 
jacquelineae, Acropora retusa, Acropora speciosa, Euphyllia paradivisa, 
Isopora crateriformis, and Seriatopora aculeata) and opened a public 
comment period (85 FR 76262). In response to multiple requests from the 
public, the initial 60-day public comment period was extended three 
times, with the last extension ending on May 26, 2021. Two virtual 
public hearings were held in January 2021. Approximately 80 public 
comments were received on the proposed rule.
    The coral critical habitat proposed for designation in 2020 (the 
``2020 proposed rule'') consisted of substrate and water column habitat 
characteristics essential for the reproduction, recruitment, growth, 
and maturation of the seven listed coral species. A total of 17 areas 
or ``units'' were proposed to be designated as critical habitat, 
including 4 units in American Samoa (Tutuila and Offshore Banks, Ofu-
Olosega, Ta'u, Rose Atoll), 1 unit in Guam, 7 units in the Commonwealth 
of the Northern Mariana Islands (CNMI; Rota, Aguijan, Tinian, Saipan, 
Anatahan, Pagan, Maug), and 5 units in the Pacific Remote Islands Areas 
(PRIA; Howland, Palmyra Atoll, Kingman Reef, Johnston Atoll, Jarvis). 
Based on the best available information at that time, between 1 and 6 
listed coral species were thought to occur within each of these 17 
units. Several other areas were also found to be either ineligible for 
designation as critical habitat, or were proposed to be excluded from 
the designation due to national security impacts. These areas included 
the following: A complex of overlapping Navy Surface Danger Zones off 
of Ritidian Point in Guam, other parts of Guam, parts of Tinian in 
CNMI, a group of six Navy anchorage berths on Garapan Bank in Saipan in 
CNMI, all of Farallon de Medinilla in CNMI, and all of Wake Atoll in 
PRIA.
    The ESA defines critical habitat under section 3(5)(A) as the (1) 
specific areas within the geographical area occupied by the species at 
the time it is listed, on which are found those physical or biological 
features essential to the conservation of the species and which may 
require special management considerations or protection; and (2) 
specific areas outside the geographical area occupied by the species at 
the time it is listed, upon a determination by the Secretary of 
Commerce (Secretary) that such areas are essential for the conservation 
of the species (16 U.S.C. 1532(5)(A)). Conservation is defined in

[[Page 83645]]

section 3(3) of the ESA as to use, and the use of, all methods and 
procedures which are necessary to bring any endangered species or 
threatened species to the point at which the measures provided pursuant 
to this Act are no longer necessary (16 U.S.C. 1532(3)). Section 
3(5)(C) of the ESA provides that, except in those circumstances 
determined by the Secretary, critical habitat shall not include the 
entire geographical area which can be occupied by the threatened or 
endangered species. ESA implementing regulations provide that critical 
habitat shall not be designated within foreign countries or in other 
areas outside U.S. jurisdiction (50 CFR 424.12(g)).
    Section 4(a)(3)(B)(i) of the ESA prohibits designating as critical 
habitat any lands or other geographical areas owned or controlled by 
the Department of Defense (DOD) or designated for its use, that are 
subject to an Integrated Natural Resources Management Plan (INRMP) 
prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if the 
Secretary determines in writing that such plan provides a benefit to 
the species for which critical habitat is designated. Section 4(b)(2) 
of the ESA requires us to designate critical habitat for threatened and 
endangered species on the basis of the best scientific data available 
and after taking into consideration the economic, national security, 
and any other relevant impact, of specifying any particular area as 
critical habitat. Pursuant to this section, the Secretary may exclude 
any area from critical habitat if she determines the benefits of such 
exclusion outweigh the benefits of specifying such area as part of the 
critical habitat. However, the Secretary cannot exclude areas if 
failure to designate them as critical habitat will result in the 
extinction of the species (16 U.S.C. 1533(b)(2)).
    Once critical habitat is designated, section 7(a)(2) of the ESA 
requires Federal agencies to ensure that actions they fund, authorize, 
or carry out are not likely to destroy or adversely modify that habitat 
(16 U.S.C. 1536(a)(2)). This requirement is in addition to the section 
7(a)(2) requirement that Federal agencies ensure their actions are not 
likely to jeopardize the continued existence of ESA-listed species. 
Specifying the geographic location of critical habitat also facilitates 
implementation of section 7(a)(1) of the ESA by identifying areas where 
Federal agencies can focus their conservation programs and use their 
authorities to further the purposes of the ESA. Critical habitat 
requirements do not apply to citizens engaged in actions on private 
land that do not involve a Federal agency. The requirements of section 
7(a)(2) to not destroy or adversely modify critical habitat apply only 
to Federal agencies and do not apply to non-Federal entities on non-
Federal land or within non-Federal waters in the absence of a Federal 
nexus (e.g. Federal funding, Federal permit). However, designating 
critical habitat can help focus the efforts of other conservation 
partners (e.g., state and local governments, individuals, and non-
governmental organizations).
    On July 5, 2022, the U.S. District Court for the Northern District 
of California issued an order vacating the ESA section 4 implementing 
regulations that were revised or added to 50 CFR part 424 in 2019 
(``2019 regulations,'' see 84 FR 45020, August 27, 2019) without making 
a finding on the merits. On September 21, 2022, the U.S. Court of 
Appeals for the Ninth Circuit granted a temporary stay of the district 
court's July 5 order (Wash. Cattlemen's Ass'n, No. 22-70194, 2022 WL 
4393033). On November 14, 2022, the Northern District of California 
issued an order granting the government's request for voluntary remand 
without vacating the 2019 regulations. The District Court issued a 
slightly amended order two days later on November 16, 2022 (Ctr. for 
Biological Diversity v. Haaland, No. 19-cv-05206-JST, 2022 WL 
19975245). As a result, the 2019 regulations remain in effect, and we 
are applying the 2019 regulations here. We also note that, on June 22, 
2023, our agency in coordination with the Department of Interior 
jointly published proposed revisions to the ESA section 4 regulations 
(88 FR 40764). For purposes of this determination and in an abundance 
of caution, we considered whether the analysis or its conclusions would 
be any different under the current, pre-2019, and recently proposed 
regulations. We have determined that while the analysis differs in some 
ways, the conclusions presented here would not be any different. We 
will consider any changes to the section 4 regulations, as appropriate, 
should they be finalized and become effective prior to completion of a 
final critical habitat determination.
    In this rulemaking, the terms ``occupied area,'' ``specific area,'' 
and ``critical habitat unit'' each have distinct meanings. The terms 
``occupied area'' and ``specific area'' are species-specific, whereas 
the term ``critical habitat unit'' is not species-specific. The term 
``occupied area'' is consistent with the definition of the 
``geographical area occupied by the species'' in 50 CFR 424.02 and 
refers to the area that may generally be delineated around species' 
occurrences at the time of listing, as determined by the Secretary--
i.e., range. Within each occupied area, ``specific areas'' are the 
areas containing the essential feature of critical habitat for the 
species. We use the term ``critical habitat unit'' to refer to the 
cumulative specific areas for one or more species around the 16 islands 
proposed for designation. Critical habitat units are named according to 
the particular island or offshore bank around, or on which, the coral 
habitat is located. For example, overlapping occupied areas for five 
listed coral species occur around Tutuila Island and its offshore 
banks, which is thus named the Tutuila and Offshore Banks Unit of coral 
critical habitat.

Rationale for Withdrawing 2020 Proposed Rule

    We evaluated the comments and information received during the 
public comment period and at the public hearings that were held for the 
2020 proposed rule, as well as other new information that has become 
available, as described in the Critical Habitat Information Report for 
this proposed rule (NMFS, 2023) and its appendices. Based on our 
consideration of the comments and information, a substantial revision 
of the 2020 proposed rule is needed for three main reasons:
    1. The initial methodology used to compile existing records of 
listed coral species in U.S. waters was not exhaustive, resulting in 
the inadvertent exclusion of some islands within the occupied area for 
some listed species that should have been included as occupied areas.
    2. The initial methodology used to determine which U.S. islands 
were within the occupied area for each listed coral species at the time 
of listing (2014) was too simplistic, resulting in the inadvertent 
inclusion of some islands in the occupied area for some listed species 
that should not have been included.
    3. The initial methodology used to determine the depth range of 
each listed species on each island within its occupied area used 
incorrect assumptions, resulting in inaccurate depth ranges for some 
species in some locations (i.e., some depth ranges were larger than 
they should have been).
    With regard to the compilation of records of listed coral species 
in U.S. waters, in developing the 2020 proposed rule, we relied on 
Federal coral reef monitoring programs as the only source of records 
used for most of the remote

[[Page 83646]]

islands. However, as pointed out in the public comments and also as 
indicated by new information, other records exist for some islands. 
Specifically, several sources of photo records and expert data records 
have been published or shared since the 2020 proposed rule published, 
and some previously unused historical photo records were found to have 
been mislabeled with the names of unlisted species. As a result, 
numerous existing records that were not considered in the 2020 proposed 
rule, including some that provide the only records of any listed coral 
species on some islands, were considered in developing this proposed 
rule.
    With regard to determining the occupied area within U.S. 
jurisdiction for each listed coral species for the 2020 proposed rule, 
we assumed that any expert record of a listed coral species was 
adequate to conclude that the island was within the occupied area for 
that species at the time of listing. However, as pointed out in the 
public comments and also as indicated by new information, for those 
islands with very few records for a listed coral species, such records 
may not provide adequate evidence that the island was within the 
occupied area of the listed species at the time of listing. There are 
several potential reasons for this, including species 
misidentifications, old records of species that were no longer present 
at the time of listing, and the likelihood that a single record of a 
colony of a listed species represents a vagrant individual. For 
example, only a single colony of the listed coral Acropora jacquelineae 
has ever been recorded in U.S. waters on Tutuila, an island that has 
been frequently surveyed by coral experts since that single colony was 
recorded in 2008, and that record was used as the basis for including 
A. jacquelineae in the 2020 proposed rule. However, as indicated in the 
public comments and by new information, that record likely represents a 
vagrant individual of A. jacquelineae, and thus Tutuila should not be 
considered as being occupied by the species at the time of listing. 
Therefore, the mere existence of an expert record of a listed coral 
from an island is not necessarily adequate to support a conclusion that 
the area was within the occupied area of the species at the time of 
listing.
    With regard to the species' depth ranges applied in the 2020 
proposed rule, we assumed that the depth range of a listed coral 
species shown by the records from an extensively surveyed island was 
similarly representative of that species' depth range on other islands. 
For example, since the records of A. globiceps from Tutuila showed a 
depth range of 0-20 m on that island, we assumed that the species' 
depth range was 0-20 m in other locations where we lacked depth 
distribution data, including islands within (e.g., Rose Atoll) and 
outside (e.g., Guam) the Samoan Archipelago. However, as indicated in 
the public comments and by new information, the depth range of a listed 
coral species can vary from island to island, especially between 
archipelagos. For example, surveys that became available or were 
conducted since the 2020 proposed rule between 10 and 20 m on both 
Tutuila and Guam indicate that A. globiceps is commonly found to 20 m 
on Tutuila in the Samoan Islands but only to 12 m on Guam in the 
Mariana Islands.
    In order to address these issues with the 2020 proposed rule, a 
systematic methodology was developed and implemented for compilation, 
assessment, and interpretation of the records of each listed coral 
species in order to determine its occupied area within U.S. waters at 
the time of listing in 2014 (i.e., which islands) as well as the depth 
range of each species on each of those islands. This new methodology 
resulted in significant changes to the occupied area (i.e., which 
islands are included or not), as well as depth ranges of critical 
habitat for most listed coral species. Ultimately, these changes 
altered which species are considered to occupy areas within U.S. 
jurisdiction and the location and boundaries of the areas proposed for 
designation. Specifically, two species included in the 2020 proposed 
rule, Acropora jacquelineae and Seriatopora aculeata, are no longer 
considered to have occupied areas within U.S. jurisdiction at the time 
of listing, and we cannot designate critical habitat in areas outside 
U.S. jurisdictions (50 CFR 424.12(g)). In addition, some new areas are 
being proposed that were not included in the 2020 proposed rule 
(Alamagan and Uracas in CNMI, French Frigate Shoals in Hawaii). Given 
these multiple, substantial changes, we concluded it was necessary to 
withdraw the 2020 proposed rule and publish this proposed rule to 
provide the public an opportunity to comment on the new methodology and 
the different areas being proposed as critical habitat.

New Methodology for Determining Occupied Areas and Depth Ranges

    The determinations of the occupied areas and depth ranges that 
inform critical habitat are based on the records of each listed coral 
species within U.S. waters. However, using the records for critical 
habitat requires overcoming three major challenges: (1) Finding all the 
records (compilation); (2) accounting for the high variability in the 
quality, quantity, age, species identification uncertainty, survey 
effort, and other factors associated with the records (assessment); and 
(3) interpreting the records to determine which islands are within the 
occupied area for each listed species and thus should be included in 
critical habitat (application). In order to address these challenges 
and ensure that coral critical habitat is based on the best available 
information, we conducted exhaustive searches to compile all the 
available records for each listed coral species around each island 
within U.S. Pacific Islands jurisdictions, and developed a consistent 
and transparent methodology for assessing and applying the records. The 
results are provided in appendix A of the Information Report (NMFS, 
2023), hereafter referred to as the Records Document, and provide the 
foundation for this new proposed rule. The compilation, assessment, and 
application of the records are summarized from the Records Document 
below.

Compilation of Records

    We compiled the available records for each listed coral species 
around each island within U.S. Pacific Islands waters via the following 
steps: (1) Reviewed all relevant NOAA Fisheries files, such as those 
used for the final coral listing rule and 2020 proposed critical 
habitat; (2) gathered records from government agencies that have 
conducted coral reef monitoring within these areas; (3) gathered 
records from other sources such as research projects, site surveys, 
area inventories, etc.; (4) conducted an exhaustive virtual search; and 
(5) consulted with experts from the Territorial Governments (American 
Samoa, Guam, CNMI) and the Marine National Monuments (Rose Atoll, 
Pacific Remote Islands, Marianas Trench) to ensure that no records were 
overlooked. Some of these records were brought to our attention by the 
public comments that we received during the public comment period in 
2021. The search produced records of seven listed coral species (A. 
globiceps, A. jacquelineae, A. retusa, A. speciosa, E. paradivisa, I. 
crateriformis, and S. aculeata) from U.S. Pacific Islands waters (NMFS, 
2023, appendix A). This comprehensive compilation process yielded more 
than twice as many records as were used for the 2020 proposed rule, 
including historical records that we were unaware of in 2020 as well as 
new data collected since then.
    The records were divided into 45 records groups by island and 
species.

[[Page 83647]]

Throughout this proposed rule and in the supporting documents, we refer 
to high islands (volcanic, e.g., Guam), atolls (e.g., Rose Atoll), 
stand-alone reefs (e.g., Kingman Reef), shoals (e.g., French Frigate 
Shoals (FFS)), and pinnacles (e.g., Gardner Pinnacles) as ``islands.'' 
The 45 records groups included a total of 24 such islands, 4 of which 
were in American Samoa (Tutuila and Offshore Banks, Ofu-Olosega, Ta'u, 
Rose Atoll), 1 in Guam (Guam), 9 in CNMI (Rota, Aguijan, Tinian, 
Saipan, Farallon de Medinilla (FDM), Alamagan, Pagan, Maug Islands, 
Uracas), 7 in PRIA (Howland, Baker, Palmyra Atoll, Kingman Reef, 
Johnston Atoll, Wake Atoll, Jarvis), and 3 in the Northwestern Hawaiian 
Islands (FFS, Maro Reef, Gardner Pinnacles) in Hawaii, as shown in 
table 2 of appendix A. We found no records of any listed species in any 
of the Main Hawaiian Islands (NMFS, 2023, appendix A).

Assessment of Records

    We assessed each of the 45 records groups (i.e., all records of a 
listed species from an island) in terms of the multiple factors, 
including (1) quality of records, (2) quantity of records, (3) age of 
records, (4) species identification uncertainty, and (5) survey effort. 
We addressed the quality of records by organizing the records into 
three mutually-exclusive categories: ``photo records,'' ``expert data 
records,'' or ``other records.'' Because of species identification 
uncertainty, photo records are ideal, as long as the location and date 
of the photo are known, and the photo clearly shows colony and branch 
morphology. However, many records of coral species are in the form of 
data sheets or species lists, and lack photos. Any such record 
collected by a recognized Indo-Pacific reef-building coral species 
expert is considered an expert data record. Records that do not meet 
the criteria for photo records or expert data records are considered 
other records (e.g., personal communications). We confirmed all records 
via direct communication with the experts who took the records, or with 
experts who were able to vouch for the records. Our determinations of 
whether the island was within the occupied area for a listed species at 
the time of listing relied almost entirely upon photo records and 
expert data records. However, other records provided valuable 
information for some islands or parts thereof. For example, records 
that do not meet the criteria for photo or expert data records (i.e., 
exact dates and locations not available) provide information on depth 
and habitat distributions (NMFS, 2023, appendix A).
    Although we did not specify a particular quantity of records 
necessary to support a determination that a particular island was 
within the occupied area for a listed species at the time of listing, 
the more photo records and expert data records we have for a species 
from an island, the greater the likelihood that the island was within 
the occupied area for a listed species at the time of listing. Islands 
with a single photo record or expert data record of a listed species 
may or may not have been within the occupied area of that species at 
the time of listing (2014), depending on other factors (NMFS, 2023, 
appendix A).
    Older records are not necessarily lower quality, thus age of 
records was not a consideration for determining the quality of a 
record. However, the more that a record predates listing, the less 
relevance it had to our determination of whether the island was within 
the occupied area for a listed species at the time of listing (NMFS, 
2023, appendix A).
    Species identification uncertainty is substantial for most of the 
15 listed Indo-Pacific reef coral species, even for experts. For listed 
coral species that are consistently distinct from similar species and 
frequently observed, species identification uncertainty has decreased 
since listing, as survey effort and expertise have increased. This is 
the case with A. globiceps and I. crateriformis. In addition, E. 
paradivisa and S. aculeata are consistently distinct from similar 
species, although they are very infrequently observed within U.S. 
waters. For these four listed species, identification uncertainty is 
relatively low at this point in time for coral species experts based in 
the U.S. Pacific Islands. In contrast, for listed species that are very 
similar to other species, the increase in survey effort since listing 
in 2014 has emphasized the difficulty in distinguishing them. This is 
the case with A. retusa, especially in the Marianas and PRIA. The 
combination of high colony morphological variability and low numbers of 
records from the Marianas (i.e., Guam and CNMI) and PRIA is such that 
we have low confidence in these records, even though they are expert 
data records. Even more challenging are those listed species that are 
very similar to other species but are very infrequently observed, such 
as A. jacquelineae and A. speciosa. For these three listed species, 
identification uncertainty is relatively high at this point in time, 
even for coral species experts who focus on the U.S. Pacific Islands 
(NMFS, 2023, appendix A).
    A particular species identification uncertainty problem is the 
apparent variability in colony morphology of A. retusa and related 
species between the American Samoa, Guam-CNMI, and PRIA archipelagos. 
The combination of high colony morphological variability and low 
numbers of records in Guam-CNMI and PRIA is such that we have low 
confidence in these records, even though they are expert data records. 
However, in American Samoa, there is apparently lower colony 
morphological variability and higher numbers of records for A. retusa, 
thus we have high confidence in these records.
    Survey effort refers to the amount of expert coral species surveys 
that have been conducted on an island. Historical survey effort has 
been highly variable from island to island, potentially influencing the 
interpretation of the records. However, all islands in this document 
except FDM in CNMI have been included in the Pacific Islands Fisheries 
Science Center's (PIFSC) species-level standardized coral reef 
monitoring surveys at least one time since listing in 2014, and some 
islands have also been included in standardized surveys by other 
agencies. PIFSC's surveys are quite extensive around each island, 
including a large number of transects and covering wide depth ranges 
(appendix A). The Department of the Navy (DON) restricts access to FDM, 
hence PIFSC does not survey there. However, the Navy periodically 
conducts species-level coral surveys at FDM by recognized Indo-Pacific 
reef-building coral species experts, thus numerous surveys have been 
conducted on FDM both around and since the time of listing. All islands 
have been subject to extensive species-level surveys (i.e., the PIFSC 
and DON surveys) around or since the time of listing, including within 
the depth ranges and habitat types of all listed coral species (NMFS, 
2023, appendix A).
    Several other factors were taken into consideration in assessing 
the records, including taxonomic issues, morphological variability 
across archipelagos, and habitat preferences. Taxonomic issues include 
confusion of A. globiceps with A. humilis, and the name change from 
Acropora crateriformis to Isopora crateriformis, both of which affected 
how we treated historical records. Finally, some types of coral reef 
habitats are surveyed more than others, mainly because of accessibility 
and safety. Of the surveys that produced the records in this document, 
the majority took place on forereefs (AKA reef slopes) between about 5 
and 20 m of depth, and some surveys included reef slopes of 20-30 m

[[Page 83648]]

depth. Fewer surveys were done in backreef habitats, such as pools, 
lagoons, and reef flats, raising the possibility that the records may 
not be representative of species' distributions across habitats. 
However, for some of the more frequently surveyed islands, habitat-
specific information is available, as noted in the species-island 
sections (NMFS, 2023, appendix A).
    Based on the assessment factors, we developed a 10-category system 
for rating the level of evidence provided by each records group (i.e., 
all records of a listed species from an island) that the island was 
within the occupied area for the listed species at the time of listing 
in 2014, from the least to the most evidence (table 1). Then we 
interpreted the rating results of each records group to determine 
whether the island was within the occupied area for the listed species 
at the time of listing, and thus should be included in critical 
habitat. For islands within the occupied area of a listed species, we 
also used the records to determine the depth range of that species on 
the island.

    We interpreted the ratings of the records groups in terms of the 
likelihood that the island was within the occupied area for the listed 
species at the time of listing in 2014. We considered record groups 
with ratings of 1-3 as providing inadequate evidence that the island 
was within the occupied area for the listed species at the time of 
listing. Eighteen of the 45 records groups were rated as 1-3 (table 1). 
The rationales for why these records groups provide inadequate evidence 
for the species being within the occupied area at the time of listing 
are summarized below from the Records Document (NMFS, 2023, appendix 
A).
    One A. jacquelineae records group was rated as 1 (Tutuila), a 
species with high species identification uncertainty even for trained 
experts. This record consists of photos of a single colony of A. 
jacquelineae on Tutuila taken in 2008. Since then, hundreds of expert 
surveys have been conducted on Tutuila within the habitat and depth 
range of the species, including at the location of the original record, 
but no other records have been documented. The regulatory definition of 
an occupied area does not include habitats used solely by vagrant 
individuals (i.e., waifs). Waifs are a single individual or small group 
of individuals found outside of its normal range, presumably advected 
by unusual currents or weather conditions (Johnson et al., 2000), which 
are common among reef corals (Turak and DeVantier, 2019). Based on the 
fact that no other colonies of A. jacquelineae have been observed 
before or since 2008 on Tutuila despite extensive expert surveys, there 
is considerable likelihood that the single observed colony of A. 
jacquelineae on Tutuila was a waif colony. Since occupied areas do not 
include habitats used solely by vagrant individuals (i.e., waifs), this 
record provides inadequate evidence that Tutuila was within the 
occupied area of A. jacquelineae at the time of listing in 2014 (NMFS, 
2023, appendix A).
    Seven A. retusa records groups were rated as 1 (Ta'u, Guam, Rota, 
Tinian, Howland, Kingman Reef, Johnston Atoll), a species with high 
species identification uncertainty even for trained experts. All seven 
records groups consist of one or two records collected at least several 
years before listing (2004--2010). Five of the records groups each 
consist of one or two photo records that all appear to be of closely-
related but undescribed species. The other two records groups (Ta'u, 
Rota) each consist of a single expert data record but because of 
species identification uncertainty and lack of photos, identifications 
could not be confirmed. Because these records groups each consist of 
only one or two ambiguous records collected at least several years 
before listing, and expert surveys of all seven islands since listing 
have not recorded any A. retusa

[[Page 83649]]

colonies, these records groups provide inadequate evidence that any of 
the seven islands were within the occupied area of A. retusa at the 
time of listing in 2014 (NMFS, 2023, appendix A).
    Two A. speciosa records groups were rated as 1 (Guam, Kingman 
Reef), a species with high species identification uncertainty even for 
trained experts. The Guam records group consists of several photos of a 
single colony in Apra Harbor of Guam taken in 2010. Definitive species 
identification requires examination of a skeletal sample, but no sample 
was taken. Many subsequent expert dives and surveys were conducted in 
the area in the following years, but neither the original colony nor 
any other colonies resembling A. speciosa were recorded. The Kingman 
Reef records group consists of a single expert data record collected 
between 2004 and 2006 with no photos or skeletal sample. Because these 
records groups each consist of only a single ambiguous colony recorded 
at least several years before listing, and expert surveys of both 
islands since listing have not recorded any A. speciosa colonies, these 
records groups provide inadequate evidence that either island was 
within the occupied area of A. speciosa at the time of listing in 2014 
(NMFS, 2023, appendix A).
    Five A. globiceps records were groups rated as 2 (Howland, Baker, 
Kingman Reef, Maro Reef, Gardner Pinnacles), a species with low species 
identification uncertainty for trained experts. All five records groups 
consist of one or two photo records collected at least several years 
before listing (2000-2006). The three records groups from PRIA 
(Howland, Baker, Kingman Reef) each consist of one or two photo records 
taken between 2004 and 2006 and identified by an expert at that time 
but that are clearly not A. globiceps, and thus provide no evidence 
that these three islands were within the occupied area of A. globiceps 
at the time of listing in 2014. The two records groups from NWHI (Maro 
Reef, Gardner Pinnacles) are a photo of a single colony from 2004 (Maro 
Reef) and photos of a group of colonies in close proximity from 2000 
(Gardner Pinnacles). Because these records groups each consist of only 
a single colony or group of colonies (i.e., likely clones) collected 
many years before listing, multiple expert surveys conducted at Maro 
Reef and Gardner Pinnacles through 2008 did not record any A. globiceps 
colonies, and an expert survey of both islands since listing did not 
record any A. globiceps colonies, these records groups provide 
inadequate evidence that either island was within the occupied area of 
A. globiceps at the time of listing in 2014 (NMFS, 2023, appendix A).
    Two S. aculeata records groups were rated as 2 (Guam, Saipan), a 
species with low species identification uncertainty for trained 
experts. The Guam records group consists of three photo records (two 
from the 1970s and one from 2010), while the Saipan records group 
consists of an expert data record of a cluster of colonies in close 
proximity (i.e., likely clones) from 2011. Since 2010 and 2011, 
hundreds of expert surveys have been conducted on Guam and Saipan 
within the habitat and depth range of S. aculeata, but no additional 
records have been documented. Since the most recent of these records 
were collected in 2010 (Guam) and 2011 (Saipan), there have been sharp 
declines in coral cover throughout Guam and Saipan, especially of 
branching corals such as S. aculeata, due to a multitude of 
disturbances. There are several reasons why these records groups 
provide inadequate evidence that either island was within the occupied 
area of S. aculeata at the time the species was listed in 2014. First, 
each records group consists of only a few records collected between the 
1980s and 2010. Second, hundreds of expert surveys have been conducted 
on Guam and Saipan since listing in 2014 but did not record any 
additional S. aculeata colonies. Third, there have been sharp declines 
in the coral cover of branching corals such as S. aculeata on Guam and 
Saipan that started at least several years before listing in 2014 
(NMFS, 2023, appendix A).
    One A. retusa records group was rated as 3 (Jarvis), a species with 
high species identification uncertainty even for trained experts. This 
records group consists of a single photo taken in 2018 although the 
photo does not clearly show branch and colony morphology. Like the 
other A. retusa photo records from PRIA, the colony could only be 
identified as possible A. retusa colonies because of a combination of 
species identification uncertainty and taxonomic ambiguity. Because A. 
retusa has high species identification uncertainty especially in PRIA, 
the records group consists of only one poor quality and ambiguous photo 
record, and post-listing standardized monitoring surveys in 2015 and 
2018 at Jarvis did not detect any A. retusa colonies, this records 
group does not provide adequate evidence that Jarvis was within the 
occupied area of A. retusa at the time of listing in 2014 (NMFS, 2023, 
appendix A).
    We considered record groups with ratings of 4-10 to provide 
adequate evidence that the island was within the occupied area for the 
listed species at the time of listing. Twenty-seven of the 45 records 
groups were rated as 4-10 (table 1), and the rationales for why these 
records groups provide adequate evidence for the species being within 
the occupied area at the time of listing are summarized below from the 
Records Document (NMFS, 2023, appendix A).
    Two A. globiceps records groups were rated as 4 (Alamagan, Uracas), 
a species with low species identification uncertainty for trained 
experts. These records groups consist of one (Alamagan) and two 
(Uracas) photo records, all taken in 2017. No expert surveys have been 
conducted on either island since then, except PIFSC's standardized 
monitoring survey in 2022, details for which are not yet available. 
Because A. globiceps has low species identification uncertainty, and 
these records consist of photo records taken in 2017, these records 
groups provide adequate evidence that the two islands were within the 
occupied area of A. globiceps at the time of listing in 2014 (NMFS, 
2023, appendix A).
    Two records groups were rated as 5, A. retusa from Wake Atoll, and 
A. speciosa from Tutuila. Both species have high species identification 
uncertainty even for trained experts. The A. retusa/Wake records group 
consists of many photo and expert data records since listing in 2014, 
although standardized monitoring surveys have not detected the species 
on Wake. The A. speciosa/Tutuila records group consists of several 
photo and expert data records before and after listing in 2014, 
including two from 2016 that were confirmed with skeletal samples, and 
one record from a standardized monitoring survey that was not confirmed 
with a skeletal sample. Although both species have high species 
identification uncertainty even for trained experts, the A. retusa/Wake 
records group consists of many photo and expert data records since 
listing, and the A. speciosa/Tutuila records group includes multiple 
post-listing records that were confirmed with skeletal samples. Thus 
the records groups provide adequate evidence that Wake Atoll was within 
the occupied area of A. retusa, and that Tutuila was within the 
occupied area of A. speciosa, at the time of listing in 2014 (NMFS, 
2023, appendix A).
    Seven records groups were rated as 6, six for A. globiceps (Ta'u, 
Rose Atoll, FDM, Palmyra Atoll, Johnston Atoll, FFS), and one for E. 
paradivisa from Tutuila. Both species have low species identification 
uncertainty for trained experts. Each of the seven records

[[Page 83650]]

groups include several records collected before and after listing in 
2014. Because both species have low species identification uncertainty, 
multiple records are available for all seven islands, and records were 
collected after listing, these records groups provide adequate evidence 
that the six islands were within the occupied area of A. globiceps, and 
that Tutuila was within the occupied area of E. paradivisa, at the time 
of listing in 2014 (NMFS, 2023, appendix A).
    One A. retusa records group was rated as 7 (Ofu-Olosega), a species 
with high species identification uncertainty even for trained experts. 
This records group consists of several records collected before and 
after listing in 2014. Although A. retusa generally has high species 
identification uncertainty, colonies of the species have a typical and 
distinct appearance in American Samoa. Because multiple records are 
available, some of which were collected after listing, this records 
group provides adequate evidence that Ofu-Olosega was within the 
occupied area of A. retusa at the time of listing in 2014 (NMFS, 2023, 
appendix A).
    Six records groups were rated as 8, five for A. globiceps (Ofu-
Olosega, Aguihan, Pagan, Maug Islands, Wake Atoll), and one for I. 
crateriformis from Ta'u. Both species have low species identification 
uncertainty for trained experts. Each of the six records groups consist 
of many records collected after listing in 2014. Because both species 
have low species identification uncertainty, and many records are 
available for all six islands since listing, these records groups 
provide adequate evidence that the five islands were within the 
occupied area of A. globiceps, and that Ta'u was within the occupied 
area of I. crateriformis, at the time of listing in 2014 (NMFS, 2023., 
appendix A).
    Two A. retusa records groups were rated as 9 (Tutuila, Rose Atoll), 
a species with high species identification uncertainty even for trained 
experts. These records groups each consist of dozens of records 
collected after listing in 2014. Although A. retusa generally has high 
species identification uncertainty, colonies of the species have a 
typical and distinct appearance in American Samoa. Because dozens of 
records are available from after listing for both islands, these 
records groups provide adequate evidence that Tutuila and Rose Atoll 
were within the occupied area of A. retusa at the time of listing in 
2014 (NMFS, 2023, appendix A).
    Seven records groups were rated as 10, five for A. globiceps 
(Tutuila, Guam, Rota, Tinian, Saipan), and two for I. crateriformis 
(Tutuila, Ofu-Olosega). Both species have low species identification 
uncertainty for trained experts. Each of the seven records groups 
consist of dozens to hundreds of records collected after listing in 
2014. Because both species have low species identification uncertainty, 
and many records are available for all seven islands since listing, 
these records groups provide adequate evidence that the five islands 
were within the occupied area of A. globiceps, and that Tutuila and 
Ofu-Olosega were within the occupied area of I. crateriformis, at the 
time of listing in 2014 (NMFS, 2023, appendix A).

Summary of Results for Occupied Areas and Depth Ranges

    In summary, and based on the new methodology for identifying 
occupied areas and depth ranges as described above and in the Records 
Document (NMFS, 2023, appendix A), 18 records groups each provide 
inadequate evidence that the island where the records were collected 
was within the occupied area of the listed species at the time of 
listing, while 27 records groups each provide adequate evidence that 
the island was within the occupied area of the listed species at the 
time of listing. These 27 records groups were from 18 islands for A. 
globiceps, 4 islands for A. retusa, 1 island each for A. speciosa and 
E. paradivisa, and 3 islands for I. crateriformis (table 2).
    In addition, the 27 records groups were used to determine the depth 
ranges of each listed species around each island. For A. globiceps, the 
depth ranges are 0-20 m (3 islands), 0-12 m (10 islands), and 0-10 m (5 
islands). For the other 4 species, the depth ranges are 0-20 m for A. 
retusa (4 islands) and I. crateriformis (3 islands), and 20-50 m for A. 
speciosa and E. paradivisa (table 2).

Changes From the 2020 Proposed Rule

    Application of the records assessment methodology described above 
led to substantive changes from the 2020 proposed rule: (1) a reduction 
in the number of listed corals whose occupied areas occurred within 
U.S. jurisdiction at the time of listing from seven to five species; 
(2) changes in the numbers of islands included within the occupied 
areas for most of the listed species; and (3) changes in the depth 
ranges for all of the listed species. These substantive changes led to 
other changes in this proposed rule, including refinement of critical 
habitat boundaries, and elimination of all proposed exclusions from 
critical habitat under 4(b)(2). Changes between this and the 2020 
proposed rule are summarized in table 3 and described in further detail 
below.

* These are the listed Indo-Pacific coral species whose occupied areas
  include islands within U.S. jurisdiction. The islands within the
  occupied area for each listed coral species are shown in table 2.
** These are the areas for which coral critical habitat was considered,
  most of which is proposed, for all of the listed coral species
  combined.
*** These are the depth ranges around a given island for all of the
  listed species found on that island. The depth ranges of each listed
  species on each island are shown in table 2.

Changes to the Occupied Areas

    Application of the new methodology for determining the occupied 
area for each listed species (NMFS, 2023, appendix A) resulted in 
changes to the numbers of islands included within the occupied areas at 
the time of listing (2014) for five of the seven listed species in the 
2020 proposed rule. For A. globiceps, some new islands were added while 
some islands that were included in the 2020 proposed rule were removed. 
For A. jacquelineae, A. retusa, A. speciosa, and S. aculeata, some 
islands that were included in the 2020 proposed rule were removed. No 
changes to the islands included within the occupied areas were made for 
E. paradivisa or I. crateriformis.
    For A. globiceps, four islands were added to the occupied area that 
were not in the 2020 proposed rule: Alamagan and Uracas in CNMI, 
Johnston Atoll in PRIA, and French Frigate Shoals in Hawaii. Also, two 
islands from the 2020 proposed rule were removed, Anatahan in CNMI and 
Kingman Reef in PRIA. Since 16 islands were within the occupied area 
for A. globiceps in the 2020 proposed rule, and 4 new islands have been 
added while 2 have been removed, this proposed rule includes 18 islands 
within the occupied area for A. globiceps. These 18 islands are in 5 
jurisdictions, including 4 in American Samoa, 1 in Guam, 9 in CNMI, 3 
in PRIA, and 1 in Hawaii (table 2).
    For A. jacquelineae, one island from the 2020 proposed rule was 
removed, Tutuila and Offshore Banks in American Samoa. Since that was 
the only island within the occupied area for this species, the range of 
A. jacquelineae is considered to be entirely outside of U.S. waters.
    For A. retusa, eight islands from the 2020 proposed rule were 
removed: Ta'u in American Samoa, Guam, Tinian in CNMI, and Howland, 
Kingman Reef, Johnston Atoll, Wake Atoll, and Jarvis in PRIA. Since 11 
islands were within the occupied area for A. retusa in the 2020 
proposed rule, and 8 have been removed, this proposed rule includes 3 
islands within the occupied area for A. retusa, all of which are in 
American Samoa (table 2).
    For A. speciosa, one island from the 2020 proposed rule was 
removed, Kingman Reef in PRIA. Since two islands were within the 
occupied area for A. speciosa in the 2020 proposed rule, and one has 
been removed, this proposed rule includes one island within the 
occupied area for A. speciosa, Tutuila and Offshore Banks in American 
Samoa (table 2).
    For S. aculeata, two islands from the 2020 proposed rule were 
removed: Guam and Saipan in CNMI. Since these were the only islands 
within the occupied area for this species, the range of S. aculeata is 
considered to be entirely outside of U.S. waters.
    In conclusion, based on the results of the new methodology, the 
islands within the occupied areas changed, and therefore the 
geographical areas occupied by five of the seven listed species have 
been revised accordingly from the 2020 proposed rule, including: A. 
jacquelineae, A. globiceps, A. retusa, A. speciosa, and S. aculeata. 
Since the occupied areas for two of the listed species, A. jacquelineae 
and S. aculeata, do not include any areas within U.S. jurisdiction, 
those two species have been removed from this proposed rule. A total of 
18 islands are within the occupied area for at least one listed 
species, including 5 islands with multiple listed species, Tutuila and 
Offshore Banks (5 species), Ofu-Olosega (3 species), and Ta'u, Rose 
Atoll, and Wake Atoll (2 species each). The other 13 islands are within 
the occupied area for A. globiceps only (table 2).

Changes to the Depth Ranges

    The records compiled via the new methodology for determining the 
occupied area for each listed species (NMFS, 2023, appendix A) also 
provided new depth range information for all five listed species in 
this proposed rule. Depth ranges were determined for each listed 
species around each island within its occupied area.

[[Page 83652]]

    For A. globiceps, depth ranges were 0-20 m around all 16 islands 
considered for this species in the 2020 proposed rule. Based on the 
updated records, the depth ranges of A. globiceps around the 18 islands 
within its occupied area are now 0-20 m (3 islands), 0-12 m (10 
islands), and 0-10 m (5 islands) (table 2).
    For A. retusa, depth ranges were 0-10 m around all 11 islands 
considered for this species in the 2020 proposed rule. Based on the 
updated records, the depth ranges of A. retusa around the four islands 
within its occupied area are now 0-20 m (table 2).
    For A. speciosa, depth ranges were 12-40 m around the two islands 
considered for this species in the 2020 proposed rule. Based on the 
updated records, the depth range of A. speciosa around the one island 
within its occupied area is now 20-50 m (table 2).
    For E. paradivisa, depth range was 2-40 m around the one island 
considered for this species in the 2020 proposed rule. Based on the 
updated records, the depth range of E. paradivisa around the one island 
within its occupied area is now 20-50 m (table 2).
    For I. crateriformis, depth ranges were 0-12 m around the three 
islands considered for this species in the 2020 proposed rule. Based on 
the updated records, the depth ranges of I. crateriformis around the 
three islands within its occupied area are now 0-20 m (table 2).

Changes to the Specific Areas

    In this proposed rule, we refined the boundaries of the specific 
areas (i.e., areas containing the essential feature of critical habitat 
for a species) for all species and islands. As a result of additional 
records collected to develop the proposed critical habitat designation, 
we obtained new information on habitat preferences indicating that the 
listed coral species are found entirely or predominantly on certain 
types of hard substrates but not others. We used that new information 
along with benthic maps showing the types of hard substrates throughout 
the occupied areas and depth ranges to delineate the boundaries of the 
specific areas for each of the listed corals. That is, we used detailed 
island-scale benthic habitat maps illustrating the variety of hard 
substrates that occur within the depth ranges of the listed species, 
together with habitat preference information showing that the listed 
species occur entirely or predominantly on certain hard substrate types 
but not on others. Thus, the benthic substrate maps, the habitat 
preferences, and other site-specific sources of substrate and water 
quality information were used to delineate the boundaries of the 
specific areas around each island within the listed species' occupied 
areas and depth ranges, as described further in the Specific Areas 
section.

Changes to Areas Excluded From Designation

    Section 4(b)(2) of the ESA requires that we consider the economic 
impact, impact on national security, and any other relevant impact, of 
designating any particular area as critical habitat. The 4(b)(2) 
analyses in this proposed rule have been updated with new information 
and data on national security and economic impacts. In particular, the 
Navy's exclusion request for six anchorage berths in the Saipan Unit, 
which was granted in the 2020 proposed rule, is now moot because the 
depth range of proposed critical habitat is 0-12 m in this unit instead 
of 0-40 m as in the 2020 proposed rule. That is, the deepest point of 
critical habitat in this proposed rule in the Saipan Unit is shallower 
than the shallowest point within any of these six anchorage berths. One 
national security exclusion request remains in this proposed rule at 
the Navy's Ritidian Point Surface Danger Zone Complex on Guam. A full 
description of the 4(b)(2) analyses is provided in the Application of 
ESA section 4(b)(2) section of this document.

Critical Habitat Identification and Designation

    In the following sections, we describe the relevant definitions and 
requirements in the ESA and our implementing regulations, and the key 
information and criteria used to prepare this proposed critical habitat 
designation for the five listed corals (A. globiceps, A. retusa, A. 
speciosa, E. paradivisa, and I. crateriformis). In accordance with 
section 4(b)(2) of the ESA and our implementing regulations (50 CFR 
424.12), this proposed rule is based on the best scientific information 
available.
    Our five-step process for identifying critical habitat areas for 
the threatened corals was to determine the following: (1) the 
geographical areas occupied by the listed corals at the time of listing 
(i.e., occupied areas, as well as depth ranges for the listed corals 
within the occupied areas); (2) the physical or biological features 
essential to the conservation of the listed corals (i.e., essential 
feature); (3) whether the physical or biological features within these 
geographical areas may require special management considerations or 
protection; (4) the specific areas within each of the occupied areas 
where the essential features occur (this step consists of four sub-
steps); and (5) whether any unoccupied areas are essential to the 
conservation of any of the corals. Our evaluation and determinations 
are described in detail in the Information Report (NMFS, 2023) and are 
summarized below.

Geographical Area Occupied by the Species (Occupied Area)

    The process for determining the occupied areas for the listed 
corals species is described in the preceding sections. The islands 
within the occupied area for each of the five listed species are listed 
in table 2, which include marine habitat around: 18 islands for A. 
globiceps, 4 islands for A. retusa, 3 islands for I. crateriformis, and 
1 island each for A. speciosa and E. paradivisa.
    The occupied area for each listed species is further defined by its 
depth range around each island within its occupied area, also shown in 
table 2. For A. globiceps, the depth ranges are 0-20 m (3 islands), 0-
12 m (10 islands), and 0-10 m (5 islands). For the other 4 species, the 
depth ranges are 0-20 m for A. retusa (4 islands) and I. crateriformis 
(3 islands), and 20-50 m for A. speciosa and E. paradivisa (1 island 
each).
    The occupied areas for the 5 listed species include a total of 18 
islands, 5 of which include overlapping occupied areas for multiple 
listed species (Tutuila and Offshore Banks, Ofu-Olosega, Ta'u, Rose 
Atoll, and Wake Atoll).

Physical or Biological Features Essential for Conservation

    Within the occupied areas, critical habitat consists of specific 
areas in which are found those physical and biological features (PBFs) 
essential to the conservation of the species and that may require 
special management considerations or protection. PBFs essential to the 
conservation of the species are defined as the features that occur in 
specific areas and that are essential to support the life-history needs 
of the species, including water characteristics, soil type, geological 
features, sites, prey, vegetation, symbiotic species, or other 
features. A feature may be a single habitat characteristic, or a more 
complex combination of habitat characteristics. Features may include 
habitat characteristics that support ephemeral or dynamic habitat 
conditions. Features may also be expressed in terms relating to 
principles of conservation biology, such as patch size, distribution 
distances, and connectivity (50 CFR 424.02).

[[Page 83653]]

    Based on the best scientific information available, we identify the 
following physical feature essential to the conservation of the five 
corals.
    Reproductive, recruitment, growth, and maturation habitat. Sites 
that support the normal function of all life stages of the corals, 
including reproduction, recruitment, and maturation. These sites are 
natural, consolidated hard substrate or dead coral skeleton, which is 
free of algae and sediment at the appropriate scale at the point of 
larval settlement or fragment reattachment, and the associated water 
column. Several attributes of these sites determine the quality of the 
area and influence the value of the associated feature to the 
conservation of the species:
    (1) Substrate with presence of crevices and holes that provide 
cryptic habitat, the presence of microbial biofilms, or presence of 
crustose coralline algae;
    (2) Reefscape (all the visible features of an area of reef) with no 
more than a thin veneer of sediment and low occupancy by fleshy and 
turf macroalgae;
    (3) Marine water with levels of temperature, aragonite saturation, 
nutrients, and water clarity that have been observed to support any 
demographic function; and
    (4) Marine water with levels of anthropogenically-introduced (from 
humans) chemical contaminants that do not preclude or inhibit any 
demographic function.
    With regard to the first and second attributes, reef-building 
corals, including the listed species, require exposed natural 
consolidated hard substrate for the settlement and recruitment of 
larvae or asexual fragments. Substrate provides the physical surface 
and space necessary for settlement of coral larvae, a stable 
environment for metamorphosis of the larvae into the primary polyp, 
growth of juvenile and adult colonies, and re-attachment of fragments. 
A number of attributes have been shown to influence coral larval 
settlement. Positive cues include the presence of crustose coralline 
algae, biofilms, and cryptic habitat such as crevices and holes. 
Attributes that negatively affect settlement include presence of 
sediment and algae (NMFS, 2023).
    With regard to the third and fourth attributes, reef-building 
corals, including the listed species, require seawater temperature, 
aragonite saturation, nutrients, and water clarity conditions within 
suitable ranges to enable coral growth, reproduction, and recruitment. 
Corals may tolerate and survive in conditions outside these suitable 
ranges, depending on the local conditions to which they have 
acclimatized and the intensity and duration of deviations outside the 
suitable ranges. Extended deviations from suitable ranges result in 
direct negative effects on all life stages. The listed corals thrive in 
warm, clear, nutrient-poor marine waters with calcium carbonate 
concentrations that allow for symbiont photosynthesis, coral 
physiological processes and skeleton formation. This water must also 
have low to no levels of contaminants that would interfere with normal 
functions of all life stages (NMFS, 2023).
    Some new information relevant to the essential feature was provided 
during the public comment period for the 2020 proposed rule or has 
become available since then, and has been added to the description of 
the essential feature in the Information Report (NMFS, 2023). The new 
information did not, however, result in any changes to the definition 
of the essential feature from the 2020 proposed rule.

Need for Special Management Considerations or Protection

    As described in the Information Report (NMFS, 2023), we determined 
that the essential feature may require special management 
considerations or protection throughout the species' ranges because 
threats to this feature exist within these areas. Such threats include 
global and local threats, especially ocean warming, ocean 
acidification, coral disease, land-based sources of pollution, and 
fishing. There were no public comments on this section of the Draft 
Information Report or 2020 proposed rule, nor has any relevant new 
information become available that would alter our conclusion regarding 
the potential need for special management considerations or protection.

Specific Areas Containing the Essential Feature Within the Geographical 
Areas Occupied by the Species

    As described under Geographical Area Occupied by the Species 
(Occupied Area) and shown in table 2, we identified 18 island units 
that we considered for proposed coral critical habitat. Each island 
unit includes occupied habitat for at least one listed coral species. 
Within each occupied area in each island unit, we delineated more 
specific areas that contain the essential feature using a 4-step 
process: (1) general information was used to delineate soft vs. hard 
substrates; (2) for the hard substrate areas identified in Step 1, 
specific substrate information was used to delineate unsuitable vs. 
suitable hard substrates; (3) for the suitable hard substrate areas 
identified in Step 2, we used water quality information to further 
delineate suitable vs. unsuitable areas; and (4) from the suitable 
areas identified in Steps 1-3, we removed any overlapping artificial 
substrates and managed areas. The 4 steps were implemented for each of 
the 18 units as follows:
    (1) For Step 1, we used comprehensive substrate maps developed by 
PIFSC (PIFSC, 2021) to delineate soft vs. hard substrates, leaving only 
hard substrate areas within the combined depth ranges of all listed 
species in each unit, except for Wake Atoll and FFS, for which PIFSC 
(2021) did not produce maps. For Wake Atoll, we used the substrate map 
from the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) 
(PIBHMC 2021). For French Frigate Shoals, we used the geomorphological 
structure component of the maps developed by National Centers for 
Coastal and Ocean Sciences (NCCOS) (NCCOS, 2003).
    (2) For Step 2, we started with the hard substrate areas identified 
in Step 1, then distinguished unsuitable vs. suitable hard substrates. 
Many hard substrates are unsuitable because: (1) highly-fluctuating 
physical conditions cause frequent and extreme environmental changes 
(e.g., high tide surge vs. low tide sun exposure on many reef flat 
substrates); (2) water motion continuously mobilizes sediment (e.g., 
pavement with sand channels) or unstable substrate (e.g., rubble); or 
(3) flat, low-relief areas provide poor settlement and growth habitat 
(e.g., pavement). Removal of these areas left suitable hard substrates, 
including spur-and-groove, individual patch reef, aggregate reef, 
aggregated patch reef, scattered coral/rock, and rock/boulder. For this 
step, primary information sources were Brainard et al. (2008, 2012, 
2019), NCCOS (2003, 2005, 2010), PIBHMC (2021), PIFSC (2021), the 
detailed public comment letters from the Territories (AS DMWR 2021, 
Guam DOAG 2021, CNMI DLNR 2021), and the American Samoa, Guam, CNMI, 
PRIA, and Northwestern Hawaiian Islands (NWHI) chapters in Waddell and 
Clarke (2008). Additional sources for individual units are cited in the 
unit sections in the Information Report (NMFS, 2023).
    (3) For Step 3, starting with the suitable hard substrate areas 
identified in Step 2, we used water quality information to further 
delineate suitable vs. unsuitable areas. Unsuitable areas are those 
with water quality conditions that chronically fall outside of suitable

[[Page 83654]]

ranges. For example, some of the areas identified in Step 2 are nearly 
constantly exposed to pollution such as excessive nutrients, excessive 
sediment (i.e., more than a thin veneer), or contaminants, making them 
unsuitable. Generally, such areas occur in enclosed lagoons and inner 
harbors where there is high runoff and limited water circulation. 
Outside of such areas, point and non-point sources of pollution 
generally do not overlap with suitable hard substrates because 
wastewater outfalls are located on soft substrates beyond the reef 
slopes, and stormwater and freshwater discharges occur primarily on 
soft substrates (sand or mud) or unsuitable hard substrates (pavement 
or rubble) along or near shorelines. For this step, primary information 
sources were Brainard et al. (2008, 2012, 2019), EPA (2021a-f), the 
detailed public comment letters from the Territories (AS DMWR, 2021, 
Guam DOAG, 2021, CNMI DLNR, 2021), Territory water quality assessments 
(AS EPA, 2020, CNMI BECQ, 2018), and sources for individual units cited 
in the Information Report (NMFS, 2023).
    (4) For Step 4, from the suitable areas identified via the above 
three steps, we removed any artificial substrates and managed areas, 
because they do not provide the essential feature. ``Managed areas,'' 
for the purposes of this proposed rule, are specific areas where the 
substrate has been persistently disturbed by planned management 
authorized by local, state, or Federal governmental entities at the 
time of critical habitat designation, and expectations are that the 
areas will continue to be periodically disturbed by such management. 
Examples include, but are not necessarily limited to, all harbors and 
their entrance channels, navigation channels, turning basins, and 
berthing areas that are periodically dredged or maintained. This only 
applies to existing artificial substrates and managed areas, not 
proposed or planned artificial substrates and managed areas.
    The resulting specific areas are where we consider the essential 
feature to be distributed currently within each island unit and depth 
range, based on the best available information. However, on smaller 
spatial scales, there are likely locations within the specific areas 
that lack the essential feature, and the exact locations with and 
without the essential feature are likely to change somewhat over time 
in response to changing conditions. Thus, the specific areas described 
below are intended to delineate areas containing the essential feature, 
rather than areas made up completely and permanently of the essential 
feature. As described in detail in the Information Report (NMFS, 2023), 
these 4 steps were applied to each of the 18 units to delineate the 
specific areas of proposed coral critical habitat in more detail than 
in the 2020 proposed rule.

Unoccupied Critical Habitat Areas

    Section 3(5)(A)(ii) of the ESA authorizes the designation of 
specific areas outside the geographical area occupied by the species 
(referred to here as ``unoccupied areas''), if those areas are 
determined to be essential for the conservation of the species. Our 
regulations at 50 CFR 424.12(b)(2) require that we first evaluate areas 
occupied by the species, and only consider unoccupied areas to be 
essential where a critical habitat designation limited to geographical 
areas occupied would be inadequate to ensure the conservation of the 
species.
    To evaluate unoccupied areas that may qualify as critical habitat, 
we first considered the ranges at the time of listing of the five coral 
species that occur in areas under U.S. jurisdiction (NMFS 2023). The 
best available data provides no evidence that those occupied areas have 
been reduced from the historical ranges for any of the five listed 
species. Areas within U.S. jurisdiction that are outside the occupied 
ranges and that could serve as habitat for these species represent <1% 
of the area of each of their current ranges. Because these species 
still occupy their historical ranges, the feature essential to their 
conservation is present in these areas, and the unoccupied areas 
represent a very small amount of potential habitat, we find the 
occupied areas adequate to ensure the conservation of the species 
(NMFS, 2023). Thus, we are not proposing to designate any unoccupied 
areas within U.S. jurisdiction as critical habitat. The impacts of 
global climate change-related threats (especially ocean warming and 
ocean acidification) to the listed corals and their habitats are 
projected to substantially worsen in the foreseeable future, which may 
result in range shifts for some or all of the 5 listed coral species, 
as well as the other 10 species of corals that occur outside U.S. 
jurisdiction. For the five species occurring within U.S. waters, the 
areas outside their occupied ranges mostly occur along the northern 
edges of their ranges, thus ocean warming could make the ocean 
temperatures of these areas more suitable for the listed species in the 
foreseeable future. In contrast, ocean acidification is likely to have 
the opposite effect, causing ocean pH levels along the northern fringes 
of the species' ranges to become less suitable (Brainard et al. 2011, 
NMFS 2014). However, it is not possible to determine where such changes 
are likely to happen, and how they would affect any of the listed 
species' habitat.
    We also considered whether these conclusions would differ under the 
regulations that were in effect prior to the revisions to the 
regulations in 50 CFR 424.12(b)(2) in 2019 (see 84 FR 45020, August 27, 
2019). We conclude that while our analysis would necessarily differ, 
the decision not to propose designating any unoccupied areas would not 
be any different. Because the five coral species each still occupy 
their historical ranges, the feature essential to their conservation is 
present in these areas, and unoccupied areas represent a very small 
amount of potential habitat, we cannot conclude that any unoccupied 
areas are essential to their conservation.

Application of ESA Section 4(a)(3)(B)(i) (INRMPs)

    Section 4(a)(3)(B)(i) of the ESA prohibits designating as critical 
habitat any lands or other geographical areas owned or controlled by 
the Department of Defense (DOD), or designated for its use, that are 
subject to an Integrated Natural Resources Management Plan (INRMP) 
prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if the 
Secretary of Commerce determines in writing that such plan provides a 
benefit to the species for which critical habitat is proposed for 
designation.
    Two INRMPs are applicable to the proposed coral critical habitat: 
(1) The Navy's Joint Region Marianas INRMP (JRM INRMP), finalized and 
signed in 2019 (DON, 2019a); and (2) the Air Force's INRMP for Wake 
Island Air Field, Wake Atoll, Kokee Air Force Station, Kauai, Hawaii, 
and Mt. Kaala Air Force Station, Oahu, Hawaii (Wake INRMP), finalized 
and signed in 2023 (USAF, 2023a). The JRM INRMP is a composite of 
management plans for many distinct DOD-controlled areas in the Mariana 
Islands, including areas in Guam, Tinian, and FDM (DON, 2019a).
    Summaries of the analyses in the Information Report (NMFS, 2023) of 
whether these two INRMPs are likely to benefit the ESA-listed corals or 
their habitat in Guam and CNMI (JRM INRMP) and Wake (Wake INRMP) are 
provided below. The analyses address the four considerations outlined 
in our implementing regulations at 50 CFR 424.12(h). These four 
considerations are: (1) the extent of the area and essential feature 
present in the area; (2) The type and frequency of use of the area by 
the listed species; (3) The

[[Page 83655]]

relevant elements of the INRMP in terms of management objectives, 
activities covered, and best management practices, and the certainty 
that the relevant elements will be implemented; and (4) The degree to 
which the relevant elements of the INRMP will protect the habitat 
(essential feature) from the types of effects that would be addressed 
through a destruction-or-adverse-modification analysis under section 7 
of the ESA.

JRM INRMP--Guam

    In Guam, the JRM INRMP encompasses three marine areas (hereafter 
``INRMP marine areas'') that include potential proposed coral critical 
habitat for the one listed coral that occurs in the Mariana Islands, A. 
globiceps: (1) Naval Base Guam--Main Base (NBG Main Base) Submerged 
Lands; (2) Naval Base Guam--Telecommunications Site (NBG TS) Submerged 
Lands; and (3) Andersen Air Force Base (AAFB) Submerged Lands. A 
summary of the analyses of whether the INRMP is likely to benefit the 
habitat of A. globiceps in each of these three INRMP marine areas is 
provided below, from the full analyses in the Information Report (NMFS, 
2023).
    With regard to the extent of the area and essential feature 
present: (1) the NBG Main Base Submerged Lands cover approximately 
30,000 acres (12,100 hectares) along the coastline from Orote Peninsula 
to Asan (described in the JRM INRMP, section 5.3, DON, 2019a); (2) the 
NBG TS Submerged Lands cover approximately 19,500 acres on the 
northwestern side of Guam (described in the JRM INRMP, section 8.3, 
DON, 2019a); and (3) AAFB Submerged Lands cover approximately 26,500 
acres (10,700 hectares) of Submerged Lands on the northern side of Guam 
(described in the JRM INRMP, section 9.3, DON, 2019a). Each of the 
three INRMP marine areas include extensive habitat for A. globiceps 
(NMFS, 2023). The potential critical habitat within the three INRMP 
marine areas includes both the substrate and water quality components 
of the essential feature of coral critical habitat (i.e., 
characteristics of substrate and water quality to support coral life 
history, including reproduction, recruitment, growth, and maturation), 
based on information provided in the Guam section of the Information 
Report (NMFS, 2023) and the INRMP (DON, 2019a).
    With regard to the relevant elements of the INRMP, and the 
certainty that the relevant elements will be implemented, the two parts 
of this step are addressed separately below. The relevant elements of 
the JRM INRMP for each INRMP marine area include: (1) for the NBG Main 
Base Submerged Lands, the INRMP includes a Coral Habitat Enhancement 
Plan (section 5.4.2.1), consisting of eight specific actions in three 
categories (three monitoring and adaptive management actions, three 
collaboration with local partners actions, and two reduction of vessel 
impacts actions); (2) for NBG TS Submerged Lands, the INRMP includes a 
Coral Habitat Enhancement plan (section 8.4.2.1), consisting of a 
similar set of eight specific actions as for NBG Main Base; and (3) for 
AAFB Submerged Lands, the INRMP includes a Coral Habitat Enhancement 
plan (section 9.4.2.1), consisting of a similar set of seven specific 
actions as for NBG Main Base, except that there is less focus on 
reduction in vessel impacts because of the much lower vessel traffic 
there. The actions, projects, and updates through the end of 2023 are 
described in detail in the Information Report (NMFS, 2023).
    NMFS concludes that the Navy will implement the relevant elements 
of the JRM INRMP for the previously described three INRMP marine areas 
for three reasons:
    (1) Clear and Recent Documentation--the 2019 JRM INRMP includes 
Coral Habitat Enhancement plans for INRMP marine areas in Guam, with 
clear strategies and actions that address the habitat conservation 
needs of ESA-listed corals within these areas. The JRM INRMP's appendix 
D also includes annual reports describing how coral conservation 
efforts had been implemented in the years leading up to the 2019 final 
INRMP. These coral habitat conservation plans, as well as progress 
reports from the most recent years (DON, 2019b, 2020, 2021a,b,c,d, 
2023), clearly articulate how the Navy is conserving coral habitat 
within the INRMP marine areas in Guam, and how it is planning to do so 
in the future.
    (2) Demonstration of Good Faith Efforts for Listed Corals--the Navy 
has already implemented coral habitat conservation projects that are 
beneficial to ESA-listed corals within some INRMP marine areas in Guam, 
as described in the INRMP itself and its appendix D (DON, 2019b), as 
well as progress reports (DON, 2019b, 2020, 2021a,b,c,d, 2023). Many of 
these projects have been ongoing for several years and are proactive, 
in that they were not required of the Navy by the ESA.
    (3) History of Strong Conservation Work--in our experience working 
with the Navy on the development of the marine resource components of 
its 2013 and 2019 final INRMPs (DON, 2013, 2019a), we have found the 
Navy to be successful at carrying out marine habitat conservation work 
on Guam, and that it often takes the initiative on conservation efforts 
whether requested by NMFS or not. For example, many of the coral 
habitat conservation projects in the 2019 JRM INRMP (DON, 2019a) and 
progress reports (DON, 2019b, 2020, 2021a,b,c,d, 2023) had already been 
started by the Navy before corals were listed in 2014, and were being 
done to improve conservation of marine resources on the island, 
regardless of whether they were required by Federal statute or not.
    The coral habitat enhancement elements of the JRM INRMP described 
previously are expected to substantially reduce the types of effects 
within the three INRMP marine areas in Guam that would be addressed 
through the destruction-or-adverse-modification analysis. The Navy 
would accomplish this primarily by using the results of its own 
monitoring program to develop and implement management measures to 
minimize the impacts of the Navy's actions in Guam on coral habitat 
within the INRMP marine areas. Thus, implementation of the JRM INRMP is 
likely to provide substantial protection to the essential feature of 
coral critical habitat (reproductive, recruitment, growth, and 
maturation habitat) within the Guam INRMP marine areas from the types 
of effects that would be addressed through critical habitat 
consultation (DON, 2021a,b,d, 2023).

JRM INRMP--CNMI

    In CNMI, the JRM INRMP encompasses two marine areas that include 
potential proposed coral critical habitat for the one listed coral that 
occurs in the Mariana Islands, A. globiceps: (1) the Tinian Marine 
Lease Area (Tinian MLA) Submerged Lands; and (2) the Farallon de 
Medinilla (FDM) Submerged Lands (DON, 2019a). A summary of the analyses 
of whether the INRMP is likely to benefit the habitat of A. globiceps 
in each of these two INRMP marine areas is provided below, from the 
full analyses in the Information Report (NMFS, 2023).
    With regard to the extent of the area and essential feature 
present: (1) the Tinian MLA Submerged Lands cover approximately 47,500 
acres (19,200 hectares) surrounding the northern portion of Tinian 
(described in the JRM INRMP, section 11.3, DON, 2019a); (2) the FDM 
Submerged Lands consists of approximately 25,000 acres (10,100 
hectares) surrounding FDM (described in the JRM INRMP, section 12.3, 
DON, 2019a). Most or all of the potential critical habitat within the 
two INRMP marine areas includes both the substrate and water quality 
components of the

[[Page 83656]]

essential feature of coral critical habitat (i.e., characteristics of 
substrate and water quality to support coral life history, including 
reproduction, recruitment, growth, and maturation), based on 
information provided in the Tinian and FDM sections of the Information 
Report (NMFS, 2023) and the INRMP (DON, 2019a).
    With regard to the relevant elements of the INRMP, and the 
certainty that the relevant elements will be implemented, the two parts 
of this step are addressed separately below. The relevant elements of 
the JRM INRMP for each INRMP marine area include: (1) for the Tinian 
MLA Submerged Lands, the INRMP includes a Coral Habitat Enhancement 
plan, consisting of three specific actions to enhance coral habitat by 
monitoring health and acute impacts (section 11.4.2.1; DON, 2019a); and 
(2) for the FDM Submerged Lands, the INRMP includes marine habitat 
management actions, consisting of surveys and mapping of ESA-listed 
corals, coral reef, and other marine habitats within the area (section 
12.4.2; DON, 2019a). The INRMP also includes an assessment of ESA-
listed corals, as required by the 2015 biological opinion on the Navy's 
Mariana Islands Testing and Training program (section 12.4.2.2; DON, 
2019a). The actions, projects, and updates through the end of 2021, are 
described in detail in the Information Report (NMFS, 2023).
    NMFS concludes that the Navy will implement these relevant elements 
of the JRM INRMP for three reasons:
    (1) Clear and Recent Documentation--the 2019 JRM INRMP includes 
Coral Habitat Enhancement plans for INRMP marine areas in CNMI (Tinian 
MLA, FDM Submerged Lands), with clear strategies and actions that 
address the habitat conservation needs of ESA-listed corals within 
these areas. The JRM INRMP's appendix D also includes annual reports 
describing how coral conservation efforts had been implemented in the 
years leading up to the 2019 final INRMP. These coral habitat 
conservation plans, as well as progress reports from the most recent 
years (DON, 2019b, 2020, 2021a,b,c,d, 2023), clearly articulate how the 
Navy is conserving coral habitat within the INRMP marine areas in CNMI, 
and how it will do so in the future.
    (2) Demonstration of Good Faith Efforts for Listed Corals--the Navy 
has already implemented coral projects that have the potential to 
benefit the habitat of ESA-listed corals within INRMP marine areas in 
CNMI (Tinian MLA, FDM Submerged Lands). For example, coral species 
presence and abundance surveys were conducted within the Tinian MLA in 
2013 (Tetra Tech, 2014) and 2017 (DON, 2017), and around FDM in 2012 
(Smith and Marx, 2016), 2017 (Carilli et al., 2018), and 2022 (DON 
2023). These surveys have the potential to benefit the habitat of ESA-
listed corals by providing the information needed to better protect 
these areas in the future.
    (3) History of Strong Conservation Work--the Navy has a long 
history of carrying out successful marine habitat conservation work in 
the Mariana Islands and often takes the initiative on conservation 
efforts whether requested by NMFS or not. For example, many of the 
coral habitat conservation projects in the 2019 JRM INRMP (DON 2019a) 
and progress reports (DON, 2019b, 2020, 2021a,b,c,d, 2023) had already 
been started by the Navy before corals were listed in 2014. These 
projects were conducted to improve the conservation of marine resources 
on the island, regardless of whether they were required by Federal 
statute or not. While the majority of these projects have been 
implemented in Guam rather than CNMI, the JRM INRMP includes many plans 
for CNMI (as noted above), and the same Navy command (Joint Region 
Marianas) is responsible for carrying out such work in both Guam and 
CNMI.
    The coral habitat enhancement elements of the JRM INRMP described 
above will substantially reduce the types of effects within the INRMP 
marine areas in CNMI that would be addressed through the destruction-
or-adverse-modification analysis. The Navy would accomplish this 
primarily by using the results of its own monitoring program to develop 
and implement management measures to minimize the impacts of the Navy's 
actions in CNMI on coral habitat within the INRMP marine areas. Thus, 
implementation of the JRM INRMP is likely to provide substantial 
protection to the essential feature of coral critical habitat 
(reproductive, recruitment, growth, and maturation habitat) within the 
CNMI INRMP marine areas from the types of effects that would be 
addressed through critical habitat consultation (DON 2021a,c,d, 2023).

Wake INRMP

    On Wake Atoll, the Wake INRMP (USAF, 2023a) encompasses the entire 
area considered for coral critical habitat for the two listed corals on 
the atoll, A. globiceps and A. retusa, as described in the Information 
Report (NMFS, 2023). A summary of the analyses of whether the INRMP is 
likely to benefit the habitat of ESA-listed corals in this INRMP marine 
area is provided below, from the full analyses in the Information 
Report (NMFS, 2023).
    With regard to the extent of the area and essential feature 
present, the Wake INRMP marine area includes nearly 500,000 acres 
(202,300 hectares) of Submerged Lands and waters within the lagoon and 
surrounding the atoll out to 12 nautical miles (22.2 km) from the mean 
low water line (USAF, 2023a), and thus includes all reef-building 
corals and coral reefs associated with the atoll. Most or all of the 
potential critical habitat within the INRMP marine area includes both 
the substrate and water quality components of the essential feature of 
coral critical habitat (i.e., reproductive, recruitment, growth, and 
maturation habitat provided by suitable substrate and suitable water 
quality), based on information provided in the Wake section of the 
Information Report (NMFS, 2023) and the INRMP (USAF, 2023a).
    With regard to the relevant elements of the INRMP, and the 
certainty that the relevant elements will be implemented, the two parts 
of this step are addressed separately below. The relevant element of 
the Wake INRMP is the coral conservation component that was added to 
the INMRP in 2017 (Appendix K, Coral Conservation Actions at Wake 
Atoll; USAF, 2023a), which is made up of four groups of actions, each 
of which includes multiple projects: Water quality improvements (six 
projects), education and outreach (two projects), fisheries management 
(four projects), and physical DOD presence on Wake Atoll (three 
projects; USAF, 2023a). The actions, projects, and updates through the 
end of 2021, are described in detail in the Information Report (NMFS, 
2023).
    NMFS concludes that the Air Force will implement these relevant 
elements of the Wake INRMP for three reasons:
    (1) Clear and Recent Documentation--the Wake INRMP includes a coral 
conservation plan (USAF, 2023a) with a 4-pronged strategy (water 
quality improvement, outreach and education for Wake-based staff, 
fisheries management, and physical DOD presence on Wake Atoll, i.e., 
restriction of access and overall natural resource management) that 
comprehensively addresses the conservation needs of ESA-listed corals 
on Wake Atoll. This coral conservation plan clearly articulates how 
U.S. Air Force (USAF) is conserving corals on Wake, and how it will do 
so in the future. The ongoing implementation of the Wake INRMP is 
reported via progress updates and reviews (USAF, 2018, 2019, 2021a,b, 
2023b).
    (2) Demonstration of Good Faith Efforts for Listed Corals--In the 
years

[[Page 83657]]

leading up to the final Wake INRMP (USAF, 2023a), USAF implemented 
projects on Wake related to each of its 4-pronged coral conservation 
strategy, as explained in appendix S of the Wake INRMP. For water 
quality improvement, in 2016 USAF began implementation of both the 
stormwater pollution prevention and invasive plant control projects. 
For outreach and education, in 2016 USAF revised the Wake Island Dive 
Club Charter to further reduce the potential impacts of recreational 
activities on corals. For fisheries management, in 2017 USAF updated 
its fishing rules, which are part of the Wake Island Operating 
Guidance, to prohibit the use of (1) cast nets on the exterior of the 
atoll, (2) anchoring on coral reef habitat, and (3) and trolling over 
coral reef habitat. For physical DOD presence on Wake Atoll, in 2016 
USAF funded and provided logistical support for a Fish and Wildlife 
Service (FWS) coral survey that documented two ESA-listed corals on the 
atoll for the first time. Since 2017, USAF has implemented projects on 
Wake for each of its 4-pronged coral conservation strategy, as noted 
above in the 2021 updates, and detailed in the progress updates and 
reviews (USAF, 2018, 2019, 2021a,b, 2023b).
    (3) History of Strong Conservation Work--USAF has a long history of 
carrying out successful conservation work on Wake and often takes the 
initiative on conservation efforts whether requested by NMFS or not. 
For example, many of the projects in the INRMP's coral conservation 
strategy had already been started by USAF before corals were listed in 
2014, and were being done to improve the conservation of marine and 
terrestrial resources on the atoll, regardless of whether they were 
required by Federal statute or not. Likewise, in 2016, USAF funded and 
supported the FWS coral survey of the atoll, leading to the discovery 
that the two ESA-listed corals occur on the atoll. In addition, USAF 
has historically been a strong conservation partner with NMFS, 
supporting a wide variety of marine and terrestrial conservation 
projects, and actively engaging both agencies in the INRMP planning and 
implementation process, as described in the progress updates and 
reviews (USAF, 2018, 2019, 2021a,b, 2023b).
    The coral conservation component of the Wake INRMP (Appendix K, 
Coral Conservation Actions at Wake Atoll; USAF, 2023a) is expected to 
reduce both direct and indirect impacts to listed corals via 
minimization or avoidance of recreational impacts (fishing, diving, 
anchoring), and terrestrial impacts (i.e., run-off from land-based 
activities), thereby addressing two of the primary threats to listed 
corals (fishing and land-based sources of pollution). That is, the 
coral conservation elements of the Wake Atoll INRMP described 
previously are expected to substantially reduce the types of effects at 
Wake Atoll that would be addressed through the destruction-or-adverse-
modification analysis. Based on the fact that the Wake INRMP's coral 
conservation strategy is well-designed to reduce impacts to listed 
corals, and also that recent progress updates and reviews (USAF, 2018, 
2019, 2021a,b, 2023b) demonstrate substantial progress with the 
implementation of the strategy, we determined that the Wake INRMP 
provides a benefit to listed corals, and their critical habitat 
(reproductive, recruitment, growth, and maturation habitat).

Conclusion Regarding Areas Subject to INRMPs

    Based on the analyses summarized previously and provided in the 
Information Report (NMFS, 2023), we conclude both the JRM INRMP (DON, 
2019a) and the Wake INRMP (USAF, 2023a) provide a conservation benefit 
to the listed corals and their habitats within all INRMP marine areas 
on Guam, CNMI, and Wake. Thus, the potential coral critical habitat 
areas within the INRMP marine areas on Guam, Tinian, FDM, and Wake are 
ineligible for designation as critical habitat.

Application of ESA Section 4(b)(2)

    Section 4(b)(2) of the ESA requires that we consider the economic 
impact, impact on national security, and any other relevant impact, of 
designating any particular area as critical habitat. Additionally, the 
Secretary has the discretion to consider excluding any area from 
critical habitat if they determine that the benefits of exclusion (that 
is, avoiding some or all of the impacts that would result from 
designation) outweigh the benefits of designation based upon the best 
scientific and commercial data available. The Secretary may not exclude 
an area from designation if exclusion will result in the extinction of 
the species.
    The following sub-sections summarize the economic, national 
security, and other relevant impacts analyses in the Information Report 
(NMFS, 2023) that we projected would result from proposed coral 
critical habitat. We considered these impacts when deciding whether to 
exercise our discretion to exclude particular areas from the 
designation. Both positive and negative impacts were identified and 
considered (these terms are used interchangeably with benefits and 
costs, respectively). Impacts were evaluated in quantitative terms 
where feasible, but qualitative appraisals were used where that is more 
appropriate.
    The primary impacts of a critical habitat designation result from 
the ESA section 7(a)(2) requirement that Federal agencies ensure that 
their actions are not likely to result in the destruction or adverse 
modification of critical habitat and that they consult with NMFS in 
fulfilling this requirement. The impacts of designating coral critical 
habitat are only those that would be in addition to the impacts of 
listing (i.e., incremental impacts). The distribution of listed corals 
within critical habitat strongly influences the extent of incremental 
impacts. That is, the more colonies of listed corals that are 
distributed throughout coral critical habitat, the lower the proportion 
of Federal actions that would affect critical habitat but not listed 
corals, and thus the lower the incremental impacts of critical habitat 
designation. As described in section 3.3.19 of the Information Report 
(NMFS, 2023), colonies of listed corals are generally distributed 
throughout the specific areas being considered for proposed coral 
critical habitat, thus the incremental impacts are expected to be quite 
low.
    Summaries of the economic, national security, and other relevant 
impact analyses in the Information Report (NMFS, 2023) are provided 
below. The analyses follow the guidance for 4(b)(2) analyses provided 
in our 2016 policy (81 FR 7226, February 11, 2016) and regulations at 
50 CFR 424.19.

4(b)(2) Economic Impact Analysis

    The economic impacts of designating the areas identified as coral 
critical habitat are analyzed in the full 4(b)(2) Economic Impact 
Analysis document, completed in late 2021, which is appendix C of the 
Information Report (NMFS, 2023). Economic impacts are projected for the 
10-year period 2022-2031, and uncertainty is accounted for by using 
low-end and high-end scenarios to estimate incremental impacts. The 
Economic Impact Analysis Report (NMFS, 2023, appendix C) presents 
economic impacts in terms of present value versus annualized costs. For 
example, table 17 of the report summarizes the low-end estimated cost 
of coral critical habitat as $373,171 in terms of the present value of 
the total cost over the 10-yr period of 2022-2031, with an estimated 
annualized cost of $53,131 over that 10-yr period. Present value over 
the 10-year period is not

[[Page 83658]]

simply 10 times the annualized cost because present value represents 
the sum of a series of past or future cash flows discounted at a 
specified discount rate (in this case, 7 percent) and expressed in 
constant dollars, whereas annualized cost provides a comparison of 
impacts across activities with varying forecast periods (NMFS, 2023, 
appendix C).
    For the low-end scenario, total incremental costs over the 10-year 
period are estimated at $373,171 for all jurisdictions combined or 
$53,131 annualized. These are entirely administrative costs since the 
low-end scenario assumes that no project modifications would be 
required. For the high-end scenario, total incremental costs over the 
10-year period are estimated at $6,815,860 for all jurisdictions 
combined or $970,425 annualized. Of these costs, 95 percent are derived 
from project modifications because, for purposes of this analysis, the 
high-end scenario assumes that 100 percent of section 7 consultations 
will be formal consultations that result in the need for project 
modifications to avoid destruction or adverse modification of the 
critical habitat. The jurisdiction with the highest economic impacts in 
both scenarios is Guam, due to the relatively high number of expected 
consultations there (NMFS, 2023).
    While the low-end vs. high-end scenarios are useful for 
illustrating the range of potential economic impacts, the following 
points are relevant to interpreting the results:
    (1) Both scenarios assumed that proposed coral critical habitat 
would be 0-50 m depth around all island units considered in proposed 
coral critical habitat; however, proposed coral critical habitat is 0-
50 m depth on just one island (Tutuila) and 0-20 m, 0-12 m, and 0-10 m 
on the others.
    (2) Colonies of listed corals occur within all specific areas being 
considered for proposed coral critical habitat (NMFS, 2023, appendix 
A), thus reducing incremental impacts. That is, since colonies of 
listed corals occur in all specific areas of proposed coral critical 
habitat, there would be a low proportion of future Federal actions that 
would affect critical habitat but not listed corals. As the proposed 
coral critical habitat will not include extensive areas where listed 
coral colonies are absent, the incremental impacts of proposed coral 
critical habitat are likely to be quite low, which minimizes economic 
impacts.
    (3) A comparison of projected vs. actual consultations in 2016-2019 
was included in the economic analysis done for the 2020 proposed coral 
critical habitat rule (NMFS 2020, appendix B), which showed that three 
times more formal consultations were projected in the high-end scenario 
than actually occurred. That is, the reality of consultations was more 
similar to the low-end scenario than the high-end scenario.
    For these reasons, it is reasonable to conclude that the actual 
economic impacts are likely to be much closer to those projected in the 
low-end scenario than the high-end scenario. In addition, economic 
benefits would be relatively high in the high-end scenario (because 
project modifications would provide better protection of coral reef 
ecosystems, which produce economic benefits, as described in section 
5.1.6 of the Information Report (NMFS, 2023), but lower in the low-end 
scenario (because there would be no project modifications, and thus no 
increased protection of coral reef ecosystems).

4(b)(2) National Security Impact Analysis

    We received a request from the Department of the Navy (Navy) to 
exclude one site based on national security impacts: The portion of the 
Navy's Ritidian Point Surface Danger Zone (SDZ) Complex outside of DOD 
Submerged Lands on Guam. For this site, we weighed the national 
security impacts of designating the site as critical habitat against 
the conservation benefits to the listed corals of designating the site 
as critical habitat. If impacts to national security outweigh the 
benefits of including an area in the designation, the Secretary may 
exercise her discretion to exclude that particular area from critical 
habitat. If the benefits of including the area in the designation 
outweigh the impacts to national security, however, the site cannot be 
considered for exclusion from critical habitat (81 FR 7226, February 
11, 2016).
    The Ritidian Point SDZ complex overlaps with a small area of 
forereef identified for potential designation as coral critical 
habitat. The area is 0-12 m of depth and consists primarily of spur-
and-groove and aggregate reef that provides high quality coral habitat. 
A species-level coral survey conducted in 2021 at this site indicated 
that A. globiceps was present, finding a total of four colonies along 
eight 50-m transects at 6 m depth within forereef habitat at the site. 
In contrast, a species-level coral survey conducted in 2006 at this 
site did not find any A. globiceps colonies along a different set of 
eight 50-m transects between 1 and 20 m within forereef and reef flat 
habitat (NMFS, 2023).
    National security impacts depend on the additional section 7 
requirements that would result from the coral critical habitat, above 
and beyond those already required to avoid jeopardizing the continued 
existence of any listed species or avoid destruction or adverse 
modification of other, designated critical habitats (i.e. incremental 
impacts). The Navy noted that the Ritidian Point SDZ complex supports 
training at the Marine Corps Live Fire Training Range Complex (LFTRC) 
at AAFB, and construction of new facilities (e.g., range administration 
building, range maintenance building, and observation towers) at AAFB, 
to meet the individual weapons training/qualification requirements of 
the Marine Corps. This SDZ is expected to be operational for 32 weeks 
per year and extends approximately 2 miles over open water in the event 
stray bullets go over the berm and into the ocean. If this occurs, the 
bullets will settle on the seafloor (NMFS, 2023).
    The Navy stated that designation of the marine component of this 
site as coral critical habitat would result in limitations on live fire 
training at LFTRC. The Navy explained that such limitations would occur 
because limited staff time and resources would be diverted to preparing 
additional documents required to implement activities in critical 
habitat areas from work required on other vital environmental items. In 
2021 and 2022, the Navy confirmed that this information is still 
applicable to the site. Because many training and construction 
activities are planned at LFTRC adjacent to this marine area, the 
listed coral A. globiceps occurs there, and the planned activities have 
the potential to affect this listed species, ESA section 7 
consultations would likely be necessary whether critical habitat is 
designated or not. That is, the additional consultation requirement 
above and beyond what would already be required by the fact that listed 
corals occur at the site is not expected to be substantial. Also, the 
additional consultation for critical habitat would be for activities 
that are planned in advance, and thus the additional section 7 
consultation workload would not be unpredictable but rather could be 
anticipated and managed ahead of time.
    The Navy noted that the individual live fire training for Marine 
Corps personnel at the LFTRC on Guam is a prerequisite for conducting 
unit level and combined level training. The Navy further explained that 
without the qualification of these live fire training events, 
individuals and small teams are not capable of conducting larger unit

[[Page 83659]]

collective events, and that the LFTRC provides the necessary foundation 
for which training progression is built upon. Plans are in place to 
considerably expand LFTRC in anticipation of growing Marine Corps 
training needs. No other facility on Guam or elsewhere in the Mariana 
Islands provides this type of training. In 2021 and 2022, the Navy 
confirmed that this information is still applicable to the site (NMFS, 
2023).
    In determining benefits to the conservation of ESA-listed corals we 
considered whether designation of critical habitat at the particular 
site would lead to additional conservation of the species beyond what 
is already provided by the species' listing. The potential for 
additional conservation at a given site is a function of the listed 
corals' use of the area, the level of protection already provided by 
existing management (e.g., the site is entirely within Guam National 
Wildlife Refuge), and the likelihood of non-DOD actions that are likely 
to affect the area and that are subject to the consultation 
requirements of section 7.
    As elsewhere on Guam, the coral reef habitat within the area being 
considered for proposed coral critical habitat is made up of forereef 
from 0--12 m depth, consisting primarily of spur-and-groove and 
aggregate reef. As noted above, A. globiceps occurs at this site. 
However, colonies of the species may die off in response to natural 
disturbances and not reappear for a few years, which may be why the 
2021 survey found A. globiceps there but the 2006 survey did not 
despite surveying within the same habitat and depth range. Such 
mortality and recovery and associated disappearance and reappearance of 
coral populations at any given site is a normal response to natural 
disturbance. Critical habitat protects the essential feature whether 
colonies of the listed coral species occur at the site at the time of 
consultation or not.
    The area being considered for potential designation as coral 
critical habitat is entirely within U.S. Fish and Wildlife Service 
(USFWS) Submerged Lands, which forms the marine component of the Guam 
National Wildlife Refuge (NWR), and is managed according to the Guam 
NWR Comprehensive Conservation Plan. The plan includes Strategies to 
Restore, Protect, and Maintain Native Marine Communities, such as 
marine debris removal and area closures. The site is also entirely 
within Essential Fish Habitat (EFH) for coral reef ecosystems, but EFH 
protections are not mandatory (NMFS, 2023).
    It is possible that non-DOD Federal actions will be proposed within 
this site that could affect the essential feature (e.g., actions 
proposed by USFWS), but that would no longer be subject to the critical 
habitat provision if the particular area were excluded from the 
designation. When the site is not closed by the SDZ, non-DOD actions 
could potentially occur there, for example those permitted or carried 
out by USFWS. Although such actions would presumably be consistent with 
the Guam NWR Comprehensive Conservation Plan (USFWS 2009), they may 
affect the essential feature (NMFS, 2023).
    Based on the considerations described above, we conclude that the 
impacts to national security of including this area within critical 
habitat do not outweigh the conservation benefits to the listed corals, 
and thus do not propose to exclude the Ritidian Point SDZ complex from 
proposed coral critical habitat designation. The most important factors 
supporting this recommendation are: (1) the national security impacts 
of coral critical habitat are unlikely to be either substantial or 
unpredictable because listed corals are known to occur at this site at 
least some of the time, meaning that the Navy would already be 
conducting section 7 consultations on listed corals for any of their 
activities that may affect listed corals at this site even without 
critical habitat, resulting in little additional consultation work; and 
(2) the conservation benefits of coral critical habitat could be 
considerable because critical habitat would provide additional 
protection of the high quality essential feature that is found 
throughout the area from future proposed Federal actions (NMFS, 2023).

Other Relevant Impacts

    Other relevant impacts include the benefits of critical habitat 
designation and impacts on governmental or private entities that are 
implementing existing management plans that provide benefits to the 
listed species. The three main types of benefits of critical habitat 
designation are increased protection of the essential feature from 
Federal actions, ecosystem service benefits of coral reef conservation, 
and education and awareness.
    Critical habitat is habitat needed to support recovery of listed 
species. That is, the most direct benefits of the critical habitat 
designation stem from the increased protection of the essential feature 
from Federal actions. While listed corals are generally distributed 
throughout the specific areas, there are still many locations within 
the specific areas that lack colonies of listed corals at any given 
point in time due to natural spatial and temporal fluctuations of coral 
colony presence. That is, individual colonies of listed corals may 
decrease or disappear from particular locations in response to local 
disturbances, then return and increase as local conditions improve. 
Such dynamic spatial and temporal fluctuations in the distribution of 
colonies of listed corals within the specific areas is a natural 
process. Critical habitat thus protects the essential feature in 
locations and during times when specific areas lack colonies of listed 
corals and Federal actions are proposed at that location (NMFS, 2023).
    Overall, coral reef ecosystems, including those comprising 
populations of the listed corals, provide important ecosystem services 
of value to individuals, communities, and economies. These include 
recreational opportunities (and associated tourism spending in the 
regional economy), habitat and nursery functions for recreationally and 
commercially valuable fish species, shoreline protection in the form of 
wave attenuation and reduced beach erosion, and climate stabilization 
via carbon sequestration. As of 2021, the total economic value of coral 
reefs in the three U.S. Pacific Islands jurisdictions where the great 
majority of critical habitat is being proposed is (1) American Samoa--
$13.4 million/year, (2) Guam--$165.0 million/year, and (3) CNMI--$60.4 
million/year (NMFS, 2023). Efforts to conserve the listed corals also 
benefit the broader reef ecosystems, thereby preserving or improving 
these ecosystem services and values (NOAA Coral Reef Conservation 
Program, 2013). While we cannot quantify the precise economic benefits 
of designating critical habitat, providing these values gives an 
indication of the value of conserving coral habitat.
    There is the potential for education and awareness benefits arising 
from the critical habitat designation, stemming from entities that 
engage in section 7 consultations, and from members of the general 
public interested in coral conservation. Entities that engage in 
section 7 consultations may alter their activities to benefit the 
species or essential feature because they were made aware of the 
critical habitat designation through either the section 7 consultation 
process or the original listings. Members of the public may engage in 
similar efforts because they learned of the critical habitat 
designation through outreach materials (NMFS, 2023).
    Impacts may also occur to governmental or private entities that are

[[Page 83660]]

implementing existing management plans that provide benefits to the 
listed species, although such potential impacts would be limited to 
actions that have a Federal nexus and affect critical habitat.
    There are a large number of Federal marine protected areas in 
American Samoa, Guam, CNMI, PRIA, and NWHI where coral critical habitat 
is being proposed, and many of these jurisdictions have draft or 
proposed management plans (NMFS, 2023). Impacts of critical habitat 
designation on the agencies responsible for natural resource management 
planning of these areas (e.g., the National Park Service, USFWS, and 
Territorial natural resources management agencies), depend on the type 
and number of section 7 consultations that may result from the 
designation in the areas covered by those plans, as well as any 
potential project modifications recommended by these consultations. 
Negative impacts to these entities could result if the critical habitat 
designation interferes with these agencies' ability to provide for the 
conservation of the species, or otherwise hampers the management of 
these areas.
    Existing or proposed management plans in the marine protected areas 
and their associated regulations protect existing coral reef resources, 
but they may not specifically protect the substrate and water quality 
components of the essential feature for purposes of increasing listed 
coral abundance and eventual recovery. However, section 7 consultations 
on the implementation of these Federal marine protected area plans over 
the next 10 years are not expected to result in incremental project 
modifications, thus any section 7 impacts will likely be limited to 
administrative costs (NMFS, 2023, appendix C).

Conclusions for Section 4(b)(2)

    We are not exercising our discretion to exclude any areas from the 
proposed coral critical habitat based on economic or national security 
impacts. As summarized in the 4(b)(2) Economic Impact Analysis section, 
the economic impacts of the proposed coral critical habitat are likely 
to be low, even on the islands with concentrated economic activity 
(Tutuila, Guam, Saipan). Since these are the three units where most 
future proposed Federal actions that could affect critical habitat are 
expected (NMFS, 2023, appendix C), the conservation benefits of 
critical habitat are the greatest in these three units. Thus, economic 
impacts do not outweigh conservation benefits. Likewise, as summarized 
in the 4(b)(2) National Security Impact Analysis section, the national 
security impacts of the proposed coral critical habitat on the one 
requested exclusion site, the Navy's Ritidian Point Surface Danger Zone 
complex in Guam, are not expected to outweigh the conservation benefits 
of designating critical habitat.

Proposed Critical Habitat Designations

    We are proposing to designate critical habitat for 5 listed coral 
species around 16 islands in 5 U.S. Pacific Islands jurisdictions. For 
A. globiceps, specific areas around all 16 islands are proposed, 
including 4 in American Samoa, 1 in Guam, 9 in CNMI, 3 in PRIA, and 1 
in Hawaii. The depth ranges of the specific areas for A. globiceps are 
0-20 m (3 islands), 0-12 m (9 islands), and 0-10 m (4 islands). For A. 
retusa, specific areas around three islands are proposed, all of which 
are in American Samoa. The depth ranges of the specific areas for A. 
retusa are 0-20 m on all three islands. For A. speciosa and E. 
paradivisa, specific areas around Tutuila and its offshore banks in 
American Samoa are proposed. The depth ranges of the specific areas for 
A. speciosa and E. paradivisa are 20-50 m. For I. crateriformis, 
specific areas around three islands are proposed, all of which are in 
American Samoa. The depth ranges of the specific areas for I. 
crateriformis are 0-20 m on all three islands (table 4). The 
4(a)(3)(B)(i) INRMP analyses found that the entire areas around FDM and 
Wake Atoll, several areas off of Guam, and most of Tinian are 
ineligible for proposed coral critical habitat. Maps of the proposed 
critical habitat for each of the listed species around each of the 16 
islands are provided at the end of this rulemaking (table 4).

Effects of Critical Habitat Designations

    Section 7(a)(2) of the ESA requires Federal agencies, including 
NMFS, to ensure that any action authorized, funded, or carried out by 
the agency does not jeopardize the continued existence of any 
threatened or endangered species or destroy or adversely modify 
designated critical habitat. When a species is listed or critical 
habitat is designated, Federal agencies must consult with NMFS on any 
agency actions to be conducted in an area where the species is present 
and that may affect the species or its critical habitat. During formal 
consultation, NMFS would evaluate the agency's action to determine 
whether the action may adversely affect listed species or designated 
critical habitat and issue its

[[Page 83661]]

findings in a biological opinion. If NMFS concludes in the biological 
opinion that the proposed agency action would likely result in the 
destruction or adverse modification of designated critical habitat, 
NMFS would identify any reasonable and prudent alternatives to the 
action. Reasonable and prudent alternatives are defined in 50 CFR 
402.02 as alternative actions identified during formal consultation 
that can be implemented in a manner consistent with the intended 
purpose of the action, that are consistent with the scope of the 
Federal agency's legal authority and jurisdiction, that are 
economically and technologically feasible, and that would avoid the 
likelihood of jeopardizing the continued existence of listed species or 
resulting in the destruction or adverse modification of critical 
habitat. If NMFS concludes in the biological opinion that the proposed 
agency action would not likely result in the destruction or adverse 
modification of designated critical habitat, NMFS may provide 
discretionary conservation recommendations.
    Regulations at 50 CFR 402.16 require Federal agencies that have 
retained discretionary involvement or control over an action, or where 
such discretionary involvement or control is authorized by law, to 
reinitiate consultation on previously reviewed actions in instances in 
which (1) critical habitat is subsequently designated, or (2) new 
information or changes to the action may result in effects to critical 
habitat not previously considered in the biological opinion. 
Consequently, some Federal agencies may request reinitiation of 
consultation or to conference with NMFS on actions for which formal 
consultation has been completed, if those actions may adversely modify 
or destroy designated critical habitat or adversely modify or destroy 
proposed critical habitat, respectively.

Activities That May Be Affected

    Section 4(b)(8) of the ESA requires that we describe briefly, and 
evaluate in any proposed or final regulation to designate critical 
habitat, those activities that may adversely modify such habitat or 
that may be affected by such designation. A wide variety of Federal 
activities may require ESA section 7 consultation because they may 
affect the essential feature of critical habitat (i.e., suitable 
substrate and suitable water quality). Specific future activities would 
need to be evaluated with respect to their potential to destroy or 
adversely modify critical habitat, in addition to their potential to 
affect and jeopardize the continued existence of listed species. For 
example, activities may adversely modify the essential feature by 
removing or altering the substrate or reducing water clarity through 
turbidity. These activities would require ESA section 7 consultation 
when they are authorized, funded, or carried out by a Federal agency. 
Non-Federal entities may also be affected by these proposed critical 
habitat designations if they are undertaking a project that requires a 
Federal permit or receives Federal funding. Categories of activities 
that may be affected by the designations include in-water and coastal 
construction, dredging and disposal, water quality and discharges, 
fishery management, military activities, shipwreck and marine debris 
removal, scientific research and monitoring, aquaculture, protected 
area management, and beach nourishment/shoreline protection. Further 
information is provided in the Economic Impact Analysis in our 
Information Report (NMFS, 2023, appendix C). Questions regarding 
whether specific activities will constitute destruction or adverse 
modification of critical habitat should be directed to us (see 
ADDRESSES and FOR FURTHER INFORMATION CONTACT).

Public Comments Solicited

    We request that interested persons submit comments, information, 
and suggestions concerning this proposed rule during the comment period 
(see DATES). We are soliciting comments or suggestions from the public, 
other concerned governments and agencies, the scientific community, 
industry, or any other interested party concerning this proposed rule, 
including any foreseeable economic, national security, or other 
relevant impact resulting from the proposed designations. We are 
seeking comments on the changes in this proposed rule from the 2020 
proposed rule, including the following: (1) development of the 
methodology for using records of listed coral species to determine 
their occupied areas for critical habitat; (2) changes to the occupied 
areas for the listed coral species; (3) changes to the depth ranges for 
the listed coral species; and (4) other changes including refinement of 
critical habitat boundaries. These changes are summarized in the 
Summary of Changes From the 2020 Proposed Rule above and described in 
detail in the Information Report (NMFS, 2023). You may submit your 
comments and materials concerning this proposal by any one of several 
methods (see ADDRESSES). Copies of the proposed rule and supporting 
documentation are available at https://www.fisheries.noaa.gov/action/proposed-rule-designate-critical-habitat-threatened-indo-pacific-corals, or upon request (see FOR FURTHER INFORMATION CONTACT). We will 
consider all comments pertaining to this designation received during 
the comment period in preparing the final rule. Accordingly, the final 
designation may differ from this proposal.

Information Quality Act and Peer Review

    The data and analyses supporting this action have undergone a 
predissemination review and have been determined to be in compliance 
with applicable information quality guidelines implementing the 
Information Quality Act (section 515 of Pub. L. 106-554). On December 
16, 2004, OMB issued its Final Information Quality Bulletin for Peer 
Review (Bulletin). The Bulletin was published in the Federal Register 
on January 14, 2005 (70 FR 2664), and went into effect on June 16, 
2005. The primary purpose of the Bulletin is to improve the quality and 
credibility of scientific information disseminated by the Federal 
Government by requiring peer review of ``influential scientific 
information'' and ``highly influential scientific information'' prior 
to public dissemination. ``Influential scientific information'' is 
defined as information the agency reasonably can determine will have or 
does have a clear and substantial impact on important public policies 
or private sector decisions. The Bulletin provides agencies broad 
discretion in determining the appropriate process and level of peer 
review. Stricter standards were established for the peer review of 
highly influential scientific assessments, defined as information whose 
dissemination could have a potential impact of more than $500 million 
in any one year on either the public or private sector or that the 
dissemination is novel, controversial, or precedent-setting, or has 
significant interagency interest.
    The information in the Critical Habitat Information Report (NMFS, 
2023) and its appendices was

[[Page 83662]]

considered influential scientific information and subject to peer 
review. To satisfy our requirements under the OMB Bulletin, we obtained 
independent peer review of the the Critical Habitat Information Report 
(NMFS, 2023) and its appendices. The resulting Peer Review Reports are 
available on our website https://www.noaa.gov/information-technology/endangered-species-act-critical-habitat-designation-for-7-indo-pacific-corals-information-report.

Classification

Takings (Executive Order 12630)

    Under E.O. 12630, Federal agencies must consider the effects of 
their actions on constitutionally protected private property rights and 
avoid unnecessary takings of private property. A taking of property 
includes actions that result in physical invasion or occupancy of 
private property and regulations imposed on private property that 
substantially affect its value or use. In accordance with E.O. 12630, 
this proposed rule would not have significant takings implications, 
because it does not include, occupy or invade private property or 
otherwise affect the value or use of private property to qualify as a 
taking. A takings implication assessment is not required.

Regulatory Planning and Review (E.O.s 12866, 14094, 13563)

    This rulemaking has been determined to be significant for purposes 
of E.O. 12866 as amended by Executive Order 14094. Executive Order 
14094, which amends E.O. 12866 and reaffirms the principles of E.O. 
12866 and E.O 13563, states that regulatory analysis should facilitate 
agency efforts to develop regulations that serve the public interest, 
advance statutory objectives, and be consistent with E.O. 12866, E.O. 
13563, and the Presidential Memorandum of January 20, 2021 (Modernizing 
Regulatory Review). Regulatory analysis, as practicable and 
appropriate, shall recognize distributive impacts and equity, to the 
extent permitted by law. E.O. 13563 emphasizes further that regulations 
must be based on the best available science and that the rulemaking 
process must allow for public participation and an open exchange of 
ideas. We have developed this proposed rule in a manner consistent with 
these requirements.
    A draft economic impact analysis report, which has been prepared as 
part of the Information Report (see appendix C of NMFS, 2023), 
considers the economic costs and benefits of this proposed critical 
habitat designation and alternatives to this rulemaking as required 
under E.O. 12866. Based on the impact analysis report, low-end total 
incremental costs over the 10-year period are estimated at $373,171 for 
all jurisdictions combined or $53,131 annualized. These are 100 percent 
administrative costs since the low-end scenario assumes that no project 
modifications will be required. For the high-end, total incremental 
costs over the 10-year period are estimated at $6,815,860 for all 
jurisdictions combined or $970,425 annualized. Of these costs, 95 
percent are derived from project modifications since the high-end 
scenario assumes that 100 percent of section 7 consultations will be 
formal. The jurisdiction with the highest economic impacts in both 
scenarios is Guam, due to the relatively high number of expected 
consultations there (NMFS, 2023, appendix C).
    As explained under the 4(b)(2) Economic Impact Analysis, we find 
that the actual economic impacts are likely to be much closer to the 
low-end scenario's projections than the high-end scenario's 
projections. In addition, economic benefits would be relatively high in 
the high-end scenario (because project modifications would provide 
better protection of coral reef ecosystems, which produce economic 
benefits), but non-existent in the low-end scenario (because there 
would be no project modifications, and thus no increased protection of 
coral reef ecosystems). We conclude that the economic impacts of the 
proposed coral critical habitat are likely to be much closer to those 
projected by the low-end scenario than the high-end scenario, and also 
that there would be low economic benefits. That is, we find that the 
economic analysis and IRFA support the conclusion that the proposed 
coral critical habitat would have low economic effects on small 
entities. A proposed Economic Impact Analysis Report (appendix C of the 
Information Report; NMFS, 2023) and Final ESA section 4(b)(2) Report 
(i.e., the 4(b)(2) section of the Information Report; NMFS, 2023) have 
been prepared to support the exclusion process under section 4(b)(2) of 
the ESA and our consideration of alternatives to this rulemaking. These 
supporting documents are available at the link provided in ADDRESSES, 
or upon request (see FOR FURTHER INFORMATION CONTACT).

Federalism (E.O. 13132)

    The E.O. on Federalism, Executive Order 13132, requires agencies to 
take into account any federalism impacts of regulations under 
development. It includes specific consultation directives for 
situations in which a regulation may preempt State law or impose 
substantial direct compliance costs on State and local governments 
(unless required by statute). Pursuant to E.O. 13132, we determined 
that this proposed rule does not have significant federalism effects 
and that a federalism assessment is not required. In keeping with 
Department of Commerce policies and consistent with ESA regulations at 
50 CFR 424.16(c)(1)(ii), we requested information for this rulemaking 
from the appropriate marine resources agencies in American Samoa, Guam, 
CNMI, PRIA, and Hawaii. The designation may have some benefit to State 
and local resource agencies in that the rule more clearly defines the 
physical and biological feature essential to the conservation of the 
species and the areas in which that feature is found. While this 
designation would not alter where and what non-federally sponsored 
activities may occur, it may assist local governments in long-range 
planning (rather than waiting for case-by-case ESA section 7 
consultations to occur).
    Where State and local governments require approval or authorization 
from a Federal agency for actions that may affect critical habitat, 
consultation under section 7(a)(2) would be required. While non-Federal 
entities that receive Federal funding, assistance, or permits, or that 
otherwise require approval or authorization from a Federal agency for 
an action, may be indirectly impacted by the designation of critical 
habitat, the legally binding duty to avoid destruction or adverse 
modification of critical habitat rests only on the Federal agency.

Energy Supply, Distribution, and Use (E.O. 13211)

    Executive Order 13211 requires agencies to prepare Statements of 
Energy Effects when undertaking an action expected to lead to the 
promulgation of a final rule or regulation that is a significant 
regulatory action under E.O. 12866 and is likely to have a significant 
adverse effect on the supply, distribution, or use of energy. OMB 
Guidance on Implementing E.O. 13211 (July 13, 2001) states that 
significant adverse effects could include any of the following outcomes 
compared to a world without the regulatory action under consideration: 
(1) reductions in crude oil supply in excess of 10,000 barrels per day; 
(2) reductions in fuel production in excess of 4,000 barrels per day; 
(3) reductions in coal production in excess of 5 million tons (4.5 
million metric tons) per year;

[[Page 83663]]

(4) reductions in natural gas production in excess of 25 million cubic 
feet (708,000 cubic meters) per year; (5) reductions in electricity 
production in excess of 1 billion kilowatt-hours per year or in excess 
of 500 megawatts of installed capacity; (6) increases in energy use 
required by the regulatory action that exceed any of the thresholds 
previously described; (7) increases in the cost of energy production in 
excess of 1 percent; (8) increases in the cost of energy distribution 
in excess of 1 percent; or (9) other similarly adverse outcomes. A 
regulatory action could also have significant adverse effects if it (1) 
adversely affects in a material way the productivity, competition, or 
prices in the energy sector; (2) adversely affects in a material way 
productivity, competition, or prices within a region; (3) creates a 
serious inconsistency or otherwise interferes with an action taken or 
planned by another agency regarding energy; or (4) raises novel legal 
or policy issues adversely affecting the supply, distribution or use of 
energy arising out of legal mandates, the President's priorities, or 
the principles set forth in E.O. 12866 and 13211.
    The economic impacts of this rulemaking are analyzed in the full 
4(b)(2) Economic Impact Analysis, which is appendix C of the 
Information Report (NMFS, 2023). Based on the results of that analysis, 
the economic impacts on energy supply, distribution, and use would 
either be non-existent or far below the above thresholds. Thus, we have 
determined that this rulemaking will not have a significant adverse 
effect on the supply, distribution, or use of energy. Therefore, we 
have not prepared a Statement of Energy Effects.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    We prepared an Initial Regulatory Flexibility Analysis (IRFA) 
pursuant to section 603 of the Regulatory Flexibility Act (RFA). The 
IRFA analyzes the impacts to small entities that may be affected by the 
proposed designation and is included as appendix D of the Information 
Report (NMFS, 2023), which is available at the link provided in 
ADDRESSES, or upon request (see FOR FURTHER INFORMATION CONTACT). We 
welcome public comment on the IRFA, which is summarized below, as 
required by section 603 of the RFA.
    The IRFA uses the best available information to identify the 
potential impacts of designating critical habitat on small entities. 
However, uncertainty regarding the extent to which impacts of the 
proposed designation would be allocated between large and small 
entities complicates quantification of impacts specifically borne by 
small entities. Absent specific knowledge regarding which small 
entities may be involved in consultations with NMFS over the next ten 
years, this analysis relies on industry- and location-specific 
information on small businesses with North American Classification 
System (NAICS) codes that were identified as relevant to the major 
activity categories considered in the economic analysis and which 
operate within counties or territories that share a coastline with the 
proposed critical habitat. Activities considered in the draft economic 
report and the IRFA include in-water and coastal construction, dredging 
and disposal, water quality and discharges, fishery management, 
military activities, shipwreck and marine debris removal, scientific 
research and monitoring, aquaculture, protected area management, and 
beach nourishment/shoreline protection.
    Information presented in section 4.0 of the Economic Impact 
Analysis Report demonstrates the lack of third-party involvement in 
consultations on the effects of Federal fishery management, protected 
area management, shipwreck removal, scientific research and monitoring, 
and military activities on ESA-listed marine species within the island 
units considered for proposed coral critical habitat in the five 
jurisdictions. Unlike consultations on in-water and coastal 
construction and dredging projects, these consultations are conducted 
directly between NMFS and the Federal action agency with no third-party 
involvement. Each of these five categories of consultation is 
represented in the consultations completed in 2005-2020 that were 
reviewed for the economic impact analysis, and third parties were not 
involved in any of them. As discussed in the IRFA and section 6 
Economic Impact Analysis Report, consultations on water quality 
management include inter-agency consultations on regional water quality 
standards, which do not involve third parties, and project-specific 
consultations regarding point source water pollution, such as National 
Pollutant Discharge Elimination System (NPDES) permits issued to third 
parties in American Samoa, Guam, and CNMI. The third parties issued 
NPDES permits are either businesses or territorial or commonwealth 
governments that do not qualify as small entities. In addition, because 
no section 7 consultations on beach nourishment and shoreline 
protection projects occurred within the historical time frame selected 
for the economic impact analysis, no section 7 consultations on such 
projects were projected over the next ten years. As a result, no 
incremental costs are assigned to small entities for these activities. 
While consultations on aquaculture projects have the potential to 
involve third parties, the potential economic impacts to third parties 
are considered de minimis. Moreover, all of the historical aquaculture 
projects that resulted in consultations considered in the economic 
impact analysis were sponsored by public entities, none of which 
qualify as small entities.
    Consultations on in-water and coastal construction and dredging and 
disposal (as determined by the 4(b)(2) Economic Impact Analysis Report, 
which is appendix C of the Information Report (NMFS, 2023)), all have 
the potential to involve third parties, such as recipients of Clean 
Water Act section 404 permits. These activities were combined into one 
broad industry category that may experience impacts to small entities: 
In-Water and Coastal Construction and Dredging. NAICS industries that 
are relevant to in-water and coastal construction and dredging 
activities include:
     Water and Sewer Line and Related Structures Construction 
(NAICS 237110).
     Highway, Street, and Bridge Construction (NAICS 237310).
     Other Heavy and Civil Engineering Construction (237990).
     Dredging and Surface Cleanup (NAICS 237990).
    The IRFA relies on the estimated incremental impacts resulting from 
the proposed critical habitat designation, as described in section 6.0 
of the Economic Impact Analysis Report. To be consistent with this 
analysis, the IRFA provides low-end and high-end estimates of the 
impacts to small entities. The IRFA estimates the impacts of the 
proposed coral critical habitat in terms of the percentage of revenues 
per small entity, which ranged from 0.20 percent under the low-end 
(IRFA, table 1) to 36.9 percent under the high-end (IRFA, table 2). 
These impacts are anticipated to be borne by the small entities engaged 
in in-water and coastal construction and dredging that consult with 
NMFS regarding the listed Indo-Pacific coral species critical habitat 
in the next 10 years. Impacts are presented in the IRFA for each of the 
three U.S. Pacific jurisdictional areas where one or more of the listed 
coral species occur and where small businesses engaged in the relevant 
activities have been identified--American Samoa, Guam, and CNMI. 
According to section 6.0 of the Economic Impact Analysis Report, two or 
fewer consultations on in-water

[[Page 83664]]

and coastal construction projects are forecasted to occur in both the 
NWHI and the PRIA. However, because no businesses are located in either 
the NWHI or the PRIA, it is not possible to determine what small 
entities, if any, would be affected. In any case, given that few 
consultations are expected to occur and that these consultations are 
likely to be informal, the potential costs to small entities associated 
with in-water and coastal construction projects in the NWHI and the 
PRIA are anticipated to be negligible.
    The low-end estimate assumes no incremental project modifications 
occur because baseline permit conditions/regulations would provide 
sufficient protection to avoid adverse modification of critical 
habitat. Impacts to small entities are thus assumed to be due solely to 
the additional administrative costs of considering the potential for 
adverse effects to critical habitat during section 7 consultations. In 
addition, the low-end estimate assumes that trends in the frequency of 
informal consultations over the next 10 years will resemble those of 
the past 10 years (section 6.0 of the Economic Impact Analysis Report). 
The low-end estimate of total annualized impacts to small entities is 
$4,675 (IRFA, table 1).
    The high-end estimate of the impacts to small entities assumes that 
all future projects related to in-water and coastal construction and 
dredging will require formal consultations and that there will be 
incremental project modification costs for all these future projects 
(section 6.0 of the Economic Impact Analysis Report). In order to 
present a conservative estimate of the impacts to small entities (i.e., 
an estimate more likely to overstate impacts than understate them), the 
IRFA assumes that all project modification costs are borne by third 
parties. The high-end estimate of total annualized impacts to small 
entities is $872,331 (IRFA, table 1).
    Given the uncertainty regarding which small entities in a given 
industry will need to consult with NMFS, this analysis estimates 
impacts to small entities under two different scenarios for both the 
low-end and high-end estimates. These scenarios are intended to reflect 
the range of uncertainty regarding the number of small entities that 
may be affected by the designation and the potential impacts of 
critical habitat designation on their annual revenues.
    Under Scenario 1, the IRFA assumes that all third parties involved 
in future consultations are small entities and that incremental impacts 
for each territory or commonwealth (American Samoa, Guam, and CNMI) are 
distributed evenly across all of the entities in the respective 
territory or commonwealth. Scenario 1 accordingly reflects a high 
estimate of the number of potentially affected small entities (14 for 
both the low-end and high-end estimates) and a low estimate of the 
potential effect in terms of percent of revenue, except for American 
Samoa, where it is estimated that only one entity is conducting 
construction activities in the areas considered for critical habitat. 
The assumption under Scenario 1 is that 14 small entities will be 
involved in consultation annually reflects the forecast that 
approximately 14 consultations will occur annually on construction 
activities involving third parties. This assumes that each consultation 
on construction activities involves a unique small entity, including 1 
small entity in American Samoa, 10 small entities in Guam, and 3 small 
entities in CNMI. For the low-end estimate, this analysis anticipates 
that approximately 14 small entities will incur $4,675 in annualized 
costs under Scenario 1, including $1,244 in costs to the America Samoa-
based small entity, $281 in costs per Guam-based small entity, and $235 
in costs per CNMI-based small entity. Annualized impacts of the 
rulemaking are estimated to make up less than 1 percent of average 
annual revenues of approximately $2.36 million for each affected small 
entity.\1\ For the high-end estimate, this analysis anticipates that 14 
small entities will incur $872,331 in annualized costs under Scenario 
1, including $254,356 in costs to the America Samoa-based small entity, 
$48,953 in costs per Guam-based small entity, and $47,751 in costs per 
CNMI-based small entity. Annualized impacts of the rulemaking are 
estimated to make up 17.0 percent of average annual revenues of $1.5 
million for the American Samoa-based entity, 2.1 percent of average 
annual revenues of approximately $2.37 million for Guam-based small 
entities, and 1.9 percent of average annual revenues of $2.47 million 
for CNMI-based small entities.
---------------------------------------------------------------------------

    \1\ Average annual revenues were calculated based on company-
specific revenue data sourced from the Dun & Bradstreet Hoovers 
database.
---------------------------------------------------------------------------

    Under Scenario 2, this analysis assumes that all third parties 
participating in future consultations are small and that costs 
associated with each consultation action are borne each year by a 
single small entity within the potentially impacted construction 
industries. This method likely understates the number of small entities 
affected and overstates the likely impacts on the impacted small 
entity. For the low-end estimate, this analysis anticipates that a 
single small entity will bear $4,675 in annualized costs. These 
annualized impacts make up less than 1 percent of estimated average 
annual revenues of $2.36 million for the impacted small entity. For the 
high-end estimate, this analysis anticipates that a single small entity 
will bear $872,331 in annualized costs. These impacts represent 
approximately 37 percent of estimated average annual revenues for the 
impacted small entity.
    As explained under 4(b)(2) Economic Impact Analysis, we conclude 
that the actual economic impacts are likely to be much closer to the 
low-end scenario's projections than the high-end scenario's 
projections. In addition, economic benefits would be relatively high in 
the high-end scenario (because project modifications would provide 
better protection of coral reef ecosystems, which produce economic 
benefits), but non-existent in the low-end scenario (because there 
would be no project modifications, and thus no increased protection of 
coral reef ecosystems). Moreover, while Scenario 1 and Scenario 2 
present a range of potentially affected entities and the associated 
revenue effects, we expect the actual number of small entities affected 
and revenue effects will be somewhere in the middle. In other words, 
some subset of the small entities in American Samoa, Guam, and CNMI 
greater than 2 and up to 14 will participate in section 7 consultations 
on Indo-Pacific coral critical habitat and bear associated impacts 
annually. We conclude that the economic impacts of the proposed coral 
critical habitat are likely to be much closer to those projected by the 
low-end scenario than the high-end scenario, and also that there would 
be low economic benefits. That is, we find that the economic analysis 
and IRFA support the conclusion that the proposed coral critical 
habitat would have low economic effects on small entities.
    There are no record-keeping requirements associated with the 
rulemaking. Similarly, there are no reporting requirements.
    No Federal laws or regulations duplicate or conflict with this 
proposed rule. However, the protection of listed species and habitat 
under critical habitat may overlap other sections of the ESA. For 
instance, listing of the threatened Indo-Pacific corals under the ESA 
already requires Federal agencies to consult with NMFS to avoid 
jeopardy to the species. However, this analysis only examines the 
incremental impacts to small entities from the proposed critical 
habitat rule.
    The RFA requires consideration of alternatives to the proposed rule 
that

[[Page 83665]]

would minimize significant economic impacts to small entities. We 
considered the following alternatives when developing the proposed 
critical habitat rule.
Alternative 1: No Action Alternative
    Under the no action alternative, we would not designate critical 
habitat for the listed corals. The alternative of not designating 
critical habitat was considered in this IRFA but rejected because, in 
this case, it would violate the legal requirements of the ESA. 
Moreover, we have determined that the physical feature forming the 
basis for critical habitat designation is essential to the corals' 
conservation, and conservation for these species will not succeed 
without this feature being available. Thus, the lack of protection of 
the critical habitat feature from adverse modification could result in 
continued declines in abundance of the listed corals, and loss of 
associated economic and other values these corals provide to society, 
such as recreational and commercial fishing and diving services, and 
shoreline protection services. Small entities engaged in some coral 
reef-dependent industries would be adversely affected by the continued 
declines in the listed corals. Thus, the no action alternative is not 
necessarily a ``no cost'' alternative for small entities.
Alternative 2: Preferred Alternative
    Under this alternative, the areas designated are waters ranging 
from 0 to 10 m deep to 0 to 50 m deep in the 15 units located in 
American Samoa, Guam, CNMI, the NWHI, and the PRIA. As noted in the 
Critical Habitat Information Report, the following areas are ineligible 
for proposed critical habitat: parts of Guam, parts of Tinian all of 
Farallon de Medinilla, and all of Wake Atoll. An analysis of the costs 
and benefits of the preferred alternative designation is presented in 
appendix C of the Information Report. Relative to the no action 
alternative, this alternative will likely involve an increase in 
administrative and project modification costs for those section 7 
consultations required to avoid adverse impacts to critical habitat, 
above and beyond those required due to the corals' listing alone. We 
have determined that no categories of activities would require 
consultation, and no categories of project modifications would be 
required, in the future solely due to this rulemaking and the need to 
prevent adverse modification of critical habitat. Similarly, all 
categories of activities have similar potential to adversely impact 
corals and critical habitat, and the same project modifications would 
remedy both sets of adverse effects. However, in some areas of proposed 
coral critical habitat, there may be locations with no colonies of 
listed corals, especially after a natural disturbance event (e.g., 
coral bleaching or crown-of-thorns starfish outbreak). For future 
Federal actions that have small action areas within such locations, 
costs to small entities could occur, and would represent an incremental 
impact of this rulemaking. On the other hand, because projects with 
larger or more diffuse action areas are more likely to impact both the 
listed corals and their critical habitat, consultation and project 
modification costs associated with those projects would more likely be 
coextensive with the coral listings or another regulatory requirement. 
The preferred alternative was selected because it best implements the 
critical habitat provisions of the ESA by including the well-defined 
environmental features essential to the species' conservation, and due 
to the important conservation benefits that will result from this 
alternative relative to the no action alternative.
Alternative 3: Designating a Subset of Areas
    A third alternative was considered that would have excluded from 
designation those areas in which, on economic or national security 
bases, the benefits of exclusion outweigh the benefits of inclusion. No 
areas, other than those excluded in the Preferred Alternative on the 
basis of national security impacts, were identified where it was 
determined that the benefits of exclusion outweigh the conservation 
value of designation to the species. In addition, the public did not 
submit comments on the benefits of exclusion and inclusion in general, 
nor were comments submitted on those benefits as they relate to 
specific areas. Thus, we rejected this alternative because it would 
lessen the conservation value to the species.

Coastal Zone Management Act (16 U.S.C. 1451 et seq.)

    Under section 307(c)(1)(A) of the Coastal Zone Management Act 
(CZMA) and its implementing regulations (15 CFR part 923), each Federal 
activity within or near coastal zones that has reasonably foreseeable 
effects on any land or water use or natural resource of the coastal 
zone shall be carried out in a manner which is consistent to the 
maximum extent practicable with the enforceable policies of approved 
State coastal management programs. Upon publication of the proposed 
rule (85 FR 76262, November 27, 2020), we determined that the proposed 
designation of critical habitat for the listed corals would have no 
reasonably foreseeable effects on the enforceable policies of Guam's, 
CNMI's, and American Samoa's approved Coastal Zone Management Programs, 
and submitted our determinations to each of the responsible Territorial 
agencies.
    CNMI and Guam formally objected to our determinations on February 
12, 2021, and March 26, 2021, respectively. Both Territories stated 
that there were reasonably foreseeable coastal effects of coral 
critical habitat for several reasons, including administrative burdens, 
economic impacts, and third-party impacts. CNMI requested a consistency 
determination and identified specific enforceable policies to be 
addressed. Guam interpreted our determination as a consistency 
determination, and requested a new consistency determination that 
addressed specific enforceable policies. In response to these 
objections and concerns expressed informally by American Samoa, we held 
a meeting with the three Territorial CZM Programs (American Samoa, 
Guam, and CNMI) on July 27, 2021. We explained the basis for our 
determinations at the July meeting and scheduled follow-up meetings 
with representatives of CNMI and Guam CZM Programs to review their 
objections in detail.
    On September 2, 2021, and September 7, 2021, we held meetings with 
CNMI's and Guam's CZM Programs, respectively, and the NOAA Office of 
Coastal Management, to review the Territories' objections to our 
determinations. The Territories explained why they find that coral 
critical habitat, as proposed in 2020, would result in administrative 
burdens, economic impacts, and third-party impacts. The Territorial 
representatives stated that they believe incomplete biological and 
economic data were used in the 2020 proposed rule, resulting in the 
habitat needs of the listed corals being overstated, and the extent of 
economic impacts of critical habitat being understated in the proposed 
rule. Subsequently, the Territories requested that NMFS work with their 
experts to obtain more thorough and recent biological and economic data 
to inform the proposed coral critical habitat rule. On September 30, 
2021, and October 28, 2021, NMFS held meetings with biologists based in 
American Samoa, CNMI, Guam, and Honolulu to review records of listed 
corals in the Territories, which contributed to the development of 
appendix A in the Information Report (NMFS, 2023). On September 23, 
2021, and September 25,

[[Page 83666]]

2021, Guam and CNMI submitted letters to NMFS with updated economic 
data, which was used in section 5.1.7 of the Information Report (NMFS, 
2023).
    In making revisions to the 2020 proposed critical habitat, in 
addition to considering other public comments received, we considered 
the comments submitted by each of the Territories regarding their 
respective concerns about the proposed critical habitat. With the 
withdrawal of the 2020 proposed rule, we also withdraw the November 27, 
2020, CZMA determinations for the American Samoa, Guam, and CNMI CZM 
Programs. Consistent with the CZMA, we will determine how to proceed 
for the critical habitat now being proposed and coordinate accordingly 
with the responsible agencies in American Samoa, Guam, CNMI, and 
Hawaii.

Paperwork Reduction Act (44 U.S.C. 3501 et seq.)

    This proposed rule does not contain any new or revised collection 
of information, defined by the Paperwork Reduction Act of 1995. 
Notwithstanding any other provision of the law, no person is required 
to respond to, nor shall any person be subject to a penalty for failure 
to comply with, a collection of information subject to the requirements 
of the PRA, unless that collection of information displays a currently 
valid OMB Control Number.

Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)

    This proposed rule will not produce a Federal mandate. The 
designation of critical habitat does not impose a legally-binding duty 
on non-Federal government entities or private parties. The only 
regulatory effect is that Federal agencies must ensure that their 
actions do not destroy or adversely modify critical habitat under 
section 7 of the ESA. Non-Federal entities that receive Federal 
funding, assistance, permits, or otherwise require approval or 
authorization from a Federal agency for an action may be indirectly 
affected by the designation of critical habitat, but the Federal agency 
has the legally binding duty to avoid destruction or adverse 
modification of critical habitat.
    We do not anticipate that this proposed rule will significantly or 
uniquely affect small governments. Therefore, a Small Government Action 
Plan is not required.

Consultation and Coordination With Indian Tribal Governments (E.O. 
13175)

    The longstanding and distinctive relationship between the Federal 
and tribal governments is defined by treaties, statutes, Executive 
orders, judicial decisions, and agreements, which differentiate tribal 
governments from the other entities that deal with, or are affected by, 
the Federal Government.
    This relationship has given rise to a special Federal trust 
responsibility involving the legal responsibilities and obligations of 
the United States towards Indian Tribes and with respect to Indian 
lands, tribal trust resources, and the exercise of tribal rights. 
Pursuant to these authorities, lands have been retained by Indian 
Tribes or have been set aside for tribal use. These lands are managed 
by Indian Tribes in accordance with tribal goals and objectives within 
the framework of applicable treaties and laws. Executive Order 13175, 
Consultation and Coordination with Indian Tribal Governments, outlines 
the responsibilities of the Federal Government in matters affecting 
tribal interests. The proposed critical habitat designations for 
threatened Indo-Pacific corals are located in U.S. Pacific Islands and 
therefore do not have tribal implications in accordance with Executive 
Order 13175.

Environmental Justice and Racial Equity (E.O.s 12898, 14096, 14019, 
13985)

    The designation of critical habitat is not expected to have a 
disproportionately high effect on minority populations or low-income 
populations. The purpose of this rulemaking is to protect and conserve 
ESA-listed species through the designation of critical habitat and is 
expected to help promote a healthy environment; thus, we do not 
anticipate minority populations or low-income populations to experience 
disproportionate and adverse human health or environmental burdens. The 
designation of critical habitat is not expected to disproportionately 
affect minority populations, low-income populations, or populations 
otherwise adversely affected by persistent poverty or inequality. 
Further, it is not expected to create any barriers to opportunity for 
underserved communities.

Sec.  226.231   Critical habitat for Acropora globiceps, Acropora 
retusa, Acropora speciosa, Euphyllia paradivisa, and Isopora 
crateriformis.

    Critical habitat is designated in the following jurisdictions for 
the following species as depicted in the maps below and described in 
paragraphs (a) through (e) of this section. The maps can be viewed or 
obtained with greater resolution (available at https://www.fisheries.noaa.gov/action/proposed-rule-designate-critical-habitat-threatened-indo-pacific-corals) to enable a more precise inspection of 
the proposed critical habitat for A. globiceps, A. retusa, A. speciosa, 
E. paradivisa, and I. crateriformis.
    (a) Critical habitat locations. Critical habitat is designated for 
the following species in the following jurisdictions:

                        Table 1 to Paragraph (a)

------------------------------------------------------------------------

    (b) Critical habitat boundaries. Except as noted in paragraph (d) 
of this section, critical habitat for the five species includes all 
specific areas depicted in the maps below.
    (c) Essential feature. The feature essential to the conservation of 
A. globiceps, A. retusa, A. speciosa, E. paradivisa and I. 
crateriformis is: Sites that support the normal function of all life 
stages of the corals, including reproduction, recruitment, and 
maturation. These sites are natural, consolidated hard substrate or 
dead coral skeleton, which is free of algae and sediment at the 
appropriate scale at the point of larval settlement or fragment 
reattachment, and the associated water column. Several attributes of 
these sites determine the quality of the area and influence the value 
of the associated feature to the conservation of the species:
    (1) Substrate with presence of crevices and holes that provide 
cryptic habitat, the presence of microbial biofilms, or presence of 
crustose coralline algae;
    (2) Reefscape with no more than a thin veneer of sediment and low 
occupancy by fleshy and turf macroalgae;
    (3) Marine water with levels of temperature, aragonite saturation, 
nutrients, and water clarity that have been observed to support any 
demographic function; and
    (4) Marine water with levels of anthropogenically-introduced (from 
humans) chemical contaminants that do not preclude or inhibit any 
demographic function.
    (d) Areas not included in critical habitat. Critical habitat does 
not include the following particular areas where they overlap with the 
areas described in paragraphs (a) through (c) of this section:
    (1) Pursuant to ESA section 4(a)(3)(B)(i), all areas subject to the 
2017 Wake Island and 2019 Joint Region Marianas Integrated Natural 
Resources Management Plans;
    (2) Managed areas that do not provide the quality of substrate 
essential for the conservation of the five Indo-Pacific corals are 
defined as particular areas whose consistently disturbed nature renders 
them poor habitat for coral growth and survival over time. These 
managed areas include specific areas where the substrate has been 
disturbed by planned management authorized by local, territorial, 
State, or Federal governmental entities at the time of critical habitat 
designation, and will continue to be periodically disturbed by such 
management. Examples include, but are not necessarily limited to, 
dredged navigation channels, shipping basins, vessel berths, and active 
anchorages. A comprehensive list of managed areas is provided in 
appendix B of the Information Report (NMFS, 2023);
    (3) Existing artificial substrates including but not limited to: 
fixed and floating structures, such as aids-to-navigation (AToNs), 
seawalls, wharves, boat ramps, fishpond walls, pipes, submarine cables, 
wrecks, mooring balls, docks, aquaculture cages. A comprehensive list 
of artificial substrates is provided in appendix B of the Information 
Report (NMFS, 2023).
    (e) Critical habitat maps. The specific areas of critical habitat 
within the 16 island units for the 5 listed coral species are shown on
