Endangered and Threatened Wildlife and Plants; Endangered Status 
for Four Central Texas Salamanders and Designation of Critical Habitat

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule; reopening of comment period.

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

SUMMARY: We, the U.S. Fish and Wildlife Service, announce the reopening 
of the public comment period on the August 22, 2012, proposed listing 
and proposed designation of critical habitat for the Austin blind 
salamander, Georgetown salamander, Jollyville Plateau salamander, and 
Salado salamander under the Endangered Species Act of 1973, as amended. 
Based on additional salamander locations we identified during the 60-
day comment period, we are proposing to revise previously proposed 
critical habitat units for the Georgetown and Jollyville Plateau 
salamanders. We also announce the availability of a draft economic 
analysis of the proposed designation of critical habitat for the four 
central Texas salamanders, an amended required determinations section 
of the proposal, an amended exclusions section of the proposal, and the 
availability of a refined impervious cover analysis. We are reopening 
the comment period to allow all interested parties an opportunity to 
comment simultaneously on the original proposed rule, this revised 
proposed rule, the associated draft economic analysis, the amended 
required determinations and exclusions sections, and the refined 
impervious cover analysis. Comments previously submitted need not be 
resubmitted, as they will be fully considered in preparation of the 
final rule.
    Document Availability: You may obtain copies of the original 
proposed rule, this revised proposed rule, the draft economic analysis, 
and the refined impervious cover analysis on the Internet at https://www.regulations.gov at Docket No. FWS-R2-ES-2012-0035 or Docket No. 
FWS-R2-ES-2013-0001 or by mail from the Austin Ecological Services

SUPPLEMENTARY INFORMATION:

Public Comments

    We will accept written comments and information during this 
reopened comment period on our proposed designation of critical habitat 
for the four central Texas salamanders that was published in the 
Federal Register on August 22, 2012 (77 FR 50768), this revised 
proposed rule, our draft economic analysis (DEA) of the proposed 
designation, the amended required determinations and exclusions 
sections, and the refined impervious cover analysis. We are also 
notifying the public that we will publish two separate rules for the 
final listing determination and the final critical habitat

[[Page 5386]]

determination for the 4 central Texas salamanders. The final listing 
rule will publish under the existing Docket No. FWS-R2-ES-2012-0035 and 
the final critical habitat designation will publish under Docket No. 
FWS-R2-ES-2013-0001.
    We request that you provide comments specifically on our listing 
determination under Docket No. FWS-R2-ES-2012-0035. We will consider 
information and recommendations from all interested parties. We are 
particularly interested in comments concerning:
    (1) Biological, commercial trade, or other relevant data concerning 
any threats (or lack thereof) to these species and regulations that may 
be addressing those threats.
    (2) Additional information concerning the historical and current 
status, range, distribution, and population size of these species, 
including the locations of any additional populations of these species.
    (3) Any information on the biological or ecological requirements of 
these species, and ongoing conservation measures for these species and 
their habitats.
    (4) Land use designations including current or planned activities 
in the areas occupied by the species and possible impacts of these 
activities on the four central Texas salamanders and on proposed 
critical habitat.
    We request that you provide comments specifically on the critical 
habitat determination and related economic analysis under Docket No. 
FWS-R2-ES-2013-0001. We will consider information and recommendations 
from all interested parties. We are particularly interested in comments 
concerning:
    (5) The reasons why we should or should not designate habitat as 
``critical habitat'' under section 4 of the Act (16 U.S.C. 1531 et 
seq.) including whether there are threats to the species from human 
activity, the degree of which can be expected to increase due to the 
designation, and whether that increase in threat outweighs the benefit 
of designation, such that the designation of critical habitat may not 
be prudent.
    (6) Specific information on:
    (a) The amount and distribution of the four central Texas 
salamanders and their habitats;
    (b) What areas, that are currently occupied by these species and 
that contain features essential to their conservation, should be 
considered for critical habitat and why;
    (c) Special management considerations or protection that may be 
needed in critical habitat areas we are proposing, including managing 
for the potential effects of climate change;
    (d) What areas not occupied at the time of listing are essential 
for the conservation of these species and why;
    (e) How subterranean populations of these four salamander species 
are distributed underground; and
    (f) The interconnectedness of salamander habitats in terms of 
hydrology, and whether salamanders are able to move between sites 
through underground aquifer conduits.
    (7) Information on the projected and reasonably likely impacts of 
climate change on the four central Texas salamanders and proposed 
critical habitat.
    (8) Any probable economic, national security, or other relevant 
impacts of designating any area that may be included in the final 
critical habitat designation; in particular, we seek information on any 
impacts on small entities, and the benefits of including or excluding 
areas that are subject to these impacts.
    (9) Whether any specific areas we are proposing for critical 
habitat designation should be considered for exclusion under section 
4(b)(2) of the Act, and whether the benefits of potentially excluding 
any specific area outweigh the benefits of including that area under 
section 4(b)(2) of the Act, in particular for those areas that may 
benefit from the Buttercup Habitat Conservation Plan (HCP), Lakeline 
HCP, and Barton Springs Pool HCP.
    (10) Whether we could improve or modify our approach to designating 
critical habitat in any way to provide for greater public participation 
and understanding, or to better accommodate public concerns and 
comments.
    If you submitted comments or information on the proposed rule (77 
FR 50768) during the initial comment period from August 22, 2012, to 
October 22, 2012, please do not resubmit them. We will incorporate them 
into the public record as part of this comment period, and we will 
fully consider them in the preparation of our final determination. Our 
final determination concerning critical habitat will take into 
consideration all written comments and any additional information we 
receive during both comment periods. On the basis of public comments, 
we may, during the development of our final determination, find that 
areas proposed are not essential, are appropriate for exclusion under 
section 4(b)(2) of the Act, or are not appropriate for exclusion.
    You may submit your comments and materials concerning the proposed 
rule or DEA by one of the methods listed in the ADDRESSES section. We 
request that you send comments only by the methods described in the 
ADDRESSES section.
    If you submit a comment via https://www.regulations.gov, your entire 
comment--including any personal identifying information--will be posted 
on the Web site. We will post all hardcopy comments on https://www.regulations.gov as well. If you submit a hardcopy comment that 
includes personal identifying information, you may request at the top 
of your document that we withhold this information from public review. 
However, we cannot guarantee that we will be able to do so.
    Comments and materials we receive, as well as supporting 
documentation we used in preparing the proposed rule and DEA, will be 
available for public inspection on https://www.regulations.gov at Docket 
No. FWS-R2-ES-2012-0035 and Docket No. FWS-R2-ES-2013-0001, or by 
appointment, during normal business hours, at the U.S. Fish and 
Wildlife Service, Austin Ecological Services Field Office (see FOR 
FURTHER INFORMATION CONTACT). You may obtain copies of the proposed 
rule and the DEA on the Internet at https://www.regulations.gov at 
Docket Number FWS-R2-ES-2012-0035 or Docket No. FWS-R2-ES-2013-0001, or 
by mail from the Austin Ecological Services Field Office (see FOR 
FURTHER INFORMATION CONTACT section).

Background

    It is our intent to discuss only those topics directly relevant to 
the listing and designation of critical habitat for the four central 
Texas salamanders in this document. For more information on the four 
central Texas salamanders, their habitat, or previous Federal actions, 
refer to the proposed listing rule published in the Federal Register on 
August 22, 2012 (77 FR 50768), which is available online at https://www.regulations.gov (at Docket Number FWS-R2-ES-2012-0035 or Docket No. 
FWS-R2-ES-2013-0001) or from the Austin Ecological Services Field 
Office (see FOR FURTHER INFORMATION CONTACT).
    On August 22, 2012, we published a proposed rule to designate 
critical habitat for the four central Texas salamanders (77 FR 50768). 
We proposed to designate approximately 5,983 acres (ac) (2,440 hectares 
(ha)) in 52 units located in Travis, Williamson, and Bell Counties, 
Texas, as critical habitat. That proposal had a 60-day comment period, 
ending October 22, 2012. We held a public meeting and

[[Page 5387]]

hearing in Round Rock, Texas, on September 5, 2012, and a second public 
meeting and hearing in Austin, Texas, on September 6, 2012.

Refined Impervious Cover Analysis

    In our August 22, 2012, proposed rule (77 FR 50768), under Factor 
A. The Present or Threatened Destruction, Modification, or Curtailment 
of Its Habitat or Range, we used the best available information at that 
time to calculate the extent and magnitude of impervious cover within 
the watersheds occupied by the four central Texas salamander species. 
Impervious cover degrades stream habitat in three ways: (1) Introducing 
and concentrating contaminants in surface runoff, (2) increasing the 
rate at which sediment is deposited into a stream, and (3) altering the 
natural flow regime of streams. We used an impervious cover analysis in 
the proposed rule (77 FR 50768) to help inform our analysis of the 
threat of urbanization to the four central Texas salamanders. This 
refined analysis will help inform the final listing determination of 
the four central Texas salamanders.
    For the August 22, 2012, impervious cover analysis, we used the 
national Watershed Boundary Dataset to delineate 15 watersheds occupied 
by the four central Texas salamander species. Although the data for 
this impervious cover analysis were derived using the finest scale 
hydrologic units readily available at that time in the Watershed 
Boundary Dataset, they were too large to offer any reference to the 
location of salamander-occupied spring sites in relation to the 
location of impervious cover within the watersheds. Because this 
analysis did not take into account whether the salamander sites are 
found upstream or downstream of impervious surfaces associated with 
developed areas, our previous impervious cover analysis within each 
watershed may not necessarily be an indicator of how much impervious 
cover is actually impacting water quality at known salamander sites.
    Since the publication of our August 22, 2012, proposed rule (77 FR 
50768), we obtained new information that has allowed us to refine our 
impervious cover analysis and determine where impervious cover is in 
relation to known salamander sites. This refined analysis is based on 
the National Hydrography Dataset Plus watershed dataset, which is a 
nationally consistent watershed dataset developed by the U.S. 
Environmental Protection Agency and U.S. Geological Survey. The 
National Hydrography Dataset Plus integrates the National Hydrography 
Dataset with the National Elevation Dataset and the Watershed Boundary 
Dataset to locate and identify smaller watersheds than can be found in 
the Watershed Boundary Dataset itself. We then used ESRI software to 
create an aspect map and a set of 5-feet (ft) (2-meter (m)) contour 
lines to help guide the identification and mapping of even smaller 
watersheds that specifically drain into individual salamander spring 
sites (springsheds). In our refined analysis, we calculated impervious 
cover within 113 springsheds occupied by the 4 central Texas salamander 
species. We also compared the results of our refined impervious cover 
analysis with two additional impervious cover analyses conducted by 
SWCA Environmental Consultants (SWCA) and the City of Austin (COA).
    Increases in impervious cover cause measurable stream degradation 
(Klein 1979, p. 959; Bannerman et al. 1993, pp. 251-254, 256-258; 
Center for Watershed Protection 2003, p. 91; Coles et al. 2012, p. 4). 
The best available scientific literature indicates that detrimental 
effects to salamander habitat are likely to begin having significant 
negative impact on salamander populations at 10 percent impervious 
cover in a springshed. This is in agreement with Bowles et al. (2006, 
pp. 113, 117-118), which found lower Jollyville Plateau salamander 
densities in watersheds with more than 10 percent impervious cover. 
Based upon our refined impervious cover analysis, we have found that 
the Jollyville Plateau salamander has the highest number of springsheds 
with habitat degrading levels of impervious cover (57 out of 91). 
Results from COA data are similar to our findings, and suggest that an 
additional three Jollyville Plateau salamander sites have habitat-
degrading levels of impervious cover. Conversely, our data show that 
the watersheds encompassing Georgetown and Salado salamander habitat 
are relatively low in impervious cover. However, the high human 
population growth rate expected in Williamson and Bell Counties 
indicates that impervious cover has the potential of approaching levels 
that could negatively impact the Georgetown and Salado salamanders' 
continued existence. In addition, SWCA's analysis demonstrates that 
recent development and quarry creation in some Georgetown salamander 
springsheds may have already increased impervious cover past the 
threshold of habitat degradation.

impervious cover analysis, go to https://www.regulations.gov and search 
for Docket Number FWS-R2-ES-2012-0035, or you may obtain copies by mail 
from the Austin Ecological Field Services Office (see FOR FURTHER 
INFORMATION CONTACT).

Critical Habitat

    Section 3 of the Act defines critical habitat as the specific areas 
within the geographical area occupied by a species, at the time it is 
listed in accordance with the Act, on which are found those physical or 
biological features essential to the conservation of the species and 
that may require special management considerations or protection, and 
specific areas outside the geographical area occupied by a species at 
the time it is listed, upon a determination that such areas are 
essential for the conservation of the species. If the proposed rule is 
made final, section 7 of the Act will prohibit destruction or adverse 
modification of critical habitat by any activity funded, authorized, or 
carried out by any Federal agency. Federal agencies proposing actions 
affecting critical habitat must consult with us on the effects of their 
proposed actions, under section 7(a)(2) of the Act.

Consideration of Impacts Under Section 4(b)(2) of the Act

    Section 4(b)(2) of the Act requires that we designate or revise 
critical habitat based upon the best scientific data available, after 
taking into consideration the economic impact, impact on national 
security, or any other relevant impact of specifying any particular 
area as critical habitat. We may exclude an area from critical habitat 
if we determine that the benefits of excluding the area outweigh the 
benefits of including the area as critical habitat, provided such 
exclusion will not result in the extinction of the species.
    When considering the benefits of inclusion for an area, we consider 
the additional regulatory benefits that area would receive from the 
protection from adverse modification or destruction as a result of 
actions with a Federal nexus (activities conducted, funded, permitted, 
or authorized by Federal agencies), the educational benefits of mapping 
areas containing essential features that aid in the recovery of the 
listed species, and any benefits that may result from designation due 
to State or Federal laws that may apply to critical habitat.
    When considering the benefits of exclusion, we consider, among 
other things, whether exclusion of a specific area is likely to result 
in conservation; the continuation, strengthening, or encouragement of 
partnerships; or implementation of a management plan. In the case of 
the four central Texas

[[Page 5388]]

salamanders, the benefits of critical habitat include public awareness 
of the presence of the species and the importance of habitat 
protection, and, where a Federal nexus exists, increased habitat 
protection for the four central Texas salamanders due to protection 
from adverse modification or destruction of critical habitat. In 
practice, situations with a Federal nexus exist primarily on Federal 
lands or for projects undertaken by Federal agencies.
    The final decision on whether to exclude any areas will be based on 
the best scientific data available at the time of the final 
designation, including information obtained during the comment period 
and information about the economic impact of designation. Accordingly, 
we have prepared a DEA concerning the proposed critical habitat 
designation, which is available for review (see https://www.regulations.gov at Docket Number FWS-R2-ES-2013-0001, or contact 
the Austin Ecological Services Field Office (see FOR FURTHER 
INFORMATION CONTACT)) and comment (see ADDRESSES).

Changes From Previously Proposed Critical Habitat

    In this document, we are notifying the public of changes to the 
proposed critical habitat designation. Based on additional information 
we received during the August 22, 2012, to October 22, 2012, comment 
period on the proposed rule, in this document we propose to revise 
Units 2, 3, 5, 8, and 12 for the Georgetown salamander, and Units 3, 4, 
5, 9, 10, 17, 22, 23, and 28 for the Jollyville Plateau salamander. All 
other areas proposed on August 22, 2012, remain as proposed at 77 FR 
50768 for designation as critical habitat.
    The proposed revisions for the Georgetown salamander critical 
habitat Units 2, 3, 5, 8, and 12 are adjustments in the locations of 
these units based on clarifying information we received since the 
proposed rule was published. Proposed Unit 2 is located 130 ft (40 m) 
southeast from the location we gave in the August 22, 2012, proposed 
rule. Proposed Unit 3 is located 2,350 ft (715 m) to the northeast of 
the location we gave in the August 22, 2012, proposed rule. Unit 5 is 
located 165 ft (50 m) to the southwest from the location we gave in the 
August 22, 2012, proposed rule. In Unit 8, the Knight Spring location 
is located 165 ft (50 m) west of the location we gave in the August 22, 
2012, proposed rule. Lastly, Unit 12 is located 200 ft (60 m) to the 
northwest of the location we gave in the August 22, 2012, proposed 
rule. The total number of proposed critical habitat units, 
landownership by type, and size of the proposed critical habitat units 
remain the same for the Georgetown salamander as provided in the August 
22, 2012, proposed rule.
    For the Jollyville Plateau Salamander, we received additional 
locations where salamanders are known to occur that we are using to 
revise proposed Units 3, 4, 5, 9, 10, 17, 22, 23, and 28. Based on 
eight new locations, we are combining proposed Units 3, 4, and 5 into 
one proposed critical habitat unit, Unit 3 (Buttercup Creek Unit). Unit 
3 now contains a total of 699 ac (283 ha) of proposed critical habitat. 
In proposed Unit 9, we are proposing to add one additional spring 
location (Wheless 2), which results in an increase in the proposed 
unit's area increasing from 135 ac (55 ha) to 145 ac (59 ha). In 
proposed Unit 10, we are proposing to add two new locations, Blizzard 2 
and 3, which increases the size of this proposed unit from 68 ac (28 
ha) to 88 ac (36 ha). In proposed Unit 17, we are proposing to add 
eight new locations, which changes the size of this proposed unit from 
1,157 ac (468 ha) to 1,198 ac (485 ha). Based on five new additional 
locations, we are proposing to combine previously proposed Units 22 and 
23 into one unit, Unit 22 (Sylvia Spring Area Unit). Unit 22 now 
contains a total of 238 ac (96 ha) of proposed critical habitat. In 
proposed Unit 28, we are proposing to add one new location called 
Stillhouse Hollow, but the proposed addition of this location does not 
result in a change to the size of the unit. In total for the Jollyville 
Plateau salamander, we previously proposed 4,460 ac (1,816 ha) of 
critical habitat in 33 units, which we have revised based on new 
locations, and we are now proposing 4,934 ac (1,997 ha) in 30 units.

Proposed Critical Habitat Designation

    In Tables 1 and 2 below, we present the revised proposed critical 
habitat units for the Georgetown and Jollyville Plateau salamanders. 
Also, we provide revised unit descriptions for Jollyville Plateau 
salamander Units 3 and 22. Further detail for both surface and 
subsurface critical habitat components may be found in the August 22, 
2012, proposed rule (77 FR 50768).

Jollyville Plateau Salamander

Unit 3: Buttercup Creek Unit
    Unit 3 consists of 699 ac (283 ha) of City of Austin, State of 
Texas, and private land in southern Williamson County and northern 
Travis County, Texas. The unit is located just east of Anderson Mill 
Road. Lakeline Boulevard, a major thoroughfare, crosses the northeast 
area of the unit. The unit is mostly covered with residential property. 
A quarry is in the northwestern edge of the unit. An undeveloped area 
of parks and setbacks is in the south central and southeastern part of 
the unit. This unit contains 13 caves: Hunter's Lane Cave, Testudo 
Tube, Bluewater Cave 1, Bluewater Cave 2, TWASA Cave, 
Illex Cave, Buttercup Creek Cave, Godzilla Cave, Hideaway Cave, 
Salamander Squeeze Cave, Treehouse Cave, Whitewater Cave, and Flea 
Cave, which are all occupied by the Jollyville Plateau salamander. All 
caves except Hunter's Lane Cave, Testudo Tube, Bluewater Cave 
1, and Bluewater Cave 2 are located in preserves set 
up as mitigation property under the Buttercup habitat conservation plan 
(HCP), which is held by the City of Austin. This HCP covers adverse 
impacts to the endangered Tooth Cave ground beetle (Rhadine 
persephone). Although the salamander is not covered under the Buttercup 
HCP, the protection afforded these caves by the HCP provides some 
benefit for the species.
    The Lakeline Mall HCP covers the Testudu Tube Cave location. As 
part of the mitigation for the Lakeline Mall HCP, Testudo Tube Cave 
must be protected and managed in perpetuity. Hunter's Lane Cave is 
located in Discovery Well Preserve, which is State land leased to the 
City of Cedar Park. This preserve was purchased by the Texas Department 
of Transportation (formally Texas Turnpike Authority Division) as 
mitigation for impacts to the Tooth Cave ground beetle from the 
construction of the U.S. Highway 183 alternate highway project. The 
mitigation actions from these HCPs and highway project provide some 
benefit to the Jollyville Plateau salamander by establishing preserve 
areas that limit development near the caves. Bluewater Cave 1 
and Bluewater Cave 2 are located on public land within older 
development. All caves in this unit except Bluewater Cave 1 
and Hunter's Lane Cave contain the Tooth Cave ground beetle. The unit 
contains all the primary constituent elements essential for the 
conservation of the Jollyville Plateau salamander.
    The unit requires special management because of the potential for 
groundwater pollution from current and future development in the 
watershed, potential for vandalism, and depletion of groundwater (see 
Special Management Considerations or Protection section of the proposed 
listing and critical habitat rule (77 FR 50768; August 22, 2012)).
    The proposed critical habitat designation includes the caves. The 
unit was further delineated by drawing a circle with a radius of 980 ft 
(300 m) around the cave, representing the extent of the subterranean 
critical habitat.
Unit 22: Sylvia Spring Area Unit
    Unit 22 consists of 238 ac (96 ha) of private, City of Austin, and 
Williamson County land in northern Travis County and southwestern 
Williamson County, Texas. The unit is located east of the intersection 
of Callanish Park Drive and Westerkirk Drive and north of the 
intersection of Spicewood Springs Road and Yaupon Drive. Spicewood 
Springs Road crosses the unit from southwest to east. Residential and 
commercial

[[Page 5390]]

development is found in most of the unit. An undeveloped stream 
corridor crosses the unit from east to west. This unit contains Small 
Sylvia Spring, Sylvia Spring Area 2, Sylvia Spring Area 3, Sylvia 
Spring Area 4, Spicewood Valley Park Spring, Tanglewood Spring, 
Tanglewood 2, and Tanglewood 3, which are occupied by the Jollyville 
Plateau salamander. Small Sylvia Spring, Sylvia Spring Area 2, Sylvia 
Spring Area 3, Sylvia Spring Area 4, and Spicewood Valley Park Spring 
are located on an unnamed tributary to Tanglewood Creek. Tanglewood 
Spring, Tanglewood 2, and Tanglewood 3 are located on Tanglewood Creek, 
a tributary to Bull Creek. The unit contains the primary constituent 
elements essential for the conservation of the species.
    The unit requires special management because of the potential for 
groundwater pollution from current and future development in the 
watershed, potential for vandalism, and depletion of groundwater (see 
Special Management Considerations or Protection section of the proposed 
listing and critical habitat rule (77 FR 50768; August 22, 2012)).
    The proposed designation includes the spring outlets and outflow up 
to the high water line and 160 ft (50 m) of downstream habitat. The 
unit was further delineated by drawing a circle with a radius of 980 ft 
(300 m) around the springs, representing the extent of the subterranean 
critical habitat. We joined the edges of the resulting circles.

Amended Exclusions

    In our August 22, 2012, proposed rule (77 FR 50768), we stated that 
we would evaluate whether certain lands in the proposed critical 
habitat designation for Jollyville Plateau salamander in the Bull Creek 
3 Unit (Unit 19 for the Jollyville Plateau salamander) are appropriate 
for exclusion from the final designation under section 4(b)(2) of the 
Act. We are now adding the following land in the proposed critical 
habitat for the Austin blind salamander to the list of areas we are 
considering for exclusion from the final critical habitat designation.

Unit 1: Barton Springs Unit...............  Barton Springs Pool HCP.....      120 ac (49 ha)        22 ac (9 ha)
----------------------------------------------------------------------------------------------------------------

    Under section 4(b)(2) of the Act, we consider any other relevant 
impacts, in addition to economic impacts and impacts on national 
security. We consider a number of factors including whether the 
landowners have developed any HCPs or other management plans for the 
area, or whether there are conservation partnerships that would be 
encouraged by designation of, or exclusion from, critical habitat. In 
addition, we look at any tribal issues, and consider the government-to-
government relationship of the United States with tribal entities.

Land and Resource Management Plans, Conservation Plans, or Agreements 
Based on Conservation Partnerships

    We consider a current land management or conservation plan (HCP as 
well as other types) to provide adequate management or protection if it 
meets the following criteria:
    (1) The plan is complete and provides the same or better level of 
protection from adverse modification or destruction than that provided 
through a consultation under section 7 of the Act;
    (2) There is a reasonable expectation that the conservation 
management strategies and actions will be implemented for the 
foreseeable future, based on past practices, written guidance, or 
regulations; and
    (3) The plan provides conservation strategies and measures 
consistent with currently accepted principles of conservation biology.
Barton Springs Pool Habitat Conservation Plan
    We are considering the exclusion of non-Federal lands covered by 
the Barton Springs Pool HCP. We are requesting comments on the benefit 
to the Austin blind salamander from this HCP.
    The Permittee (City of Austin) is authorized to take (kill, harm, 
or harass) the endangered Barton Springs salamander (Eurycea sosorum) 
at the four spring sites collectively known as Barton Springs, 
incidental to activities for the operation and maintanence of the pool 
and adjacent spring sites as described in the original Permittee's 
(City of Austin) application and habitat conservation plan. The Barton 
Springs Pool HCP currently requires the following measures for the 
mitigation of incidental take of the Barton Springs salamander during 
routine pool maintanence and cleaning. These measures are also being 
applied to the Austin blind salamander as if it were a listed species:
     Cleaning of the shallow end without lowering the entire 
pool.
     Visual searching for stranded salamanders after lowering 
the pool.
     Lowering of the beach.
     Cleaning of the fissures, the new ``beach'' habitat, and 
adjacent springs using low-pressure hoses.
     Installation of an underwater walkway and a stainless 
steel railing in the deep end.
     Maintenance of 11,000 square feet (1,022 square meters) of 
``beach'' habitat.
     Restricting public access to Eliza and Sunken Garden (Old 
Mill) Springs.
     Daily inspections of all spring sites for vandalism, 
habitat disturbance, and exotic species.
     Implementation of a program to increase public awareness 
and community support for the salamanders.
     Establishment of a conservation and research fund for the 
salamanders.
     Reduce loadings of contaminants into Barton Springs from 
current development and activities in the Barton Springs Zone of the 
Edwards Aquifer.
     Creation of a captive breeding facility for the Barton 
Springs and Austin blind salamanders.
    The measures described above will provide conservation benefits to 
the Austin blind salamander by minimizing the death of individuals 
during routine pool maintenance, preventing habitat disturbance from 
vandalism, and maintaining water quality in the springs.

Draft Economic Analysis

    The purpose of the DEA is to identify and analyze the potential 
economic impacts associated with the proposed critical habitat 
designation for the four central Texas salamanders. The DEA separates 
conservation measures into two distinct categories according to 
``without critical habitat'' and ``with critical habitat'' scenarios. 
The ``without

[[Page 5391]]

critical habitat'' scenario represents the baseline for the analysis, 
considering protections otherwise afforded to the four central Texas 
salamanders (e.g., under the Federal listing and other Federal, State, 
and local regulations). The ``with critical habitat'' scenario 
describes the incremental impacts specifically due to designation of 
critical habitat for the species. In other words, these incremental 
conservation measures and associated economic impacts would not occur 
but for the designation. Conservation measures implemented under the 
baseline (without critical habitat) scenario are described 
qualitatively within the DEA, but economic impacts associated with 
these measures are not quantified. Economic impacts are only quantified 
for conservation measures implemented specifically due to the 
designation of critical habitat (i.e., incremental impacts). For a 
further description of the methodology of the analysis, see Chapter 2, 
``FRAMEWORK FOR THE ANALYSIS'' of the DEA.
    The DEA provides estimated costs of the foreseeable potential 
economic impacts of the proposed critical habitat designation for the 
four central Texas salamanders over the next 23 years, which was 
determined to be the appropriate period for analysis, because limited 
planning information is available for most activities to forecast 
activity levels for projects beyond a 23-year timeframe. It identifies 
potential incremental costs as a result of the proposed critical 
habitat designation; these are those costs attributed to critical 
habitat over and above those baseline costs attributed to listing.
    The DEA quantifies economic impacts of the four central Texas 
salamanders conservation efforts associated with the following 
categories of activity: (1) Development, (2) water management 
activities, (3) transportation projects, (4) utility projects, (5) 
mining, and (6) livestock grazing. Economic impacts are estimated for 
development, transportation, mining, and species and habitat management 
activities. No impacts are forecast for water management activities, 
utility projects, and livestock grazing activities. For these 
activities, no projects with a Federal nexus were identified within the 
study area.
    Total present value impacts anticipated to result from the 
designation of all areas proposed as salamander critical habitat are 
approximately $29 million over 23 years. All incremental costs are 
administrative in nature and result from the consideration of adverse 
modification in section 7 consultations and re-initiation of 
consultations for existing management plans. Proposed Unit 1 for the 
Austin blind salamander and proposed Unit 32 for the Jollyville Plateau 
salamander are likely to experience the greatest incremental impacts. 
Impacts in proposed Unit 1 for the Austin blind salamander are 
estimated at $3.7 million in present value terms (13.0 percent of total 
present value impacts), and result from a portion of the consultation 
associated with the Mopac Expressway and approximately 21 consultations 
annually on development projects withinproposed Unit 1 itself and the 
Lake Austin watershed. Impacts in proposed Unit 32 for the Jollyville 
Plateau salamander are estimated at $2.9 million in present value terms 
(10.1 percent of total present value impacts), and result from a 
portion of the consultations associated with three transportation 
projects and approximately 17 consultations annually on development 
projects within proposed Unit 32 itself and the Walnut Creek watershed. 
Overall, consultations associated with development activities account 
for approximately 98.8 percent of the incremental impacts in this 
analysis.
    As we stated earlier, we are soliciting data and comments from the 
public on the DEA, as well as all aspects of the proposed rule and our 
amended required determinations. We may revise the proposed rule or 
supporting documents to incorporate or address information we receive 
during the public comment period. In particular, we may exclude an area 
from critical habitat if we determine that the benefits of excluding 
the area outweigh the benefits of including the area, provided the 
exclusion will not result in the extinction of this species.

Required Determinations--Amended

    In our August 22, 2012, proposed rule (77 FR 50768), we indicated 
that we would defer our determination of compliance with several 
statutes and executive orders until the information concerning 
potential economic impacts of the designation and potential effects on 
landowners and stakeholders became available in the DEA. We have now 
made use of the DEA data to make these determinations. In this 
document, we affirm the information in our proposed rule concerning 
Executive Order (E.O.) 12866 (Regulatory Planning and Review), E.O. 
12630 (Takings), E.O. 13132 (Federalism), E.O. 12988 (Civil Justice 
Reform), E.O. 13211 (Energy, Supply, Distribution, and Use), the 
Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.), the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.), the National 
Environmental Policy Act (42 U.S.C. 4321 et seq.), and the President's 
memorandum of April 29, 1994, ``Government-to-Government Relations with 
Native American Tribal Governments'' (59 FR 22951). However, based on 
the DEA data, we are amending our required determinations concerning 
the Regulatory Flexibility Act (5 U.S.C. 601 et seq.) and E.O. 12630 
(Takings).

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

    Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.), 
as amended by the Small Business Regulatory Enforcement Fairness Act of 
1996 (SBREFA; 5 U.S.C. 801 et seq.), whenever an agency must publish a 
notice of rulemaking for any proposed or final rule, it must prepare 
and make available for public comment a regulatory flexibility analysis 
that describes the effects of the rule on small entities (i.e., small 
businesses, small organizations, and small government jurisdictions). 
However, no regulatory flexibility analysis is required if the head of 
the agency certifies the rule will not have a significant economic 
impact on a substantial number of small entities. The SBREFA amended 
the RFA to require Federal agencies to provide a certification 
statement of the factual basis for certifying that the rule will not 
have a significant economic impact on a substantial number of small 
entities. Based on our DEA of the proposed designation, we provide our 
analysis for determining whether the proposed rule would result in a 
significant economic impact on a substantial number of small entities. 
Based on comments we receive, we may revise this determination as part 
of our final rulemaking.
    According to the Small Business Administration, small entities 
include small organizations such as independent nonprofit 
organizations; small governmental jurisdictions, including school 
boards and city and town governments that serve fewer than 50,000 
residents; and small businesses (13 CFR 121.201). Small businesses 
include manufacturing and mining concerns with fewer than 500 
employees, wholesale trade entities with fewer than 100 employees, 
retail and service businesses with less than $5 million in annual 
sales, general and heavy construction businesses with less than $27.5 
million in annual business, special trade contractors doing less than 
$11.5 million in annual business, and agricultural businesses with 
annual sales less than $750,000. To determine if potential economic 
impacts to these

[[Page 5392]]

small entities are significant, we considered the types of activities 
that might trigger regulatory impacts under this designation as well as 
types of project modifications that may result. In general, the term 
``significant economic impact'' is meant to apply to a typical small 
business firm's business operations.
    To determine if the proposed designation of critical habitat for 
the four central Texas salamanders would affect a substantial number of 
small entities, we considered the number of small entities affected 
within particular types of economic activities, such as development, 
transportation, and mining activities as well as re-initiated 
programmatic consultations for five existing conservation plans. In 
order to determine whether it is appropriate for our agency to certify 
that this proposed rule would not have a significant economic impact on 
a substantial number of small entities, we considered each industry or 
category individually. In estimating the numbers of small entities 
potentially affected, we also considered whether their activities have 
any Federal involvement. Critical habitat designation will not affect 
activities that do not have any Federal involvement; designation of 
critical habitat only affects activities conducted, funded, permitted, 
or authorized by Federal agencies. In areas where the four central 
Texas salamanders are present, Federal agencies already are required to 
consult with us under section 7 of the Act on activities they fund, 
permit, or implement that may affect the species. If we finalize this 
proposed critical habitat designation, consultations to avoid the 
destruction or adverse modification of critical habitat would be 
incorporated into the existing consultation process.
    In the DEA, we evaluated the potential economic effects on small 
entities resulting from implementation of conservation actions related 
to the proposed designation of critical habitat for the four central 
Texas salamanders. Impacts to transportation activities are expected to 
be incurred largely by Federal and State agencies. These entities are 
not considered small. Also, re-initiations of consultations regarding 
the Balcones Canyonlands Preserve, Buttercup Creek HCP, Four Points 
HCP, Lakeline Mall HCP, and Williamson County Regional HCP are not 
anticipated to involve small entities. However, incremental impacts 
associated with residential and commercial development and surface 
mining may be borne by small entities. In regards to development and 
assuming the average small entity has annual revenues of approximately 
$4.6 million, the per-entity cost to participate in a consultation 
represents approximately 0.02 percent of annual revenues if each 
consultation is undertaken by a different small entity. If all 
consultations occurring in a given year (approximately 163) are 
undertaken by the same developer, then the cost to participate in these 
consultations represents approximately 3.1 percent of annual revenues. 
In regards to mining, there are four small businesses engaged in 
limestone mining, and we anticipate that two of these small entities 
could incur incremental administrative costs as a result of a critical 
habitat designation. Assuming the average small entity has annual 
revenues of approximately $10 million, the per-entity cost to 
participate in a consultation represents approximately less than 0.01 
percent of annual revenues. Even in the event that a single small 
entity bears third-party costs for both consultations in a single year, 
the total impact represents less than 0.02 percent of annual revenues. 
Overall, we do not believe that, if made final, the designation of 
critical habitat for the four central Texas salamanders will have a 
significant impact to the small business sector. Please refer to the 
DEA of the proposed critical habitat designation for a more detailed 
discussion of potential economic impacts.
    The Service's current understanding of recent case law is that 
Federal agencies are only required to evaluate the potential impacts of 
rulemaking on those entities directly regulated by the rulemaking; 
therefore, they are not required to evaluate the potential impacts to 
those entities not directly regulated. The designation of critical 
habitat for an endangered or threatened species only has a regulatory 
effect where a Federal action agency is involved in a particular action 
that may affect the designated critical habitat. Under these 
circumstances, only the Federal action agency is directly regulated by 
the designation, and, therefore, consistent with the Service's current 
interpretation of RFA and recent case law, the Service may limit its 
evaluation of the potential impacts to those identified for Federal 
action agencies. Under this interpretation, there is no requirement 
under the RFA to evaluate the potential impacts to entities not 
directly regulated, such as small businesses. However, Executive Orders 
12866 and 13563 direct Federal agencies to assess costs and benefits of 
available regulatory alternatives in quantitative (to the extent 
feasible) and qualitative terms. Consequently, it is the current 
practice of the Service to assess to the extent practicable these 
potential impacts, if sufficient data are available, whether or not 
this analysis is believed by the Service to be strictly required by the 
RFA. In other words, while the effects analysis required under the RFA 
is limited to entities directly regulated by the rulemaking, the 
effects analysis under the Act, consistent with the E.O. regulatory 
analysis requirements, can take into consideration impacts to both 
directly and indirectly impacted entities, where practicable and 
reasonable.
    In summary, we have considered whether the proposed designation 
would result in a significant economic impact on a substantial number 
of small entities. Information for this analysis was gathered from the 
Small Business Administration, stakeholders, and the Service. For the 
above reasons and based on currently available information, we certify 
that, if promulgated, the proposed critical habitat designation will 
not have a significant economic impact on a substantial number of small 
business entities. Therefore, an initial regulatory flexibility 
analysis is not required.

Takings--Executive Order 12630

    In accordance with Executive Order 12630 (Government Actions and 
Interference with Constitutionally Protected Private Property Rights), 
we have analyzed the potential takings implications of designating 
critical habitat for the four central Texas salamanders in a takings 
implications assessment. As discussed above, the designation of 
critical habitat affects only Federal actions. Although private parties 
that receive Federal funding, assistance, or 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 squarely on the Federal agency. The economic analysis found that 
no significant ecomonic impacts are likely to result from the 
designation of critical habitat for the four central Texas salamanders. 
Because the Act's critical habitat protection requirements apply only 
to Federal agency actions, few conflicts between critical habitat and 
private property rights should result from this designation. Based on 
information contained in the economic analysis assessment and described 
within this document, it is not likely that economic impacts to a 
property owner would be of a sufficient magnitude to support a

[[Page 5393]]

takings action. Therefore, the takings implications assessment 
concludes that this designation of critical habitat for the four 
central Texas salamanders does not pose significant takings 
implications for lands within or affected by the designation.
