Download as PDF 50430 Federal Register / Vol. 81, No. 147 / Monday, August 1, 2016 / Proposed Rules consistent with the NAAQS promulgated by EPA in 2006.4 iii. O3 On July 18, 1997, EPA revoked the 1hour primary NAAQS for O3. See 62 FR 38856. On March 27, 2008, EPA promulgated a new 8-hour primary and secondary NAAQS for O3 at a level of 0.075 parts per million (ppm), based on an annual fourth-highest daily maximum 8-hr concentration averaged over three years. See 73 FR 16483. Accordingly, in the May 3, 2012, SIP submission, Jefferson County revised Regulation 3.01 to update its air quality standards for O3 to be consistent with the NAAQS promulgated by EPA in 2008. iv. NO2 On February 9, 2010, EPA promulgated a new 1-hour primary NAAQS for NO2 at a level of 100 parts per billion (ppb), based on a 3-year average of the 98th percentile of the yearly distribution of 1-hour daily maximum concentrations. See 75 FR 6474. Accordingly, in the May 3, 2012, SIP submission, Jefferson County revised Regulation 3.01 to update its primary air quality standard for NO2 to be consistent with the NAAQS promulgated by EPA in 2010. sradovich on DSK3GMQ082PROD with PROPOSALS v. SO2 On June 22, 2010, EPA promulgated a revised primary SO2 NAAQS to an hourly standard of 75 ppb, based on a 3-year average of the annual 99th percentile of 1-hour daily maximum concentrations, and revoked the 24-hour SO2 NAAQS. See 75 FR 35520. Accordingly, in the May 3, 2012, SIP submission, Jefferson County revised Regulation 3.01 to update its primary air quality standards for SO2 to be consistent with the NAAQS promulgated by EPA in 2010. EPA has reviewed the revisions to Regulation 3.01 in the May 3, 2012, SIP submission, including the NAAQS updates for Pb, particulate matter, O3, NO2, and SO2, and has made the preliminary determination that these changes are consistent with the CAA. III. Incorporation by Reference In this rule, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with 4 On January 15, 2013, EPA revised the primary annual PM2.5 NAAQS to 12 mg/m3, based on annual mean PM2.5 concentrations averaged over three years. See 78 FR 3086. Since Jefferson County’s May 3, 2012, submission preceded EPA’s promulgation of the new annual standard, an update reflecting the new NAAQS was not included as part of SIP revision. VerDate Sep<11>2014 18:44 Jul 29, 2016 Jkt 238001 requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference Jefferson County Regulation 1.02— Definitions (except for the definitions of ‘‘Acute noncancer effect,’’ ‘‘Cancer,’’ ‘‘Carcinogen,’’ and ‘‘Chronic noncancer effect’’) and Regulation 3.01—Ambient Air Quality Standards. EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the Region 4 office (see the ADDRESSES section of this preamble for more information). IV. Proposed Action EPA is proposing to approve the portions of the Commonwealth of Kentucky’s March 22, 2011, and May 3, 2012, SIP revisions identified in section II, above, because they are consistent with the CAA. V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: • Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 104–4); • does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 • is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and • does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). The SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.

II. Background On September 21, 2006, the EPA revised the primary 24-hour NAAQS for PM2.5 to 35 micrograms per cubic meter (mg/m3) (71 FR 61144, Oct. 17, 2006). On March 12, 2008, the EPA revised the levels of the primary and secondary 8hour ozone standards to 0.075 parts per million (ppm) (73 FR 16436, Mar. 27, 2008). On October 15, 2008, the EPA revised the level of the primary and secondary Pb NAAQS to 0.15 mg/m3 (73 FR 66964, Nov. 12, 2008). On January 22, 2010, the EPA promulgated a new 1hour primary NAAQS for NO2 at a level of 100 parts per billion (ppb) while retaining the annual standard of 53 ppb (75 FR 6474, Feb. 9, 2010). The secondary NO2 NAAQS remains unchanged at 53 ppb. On June 2, 2010, the EPA promulgated a revised primary 1-hour SO2 standard at 75 ppb (75 FR 35520, June 22, 2010). Finally, on December 14, 2012, the EPA promulgated a revised annual PM2.5 standard by lowering the level to 12.0 mg/m3 and retaining the 24-hour PM2.5 standard at a level of 35 mg/m3 (78 FR 3086, Jan. 15, 2013). Pursuant to section 110(a)(1) of the CAA, states are required to submit SIPs meeting the applicable requirements of PO 00000 Frm 00026 Fmt 4702 Sfmt 4702 50431 section 110(a)(2) within three years after promulgation of a new or revised NAAQS or within such shorter period as the EPA may prescribe. Section 110(a)(2) requires states to address structural SIP elements such as monitoring, basic program requirements, and legal authority that are designed to provide for implementation, maintenance, and enforcement of the NAAQS. The SIP submission required by these provisions is referred to as the ‘‘infrastructure’’ SIP. Section 110(a) imposes the obligation upon states to make a SIP submission to the EPA for a new or revised NAAQS, but the contents of individual state submissions may vary depending upon the facts and circumstances. CAA section 110(a)(2)(D)(i)(I) requires SIPs to include provisions prohibiting any source or other type of emissions activity in one state from emitting any air pollutant in amounts that will contribute significantly to nonattainment, or interfere with maintenance, of the NAAQS in another state (known as the ‘‘good neighbor’’ provision). The two provisions of this section are referred to as prong 1 (significant contribution to nonattainment) and prong 2 (interfere with maintenance). Section 110(a)(2)(D)(i)(II) requires SIPs to contain adequate provisions to prohibit emissions that will interfere with measures required to be included in the applicable implementation plan for any other state under part C to prevent significant deterioration of air quality (prong 3) or to protect visibility (prong 4). In this action, the EPA is addressing prong 4 with regard to the 2006 and 2012 PM2.5, 2008 ozone, 2008 Pb, 2010 SO2 and 2010 NO2 NAAQS. The EPA addressed prongs 1 and 2 for the 2008 ozone and 2008 Pb NAAQS in a proposed action published May 10, 2016 (81 FR 28807), and intends to finalize that action in conjunction with the actions in this proposed rule in one joint, final rulemaking. The EPA is addressing prong 3 for the applicable NAAQS in a separate action proposed April 26, 2016 (81 FR 24525), which can be found in regulations.gov under the docket EPA–R08–OAR–2013–0561. III. State Submissions The Utah Department of Environmental Quality (Department or UDEQ) submitted the following: A certification of Utah’s infrastructure SIP for the 2006 PM2.5 NAAQS on September 21, 2010; a certification of Utah’s infrastructure SIP for the 2008 Pb SIP on January 19, 2012; a certification of Utah’s infrastructure SIP for the 2008 E:\FR\FM\01AUP1.SGM 01AUP1 50432 Federal Register / Vol. 81, No. 147 / Monday, August 1, 2016 / Proposed Rules ozone NAAQS and 2010 NO2 NAAQS on January 31, 2013; a certification of Utah’s infrastructure SIP for the 2010 SO2 NAAQS on June 2, 2013; and a certification of Utah’s infrastructure SIP for the 2012 PM2.5 on December 22, 2015. Each of these infrastructure certifications addressed all of the required infrastructure elements under section 110(a)(2).1 As noted above, the EPA is only addressing the 110(a)(2)(D)(i)(II), prong 4 (visibility) element of each of these submissions here; all other infrastructure elements from these certifications are being addressed in separate actions. In Utah’s 2006 PM2.5 infrastructure certification, UDEQ pointed to SIP language verifying that no Utah sources of emissions interfere with implementation of reasonably attributable visibility impairment (RAVI) SIPs in other states, in accordance with EPA guidance.2 In Utah’s 2006 PM2.5, 2008 ozone, 2010 SO2, 2010 NO2 and 2012 PM2.5 NAAQS infrastructure certifications, the Department pointed to its Regional Haze SIP (Utah SIP Section XX) to certify that the State meets the visibility requirements of section 110(a)(2)(D)(i)(II). Utah specifically noted in each of these submittals (aside from the 2006 PM2.5 submittal) that the State had consulted with other states in the Western Regional Air Partnership (WRAP), and that reductions in emissions from Utah were included in the WRAP regional visibility modeling. As explained below, this information is relevant in determining whether Utah’s SIP will achieve the emission reductions that the WRAP states mutually agreed are necessary to avoid interstate visibility impacts in Class I areas.3 UDEQ addressed visibility for the 2008 Pb NAAQS by pointing to the short distance travelled by Pb emissions, and by noting that there was not a significant source of Pb in Utah within 100 miles of a Class I area. IV. Utah’s Regional Haze SIP As stated in the EPA’s September 13, 2013 Infrastructure SIP Guidance Memo sradovich on DSK3GMQ082PROD with PROPOSALS 1 For discussion of other infrastructure elements, see EPA’s ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and (2),’’ September 13, 2013. 2 See EPA’s ‘‘Guidance on SIP Elements Required Under Sections 110(a)(1) and (2) for the 2006 24Hour Fine Particle (PM2.5) National Ambient Air Quality Standards (NAAQS),’’ September 25, 2009, at 6. 3 See ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and (2),’’ September 13, 2013, at 34. VerDate Sep<11>2014 18:44 Jul 29, 2016 Jkt 238001 (‘‘2013 Guidance’’), ‘‘[o]ne way in which prong 4 may be satisfied for any relevant NAAQS is through an air agency’s confirmation in its infrastructure SIP submission that it has an approved regional haze SIP that fully meets the requirements of 40 CFR 51.308 or 51.309. 40 CFR 51.308 and 51.309 specifically require that a state participating in a regional planning process include all measures needed to achieve its apportionment of emission reduction obligations agreed upon through that process.’’ 4 On May 26, 2011, Utah submitted to the EPA a SIP revision to address the requirements of the regional haze program. The EPA partially approved and partially disapproved Utah’s SIP revision on December 14, 2012 (77 FR 74355). In that action, the EPA disapproved Utah’s NOX and PM10 Best Available Retrofit Technology (BART) determinations (77 FR 74357), and approved Utah’s BART alternative for SO2, which relied on the State’s participation in the backstop SO2 trading program.5 In response to the EPA’s December 14, 2012 partial disapproval, UDEQ submitted further SIP revisions on June 4, 2015, and October 20, 2015, to meet the regional haze requirements for NOX and PM10 BART. Instead of establishing BART controls for NOX, Utah’s SIP revisions contained an alternative to BART. The revisions also included BART controls for PM10. On July 5, 2016, the EPA finalized action on Utah’s June 4, 2015 Regional Haze SIP, approving the PM10 BART determinations for both the affected sources, the Hunter and Huntington power plants, and disapproving the State’s NOX BART alternative for these two facilities. The EPA also promulgated a final federal implementation plan (FIP) to address the deficiencies in Utah’s NOX BART determinations and the associated monitoring, recordkeeping and reporting requirements for both the Hunter and Huntington power plants (81 FR 43894, July 5, 2016). V. EPA’s Assessment The 2013 Guidance states that section 110(a)(2)(D)(i)(II)’s prong 4 requirements can be satisfied by approved SIP provisions that the EPA has found to adequately address a state’s contribution to visibility impairment in other states. 4 See ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and (2),’’ September 13, 2013, at 33. 5 EPA’s final approval of the ‘‘Western Backstop Sulfur Dioxide Trading Program’’ into the Utah SIP is codified at 40 CFR 52.2320(c)(71)(C) and (D). PO 00000 Frm 00027 Fmt 4702 Sfmt 4702 The EPA interprets prong 4 to be pollutant-specific, such that the infrastructure SIP submission need only address the potential for interference with protection of visibility caused by the pollutant (including precursors) to which the new or revised NAAQS applies.6 The 2013 Guidance lays out two ways in which a state’s infrastructure SIP submittal may satisfy prong 4. As explained above, one way is through a state’s confirmation in its infrastructure SIP submittal that it has an EPA approved regional haze SIP in place. In the absence of a fully approved regional haze SIP, a state can make a demonstration in its infrastructure SIP submittal that emissions within its jurisdiction do not interfere with other states’ plans to protect visibility. Such a submittal should point to measures in the state’s SIP that limit visibilityimpairing pollutants and ensure that the resulting reductions conform with any mutually agreed emission reductions under the relevant regional haze regional planning organization (RPO) process.7 UDEQ worked through its RPO, the WRAP, to develop strategies to address regional haze. To help states in establishing reasonable progress goals for improving visibility in Class I areas, the WRAP modeled future visibility conditions based on the mutually agreed emissions reductions from each state. The WRAP states then relied on this modeling in setting their respective reasonable progress goals. As a result, we consider emissions reductions from measures in Utah’s SIP that conform with the level of emission reductions the State agreed to include in the WRAP modeling to meet the visibility requirement of CAA section 110(a)(2)(D)(i)(II). With regard to the 2010 SO2 NAAQS, the EPA proposes to find that the State’s implementation of the Western Backstop Sulfur Dioxide Trading Program and the agreed upon SO2 reductions achieved through that program sufficient to meet the requirements of prong 4.8 Under 40 CFR 6 See ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and (2)’’ at 33. 7 See ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and (2)’’ at 34, and also 76 FR 22036 (April 20, 2011) containing EPA’s approval of the visibility requirement of 110(a)(2)(D)(i)(II) based on a demonstration by Colorado that did not rely on the Colorado Regional Haze SIP. 8 Specifically, the State is required to reach its ‘‘emissions milestone’’ for this program by keeping its SO2 emissions below 141,849 tons/SO2 in 2018 and each year thereafter. E:\FR\FM\01AUP1.SGM 01AUP1 sradovich on DSK3GMQ082PROD with PROPOSALS Federal Register / Vol. 81, No. 147 / Monday, August 1, 2016 / Proposed Rules 51.309, certain states, including Utah, can satisfy their SO2 BART requirements by adopting an alternative program consisting of SO2 emission milestones and a backstop trading program.9 Utah Administrative Rules (UAR) R307–250 and R307–150 implement the backstop trading program provisions and the EPA has approved the State’s rules, including the SO2 reduction milestones, as satisfying its regional haze SO2 obligations.10 Utah’s SIP thus contains measures requiring reductions of SO2 consistent with what the State agreed to achieve under the WRAP process in order to protect visibility. As a result, EPA is proposing to approve 110(a)(2)(D)(i)(II) prong 4 for the 2010 SO2 NAAQS. The EPA is also proposing to approve Utah’s prong 4 SIP submittal for the 2008 Pb NAAQS. The EPA agrees with UDEQ’s submission, which states that significant impacts from Pb emissions from stationary sources are expected to be limited to short distances from the source. The State also noted that it does not have any major sources of Pb located within 100 miles of a neighboring state’s Class I area. Further, when evaluating the extent to which Pb could impact visibility, the EPA has found Pb-related visibility impacts insignificant (e.g., less than 0.10 percent).11 The EPA proposes to approve prong 4 for the 2008 Pb NAAQS based on Utah’s conclusion that it does not have any significant sources of lead emissions near another state’s Class I area and that it, therefore, does not have emissions of Pb that would interfere with the requirements of section 110(a)(2)(D)(i)(II) with respect to visibility. The EPA is proposing to disapprove Utah’s prong 4 infrastructure SIP submittals for the 2006 PM2.5, 2008 ozone, 2010 NO2, and 2012 PM2.5 NAAQS. The EPA’s disapproval of Utah’s NOX BART determination in our July 5, 2016 final rulemaking included the specific disapproval of the NOX control measures the State submitted for the Hunter and Huntington facilities (81 FR 43894, 43902). As noted, Utah relied on its Regional Haze SIP (Utah SIP Section XX), and specifically its participation in the WRAP, as justification for the approvability of prong 4 for 2006 PM2.5, 2008 ozone, 2010 NO2 and 2012 PM2.5 NAAQS. Because the Department did not provide an alternative demonstration that its SIP contains 9 40 CFR 51.309. FR 74355 (Dec. 14, 2012). 11 EPA’s September 13, 2013 Infrastructure SIP Guidance, at 33. 10 77 VerDate Sep<11>2014 18:44 Jul 29, 2016 Jkt 238001 measures to limit NOX emissions in accordance with the emission reductions it agreed to under the WRAP,12 the EPA’s disapproval of Utah’s NOX BART alternative makes Utah’s justification insufficient for the NAAQS pollutants impacted by the control of NOX. Specifically, NOX is a precursor of PM2.5 and ozone, and is also a term which refers to both NO (nitrogen oxide) and NO2. The EPA is therefore proposing to disapprove prong 4 of Utah’s infrastructure certifications with regard to the 2006 PM2.5, 2008 ozone, 2010 NO2 and 2012 PM2.5 NAAQS. If the EPA disapproves an infrastructure SIP submission for prong 4, as we are proposing for the 2006 PM2.5, 2008 Ozone, 2010 NO2 and 2012 PM2.5 NAAQS, a FIP obligation will be created. However, since the EPA recently promulgated a FIP for Utah that corrects all regional haze SIP deficiencies (81 FR 43894), there will be no additional practical consequences from the disapproval for UDEQ, the sources within its jurisdiction, or the EPA.13 The EPA will not be required to take further action with respect to these prong 4 disapprovals, if finalized, because the FIP already in place would satisfy the requirements with respect to prong 4.14 Additionally, since the infrastructure SIP submission is not required in response to a SIP call under CAA section 110(k)(5), mandatory sanctions under CAA section 179 would not apply because the deficiencies are not with respect to a submission that is required under CAA title I part D.15 VI. Proposed Action The EPA is proposing to approve portions of Utah’s infrastructure certifications which address the interstate transport requirements of CAA section 110(a)(2)(D)(i)(II), and to disapprove portions of other certifications addressing this CAA requirement. The EPA is proposing to approve 110(a)(2)(D)(i)(II) prong 4 for the 2008 Pb and 2010 SO2 NAAQS. The EPA is also proposing to disapprove 110(a)(2)(D)(i)(II) prong 4 for the 2006 PM2.5, 2008 ozone, 2010 NO2 and 2012 PM2.5 NAAQS. The EPA is soliciting public comments on this proposed action and will consider public comments received during the comment period. 12 With the exception of the 2006 PM 2.5 NAAQS, which referenced the State’s lack of interference with RAVI. 13 EPA’s September 13, 2013 Infrastructure SIP Guidance, at 34. 14 Id. at 35. 15 Id.

Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state actions, provided that they meet the criteria of the Clean Air Act. Accordingly, this proposed action merely proposes approval of some state law as meeting federal requirements and proposes disapproval of other state law because it does not meet federal requirements; this proposed action does not propose additional requirements beyond those imposed by state law. For that reason, this proposed action: • Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 104–4); • Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and • Does not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, the SIP does not apply on any Indian reservation land or in any other area where the EPA or an Indian E:\FR\FM\01AUP1.SGM 01AUP1 50434 Federal Register / Vol. 81, No. 147 / Monday, August 1, 2016 / Proposed Rules tribe has demonstrated that a tribe has jurisdiction.

Background The Environmental Protection Agency (EPA) will be proposing a rule to establish public notification requirements for combined sewer overflows (CSOs) to the Great Lakes, as required by Section 425 of the Consolidated Appropriations Act of 2016 (Pub. L. 114–113) (hereafter, referred to as ‘‘Section 425’’). Section 425 requires EPA to work with the Great Lakes states to create these public notice requirements, and EPA is also seeking public input in the development of these requirements. Combined Sewer Overflows From Municipal Wastewater Collection Systems Municipal wastewater collection systems collect domestic sewage and other wastewater from homes and other buildings and convey it to wastewater treatment plants for proper treatment and disposal. The collection and treatment of municipal sewage and wastewater is vital to the public health in our cities and towns. In the United States, municipalities historically have used two major types of sewer systems. Many municipalities collect domestic sewage in a sanitary sewer system and convey the sewage to a publicly owned treatment works (POTW) for treatment. These municipalities also have separate sewer systems to collect surface E:\FR\FM\01AUP1.SGM 01AUP1

II. Background

    On September 21, 2006, the EPA revised the primary 24-hour NAAQS 
for PM2.5 to 35 micrograms per cubic meter ([mu]g/m\3\) (71 
FR 61144, Oct. 17, 2006). On March 12, 2008, the EPA revised the levels 
of the primary and secondary 8-hour ozone standards to 0.075 parts per 
million (ppm) (73 FR 16436, Mar. 27, 2008). On October 15, 2008, the 
EPA revised the level of the primary and secondary Pb NAAQS to 0.15 
[mu]g/m\3\ (73 FR 66964, Nov. 12, 2008). On January 22, 2010, the EPA 
promulgated a new 1-hour primary NAAQS for NO2 at a level of 
100 parts per billion (ppb) while retaining the annual standard of 53 
ppb (75 FR 6474, Feb. 9, 2010). The secondary NO2 NAAQS 
remains unchanged at 53 ppb. On June 2, 2010, the EPA promulgated a 
revised primary 1-hour SO2 standard at 75 ppb (75 FR 35520, 
June 22, 2010). Finally, on December 14, 2012, the EPA promulgated a 
revised annual PM2.5 standard by lowering the level to 12.0 
[mu]g/m\3\ and retaining the 24-hour PM2.5 standard at a 
level of 35 [mu]g/m\3\ (78 FR 3086, Jan. 15, 2013).
    Pursuant to section 110(a)(1) of the CAA, states are required to 
submit SIPs meeting the applicable requirements of section 110(a)(2) 
within three years after promulgation of a new or revised NAAQS or 
within such shorter period as the EPA may prescribe. Section 110(a)(2) 
requires states to address structural SIP elements such as monitoring, 
basic program requirements, and legal authority that are designed to 
provide for implementation, maintenance, and enforcement of the NAAQS. 
The SIP submission required by these provisions is referred to as the 
``infrastructure'' SIP. Section 110(a) imposes the obligation upon 
states to make a SIP submission to the EPA for a new or revised NAAQS, 
but the contents of individual state submissions may vary depending 
upon the facts and circumstances.
    CAA section 110(a)(2)(D)(i)(I) requires SIPs to include provisions 
prohibiting any source or other type of emissions activity in one state 
from emitting any air pollutant in amounts that will contribute 
significantly to nonattainment, or interfere with maintenance, of the 
NAAQS in another state (known as the ``good neighbor'' provision). The 
two provisions of this section are referred to as prong 1 (significant 
contribution to nonattainment) and prong 2 (interfere with 
maintenance). Section 110(a)(2)(D)(i)(II) requires SIPs to contain 
adequate provisions to prohibit emissions that will interfere with 
measures required to be included in the applicable implementation plan 
for any other state under part C to prevent significant deterioration 
of air quality (prong 3) or to protect visibility (prong 4).
    In this action, the EPA is addressing prong 4 with regard to the 
2006 and 2012 PM2.5, 2008 ozone, 2008 Pb, 2010 
SO2 and 2010 NO2 NAAQS. The EPA addressed prongs 
1 and 2 for the 2008 ozone and 2008 Pb NAAQS in a proposed action 
published May 10, 2016 (81 FR 28807), and intends to finalize that 
action in conjunction with the actions in this proposed rule in one 
joint, final rulemaking. The EPA is addressing prong 3 for the 
applicable NAAQS in a separate action proposed April 26, 2016 (81 FR 
24525), which can be found in regulations.gov under the docket EPA-R08-
OAR-2013-0561.

III. State Submissions

    The Utah Department of Environmental Quality (Department or UDEQ) 
submitted the following: A certification of Utah's infrastructure SIP 
for the 2006 PM2.5 NAAQS on September 21, 2010; a 
certification of Utah's infrastructure SIP for the 2008 Pb SIP on 
January 19, 2012; a certification of Utah's infrastructure SIP for the 
2008

[[Page 50432]]

ozone NAAQS and 2010 NO2 NAAQS on January 31, 2013; a 
certification of Utah's infrastructure SIP for the 2010 SO2 
NAAQS on June 2, 2013; and a certification of Utah's infrastructure SIP 
for the 2012 PM2.5 on December 22, 2015.
    Each of these infrastructure certifications addressed all of the 
required infrastructure elements under section 110(a)(2).\1\ As noted 
above, the EPA is only addressing the 110(a)(2)(D)(i)(II), prong 4 
(visibility) element of each of these submissions here; all other 
infrastructure elements from these certifications are being addressed 
in separate actions.
---------------------------------------------------------------------------

    \1\ For discussion of other infrastructure elements, see EPA's 
``Guidance on Infrastructure State Implementation Plan (SIP) 
Elements under Clean Air Act Sections 110(a)(1) and (2),'' September 
13, 2013.
---------------------------------------------------------------------------

    In Utah's 2006 PM2.5 infrastructure certification, UDEQ 
pointed to SIP language verifying that no Utah sources of emissions 
interfere with implementation of reasonably attributable visibility 
impairment (RAVI) SIPs in other states, in accordance with EPA 
guidance.\2\
---------------------------------------------------------------------------

    \2\ See EPA's ``Guidance on SIP Elements Required Under Sections 
110(a)(1) and (2) for the 2006 24-Hour Fine Particle 
(PM2.5) National Ambient Air Quality Standards (NAAQS),'' 
September 25, 2009, at 6.
---------------------------------------------------------------------------

    In Utah's 2006 PM2.5, 2008 ozone, 2010 SO2, 
2010 NO2 and 2012 PM2.5 NAAQS infrastructure 
certifications, the Department pointed to its Regional Haze SIP (Utah 
SIP Section XX) to certify that the State meets the visibility 
requirements of section 110(a)(2)(D)(i)(II). Utah specifically noted in 
each of these submittals (aside from the 2006 PM2.5 
submittal) that the State had consulted with other states in the 
Western Regional Air Partnership (WRAP), and that reductions in 
emissions from Utah were included in the WRAP regional visibility 
modeling. As explained below, this information is relevant in 
determining whether Utah's SIP will achieve the emission reductions 
that the WRAP states mutually agreed are necessary to avoid interstate 
visibility impacts in Class I areas.\3\
---------------------------------------------------------------------------

    \3\ See ``Guidance on Infrastructure State Implementation Plan 
(SIP) Elements under Clean Air Act Sections 110(a)(1) and (2),'' 
September 13, 2013, at 34.
---------------------------------------------------------------------------

    UDEQ addressed visibility for the 2008 Pb NAAQS by pointing to the 
short distance travelled by Pb emissions, and by noting that there was 
not a significant source of Pb in Utah within 100 miles of a Class I 
area.

IV. Utah's Regional Haze SIP

    As stated in the EPA's September 13, 2013 Infrastructure SIP 
Guidance Memo (``2013 Guidance''), ``[o]ne way in which prong 4 may be 
satisfied for any relevant NAAQS is through an air agency's 
confirmation in its infrastructure SIP submission that it has an 
approved regional haze SIP that fully meets the requirements of 40 CFR 
51.308 or 51.309. 40 CFR 51.308 and 51.309 specifically require that a 
state participating in a regional planning process include all measures 
needed to achieve its apportionment of emission reduction obligations 
agreed upon through that process.'' \4\
---------------------------------------------------------------------------

    \4\ See ``Guidance on Infrastructure State Implementation Plan 
(SIP) Elements under Clean Air Act Sections 110(a)(1) and (2),'' 
September 13, 2013, at 33.
---------------------------------------------------------------------------

    On May 26, 2011, Utah submitted to the EPA a SIP revision to 
address the requirements of the regional haze program. The EPA 
partially approved and partially disapproved Utah's SIP revision on 
December 14, 2012 (77 FR 74355). In that action, the EPA disapproved 
Utah's NOX and PM10 Best Available Retrofit 
Technology (BART) determinations (77 FR 74357), and approved Utah's 
BART alternative for SO2, which relied on the State's 
participation in the backstop SO2 trading program.\5\
---------------------------------------------------------------------------

    \5\ EPA's final approval of the ``Western Backstop Sulfur 
Dioxide Trading Program'' into the Utah SIP is codified at 40 CFR 
52.2320(c)(71)(C) and (D).
---------------------------------------------------------------------------

    In response to the EPA's December 14, 2012 partial disapproval, 
UDEQ submitted further SIP revisions on June 4, 2015, and October 20, 
2015, to meet the regional haze requirements for NOX and 
PM10 BART. Instead of establishing BART controls for 
NOX, Utah's SIP revisions contained an alternative to BART. 
The revisions also included BART controls for PM10.
    On July 5, 2016, the EPA finalized action on Utah's June 4, 2015 
Regional Haze SIP, approving the PM10 BART determinations 
for both the affected sources, the Hunter and Huntington power plants, 
and disapproving the State's NOX BART alternative for these 
two facilities. The EPA also promulgated a final federal implementation 
plan (FIP) to address the deficiencies in Utah's NOX BART 
determinations and the associated monitoring, recordkeeping and 
reporting requirements for both the Hunter and Huntington power plants 
(81 FR 43894, July 5, 2016).

V. EPA's Assessment

    The 2013 Guidance states that section 110(a)(2)(D)(i)(II)'s prong 4 
requirements can be satisfied by approved SIP provisions that the EPA 
has found to adequately address a state's contribution to visibility 
impairment in other states. The EPA interprets prong 4 to be pollutant-
specific, such that the infrastructure SIP submission need only address 
the potential for interference with protection of visibility caused by 
the pollutant (including precursors) to which the new or revised NAAQS 
applies.\6\
---------------------------------------------------------------------------

    \6\ See ``Guidance on Infrastructure State Implementation Plan 
(SIP) Elements under Clean Air Act Sections 110(a)(1) and (2)'' at 
33.
---------------------------------------------------------------------------

    The 2013 Guidance lays out two ways in which a state's 
infrastructure SIP submittal may satisfy prong 4. As explained above, 
one way is through a state's confirmation in its infrastructure SIP 
submittal that it has an EPA approved regional haze SIP in place. In 
the absence of a fully approved regional haze SIP, a state can make a 
demonstration in its infrastructure SIP submittal that emissions within 
its jurisdiction do not interfere with other states' plans to protect 
visibility. Such a submittal should point to measures in the state's 
SIP that limit visibility-impairing pollutants and ensure that the 
resulting reductions conform with any mutually agreed emission 
reductions under the relevant regional haze regional planning 
organization (RPO) process.\7\
---------------------------------------------------------------------------

    \7\ See ``Guidance on Infrastructure State Implementation Plan 
(SIP) Elements under Clean Air Act Sections 110(a)(1) and (2)'' at 
34, and also 76 FR 22036 (April 20, 2011) containing EPA's approval 
of the visibility requirement of 110(a)(2)(D)(i)(II) based on a 
demonstration by Colorado that did not rely on the Colorado Regional 
Haze SIP.
---------------------------------------------------------------------------

    UDEQ worked through its RPO, the WRAP, to develop strategies to 
address regional haze. To help states in establishing reasonable 
progress goals for improving visibility in Class I areas, the WRAP 
modeled future visibility conditions based on the mutually agreed 
emissions reductions from each state. The WRAP states then relied on 
this modeling in setting their respective reasonable progress goals. As 
a result, we consider emissions reductions from measures in Utah's SIP 
that conform with the level of emission reductions the State agreed to 
include in the WRAP modeling to meet the visibility requirement of CAA 
section 110(a)(2)(D)(i)(II).
    With regard to the 2010 SO2 NAAQS, the EPA proposes to 
find that the State's implementation of the Western Backstop Sulfur 
Dioxide Trading Program and the agreed upon SO2 reductions 
achieved through that program sufficient to meet the requirements of 
prong 4.\8\ Under 40 CFR

[[Page 50433]]

51.309, certain states, including Utah, can satisfy their 
SO2 BART requirements by adopting an alternative program 
consisting of SO2 emission milestones and a backstop trading 
program.\9\ Utah Administrative Rules (UAR) R307-250 and R307-150 
implement the backstop trading program provisions and the EPA has 
approved the State's rules, including the SO2 reduction 
milestones, as satisfying its regional haze SO2 
obligations.\10\ Utah's SIP thus contains measures requiring reductions 
of SO2 consistent with what the State agreed to achieve 
under the WRAP process in order to protect visibility. As a result, EPA 
is proposing to approve 110(a)(2)(D)(i)(II) prong 4 for the 2010 
SO2 NAAQS.
---------------------------------------------------------------------------

    \8\ Specifically, the State is required to reach its ``emissions 
milestone'' for this program by keeping its SO2 emissions 
below 141,849 tons/SO2 in 2018 and each year thereafter.
    \9\ 40 CFR 51.309.
    \10\ 77 FR 74355 (Dec. 14, 2012).
---------------------------------------------------------------------------

    The EPA is also proposing to approve Utah's prong 4 SIP submittal 
for the 2008 Pb NAAQS. The EPA agrees with UDEQ's submission, which 
states that significant impacts from Pb emissions from stationary 
sources are expected to be limited to short distances from the source. 
The State also noted that it does not have any major sources of Pb 
located within 100 miles of a neighboring state's Class I area. 
Further, when evaluating the extent to which Pb could impact 
visibility, the EPA has found Pb-related visibility impacts 
insignificant (e.g., less than 0.10 percent).\11\ The EPA proposes to 
approve prong 4 for the 2008 Pb NAAQS based on Utah's conclusion that 
it does not have any significant sources of lead emissions near another 
state's Class I area and that it, therefore, does not have emissions of 
Pb that would interfere with the requirements of section 
110(a)(2)(D)(i)(II) with respect to visibility.
---------------------------------------------------------------------------

    \11\ EPA's September 13, 2013 Infrastructure SIP Guidance, at 
33.
---------------------------------------------------------------------------

    The EPA is proposing to disapprove Utah's prong 4 infrastructure 
SIP submittals for the 2006 PM2.5, 2008 ozone, 2010 
NO2, and 2012 PM2.5 NAAQS. The EPA's disapproval 
of Utah's NOX BART determination in our July 5, 2016 final 
rulemaking included the specific disapproval of the NOX 
control measures the State submitted for the Hunter and Huntington 
facilities (81 FR 43894, 43902).
    As noted, Utah relied on its Regional Haze SIP (Utah SIP Section 
XX), and specifically its participation in the WRAP, as justification 
for the approvability of prong 4 for 2006 PM2.5, 2008 ozone, 
2010 NO2 and 2012 PM2.5 NAAQS. Because the 
Department did not provide an alternative demonstration that its SIP 
contains measures to limit NOX emissions in accordance with 
the emission reductions it agreed to under the WRAP,\12\ the EPA's 
disapproval of Utah's NOX BART alternative makes Utah's 
justification insufficient for the NAAQS pollutants impacted by the 
control of NOX. Specifically, NOX is a precursor 
of PM2.5 and ozone, and is also a term which refers to both 
NO (nitrogen oxide) and NO2. The EPA is therefore proposing 
to disapprove prong 4 of Utah's infrastructure certifications with 
regard to the 2006 PM2.5, 2008 ozone, 2010 NO2 
and 2012 PM2.5 NAAQS.
---------------------------------------------------------------------------

    \12\ With the exception of the 2006 PM2.5 NAAQS, 
which referenced the State's lack of interference with RAVI.
---------------------------------------------------------------------------

    If the EPA disapproves an infrastructure SIP submission for prong 
4, as we are proposing for the 2006 PM2.5, 2008 Ozone, 2010 
NO2 and 2012 PM2.5 NAAQS, a FIP obligation will 
be created. However, since the EPA recently promulgated a FIP for Utah 
that corrects all regional haze SIP deficiencies (81 FR 43894), there 
will be no additional practical consequences from the disapproval for 
UDEQ, the sources within its jurisdiction, or the EPA.\13\ The EPA will 
not be required to take further action with respect to these prong 4 
disapprovals, if finalized, because the FIP already in place would 
satisfy the requirements with respect to prong 4.\14\ Additionally, 
since the infrastructure SIP submission is not required in response to 
a SIP call under CAA section 110(k)(5), mandatory sanctions under CAA 
section 179 would not apply because the deficiencies are not with 
respect to a submission that is required under CAA title I part D.\15\

VI. Proposed Action

    The EPA is proposing to approve portions of Utah's infrastructure 
certifications which address the interstate transport requirements of 
CAA section 110(a)(2)(D)(i)(II), and to disapprove portions of other 
certifications addressing this CAA requirement. The EPA is proposing to 
approve 110(a)(2)(D)(i)(II) prong 4 for the 2008 Pb and 2010 
SO2 NAAQS. The EPA is also proposing to disapprove 
110(a)(2)(D)(i)(II) prong 4 for the 2006 PM2.5, 2008 ozone, 
2010 NO2 and 2012 PM2.5 NAAQS. The EPA is 
soliciting public comments on this proposed action and will consider 
public comments received during the comment period.

VII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to approve state actions, 
provided that they meet the criteria of the Clean Air Act. Accordingly, 
this proposed action merely proposes approval of some state law as 
meeting federal requirements and proposes disapproval of other state 
law because it does not meet federal requirements; this proposed action 
does not propose additional requirements beyond those imposed by state 
law. For that reason, this proposed action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4);
     Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     Does not provide the EPA with the discretionary authority 
to address, as appropriate, disproportionate human health or 
environmental effects, using practicable and legally permissible 
methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, the SIP does not apply on any Indian reservation land 
or in any other area where the EPA or an Indian

[[Page 50434]]

tribe has demonstrated that a tribe has jurisdiction. In those areas of 
Indian country, the proposed rule does not have tribal implications and 
will not impose substantial direct costs on tribal governments or 
preempt tribal law as specified by Executive Order 13175 (65 FR 67249, 
November 9, 2000).
