ACTION: Proposed rule. AGENCY: EPA is proposing to make two separate and independent determinations regarding the LibertyClairton, Pennsylvania 1997 annual fine particulate (PM2.5) nonattainment area (the Liberty-Clairton Area). First, EPA is proposing to determine that the LibertyClairton Area attained the 1997 PM2.5 annual national ambient air quality standards (NAAQS) by the applicable attainment date, December 31, 2011. This proposed determination is based on quality assured and certified ambient air quality date for the 2009–2011 monitoring period. Second, EPA is proposing that the Liberty-Clairton Area has continued to attain the 1997 annual PM2.5 NAAQS, based on quality-assured and certified ambient air quality data for the 2010–2012 monitoring period. If EPA finalizes this latter ‘‘clean data determination,’’ the requirement for the Liberty-Clairton Area to submit an attainment demonstration, reasonably available control measures (RACM), reasonable further progress (RFP), and contingency measures related to attainment of the 1997 annual PM2.5 NAAQS would be suspended for so long as the area continues to attain the 1997 annual PM2.5 NAAQS. These determinations do not constitute a redesignation to attainment. The Liberty-Clairton Area will remain designated nonattainment for the 1997 annual PM2.5 NAAQS until such time as EPA determines that the LibertyClairton Area meets the Clean Air Act (CAA) requirements for redesignation to attainment, including an approved maintenance plan. These proposed actions are being taken under the CAA. DATES: Written comments must be received on or before August 22, 2013.

Summary of Proposed Actions EPA is proposing two separate and independent determinations regarding the Liberty-Clairton Area. First, pursuant to section 188(b)(2) of the CAA, EPA is proposing to make a determination that the Liberty-Clairton Area attained the 1997 annual PM2.5 NAAQS by the applicable attainment date, December 31, 2011. This proposed determination is based upon qualityassured and certified ambient air monitoring data for the 2009–2011 monitoring period that shows the area has monitored attainment of the 1997 PM2.5 annual NAAQS as of its attainment date. EPA is also proposing to make a determination that the Liberty-Clairton Area continues to attain the 1997 annual PM2.5 NAAQS. This proposed ‘‘clean data’’ determination is based upon quality assured and certified ambient air monitoring data that show the area has monitored attainment of the 1997 PM2.5 NAAQS for the 2010–2012 monitoring period. If EPA finalizes this determination, the requirement for the Liberty-Clairton Area to submit an attainment demonstration, RACM, RFP, and contingency measures related to attainment of the 1997 annual PM2.5 NAAQS shall be suspended for so long as the area continues to attain that NAAQS.1 II. Background A. The PM2.5 NAAQS On July 18, 1997 (62 FR 38652), EPA established a health-based PM2.5 NAAQS at 15.0 micrograms per cubic meter (mg/m3) based on a 3-year average of annual mean PM2.5 concentrations (‘‘the 1997 annual PM2.5 NAAQS’’ or ‘‘the 1997 annual standard’’). At that time, EPA also established a 24-hour standard of 65 mg/m3 (the ‘‘1997 24-hour standard’’). See 40 CFR 50.7. On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual PM2.5 NAAQS at 15 mg/m3 based on a 3-year average 1 Even if these requirements are suspended, EPA is not precluded from acting upon these elements at any time if submitted to EPA for review and approval. On June 17, 2011, the Commonwealth of Pennsylvania submitted a SIP revision for the Liberty-Clairton Area to EPA for review and approval. On November 7, 2011 (76 FR 68699), EPA proposed approval, with one condition, of Pennsylvania’s SIP revision for the Liberty-Clairton Area. E:\FR\FM\23JYP1.SGM 23JYP1 44071 Federal Register / Vol. 78, No. 141 / Tuesday, July 23, 2013 / Proposed Rules of annual mean PM2.5 concentrations, and promulgated a 24-hour standard of 35 mg/m3 based on a 3-year average of the 98th percentile of 24-hour concentrations (the ‘‘2006 24-hour standard’’). In response to legal challenges of the 2006 annual standard, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit or the Court) remanded this standard to EPA for further consideration. See, American Farm Bureau Federation and National Pork Producers Council, et al. v. EPA, 559 F.3d 512 (D.C. Circuit 2009). However, given that the 1997 and 2006 annual PM2.5 standards are essentially identical, attainment of the 1997 annual standard would also indicate attainment of the remanded 2006 annual standard. On December 14, 2012 (78 FR 3086), EPA lowered the primary annual PM2.5 NAAQS from 15 to 12.0 mg/m3. EPA retained the 2006 24-hour PM2.5 NAAQS, and the 1997 secondary annual PM2.5 NAAQS. EPA also retained the existing standards for coarse particle pollution (PM10). This rulemaking action proposes determinations solely for the 1997 annual PM2.5 standard. It does not address the 1997 or 2006 24hour PM2.5 standards or the 2012 PM2.5 annual NAAQS. B. The Liberty-Clairton Area On January 5, 2005 (70 FR 944), EPA published its air quality designations for the 1997 PM2.5 NAAQS based upon air quality monitoring data for calendar years 2001–2003. These designations became effective on April 5, 2005. The Liberty-Clairton Area is comprised of the boroughs of Lincoln, Glassport, Liberty, and Port Vue and the City of Clairton, all in Allegheny County, Pennsylvania. See 40 CFR 81.339. The Liberty-Clairton Area is surrounded by, but separate and distinct from the Pittsburgh-Beaver Valley PM2.5 nonattainment area. On November 13, 2009 (74 FR 58688), EPA published the area designations for the 2006 24-hour standard. That action, effective on December 14, 2009, designated the same Liberty-Clairton Area as nonattainment for the 2006 24hour standard and clarified that the Liberty-Clairton Area is designated as unclassifiable/attainment for the 1997 24-hour PM2.5 standard. III. EPA’s Analysis of the Relevant Air Quality Data The Commonwealth of Pennsylvania submitted quality assured air quality monitoring data into the EPA Air Quality System (AQS) database for the 2009–2011 and 2010–2012 monitoring periods. Pennsylvania then certified that data. EPA’s evaluation of this data shows that the Liberty-Clairton Area has attained the 1997 annual PM2.5 NAAQS by its 2011 attainment date, and that it continues to attain the 1997 annual PM2.5 NAAQS. Additional information on air quality data for the LibertyClairton Area can be found in the technical support document (TSD) prepared for this action. The criteria for determining if an area is attaining the 1997 annual PM2.5 NAAQS are set out in 40 CFR 50.13 and appendix N. The 1997 annual PM2.5 NAAQS is met when the annual design value is less than or equal to 15.0 mg/ m3. Three years of valid annual means are required to produce a valid annual standard design value. A year meets data completeness requirements when at least 75 percent of the scheduled sampling days for each quarter have valid data. The use of less than complete data is subject to the approval of EPA, which may consider factors such as monitoring site closures/moves, monitoring diligence, and nearby concentrations in determining whether to use such data. There are two PM2.5 monitors in the Liberty-Clairton Area—one in Liberty Borough and one in the City of Clairton. Both monitors had complete data for all quarters in the years 2009 through 2012, except for one calendar quarter in 2011 when the Clairton monitor had less than complete data capture due to unreliable data results via laboratory analysis. For this monitor, EPA performed a statistical analysis of the data, in which a linear regression relationship is established between the site with incomplete data and a nearby site which has more complete data in the period in which the incomplete site is missing data. The linear regression relationship is based on time periods in which both monitors were operating. The linear regression equation developed from the relationship between the monitors is used to fill in missing data for the incomplete monitor, so that the normal data completeness requirement of 75 percent of data in each quarter of the three years is met. After the missing data for the site is filled in, the results are verified through an additional statistical test. The results of EPA’s statistical analysis indicated that while the Liberty monitor had less than complete data, the data is sufficient to demonstrate that the NAAQS has been met. Details of this analysis are set out in the TSD prepared for this action. This proposed determination of attainment for the Liberty-Clairton Area is based on EPA’s evaluation of qualitycontrolled, quality assured, certified annual PM2.5 air quality data for the 2009–2011 and 2010–2012 monitoring periods. The monitoring data and calculated design values for LibertyClairton Area are summarized in Table 1 for the 2009–2011 monitoring period, and in Table 2 for the 2010–2012 monitoring period.

Consistent with the requirements contained in 40 CFR part 50, EPA has reviewed the PM2.5 ambient air monitoring data for the monitoring periods 2009–2011 and 2010–2012 for the Liberty-Clairton Area, as recorded in the AQS database. On the basis of that review, EPA proposes to determine that the Liberty-Clairton Area (1) attained the 1997 annual PM2.5 NAAQS by its attainment date, based on data for the 2009–2011 monitoring period, and (2) continued to attain during the 2010– 2012 monitoring period. ehiers on DSK2VPTVN1PROD with PROPOSALS-1 IV. Effect of Proposed Determinations of Attainment for 1997 PM2.5 NAAQS Under Subpart 4 of Part D of Title I of the CAA (Subpart 4) This section and section V of EPA’s proposal address the effects of a final clean data determination and a final determination of attainment by the attainment date for the Liberty-Clairton Area. For the 1997 annual PM2.5 standard, 40 CFR 51.004 of EPA’s Implementation Rule for the 1997 annual PM2.5 standard embodies EPA’s ‘‘Clean Data Policy’’ interpretation under subpart 1 of Part D of Title I of the CAA (subpart 1). The provisions of 40 CFR 51.004 set forth the effects of a determination of attainment for the 1997 PM2.5 standard. (72 FR 20585, 20665, April 25, 2007). On January 4, 2013, in Natural Resources Defense Council v. EPA, the DC Circuit remanded to EPA the ‘‘Final Clean Air Fine Particle Implementation Rule’’ (72 FR 20586, April 25, 2007) and the ‘‘Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM2.5)’’ final rule (73 FR 28321, May 16, 2008) (collectively, ‘‘1997 PM2.5 Implementation Rule’’ or ‘‘Implementation Rule’’). 706 F.3d 428 (D.C. Cir. 2013). The Court found that EPA erred in implementing the 1997 PM2.5 NAAQS pursuant solely to the general implementation provisions of subpart 1, rather than the particulatematter-specific provisions of subpart 4. The Court remanded EPA’s VerDate Mar<15>2010 17:43 Jul 22, 2013 Jkt 229001 Implementation Rule for further proceedings consistent with the Court’s decision. In light of the Court’s decision and its remand of the Implementation Rule, EPA in this proposed rulemaking action addresses the effect of a final determination of attainment for the Liberty-Clairton Area, as if that area were considered a moderate nonattainment area under subpart 4.2 As set forth in more detail below, under EPA’s Clean Data Policy interpretation, a determination that the area has attained the standard suspends the state’s obligation to submit attainmentrelated planning requirements of 4 (and the applicable provisions of subpart 1) for so long as the area continues to attain the standard. These include requirements to submit an attainment demonstration, RFP, RACM, and contingency measures, because the purpose of these provisions is to help reach attainment, a goal which has already been achieved. A. Background on Clean Data Policy Over the past two decades, EPA has consistently applied its ‘‘Clean Data Policy’’ interpretation to attainmentrelated provisions of subparts 1, 2 and 4. The Clean Data Policy is the subject of several EPA memoranda and regulations. In addition, numerous individual rulemakings published in the Federal Register have applied the 2 For the purposes of evaluating the effects of this proposed determination of attainment under subpart 4, EPA is considering the Liberty-Clairton Area to be a ‘‘moderate’’ PM2.5 nonattainment area. Under section 188 of the CAA, all areas designated nonattainment areas under subpart 4 would initially be classified by operation of law as ‘‘moderate’’ nonattainment areas, and would remain moderate nonattainment areas unless and until EPA reclassifies the area as a ‘‘serious’’ nonattainment area. Accordingly, EPA believes that it is appropriate to limit the evaluation of the potential impact of subpart 4 requirements to those that would be applicable to moderate nonattainment areas. Sections 189(a) and (c) of subpart 4 apply to moderate nonattainment areas and include an attainment demonstration (section 189(a)(1)(B)); (3) provisions for RACM (section 189(a)(1)(C)); and quantitative milestones demonstrating RFP toward attainment by the applicable attainment date (section 189(c)). In addition, EPA also evaluates the applicable requirements of subpart 1. PO 00000 Frm 00039 Fmt 4702 Sfmt 4702 interpretation to a spectrum of NAAQS, including the 1-hour and 1997 ozone, PM10, PM2.5, carbon monoxide (CO) and lead (Pb) standards. The D.C. Circuit has upheld the Clean Data Policy interpretation as embodied in EPA’s 1997 8-Hour Ozone Implementation Rule, 40 CFR 51.918.3 NRDC v. EPA, 571 F. 3d 1245 (D.C. Cir. 2009). Other U.S. Circuit Courts of Appeals that have considered and reviewed EPA’s Clean Data Policy interpretation have upheld it and the rulemakings applying EPA’s interpretation. Sierra Club v. EPA, 99 F.3d 1551 (10th Cir. 1996); Sierra Club v. EPA, 375 F. 3d 537 (7th Cir. 2004); Our Children’s Earth Foundation v. EPA, N. 04–73032 (9th Cir. June 28, 2005) (memorandum opinion), Latino Issues Forum, v. EPA, Nos. 06–75831 and 08–71238 (9th Cir.), Memorandum Opinion, March 2, 2009. As noted above, EPA incorporated its Clean Data Policy interpretation in both its 8-Hour Ozone Implementation Rule and in its PM2.5 Implementation Rule in 40 CFR 51.1004(c). (72 FR 20585, 20665, April 25, 2007). While the D.C. Circuit, in its January 4, 2013 decision, remanded the 1997 PM2.5 Implementation Rule, the Court did not address the merits of that regulation, nor cast doubt on EPA’s existing interpretation of the statutory provisions. However, in light of the Court’s decision, EPA’s Clean Data Policy interpretation under subpart 4 is set forth here, for the purpose of identifying the effects of a determination of attainment for the 1997 annual PM2.5 standard for the Liberty-Clairton Area. EPA has previously articulated its Clean Data interpretation under subpart 4 in implementing the PM10 standard. See, e.g., (75 FR 27944, May 19, 2010) (determination of attainment of the PM10 standard in Coso Junction, California); (75 FR 6571, February 10, 2010), (71 FR 6352, February 8, 2006) 3 ‘‘EPA’s Final Rule to implement the 8-Hour Ozone National Ambient Air Quality StandardPhase 2 (Phase 2 Final Rule)’’ (70 FR 71612, 71645– 46, November 29, 2005). E:\FR\FM\23JYP1.SGM 23JYP1 Federal Register / Vol. 78, No. 141 / Tuesday, July 23, 2013 / Proposed Rules ehiers on DSK2VPTVN1PROD with PROPOSALS-1 (Ajo, Arizona Area); (71 FR 13021, March 14, 2006) (Yuma, Arizona Area); (71 FR 40023, July 14, 2006) (Weirton, West Virginia Area); (71 FR 44920, August 8, 2006) (Rillito, Arizona Area); (71 FR 63642, October 30, 2006) (San Joaquin Valley, California Area); (72 FR 14422, March 28, 2007) (Miami, Arizona Area); (75 FR 27944, May 19, 2010) (Coso Junction, California Area). Thus EPA has established that, under subpart 4, an attainment determination suspends the obligations to submit an attainment demonstration, RACM, RFP contingency measures, and other measures related to attainment. B. Application of the Clean Data Policy to Attainment-Related Provisions of Subpart 4 In EPA’s proposed and final rulemaking actions determining that the San Joaquin Valley nonattainment area attained the PM10 standard, EPA set forth at length its rationale for applying the Clean Data Policy to PM10 under subpart 4. The Ninth Circuit upheld EPA’s final rulemaking, and specifically EPA’s Clean Data Policy, in the context of subpart 4. Latino Issues Forum v. EPA, supra. Nos. 06–75831 and 08– 71238 (9th Cir.), Memorandum Opinion, March 2, 2009. In rejecting the petitioner’s challenge to the Clean Data Policy under subpart 4 for PM10, the Ninth Circuit stated, ‘‘As the EPA explained, if an area is in compliance with PM10 standards, then further progress for the purpose of ensuring attainment is not necessary.’’ The general requirements of subpart 1 apply in conjunction with the more specific requirements of subpart 4, to the extent they are not superseded or subsumed by the subpart 4 requirements. Subpart 1 contains general air quality planning requirements for areas designated as nonattainment. See section 172(c). Subpart 4, itself, contains specific planning and scheduling requirements for PM10 nonattainment areas, and under the Court’s January 4, 2013 decision in NRDC v. EPA, these same statutory requirements also apply for PM2.5 nonattainment areas. EPA has longstanding general guidance that interprets the 1990 amendments to the CAA, making recommendations to states for meeting the statutory requirements for SIPs for nonattainment areas. See, ‘‘State Implementation Plans; General Preamble for the Implementation of Title I of the Clear Air Act Amendments of 1990,’’ (57 FR 13498, April 16, 1992) (the ‘‘General Preamble’’). In the General Preamble, EPA discussed the relationship of subpart 1 and subpart 4 SIP requirements, and pointed out that VerDate Mar<15>2010 15:39 Jul 22, 2013 Jkt 229001 subpart 1 requirements were to an extent ‘‘subsumed by, or integrally related to, the more specific PM10 requirements.’’ (57 FR 13538, April 16, 1992). These subpart 1 requirements include, among other things, provisions for attainment demonstrations, RACM, RFP, emissions inventories, and contingency measures. EPA has long interpreted the provisions of subpart 1 (sections 171 and 172) as not requiring the submission of RFP for an area already attaining the ozone NAAQS. For an area that is attaining, showing that the state will make RFP towards attainment ‘‘will, therefore, have no meaning at that point.’’ 57 FR 13564. See 71 FR 40952 and 71 FR 63642 (proposed and final determination of attainment for San Joaquin Valley); 75 FR 13710 and 75 FR 27944 (proposed and final determination of attainment for Coso Junction). Section 189(c)(1) of subpart 4 states that: Plan revisions demonstrating attainment submitted to the Administrator for approval under this subpart shall contain quantitative milestones which are to be achieved every 3 years until the area is redesignated attainment and which demonstrate reasonable further progress, as defined in section [section 171(1)] of this title, toward attainment by the applicable date. With respect to RFP, section 171(1) states that, for purposes of part D, RFP ‘‘means such annual incremental reductions in emissions of the relevant air pollutant as are required by this part or may reasonably be required by the Administrator for the purpose of ensuring attainment of the applicable NAAQS by the applicable date.’’ Thus, whether dealing with the general RFP requirement of section 172(c)(2), the ozone-specific RFP requirements of sections 182(b) and (c), or the specific RFP requirements for PM10 areas of part D, subpart 4, section 189(c)(1), the stated purpose of RFP is to ensure attainment by the applicable attainment date. Although section 189(c) states that revisions shall contain milestones which are to be achieved until the area is redesignated to attainment, such milestones are designed to show reasonable further progress ‘‘toward attainment by the applicable attainment date,’’ as defined by section 171. Thus, it is clear that once the area has attained the standard, no further milestones are necessary or meaningful. This interpretation is supported by language in section 189(c)(3), which mandates that a state that fails to achieve a milestone must submit a plan that assures that the state will achieve the PO 00000 Frm 00040 Fmt 4702 Sfmt 4702 44073 next milestone or attain the NAAQS if there is no next milestone. Section 189(c)(3) assumes that the requirement to submit and achieve milestones does not continue after attainment of the NAAQS. In the General Preamble, EPA noted with respect to section 189(c) that the purpose of the milestone requirement ‘‘is ‘to provide for emission reductions adequate to achieve the standards by the applicable attainment date’ (H.R. Rep.No. 490 101st Cong., 2d Sess. 267 (1990)).’’ (57 FR 13539, April 16, 1992). If an area has in fact attained the standard, the stated purpose of the RFP requirement will have already been fulfilled.4 Similarly, the requirements of section 189(c)(2) with respect to milestones no longer apply so long as an area has attained the standard. Section 189(c)(2) provides in relevant part that: Not later than 90 days after the date on which a milestone applicable to the area occurs, each State in which all or part of such area is located shall submit to the Administrator a demonstration . . . that the milestone has been met. Where the area has attained the standard and there are no further milestones, there is no further requirement to make a submission showing that such milestones have been met. This is consistent with the position that EPA took with respect to the general RFP requirement of section 172(c)(2) in the April 16, 1992 General Preamble and also in the May 10, 1995 EPA memorandum from John S. Seitz, ‘‘Reasonable Further Progress, Attainment Demonstrations, and Related Requirements for the Ozone Nonattainment Areas Meeting the Ozone National Ambient Air Quality Standard,’’ (the ‘‘1995 Seitz memorandum’’) with respect to the requirements of section 182(b) and (c). 4 Thus, EPA believes that it is a distinction without a difference that section 189(c)(1) speaks of the RFP requirement as one to be achieved until an area is ‘‘redesignated attainment,’’ as opposed to section 172(c)(2), which is silent on the period to which the requirement pertains, or the ozone nonattainment area RFP requirements in sections 182(b)(1) or 182(c)(2), which refer to the RFP requirements as applying until the ‘‘attainment date,’’ since section 189(c)(1) defines RFP by reference to section 171(1) of the CAA. Reference to section 171(1) clarifies that, as with the general RFP requirements in section 172(c)(2) and the ozone-specific requirements of section 182(b)(1) and 182(c)(2), the PM-specific requirements may only be required ‘‘for the purpose of ensuring attainment of the applicable national ambient air quality standard by the applicable date.’’ 42 U.S.C. 7501(1). As discussed in the text of this rulemaking, EPA interprets the RFP requirements, in light of the definition of RFP in section 171(1), and incorporated in section 189(c)(1), to be a requirement that no longer applies once the standard has been attained. E:\FR\FM\23JYP1.SGM 23JYP1 44074 Federal Register / Vol. 78, No. 141 / Tuesday, July 23, 2013 / Proposed Rules In the 1995 Seitz memorandum, EPA also noted that section 182(g), the milestone requirement of subpart 2, which is analogous to provisions in section 189(c), is suspended upon a determination that an area has attained. The memorandum, also citing additional provisions related to attainment demonstration and RFP requirements, stated: ehiers on DSK2VPTVN1PROD with PROPOSALS-1 Inasmuch as each of these requirements is linked with the attainment demonstration or RFP requirements of section 182(b)(1) or 182(c)(2), if an area is not subject to the requirement to submit the underlying attainment demonstration or RFP plan, it need not submit the related SIP submission either. See, 1995 Seitz memorandum at 5. With respect to the attainment demonstration requirements of section 172(c) and section 189(a)(1)(B), an analogous rationale leads to the same result. Section 189(a)(1)(B) requires that the plan provide for ‘‘a demonstration (including air quality modeling) that the [SIP] will provide for attainment by the applicable attainment date . . .’’ As with the RFP requirements, if an area is already monitoring attainment of the standard, EPA believes there is no need for an area to make a further submission containing additional measures to achieve attainment. This is also consistent with the interpretation of the section 172(c) requirements provided by EPA in the General Preamble, and the section 182(b) and (c) requirements set forth in the 1995 Seitz memorandum. As EPA stated in the General Preamble, no other measures to provide for attainment would be needed by areas seeking redesignation to attainment since ‘‘attainment will have been reached.’’ 57 FR 13564. Other SIP submission requirements are linked with these attainment demonstration and RFP requirements, and similar reasoning applies to them. These requirements include the contingency measure requirements of sections 172(c)(9). EPA has interpreted the contingency measure requirements of sections 172(c)(9) 5 as no longer applying when an area has attained the standard because those ‘‘contingency measures are directed at ensuring RFP and attainment by the applicable date.’’ 57 FR 13564; 1995 Seitz memorandum, pp. 5–6. Section 172(c)(9) provides that SIPs in nonattainment areas: shall provide for the implementation of specific measures to be undertaken if the area fails to make reasonable further progress, or to attain the [NAAQS] by the attainment date applicable under this part. Such measures 5 And section 182(c)(9) for ozone. VerDate Mar<15>2010 15:39 Jul 22, 2013 Jkt 229001 shall be included in the plan revision as contingency measures to take effect in any such case without further action by the State or [EPA]. The contingency measure requirement is inextricably tied to the reasonable further progress and attainment demonstration requirements. Contingency measures are implemented if reasonable further progress targets are not achieved, or if attainment is not realized by the attainment date. Where an area has already achieved attainment by the attainment date, it has no need to rely on contingency measures to come into attainment or to make further progress to attainment. As EPA stated in the General Preamble: ‘‘The section 172(c)(9) requirements for contingency measures are directed at ensuring RFP and attainment by the applicable date.’’ See 57 FR 13564. Thus these requirements no longer apply when an area has attained the standard. Both sections 172(c)(1) and 189(a)(1)(C) require ‘‘provisions to assure that reasonably available control measures’’ (i.e., RACM) are implemented in a nonattainment area. The General Preamble, (57 FR at 13560, April 16, 1992), states that EPA interprets section 172(c)(1) so that RACM requirements are a ‘‘component’’ of an area’s attainment demonstration. Thus, for the same reason the attainment demonstration no longer applies by its own terms, the requirement for RACM no longer applies. EPA has consistently interpreted this provision to require only implementation of potential RACM measures that could contribute to reasonable further progress or to attainment. General Preamble, 57 FR 13498. Thus, where an area is already attaining the standard, no additional RACM measures are required.6 EPA is interpreting section 189(a)(1)(C) consistent with its interpretation of section 172(c)(1). The suspension of the obligations to submit SIP revisions concerning these RFP, attainment demonstration, RACM, contingency measures and other related requirements exists only for as long as the area continues to monitor attainment of the standard. If EPA determines, after notice-and-comment rulemaking, that the area has monitored a violation of the NAAQS, the basis for the requirements being suspended 6 EPA’s interpretation that the statute requires implementation only of RACM measures that would advance attainment was upheld by the United States Court of Appeals for the Fifth Circuit (Sierra Club v. EPA, 314 F.3d 735, 743–745 (5th Cir. 2002), and by the United States Court of Appeals for the DC Circuit (Sierra Club v. EPA, 294 F.3d 155, 162– 163 (DC Cir. 2002)). PO 00000 Frm 00041 Fmt 4702 Sfmt 4702 would no longer exist. In that case, the area would again be subject to a requirement to submit the pertinent SIP revision or revisions and would need to address those requirements. Thus, a final determination that the area need not submit one of the pertinent SIP submittals amounts to no more than a suspension of the requirements for so long as the area continues to attain the standard. Only if and when EPA redesignates the area to attainment would the area be relieved of these submission obligations. Attainment determinations under the Clean Data Policy do not shield an area from obligations unrelated to attainment in the area, such as provisions to address pollution transport. As set forth previously, based on our proposed determination that the Liberty-Clairton Area is currently attaining the 1997 annual PM2.5 NAAQS, EPA proposes to find that the obligations to submit planning provisions to meet the requirements for an attainment demonstration, reasonable further progress plans, reasonably available control measures, and contingency measures are suspended for so long as the area continues to monitor attainment of the 1997 annual PM2.5 NAAQS. If in the future, EPA determines after notice-andcomment rulemaking that the area again violates the 1997 annual PM2.5 NAAQS, the basis for suspending the attainment demonstration, RFP, RACM, and contingency measure obligations would no longer exist. V. Determination of Attainment by the Attainment Date As stated previously, in light of the Court’s decision and its remand of the Implementation Rule, EPA in this proposed rulemaking action addresses the effect of a final determination of attainment for the Liberty-Clairton Area, as if that area were considered a moderate nonattainment area under subpart 4. Pursuant to CAA section 188(c)(1), the 1997 annual PM2.5 NAAQS attainment date for moderate areas is as expeditiously as practicable, but not later than the end of the sixth calendar year after the area’s designation as nonattainment. For the purposes of evaluating attainment by attainment date, the attainment date for the Liberty-Clairton Area is December 31, 2011. Under CAA section 188(b)(2), EPA is required to make a determination that a nonattainment area has attained by its attainment date, and publish that determination in the Federal Register. If EPA determines that any moderate area is not in attainment after its applicable E:\FR\FM\23JYP1.SGM 23JYP1 Federal Register / Vol. 78, No. 141 / Tuesday, July 23, 2013 / Proposed Rules ehiers on DSK2VPTVN1PROD with PROPOSALS-1 attainment date, that area is reclassified to serious by operation of law. EPA is proposing to make a determination that the Liberty-Clairton Area attained the 1997 annual PM2.5 NAAQS by the applicable attainment date of December 31, 2011. Therefore, EPA has met the requirement of CAA section 188(b)(2) to determine, based on the area’s air quality as of the attainment date, whether the area attained the standard by that date. The effect of a final determination of attainment by the area’s attainment date would be to discharge EPA’s obligation under CAA section 188(b)(2). VI. Proposed Actions Pursuant to sections 188(b)(2) of the CAA, EPA is proposing to determine that the Liberty-Clairton Area has attained the 1997 annual PM2.5 NAAQS by its attainment date, December 31, 2011. Separately and independently, EPA is proposing to determine, based on the most recent three years of qualityassured and certified data meeting the requirements of 40 CFR part 50, appendix N, that the Liberty-Clairton Area is currently attaining the 1997 annual PM2.5 NAAQS. In conjunction with and based upon our proposed determination that the Liberty-Clairton Area has attained and is currently attaining the standard, EPA proposes to determine that the obligation to submit the following attainment-related planning requirements is not applicable for so long as the area continues to attain the PM2.5 standard: The part D, subpart 4 obligations to provide an attainment demonstration pursuant to section 189(a)(1)(B), the RACM provisions of section 189(a)(1)(C), the RFP provisions of section 189(c), and related attainment demonstration, RACM, RFP, and contingency measure provisions requirements of subpart 1, section 172. This proposed rulemaking action, if finalized, would not constitute a redesignation to attainment under CAA section 107(d)(3). These proposed determinations are based upon quality-assured, and certified ambient air monitoring data that show the area has monitored attainment of the 1997 annual PM2.5 NAAQS for the 2009–2011 and 2010– 2012 monitoring periods. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action. VII. Statutory and Executive Order Reviews This rulemaking action proposes to make determinations of attainment based on air quality, and would, if VerDate Mar<15>2010 15:39 Jul 22, 2013 Jkt 229001 finalized, result in the suspension of certain federal requirements, and would not impose additional requirements beyond those imposed by state law. For that reason, these proposed determinations of attainment: • Are not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); • do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • are 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.); • do not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • do not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • are not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • are not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • are 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 • do 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). In addition, this proposed rule, proposing to determine that the LibertyClairton Area has attained the 1997 annual PM2.5 NAAQS, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

ACTION: Notice of Data Availability (NODA). AGENCY: This Notice provides an opportunity to comment on EPA’s draft analysis of the lifecycle greenhouse gas (GHG) emissions of ethanol that is produced using barley as a feedstock. EPA’s draft analysis indicates that ethanol produced from barley has an estimated lifecycle GHG emissions reduction of 47% as compared to baseline conventional fuel when the barley ethanol is produced at a dry mill facility that uses natural gas for all process energy, uses electricity from the grid, and dries up to 100% of distillers grains. Such barley ethanol would therefore meet the minimum 20% GHG emissions reduction threshold for conventional biofuels under the Clean Air Act Renewable Fuel Standard (RFS) program. In addition, EPA analyzed two potential options for producing barley ethanol that would meet the 50% GHG emissions reduction threshold for advanced biofuels. Ethanol produced from dry-milling barley meet the advanced biofuels GHG reduction threshold if it is produced at a facility that uses no more than 30,700 Btu of natural gas for process energy, no more than 4,200 Btu of biomass from barley hulls or biogas from landfills, waste treatment plants, barley hull digesters, or waste digesters for process energy, and no more than 0.84 kWh of electricity from the grid for all electricity used at the renewable fuel production facility, calculated on a per gallon basis. Ethanol produced from dry-milling barley can also meet the advanced biofuel GHG reduction threshold if the production facility uses no more than 36,800 Btu of natural gas for process energy and also uses natural gas for on-site production of all electricity used at the facility other than up to 0.19 kWh of electricity from the grid, calculated on a per gallon basis.

Particulate Standards for the Liberty-Clairton Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to make two separate and independent
determinations regarding the Liberty-Clairton, Pennsylvania 1997 annual
fine particulate (PM2.5) nonattainment area (the Liberty-
Clairton Area). First, EPA is proposing to determine that the Liberty-
Clairton Area attained the 1997 PM2.5 annual national
ambient air quality standards (NAAQS) by the applicable attainment
date, December 31, 2011. This proposed determination is based on
quality assured and certified ambient air quality date for the 2009-
2011 monitoring period. Second, EPA is proposing that the Liberty-
Clairton Area has continued to attain the 1997 annual PM2.5
NAAQS, based on quality-assured and certified ambient air quality data
for the 2010-2012 monitoring period. If EPA finalizes this latter
``clean data determination,'' the requirement for the Liberty-Clairton
Area to submit an attainment demonstration, reasonably available
control measures (RACM), reasonable further progress (RFP), and
contingency measures related to attainment of the 1997 annual
PM2.5 NAAQS would be suspended for so long as the area
continues to attain the 1997 annual PM2.5 NAAQS. These
determinations do not constitute a redesignation to attainment. The
Liberty-Clairton Area will remain designated nonattainment for the 1997
annual PM2.5 NAAQS until such time as EPA determines that
the Liberty-Clairton Area meets the Clean Air Act (CAA) requirements
for redesignation to attainment, including an approved maintenance
plan. These proposed actions are being taken under the CAA.

SUPPLEMENTARY INFORMATION:

I. Summary of Proposed Actions

EPA is proposing two separate and independent determinations
regarding the Liberty-Clairton Area. First, pursuant to section
188(b)(2) of the CAA, EPA is proposing to make a determination that the
Liberty-Clairton Area attained the 1997 annual PM2.5 NAAQS
by the applicable attainment date, December 31, 2011. This proposed
determination is based upon quality-assured and certified ambient air
monitoring data for the 2009-2011 monitoring period that shows the area
has monitored attainment of the 1997 PM2.5 annual NAAQS as
of its attainment date.
EPA is also proposing to make a determination that the Liberty-
Clairton Area continues to attain the 1997 annual PM2.5
NAAQS. This proposed ``clean data'' determination is based upon quality
assured and certified ambient air monitoring data that show the area
has monitored attainment of the 1997 PM2.5 NAAQS for the
2010-2012 monitoring period. If EPA finalizes this determination, the
requirement for the Liberty-Clairton Area to submit an attainment
demonstration, RACM, RFP, and contingency measures related to
attainment of the 1997 annual PM2.5 NAAQS shall be suspended
for so long as the area continues to attain that NAAQS.\1\
---------------------------------------------------------------------------

\1\ Even if these requirements are suspended, EPA is not
precluded from acting upon these elements at any time if submitted
to EPA for review and approval. On June 17, 2011, the Commonwealth
of Pennsylvania submitted a SIP revision for the Liberty-Clairton
Area to EPA for review and approval. On November 7, 2011 (76 FR
68699), EPA proposed approval, with one condition, of Pennsylvania's
SIP revision for the Liberty-Clairton Area.
---------------------------------------------------------------------------

II. Background

A. The PM2.5 NAAQS

On July 18, 1997 (62 FR 38652), EPA established a health-based
PM2.5 NAAQS at 15.0 micrograms per cubic meter ([micro]g/
m\3\) based on a 3-year average of annual mean PM2.5
concentrations (``the 1997 annual PM2.5 NAAQS'' or ``the
1997 annual standard''). At that time, EPA also established a 24-hour
standard of 65 [micro]g/m\3\ (the ``1997 24-hour standard''). See 40
CFR 50.7. On October 17, 2006 (71 FR 61144), EPA retained the 1997
annual PM2.5 NAAQS at 15 [micro]g/m\3\ based on a 3-year
average

[[Page 44071]]

of annual mean PM2.5 concentrations, and promulgated a 24-
hour standard of 35 [micro]g/m\3\ based on a 3-year average of the 98th
percentile of 24-hour concentrations (the ``2006 24-hour standard'').
In response to legal challenges of the 2006 annual standard, the U.S.
Court of Appeals for the District of Columbia Circuit (D.C. Circuit or
the Court) remanded this standard to EPA for further consideration.
See, American Farm Bureau Federation and National Pork Producers
Council, et al. v. EPA, 559 F.3d 512 (D.C. Circuit 2009). However,
given that the 1997 and 2006 annual PM2.5 standards are
essentially identical, attainment of the 1997 annual standard would
also indicate attainment of the remanded 2006 annual standard.
On December 14, 2012 (78 FR 3086), EPA lowered the primary annual
PM2.5 NAAQS from 15 to 12.0 [mu]g/m\3\. EPA retained the
2006 24-hour PM2.5 NAAQS, and the 1997 secondary annual
PM2.5 NAAQS. EPA also retained the existing standards for
coarse particle pollution (PM10). This rulemaking action
proposes determinations solely for the 1997 annual PM2.5
standard. It does not address the 1997 or 2006 24-hour PM2.5
standards or the 2012 PM2.5 annual NAAQS.

B. The Liberty-Clairton Area

On January 5, 2005 (70 FR 944), EPA published its air quality
designations for the 1997 PM2.5 NAAQS based upon air quality
monitoring data for calendar years 2001-2003. These designations became
effective on April 5, 2005. The Liberty-Clairton Area is comprised of
the boroughs of Lincoln, Glassport, Liberty, and Port Vue and the City
of Clairton, all in Allegheny County, Pennsylvania. See 40 CFR 81.339.
The Liberty-Clairton Area is surrounded by, but separate and distinct
from the Pittsburgh-Beaver Valley PM2.5 nonattainment area.
On November 13, 2009 (74 FR 58688), EPA published the area
designations for the 2006 24-hour standard. That action, effective on
December 14, 2009, designated the same Liberty-Clairton Area as
nonattainment for the 2006 24-hour standard and clarified that the
Liberty-Clairton Area is designated as unclassifiable/attainment for
the 1997 24-hour PM2.5 standard.

III. EPA's Analysis of the Relevant Air Quality Data

The Commonwealth of Pennsylvania submitted quality assured air
quality monitoring data into the EPA Air Quality System (AQS) database
for the 2009-2011 and 2010-2012 monitoring periods. Pennsylvania then
certified that data. EPA's evaluation of this data shows that the
Liberty-Clairton Area has attained the 1997 annual PM2.5
NAAQS by its 2011 attainment date, and that it continues to attain the
1997 annual PM2.5 NAAQS. Additional information on air
quality data for the Liberty-Clairton Area can be found in the
technical support document (TSD) prepared for this action.
The criteria for determining if an area is attaining the 1997
annual PM2.5 NAAQS are set out in 40 CFR 50.13 and appendix
N. The 1997 annual PM2.5 NAAQS is met when the annual design
value is less than or equal to 15.0 [micro]g/m\3\. Three years of valid
annual means are required to produce a valid annual standard design
value. A year meets data completeness requirements when at least 75
percent of the scheduled sampling days for each quarter have valid
data. The use of less than complete data is subject to the approval of
EPA, which may consider factors such as monitoring site closures/moves,
monitoring diligence, and nearby concentrations in determining whether
to use such data.
There are two PM2.5 monitors in the Liberty-Clairton
Area--one in Liberty Borough and one in the City of Clairton. Both
monitors had complete data for all quarters in the years 2009 through
2012, except for one calendar quarter in 2011 when the Clairton monitor
had less than complete data capture due to unreliable data results via
laboratory analysis.
For this monitor, EPA performed a statistical analysis of the data,
in which a linear regression relationship is established between the
site with incomplete data and a nearby site which has more complete
data in the period in which the incomplete site is missing data. The
linear regression relationship is based on time periods in which both
monitors were operating. The linear regression equation developed from
the relationship between the monitors is used to fill in missing data
for the incomplete monitor, so that the normal data completeness
requirement of 75 percent of data in each quarter of the three years is
met. After the missing data for the site is filled in, the results are
verified through an additional statistical test. The results of EPA's
statistical analysis indicated that while the Liberty monitor had less
than complete data, the data is sufficient to demonstrate that the
NAAQS has been met. Details of this analysis are set out in the TSD
prepared for this action.
This proposed determination of attainment for the Liberty-Clairton
Area is based on EPA's evaluation of quality-controlled, quality
assured, certified annual PM2.5 air quality data for the
2009-2011 and 2010-2012 monitoring periods. The monitoring data and
calculated design values for Liberty-Clairton Area are summarized in
Table 1 for the 2009-2011 monitoring period, and in Table 2 for the
2010-2012 monitoring period.

Consistent with the requirements contained in 40 CFR part 50, EPA
has reviewed the PM2.5 ambient air monitoring data for the
monitoring periods 2009-2011 and 2010-2012 for the Liberty-Clairton
Area, as recorded in the AQS database. On the basis of that review, EPA
proposes to determine that the Liberty-Clairton Area (1) attained the
1997 annual PM2.5 NAAQS by its attainment date, based on
data for the 2009-2011 monitoring period, and (2) continued to attain
during the 2010-2012 monitoring period.

IV. Effect of Proposed Determinations of Attainment for 1997
PM2.5 NAAQS Under Subpart 4 of Part D of Title I of the CAA
(Subpart 4)

This section and section V of EPA's proposal address the effects of
a final clean data determination and a final determination of
attainment by the attainment date for the Liberty-Clairton Area. For
the 1997 annual PM2.5 standard, 40 CFR 51.004 of EPA's
Implementation Rule for the 1997 annual PM2.5 standard
embodies EPA's ``Clean Data Policy'' interpretation under subpart 1 of
Part D of Title I of the CAA (subpart 1). The provisions of 40 CFR
51.004 set forth the effects of a determination of attainment for the
1997 PM2.5 standard. (72 FR 20585, 20665, April 25, 2007).
On January 4, 2013, in Natural Resources Defense Council v. EPA,
the DC Circuit remanded to EPA the ``Final Clean Air Fine Particle
Implementation Rule'' (72 FR 20586, April 25, 2007) and the
``Implementation of the New Source Review (NSR) Program for Particulate
Matter Less than 2.5 Micrometers (PM2.5)'' final rule (73 FR
28321, May 16, 2008) (collectively, ``1997 PM2.5
Implementation Rule'' or ``Implementation Rule''). 706 F.3d 428 (D.C.
Cir. 2013). The Court found that EPA erred in implementing the 1997
PM2.5 NAAQS pursuant solely to the general implementation
provisions of subpart 1, rather than the particulate-matter-specific
provisions of subpart 4. The Court remanded EPA's Implementation Rule
for further proceedings consistent with the Court's decision. In light
of the Court's decision and its remand of the Implementation Rule, EPA
in this proposed rulemaking action addresses the effect of a final
determination of attainment for the Liberty-Clairton Area, as if that
area were considered a moderate nonattainment area under subpart 4.\2\
As set forth in more detail below, under EPA's Clean Data Policy
interpretation, a determination that the area has attained the standard
suspends the state's obligation to submit attainment-related planning
requirements of 4 (and the applicable provisions of subpart 1) for so
long as the area continues to attain the standard. These include
requirements to submit an attainment demonstration, RFP, RACM, and
contingency measures, because the purpose of these provisions is to
help reach attainment, a goal which has already been achieved.
---------------------------------------------------------------------------

\2\ For the purposes of evaluating the effects of this proposed
determination of attainment under subpart 4, EPA is considering the
Liberty-Clairton Area to be a ``moderate'' PM2.5
nonattainment area. Under section 188 of the CAA, all areas
designated nonattainment areas under subpart 4 would initially be
classified by operation of law as ``moderate'' nonattainment areas,
and would remain moderate nonattainment areas unless and until EPA
reclassifies the area as a ``serious'' nonattainment area.
Accordingly, EPA believes that it is appropriate to limit the
evaluation of the potential impact of subpart 4 requirements to
those that would be applicable to moderate nonattainment areas.
Sections 189(a) and (c) of subpart 4 apply to moderate nonattainment
areas and include an attainment demonstration (section
189(a)(1)(B)); (3) provisions for RACM (section 189(a)(1)(C)); and
quantitative milestones demonstrating RFP toward attainment by the
applicable attainment date (section 189(c)). In addition, EPA also
evaluates the applicable requirements of subpart 1.
---------------------------------------------------------------------------

A. Background on Clean Data Policy

Over the past two decades, EPA has consistently applied its ``Clean
Data Policy'' interpretation to attainment-related provisions of
subparts 1, 2 and 4. The Clean Data Policy is the subject of several
EPA memoranda and regulations. In addition, numerous individual
rulemakings published in the Federal Register have applied the
interpretation to a spectrum of NAAQS, including the 1-hour and 1997
ozone, PM10, PM2.5, carbon monoxide (CO) and lead
(Pb) standards. The D.C. Circuit has upheld the Clean Data Policy
interpretation as embodied in EPA's 1997 8-Hour Ozone Implementation
Rule, 40 CFR 51.918.\3\ NRDC v. EPA, 571 F. 3d 1245 (D.C. Cir. 2009).
Other U.S. Circuit Courts of Appeals that have considered and reviewed
EPA's Clean Data Policy interpretation have upheld it and the
rulemakings applying EPA's interpretation. Sierra Club v. EPA, 99 F.3d
1551 (10th Cir. 1996); Sierra Club v. EPA, 375 F. 3d 537 (7th Cir.
2004); Our Children's Earth Foundation v. EPA, N. 04-73032 (9th Cir.
June 28, 2005) (memorandum opinion), Latino Issues Forum, v. EPA, Nos.
06-75831 and 08-71238 (9th Cir.), Memorandum Opinion, March 2, 2009.
---------------------------------------------------------------------------

\3\ ``EPA's Final Rule to implement the 8-Hour Ozone National
Ambient Air Quality Standard-Phase 2 (Phase 2 Final Rule)'' (70 FR
71612, 71645-46, November 29, 2005).
---------------------------------------------------------------------------

As noted above, EPA incorporated its Clean Data Policy
interpretation in both its 8-Hour Ozone Implementation Rule and in its
PM2.5 Implementation Rule in 40 CFR 51.1004(c). (72 FR
20585, 20665, April 25, 2007). While the D.C. Circuit, in its January
4, 2013 decision, remanded the 1997 PM2.5 Implementation
Rule, the Court did not address the merits of that regulation, nor cast
doubt on EPA's existing interpretation of the statutory provisions.
However, in light of the Court's decision, EPA's Clean Data Policy
interpretation under subpart 4 is set forth here, for the purpose of
identifying the effects of a determination of attainment for the 1997
annual PM2.5 standard for the Liberty-Clairton Area. EPA has
previously articulated its Clean Data interpretation under subpart 4 in
implementing the PM10 standard. See, e.g., (75 FR 27944, May
19, 2010) (determination of attainment of the PM10 standard
in Coso Junction, California); (75 FR 6571, February 10, 2010), (71 FR
6352, February 8, 2006)

[[Page 44073]]

(Ajo, Arizona Area); (71 FR 13021, March 14, 2006) (Yuma, Arizona
Area); (71 FR 40023, July 14, 2006) (Weirton, West Virginia Area); (71
FR 44920, August 8, 2006) (Rillito, Arizona Area); (71 FR 63642,
October 30, 2006) (San Joaquin Valley, California Area); (72 FR 14422,
March 28, 2007) (Miami, Arizona Area); (75 FR 27944, May 19, 2010)
(Coso Junction, California Area). Thus EPA has established that, under
subpart 4, an attainment determination suspends the obligations to
submit an attainment demonstration, RACM, RFP contingency measures, and
other measures related to attainment.

B. Application of the Clean Data Policy to Attainment-Related
Provisions of Subpart 4

In EPA's proposed and final rulemaking actions determining that the
San Joaquin Valley nonattainment area attained the PM10
standard, EPA set forth at length its rationale for applying the Clean
Data Policy to PM10 under subpart 4. The Ninth Circuit
upheld EPA's final rulemaking, and specifically EPA's Clean Data
Policy, in the context of subpart 4. Latino Issues Forum v. EPA, supra.
Nos. 06-75831 and 08-71238 (9th Cir.), Memorandum Opinion, March 2,
2009. In rejecting the petitioner's challenge to the Clean Data Policy
under subpart 4 for PM10, the Ninth Circuit stated, ``As the
EPA explained, if an area is in compliance with PM10
standards, then further progress for the purpose of ensuring attainment
is not necessary.''
The general requirements of subpart 1 apply in conjunction with the
more specific requirements of subpart 4, to the extent they are not
superseded or subsumed by the subpart 4 requirements. Subpart 1
contains general air quality planning requirements for areas designated
as nonattainment. See section 172(c). Subpart 4, itself, contains
specific planning and scheduling requirements for PM10
nonattainment areas, and under the Court's January 4, 2013 decision in
NRDC v. EPA, these same statutory requirements also apply for
PM2.5 nonattainment areas. EPA has longstanding general
guidance that interprets the 1990 amendments to the CAA, making
recommendations to states for meeting the statutory requirements for
SIPs for nonattainment areas. See, ``State Implementation Plans;
General Preamble for the Implementation of Title I of the Clear Air Act
Amendments of 1990,'' (57 FR 13498, April 16, 1992) (the ``General
Preamble''). In the General Preamble, EPA discussed the relationship of
subpart 1 and subpart 4 SIP requirements, and pointed out that subpart
1 requirements were to an extent ``subsumed by, or integrally related
to, the more specific PM10 requirements.'' (57 FR 13538,
April 16, 1992). These subpart 1 requirements include, among other
things, provisions for attainment demonstrations, RACM, RFP, emissions
inventories, and contingency measures.
EPA has long interpreted the provisions of subpart 1 (sections 171
and 172) as not requiring the submission of RFP for an area already
attaining the ozone NAAQS. For an area that is attaining, showing that
the state will make RFP towards attainment ``will, therefore, have no
meaning at that point.'' 57 FR 13564. See 71 FR 40952 and 71 FR 63642
(proposed and final determination of attainment for San Joaquin
Valley); 75 FR 13710 and 75 FR 27944 (proposed and final determination
of attainment for Coso Junction).
Section 189(c)(1) of subpart 4 states that:

Plan revisions demonstrating attainment submitted to the
Administrator for approval under this subpart shall contain
quantitative milestones which are to be achieved every 3 years until
the area is redesignated attainment and which demonstrate reasonable
further progress, as defined in section [section 171(1)] of this
title, toward attainment by the applicable date.

With respect to RFP, section 171(1) states that, for purposes of
part D, RFP ``means such annual incremental reductions in emissions of
the relevant air pollutant as are required by this part or may
reasonably be required by the Administrator for the purpose of ensuring
attainment of the applicable NAAQS by the applicable date.'' Thus,
whether dealing with the general RFP requirement of section 172(c)(2),
the ozone-specific RFP requirements of sections 182(b) and (c), or the
specific RFP requirements for PM10 areas of part D, subpart
4, section 189(c)(1), the stated purpose of RFP is to ensure attainment
by the applicable attainment date.
Although section 189(c) states that revisions shall contain
milestones which are to be achieved until the area is redesignated to
attainment, such milestones are designed to show reasonable further
progress ``toward attainment by the applicable attainment date,'' as
defined by section 171. Thus, it is clear that once the area has
attained the standard, no further milestones are necessary or
meaningful. This interpretation is supported by language in section
189(c)(3), which mandates that a state that fails to achieve a
milestone must submit a plan that assures that the state will achieve
the next milestone or attain the NAAQS if there is no next milestone.
Section 189(c)(3) assumes that the requirement to submit and achieve
milestones does not continue after attainment of the NAAQS.
In the General Preamble, EPA noted with respect to section 189(c)
that the purpose of the milestone requirement ``is `to provide for
emission reductions adequate to achieve the standards by the applicable
attainment date' (H.R. Rep.No. 490 101st Cong., 2d Sess. 267 (1990)).''
(57 FR 13539, April 16, 1992). If an area has in fact attained the
standard, the stated purpose of the RFP requirement will have already
been fulfilled.\4\
---------------------------------------------------------------------------

\4\ Thus, EPA believes that it is a distinction without a
difference that section 189(c)(1) speaks of the RFP requirement as
one to be achieved until an area is ``redesignated attainment,'' as
opposed to section 172(c)(2), which is silent on the period to which
the requirement pertains, or the ozone nonattainment area RFP
requirements in sections 182(b)(1) or 182(c)(2), which refer to the
RFP requirements as applying until the ``attainment date,'' since
section 189(c)(1) defines RFP by reference to section 171(1) of the
CAA. Reference to section 171(1) clarifies that, as with the general
RFP requirements in section 172(c)(2) and the ozone-specific
requirements of section 182(b)(1) and 182(c)(2), the PM-specific
requirements may only be required ``for the purpose of ensuring
attainment of the applicable national ambient air quality standard
by the applicable date.'' 42 U.S.C. 7501(1). As discussed in the
text of this rulemaking, EPA interprets the RFP requirements, in
light of the definition of RFP in section 171(1), and incorporated
in section 189(c)(1), to be a requirement that no longer applies
once the standard has been attained.
---------------------------------------------------------------------------

Similarly, the requirements of section 189(c)(2) with respect to
milestones no longer apply so long as an area has attained the
standard. Section 189(c)(2) provides in relevant part that:

Not later than 90 days after the date on which a milestone
applicable to the area occurs, each State in which all or part of
such area is located shall submit to the Administrator a
demonstration . . . that the milestone has been met.

Where the area has attained the standard and there are no further
milestones, there is no further requirement to make a submission
showing that such milestones have been met. This is consistent with the
position that EPA took with respect to the general RFP requirement of
section 172(c)(2) in the April 16, 1992 General Preamble and also in
the May 10, 1995 EPA memorandum from John S. Seitz, ``Reasonable
Further Progress, Attainment Demonstrations, and Related Requirements
for the Ozone Nonattainment Areas Meeting the Ozone National Ambient
Air Quality Standard,'' (the ``1995 Seitz memorandum'') with respect to
the requirements of section 182(b) and (c).

[[Page 44074]]

In the 1995 Seitz memorandum, EPA also noted that section 182(g), the
milestone requirement of subpart 2, which is analogous to provisions in
section 189(c), is suspended upon a determination that an area has
attained. The memorandum, also citing additional provisions related to
attainment demonstration and RFP requirements, stated:

Inasmuch as each of these requirements is linked with the
attainment demonstration or RFP requirements of section 182(b)(1) or
182(c)(2), if an area is not subject to the requirement to submit
the underlying attainment demonstration or RFP plan, it need not
submit the related SIP submission either.

See, 1995 Seitz memorandum at 5.
With respect to the attainment demonstration requirements of
section 172(c) and section 189(a)(1)(B), an analogous rationale leads
to the same result. Section 189(a)(1)(B) requires that the plan provide
for ``a demonstration (including air quality modeling) that the [SIP]
will provide for attainment by the applicable attainment date . . .''
As with the RFP requirements, if an area is already monitoring
attainment of the standard, EPA believes there is no need for an area
to make a further submission containing additional measures to achieve
attainment. This is also consistent with the interpretation of the
section 172(c) requirements provided by EPA in the General Preamble,
and the section 182(b) and (c) requirements set forth in the 1995 Seitz
memorandum. As EPA stated in the General Preamble, no other measures to
provide for attainment would be needed by areas seeking redesignation
to attainment since ``attainment will have been reached.'' 57 FR 13564.
Other SIP submission requirements are linked with these attainment
demonstration and RFP requirements, and similar reasoning applies to
them. These requirements include the contingency measure requirements
of sections 172(c)(9). EPA has interpreted the contingency measure
requirements of sections 172(c)(9) \5\ as no longer applying when an
area has attained the standard because those ``contingency measures are
directed at ensuring RFP and attainment by the applicable date.'' 57 FR
13564; 1995 Seitz memorandum, pp. 5-6.
---------------------------------------------------------------------------

\5\ And section 182(c)(9) for ozone.
---------------------------------------------------------------------------

Section 172(c)(9) provides that SIPs in nonattainment areas:

shall provide for the implementation of specific measures to be
undertaken if the area fails to make reasonable further progress, or
to attain the [NAAQS] by the attainment date applicable under this
part. Such measures shall be included in the plan revision as
contingency measures to take effect in any such case without further
action by the State or [EPA].

The contingency measure requirement is inextricably tied to the
reasonable further progress and attainment demonstration requirements.
Contingency measures are implemented if reasonable further progress
targets are not achieved, or if attainment is not realized by the
attainment date. Where an area has already achieved attainment by the
attainment date, it has no need to rely on contingency measures to come
into attainment or to make further progress to attainment. As EPA
stated in the General Preamble: ``The section 172(c)(9) requirements
for contingency measures are directed at ensuring RFP and attainment by
the applicable date.'' See 57 FR 13564. Thus these requirements no
longer apply when an area has attained the standard.
Both sections 172(c)(1) and 189(a)(1)(C) require ``provisions to
assure that reasonably available control measures'' (i.e., RACM) are
implemented in a nonattainment area. The General Preamble, (57 FR at
13560, April 16, 1992), states that EPA interprets section 172(c)(1) so
that RACM requirements are a ``component'' of an area's attainment
demonstration. Thus, for the same reason the attainment demonstration
no longer applies by its own terms, the requirement for RACM no longer
applies. EPA has consistently interpreted this provision to require
only implementation of potential RACM measures that could contribute to
reasonable further progress or to attainment. General Preamble, 57 FR
13498. Thus, where an area is already attaining the standard, no
additional RACM measures are required.\6\ EPA is interpreting section
189(a)(1)(C) consistent with its interpretation of section 172(c)(1).
---------------------------------------------------------------------------

\6\ EPA's interpretation that the statute requires
implementation only of RACM measures that would advance attainment
was upheld by the United States Court of Appeals for the Fifth
Circuit (Sierra Club v. EPA, 314 F.3d 735, 743-745 (5th Cir. 2002),
and by the United States Court of Appeals for the DC Circuit (Sierra
Club v. EPA, 294 F.3d 155, 162-163 (DC Cir. 2002)).
---------------------------------------------------------------------------

The suspension of the obligations to submit SIP revisions
concerning these RFP, attainment demonstration, RACM, contingency
measures and other related requirements exists only for as long as the
area continues to monitor attainment of the standard. If EPA
determines, after notice-and-comment rulemaking, that the area has
monitored a violation of the NAAQS, the basis for the requirements
being suspended would no longer exist. In that case, the area would
again be subject to a requirement to submit the pertinent SIP revision
or revisions and would need to address those requirements. Thus, a
final determination that the area need not submit one of the pertinent
SIP submittals amounts to no more than a suspension of the requirements
for so long as the area continues to attain the standard. Only if and
when EPA redesignates the area to attainment would the area be relieved
of these submission obligations. Attainment determinations under the
Clean Data Policy do not shield an area from obligations unrelated to
attainment in the area, such as provisions to address pollution
transport.
As set forth previously, based on our proposed determination that
the Liberty-Clairton Area is currently attaining the 1997 annual
PM2.5 NAAQS, EPA proposes to find that the obligations to
submit planning provisions to meet the requirements for an attainment
demonstration, reasonable further progress plans, reasonably available
control measures, and contingency measures are suspended for so long as
the area continues to monitor attainment of the 1997 annual
PM2.5 NAAQS. If in the future, EPA determines after notice-
and-comment rulemaking that the area again violates the 1997 annual
PM2.5 NAAQS, the basis for suspending the attainment
demonstration, RFP, RACM, and contingency measure obligations would no
longer exist.

V. Determination of Attainment by the Attainment Date

As stated previously, in light of the Court's decision and its
remand of the Implementation Rule, EPA in this proposed rulemaking
action addresses the effect of a final determination of attainment for
the Liberty-Clairton Area, as if that area were considered a moderate
nonattainment area under subpart 4. Pursuant to CAA section 188(c)(1),
the 1997 annual PM2.5 NAAQS attainment date for moderate
areas is as expeditiously as practicable, but not later than the end of
the sixth calendar year after the area's designation as nonattainment.
For the purposes of evaluating attainment by attainment date, the
attainment date for the Liberty-Clairton Area is December 31, 2011.
Under CAA section 188(b)(2), EPA is required to make a determination
that a nonattainment area has attained by its attainment date, and
publish that determination in the Federal Register. If EPA determines
that any moderate area is not in attainment after its applicable

[[Page 44075]]

attainment date, that area is reclassified to serious by operation of
law.
EPA is proposing to make a determination that the Liberty-Clairton
Area attained the 1997 annual PM2.5 NAAQS by the applicable
attainment date of December 31, 2011. Therefore, EPA has met the
requirement of CAA section 188(b)(2) to determine, based on the area's
air quality as of the attainment date, whether the area attained the
standard by that date. The effect of a final determination of
attainment by the area's attainment date would be to discharge EPA's
obligation under CAA section 188(b)(2).

VI. Proposed Actions

Pursuant to sections 188(b)(2) of the CAA, EPA is proposing to
determine that the Liberty-Clairton Area has attained the 1997 annual
PM2.5 NAAQS by its attainment date, December 31, 2011.
Separately and independently, EPA is proposing to determine, based on
the most recent three years of quality-assured and certified data
meeting the requirements of 40 CFR part 50, appendix N, that the
Liberty-Clairton Area is currently attaining the 1997 annual
PM2.5 NAAQS. In conjunction with and based upon our proposed
determination that the Liberty-Clairton Area has attained and is
currently attaining the standard, EPA proposes to determine that the
obligation to submit the following attainment-related planning
requirements is not applicable for so long as the area continues to
attain the PM2.5 standard: The part D, subpart 4 obligations
to provide an attainment demonstration pursuant to section
189(a)(1)(B), the RACM provisions of section 189(a)(1)(C), the RFP
provisions of section 189(c), and related attainment demonstration,
RACM, RFP, and contingency measure provisions requirements of subpart
1, section 172. This proposed rulemaking action, if finalized, would
not constitute a redesignation to attainment under CAA section
107(d)(3).
These proposed determinations are based upon quality-assured, and
certified ambient air monitoring data that show the area has monitored
attainment of the 1997 annual PM2.5 NAAQS for the 2009-2011
and 2010-2012 monitoring periods. EPA is soliciting public comments on
the issues discussed in this document. These comments will be
considered before taking final action.

VII. Statutory and Executive Order Reviews

This rulemaking action proposes to make determinations of
attainment based on air quality, and would, if finalized, result in the
suspension of certain federal requirements, and would not impose
additional requirements beyond those imposed by state law. For that
reason, these proposed determinations of attainment:
Are not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
do not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
are 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.);
do not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
are not an economically significant regulatory action
based on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
are not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
are 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
do 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).
In addition, this proposed rule, proposing to determine that the
Liberty-Clairton Area has attained the 1997 annual PM2.5
NAAQS, does not have tribal implications as specified by Executive
Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not
approved to apply in Indian country located in the state, and EPA notes
that it will not impose substantial direct costs on tribal governments
or preempt tribal law.
