3 TABLE OF CONTENTS I. Background Information
II. Pu blic Comments and EPA Responses III. Final Action IV. Statutory and Executive Order Reviews I. Background Information
On October 20, 2015, we proposed to approve state implementation plan (SIP) revisions submitted by California to address Clean Air Act (CAA or Act) requirements for the 2006 24

- hour fine particulate matter (PM 2.5 ) national ambient air quality standard s (NAA QS) in the Lo s Angeles

South Coast air basin (South Coast ) Moderate PM 2.5 nonattainment area. See 80 FR 63640 (October 20 , 2015). The SIP revisions that we proposed to approve are th ose portions of the “Final 2012 Air Quality Management Plan (AQMP)” that address attain ment of the 2006 PM 2.5 NAAQS ( 2012 PM 2.5 Plan ) , submitted February 13 , 2013, and the “Supplement to the 24

- Hour PM 2.5 State Implementation Plan for the South Coast Air Basin” ( 2015 Supplement ) , submitted March 4, 2015
. We refer to these submissions collectively herein as “the Plan.” The EPA proposed to approve the following elements of the Plan as satisfying applicable CAA requirements : (1) the 2008 base year emissions inventories;This documen t is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on

. We have taken steps to ensure the accuracy of this version, but it is not the official version.

4 (2) the reasonably available control me asures/reasonably available control technology demonstration; (3) the reasonable further progress demonstration; (4) the demonstration that attainment by the Moderate area attainment date of December 31, 2015 is impracticable; (5) the District’s commitment s to adopt and implement specific rules and measures on a specific schedule; and (6) the general conformity budgets for NO x and VOC for years 2013

- 2030 in the Plan. 1
T he EPA also proposed to reclassify the South Coast area, including Indian country within it, as a Serious nonattainment area for the 2006 PM 2.5 NAAQS , based on the EPA’s determination that the area could not practicably attain this standard by the applicable Moderate area attainment date of December 31, 2 015.
On December 22 , 2015 , we finalized our proposal to reclassify the South Coast area from Moderate to Serious for the 2006 PM 2.5 NAAQS. 2 As a result of that action, California is required to submit , by August 14, 2017, additional SIP revisions to satisfy the statutory requirements that apply to Serious PM 2.5 nonattainment areas, including the requirements of subpart 4 of part D, title I

5 of the Act. The Serious area plan must provide for attainment of the 2006 PM 2.5 NAAQ S in the South Coast area as expeditiously as practicable, but no later than December 31, 2019, in accordance with the requirements of part D of title I of the Act . In our December 22, 2015 final action to reclassify the South Coast area as a Serious PM 2.5 nonattainment area, we summarized and responded to public comments pertaining to the reclassification and its consequences and stated that we would, in a separate rulemaking, respond to comments pertaining to our proposed action on the submitted plan. 3 II. Public Comments and EPA Responses
The EPA provided a 30

on November 19, 2015, we received ten sets of public
comments on our proposal
. Commen t letters were submitted by Earthjustice on behalf of the Center for Biological Diversity, Coalition for Clean Air, Communities for a Better Environment, East Yard Communities for Environmental Justice, and the Sierra Club (“Earthjustice”) ; the San Pedro B ay Ports ( Ports of Los Angeles and Long Beach , or

Earthjustice asserts that the 2012 PM 2.5 Plan fails to meet minimum requirements for Reasonably Available Control Measures (RACM) because some sources covered under South Coast’s NO x Regional Clean Air Incentives Market (RECLAIM) program have n ot installed control technologies that are economically feasible and readily available.

8 December 4, 2015 amendments to the RECLAIM program, 7 Earthjustice argues that the District itself has found that the current cap on NO x RECLAIM emissions is far above the level of emissions that would be generated if cost

effective and readily available technologies were implemented in the South Coast air basin. Earthjustice also argues that the 2 ton per day (tpd) r eduction in the NO x RECLAIM cap (referred to as the NO x “shave” ) included in the 2012 PM 2.5 Plan falls short of what is actually feasible for certain sectors, where “readily available technologies simply have not been installed because of too many credits in the NO x RECLAIM program.” For example, Earthjustice quotes the District’s statements in the “Draft Final Socioeconomic Report For Proposed Amendments to Regulation
XX

– Regional Clean Air Incentive Market (RECLAIM) NO x RECLAIM” (hereafter “RECLAIM Socioeconomic Report”) indicating that the NO x RECLAIM program, as amended in 2005, has allowed numerous refineries to delay installation of selective catalytic reduction (SCR) controls that the

7 On December 4, 2015, the SCAQMD adopted amendments to the RECLAIM program to implement BARCT for NO x emissions from various equipment by establishing RTC reduction targets and RTC adjustment factors for year 2016 and beyond (See SCAQMD Governing Board Resolution 15

- 25, December 4, 2015).This documen t is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on

9 District had identified as best available retrofit control technology (BARCT). 8 Earthjustice acknowledges the EPA’s policies allowing for cap and trade programs to satisfy RACT by ensuring emission reductions equal, in the aggregate, to the reductions expected from direct application o f RACT on individual affected sources but asserts that, in this case, “EPA cannot simply conclude that a 2 tpd shave to the NO x RECLAIM program satisfies RACT because ‘RECLAIM [must] achieve[] reductions of NO x emissions from covered sources that are equiv alent in the aggregate, to the reductions achieved by RACT

- level controls.’” At a minimum, according to Earthjustice, “RACM requires an assessment of the NO x RECLAIM program in light of new information that the NO x RECLAIM program is woefully far from achi eving reductions commensurate with ‘RACT

- level controls.’” Earthjustice concludes that the District can either amend its NO x RECLAIM program to make it equivalent to RACT

- level controls or adopt direct controls to ensure that readily available and
cost
- eff ective pollution control equipment is installed on many sources that have not installed these controls.

8 BARCT is defined as “an emission limitation that is based on the maximum degree of reduction achievable taking into account environment al, energy, and economic impacts by each class or category of source.” California Health & Safety Code Section 40406.This documen t is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on

10 Response 1 : The EPA has reevaluated the RACM /RACT demonstration in the 2012 PM 2.5 Plan in light of the commenter’s arguments and agrees that the Plan do es not adequately address RACM /RACT for certain NO x emission sources covered by the RECLAIM program. The SCAQMD adopted the RECLAIM program in 1993 to reduce emissions from the largest stationary sources of NO x and SO x emissions through a market

- based trad ing program that establishes annually declining NO x and SO x allocations (also called “facility caps”) and allows covered facilities to comply with their facility caps by installing pollution control equipment, changing operations, or purchasing “RECLAIM tr ading credits” (RTCs) from the RECLAIM market. 9 Section 40440 of the California Health and Safety Code requires the District to monitor advances in BARCT and periodically to reassess the overall facility caps to ensure that the facility caps are equivalent, in the aggregate, to BARCT emission levels imposed on affected

sources . Facilities electing to enter RECLAIM are exempted from a number of SCAQMD prohibitory rules that otherwise

- based cap and trade program may satisfy RACT requirement s by ensuring that the level of emission reductions resulting from implementation of the program will be equal, in the aggregate, to those red uctions expected from the direct application of RACT on all affected sources within the nonattainment area. 11 The EPA approved the RECLAIM program into the California SIP in June 1998 based in part on a conclusion that the NO x emission caps in the program s atisfied the RACT requirements of CAA section 182(b)(2) and (f) for covered
NO x emission sources in the aggregate. 12 In 2005 and 2010, the District adopted revisions to the NO x RECLAIM program, which the EPA approved on August 29, 2006 and August 12, 2011, respectively, based in part on conclusions that the revisions continued to satisfy NO x RACT requirements. 13 We refer to the NO x RECLAIM program as approved into the SIP as the “2010 RECLAIM program.”

12 The recent SCAQMD rulemaking documents that Earthjustice cites call into question the efficacy of the 2010 RECLAIM program in ensuring NO x emission reductions equivalent to RACT

- level controls on all affect ed sources . Specifically, according to a November 4, 2015 draft staff report by the SCAQMD entitled “Proposed Amendments to Regulation XX, Regional Clean Air Incentives Market (RECLAIM), NO x RECLAIM” (hereafter “Draft RECLAIM Staff Report”), between 2009 and 2013, the RECLAIM market contained 5

- 8 tons per day (tpd) of “surplus” RTCs that created a dampen ing effect on RTC prices, bringing average RTC prices down to a range of $1,162

- $5,491 per ton compared to the average cost

- effectiveness of control range, which is $8,300

- $13,000 per ton. 14 As a result, according to the District, RECLAIM facilities opt ed to purchase these low cost “surplus” RTCs to reconcile their emissions at the end of the compliance year instead of installing controls to reduce pollution. 15 For example, refineries did not install any SCR control technologies in response to the 2005 NO x RECLAIM amendment even though SCAQMD staff had estimated about 51 SCRs would be installed

13 by 2011. 16 The Draft RECLAIM Staff Report indicates that SCR has been used successfully to control NO x emissions from various refinery operations and is considered a mature, commercially available, and cost

- effective control technique for this source category . 17 The District concluded in the Draft RECLAIM Staff Report that “[r]emoving surplus RTCs is therefore critically important to ensure the effectiveness of the REC LAIM program and meet state law requirements to require the use of BARCT for existing sources.” Likewise, in the RECLAIM Socioeconomic Report, the District stated that many of these unused “excess” RTCs were sold to operating RECLAIM facilities as a result of facility shutdowns and that “[t]hese excess RTCs have been artificially depressing RTC prices and have induced RECLAIM facilities to delay the installation of cost

- effective controls.” 18

16 Id. The RECLAIM Socioeconomic Report further states that despite a 7.7 tpd NO x RTC shave implemented during 2007

- 2011 through the District’s 2005 amendments to RECLAIM, only 4 tpd of actual NO x emission reductions resulted from this shave, most of which were due to facility shut

- downs and not measures taken to reduce actual emissions by facilities in the program. South Coast Air Quality Management District, “Draft Final Socioeconomic Report For Proposed Amendments to Regulation XX

14 The 2012 PM 2.5 Plan cites the 2010 RECLAIM program as the basis f or the District’s RACM /RACT determination for several NO x emission source categories, including cement kilns, boilers and process heaters at petroleum refineries, and other stationary combustion installations (e.g., steam generators and natural gas and/or oil

- fired industrial/commercial/institutional boilers). 19 The Plan also indicates that, for several source categories for which the District identified more stringent NO x controls implemented in other nonattainment areas, 20 the District intended to reduce NO x emissions or conduct further study through “Control Measure CMB

– Further NO x Reductions from RECLAIM,” 21 a measure that commits the District to achieve an additional 2 tpd of NO x emission reductions through a 2 tpd “shave” to the RECLAIM NO x emission caps in 2015 if the South Coast area fails to attain the 2006 PM 2.5 NAAQS by then. 22 The 2012 PM 2.5 Plan does not explain how

16 equivalent to RACT

- level controls for these sources , we are disapproving the RACM /RACT demonstration in the Plan. Our proposal to find that the 2012 PM 2.5 Plan and 2015 Supplement satisfy the requirement for RFP in CA A section 172(c)(2) was based primarily on a conclusion that the Plan “demonstrates that all RACM/RACT are being implemented as expeditiously as practicable and identifies projected emission levels for 2014 that reflect full implementation of the State’s a nd District’s RACM/RACT control strategy for the area.” 24 Our evaluation of whether the RACM/RACT measures would result in emissions reductions consistent with meeting the RFP requirement of the statute was thus dependent upon the approval of the Plan with respect to the RACM/RACT requirement. Because we are now disapproving the
RACM /RACT demonstration in the Plan, we must also find that the Plan does not satisfy the sta tutory requirement for RFP for the 2006 PM 2.5 NAAQS. As a result of our December 22, 2015 final action reclassifying the South Coast area as Serious nonattainment for the 2006 PM 2.5 NAAQS, California is required to submit by August 14, 2017 a Serious Area plan for the South Coast area, including provisions to assure that the best

17 available control measures (BACM) and best available control technology (BACT) for the control of direct PM 2.5 and PM 2.5 precursors shall be implemented no later than 4 years afte r the area is reclassified. 25 We note that, to the extent the State and District intend to rely on the NO x RECLAIM program as part of the BACM demonstration in this new plan, the plan must include documentation sufficient to demonstrate that the NO x RECLAIM program ensures, in the aggregate, NO x emission reductions equivalent to BACT

- level controls for covered facilities. If t he State and District intend to the correct the deficiency in advance of the BACM submission due August 14, 2017, the y may do so by

su bmitting revisions to the NO x RECLAIM program together with documentation sufficient to demonstrate that the revised program ensures, in the aggregate, NO x emission reductions equivalent to RACT

- level controls for covered facilities. Either type of SIP sub mission would, upon EPA approval, cure the deficiency in the Plan’s RACM /RACT demonstration for the 2006 PM 2.5 NAAQS. The Serious area plan for the 2006 PM 2.5 NAAQS in the South Coast area that California is required to submit by August 14, 2017 must also include plan provisions that

18 provide for RFP consistent with the requirements of CAA section 172(c)(2). A Serious area plan that satisfies the statutory RFP requirement for the 2006 PM 2.5 NAAQS in the South Coast would, upon EPA approval, cure the deficien cy in the 2012 PM 2.5 Plan’s RFP provisions. Comment 2 . Earthjustice argues that the RACM demonstration in the Plan impermissibly relies on mobile source measures that are not approved into the SIP and that the EPA continues to attempt to “illegally credit” waiver measures even though these measures had not been proposed for SIP approval by the time of the EPA’s proposed rule on the 2012
PM 2.5 Plan. Earthjustice further asserts that these waiver measures have ne ver been reviewed for compliance with SIP

related requirements, and that the public has no ability to review and offer comment on the EPA’s assessment of how these mobile source measures satisfy the CAA’s RACM requirements. Citing Committee for a Better Ar vin v. EPA , 786 F.3d 1169 (9th Cir. 2015) (hereafter “CBA”), Earthjustice argues that the EPA’s prior approvals of PM 2.5 plans for the South Coast and San Joaquin Valley nonattainment areas were remanded for failure to include the mobile source control mea sures upon which the plans relied and that it is, therefore, premature to conclude that the RACM requirement has been satisfied.This documen t is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on

19 Response 2 . As we explained in our proposed rule, in response to the Ninth Circuit’s decision in CBA , CARB adopted the necessar y waiver measures as revisions to the California SIP and submitted them to the EPA on August 14, 2015. 26 Our proposed rule for this action stated that the EPA intended to propose action on these waiver measures in a separate rulemaking and that, “[o]nce app roved as part of the SIP, the measures will be enforceable by the EPA or private citizens under the CAA.” 27 Our proposed rule also stated that the EPA was “proposing to approve certain elements of the 2012 PM 2.5 Plan and 2015 Supplement in part based on our expectation that these waiver measures will soon become federally enforceable as a result of our approval of the measures as part of the SIP.” 28 On November 12, 2015, the EPA proposed to approve the submitted waiver measures into the California SIP and
pr ovided a 30

- day period for public comment on its proposal. 29 As part of this proposed rule , the EPA evaluated the necessary waiver measures for compliance with SIP

related requirements and proposed to find that they fulfill

RACM /RACT demonstration in the 2012 PM 2.5 Plan remains deficient pending the EPA’s final action to approve the waiver measures on which it relies. Because we are disapproving the RACM /RACT demonstration in the 2012 PM 2.5 Plan on other grounds, however (see Response 1 ), this conclusion does not al ter our action
. Comments Regarding Motor Vehicle Emissions Budgets Comment 3
. Earthjustice asserts that the EPA’s decision to not act on the motor vehicle emissions budgets (MVEBs) in the 2012 PM 2.5 plan is arbitrary and capricious. According to Earthjustice, the revised budgets in the 2012 PM 2.5 Plan (2015 MVEBs) are significantly strengthened compared to the MVEBs for the 1997 PM 2.5 NAAQS that the EPA approved in 2011 (2011 MVEBs), which are “outdated and less protective.” For example, Earthjust ice asserts that the 2015 MVEBs reflect more accurate emissions data as they are based on EMFAC2011 and transportation activity data from the Southern California Association of Governments’ (SCAG’s) adoptedThis documen t is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on

21 2012 Regional Transportation Plan, whereas the 20 11 MVEBs relied on EMFAC2007, the prior transportation plan, and other outdated information. Additionally, Earthjustice claims that the 2011 MVEBs were “not sufficiently stringent because evidence shows the South Coast air basin has not attained the 1997 P M 2.5 standard” and “certainly are not sufficiently strong to meet the 2006 PM 2.5 standard and interim milestones to ensure attainment of this standard.” Earthjustice contends that it is arbitrary to allow the 2011 MVEBs to remain in place for the next
tra nsportation plan when revised budgets are available, especially in the South Coast where transportation emissions account for such a large amount of the PM 2.5 and ozone pollution problems. Earthjustice further argues that it is critically important to have these revised budgets in place given the imminent 2016 transportation plan being prepared by SCAG. Response 3 . We disagree with these comments. As we explained in our proposed rule, the 2015 Supplement, which CARB submitted in March 2015, revised the attainment demonstration in the 2012 PM 2.5 Plan to identify December 31, 2015 as the applicable attainment date and included revised motor vehicle emission budgets (MVEBs) forThis documen t is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on

22 2015 for direct PM 2.5 , NO x , and VOC. 30 In July 2015, however, the District submit ted preliminary air quality monitoring data that indicated that attainment of the 2006 PM 2.5 NAAQS by the Moderate area attainment date (December 31, 2015) was impracticable. 31 Based on these air quality data, the District requested that the EPA treat the 2 012 PM 2.5 Plan and 2015 Supplement as a demonstration that attainment by the Moderate area attainment date is impracticable and that the EPA reclassify the South Coast air basin as a Serious nonattainment area for the 2006 PM 2.5 NAAQS. 32 We therefore evalua ted the 2012 PM 2.5 Plan and 2015 Supplement as a demonstration of impracticability under CAA section 189(a)(1)(B)(ii) and proposed to approve it based on a conclusion that it satisfies the statutory requirements for such demonstrations. Section 93.118(e)(4 ) of the conformity rule states that “EPA will not find a motor vehicle emissions budget in a submitted control strategy implementation plan revision or maintenance plan to be adequate for transportation conformity purposes” unless specific criteria are

sa tisfied, including the requirement in subsection (iv)

23 that “the motor vehicle emissions budget(s), when considered together with all other emissions sources, is consistent with applicable requirements for reasonable further progress, attainment, or mainten ance (whichever is relevant to the given implementation plan submission).” The 2012 PM 2.5 Plan and 2015 Supplement contain MVEBs only for the 2015 attainment year. 33 The Plan does not demonstrate timely attainment and does not contain an approvable RFP demonstration or any RFP budgets. Because the Plan does not contain a control strategy that satisfies the requirements for RFP, attainment, or maintenance, the EPA cann ot find that the MVEBs included with this plan meet the specific requirement in 40 CFR section 93.118(e)(4)(iv) that “the motor vehicle emissions budget(s), when considered together with all other emissions sources, is consistent with applicable requiremen ts for reasonable further progress, attainment, or maintenance

- approved or adequate MVEBs for the 2006 PM 2.5 NAAQS but does have approved MVEBs in an approved SIP for the 1997 PM 2.5 NAAQS, which is another NAAQS of the same pollutant ( PM 2.5 ). Therefore, until the EPA finds that a
MV EB in a submitted control strategy SIP for the 2006 PM 2.5 NAAQS is adequate for transportation conformity purposes, conformity determinations for the 2006 PM 2.5 NAAQS in the South Coast area must satisfy the budget test as required by section 93.118 using the approved MVEBs for the 1997
PM 2.5 NAAQS. Upon the effective date of the EPA’s finding that a MVEB in a submitted control strategy SIP for the 2006 PM 2.5 NAAQS is adequate for transportation conformity purposes, or upon the publication date of the EPA’s approval of such a budget in the Federal Register , conformity determinations for the 2006 PM 2.5 NAAQS in the South Coast area will have to satisfy the budget test in section 93.118 using such approved MVEBs for the 2006 PM 2.5 NAAQS. 34

25 In sum, because the 2 012 PM 2.5 Plan and 2015 Supplement do not contain a control strategy that satisfies the requirements for RFP, attainment, or maintenance, the EPA cannot find that the MVEBs included in the Plan are adequate for conformity purposes and cannot approve these budgets. Accordingly, we are taking no action on the 2015 MVEBs included in the Plan . B ecause the South Coast air basin has no SIP

- approved or adequate MVEBs for the 2006
PM 2.5 NAAQS but does have approved MVEBs in an approved SIP for the 1997 PM 2.5 NAAQS, conformi ty determinations for the 2006 PM 2.5 NAAQS in the South Coast area must satisfy the budget test as required by section 93.118 using the approved MVEBs for the 1997 PM 2.5 NAAQS, until the EPA finds that a MVEB in a submitted control strategy SIP for the 200 6 PM 2.5 NAAQS is adequate for transportation conformity purposes in the South Coast air basin.

26 spot transportation conformity analyses across California. 36 Although CARB has until A ugust 14, 2017 to submit a Serious area plan for the 2006 PM 2.5 NAAQS in the South Coast area, 37 we encourage the State to submit this plan and revised MVEBs using EMFAC2014 before that date to ensure that conformity analyses for the 2006 PM 2.5 NAAQS in the South Coast air basin use the latest emission estimation model available consistent with the requirements of 40 CFR 93.111. Other Comments Comment 4. We received three comments from Harvey Eder on behalf of the Public Solar Power Coalition (PSPC). The commenter states his intent to incorporate by reference material submitted to the EPA on behalf of PSPC in several prior EPA rulemaking actions, EPA and presidential statements concerning solar power, and several unspecified magazine and new s paper articles, but does not identify the purpose for which he intends to incorporate these materials by reference. The commenter suggests that EPA Control Techniques Guidelines (CTGs) and Alternative Control Techniques documents (ACTs) “do not exist” and that these would need to be developed “before[] solar can be used as

- fine particulates. Additionally, the commenter asserts that it is reasonable to include solar power as a NO x control measure, and that the South Coast area needs a “100% ITSC Immediate Total Solar Conversion Plan by 2020

To the extent the commenter intended to encourage additional evaluation of potential solar power installations that may red uce pollution in the South Coast area, the EPA encourages the commenter to participate in the regulatory processes carried out by the SCAQMD, CARB, and other State/local agencies involved in the development of air quality management plans in the South Coas t. The EPA finds no basis in these comments to change its proposed action on the Plan. With respect to the commenter’s request to incorporate material by reference, the EPA generally will not consider comments or comment contents located outside of the pr imary submission (i.e., on the web, cloud, or other file

Final Action The EPA is taking final action to approve and disapprove SIP revisions submitted by the State of California to address attainment of the 2006 PM 2.5 NAAQS in the South Coast PM 2.5 nonattainment area . These SIP revisions are the 2012 PM 2.5 Plan, submitted February 13 , 2013, and the 2015 Supplement, submitted March 4, 2015
. Under CAA section 110(k)(3), the EPA is approving the following elements of the 2012 PM 2.5 Plan and 2015 Supplement: 1. the 2008 base year emissions invent o ries as meeting the requirements of CAA section 172(c)(3); 2 . the demonstration that attainment by the Moderate area attainment date of December 31, 2015 is impracticable as meeting the requirements of CAA section 189(a)(1)(B)(ii); 3 .
