ACTION: Final rule.
SUMMARY: The Environmental Protection Agency (EPA) is taking final action to reclassify the Los Angeles

- South Coast Air Basin (S outh Coast ) Moderate PM 2.5 nonattainment area, including areas of Indian country within it, as a Serious nonattainment area for the 2006 PM 2.5 national ambient air quality standards (NAAQS), based on the EPA's determination that the area cannot practicably attain th ese NAAQS by the applicable attainment date of December 31, 2015. As a consequence of this reclassification, California must submit , no later than 18 months from the effective date of this reclassification, nonattainment new source review (NNSR) program revisions and a Se rious area attainment plan including a demonstration that the plan provides for attainment of the 2006 24

V. Statutory and Executive Order Reviews I. Proposed Action
On October 20 , 2015 (80 FR 63640) , the EPA proposed to approve portions of California’s Moderate area plan to address the 2006 primary and secondary 24

- hour PM 2.5 NAAQS in the S outh
Coast and to reclassify the S outh Coast nonattainment area, including areas of Indian country within it, from Moderate to Serious nonattainment for the se standard s , based on the EPA's determination that the area cannot practicably attain the se NAAQS by the appl icable attainment date of December 31, 2015. 1 Under section 188(b)(1) of the CAA, prior to an area's attainment date, the EPA has discretionary authority to reclassify as a Serious nonattainment area “any area that the

4 Administrator determines cannot pract icably attain” the PM 2.5 NAAQS by the Moderate area attainment date. 2 As part of our proposed action, we reviewed recent PM 2.5 monitoring data for the South Coast available in EPA’s Air Quality System (AQS) database. These data show that 24

- hour PM 2.5 leve ls in the South Coast continue to be above 35 μg/m 3 , the level of the 2006 PM 2.5 standards, and the recent trends in the South Coast area’s 24

- hour PM 2.5 levels are not consistent with a projection of attainment by the end of 2015. 3

In the proposed rule, we explained that under section 188(c)(2) of the Act, the attainment date for a Serious area “shall be as expeditiously as practicable but no later than the end of the tenth calendar year beginning after the area’s designation as nonattainm ent... . ” The S outh Coast was designated

2 Section 188(b)(1) of the Act is a general expression of delegated rulemaking authority. See “State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990,” 57 FR 13498 (April 16, 1992) (hereafter “General Preamble”) at 135 37, n. 15. Although subparagraphs (A) and (B) of section 188(b)(1) contain specific timeframes for EPA to reclassify any areas that it determines cannot practicably attain the PM standards by the applicable attainment date , these subparagraphs do not restr ict the general authority to reclassify an area, as appropriate, at any time before the attainment date but simply specify that, at a minimum, the EPA's authority must be exercised at certain times. See id. 3 The PM 2.5 monitoring data that EPA reviewed indicate that 24

- hour PM 2.5 design value s are at 38 ug/m3 in the South Coast , above the level of the 2006 PM 2.5 NAAQS (35 ug/m3) . EPA also calculated “maximum allowed” 2015 98 th percentile concentrations that would enable the area to attain the 2006 24

- hou r PM 2.5 NAAQS by the end of 2015 and found that even conservative estimates of the 98 th percentile concentration in 2015 at two monitoring sites

– Rubidoux and Mira Loma

- Van Buren

– were greater than the “maximum allowed” concentration. See 80 FR 63640, 63 653 (October 20, 2015) and Memorandum dated August 21, 2015, Michael Flagg, US EPA Region 9, Air Quality Analysis Office.This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

5 nonattainment for the 2006 PM 2.5 NAAQS effective December 14, 2009. 4 Therefore, as a result of our reclassification of the
S outh Coast area as a Serious nonattainment area, the attainment date under section 188(c)(2) o f the Act for the 2006 PM 2.5 NAAQS in this area is as expeditiously as practicable but no later than December 31, 2019
.

O ur proposed rule also identified the Serious area attainment plan elements that California would, upon reclassification, have to subm it to satisfy the statutory requirements that apply to Serious areas, including the requirements of subpart 4 of part D, title I of the Act. 5 The EPA explained that under section 189(b)(2) of the Act, the State must submit the required provisions to implement best available control measures (BACM), including best available control technology (BACT), no later than 18 months after reclassification and must submit the required attainment demonstration no later than 4 years after reclassification. We noted, however, that section 189(b)(2) establishes outer bounds on the SIP submission deadlines and does not preclude the EPA's establishment of earlier dea dlines as necessary or appropriate to assure consistency among the required submissions and to

6 implement the statutory requirements in a timely manner to ensure expeditious attainment of the NAAQS
. 6 Because an up
- to
date emissions inventory serves as the f oundation for a state's BACM and BACT determinations, the EPA proposed to require the State to submit the emissions inventory required under CAA section 172(c)(3) within 18 months after the effective date of final reclassification. Similarly, because an ef fective evaluation of BACM and BACT requires evaluation of the precursor pollutants that must be controlled to provide for expeditious attainment, the EPA proposed to require the State to submit any optional precursor insignificance demonstrations by this same date. The EPA proposed to require the State to submit the attainment demonstration required under section 189(b)(1)(A) and all other attainment

- related plan elements for the South Coast

area no later than three years after the effective date of final reclassification or by December 31, 2018, whichever is earlier.
With respect to the nonattainment new source review (NNSR) program revisions to establish appropriate “major stationary source” thresholds for direct PM 2.5 and PM 2.5 precursors in accordance w ith CAA section 189(b)(3), the EPA proposed to require the State to submit these NNSR SIP revisions for the

. II. S ummary of Final Action Today we are finalizing only our proposal to reclassify the
S outh Coast area as a Serious nonattainment area for the 2006
PM 2.5 NAAQS . We are not taking final action at this time on our proposal to approve elements of California’s Moderate area plan for the 2006 PM 2.5 NAAQS in th e S outh Coast and will complete that action at a later time
. A s a consequence of our reclassification of the S outh Coast

area as Serious nonattainment for the 2006 PM 2.5 NAAQS, California is required to submit additional SIP revisions to satisfy the statutory requirements that apply to Serious areas, including the requirements of subpart 4 of part D, title I of the Act. For the reasons provided in Section II I of this
prea mble , the EPA is requiring the State to adopt and submit all required components of the Serious Area plan for the South Coast

area , including nonattainment new source review ( NNSR ) SIP revisions to address the statutory requirements fo r Serious areas under subpart 4, no later than 18 months after the effective date of this reclassification.
T he attainment date under section 188(c)(2) of the Act for the 2006 PM 2.5 standard s in this area is as expeditiously as practicable but no later than December 31, 2019.This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

8 I II. Public Comments and EPA Responses
Because we are finalizing only our proposal to reclassify the S outh Coast area as Serious nonattainment for the 2006 PM 2.5 NAAQS , we are responding only to comments pertaining to the reclassification and its consequences. The EPA received several comment letters on our proposed actions, only one of which contains comments relevant to the reclassification. Th e comment letter was submitted by Earthjustice o n behalf of the Center for Biological Diversity, Coalition for Clean Air, Communities for a Better Environment, East Yard Communities for Environmental Justice, and Sierra Club (“Earthjustice”) on November 19 , 2015, prior to the close of the comment period on our proposal. 7 We summarize and respond to the relevant comments below. In a separate rulemaking, we will take final action on California’s submitted Moderate area plan for the 2006 PM 2.5 NAAQS in the
S outh Coast and will respond to comments pertaining to our proposed action on the submitted plan at that time.
Comment 1 : Earthjustice argues that section 188(b)(1) establishes specific outside deadlines for the EPA’s reclassification of appropriate areas as Serious nonattainment and “does not provide general authority to reclassify areas

9 anytime EPA chooses before the attainment deadline.” Citing CAA section 188(b)(1)(B), Earthjustice asserts that the EPA’s discretionary authority to reclassify a Moderate area as a Serious area before the attainment deadline is available only within 18 months after the required date for the submission of a Moderate area SIP, which in turn is due within 18 months after the area’s designation as nonattainment. Because the South Coast

a rea was designated nonattainment for the 2006 PM2.5 NAAQS on December 14, 2009, according to Earthjustice, the Moderate area SIP for the area was due June 14, 2011, and the “deadline for approving a voluntary reclassification request” was therefore Decembe r 14, 2012. Thus, Earthjustice argues, “EPA no longer has authority under the statute to use section 188(b)(1) to voluntarily reclassify the South Coast basin and provide four years for submission of a serious area plan.”
In support of these arguments, Ea rthjustice quotes from EPA’s 1992 General Preamble, 8 which states that “[f]or areas designated nonattainment after enactment of the 1990 [Clean Air Act Amendments], EPA must reclassify appropriate areas as serious within 18 months of the required submittal date for the moderate area SIP” and that, read together with the statutory

10 requirement to submit such SIPs within 18 months after nonattainment designations, the Act requires EPA to reclassify these areas as serious within three years of the nonattainment designation.

Response 1 : We dis agree with the commenter ’s argument that the EPA’s discretionary authority in section 188(b)(1) is limited to the timeframes set forth in sections 188(b)(1)(A) and (B)
. The EPA is reclassifying the South Coast area as Serious nonattainment pursuant to the general authority in CAA section 188(b)(1), 9 not pursuant to section 188(b)(1)(B). As explained in the 1992 General Preamble, “[u]nder the plain meaning of the terms of section 188(b)(1), EPA has general discretion to reclassify at any time before the applicable attainment date any area EPA determines cannot practicably attain the standards by such date” (emphases added). 10 With respect to the dates specified in subsections (A) and (B) of section 188(b)(1), the EPA speci fically explained in the General Preamble that “[t]hese subparagraphs do not restrict the general authority [in section 188(b)(1)] but simply specify that, at a minimum, it must be

9 Unlike the "voluntary reclassification" provision in CAA section 181(b)(3), which requires EPA to grant the request of any state to reclassify an ozone nona ttainment area in that state to a higher classification, the "discretionary reclassification" provision in CAA section 188(b)(1) grants EPA general authority to reclassify areas in accordance with the statutory criteria therein, independent of state reques ts. 10 General Preamble, 57 FR 13498, 13537 at n. 15 (April 16, 1992).This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

11 exercised at certain times.” 11 This interpretation of section 188(b)(1) as allowing the EPA to reclassify moderate areas as serious “at any time EPA determines that an area cannot practicably attain the standards by the applicable attainment date” facilitates the statutory objective of attaining the PM

- 10 standards

– e.g., by ensuring that additional control measures such as BACM are implemented sooner and by expediting the application of more stringent new source review requirements. 12 The EPA reiterated this interpretation of section 1 88(b)(1) in the 1994 PM

- 10 Addendum 13 and in several discretionary reclassification actions subsequent to the 1990 CAA Amendments. 14
Specifically, with respect to areas designated nonattainment by operation of law upon enactment of the 1990 CAA Amendments ( i.e., "initial" PM

- 10 nonattainment areas), the EPA's longstanding interpretation of section 188(b)(1)(A) has been that “the amended Act specifies certain dates by which EPA

- 10 NAAQS by December 31, 1994,” 16 and provided examples of the circumstances that may warrant such discretionary reclassification at a later date

– i.e., after the December 31, 1991 date specified in section 188(b)(1)(A). 17 In the PM

- 10 Addendum, the EPA stated that "[s]ection 188(b)(1)(A) provides an accelerated schedule by which EPA is to reclassify appropriate initial PM

13 reclassify initial PM

- 10 areas at later points in time before the attainment date. 18
Likewise, the EPA has long interpreted section 188(b)(1)(B) as establishing a "timeframe within which EPA is to reclassify appropriate areas designated nonattainment for PM

- 10 subsequent to enactment of the 1990 Amendments" but not as a limitation on EPA's general autho rity to reclassify such areas at any time before the applicable attainment date. 19 In the PM

- 10 Addendum, the EPA reiterated its view that the directive in section 188(b)(1)(B) “does not restrict EPA’s general authority , but simply specifies that it is to b e exercised, as appropriate, in accordance with certain dates.” 20 The EPA recently finalized a discretionary reclassification action for a PM 2.5 nonattainment shortly before the applicable attainment date, consistent with this interpretation of CAA section 188(b)(1). 21

- 10 Addendum that reiterates the Agency’s interpretation of section 188(b)(1)(B) specifically. Moreover, both the statutory text in CAA section 188(b)(1)(B) and the interpretive language in the General Preamble that the commenter quotes explicitly state that the EPA’s obligation under CAA section 188(b)(1)(B) is to reclassify “appropriate” areas within 18

mo nths after the required date for the State’s submission of a SIP for the Moderate Area
. 22 Congress granted the EPA broad discretion to identify the areas that are "appropriate" for such reclassification 23 and to reclassify additional areas after the timeframes specified in subsections (A) or (B) . T hus, t he fact that the EPA did not find the South Coast area “appropriate” for discretionary reclassification within the timeframe specified in section 188(b)(1)(B) does not preclude the EPA ’s discretionary reclassification of the area at a later date, based on a

22 See CAA section 188(b)(1)(B) (requiring, for areas designated nonattainment after enactment of the 1990 CAA Amendmen ts, that the Administrator “reclassify appropriate areas” within 18 months after the required date for the State’s submission of a SIP for the Moderate Area). 23 As EPA explained in its 1993 reclassification of “appropriate” initial PM
10 nonattainment are as from M oderate to S erious under section 188(b)(1)(A), the Act does not specify what information EPA must consider in exercising the authority delegated to it by section 188(b)(1) and thus grants EPA broad discretion to consider any relevant information, including information in SIP submittals . 58 FR 3334, 3336 at n. 7 (Jan. 8, 1993).This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

15 determination that the area cannot practicably attain the PM 2.5 NAAQS by the applicable attainment date.
Furthermore, under the commenter’s interpretation of section 188(b)(1)(B), the EPA would have no authority to reclassify a Moderate area to Serious at any time between the date 3 years after designation ( 18 months after the required date for the State’s submission of a Moderate Area SIP) a nd the applicable attainment date, which under section 188(c)(1) may be as late as the end of the sixth calendar year after the area’s designation as nonattainment. Thus, for a period of up to 3 years, the EPA would be unable to reclassify such an area to Serious in order to require the State to adopt BACM measures and other Serious Area plan elements, even if information before the Agency indicated the area could not attain the NAAQS by the moderate area attainment date. Such a reading of section 188(b)(1) would frustrate the Congressional intent to ensure that areas that cannot attain the NAAQS in a timely manner adopt the best available controls and develop revised plans to provide for expeditious attainment. EPA’s interpretation of section 188(b)(1) as a general grant of discretionary reclassification authority is reasonable in light of the overarching requirement in subpart 4 to ensure attainment of the NAAQS as expeditiously as practicable.This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

16 In sum, we disagree with the commenter’s contention that the EP A’s authority to reclassify a Moderate area as a Serious area under CAA section 188(b)(1) is available only within 18 months after the due date for the State’s Moderate Area SIP . As the EPA explained in the General Preamble, in the PM

- 10 Addendum, and in several action s reclassifying PM

- 10 and PM 2.5 nonattainment areas as S erious areas under CAA section 188(b)(1), the EPA has consistently interpreted section 188(b)(1) as a general expression of delegated rulemaking authority that authorizes the Agency to r eclassify an y Moderate

area as a Serious area at any time before the applicable attainment date , based on a determination that the area cannot practicably attain the relevant NAAQS by that date.

Comment 2 : Earthjustice argues that even if the EPA had discretion to reclassify the South Coast area under section 188(b)(1), a December 31, 2018 deadline for the Serious Area plan is “arbitrary in the extreme” and inconsistent with other deadlines that EPA has proposed to establish. First, Earthjustice assert s that the EPA’s proposed deadline ignores the statutory requirement to demonstrate attainment by the most expeditious attainment date and allows the District to “assume the maximum amount of time without any such demonstration.” Second, Earthjustice claim s that the EPA’s proposed approachThis document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

17 “undermines the strict schedule established in subpart 4” and cannot be reconciled with either December 14, 2016 or December 31, 2017, the statutory SIP submission deadlines that allegedly apply following voluntary reclas sification or failure to attain, respectively. Third, Earthjustice argues that there is no basis for claiming that the District needs 3 years to prepare a serious area plan, in light of the 18

- month deadlines in sections 189(a)(2)(B) and 189(b)(2) for mode rate area plans and serious area plans, respectively, and the 18

- month timeframe allowed in section 179(a) for states to cure disapprovals or failures to submit. Finally, Earthjustice argues that the proposed deadline is internally inconsistent with other components of the EPA’s proposal, including the requirements for RFP and quantitative milestones, and undermines the EPA’s and the public’s ability to ensure timely compliance with these requirements.
Response 2 : We disagree with the commenter’s argument t hat the outside deadline for submitting a Serious area attainment plan for the 2006 PM 2.5 NAAQS following discretionary reclassification is December 14, 2016. This argument is premised on the commenter’s assertion that the EPA’s discretionary authority to reclassify the area under CAA section 188(b)(1) was available only within three years after the area’s designation as nonattainment ( i.e., until December 14, 2012), and that CAAThis document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

18 section 189(b)(2) established a deadline 4 years after this date (December 14, 2016 ) for the State to submit its Serious area attainment plan. T he EPA did not reclassify the South Coast area by December 14, 2012 and was not obligated to do so under CAA section 188(b)(1), as explained above in Response 1
. Thus, section 189(b)(2) does not establish a December 14, 2016 outer deadline for submission of the Serious area attainment plan. Upon further consideration and in light of the specific circumstances in the South Coast PM 2.5 nonattainment area, however, the EPA is exercising its discretion to establish a deadline of 18 months from the effective date of this final reclassification action for the State to submit all required components of the Serious Area plan for the 2006 PM 2.5 NAAQS in the South Coast ai r basin. An 18

- month deadline for submission of these SIP elements is appropriate in this instance because it both enables the EPA to evaluate the required attainment plan well before the outermost attainment date applicable to the area under CAA section 1 88(c)(2) and enables the State to develop its strategy for attaining the 2006 PM 2.5 NAAQS in conjunction with its development of a plan to provide for attainment of the 2012 primary annual PM 2.5 NAAQS in this same area, which is due October 15, 2016. 24 Although the State's obligations with respect to

19 implementation of a Moderate area plan for the 2012 PM 2.5 NAAQS are separate and distinct from its obligations with respect to implementation of a Serious area plan for the 2006 PM 2.5 NAAQS, it is reasonable in this instance to require the State to develop its control strategies for both PM 2.5 NAAQS in the South Coast area in a similar timeframe, considering the benefits of streamlining these planning processes to the extent possible. In addition, as the c ommenter notes, an 18

- month deadline for submission of the Serious a rea plan is consistent with both the timeframe for initial Moderate a rea plan submissions upon designation of an area as nonattainment and the timeframe for Serious a rea plan submission s following an EPA determination of failure to attain and reclassification by operation of law under
CAA section 188(b)(2). 25 It is reasonable for the EPA to exercise its discretion to establish a similar SIP submission deadline in this instance, given the p roximity of th is action to th e Moderate area attainment date (December 31, 2015) and the likelihood that , should the attainment date pass, the EPA would have to determine under section 188(b)(2) that the South Coast area failed to attain the PM 2.5 NAAQS by that date. Although CAA section 189(b)(2) generally provides for up to 4 years after a

California is required to adopt and submit a plan to provide for attainment of these NAAQS within 18 months after the nonattainment designation, i.e., by October 15, 2016. 25 CAA 189(a)(2)(B) and 189(b)(2)

20 discretionary reclassification for the State to submit the required attainment demonstration, we find it appropriate in this case to establish an earlier SIP submission deadline to assure timely implementation of the statutory requirements. 26 Furthermore, t he 18

- month SIP submission deadline that we are finalizing in this action requires California to submit its Serious Area plan for the South Coast area before the statutory SIP submission deadline that would apply upon reclassification by operation of law under section 188(b)(2). 27
I V . Final Action A. Reclassification as Serious Nonattainment and Applicable Attainment Date

In accordance with section 188(b)(1) of th e Act, the EPA is taking final action to reclassify the S outh Coast area from Moderate to Serious nonattainment for the 2006 24

- hour PM 2.5 standard s of 35 μg/m 3 , based on the EPA's determination that the

26 Section 189(b)(2) establishes outer bounds on the SIP submission deadlines and does not preclude the EPA’s establishment of earlier deadlines as necessary or appropriate to assure consistency among the required submissions and to implement the statutory requirements , including the requirement that attainment be as expeditious as practicable
. 27 Under CAA section 188(b)(2), the EPA must determine within 6 months after the applicable attainment date whether the area a ttained the NAAQS by that date. If the EPA determines that a Moderate Area is not in attainment after the applicable attainment date, the area is reclassified by operation of law as a Serious Area, and the Serious Area attainment plan is due within 18 months after such reclassification. CAA sections 188(b)(2) and 189(b)(2).This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

21 South Coast area cannot practicably attain th ese standard s by the applicable attainment date of December 31, 2015.
Under section 188(c)(2) of the Act, the attainment date for a Serious area “shall be as expeditiously as practicable but no later than the end of the tenth calendar year beginning after the area's designation as nonattainment. . . .” The South Coast

area w as designated nonattainment for the 2006 PM 2.5 standards effective December 14, 2009. 28 Therefore, as a result of our reclassification of the South Coast area as a Serious nonattainment area, the attainment date under section 188(c)(2) of the Act for the 20 06 PM 2.5 standard s in this area is as expeditiously as practicable but no later than December 31, 2019.
B. Reclassification of Reservation Areas of Indian Country

Seven Indian tribes are located within the boundaries of the South Coast PM 2.5 nonattainment area: t he Cahuilla Band of Indians, the Morongo Band of Cahuilla Mission Indians, the Pechanga Band of Luiseno Mission Indians of the Pechanga Reservation, the Ramona Band of Cahuilla, the San Manuel Band of Serrano Mission Indians of the San Manuel Reserv ation, the Santa

22 Rosa Band of Cahuilla Indians, and the Soboba Band of Luiseno Indians.

We have considered the relevance of our final action to reclassify the S outh Coast nonattainment area as Serious nonattainment for the 2006 PM 2.5 standards to each trib e located within the S outh Coast area. As discussed in more detail in our proposed rule, we believe that the same facts and circumstances that support the reclassification for the non

- Indian country lands also support reclassification for reservation areas of Indian country 29 and any other areas of Indian country where the EPA or a tribe has demonstrated that the tribe has jurisdiction located within the S outh Coast nonattainment area. 30 In this final action, the EPA is therefore exercising our authority under CAA section 188(b)(1) to reclassify reservation areas of Indian country and any other areas of Indian country where the EPA or a tribe has demonstrated that the tribe has jurisdictio n geographically located in the S outh Coast nonattainment area.

29 “Indian country” as defined at 18 U.S.C. 1151 refers to: “(a) all land within the limits of any Indian reservation under the jurisdiction of the United States Government, notwithstanding the issuance of any patent, and, including rights

- of

- way running through the reservation, (b) all de pendent Indian communities within the borders of the United States whether within the original or subsequently acquired territory thereof, and whether within or without the limits of a state, and (c) all Indian allotments, the Indian titles to which have n ot been extinguished, including rights

- of

- way running through the same.”

30 See 80 FR 63640 , at 63659, 63660 ( October 20 , 2015).This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

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

23 Section 188(b)(1) broadly authorizes the EPA to reclassify a nonattainment area

— - including any such area of Indian country located within such area

— - that the EPA determines cannot practicably attain the relevant standard by the applicable attainment date.
In light of the considerations outlined above and in our proposed rulemaking that support retention of a uniformly

classified PM 2.5 nonattainment area, and our finding that it is impracticable for the area to attain by the applicable attainment date, we are finalizing our reclassification of the reservation areas of Indian country and any other areas of Indian country where the EPA or a tribe has demonstrated that the tribe has jurisdiction wit hin the South Coast nonattainment area to Serious for the 2006 PM 2.5 NAAQS .

The effect of reclassification would be to lower the applicable “major stationary source” emissions thresholds for direct PM 2.5 and PM 2.5 precursors for purposes of the NNSR program and the Title V operating permit program (CAA sections 189(b)(3) and 501(2)(B)), thus subjecting more new or modified stationary sources to these requirements. The reclassification may also lower the de minimis threshold under the CAA's General Conformity requirements (40 CFR part 93, subpart B) from 100 tpy to 70 tpy. Under the General Conformity requirements (40 CFRThis document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

24 part 93, subpart B), f ederal agencies bear the responsibility of determining conformity of actio ns in nonattainment and maintenance areas that require f ederal permits, approvals, or funding. Such permits, approvals or funding by f ederal agencies for projects in these areas of Indian country may be more difficult to obtain because of the lower de mini mis thresholds.
Given the potential implications of the reclassification, the EPA contacted tribal officials to invite government

- to
government consultation on this rulemaking effort. 31 The EPA did not receive requests for consultation or comments on our
pr oposed rule from any tribe. We continue to invite Indian tribes in the S outh Coast to contact the EPA with any questions about the effects of this reclassification on tribal interests and air quality. We note that although eligible tribes may opt to seek E PA approval of relevant tribal programs under the CAA, none of the affected tribes will be required to submit an implementation plan to address this reclassification.

C. PM 2.5 Serious Area SIP Requirements
As a consequence of our reclassification of the S o uth Coast area as a Serious nonattainment area for the 2006 PM 2.5 NAAQS,

31 As discussed in more detail in our proposed rule, the EPA sent letters to tribal officials inviting government

25 California is required to submit additional SIP revisions to satisfy the statutory requirements that apply to Serious areas, including the requirements of subpart 4 of part D, title I of the Act.

The Serious area SIP elements that California must submit within 18 months of reclassification are as follows:
1. Provisions to assure that BACM, including BACT for stationary sources, for the control of direct PM 2.5 and PM 2.5 precursors shall be implemented no later than 4 years after the area is reclassified (CAA section 189(b)(1)(B));
2. A demonstration (including air quality modeling) that the plan provides for attainment as expeditiously as practicable but no later than December 31, 2019, or where the State is seeking an extension of the attainment date under section 188(e), a demonstration that attainment by December 31, 2019 is impracticable and that the plan provides for attainment by the most expeditious alternative date practicable (CA A sections 188(c)(2) and 189(b)(1)(A));
3. Plan provisions that require reasonable further progress (RFP) (CAA section 172(c)(2));This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

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

26 4. Quantitative milestones which are to be achieved every 3 years until the area is redesignated attainment and which demonst rate RFP toward attainment by the applicable date (CAA section 189(c));
5. Provisions to assure that control requirements applicable to major stationary sources of PM 2.5 also apply to major stationary sources of PM 2.5 precursors, except where the State dem onstrates to the EPA's satisfaction that such sources do not contribute significantly to PM 2.5 levels that exceed the standard in the area (CAA section 189(e));
6. A comprehensive, accurate, current inventory of actual emissions from all sources of direct PM 2.5 and all PM 2.5 precursors in the area (CAA section 172(c)(3));
7. Contingency measures to be implemented if the area fails to meet RFP or to attain by the applicable attainment date (CAA section 172(c)(9)); and
8. A revision to the NNSR program to est ablish appropriate “major stationary source” 32 thresholds for direct PM 2.5 and PM 2.5 precursors (CAA section 189(b)(3)).

32 For any Serious area, the terms “major source” and “major stationary source” include any stationary source that emits or has the potential to emit at least 70 tons per year of PM 10 (CAA section 189( b)(3)).This document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

27 Section 189(b)(2) states, in relevant part, that the State must submit the required BACM provisions “no later than 18 months after reclassification of the area as a Serious Area” and must submit the required attainment demonstration “no later than 4 years after reclassification of the area to Serious.” As stated above in section I, the EPA proposed to require the State to submit certa in elements of the Serious area plan within 18 months of reclassification and other elements within 3 years of reclassification . For the reasons provided in Section II I of this preamble (Public Comments and EPA Responses), the EPA is requiring the State to adopt and submit all required components of the Serious Area plan for the South Coast area , including NNSR SIP revisions to address the statutory requirements fo r Serious areas under subpart 4, no later than 18 months after the effective date of this reclassification.

28 This action is exempt from review by the Office of Management and Budget (OMB) because it relates to a designation of an area for air quality purposes and will reclassify the
Sout h Coast from its current air quality designation of Moderate nonattainment to Serious nonattainment for the 2006 PM 2.5 NAAQS.
B. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under the PRA. This action does not contain any information collection activities.
C. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. This action will not impose any requirements on small entities. The final rule requires the state to adopt and submit SIP revisions to satisfy the statutory requirements that apply to Serious areas, and would not itself directly regulate any small entities ( see section III.C of this final rule).

D. Unfunded Mandates Reform Act (UMRA)
This action does not contain any unfunded mandate of $100 million or more and does not significantly or uniquely affect small governments, as described in UMRA (2 U.S.C. 1531

29 This action itself imposes no enforcea ble duty on any state, local, or tribal governments, or the private sector. The final action reclassifies the South Coast nonattainment area as Serious nonattainment for the 2006 PM 2.5 NAAQS, which triggers existing statutory duties for the state to submit SIP revisions. Such a reclassification in and of itself does not impose any federal intergovernmental mandate. The final action does not require any tribes to submit implementation plans.

E. Executive Order 13132: Federalism

This action does not have fede ralism implications.
F. Executive Order 13175, Consultation and Coordination With Indian Tribal Governments
This action may have tribal implications. However, it will neither impose substantial direct compliance costs on federally recognized tribal governm ents, nor preempt tribal law. Seven Indian tribes are located within the boundaries of the South
Coast nonattainment area for the 2006 PM 2.5 NAAQS: t he Cahuilla Band of Indians, the Morongo Band of Cahuilla Mission Indians, the Pechanga Band of Luiseno Mis sion Indians of the Pechanga Reservation, the Ramona Band of Cahuilla, the San Manuel Band of Serrano Mission Indians of the San Manuel Reservation, the Santa Rosa Band of Cahuilla Indians, and the Soboba Band of LuisenoThis document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

30 Indians. We note that only one of t he tribes located in the South Coast nonattainment area (the Pechanga Band of Luiseno Mission Indians of the Pechanga Reservation) ha s requested eligibility to administer programs under the Clean Air Act. This final action affects the EPA's implementation of the new source review program because of the lower “major stationary source” threshold triggered by reclassification (CAA 189(b)(3)). The final action may also affect new or modified stationary sources proposed in these areas that require f ederal permits, approvals, or funding. Such projects are subject to the requirements of the EPA's General Conformity rule, and f ederal permits, approvals, or funding for the projects may be more difficult to obtain because of the lower de minimis threshold s triggered by reclassification.
Given these potential implications, consistent with the EPA Policy on Consultation and Coordination with Indian Tribes, the EPA contacted tribal officials early in the process of developing this regulation to permit them to have meaningful and timely input into its development. The EPA invited tribal officials to consult during the development of the proposed rule and following signature of the proposed rule. As discussed in more detail in our proposed action, we sent letter s to leaders of the tribes with areas of Indian country in the S outh CoastThis document is a prepublication version signed by EPA Regional Administrator Jared Blumenfeld on Dec ember

cont inue to invite Indian tribes in the S outh Coast to contact the EPA with any questions about the effects of this reclassification on tribal interests and air quality.
G. Executive Order 13045, Protection of Children From Environmental Health Risks and Safet y Risks
The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2

- 202 of the Executive Order. This action is not subject to Executive Order 13045 because it reclassifies the South Coast nonattainment area as Serious nonattainment for the 2006 PM 2.5 NAAQS, which tri ggers additional Serious area planning requirements under the CAA. This action does not establish an environmental standard intended to mitigate health or safety risks.

The EPA believes the human health or environmental risk addressed by this action will not have potential disproportionately high and adverse human health or environmental effects on minority, low

- income or indigenous populations. This action rec lassifies the South Coast nonattainment area as Serious nonattainment for the 2006 PM 2.5 NAAQS, which triggers additional Serious area planning requirements under the CAA.
