3 On November 9, 2011, the E PA partially approved and partiall y disapproved the San Joaquin Valley PM 2.5 State Implementation Plan ( “ SJV PM 2.5 SIP ” ) (76 FR 69896) . The SJV PM 2.5 SIP is California’s plan for attain ing the 1997 PM 2. 5 NAAQS in the San Joaquin Valley

. 1 Our partial disapproval of the SJV PM 2.5 SIP was based on our determination that its contingency measure provisions failed to meet the requirements of Clean Air Act ( “ CAA ” or “ the Act ” ) section 172(c)(9 ) , which require that the SIP for each PM 2.5 nonattainment area contain contingency measures to be implemented if the area fails to make reasonable further progress (RFP) or to attain the NAAQS by the applicable attainment date. See 76 FR 41338, 41357 to 41359 (July 13, 2011) (proposed partial approv al and partial disapproval of SJV PM 2.5 SIP) and 76 FR 69896, 69918 to 69919 and 69924 (final partial approval and partial disapproval of SJV PM 2.5 SIP)

. Th e disapproval became effective on January 9, 2012 , start ing a sanctions clock for imposition of

new source review offset sanctions 18 months after January 9, 2012, and highway sanctions 6 months after the imposition of offset sanctions , pursuant to CAA s ection 179 and our regulations at 40 CFR 52.31. On July 3, 2013, CARB submitted the Contingency Measur e SIP as a revision to the California State Implementation Plan. The Contingency Measure SIP addresses the SIP deficiencies identified in the EPA’s 2011 partial disapproval of the SJV PM 2.5 SIP by (1) confirming that the SJV area had met its 2012 RFP miles tones and (2) expanding upon the attainment contingency measures in the SJV PM 2.5 SIP to establish a contingency plan that achieves SIP

- creditable emission reductions equivalent to approximately one year’s worth of RFP in 2015. See generally Contingency Measure SIP. Among these SIP

4 reductions are reductions from a contingency provision in the District’s residential woodburning rule, Rule 4901 , and reductions from the District’s implementation of two incentive grant

. at 4 and 6. A detailed description of the Contingency Measure SIP can be found at 78 FR 53113, 53115 (August 28, 2013). On August 28 , 2013, we proposed to approve the Contingency Measure SIP as correcting the deficiency in the SJV PM 2.5 SIP related to the attainment contingency measure r equirement (78
FR 53113 ) . At the same time, we also proposed to find , based on documentation in the Contingency Measure SIP, that the RFP contingency measure requirement in CAA section 172(c)(9) for the 2012 milestone year was moot because the SJV has achieved the emission reduction ben chmarks for the 2012 RFP year. O ur full evaluation of the Contingency Measure SIP and our rationale for finding that this SIP correct s the deficiencies in the SJV PM 2.5 SIP can be found in the August 28, 2013 proposed rule. B ased on our proposed approval of the Contingency Measure SIP, we also issued o n August 28, 2013, an interim final determination that stayed the imposition of the offset sanctions that became effective in the SJV on July 9, 2013 and tolled the sanctions clock for the imposition of the highway sanctions (78 FR 53038)

5 A . Comments regarding necessary types and quantities of contingency measure emission reductions Comment 1 : Earthjustice cites the D.C Circuit Court of Appeals’ decision in Natural Resources Defense Council v. EPA , 706 F.3d 428 (D.C. Cir. 2013) (hereafter “ NRDC ”) to support its claim that the Contingency Measure SIP cannot be approved under the CAA. Specifically, Earthjustice argues that the EPA’s approval of the SJV PM 2.5 SI P was built upon the EPA’s 2007 implementation rule for the 1997 PM 2.5 NAAQS (hereafter “2007 PM 2.5 Implementation Rule”), 2
which the NRDC court has since remanded for failure to comply with the requirements of subpart 4 of title I, part D of the CAA; that the SJV PM 2.5 SIP and the reasonable further progress (RFP) projections therein likewise fail to satisfy the applicable requirements of subpart 4; and that because the contingency measure obligation is based upon the RFP projections in the
SJV PM 2.5 SIP, the Contingency Measure SIP is also flawed. Earthjustice argues that the most significant defect in the SJV PM 2.5 SIP is that it assumes the maximum available attainment deadline without implementing best available control measures (BACM) under CAA sectio n 189(b)(1)(B), and that because of this erroneous attainment date the RFP trajectory in the SJV PM 2.5 SIP p rovides for a 9

- year attainment “glide path” that fails to comply with the CAA. Under subpart 4, Earthjustice argues, nonattainment areas relying on reasonably available control measures have four years to attain and thus have a contingency measure obligation of 25 percent of the total reductions required for attainment, rather than the

one - ninth of total reductions provided in the Contingency Measure SIP. Alternatively, Earthjustice argues that had the SJV qualified for an extended attainment deadline under CAA

2 See “Clean Air Fine Particle Implementation Rule,” 72 FR 20586 (April 25, 2007), codified at 40 CFR part 51, subpart Z.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

6 section 188(b)(1), the District would have had to implement BACM, which would have provide d for steeper emission reductions than currently provided in the SJV PM 2.5 SIP which is based on the implementation of reasonably available controls. Earthjustice further contends that because the SJV area has failed to attain the PM 2.5 standard by the “mod erate” area deadline in subpart 4, a new plan with new controls and an attainment horizon that is less than 9 years is required. Earthjustice states that this new plan must include new RFP targets and contingency measures, and that the calculation of these targets will require more than one

- ninth of the total reductions required, because the interval between the baseline for the serious area plan and the attainment deadline will be less than nine years. Thus, according to Earthjustice, “no matter how the SJ V chooses to comply with subpart 4, there is no scenario in which the RFP trajectory and therefore the quantity of emission reductions required for contingency measures will match those calculated in the [SJV PM 2.5 SIP].” Response 1 : As a threshold matter , to the extent the commenter is challenging our November 2011 final action on the SJV PM 2.5 SIP based on the D.C. Circuit’s January 2013 decision in
NRDC , such a challenge may only be brought in the appropriate circuit court within specified timeframes un der CAA section 307(b). Section 307(b)(1) provides, inter alia , that any petition for review of an EPA actio n in “approving or promulgating any implementation plan under [CAA section 110] * * * which is locally or regionally applicable may be filed only in the United States Court of Appeals for the appropriate circuit” and must be filed “within sixty days from the date notice of such promulgation, approval, or action appears in the Federal Register, except that if such petition is based solely on grounds ar ising after such sixtieth day, then any petition for review under this subsection shall be filed within sixty days after such grounds arise.” Our actionThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

7 today on the Contingency Measure SIP is not the appropriate forum for a challenge to our November 2011 final action on the SJV PM 2.5 SIP. We nonetheless respond below to the substance of Earthjustice’s claims. In NRDC , the U.S. Court of Appeals for the D.C. Circuit remanded the EPA’s 2007 PM 2.5 Implementation Rule, 3 holding that the EPA erred in implementing the 1997 PM 2.5 standards solely pursuant to the general implementation provisions of subpart 1 of part D, title I of the CAA, without also considering the particulate matter

- specific provisions of subpart 4. The court directed the EPA to

re - promulgate the rule pursuant to subpart 4 of part D, title I of the Clean Air Act but declined to impose a deadline by which the Agency must do so. See 706 F.3d 428 , 437 and n. 10. This decision has no bearing on our action on the Contingency Measure SIP. Earthjustice’s arguments rest on the premise that the NRDC decision necessarily invalidates our November 2011 final action on the SJV PM 2.5 SIP (76 FR 69896, November 9, 2011) and therefore renders flawed any assessment of cont ingency measure obligations derived from that plan. Nothing in NRDC , however, indicates the court intended to automatically invalidate other EPA rulemakings that were based in whole or in part on the 2007 PM 2.5 Implementation Rule

. Indeed, the D.C. Circuit remanded but did not vacate the 2007 PM 2.5 Implementation Rule, 4 citing in its opinion (at 706 F.3d at 437 n. 10) a prior decision in which it held that “it is appropriate to remand without vacatur in particular occasions where vacatur ‘would at least

tem porarily defeat ...the enhanced protection of the environmental values covered by [the EPA

3 The NRDC decision remanded both the 2007 PM 2.5 Implementation Rule and a separate rulemaking to implement the New Source Review permitting requirements for the 1997 PM 2.5 NAAQS . This latter rule is not at issue in this action. 4 The 2007 PM 2.5 Implementation Rule therefore remains “on the books” while the EPA effects the required changes through one or more national rulemakings consistent with the NRDC decision.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

8 rule at issue].’” North Carolina v. EPA, 550 F.3d 1176, 1178 (D.C. Cir. 2008). Our November 2011 final action on the SJV PM 2.5 SIP included approval of District commitm ents to adopt and implement specific control measures on a fixed schedule and State and District commitments to achieve specific amounts of NO x , SO x and direct PM 2.5 emission reductions by fixed dates

. See 76 FR 69896, 69924 (November 9, 2011), codified at 40 CFR 52.220(c)(392) and (c) (395). Absent an EPA rulemaking to withdraw or revise this final rule, which NRDC does not compel, our final action on the SJV PM 2.5 SIP remains effective and these State and District commitments remain federally

- enforceable r equirements of the California SIP. 5 We therefore disagree with the commenter’s assertion that the RFP projections in the SJV PM 2.5 SIP render the Contingency Measure SIP flawed. Additionally, we do not believe that the NRDC court’s January 4, 2013 decision should be interpreted so as to retroactively impose subpart 4 requirements on the state in the context of our action on this corrective SIP, as the timing and nature of the court’s decision compound the consequences of disapproval based on such retroactiv e application here. 6 California submitted the various components of the SJV PM 2.5 SIP (and revisions thereto) between June 2008 and July 2011. On July 13, 2011, we proposed to approve all elements of the SJV PM 2.5 SIP except for its

5 To remove the se commitments from the applicable SIP before the EPA has re

- promulgated an implementation rule pursuant to subpart 4 consistent with the NRDC opinion would be to temporarily defeat the enhanced environmental protections provided by these federally

enforce able control obligations. 6 In rulemakings on individual areas subsequent to the NRDC decision, the EPA has explained in detail its view that the court’s recently announced interpretation should not be applied retroactively. See, e.g., 78 FR 20856 (April 8 , 2013) (proposed redesignation of Indianapolis to attainment for 1997 annual PM 2.5 standard) and 78 FR 41698 (July 11, 2013) (final redesignation of Indianapolis to attainment for 1997 annual PM 2.5 standard). The U.S. District Court for the District of Co lorado recently agreed with the EPA’s position that NRDC does not require retroactive application of Subpart 4 requirements. See Wildearth Guardians v. Gina McCarthy, Case No. 13

9 contingency measure pro visions and described the specific deficiencies in the contingency measures that California would need to address in a corrective SIP submission in order to avoid mandatory sanctions ( 76 FR 41338 , 41358 to 41359, 41361 , July 13, 2011). We finalized this
pa rtial approval and partial disapproval action on November 9, 2011, effective January 9, 2012, starting a sanctions clock for imposition of offset sanctions 18 months after January 9, 2012 and highway sanctions 6 months later, pursuant to CAA section 179(b) and the EPA’s regulations at
40 CFR 52.31 ( 76 FR 69896, 69924 , November 9, 2011) (final rule partially approving and partially disapproving SJV PM 2.5 SIP) )

. 7 We stated in the final rule that “[n]either sanction [would] be imposed under the CAA if Californ ia submits and we approve prior to the implementation of the sanctions, SIP revisions that correct the deficiencies identified in our proposed action.” Id. California reasonably relied upon this statement to develop a SIP submission addressing the deficiencies identified in the July 2011 proposed action

– i.e. , a SIP submission containing contingency measures that achieve emission reductions equivalent to on e year’s worth of RFP, on a pollutant

- specific basis, which are in excess of the emission reductions relied on for RFP and attainment in the SJV PM 2.5 SIP ( 76 FR 41338 , 41358 to 41359, 41361 , July 13, 2011). Over a year later, on January 4, 2013, the D.C. Circuit issued its decision remanding the EPA’s 2007 PM 2.5 Implementation Rule. By this time, just six months remained before mandatory offset sanctions would apply in the SJV under CAA section 179(b) unless the State submitted and we approved a SIP revis ion correcting the deficiencies that prompted the EPA’s

7 The disapproval also triggered an obligation on the EPA under CAA section 110(c)(1) to promulgate a federal implementation plan to address the deficiency unless the State submits and the EPA approves a plan revision correcting the deficiency within two years ( 76 FR 69896, 69924 , November 9, 2011).This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

10 disapproval. On June 20, 2013, the District adopted the Contingency Measure SIP, which it had developed to address the deficiencies identified in the 2011 action on the SJV PM 2.5 SIP, and CARB submitt ed this corrective SIP on July 3, 2013

. 8 We proposed to approve the Contingency Measure SIP on August 28, 2013 ( 78 FR 53113 )

. Concurrently, we issued an interim final determination to stay offset sanctions and defer highway sanctions in the SJV are a, based on our

“ proposal to approve the State’s SIP revision as correcting the deficiency that initiated these
sanctions ” ( 78 FR 53038 , August 28, 2013 )

. 9 To disapprove this corrective SIP submission now, based on a retroactive application of subpart 4 requiremen ts to the SJV PM 2.5 SIP, would immediately subject the SJV area to offset sanctions and highway sanctions under the EPA’s sanction application sequencing rule in 40 CFR 52.31(d)(2)(ii). 10 We believe it would be unreasonable to now disapprove this SIP submis sion, which corrects the deficiencies we had identified, and subject the SJV area to mandatory sanctions solely because the State did not address subpart 4 requirements of which it had no notice. 11

8 Letter dated July 3, 2013 , from Richard W. Corey, Executive Officer, California Air Resources Board, to Jared Blume nfeld, Regional Administrator, U.S. EPA Region 9, transmitting the San Joaquin Valley Air Pollution Control District’s “Quantification of Contingency Reductions for the 2008 PM 2.5 Plan” (adopted June 20, 2013), with enclosures. 9 Under 40 CFR 52.31(d)(2)(i i), during the period between 18 and 24 months following the EPA’s disapproval of a plan submission, offset sanctions are stayed and highway sanctions deferred if the EPA proposes to approve a revised plan submitted by the State and issues an interim final determination that the revised plan “corrects the deficiency prompting the [disapproval] .” 10 The offset sanction initially applied in the SJV area on July 9, 2013 ( 78 FR 53038 , August 28, 2013). Thus, under 40 CFR 52.31(d)(2)(ii), the offset sanction woul d reapply on the date the EPA issued a proposed or final disapproval and the highway sanction would apply immediately because more than 6 months have passed since initial application of the offset sanction. 11 As the U.S. District Co u rt for the District o f Colorado recently stated, “retroactive application of Subpart 4 to impose deadlines of which the States were not previously aware would be unfair and contrary to the state/federal balance outlined in the CAA.” See Wildearth Guardians v. Gina McCarthy, Case No. 13

11 Moreover, it is not clear what RFP projections would result from the new subpart 4 plan that Earthjustice calls for and, consequently, it is impossible for the State to quantify a contingency measure obligation based on such a new plan before it is develop ed. 12 It would be even more unreasonable to disapprove this corrective SIP submission on the basis of RFP trajectories that cannot currently be ascertained, particularly given the lengthy rulemakings that would be necessary for the State to develop a new pl an under subpart 4 with new RFP targets and a new attainment deadline, and the likely economic hardship that would result from continued application of mandatory offset and highway sanctions during this time

. The D.C. Circuit recognized the inequity of thi s type of retroactive impact in Sierra Club v. Whitman, 285 F.3d 63 (D.C. Cir. 2002), where it upheld the district court’s ruling refusing to make retroactive the
EPA ’s determination that the St. Louis area did not meet its attainment deadline. In that cas e, petitioners urged the court to make the EPA ’s nonattainment determination effective as of the date that the statute required, rather than the later date on which the EPA actually made the determination. The court rejected this view, stating that applyin g it “would likely impose large costs on the States, which would face fines and suits for not implementing air pollution prevention plans * * * even though they were not on notice at the time.” Id. at 68 . Similarly, it would be unreasonable to penalize Cal ifornia by rejecting this corrective SIP on the basis of subpart 4 requirements of which the State was unaware when we partially disapproved the SJV

12 As the EPA explained in the preamble to the 2007 PM 2.5 Implementation Rule, contingency measures should provide for emission reductions equivalent to about one year of reductions needed for RFP, based on the overall level of reductions needed to demonstrate attainment divided by the number of years from the “ base year” to the attainment year ( 72 FR 20586, 20643 , April 25, 2007). Thus, without first establishing the relevant base year, the attainment year, and the overall level of reductions needed to demonstrate attainment, and then considering whether availab le controls (whether RACM or BACM) might expedite the attainment date, it is impossible to determine the rate of emission reductions that would demonstrate RFP and the corresponding amount of emission reductions that would be equivalent to about one year o f RFP.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

12 PM 2.5 SIP , particularly when relief from mandatory sanctions would not be available until after the State c ompletes a lengthy rulemaking process to adopt an entirely new plan under subpart 4. In separate rulemakings, t he EPA has taken steps to respond to the NRDC decision by address ing the applicable requirements of subpart 4 for areas designated nonattainment for the 1997 PM 2.5 NAAQS and/or the 2006 PM 2.5 NAAQS

. For example, the EPA recently completed a rulemaking to classify all PM 2.5 nonattainment areas nationwide, including the San Joaquin Valley, as “moderate” nonattainment under subpart 4 and to establish a December 31, 2014 deadline for the states to submit any additional SIP revisions that may be necessary to satisfy the requirements applicable to moderate nonattainment areas under CAA section 189(a). See 78 FR 69806 (November 21, 2013) (proposed rule) an d “Identification of Nonattainment Classification and Deadlines for Submission of State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM 2.5 ) National Ambient Air Quality Standard (NAAQS) and 2006 PM 2.5 NAAQS,” si gned April 25, 2014 (fin al rule , pre - publication copy ) . As explained in that rulemaking, the EPA recognizes that prior to the D.C. Circuit’s decision in NRDC , states have worked towards meeting the air quality goals of both the 1997 PM 2.5 standards and the 2006 PM 2.5 standards in accordance with EPA regulations and guidance derived from subpart 1, including the requirements of the 2007 PM 2.5 Implementation Rule ( 78 FR 69806, 69809 )

. Taking this history into account, the EPA concluded that a December 31, 2014 deadline w ould provide states a relatively brief but reasonable amount of time to ascertain whether and to what extent any additional SIP submissions would be needed to satisfy the applicable requirements of subpart 4 in a particular nonattainment area and to develo p, adopt and submit any such SIPs. See id. The EPA explicitly stated that this rulemaking “does not affect any action that the EPA hasThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

13 previously taken under section 110(k) of the Act on a SIP for a PM 2.5 nonattainment area.” Id. at 69810. Accordingly, Cal ifornia is obligated to consider whether and to what extent any additional SIP submissions may be required to satisfy the applicable requirements of subpart 4 for the 1997 and/or 2006 PM 2.5 NAAQS in the SJV and to develop, adopt and submit any such SIPs,
f ollowing reasonable notice and public hearings, no later than December 31, 2014. In the meantime, our November 2011 final action remains in effect and continues to provide the appropriate basis for calculating the required quantity of emission reductions i n this corrective SIP. We believe it is appropriate to address the NRDC decision on a prospective rather than retrospective basis by maintaining the environmental benefits of air quality plans that the EPA has previously approved while working with state a nd local agencies to supplement these prior submissions as necessary going forward. Our approval of the Contingency Measure SIP today does not obviate the State’s obligation to submit these additional SIP revisions, consistent with the requirements of subp art 4, including additional contingency measures as necessary. Comment 2 : Earthjustice argues that the EPA cannot claim that the Contingency Measure SIP and the SJV PM 2.5 SIP are consistent with the implementation rule remanded by the D.C. Circuit pending adoption of a new implementation rule. According to Earthjustice, subpart 4 is self

effectuating and directly

- enforceable and does not require EPA regulations in order for states to know their planning obligations

. Additionally, Earthjustice states that the EPA has already adopted guidance interpreting subpart 4 in “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 ”) and in “ S ta te Implementation Plans for Serious PM

14 Addendum to the General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990” (59 FR 41998, Au gust 16, 1994) (hereafter “ Addendum ”)

. According to Earthjustice, the requirements of subpart 4 are plain on their face and well understood, and the
NRDC holding means that these requirements have always applied to PM 2.5 nonattainment plans notwithstanding the EPA’s efforts to avoid them. Response 2 : It appears Earthjustice is arguing that NRDC compels us to disapprove the Contingency Measure SIP based on a retroactive application of subpart 4 requirements to the underlying SJV PM 2.5 SIP. We disagree with t his assertion. As explained above, we do not believe it would be reasonable to disapprove this corrective SIP based on a finding that the underlying attainment and RFP demonstrations in the SJV PM 2.5 SIP, which we fully approved in 2011, now fail to satisf y subpart 4 requirements of which the State had no notice. As discussed in our proposal (78 FR 53113, 53123), the Contingency Measure SIP corrects the deficiencies that prompted the partial disapproval of the SJV PM 2.5 SIP in 2011. We believe our approval of this corrective SIP submission today is appropriate in light of the State’s reasonable reliance on the 2011 final action, the significant consequences of a disapproval based on retroactive application of subpart 4 requirements in this context, and the E PA’s separate rulemaking to establish reasonable timeframes for states to submit additional SIPs that may be required to satisfy the requirements of under subpart 4.

. See General Preamble at 13543 to 13544 (discussing contingency measures for moderate PM 10 nonattainment areas); see also Addendum at 42014 to 42015 (discussing contingency measures for serious PM 10 nonattainment areas). We are approving t he Contingency Measure SIP because it meets these criteria as applied to the SJV PM 2.5 SIP and because it corrects the deficiencies that prompted t he 2011 partial disapproval of that plan ( 78 FR 53113, 53123 )

. Our approval of the Contingency Measure SIP today does not rest on a conclusion that compliance with the 2007 PM 2.5 Implementation Rule remanded by the court suffices to satisfy CAA requiremen ts pending adoption of a new implementation rule, nor does the EPA believe an implementation rule is necessary for states to know their planning obligations under subpart 4. Indeed, although the EPA has not yet issued a new or revised implementation rule c onsistent with the court’s directive in NRDC, the EPA has established a December 31, 2014 deadline for all states with PM 2.5 nonattainment areas to submit any additional SIPs that may be required under subpart 4, following consultation as appropriate with EPA regional offices. See “Identification of Nonattainment Classification and Deadlines for Submission of State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM 2.5 ) National Ambient Air

section 172(c)(9). Thus, even if we apply the subpart 4 requirements to our evaluation of the Contingency Measure SIP and disregard the provisions of the 2007 PM 2.5 Implementation Rule remanded by the NRDC court, the general requirem ent for contingency measures in CAA section 172(c)(9) continues to apply ( 78 FR 53113, 53115 n. 8 )

. Comment 3 : Earthjustice comments that the EPA cannot claim as a basis for approval that the Contingency Measure SIP satisf ies the obligations identified in the EPA’s 2011 final action on the SJV PM 2.5 SIP because that plan does not comply with the Act. Earthjustice contends that the approval of the Contingency Measure SIP would “compound the legal defects of the [SJV PM 2.5 SIP ]” and that we should act immediately to “call” the SJV PM 2.5 SIP under CAA section 110(k)(5) because we now know that the plan fails to comply with the requirements of the Act. In the meantime, Earthjustice assert s that we cannot add to the legal defects by approving contingency measures that are based on a defective plan. I n support of these arguments, Earthjustice cites Association of Irritated Residents v. EPA, 632 F.3d 584 (9th Cir. 2011), reprinted as amended on January 27, 2012, 686 F.3d 668, further amended February 13, 2012 (“ AIR ” )

. Response 3 : We disagree with these arguments. First, as discussed above, nothing in NRDC compels us to retroactively apply subpart 4 requirements to the SJV PM 2.5 SIP and to disapprove the Contingency Measure SIP on that basis

. Absent an EPA rulemaking to withdraw or revise our November 201 1 final action on the SJV PM 2.5 SIP (76 FR 69896, November 9, 2011), that final action remains effective and provides an appropriate basis for our evaluation of the State’s corrective SIP submission in accordance with the EPA’s long

17 Second, the EPA’s discretionary “SIP call” authority in CAA section 110(k)(5) is not relevant to this action as we have not made any of the findings that would obligate us to “call” the SJV PM 2.5 SIP . Section 110(k)(5) provides, in relevant part, that “[ w]henever the Administrator finds that the applicable implementation plan for any area is substantially inadequate to attain or maintain the relevant [NAAQS] . . . or to otherwise comply with any requirement of [the CAA],” the EPA “shall require the State to revise the plan as necessary to correct such inadequacies” and may establish reasonable deadlines, not to exceed 18 months after providing notice to the State, for the submission of such plan revisions. CAA section 110(k)(5), 42 U.S.C. 7410(k)(5). Shoul d we find that the SJV PM 2.5 SIP is “substantially inadequate to attain or maintain” the 1997 PM 2.5 NAAQS or to otherwise comply with any requirement of the Act, we would be obligated to require that California revise the plan as necessary to correct such inadequacies ( i.e. , to issue a “SIP call”) and would be authorized to establish reasonable deadlines for the State to submit such plan revisions, not to exceed 18 months after the EPA notifies the State of the inadequacies. To date, however, we have not ma de any such finding under section 110(k)(5) with respect to the SJV PM 2.5 SIP . The EPA believes that its recent rulemaking to classify all PM 2.5 nonattainment areas as “moderate” nonattainment and to set a December 31, 2014 deadline for subpart 4 SIP submi ssions provides a reasonable timeframe for California to develop, adopt and submit any additional SIP submissions that are necessary to comply with the requirements of subpart 4 in the San Joaquin Valley. See “Identification of Nonattainment Classification and Deadlines for Submission of State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM 2.5 ) National Ambient Air Quality Standard (NAAQS) and 2006 PM 2.5 NAAQS,” signed April 25, 2014 (final rule, pre

18 after this deadline for SIP submissions whether the PM 2.5 SIP for the SJV is substantially inadequate to comply with CAA requirements. Finally, the Ninth Circuit Court of Appeal’s decision in A IR is inapposite

. AIR involved our action on proposed revisions to the SIP for the one

- hour ozone standard for the Los Angeles

South Coast air basin ( 686 F.3d 668 at 671 ) . An approved SIP for the area was in place, but after conducting new modeling for the one

measures. Id

- 73. California later withdrew certain of the proposed additional control measures and the State specifically represented that the currently approved plan was not sufficient to provide for attainment. Id. We approved the control measures that had not been with drawn. Id. at 673. However, we disapproved the revised attainment demonstration because California had substantially based it upon emission reductions resulting from the withdrawn control measures. Id. This disapproval left in place the existing attainment demonstration, which the State had specifically characterized as deficient. Id. The Ninth Circuit held that our action was arbitrary and capricious, because we had a duty under CAA section 110(l) to evaluate whether the SIP, as a whole, would provide for attainment of the NAAQS when the EPA approved a revision to the already approved SIP. Id. at 673

- 74. The circumstances here are significantly different from those in AIR . First, nothing in the record indicates that California considers any element of the currently approved SJV PM 2.5 SIP insufficient to provide for attainment of the 1997 PM 2.5 standards. Second, the Contingency Measure SIP neither revises nor replaces the attainment demonstration in the currently approved plan, nor does it alter any existin g emission limitation or other control requirement in the applicable SIP. Finally, California has not withdrawn any control measure s that provide emissionThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

19 reductions necessary for attainment of the 1997 PM 2.5 standards; to the contrary, the Contingency
Mea sure SIP expands upon the contingency measure portion of the SJV PM 2.5 SIP by providing additional NO x , SO x , and direct PM 2.5 emission reductions beyond those relied upon for RFP and attainment in the SJV PM 2.5 SIP , thereby correcting the deficiency that w e had identified in 2011 ( 78 FR 5311, 53123 ) . In sum, nothing in the Contingency Measure SIP revises the currently approved attainment demonstration in the SJV PM 2.5 SIP , nor does any information in the State’s submissions raise a question about the plan’s sufficiency to provide for timely attainment of the 1997 PM 2.5 standards. The AIR decision therefore is not pertinent to our action. For these reasons, we disagree with the commenter’s claim that our approval of the Contingency Measure SIP would “compound” or “add to” existing legal defects in the SJV PM 2.5 SIP . Because our approval of the Contingency Measure SIP strengthens the SIP and does not interfere with the on

- going process for ensuring that requirements for RFP and attainment of the 1997 P M 2.5 NAAQS are met, we find that it complies with CAA section 110(l). To the extent California is obligated to submit additional SIP revisions consistent with subpart 4 requirements by December 31, 2014, these outstanding obligations do not preclude approv al today of the Contingency Measure SIP as adequate to correct prior SIP deficiencies that triggered sanctions clocks. See Response 1

. Comment 4: Earthjustice comments that the SJV PM 2.5 SIP fails to properly address PM 2.5 precursor emissions and that the EPA approved the plan based on the “illegal presumption” in the 2007 PM 2.5 Implementation Rule that VOC and ammonia need not be controlled. Earthjustice argues that because the NRDC court has rejected this presumption, without a showing that sources of the se precursor emissions do not contribute significantly to PM 2.5 levels, they are subject to controls and therefore subject to separate contingency measure targets.

20 further argues that the San Joaquin Valley APCD has made no such demonstration and that “the record currently before EPA suggests that these emissions do contribute significantly to ambient levels even though the District believes that a strategy focusing on oxides of nitrogen is better policy

. ” In support of these arguments, Earthju stice references our responses to comments regarding VOCs in our final action on the SJV PM 2.5 SIP (76 FR 69896, 69902). Response 4: To the extent the commenter is challenging the November 2011 final action on the
SJV PM 2.5 SIP base d on the D.C. Circuit’s January 2013 decision in NRDC , such a challenge may only be brought in the U.S. Court of Appeals for the appropriate circuit within specified timeframes under CAA section 307(b). We are today acting on a SIP revision submitted by the State to correct SIP deficiencies that prompted sanctions, and comments concerning the analyses underlying the November 2011 action on the SJV PM 2.5 SIP are not germane to this action. See Response 1. As discussed above , the November 2011 final action on the SJV PM 2.5 SIP remains in effect and we believe that it would be unreasonable to retroactively apply the requirements of subpart 4 to our prior evaluation of the PM 2.5 precursor assessment in the SJV PM 2.5 SIP . Although the EPA has taken steps in a sepa rate rulemaking to respond to the NRDC decision regarding subpart 4 and is requiring all states with PM 2.5 nonattainment areas, including California, to submit SIP revisions as necessary to address subpart 4 requirements no later than December 31, 2014, th at rulemaking specifically notes that it does not affect any action that the EPA has previously taken under CAA section 110(k) on a SIP for a PM 2.5 nonattainment area. See 78 FR 69806, 69810 (November 21, 2013) and “Identification of Nonattainment Classifi cation and Deadlines for Submission of State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM 2.5 ) National Ambient Air Quality Standard (NAAQS) and 2006 PM 2.5 NAAQS,” signed April 25,This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

21 2014 (final rule, pre

- publication copy). Accordingly , the RFP demonstration in the SJV PM 2.5 SIP remains the appropriate basis for our evaluation of the specific types and amounts of emission reductions provided by the Contingency Measure SIP at this time. See Response 1. Even if the EPA takes the view that NRDC compels us to retroactively apply the requirements of subpart 4 to our prior evaluation of the PM 2.5 precursor assessment in the SJV
PM 2.5 SIP , it is not clear at this time how such a reevaluation would affect the a ssessment of required contingency measures

. T he D.C. Circuit remanded the EPA ’s 2007 PM 2.5 Implementation Rule , including the presumptions concerning VOC and ammonia in 40 CFR 51.1002. 14 While expressly declining to decide the specific challenge to these pr esumptions ( see 706 F.3d at 437, n. 10 (D.C. Cir. 2013) ), the court cited CAA section 189(e) 15 to support its observation that “[a] mmonia is a precursor to fine particulate matter, making it a precursor to both PM 2.5 and PM 10 ” and that “[f] or a PM 10 nonatta inment area governed by subpart 4, a
precur sor is presumptively regulated.” 706 F.3d at 43 6, n. 7 ( citing CAA section 189(e), 42
U .S.C. 7513a(e)). The NRDC court did not, however, address whether and how it was substantively necessary to regulate any speci fic precursor in a particular PM 2.5 nonattainment

area . Moreover, even assuming both VOC and ammonia must be regulated for purposes of

14 The 2007 PM 2.5 Implementation Rule contained rebuttable presumptions concerning certain PM 2.5 precursors applicable to attainment plans and control measur es related to those plans. Specifically, in 40 CFR 51.1002(c), the EPA provided, among other things, that a state was “not required to address VOC [and ammonia] as * * * PM 2.5 attainment plan precursor[s] and to evaluate sources of VOC [and ammonia] emissi ons in the State for control measures,” unless the State or the EPA provided an appropriate technical demonstration showing that emissions from sources of these pollutants “significantly contribute” to PM 2.5 concentrations in the nonattainment area ( 40 CFR 51.1002(c)(3), (4) )

. 15 CAA s ection 189(e) provides that control requirements for major stationary sources of direct PM 10 shall also apply to PM 10 precursors from those sources, except where the EPA determines that major stationary sources of such precurso rs “do not contribute significantly to PM 10 levels which exceed the standard in the area.”This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

22 attaining the 1997 PM 2.5 standards in the SJV, it is not clear what collection of control measures for which specific precursors would ultimately be necessary to satisfy the requirements in subpart 4 concerning reasonably available control measures (CAA section 189(a)(1)(C)), best available control measures (CAA section 189(b)(1)(B)), or quantitative milestones demonstrat ing RFP (CAA section 189(c)). See, e.g. , General Preamble at 13540 to 13541 (discussing technological feasibility, cost of control, and “de minimis” emission levels among factors to be considered in determining RACM and RACT for a particular PM 10 nonattain ment area); see also Addendum at 42011 to 42014 (distinguishing BACM from RACM standard and discussing factors to be considered in determining BACM and BACT for a particular PM 10 nonattainment area, including technological and economic feasibility). Given that it is thus currently impossible to identify the precise collection of control measures that would be necessary in a new subpart 4 plan, let alone to quantify the emission reductions that these measures would collectively achieve and then calculate the reductions that would be required for associated contingency measure
purposes, 16 we do not believe it would be reasonable to penalize the State at this time for failure to carry out these tasks in the past. The State and District must first address these i ssues as appropriate through adoption of a SIP revision satisfying the requirements of subpart 4, which is due December 31, 2014. Under the commenter’s read of NRDC , relief from mandatory sanctions for SIP deficiencies identified prior to the NRDC decision would be unavailable to California until it completes lengthy State and local rulemaking processes to develop and adopt an entirely new attainment plan that satisfies the requirements of subpart 4, requirements that are not yet due and that we

23 have not, t o date, identified as bases for plan disapproval. We decline to read the court’s decision in a way that would lead to such an inequitable and retroactive result. Comment 5: Earthjustice claims that the alleged legal defects of the SJV PM 2.5 SIP preclude t he EPA from determining that the proposed contingency measures are “beyond or in addition to” the core control requirements of the CAA. Earthjustice argues that this problem is most apparent
in the EPA’s treatment of the contingency provision in the Distri ct’s residential woodburning rule, Rule 4901. Citing our November 2011 responses to comments on the SJV PM 2.5 SIP (76 FR 69896, 69904), Earthjustice states that we did not require implementation of this me asure as a basic control measure on the basis that it would not “advance attainment” by at least a year and argues that this justification “is no longer sufficient if the area is subject to the [BACM] requirement, as it must be given that it has failed to attain within four years of its designation as

nona ttainment for PM 2.5 .” Earthjustice asserts that BACM are more stringent than reasonably available controls and cannot be rejected based on whether or not they advance attainment, and that credit for the Rule 4901 contingency measure is therefore inappropriate. Furthermore, Earthjustice asserts that our 2009 approval of Rule 4901 as BACM for PM 10 is “not sufficient for concluding that improvements such as those included in the proposed contingency measure are beyond [BACM]” as the necessary demonst ration has not been made and “there is no reason to believe that the lower trigger included in the proposed contingency measure is not technically feasible or cost

- effective.” Noting that the problems associated with PM 2.5 in the Valley are different than those associated with PM 10 , Earthjustice cites the preamble to the EPA’s 2007
PM 2.5 Implementation Rule (72 FR 20617) to support its conclusion that “past determinations on the adequacy of control measures cannot substitute for a new demonstration for a ne w state implementation plan.”This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

24 Response 5 : As noted above, it appears the commenter is challenging the November 2011 final action on the SJV PM 2.5 SIP based on the D.C. Circuit’s January 2013 decision in NRDC . Such a challenge, however, may only be brought in the U.S. Court of Appeals for the appropriate circuit within specified timeframes under CAA section 307(b). We are today acting on a SIP revision submitted by the State to correct SIP deficiencies that prompted sanctions, and comments concerning the ana lyses underlying the EPA’s November 2011 action on the SJV PM 2.5 SIP are not germane to this action. See Response 1

. We nonetheless respond below to the substance of the commenter’s claims. To the extent the commenter is arguing that our action today on th e Contingency Measure SIP constitutes a determination that the contingency provision in Rule 4901 is “beyond BACM,” this is incorrect. We have not yet made any determination concerning BACM for PM 2.5 in the SJV and make no such determination today, as the area has not been classified as a “Serious Area” area under subpart 4 and the State therefore has not submitted a Serious Area plan for SJV for any PM 2.5 standard. See CAA section 189(b)(1)(B) (requiring that “each State in which all or part of a Serious A rea is located” submit a plan for such area that includes BACM for the control of
PM 10 ) and section 189(b)(2) (requiring submission of BACM provisions “no later than 18 months after reclassification of the area as a Serious Area”). Although Earthjustice suggests that we are relying on the Agency’s prior (2009) approval of Rule 4901 as BACM for the control of
PM 10 as a basis for today’s action, this suggestion is also incorrect. As part of the 2011 action on the SJV PM 2.5 SIP, we concluded that the conting ency provision in Rule 4901 was not a required RACM under CAA section 172(c)(1) 17 and that it qualified for consideration as a contingency

25 measure because it provided emission reductions beyond those relied upon for RFP or attainment in that plan

. See 76 FR 41338, 41358 (July 13, 2011) and 76 FR 69896, 69904 and 69906 (November 9, 2011). We disagree with t he commenter ’s claim that we must now also conclude that th e contingency provision in Rule 4901 is not a required BACM under CAA section 189(b)(1)(B).
Lik ewise, we disagree with the commenter’s contention that our November 2011 rationale for not requiring implementation of this measure as a basic control measure ( i.e. , on the basis that it would not “advance attainment” by at least a year) is no longer suff icient because the area has failed to attain within four years of its designation as nonattainment for PM 2.5 and is, therefore, now subject to the BACM requirement. Under the CAA, BACM is required only for nonattainment areas classified as serious ( CAA sec tion 189(b)(1)(B) )

. The SJV area is currently classified as moderate nonattainment. See “Identification of Nonattainment Classification and Deadlines for Submission of State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM 2.5 ) National A mbient Air Quality Standard (NAAQS) and 2006 PM 2.5 NAAQS,” signed April 25, 2014 (final rule, pre

- publication copy). Whether or not the SJV area has attained the 1997 PM 2.5 standards to date, in the absence of an EPA rulemaking to re classify the area as a Serious Area under subpart 4, the requirement to submit a Serious Area plan that assures implementation of BACM does not apply ( CAA sections 189(b)(1)(B) and 189(b)(2) )

. We note also that the commenter’s reference to CAA section 188(c)(1) to support its contention that “[u]nder subpart 4, nonattainment areas relying on reasonably available controls have four years to attain” is not accurate. Section 188(c)(1) states that “[f]or a Moderate Area,

demonstration in the SJV PM 2.5 SIP did not rely on this prior action ( 76 FR 69896, 69904 and 69906 , November 9, 2011).This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

26 the attainment date shall be as expeditiously as practicable but no later than the end of the sixth calendar year after the area’s designation as nonattainment , except that, for areas designated nonattainment for PM 10 under section [107(d)(4) of the Act], the attainment date shall not extend beyond December 31, 1994 ” ( CAA section 188(c)(1), 42 U.S.C. 7513(c)(1) ) . It appears that the commenter is interpreting the exception specified in the last clause of this provision to mean that the SJV PM 2.5 nonattainment area must attain the 1997 PM 2.5 NAAQS within four years of its designation as nonattainment for these standards. By its terms, however, this provision establishes an attainment date that has long passed (December 31, 1994) and applies only to those areas that were designated by operation of law under CAA section 1 07(d)(4) as nonattainment for the PM 10 NAAQS, pursuant to the CAA Amendments of 1990. See CAA section 107(d)(4)(B), 42 U.S.C. 7407(d)(4)(B) (establishing nonattainment designations by operation of law for certain areas identified by the EPA as “Group I” ar eas prior to November 15, 1990 and areas where air quality monitoring data showed a violation of the PM

- 10 NAAQS before January 1, 1989). This provision and the December 31, 1994 attainment date specified therein do not apply for purposes of establishing t he applicable attainment date for an area designated nonattainment for the 1997 PM 2.5 NAAQS in 2005, such as the San Joaquin Valley. If and when the EPA reclassifies the SJV area from “moderate” to “serious” nonattainment
for a PM 2.5 standard under subpar t 4, 18 California will be obligated to submit, no later than 18 months after such reclassification, SIP provisions to assure that BACM for PM 2.5 shall be

18 Under CAA sections 188(b)(2) and 179(c), the EPA must determ ine no later than 6 months following the applicable attainment date for the 1997 PM 2.5 standards in the SJV (April 5, 2015), based on air quality data, whether the area attained the standards by that date. Should we determine that the SJV area has failed t o attain by April 5, 2015, the area will be reclassified by operation of law as a Serious Area and the State will be required to submit plan provisions consistent with the requirements of subpart 4 within 18 months.

27 implemented no later than 4 years after the date the area is reclassified, among other things ( CAA sections 189(b)(1)(B) and 189(b)(2) ) . Contingency measures for any new or revised plan submitted to address subpart 4 requirements would have to provide emission reductions beyond those relied upon in the control strategy for that plan ( i.e. , for a “ S eriou s A rea, ” measures that are “beyond BACM”). We note that the possibility that a measure may be r e quired as RACM or BACM in the future does not preclude its use as a contingency measure now. Likewise, an approval of a measure as a contingency measure now do es not preclude a future determination that it is a required RACM or BACM under subpart 4. As the EPA explained in the Addendum, “if all or part of the moderate area plan contingency measures become part of the required serious area control measures ( i.e. , BACM), then additional contingency measures must be submitted whether or not the previously submitted contingency measures had already been implemented.” Addendum at 42015. Comment 6: Earthjustice comments that because the RFP demonstration will change u nder a plan that complies with subpart 4, the assessment of the controls required for demonstrating RFP will also change. Earthjustice argues that without a new RFP demonstration, the EPA cannot determine whether the contingency measures are surplus to mea sures that are otherwise required by the Act. Response 6 : As explained above, we do not believe it would be reasonable to disapprove this corrective SIP based on a finding that the underlying attainment and RFP demonstrations in the
SJV PM 2.5 SIP, demonstrations that we fully approved in 2011, now fail to satisfy subpart 4 requirements of which the State had no notice. As discussed in our proposal (78 FR 53113, 53123), the Contingency Measure SIP corrects the deficiencies that prompted the par tial disapproval of the SJV PM 2.5 SIP in 2011.

28 submission today is appropriate in light of the State’s reasonable reliance on our 2011 final action, the significant consequences of a disapproval based on retro active application of subpart 4 requirements in this context, and the EPA’s separate rulemaking to establish reasonable timeframes for states to submit additional SIPs that may be required under subpart 4 consistent with the NRDC decision.

. B. Comments regarding emission reductions from waiver measures and incentive grant
programs Comment 7: Earthjustice comments that “Congress was not willing to let states merely ‘promise’ to protect air quality” and that CAA section 110(a) requires states t o formulate plans for meeting and maintaining compliance with the NAAQS which “include enforceable emission limitations and other control measures, means or techniques (including economic incentives such as fees, marketable permits, and auctions of emissio ns rights) . . . as may be necessary or appropriate to meet the applicable requirements of this chapter . . . .” Earthjustice states that even those nontraditional techniques for reducing pollution (economic incentives, marketable permits, and auctions of emissions rights) authorized by section 110(a)(2)(A) must be “enforceable,” meaning
that the EPA and citizens must have the ability to bring enforcement actions to assure compliance. Earthjustice further asserts that “[a] state cannot claim SIP credit from control measures that shield pollution sources from independent enforcement actions.” In support of these statements, Earthjustice references the EPA’s statements in “State Implementation Plans; General Preamble for the Implementation of Title I of the Cl ean Air Act Amendments of 1990” (57 FR 13498, April 16, 1992) (hereafter “General Preamble”); “Improving Air Quality with Economic Incentive Programs,” U.S. EPA, Office of Air and Radiation, January 2001 (EPA

- HQ

- OAR

- 2012

- 0322) (hereafter “2013 SSM Memo”). Response 7: We agree generally with the statement that the CAA requires states to submit implementation plans including measures that the EPA and citizens can enforce. As the
commenter notes, the EPA has long interpreted CAA section 110(a) to mean that control measures and other means of a chieving emission reductions in a SIP, including “nontraditional techniques for reducing pollution [such as] economic incentives, marketa ble permits, and auctions of emissions rights,” must be “enforceable” ( General Preamble at 13556 )

. We disagree, however, with Earthjustice’s suggestion that the emission reductions identified in the Contingency Measure SIP are not enforceable because they are based on “measures that shield pollution sources from independent enforcement actions.” As explained below in Response 8 through Response 15 , all of the measures relied upon in the Contingency Measure SIP are directly enforceable by the State and/or Di strict against pollution sources, and the District’s commitments concerning the incentive

- based emission reductions are also enforceable by the EPA and citizens under the CAA. N othing in the Contingency Measure SIP “shields” pollution
sources from enforcem ent actions brought by the State or District. See Response 8 through Response 15. Comment 8: Earthjustice highlights both the EPA’s enforcement authority in CAA section 113 and the citizen suit provision in CAA section 304 as indication that “Congress was not willing to rely on states alone to guarantee that the claimed emission reductions would occur or be enforced.” Citing Pennsylvania v.

30 (1986), Earthjustice states that “[t]he Supreme Court has found that ‘Congress enacted 304 specifically to encourage citizen participation in the enforcement of standards and regulations established under this Act, and intended the sect ion to afford citizens very broad opportunities to participate in the effort to prevent and abate air pollution. ’ ” Additionally, Earthjustice states that “[t]his notion th at SIPs must be built upon emission reductions that are capable of being enforced by EPA and citiz ens pervades a number of EPA policies regarding SIP approvability.” For example, Earthjustice states that the “EPA will not approve control measures that include ‘director discretion’ to define or redefine compliance requirements” and that the EPA also will “not allow SIPs to include state affirmative defenses that would foreclose EPA or other enforcement.” In support of these statements, Earthjustice references EPA statements in the 2013 SSM Memo and in a memorandum dated September 20, 1999, f rom Steven A. Herman, Assist ant Admin istrator for Enforcement and Compliance, to Regional Administrators, entitled “State Implementation Plans (SIPs): Policy Regarding Excess Emissions During Malfunctions, Startup, and Shutdown” (hereafter “1999 SSM Guidan ce”). Earthjustice asserts that the two main contingency measures relied upon by the District

– excess emission reductions from State mobile source measures and emission reductions achieved through incentive programs

– fail to meet these criteria for enfor ceability. Response 8: We agree generally with the commenter’s statement that SIPs must be built upon
emission reductions that the EPA and citizens can enforce under CAA sections 113 and 304, respectively. We disagree, however, with the commenter’s asserti on that the contingency measures relied upon by the District contain any impermissible “director discretion” or “affirmative defense” provisions that may bar EPA or citizen enforcement of these measures or otherwise fail to meet the Act’s requirements for enforceability.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

31 As Earthjustice correctly states, the EPA has stated in long

- standing policy that it would not approve into a SIP any “director discretion” or “affirmative defense” provision that would bar
the EPA or citizens from enforcing applicable SIP requirements, as such provisions would be inconsistent with the regulatory scheme established in title I of the Act. See 2013 SSM Memo at
11

- 13 (quoting 1999 SSM Guidance at 3). Although some degree of state/local agency discretion in a SIP rule may be per missible if explic it and replicable procedures within the rule tightly define how the discretion will be exercised to assure equivalent emission reductions, the EPA has long stated that SIP provisions that include unbounded discretion for state personnel

u nilaterally to change or to grant variances from applicable SIP provisions are problematic and inconsistent with the requirements of the CAA. See “Guidance Document for Correcting Common VOC and Other Rule Deficiencies (a.k.a. The Little Bluebook),” U.S. E PA Region IX, originally issued April 1991, revised August 21, 2001; see also 78 FR 12460 , 12485 to 12 48 6 ( February 22, 2013 ) (proposed findings of substantial inadequacy and SIP calls to amend provisions applying to excess emissions during periods of star tup, shutdown, and malfunction) and 2013 SSM Memo at 13. With respect to “affirmative defenses,” 19 the EPA has stated in long

standing policy that a state may include in a SIP certain narrowly drawn affirmative defense provisions, which qualifying sources m ay utilize in enforcement proceedings under specified circumstances, but that a SIP may not contain any defense to injunctive relief or any provision that would enable a state to bar EPA or citizen enforcement of applicable requirements. See 2013
SSM Memo at 11

- 13; see also 1999 SSM Guidance at 2.

19 The term “affirmative defense” means, in the context of an enforcement proceeding, a response or defense put forward by a defendant, regarding which the defendant has the burden of proof, and the merits of which are independently and objectively evalua ted in a judicial or administrative proceeding.

32 Nothing in the Contingency Measure SIP authorizes either CARB or the District to modify the requirements of the SIP. As explained below in Response 13 , the District has submitted enforceable commitme nts to account for specified amounts of NO x and PM 2.5 emission reductions to be achieved in 2015 through incentive programs and to adopt and submit substitute measures on a fixed schedule if the identified programs fail to achieve these emission reductions in 2015. Since the EPA is approving these commitments into the SIP, the y are federally enforceable requirements of an applicable implementation plan, which cannot be modified except through a SIP revision adopted by the State after reasonable notice and p ublic hearing and approved by the EPA through notice

- and

- comment rulemaking. See CAA sections 110(l) and 302(q), 5 U.S.C. section 553, and 40 CFR 51.105. Additionally, nothing in the Contingency Measure SIP creates grounds for an affirmative defense that c ould be used in proceedings to enforce the District’s SIP commitments, nor does the Contingency Measure SIP contain any provision that could bar EPA or citizen enforcement of these SIP commitments. We therefore disagree with the commenter’s suggestion that the Contingency Measure SIP contains any “director discretion” or “affirmative defense” provision that would undermine the enforceability
of these emission reductions. We explain more fully below how the District’s SIP commitments

can be enforced by the E PA and citizens. See Response 10 through Response 15

. In addition, the EPA disagrees with the commenter’s assertion that the CARB mobile source control measures relied upon in the Contingency Measure SIP are not creditable as contingency

measures. As expla ined in Response 9 below, the EPA has historically allowed emission reduction credit for California motor vehicle emissions standards that have received waivers of federal preemption pursuant to the waiver approval process of CAA section 209 (“waiver

measu res”), without requiring California to submit the standards themselves to the EPA forThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

33 approval as part of the California SIP. See, e.g. , 76 FR 69896 (November 9, 2011) (final rule partially approving and partially disapproving SJV PM 2.5 SIP) and 77 FR 1265 2 (March 1, 2012) (final rule approving SJV 8

- hour Ozone SIP). Waiver measures are substituted for federal mobile source control measures in California, and they become enforceable by the State once the EPA issues a waiver or authorization. B ased on consid erations of permanence, enfor ceability, and quantifiability, the EPA continues to believe that it is appropriate and consistent with the CAA to allow California to rely on emission reductions resulting from waiver measures in SIPs. See Response 9

. Comme nt 9: Earthjustice states that most of the CARB mobile source control measures relied upon to provide excess emission reductions are not approved into the SIP and, therefore, are not enforceable by the EPA or through independent citizen enforcement. Earthjus tice states that the EPA is aware of this issue from previous comments on the 2008 PM 2.5 Plan and incorporates those comments by reference. 20 Earthjustice contends that because “the State is free to amend or rescind these measures altog ether without EPA ove rsight,” these emission reductions are not creditable as contingency measures.

20 Specifically, the commenter states: “As EPA is well aware from previous comments on the 2008 PM 2.5 Plan (incorporated by reference here), most of the CARB mobile so urce control measures relied upon here to provide excess emission reductions are not actually approved into the state implementation plan. As a result, they are not enforceable by EPA or through independent citizen enforcement . . . .” See letter dated Sep tember 27, 2013, from Paul Cort , at 7. Given the context of this comment and the broa d range of issues raised by commenters during the EPA’s previous rulemaking on the 2008 PM 2.5 Plan (referred to herein as the “SJV PM 2.5 SIP”), we assume Earthjustice inte nded here to incorporate by reference only those of its own comments address ing the EPA’s treatment of CARB mobile source control measures in the SIP ( see letter dated August 12, 2011 , from Paul Co rt, Staff Attorney, and Sarah Jackson, Research Associate, Earthjustice, “Comments on EPA’s Partial Approval/Disapproval of the San Joaquin Valley’s State Implementation Plan for Fine Particulate Matter, Docket # EPA

34 Response 9 : We disagree with the commenter’s argument that emission reductions from CARB mobile source control measures may not be credited as contingency measures. The EPA bel ieves that credit for emission reductions from implementation of California mobile source rules that are subject to CAA section 209 waivers (“waiver measures”) is appropriate notwithstanding the fact that such rules are not app roved as part of the Californ ia SIP. In our July 13, 2011 proposed action on the SJV PM 2.5 SIP and the technical support document for that proposal , we explained why we believe such credit is appropriate. See 76 FR 41338, 41345 (July 13, 2011) and “Technical Support Document and Respo nses to Comments, Final Rule on the San Joaquin Valley 2008 PM 2.5 State Implementation Plan ,” U.S. EPA Region 9, September 30, 2011 (hereafter “ 2011 Final TSD ”) at 101

- 105

. Historically, the EPA has granted credit for the waiver measures because of special Congressional recognition, in establishing the waiver process in the first place, of the pioneering California motor vehicle control program and because amendments to the CAA (in 1977) expanded the flexibility granted to California in order "to afford Cal ifornia the broadest possible discretion in selecting the best means to protect the health of its citizens and the public welfare," (H.R. Rep. No. 294, 95th Congr., 1st Sess. 301

- 2 (1977)). In allowing California to take credit for the waiver measures notw ithstanding the fact that the underlying rules are not part of the California SIP, the EPA treated the waiver measures similarly to the Federal motor vehicle control requirements, which the EPA has always allowed States to credit in their SIPs without subm itting the program as a SIP revision. As we explained in the 2011 Final TSD (p. 87), credit for Federal measures, including those that establish on

- road and nonroad standards, notwithstanding their absence in the SIP, is justified by reference to CAA secti on 110(a)(2)(A), which establishes the following content requirements for SIPs: “... enforceable emission limitations and other control measures, means, or techniques (includingThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

35 economic incentives such as fees, marketable permits, and auctions of emissions rights), ... , as may be necessary or appropriate to meet the applicable requirements of this chapter.” (emphasis added). Federal measures are permanent, independently enforceable (by the EPA and citizens), and quantifiable without regard to whether they are approved into a SIP, and thus the EPA has never found such measures to be “necessary or appropriate” for inclusion in SIPs to meet the applicable requirements of the Act. CAA s ection 209 establishes a process under which the EPA allows California’s waiver measures to substitute for Federal measures, and like the Federal measures for which they substitute, the EPA has historically found, and continues to find, based on considerations of permanence, enforceability, and quantifiability, that such measures are not “necessary or appropriate” for California to include in its SIP to meet the applicable requirements of the Act. First, with respect to permanence , we note that, to maintain a waiver, CARB’s on - road waiver measures can be relaxed only to a level of ag gregate equivalence to the Federal Motor Vehicle Control Program (FMVCP) (CAA section 209(b)(1) ) . In this respect, the FMVCP acts as a partial backstop to California’s on

- road waiver measures (i.e., absent a waiver, the FMVCP would apply in California). Li kewise, Federal nonroad vehicle and engine standards act as a partial backstop for corresponding California nonroad waiver measure s . The constraints of the waiver process thus serve to limit the extent to which CARB can relax the waiver measures for which there are corresponding the EPA standards, and thereby serve an anti

- backsliding function similar in substance to those established for SIP revisions in CAA sections 110(l) and 193. Meanwhile, the growing convergence between California and EPA mobile sourc e standards diminishes the difference in the emission reduction s reasonably attributed to the two programs and strengthens the role of the Federal program in serving as an effective backstop to the StateThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

36 program. In other words, with the harmonization of E PA mobile source standards with the corresponding State standards, the Federal program is becoming essentially a full backstop to most parts of the California program. Second, as to enforceability, we note that the waiver process itself bestows enforceabil ity onto California to enforce the on

- road or nonroad standards for which the EPA has issued the waiver. CARB has as long a history of enforcement of vehicle/engine emissions standards as the EPA, and CARB’s enforcement program is equally as rigorous as th e corresponding EPA program. The history and rigor of CARB’s enforcement program lends assurance to California SIP revisions that rely on the emission reduction s from CARB’s rules in the same manner as the EPA’s mobile source enforcement program lends assu rance to other state’s SIPs in their reliance

on emission reduction s from the FMVCP. While it is true that citizens and the EPA are not authorized to enforce California waiver measures under the Clean Air Act (i.e., because they are not in the SIP), citize ns and the EPA are authorized to enforce EPA standards in the event that vehicles operate in California without either California or EPA certification. As to quantifiability, the EPA ’s historical practice has been to give SIP credit for motor

vehicle

- related waiver measures by allowing California to include motor vehicle emissions estimates made by using California’s EMFAC (and its predecessors) motor vehicle emissions
factor model in SIP inventories. The EPA verifies the emission reduction s from motor

- vehicle

related waiver measures through review and approval of EMFAC, which is updated from time to time by California to reflect updated methods and data, as well as newly

- established e missions standards. ( Emission reduction s from the EPA ’s motor vehicle standards are reflected in an analogous model known as MOVES.) The EMFAC model is based on the motor vehicle emissions standards for which California has received waivers from the EPA bu t accounts forThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

37 vehicle deterioration and many other factors. The motor vehicle emissions estimates themselves combine EMFAC results with vehicle activity estimates, among other considerations. See the 1982 Bay Area Air Quality Plan, and the related the EPA rulemakings approving the plan ( see 48 FR 5074 (February 3, 1983) for the proposed rule and 48 FR 57130 (December 28, 1983) for the final rule) as an example of how the waiver measures have been treated historically by the
EPA in California SIP actions. 21 The SJV PM 2.5 SIP was developed using a version of the EMFAC model referred to as EMFAC2007, which the EPA has approved for use in SIP development in California. ( 73 FR 3464 , January 18, 2008). Thus, the emission reduction s that are from the California on

- road “waiver measures” and that are estimated through use of EMFAC are as verifiable as are the emission reduction s relied upon by states other than California in developing their SIPs based on estimates of motor vehicle emissions made through the use of t he MOVES model.

21 The EPA’s historical practice in allowing California credit for waiver measures notwithstanding the absence of the underlying rules in the SIP is further documented by reference to the EPA’s review and approval of a May 1979 revision to the California SIP entitled, “Chapter 4, California Air Quality Control Strategies.” In our proposed approval of the 1979 revision (44 FR 60758, October 22, 1979), we descr ibe the SIP revision as outlining California’s overall control strategy, which the State had divided i nto vehicular sources and non

vehicular (stationary source) controls. As to the former, the SIP revision discusses vehicular control measures as including technical control measures and transportation control measures. The former refers to the types of mea sures we refer to herein as waiver measures, as well as fuel content limitations, and a vehicle inspection and maintenance program. The 1979 SIP revision included several appendices, including appendix 4

– E, which refers to “ARB vehicle emission controls in cluded in title 13, California Administrative Code, chapter 3 * * *,” including the types of vehicle emission standards we refer to herein as waiver measures; however, California did not submit the related portions of the California Administrative Code (CA C) to the EPA as part of the 1979 SIP revision submittal. With respect to the CAC, the 1979 SIP revision states: “The following appendices are portions of the California Administrative Code. Persons interested in these appendices should refer directly to t he code.” Thus, the State was clearly signaling its intention to rely on the California motor vehicle control program but not to submit the underlying rules to the EPA as part of the SIP. In 1980, we finalized our approval as proposed ( 45 FR 63843 , Septemb er 28, 1980).This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

38 Moreover, the EPA ’s waiver review and approval process is analogous to the SIP approval process. First, CARB adopts its emissions standards following notice and comment procedures at the state level, and then submits the rules to the EPA as part of its waiver request. When the EPA receives new waiver requests from CARB, the EPA publishes a notice of opportunity for public hearing and comment and then publishes a decision in the Federal Register following the public comment period. Once again , in substance, the process is similar to that for SIP approval and supports the argument that one hurdle (the waiver process) is all Congress intended for California standards, not two (waiver process plus SIP approval process). Second , just as SIP revisi ons are not effective until approved by the EPA , changes to CARB’s rules (for which a waiver has been granted) are not effective until the EPA grants a new waiver, unless the changes are “within the scope” of a prior waiver and no new waiver is needed. Thi rd, both types of final actions by the EPA

— i.e., final actions on California requests for waivers and final actions on state submittals of SIPs and SIP revisions

— may be challenged under section 307(b)(1) of the CAA in the appropriate United States Court of Appeals. In the 2011 Final TSD (pp. 102

- 103), we indicated that we believe that section 193 of the CAA, the general savings clause added by Congress in 1990, effectively ratified our long

standing practice of granting credit for the California waiver rule s because Congress did not insert any language into the statute rendering the EPA 's treatment of California's motor vehicle standards inconsistent with the Act. Rather, Congress extended the California waiver provisions to most types of nonroad vehicles an d engines, once again reflecting Congressional intent to provide California with the broadest possible discretion in selecting the best means to protect the health of its citizens and the public welfare. Requiring the waiver measures to undergo SIP review in addition to the statutory waiver process is not consistent with providing California withThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

39 the broadest possible discretion as to on

- road and nonroad vehicle and engine standards, but rather, would add to the regulatory burden California faces in establi shing and modifying such standards, and thus would not be consistent with Congressional intent. In short, we believe that Congress intended California's mobile source rules to undergo only one the EPA review process (i.e., the waiver process), not two.
In summary, the EPA has historically given SIP credit for waiver measures in our approval of attainment demonstrations and other planning requirements such as reasonable further progress and contingency measures submitted by California. We continue to believe that section 193 ratifies our long

- standing practice of allowing credit for California's waiver measures notwithstanding the fact they are not approved into the SIP, and correctly reflects Congressional intent to provide California with the broadest possi ble discretion in the development and promulgation of on

- road and nonroad vehicle and engine standards. Further, even without considering section 193, the Act’s structure, evolution, and provision for the waiver of federal preemption for California mobile source emissions standards all support the EPA’s long

- standing interpretation of the CAA to allow California to rely on emission reductions resulting from waiver measures when developing SIP emission inventories, related attainment demonstrations, and cont ingency measures, even though the waiver measures are not in the SIP itself. Comment 10 : Referencing the District’s commitments to monitor, assess, and report on program implementation and to remedy emission reduction shortfalls, Earthjustice characterizes the “contingency measure” as an “enforceable commitment to adopt measures as needed” and asserts that such “committal SIPs” have repeatedly been rejected by the courts. More fundamentally, Earthjustice argues, “this commitment does not create enforceable emission limits or control

measures as required by section 110(a)(2)(A)” but rather “creates an enforceable duty to adoptThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

40 such emission limits or control measures as contingency measures” (emphases in original). Earthjustice contends that this is a plain v iolation of section 110(a)(2)(A). Moreover, Earthjustice contends, “this duty already exists under section 172(c)(9), so this proposed contingency measure adds nothing beyond what is already required by law.” Response 10 : We disagree with the commenter’s c haracterization of the District’s commitments in the Contingency Measure SIP as a “committal SIP.” Courts have rejected the EPA ’s use of the “conditional approva l” procedure in CAA section 110(k)(4) to permit states to postpone statutory SIP deadlines by s ubmitting “committal SIPs” that contain no specific remedial measures but instead merely promise to adopt such measures in the future. See, e.g. , Natural Resources Defense Council, Inc. v. EPA, et al, 22 F.3d 1125 (D.C. Cir. 1994) and Sierra Club v. EPA, 3 56 F.3d 296 (D.C. Cir. 2004). The District’s commitments in the Contingency Measure SIP, however, are not promises to adopt measures in the future. Instead, these SIP commitments identify on

- going emission reductions and current obligations that the Distri ct must satisfy on an ongoing basis. 22 Specifically, the District’s SIP commitments obligate the District to track its ongoing implementation of the Prop 1B and Carl Moyer Program requirements for specific projects relied upon for SIP credit and to submit r eports to the EPA, on an annual basis, that include detailed information regarding the type, location, and duration of each such project

22 As we explained in our proposed rule (78 FR 53113 , 53115), contingency measures may include Federal, state and local measures already scheduled for implementation that provide emission reductions in excess of those needed to provide for RFP or expeditious attainment. Nothing in the statute precludes a state from implementing such measures before they are triggered. See, e.g., LEAN v. EPA , 382 F.3d 575 (5th Cir. 2004) (upholding contingency measures that were previously required and implement ed where they were in excess of the attainment demonstration and RFP SIP). The EPA believes that its interpretation of the contingency measure requirement in section 172(c)(9) of the Act is reasonable because reductions from these contingency measures are continuing in nature.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

41 Section 4.5). As explained in supporting materials submitted by the District, all of the projects relied upon for SIP credit in the Contingency Measure SIP are subject to “already

- executed, legally binding contracts” which ensure that the District’s claimed emission reductions are currently being achieved. See SJVUAPCD, “Quantification of Contingency Reductions for the
2008 PM2.5 Plan ” (June 20, 2013) at 7, 8. Although the District’s SIP commitments include an enforceable requirement to submit substitute measures in the event of a shortfall in expected emission reductions for 2015, this secondary obligation does not hing to undermine the District’s

current obligation to m onitor, assess, and report on its implementation of the Prop 1B and Carl Moyer Program for the identified projects and the actual emission reductions achieved through these projects, consistent with the applicable requirements of Rule 9610. To the contrary , the secondary commitment to adopt and submit substitute measures is provided as a n additional safeguard to ensure that, if the projects relied upon for SIP credit fail to achieve the expected emission reductions by the applicable implementation deadline ( i.e. , by December 5, 2015), the District will be required to implement a timely remedy, i.e. , to adopt and submit substitute measures that achieve equivalent amounts of emission reductions by the same implementation deadline. 23 In sum, the District’s SIP c ommitments establish current obligations as part of an enforceable sequence of actions leading to compliance with a December 5, 2015 emission reduction obligation, which the EPA or citizens may enforce under the CAA. See Response 13. We also disagree with the commenter’s characterization of the District’s SIP commitments as

a “duty to adopt” emission limits or control measures that violates the requirements of CAA section 110(a)(2)(A)

. ” CAA section 110(a)(2)(A); see also CAA section 172(c)(6) (establishing substantively identical requirements for nonattainment areas ). Thus, in addition to “emission limitations” and “control measures,” the Act allows for SIPs to be built upon other “mea ns or techniques” as may be necessary or appropriate to provide for timely attainment of the NAAQS. See BCCA Appeal Group v. EPA , 355 F.3d 817 (5th Cir. 2003), reh’g denied , 2004 U.S. App. LEXIS 215 (5th Cir., January 8, 2004) ( noting expansion of the EPA’s authority under section 110(a)(2)(A) following Congress’ addition of the “means” and “techniques” and “as appropriate” language as part of the 1990 CAA Amendments ) . Moreover, as explained in the EPA’s proposed rule, both CAA section 110(a)(2)(A) and section 172(c)(6) explicitly provide for the use of economic incentives as one tool for states to use to achieve attainment of the NAAQS. See 78 FR 53113 , 53118 (quoting reference in CAA section 110(a)(2)(A) to “economic incentives such a s fees, marketable permits, and auctions of emissions rights”). Nothing in the Act prohibits the District’s use of economic incentives as part of a contingency measure plan that ensures an appropriate level of emission reduction progress if attainment is n ot achieved and additional planning by the State is needed. The incentive programs relied upon in the Contingency Measure SIP provide emission reductions in excess of those relied on for RFP or for expeditious attainment in the SJV PM 2.5 SIP ( 78 FR 53113 , 53123 ) . These incentive programs do not alter any existing control requirement in the applicable SIP and do not interfere with any applicable requirement concerning attainment and RFP or any other applicable requirement of the Act.

43 and Carl Moyer Program guidelines through a sequence of actions leading to compliance with a December 2015 emission reduction obligation, which the EPA or citizens may enf orce under
CAA sections 113 and 304, respectively. See Response 13. For all of these reasons, we conclude that the District’s SIP commitments are both enforceable “emission standards or limitations” a s defined in CAA section 304(f) 24 and appropriate “means or techniques” for achieving NO x and
PM 2.5 emission reductions under CAA sections 110(a)(2)(A) and 172(c)(6), and that these enforceable commitments are permissible components of a plan submitted to satisfy the attainment contingency measure requirement in CAA section 172(c)(9). Comment 11 : Earthjustice asserts that the EPA ’s reliance on the “enforceable commitment” to adopt control measures as an enforceable contingency measure is also a plain violation of section 172(c)(9), which requires that contingency measures “take effect . . . without further action by the State or the Administrator.” Citing the EPA ’s interpretive statements in the Addendum (59
FR 41998, August 16, 1994), Earthjustice contends that “[t]he commitment to adopt new rules
and measures is a blatant attempt to allow the District to defer adoption of enforceable contingency measures until after the attainment failure occurs” and that “[t]his undermines the entire purpose of the contingency measure requirement.” Earthjustice conclu des that the incentive program contingency measure therefore cannot be approved. Response 11 : We disagree. As explained in Response 10 above, the District’s SIP commitments
contain both a current obligation for the District to monitor, assess, and report on its ongoing implementation of the Prop 1B and Carl Moyer Program requirements with respect to specified projects and a secondary obligation for the District to implement a timely remedy, should the identified projects fail to achieve the expected emissi on reductions. These SIP obligations take

44 effect without further action by the State or the Administrator, in accordance with CAA section 172(c)(9). Additionally, consistent with the EPA’s longstanding interpretation of the contingency measure requirement in CAA section 172(c)(9) as requiring that all actions needed to effect full implementation of contingency measures occur within 60 days after the EPA notifies the State of a failure to attain the NAAQS by the applicable attainment date, 25 the District’s S IP commitments ensure that all actions needed to effect full implementation of the incentive

- based emission reductions will occur no later than December 5, 2015. Should the EPA find based on the 2014 annual demonstration report that the required amounts of NO x and PM 2.5 emission reductions may not continue through 2015 as projected, the EPA will promptly notify the District of its potential obligation to implement substitute measures consistent with its Board commitment no later than December 5, 2015, so th at the District has ample time for any rulemakings that may be necessary to meet this implementation deadline. Subsequently, should the EPA determine that the SJV area has failed to attain the 1997 PM 2.5 NAAQS by the applicable attainment date of April 5, 2015, 26 the District will be obligated under its SIP commitment either to confirm that the Prop 1B and Carl Moyer Program projects identified in the 2014 and 2015 annual demonstration reports will continue to achieve the required amounts of
NO x and PM 2.5 em ission reductions in December 2015 as projected, or to adopt and submit

- 42015 (“EP A generally expects all actions needed to effect full implementation of the [contingency] measures to occur within 60 days after EPA notifies the State of the area’s failure [to attain]”). 26 Under CAA section 179(c), the EPA must determine whether the SJV area has attained the 1997 PM 2.5 NAAQS “as expeditiously as practicable” and no later than 6 months after the applicable attainment date, based on the area’s air quality as of the attainment date . Because the applicable attainment date for the 1997 PM 2.5 NAAQS in the SJV area is April 5, 2015, the EPA must make this determination regarding attainment for the SJV no later than October 5, 2015.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

45 substitute measures achieving equivalent amounts of emission reductions (4.15 tpd of NO x reductions and 0.10 tpd of direct PM 2.5 reductions) no later than December 5, 2015. 27 See SJVUAP CD Board Resolution No. 13

- 6

- 18 at p. 3. Earthjustice suggests that only those “substitute” measures that the District would be obligated to implement in the event of an emission reduction shortfall constitute enforceable contingency measures, and that th e EPA’s approval of this SIP commitment therefore impermissibly allows the District to delay adoption of required measures. As discussed above, however, the enforceable contingency measure here is the District’s SIP commitment in its entirety, which includ es a current obligation to monitor, assess, and report on the District’s ongoing implementation of the Prop 1B and Carl Moyer Program requirements with respect to specified projects which collectively are expected to achieve 4.15 tpd of NO x reductions and 0.10 tpd of direct PM 2.5 reductions in 2015. This current obligation constitutes an enforceable measure in itself, and should the District fail to fully account for the required amounts of NO x and direct
PM 2.5 emission reductions in annual demonstration re ports submitted in 2014 and 2015 that

27 See n. 46, infra (discussing December 5, 2015 deadline for implementation of substitute measures under District ’s SIP commitment). In our proposed rule, we erroneously stated that following an EPA finding that the SJV area has failed to attain the 1997 PM 2.5 NAAQS, the District would be obligated to verify through the 2016 annual demonstration report whether the re quired amounts of NO x and direct PM 2.5 reductions had occurred or to adopt and submit substitute rules consistent with its Board commitment ( 78 FR 53113 , 53122 ) . We hereby clarify that the 2014 annual demonstration report (not the 2016 report) is the vehic le through which the District must either demonstrate that the required amounts of emission reductions will continue through 2015 or identify substitute measures to be implemented by December 5, 2015. See Rule 9610, Section 4.4 (requiring that each annual demonstration report “identify and quantify SIP commitment shortfalls, if any, and remedies for addressing said shortfalls”). We note, however, that under Rule 9610 the District remains subject to an ongoing obligation to retrospectively assess the perform ance of its incentive programs for potential future enhancements and that the 2016 annual demonstration report should, therefore, contain information adequate to verify whether the required amounts of NO x and direct PM 2.5 reductions occurred in 2015.

46 satisfy the applicable requirements of Rule 9610, the EPA may make a finding of failure to implement the SIP under CAA section 179(a) and either the EPA or citizens may take enforcement action under CAA section 113 or 304, respectively. See Response 12 and Response 13. The secondary obligation to adopt and submit “substitute” measures is an additional safeguard to be effectuated only if the District fails to satisfy its current obligation to monitor,

asse ss, and report on its ongoing emission reduction responsibilities. We therefore disagree with the commenter’s assertion that the District’s SIP commitment allows it to “defer adoption of enforceable contingency measures until after the attainment failure o ccurs.” In sum, the District’s SIP commitments establish current obligations on the District to take action well before the applicable attainment date to achieve the required emission reductions by December 5, 2015, whether through annual demonstration re ports submitted in 2014 and 2015 or through adoption and submission of substitute measures to be implemented by December 5, 2015. Given the District’s long history of successful implementation and enforcement of Prop 1B and Carl Moyer Program grants and th e detailed requirements in the associated incentive program guidelines, as discussed in our technical support document for the proposed rule ( see U.S. EPA Region 9, “Technical Support Document, Proposed Approval of Clean Air Act Section 172(c)(9) Contingen cy Measures, San Joaquin Valley State Implementation Plan for Attainment of the 1997 PM 2.5 Standards,” August 15, 2013 (hereafter “ Proposal TSD ”)) and further in these responses to comments, we expect that the District’s implementation of these program
req uirements for the identified projects will achieve the District’s claimed 4.15 tpd of NO x reductions and 0.10 tpd of direct PM 2.5 reductions in 2015. However, should the EPA find based on documentation submitted by the District in 2014 that the required em ission reductions may not occur in 2015 as projected, the District will be obligated under its SIP commitment to adoptThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

47 and submit substitute measures achieving the required emission reductions by December 5, 2015. We find these SIP commitments adequate to ensure that an appropriate level of emission reduction progress will continue to be made should the SJV area fail to attain the 1997 PM 2.5 NAAQS by the applicable attainment date of April 5, 2015. Comment 12 : Earthjustic e asserts that the incentive

- based emission reductions a re unenforceable by the EPA or citizens and that the EPA itself has described such emission reductions as “not enforceable against individual sources,” “voluntary,” and subject to a cap on SIP credit. Response 12 : We disagree with the commenter’s assertion that these emission reductions are unacceptable because they are unenforceable by the EPA or citizens. As the commenter notes, the EPA has described “voluntary” measures as those that are not directly enforceable against individual sources and has recommended presumptive limits (sometimes referred to as “caps”) on the credit that may be allowed in a SIP for such measures. Such voluntary measures may be credited for SIP purposes only where the State submits other en forceable mechanisms to ensure that the required emission reductions are achieved, subject to EPA and citizen enforcement under the CAA. As discussed further below, the incentive

- based emission reductions relied upon in the Contingency Measure SIP fall wit hin the EPA ’s presumptive limits on credit for voluntary
measures and are consistent with the EPA ’s recommendations for voluntary mobile source emission reduction programs. Additionally, these incentive

- based emission reductions are consistent with the EPA ’s recommendations for discretionary economic incentive programs. We discuss below EPA’s guidance on both voluntary measures and economic incentive programs (EIPs) and our rationale for concluding that the Contingency Measure SIP adequately addresses the a pplicable requirements of the Act, as described in these guidance documents.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

48 The EPA believes that it is appropriate and consistent with the Act to allow a limited percentage of the total emission reductions needed to satisfy any statutory requirement to c ome from “voluntary” or “emerging” measures or other nontraditional measures and programs , where the State commits to certain safeguards and satisfies the statutory criteria for SIP approval. See,
e.g. , “ Guidance on Incorporating Voluntary Mobile Source Em ission Reduction Programs in State Implementation Plans (SIPs),” October 24, 1997 (hereafter “1997 VMEP”) at 4

- 7; “Incorporating Emerging and Voluntary Measures in a State Implementation Plan,” September
2004 (hereafter “2004 Emerging and Voluntary Measure s Policy ”) at 8

- 12; and “Guidance on Incorporating Bundled Measures in a State Implementation Plan,” August 16, 2005 (hereafter “2005 Bundled Measures Guidance”) at 7

- 12. The EPA has described “ v oluntary measures” as measures or strategies that are not dir ectly enforceable against individual sources, and “emerging measures” as those that are more difficult to accurately quantify than traditional SIP emission reduction measures. 28 See 1997 VMEP at 4; 2004 Emerging and Voluntary Measures Policy at 13, 19; and 2005 Bundled Measures Guidance at 2. “V oluntary ” measures for stationary and area
sources may include consumer

- oriented programs to reduce the use of high

- emitting paints or other consumer products during the ozone season; mechanisms to encourage pollution prevention or process changes at unregulated emission points; and voluntary wood stove changeout program s. See 2004 Emerging and Voluntary Measures Policy at 19, 20

28 A measure can be both emerging and voluntary.

49 transportation management programs to manage employee commute and travel behavior ; area wide rideshare incentives to encourage commuters to use alternatives to single

- occupant vehicles ; and auto restricted zones, no

- drive days, or other limitations on veh icle use in a given geographic area

. See 1997 VMEP at Attachment 1. “Emerging” measures include activities that indirectly reduce emissions by promoting more efficient energy use or that promote renewable resources ( e.g. , use of solar power, wind power, or biomass) and activities that improve air quality by means other than emission reductions ( e.g. , heat island measures that reduce criteria pollutant concentrations by lowering ambient temperatures). See 2004 Emerging and Voluntary Measures Policy at 14

- 15. Where a State submits a VMEP or other voluntary or emerging measure for SIP approval, the EPA evaluates it for consistency with four fundamental “integrity elements” and with SIP attainment and reasonable further progress (RFP) requirements, and to

ensure that it does not interfere with other requirements of the Act. See 1997 VMEP at 6; see also 78 FR 53113 , 53118 and Proposal TSD at 22

- 24. In light of the increasing incremental cost associated with further stationary and mobile

source emission reduction s and the difficulty of identifying such additional sources of emission reduction s, the EPA encourages innovative approaches to generating emission reduction s through voluntary and emerging measures and other nontraditional measures and programs. See 1997 VMEP at 4

- 5; 2004 Emerging and Voluntary Measures Policy at 9; and 2005 Bundled Measures Guidance at 7

. The EPA also recognizes, however, that these nontraditional measures raise novel issues related to enforceability and quantification of the associated e mission reductions. Accordingly, the EPA ’s policies addressing nontraditional measures provide for some flexibility in meeting established SIP requirements for enforceability and quantification, provided the State takes clear responsibility for ensuring th at the emission reduction s necessaryThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

- 7; 2004 Emerging and Voluntary Measures Policy at 9; 2005 Bundled Measures Guidance at 7; and “Roadmap for Incorporating Energy Efficiency/Renewable E nergy Policies and Programs into State and Tribal Implementation Plans,” July 2012 (hereafter “2012 Roadmap for EE/RE Programs”) at 37

- 38. Importantly, the EPA has consistently stated that any voluntary or other nontraditional measure submitted for SIP cre dit must be accompanied by an appropriate enforceable “backstop” commitment from the State to monitor emission reductions achieved and to rectify any shortfall in a timely manner. See, e.g. , 1997 VMEP at 4

- 5; 2004 Emerging and Voluntary Measures Policy at 8

- 12; 2005 Bundled Measures Guidance at 7

- 12; and “Guidance on SIP Credits for
Emission Reductions from Electric

- Sector Energy Efficiency and Renewable Energy Measures,” August 5, 2004 (hereafter “2004 Electric

- Sector EE/RE Guidance”) at 6

- 7. Thus, althoug h the State is not necessarily responsible for implementing a program dependent on voluntary actions, the State is obligated to monitor, assess and report on the implementation of any such program and the associated emission reductions, and to remedy emiss ion reduction shortfalls in a timely manner should the voluntary measure not achieve the projected emission reductions. See 1997
VMEP at 6

- 7. The EPA believes that voluntary measures, in conjunction with the enforceable commitment to monitor emission reduc tions achieved and rectify any shortfall, meet the SIP control measure requirements of the Act. See 1997 VMEP at 5 and 2004 Emerging and Voluntary Measures Policy at 8

- 9. Given the innovative nature of these nontraditional measures, the EPA has recommended “presumptive” limits on the amounts of emission reductions from such measures that may be credited in a SIP. Specifically, for VMEPs , the EPA has identified a presumptive limit of three percent (3%) of the total projected future year emission reduction s r equired to attain theThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

51 appropriate NAAQS, and for any particular SIP submittal to demonstrate attainment or maintenance of the NAAQS or progress toward attainment (RFP), 3% of the specific statutory requirement. See 1997 VMEP at 5. As explained in the 2001 EIP Guidance, the EPA recommended this 3% cap (per pollutant) on the credit allowed for VMEPs because states are “not required to play a direct role in implementing these programs, the programs are not directly enforceable against participating parties, an d there may [be] less experience in quantifying the emission benefits from these programs.” 2001 EIP Guidance at 158. For voluntary stationary and

area source measures, the EPA has identified a presumptive limit of 6% of the total amount of emission reduct ions required for RFP, attainment, or maintenance demonstration purposes. See 2004 Emerging and Voluntary Measures Policy at 9 and 2005 Bundled Measures Guidance at 8. These limits are presumptive in that the EPA may approve emission reductions from voluntary or other nontraditional measures in excess of the presumptive limits where the State provides a clear and convincing justification for such higher amounts, which the EPA would review on a

case - by

- case basis. See id. The incentive

- based emission reductions in the Contingency Measure SIP are consistent with the EPA ’s recommendations in the 1997 VMEP. First, the Contingency Measure SIP and related support documents contain the State’s and District’s demonstration s that the claimed incentive

based emission reductions are quantifiable, surplus, enforceable and permanent consistent with
EPA policy. See Proposal TSD at 29

- 42. Second, the SIP submission contains enforceable commitments by the District to monitor, asses s and report on its implementation of specified portions of the Carl Moyer and Prop 1B programs and the associated emission reductions, and to remedy emission reduction shortfalls in a timely manner should these programs fail to achieve the projected amoun ts ( i.e. , 4.15 tpd of NO x reductions and 0.10 tpd of direct PM 2.5 reductions)This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

- 44. These commitments become federally enforceable by the EPA under CAA section 113 30 and by citizens under CAA sectio n 304 31 upon the EPA ’s approval of the commitments into the SIP. Thus, although neither the EPA nor citizens can enforce these emission reductions directly against sources, as a result of today’s action the EPA and citizens may enforce these emission reduct ions against the District, 32 pursuant to the District’s SIP

53 percent of the total projected PM 2.5 reductions needed to attain the 1997 PM 2.5 NAAQS in the San Joaquin Valley by April 5, 2015 ( 78 FR 53113 , 53121, n. 29 )

. These amounts of emission reductions fall within the EPA ’s recommended 3% cap (per pollutant) on the credit allowed for
VMEPs. Finally, the incentive

- based emission reductions do not interfere with requirements of the CAA and are consistent with the attainment and RFP requirements in the approved SJV
PM 2.5 SIP ( 78 FR 53113 , 53123 (discussing the EPA ’s evaluation of the Contingency Measure SIP in accordance with CAA section 110(l)). Additionally, as explained in our proposed rule, the EPA evaluated the incentive

- based emission reductions in the Contingency Measure SIP in accordance with the Agency’s guidance

on discretionary economic incentive programs (EIPs) 33 , specifically “financial mechanism EIPs ” ( 78 FR 53113 , 53118 , Augu st 28, 2013). The EPA ’s approach to discretionary EIPs differs in
several respects from its approach to “voluntary” and “emerging” measures. A discretionary EIP uses market

- based strategies to encourage the reduction of emissions from stationary, area, and /or mobile sources in an efficient manner. See 2001 EIP Guidance at 3. To qualify for approval as a discretionary EIP, emission reductions or actions leading to reductions must be enforceable either by the State or by the EPA , and the State must be directl y responsible for ensuring that program elements are implemented. See id. at 157

- 158 (states may use the 2001 EIP Guidance where “[a]ctions and/or emission reductions by identifiable sources are enforceable by [the State] and/or by the EPA ”). Additionally , the emission reductions resulting

33 T he EPA has promulgated regulations for “statutory EIPs” required under CAA sections 182(g), 187(d)(3), or 187(g) and has issued guidance for “discretionary EIPs.” See generally 40 CFR part 51, subpart U; 59 FR 16690 (April 7, 1994); and 2001 EIP Guidance. A “discretionary EIP” is any EIP submitted to the EPA as an implementation plan revision for purposes other than to comply with the statutory requirements of CAA sections 182(g)(3), 182(g)(5), 187(d)(3), or 187(g) ( 40 CFR 51.491 ) . In today’s action, we add ress only the requirements that apply to discretionary EIPs as the Contingency Measure SIP does not contain any statutory EIP.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

54 from an EIP must be quantifiable with a higher degree of certainty than the reductions resulting from an emerging measure. See 2004 Emerging and Voluntary Measures Policy at 5. Given these more rigorous approval criteria, the EPA ’s presumptive limits on SIP credit for voluntary and emerging measures do not apply to discretionary EIPs. See 2001 EIP Guidance at 158 (“[states] may use the EIP guidance to implement programs which wil l generate emission reductions beyond the 3 percent limit”); see also 2004 Emerging and Voluntary Measures Policy at 6 (“EIP measures are not subject to a percentage limitation that applies to voluntary measures”). A “financial mechanism EIP” is a n EIP th at indirectly reduces emissions by increasing costs for high emitting activities

– e.g. , through subsidies targeted at promoting pollution

- reducing activities or products. See 2001 EIP Guidance at 119

- 122 (Chapter 8.0). The EPA has identified

s everal attri butes that may make subsidy financial mechanism EIPs successful, including: (1) the relevant governmental body possesses legal authority to provide subsidies; (2) the subsidies address activities reasonably related to actual emissions or potential emission s; (3) where projected emission reductions are based on changes in behavior, methods for verifying that such reductions have taken place to the degree projected are generally accepted as unbiased and trustworthy; and (4) if needed, adequate penalty provisi ons are in place to ensure that the subsidy is used as expected. See 2001 EIP Guidance at 27 (“Attributes That Make Subsidy Financial Mechanism EIPs Successful”). As explained further below, the incentive

- based emission reductions in the Contingency
Measu re SIP are consistent with the EPA ’s recommendations for “financial mechanism EIPs” in the 2001 EIP Guidance. First, CARB and the District are directly responsible for ensuring that the Prop 1B program and Carl Moyer Program are implemented in accordance w ith State law.

. Second , t hese incentive funds address activities reasonably related to actual or potential air pollutant emissions by r equiring grant recipients to purchase and operate newer, cleaner vehicles or equipment in place of older, more

- polluting vehicles or equipment, subject to detailed contract requirements. See Response 13. Third, t he 2008 and 2010 Prop 1B guidelines and the 2011 Carl Moyer Program Guidelines establish a number of methods for verifying that projected emission reductions have taken place through compliance with the terms and conditions of each funding contract. See Response 13 and Response 14. Finally , under th e applicable guidelines, actions by grantees that lead to emission reductions are directly enforceable by the State and/or the District

– e.g. , CARB and/or the District may assess fiscal penalties and take certain corrective actions where contract violatio ns are identified 34

-- and EPA and citizens may, in turn, enforce the annual reporting and emission reduction obligation s against the District. See Response 13 and Response 14. Consistent with the EPA ’s recommendations for “financial mechanisms EIPs,” these provisions in the 2008 and 2010 Prop 1B guidelines and the 2011 Carl Moyer Program Guidelines are adequate to ensure that program funds are used as expected

– i.e. , to reduce emissions from higher

34 These State and District enforcement authorities distinguish both the Prop 1B program and the Carl Moyer Program from an entire ly “voluntary” measure, which depends on actions by individual sources that cannot be enforced. See, e.g., 2001 EIP Guidance at 157

- based emission reductions are characterized as dependent upon “voluntary” measures ( i.e., a VMEP) or resulting from a discretionary “financial mechanism EIP,” we find the District’s SIP commitments in the Contingency Measur e SIP adequate to ensure that the EPA and citizens may enforce these emission reductions under the Act

. The Contingency Measure SIP and related support documents also adequately address all other applicable requirements of the CAA and the EPA ’s recommendat ions as set forth in the 1997 VMEP and 2001 EIP Guidance ( 78 FR 53113 , 53118

- 53122 , August 28, 2013). Given all of these considerations, we find that the incentive

- based emission reductions in the Contingency Measure SIP satisfy the statutory criteria for SIP approval. Comment 13 : Citing both the 2001 EIP Guidance and the 2004 Emerging and Voluntary Measures Policy, Earthjustice highlights seven criteria for enforceability and asserts that the emission reductions identified in the Contingency Measure SIP d o not meet these criteria. Response 13 : As an initial matter, we note that both the 2001 EIP Guidance and the 2004 Emerging and Voluntary Measures Policy set forth the EPA ’s recommendations for EIPs or voluntary measures submitted for SIP purposes and do not establish binding legal requirements.

Based on this evaluation, we disagree with the commenter’s assertion that the incentive

based emission reductions in the Contingency Measure SIP fail to adequately address the enforceability recommendations provided in EPA policy. As the commenter notes, the 2001 EIP Guidance identifies enforceability considerations that are substantively identical to the recommendations in the 2004 Emerging and Voluntary Measures Policy

. A ccording to the 2001 EIP Guidance, emission reductions use, generation, and other required actions are enforceable if: (1) they are independently verifiable; (2) program violations are defined; (3) those liable for violations can be identified; (4) the Sta te and the EPA maintain the ability to apply penalties and secure appropriate corrective actions where applicable; (5) citizens have access to all the emissions

- related information obtained from the source; (6) citizens can file suits against sources for v iolations; and (7) they are practicably enforceable in accordance with other EPA guidance on practicable enforceability. See 2001 EIP Guidance at 35

Second, the applicable portions of the 2008 and 2010 Prop 1B guidelines and the 2011 Carl Moyer Program guidelines specifically define the required elements of each contract and the types of actions that constitute violations of su ch contracts. For example, under the 2008 and 2010 Prop 1B guidelines, each equipment project contract must include: (1) a unique “tracking number”; (2) the equipment owner’s contact information; (3) the original application submitted by the equipment owne r; (4) requirements for the equipment owner to submit reports to the local agency annually or biennially 38 ; (5) the equipment owner’s agreement to allow ongoing evaluations and audits of equipment and documentation by the District, CARB, or their designated representative(s); and (6) requirements for the equipment owner to retain all records pertaining to the program (i.e., invoices, contracts, and correspondence) for at least two years after equipment project ends or three years after final payment, whichev er is later.

See 2008 Prop 1B guidelines at Appendix A (“Trucks Serving Ports and Intermodal Rail Yards”), Section D (“Annual Reporting Requirements”). The 2010 Prop 1B guidelines also require annual reports except that certain owners of equipment with PM retrofits with a 2

62 that each contract “specify that by executing the contract, the grantee understands and agrees to operate the vehicle, equipment, and/or engine according to the terms of the contract” and describe the potential repercussions to the grantee for non

- compliance with contract requirements. See 2011 Carl Moyer Program Guidelines, Part I, Chapter 3 at Section Z.11 (“Re percussions for Non

- Performance”) and Section FF (“Nonperforming Projects”). 39 The 2011 Carl Moyer Program Guidelines also specifically identify types of actions on the part of the District that CARB may treat as violations of program requirements

– e.g. , m isuse of Carl Moyer Program funds and insufficient, incomplete, or inaccurate project documentation. See 2011 Carl Moyer Program Guidelines at Section U (“Program Non

- Performance”). Third, grantees that are liable for violations of these contract provision s can be identified by the State and/or District and, through the annual demonstration reports submitted to the EPA , by the EPA and citizens as well. Specifically, as discussed above, under the 2008 Prop 1B guidelines, the 2010 Prop 1B guidelines, and the 2011 Carl Moyer Program guidelines, each contract executed by the District must require the grantee to maintain project records for at least two years after contract expiration or three years after final project payment, whichever is later, and to submit a nnual or biennial reports to the District. See 2008 Prop 1B guidelines at Section III.D.10 (“Equipment project contracts”), 2010 Prop 1B guidelines at Section IV.A.11 (“Equipment project contracts”) 40 , and 2011 Carl Moyer Program Guidelines, Part I, Chapter 3 at Section Z (“Minimum Contract Requirements”); see also Proposal TSD at 30

- 40.

39 The 2011 Carl Moyer Program Guidelines authorize the District to grant a “waiver” to a grantee who demonstrates to the District’s satisfaction that certain conditions justify contract noncompliance for a define d period. See 2011 Carl Moyer Program Guidelines, Part I, Chapter 3 at Section FF.4(D). We note that, for any project that the District has relied upon for SIP credit, Section 4.3 of Rule 9610 requires the District to annually adjust its calculation of SIP

- creditable emission reductions to reflect periods of noncompliance under any such waiver. 40 See also n. 38, supra.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

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

63 Additionally, the 2008 and 2010 Prop 1B guidelines require that each contract contain a provision stating the equipment owner’s agreement to allow ongoing evaluations and audits of equipment and documentation by the District, CARB, or their designated repr esentative(s), and the 2011 Carl Moyer Program Guidelines similarly require that all contracts authorize the District, CARB, or their designees to conduct fiscal audits of the project and/or to inspect the project engine, vehicle, and/or equipment and asso ciated records during the contract term. See id. These provisions in the Prop 1B and Carl Moyer Program guidelines enable both the State and District to identify grantees that violate their contract provisions. The EPA and citizens, in turn, can identify violators through the annual demonstration reports that the District is obligated under its SIP commitment to make publicly available (on the District’s website) and to submit to the EPA by August 31 of each year.

- 19 (June 20, 2013) at 3 and Rule 9610, Section 5.0. Specifically, Section 6.1 of Rule 9610 (as adopted June 2013) 41 states that “[a]ll documents created and/or used in implementing the requirements of Section 4.0 shall be kept and maintained as required by the applicable incentive program guidelines. . . [and] shall be made available for public review” consistent with the California Public Records Act and other related requirements. Section 6.1 also states that “[i]nformation regarding the process for the publi c review of such records shall be included in the annual demonstration report.” Rule 9610, Section 6.1. Consistent with these requirements, the 2013 Annual Demonstration Report submitted by the District states that the public may request documents created and/or used in implementing the requirements of Section 4.0 (of Rule 9610) through the District’s Public Records Release Request form, which is available on the District website.

The District has confirmed that both the EPA and citizens may use this form to request copies of the required records for any Prop 1B or Carl Moyer Program project that the District has relied upon for SIP credit, which will be identified in the District’s an nual demonstration reports going forward. See e - mail dated December 18, 2013, from Jeannine Tackett, SJVUAPCD, to Idalia Perez, U.S. EPA Region 9, “RE: question needed for response to comments on contingency measure SIP.” 42 Fourth, the State maintains the a bility to apply penalties and secure appropriate corrective actions where contract terms are violated, and the EPA maintains the ability to require appropriate corrective actions of the District where projected emission reductions are not achieved. For exa mple, under the 2008 and 2010 Prop 1B guidelines, where the District finds that a grantee has violated a contract term, the District is authorized to recover all or a portion of program funds, assess fiscal penalties on equipment owners based on the severi ty of the non

performance, and prohibit the equipment owner from participating in future State incentive programs, among other things. See 2008 Prop 1B guidelines at Section IV.G (“Equipment

- mail, the Dis trict confirmed that it “will include information in future annual demonstration reports as necessary to ensure the ongoing tracking of projects claimed in prior annual demonstration reports, including adjustments necessary under Section 4.3 [of Rule 9610] .” We note that beginning with the 2014 annual demonstration report, the District must identify the specific projects (by unique project identification number) that the District has relied upon for emission reduction credit in the Contingency Measure SIP, including adjustments made as required by Section 4.3 of Rule 9610, to ensure that the EPA and citizens can track the District’s progress in satisfying its SIP commitments. See Rule 9610, Section 4.5; see also Proposal TSD at 27, n. 17. The District may sa tisfy this requirement by including, in its annual demonstration report, the list of specific projects in the attachments to the EPA’s Proposal TSD (as adjusted consistent with Rule 9610, Section 4.3), which the EPA developed because the 2013 Annual Demons tration Report does not specifically identify the projects relied upon for credit in the Contingency Measure SIP.

Under the 2011 Carl Moyer Program Guidelines, both CARB and the District are authorized to “seek any remedies available under the law for noncompliance with Carl Moyer Program requirements and nonperformance with the contract,” including withholding of program funds, and should CARB determine that the District’s oversight and enforcement of the program is insufficient, CARB may recapture funds granted to the District that have not yet been awarded to approved proj ects. See 2011 Carl Moyer Program Guidelines, Chapter 3 at Section U (“Program Non

- Performance”). Additionally, as explained further below, the EPA maintains the ability to enforce the District’s SIP commitments

– i.e. , to require the District to submit annual demonstration reports consistent with the requirements of Rule 9610 and/or to adopt and submit substitute measures on a fixed timeframe , where projected emission reductions are not achieved. Fifth, citizens have access to all of the emissions

source. As explained in our proposed rule, the Board commitments submitted with the Contingency Measure SIP obligate the District to “account for” its claimed NO x and PM 2.5 emission reductions “in annual demonstration repor ts pursuant to the requirements of Rule 9610.” See SJVUAPCD Board Resolution No. 13

66 requires that “[a]ll documents created and/or used in implementing the requir ements of Section 4.0 shall be kept and maintained as required by the applicable incentive program guidelines” and that “such records shall be made available for public review.” Rule 9610, Section 6.1. Under the 2008 and 2010 Prop 1B guidelines, all grant recipients must, among other things, retain “all documents, invoices, and correspondence associated with the application, award, contract, monitoring, enforcement, and reporting requirements” for at least two years after the equipment project contract term or three years after final payment, whichever is later”; must make records readily available and accessible to the District, CARB, or their designees upon request; and must submit regular reports to the District that include information about annual miles traveled, certification and documentation of travel within California’s trade corridors, and certification that the project was operated in accordance with the signed contract. See 2008 Prop 1B guidelines, Appendix A (“Trucks Serving Ports and Intermodal Rail Yards”), Section C (“Recordkeeping Requirements”) and Section D (“Annual Reporting Requirements”) at A

- 4 and 2010 Prop 1B guidelines, Appendix A (“Heavy Duty Diesel Trucks”), Section F (“Recordkeeping Requirements”) and Section G (“Annual Reporting Re quirements”) at A

67 Sixth, although citizens cannot file suits against sources for violations, both the EP A and citizens may file suits against the District for violations of its commitments to ensure that the projected emission reductions are achieved in 2015. Specifically, the SJVUAPCD Governing Board has submitted a commitment to quantify SIP

- creditable emi ssion reductions in the amount of 4.15 tpd of NO x reductions and 0.10 tpd of PM 2.5 reductions using the incentive program guidelines and related documents identified in Rule 9610 and to “account for these NO x and
PM 2.5 emission reductions in annual demonstration reports pursuant to the requirements of Rule 9610” for purposes of satisfying the PM 2.5 contingency measure requirement for 2015. SJVUAPCD Board Resolution No. 13

- 6

- 18 at p. 3. Additionally, the Board’s commitme nt states that “[if] there is a shortfall in expected emission reduction s for 2015, the District will adopt and submit to EPA substitute rules and measures that will achieve equivalent emission reductions as expeditiously as practicable and no later than a ny applicable implementation deadline in the
CAA or EPA ’s implementing regulations, by no later than December 31, 2016.” Id. As explained in our proposed rule (78 FR 53113 , 53121), t he EPA interprets these District commitments as applying to emission reduc tions to be achieved in 2015 through specific types of Prop 1B and Carl Moyer Program projects, 44 and the EPA expects that the 2014 annual demonstration report

grant, or to send all records to ARB by the end date of the grant agreement. See 2010 Prop 1B guidelines, Chapter II, Section E.10.b (“General Program provisions”) . U nder the Carl Moyer Program Guidelines, the District must keep each “project file” for a minimum of two years after the end of the contract term or a minimum of three years after final payment, whichever is later. See 2011 Carl Moyer Program Guidelines, Chapter 3, Section V (“ARB Au dit of Air Districts”) at 3

- 25. A “project file” generally includes a copy of the application, a completed pre

- and post

inspection form, and the annual reports submitted by the grantee. See id. at Section X.6, Section AA.4, Sect ion BB.1.(G), and Section D D.3. 44 This interpretation is consistent with information in the District’s 2013 Annual Demonstration Report, which identifies “agricultural off

- road vehicle replacement projects funded through the Carl Moyer Program” and “on

- road vehicle replacement proje cts funded through the Prop 1B program” as the projects relied upon for contingency measure purposes. See 2013 Annual Demonstration Report at 26 (Table 5).This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

68 will then specify the individual projects relied upon to achieve these emission reductions, consi stent with the requirements of Rule 9610, Section 4.5. See Proposal TSD at 25

- 27, n. 13 and n. 17 (referencing Proposal TSD at Attachment A and Attachment B). These Board commitments, which become federally enforceable by the EPA and by citizens upon appro val into the SIP, 45 impose clear and specific requirements on the District to account for specific amounts of NO x and PM 2.5 emission reductions through annual demonstration reports that satisfy the requirements of Rule 9610 and, if the identified projects f ail to achieve the projected emission reductions in 2015, to adopt and submit to the EPA substitute measures that will achieve equivalent amounts of emission reductions as expeditiously as practicable and no later than December 5, 2015. 46 Should the EPA det ermine that the SJV area has failed to attain the

45 See notes 30 and 31, supra. 46 Consistent with the EPA’s longstanding interpretation of CAA section 172(c)(9) as requiring that all actions needed to effect full implementation of contingency measures occur within 60 days after the EPA notifies the State of a failure to attain the NAAQS by the applicable attainment date (78 FR 53113 , 53115), we interpre t the phrase “applicable implementation deadline” in the District’s SIP commitment to mean 60 days after October 5, 2015, which is the latest date by which the EPA must determine whether the SJV area has attained the 1997 PM 2.5 NAAQS pursuant to CAA sectio n 179(c). In our proposed rule, we stated that the District’s commitment obligated it to adopt and submit any substitute measures necessary to correct a shortfall in emission reductions “ no later than December 31, 2016 ” ( 78 FR 53113 , 53121, 53122 ) . In this final action, however, we are clarifying our interpreta ti on of the SIP commitment to mean that any substitute measures necessary to correct a shortfall in 2015 emission reductions must be adopted and submitted to the EPA no later than the applicable imple mentation deadline for these contingency measures under CAA section 172(c)(9), which is December 5, 2015. This interpretation is consistent with the text of the District’s SIP commitment, which states that in the event of a shortfall, the District will “ad opt and submit to EPA substitute rules and measures that will achieve equivalent emission reductions as expeditiously as practicable and no later than any applicable implementation deadline in the CAA or EPA’s implementing regulations, by no later than Dec ember 31, 2016.” See SJVUAPCD Board Resolution No. 13

- 6

- 18 at p. 3 (emphases added). As a practical matter, because a December 2015 deadline for implementation of the remedy requires the District to begin developing any necessary substitute measures well b efore that date, the EPA intends to determine by late 2014 (based on the District’s 2014 annual demonstration report and other available documentation) whether there will be any shortfall in projected emission reductions that triggers the District’s obliga tion to adopt and submit substitute measures.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

69 1997 PM 2.5 standards by the applicable attainment date (April 5, 2015), the EPA and citizens may enforce both components of the District’s SIP commitment under sections 113 and 304 of the CAA, respectively, as follows: (1) if the Board fail s to annually account for its claimed NO x and PM 2.5 emission reductions consistent with the requirements of Rule 9610, the EPA or citizens may enforce the District’s obligation to submit the required reports; and (2) if th e District’s 2014 annual demonstration report indicates that the specific projects identified therein will not achieve the District’s claimed amounts of NO x and PM 2.5 emission reductions (4.15 tpd of NO x reductions and 0.10 tpd of PM 2.5 reductions) in 2015 as projected, the EPA or citizens may enforce the District’s obligation to adopt and submit substitute measures that will achieve equivalent amounts of emission reductions by December 5, 2015

. We find these p rovisions adequate to ensure that the EPA and citizens may secure appropriate corrective actions where projected emissi on reductions are not achieved. Finally, the emission reductions to be achieved through the identified Prop 1B and Carl Moyer Program pro

jects are practicably enforceable consistent with EPA policy on enforceability requirements. T he EPA generally considers a requirement to be “practically enforceable” if it contains a clear statement as to applicability; specifies the standard that must be met; states compliance timeframes sufficient to meet the standard; specifies sufficient methods to determine compliance, including appropriate monitoring, record keeping and reporting provisions; and recognizes relevant enforcement consequences. See “Revi ew of State Implementation Plans and Revisions for Enforceability and Legal Sufficiency,” September 3, 1987 (“19 8 7 Potter M emo”) and “Guidance on Enforceability Requirements for Limiting Potential to Emit through SIP and Section 112 Rules and General Permi ts,” January 25, 1995 (“1995 PTE Policy”) at 5, 6.

70 in the Contingency Measure SIP are practicably enforceable on two levels. First, as explained above, the actions required of grantees und er the 2008 and 2010 Prop 1B guidelines and the 2011 Carl Moyer Program Guidelines are practicably enforceable by the State and District. Specifically, under the applicable portions of the Prop 1B and Carl Moyer Program guidelines ( see Proposal TSD at 29

- 4 2), each grant of incentive funds must be subject to contract provisions that clearly identify the funded equipment or vehicle; specify the actions required of the grantee; identify relevant compliance timeframes ( e.g. , a “project life”); specify sufficien t methods to determine the grantee’s compliance with contract provisions, including detailed monitoring, recordkeeping and reporting requirements; and identify potential enforcement consequences in cases of contract non

- compliance. Taken together, these pr ovisions of the 2008 and 2010 Prop 1B guidelines and the 2011 Carl Moyer Program Guidelines ensure that the actions required of grantees are practically enforceable consistent with EPA policy. Second, the actions required of the District under its SIP com mitment are practicably enforceable by the EPA and citizens. As discussed above, the District has submitted an enforceable commitment to account for specified amounts of NO x and direct PM 2.5 emission reductions through annual demonstration reports meeting the requirements of Rule 9610 and, should the projects identified in those reports 47 fail to achieve the specified reductions in 2015, to adopt and submit substitute measures achieving equiva lent amounts of reductions on a fixed schedule. This commitment clearly identifies the District as the responsible entity; specifies the requirement that must be met and the compliance timeframes ( i.e. , to account for specific amounts of incentive

- based NO x and PM 2.5 emission reductions or to adopt and submit substitute measures by fixed dates); and, through reference to the requirements of Rule 9610, specifies

7 1 sufficient methods to determine compliance ( i.e. , the requirements under Section 4.0 of Rule 9610 that each annual demonstration report must satisfy). Should the District fail to submit annual demonstration reports meeting the requirements of Rule 9610 that confirm that its claimed NO x and PM 2.5 emission reductions occurred in 2015 as projected , the E PA may make a finding of failure to implement the SIP under CAA section 179(a), which starts an 18

- month period for the State/District to correct the non

- implementation before mandatory sanctions are imposed. Additionally, the EPA or citizens may enforce t he District’s obligation to adopt and submit substitute measures that will achieve equivalent emission reductions no later than December 5, 2015

. Taking into account all of these provisions of the applicable incentive program guidelines and the District’s SIP commitment s , we find the incentive

- based emission reductions relied upon in the Contingency Measure SIP to be practically enforceable consistent with EPA policy. Comment 14 : Earthjustice asserts that the incentive

- based emission reductions are not ind ependently verifiable because the EPA and citizens can only rely on data submitted to or collected by the District. Additionally, Earthjustice contends that the EPA has no authority to inspect sources for compliance with the contracts between the District and the source, and that the EPA also lacks the ability to apply penalties or secure corrective actions against the sources. Finally, Earthjustice asserts that because the emission reductions are secured through contracts between the source and the Distric t, compliance with those agreements cannot be enforced by the public or the EPA , and that the District “has discretion to modify these contracts and redefine violations without any EPA or public oversight.” Response 14 : First, we disagree with the commenter’s claim that the incentive

- based emission reductions are not independently verifiable. Although enforcement of these emission reductionsThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

- related information maintained by the District, this do es not preclude independent verification of the emission reductions if sufficient safeguards are in place to ensure that the District will obtain and maintain adequate compliance

related records and make these records available to the EPA and the public. A s discussed above, the applicable incentive program guidelines (the 2008 and 2010 Prop 1B guidelines and the 2011 Carl Moyer Program Guidelines) require that the District maintain specific documentation of
pre - project and post

- project inspections for each funded project and that all grantees submit detailed compliance

- related documentation to the District on an annual or biennial basis. The District, in turn, is obligated under its SIP commitment to make these project records available to the EPA and to the public upon request

. See Response 13

. Furthermore, as a result of the EPA ’s approval of the District’s commitments into the SIP, the EPA may require under CAA section 114(a) that the District provide information necessary for the purpose of determining wh ether the District is in violation of these SIP commitments

– including all compliance

- related documentation that the District maintains in accordance with the applicable incentive program guidelines. See CAA section 114(a) ( authorizing the EPA to require submission of information from “any person” who may have information necessary for the purpose of determining whether a SIP requirement has been violated ) and section 302(e) (defining “person” to include a State or political subdivision thereof)

. We find t he monitoring, recordkeeping and reporting requirements of the applicable incentive program guidelines, together with the District’s enforceable SIP commitments, adequate to ensure that the incentive

- based emission reductions can be independently verified. Second, although the commenter correctly states that the EPA is not authorized to inspect sources for compliance with the ir funding contracts or to apply penalties or secure correctiveThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

73 actions against individual sources , we do not believe such authorities are necessary in order to enforce these emission reductions under the CAA. As discussed in Response 13 above, both the District and CARB are authorized to inspect sources for compliance with their funding contracts and to apply penalties or sec ure corrective actions against sources that violate their contracts. Rule 9610 requires the District to maintain records of all such inspections and enforcement actions ( see Rule 9610, Section 6.1), and under section 114(a) of the CAA , the EPA may require the District to provide these project

- related records for purposes of determining whether the District is in violation of its SIP commitment. Both the EPA and citizens may also obtain these records from the District through submission of a “Public Records Release Request.” See Response 13

. Based on these project

- related records, the EPA and citizens may verify whether the District has adequately accounted for 4.15 tpd of NO x reductions and 0.1 0 tpd of PM 2.5 reductions in 2015, consistent with its SIP commit ments. Additionally, where the documentation evidences a shortfall in the required emission reductions, the District would be obligated

– subject to the EPA and citizen enforcement under the CAA

– to adopt and submit substitute measures that achieve equiva lent emission reductions no later than December 5, 2015

. We find these provisions adequate to ensure that the incentive

- based emission reductions in the Contingency Measure SIP may be enforced under the CAA. Finally, although we agree with the commenter’s claim that neither the EPA nor citizens can enforce compliance with the contracts between sources and the District, we disagree with the claim that the District has discretion to “redefine violations without any EPA or public oversight.” As explained above, upon approval into the SIP the District’s commitments become federally enforceable by the EPA and by citizens under sections 113 and 304 of the Act, respectively. See Response 13

- comment rulemaking. See CAA section 110(l) ; 5 U.S.C. section 553; 40 CFR 51.105 ; see also Response 8

. Comment 15 : Earthjustice cites the EPA ’s 2001 EIP Guidance to support its assertion that to be enforceable, a “financial mechanism EIP” must meet the general programmatic and source

specific definitions of enforceable. Earthjustice asserts that the EPA ’s analysis does not include any review of the programmatic requirements outlined in EPA policy and that the Valley’s incentive program “violates several of these criteria.” Additionally, as to the “source

- specific” definition of enforceable in EPA policy, Earthjustice asserts that the EPA lacks t he ability to independently verify compliance because the EPA is reliant upon information collected by the State and District and cannot collect its own information, conduct inspections, demand additional reporting, or enforce the failure to submit require d reports. Earthjustice further contends that the limited reporting required under the Carl Moyer program does not allow the EPA to independently verify compliance given “EPA must rely on the limited documentation submitted by the owner and will not even s ee reports on usage of the new equipment unless that data happens to be collected by the State or District and shared with EPA.” Earthjustice concludes that the incentive program contingency measure thus fails to be “enforceable” either at the programmatic level or the source

- specific level. Response 15 : We disagree with Earthjustice’s characterization of the EPA ’s recommendations in the 2001 EIP Guidance. The EPA stated in the 2001 EIP Guidance that “[t[ he emission reductions associated with a financial me chanism EIP are enforceable if they meet the general programmatic and source

- specific definitions of enforceable.” 2001 EIP Guidance at 120. Additionally, the EPA sta ted that although a program containing these elements would assureThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

75 that the program would meet the applicable CAA provisions, the EPA would also evaluate programs submitted by states that do not contain all of these elements and would determine, through notice

- and

- comment rulemaking, whether such programs satisfied the applicable CAA requiremen ts. See 2001 EIP Guidance at 119 ; see also 2001 EIP Guidance at 12 and 19

. Because the enforceability considerations highlighted in the 2001 EIP Guidance are non

- binding recommendations, the EPA does not apply them as regulatory criteria in its evaluation of an EIP submission. We have, however, evaluated the incentive

- based emission reductions in the Contingency Measure SIP for consistency with the EPA’s recommendations in the 2001 EIP Guidance and find them generally consistent with the general programmati c and source

- specific definitions of “enforceable ” in this document. As Earthjustice notes, the “programmatic” definition of enforceable highlights seven key factors that should be considered in determining whether an EIP is enforceable. See 2001 EIP Guidance at 35

- 36. We addressed each of these seven factors in Response 13 above. The “source

- specific” definition of enforceable highlights three key factors that should be considered in determining whether an EIP is enforceable : (1) t he source is liable for any violations; (2) the liable party is identifiable; and (3) the State, the public, and the EPA can independently verify a source’s compliance. See 2001 EIP Guidance at 40. With respect to the first two factors (the source’s liability for violations a nd the ability to identify the liable party), see Response 13 above. With respect to the third factor (the ability of the State, the public, and the EPA to independently verify a source’s compliance), see Response 14 above. We also disagree with Earthjusti ce’s assertion that the EPA cannot collect the information necessary to independently verify compliance and that the reporting required under the Carl Moyer program does not allow the EPA to independently verify compliance.

. Comment 16 : The District notes that the EPA did not review emission reductions achieved through the National Resource s Conservation Service Environmental Quality Incentives Program (NRCS EQIP) for the replacement of agricultural equipment (as included in Rule 9610 and documented through the District’s 2013 Annual Demonstration Report ). It describes efforts that have been taken toward developing procedures for crediting these emission reductions for SIP purposes including the statement of principles agreed upon by the District, NRCS, EPA, and CARB in December 2010 48 and the document signed by the EPA and NRCS in July 2012. 49 The District states that the agencies that signed these statements agreed to work collaboratively to develop a mechanism to provide SIP credit for emission reductions from federal, state, and local incentive programs that meet the EPA integrity principles of being surplus, quantifiable, enforceable, and permanent. The District comments that it appreciates the EPA’s efforts over the last several years in reviewing the NRCS EQIP Program in the context of these agreements and

78 Rule 9610 and looks forward to the EPA’s approval of this program as SIP

- creditable in the near future. Response 16 : We did not evaluate the EQIP as part of our action on the Contingency Measure SIP because the District did not specifically identify any emission reductions from the EQIP a s part of its contingency measure plan and because emission reductions from the Carl Moyer and Prop 1B projects identified in our proposed rule and the Proposal TSD provide sufficient emission reductions to meet the CAA contingency measure requirement for the 1997 PM 2.5 NAAQS in the SJV. See Contingency Measure SIP at 7

- 9 and 2013 Annual Demonstration Report at Table 5; see also Proposal TSD at 25

- 27, n. 13 and n. 17. Comments regarding the EQIP program are therefore outside the scope of this action. Commen t 17 : Citing the EPA’s discussion of voluntary and discretionary economic incentive programs in the proposed rule, the District states that the EPA has generally limited the amount of emission reduction credit allowed in a SIP for discretionary incentive p rograms to three percent of the total projected future year emission reductions required to attain the relevant NAAQS. The District states that “[t]his three percent cap does not affect this contingency measure demonstration and should be removed from the proposed rule, since EPA notes the amount of incentive

- based emission reductions used in this contingency demonstration is less than two percent of the total projected emission reductions needed to attain the 1997 PM 2.5 NAAQS in the Valley.” It further ass erts that “the District should not be limited to a three percent limit for incentive

- based reductions achieved through SIP

- creditable processes, such as Rule 9610.” In support of these assertions, the District quotes from the EPA’s stated rationale in
the 2001 EIP Guidance (at pg. 139) for the recommended 3 percent cap on SIP credit for voluntary programs and the EPA’s statement that states “may use the EIP guidance to implementThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

79 programs which will generate emission reductions beyond the 3 percent limit, or when [the state has] already reached the 3 percent limit under the voluntary measures guidance.” Finally, the District notes that the 2001 EIP Guidance sets forth only non

- binding policy and does not represent final EPA action on the requirements for EIPs

. Response 17: With respect to voluntary mobile source emission reduction programs (VMEPs), the EPA has generally limited the amount of emission reductions allowed in a SIP to three percent (3%) of the total projected future year emission reductions requir ed to attain the relevant NAAQS, and for any particular SIP submittal to demonstrate attainment or maintenance of the NAAQS or progress toward attainment (RFP), 3% of the specific statutory requirement. See 1997 VMEP at 5. Similarly, with respect to volunt ary and emerging measures for stationary

sources, the EPA has generally limited the amount of emission reductions allowed in a SIP to 6% of the total amount of emission reductions required for RFP, attainment, or maintenance demonstration purposes. See 200 4 Emerging and Voluntary Measures Policy at 9 and 2005 Bundled Measures Guidance at 8. These limits are “presumptive” in that the EPA may approve emission reductions from voluntary or other nontraditional measures in excess of the presumptive limits where the State provides a clear and convincing justification for such higher amounts, which the EPA would review on a case

- by

- case basis. See id.; see also Response 12

. It appears the District may have misunderstood the EPA’s intent in discussing this presumpt ive 3% limit on the emission reduction credit allowed in a SIP for VMEPs. In the proposed rule (78 FR 53113, 53118), we discussed the presumptive 3% limit both to provide context on the applicable EPA guidance to date and to indicate that the incentive

- bas ed emission reductions in the Contingency Measure SIP adequately address the EPA’s recommendations in the 1997 VMEP, a s applicable ( 78 FR 53113, 53118 and 53121 ) . Our proposed rule made clear,This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

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

80 however, that we were evaluating the Contingency Measure SIP in accordance with the fundamental integrity elements identified in several EPA guidance documents, as applied not only to VMEPs but also to discretionary “financial mechanism EIPs.” See id. at 53118 (citing both 2001 EIP Guidance and 1997 VMEP). Although we observed in the proposed rule that the
NO x and direct PM 2.5 emission reductions attributed to Carl Moyer Program and Prop 1B projects in the Contingency Measure SIP each amounted to less than 2 percent of the total projected emission reductions needed to attain the 1997 PM 2.5 NAAQS in the SJV (78 FR 53113 , 53121), this factual observation was intended to provide additional support for our proposal and was not a necessary basis for our action. See Response 12. Our discussion of the presumptive 3% limit provides relevant context on the EPA’s guidance on voluntary and incentive programs to date, and we disagree with the District’s statement that this discussion should be excluded from the analyses supporting our rulemaking action. We agree, however, with the District’s suggestion that it is not necessarily limited to a 3% cap on the amount of SIP emission reduction credit allowed for incentive programs. As the District correctly notes, the 2001 EIP Guidance sets forth only non

- binding policy and does not represent final EPA action on the requirements for EIPs. See 2001 EIP Guidance at 12. Likewise, the presumptive 3% limit on the SIP credit allowed for a VMEP under the 1997 VMEP policy is also a non

- binding policy recommendation. In addition, the 2001 EIP Guidance explicitly provides that states may use it to implement p rograms which will generate emission reductions beyond the 3 percent limit, provided the state is directly responsible for ensuring that program elements are implemented. See 2001 EIP Guidance at 139. The EPA will review each SIP submitted by California th at relies on emission reductions from incentive programs on a case

81 incentive programs for emission reductions exceeding the EPA’s presumptive caps, the EPA wil l determine through notice

- and

- comment rulemaking whether the State has provided adequate justification for such higher amounts and whether the submission, as a whole, satisfies the requirements of the Act. Because the incentive

- based emission reductions i n the Contingency Measure SIP fall below the EPA’s recommended 3% limit, we do not need to decide in today’s action whether the State has provided adequate justification for higher amounts of emission reduction credit. Comment 18 : The District disagrees in part with the EPA’s description of the effect of a “case

by

- case determination” under the Carl Moyer Program and with the EPA’s statement that such determinations give the State broad discretion without EPA oversight or public process. First, the District states that case

- by

- case determinations are defined under Rule 9610 as “alternative procedures approved by ARB for specific projects, as authorized under the Carl Moyer Program Guidelines” and that these are not limited to “determinations that provide for a longer project life.” Second, the District states that “all case

- by

- case determinations submitted for review to ARB are made available to the public via public web posting at ARB’s Carl Moyer Program website, and [that] the District is required by the C arl Moyer Program Guidelines to keep a copy of the determination in the project file.” Third, the District states that under Section 3.2.2 of Rule 9610, no case

- by

- case determination may be used to quantify emission reductions under the rule unless each de termination is reviewed through a public process and submitted to the EPA in accordance with Section 7.0. Finally, the District confirms the EPA’s understanding that emission reductions from projects subject to case

- by

- case determinations are not included in the 2013 Annual Demonstration Report but disagrees with the EPA’s statement in the proposed rule that such projects “are not eligible for SIP credit,” noting that the reason these are not included inThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

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

82 the 2013 Annual Demonstration Report is that they are “extremely rare and make up less than one percent of District administered incentive programs.” In conclusion, the District maintains
that case

- by

- case determinations made in accordance with Rule 9610 should be eligible for SIP credit. Response 18: We do not dispute the District’s statement that “case

- by

- case determinations” under the Carl Moyer Program are not limited to determinations that allow for a longer project life and note the broad definition of the term “case

- by

- case determination” in Section 2. 4 of Rule 9610. We discussed case

- by

- case determinations in the p roposed rule only to note that, although the portions of the three incentive program guidelines that we reviewed generally establish criteria consistent with the requirements of the Act, the provisions regarding case

- by

- case determinations in these portions of the guidelines do not adequately address the Act’s requirements for SIP emission reduction credit ( 78 FR 53113 , 53120 ) . We referenced, as an example, a provision in the 2011 Carl Moyer P rogram guideline entitled “Project Life” and noted that emission reductions from any project subject to a case

- by

- case determination under such a provision would not be eligible for SIP credit “unless the District submits the individual
determination for E PA review and approval through the SIP process” ( 78 FR 53113 , 53120 (referencing 2011 Carl Moyer Program guideline at Chapter 9, Section C.1(c)(5)). The purpose of this discussion was to make clear that the EPA is not, through this rulemaking, authorizing the District to rely on any project subject to a case

- by

- case determination under the referenced incentive program guidelines, nor is the EPA approving any such case

- by

- case determination. As the District correctly notes, Rule 9610 specifically prohibits the District from using a

case - by

- case determination to quantify emission reductions under the rule “unless such determination is reviewed through a public process and submitted to EPA in accordance withThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

83 Section 7.0.” Rule 9610, Section 3.2.2. Section 7.0 of the rule states, in relevant part, that “[e]ach SIP submission in which the District relies on [projections of SIP

- creditable emission reductions] shall contain a demonstration that the applicable incentive program guideline(s) continues to provide for SIP

- creditable emission reductions....” Read together, these provisions require the District to submit any case

- by

- case determination that it intends to rely on for SIP credit to the EPA in a formal SIP submission, together with a demonstration that the dete rmination and the project(s) subject to it provide for emission reductions that are surplus, quantifiable, enforceable, and permanent. See Rule 9610, Section 7.0 (establishing requirements for SIP submissions) and Section 2.25 (defining “SIP

- Creditable Emi ssion Reduction”). Upon the EPA’s approval of such a SIP consistent with CAA requirements, projects subject to the identified case

- by

- case determination would be eligible for SIP credit

. In sum, case

- by

- case determinations under the Carl Moyer Program are not currently eligible for SIP credit but may become eligible for credit through the EPA’s approval of SIP submissions going forward. Should the District intend to rely on emission reductions from a project subject to

a case - by

- case determination to satis fy a SIP requirement, it may do so only following its submission of the determination to the EPA as part of a SIP that meets the requirements of Rule 9610, Section 7.0 and the EPA’s approval of such SIP consistent with the requirements of the
CAA. The EPA appreciates the District’s statement confirming that projects subject to case

- by

- case determinations are not included in the 2013 Annual Demonstration Report and is approving the incentive

- based emission reductions in the Contingency Measure SIP based on o ur understanding that it does not rely on any case

- by

- case determination. C. General CommentsThis document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

84 Comment 19 : Earthjustice urges the EPA not to approve the San Joaquin Valley contingency measures for the San Joaquin Valley’s PM 2.5 SIP. Earthjustice argues that the Contingency
Measure SIP “ does not comply with the Clean Air Act and would leave Valley r e sidents without meaningful air quality protections if and when the Valley fail s to attain the 1997 PM 2.5 standards. ” Response 19 : F or the reasons discussed in our proposed rule and further explained in our responses to comments above, we have determined that the Contingency Measure SIP corrects the deficiency that prompted our partial disapproval of the SJV PM 2.5 SIP and strengthens t he SIP and are, therefore, approving it into the California SIP. We disagree with the claim that the approval of this Contingency Measure SIP would leave SJV residents “without meaningful air quality protections” should the SJV fail to meet the 1997
PM 2.5 standards by the applicable attainment date of April 5, 2015. The Contingency Measure SIP demonstrates that California has adopted measures that will achieve substantial emission reductions in and after 2015 that will provide significant on

- going air qual ity benefits to SJV residents. Specifically, the Contingency Measure SIP shows that in calendar year 2015, adopted and implemented federal and State mobile source control measures will reduce NO x emissions by 21 tpd; State and local incentive grant funds w ill reduce NO x emissions by an additional 4.15 tpd; and the SIP

- approved contingency provision in the District’s residential woodburning rule, Rule 4901, will provide 3.1 tpd of direct PM 2.5 reductions should we determine that the SJV has failed to attain the 1997 PM 2.5 standards by the applicable attainment date of April 5, 2015 ( 78 FR 53113 , 53123 )

85 SJV, these contingency measures will provide an additional 9 percent reduction in N O x emissions and an additional 5 percent reduction in direct PM 2.5 emissions in 2015. 50
Comment 20 : Earthjustice objects to the EPA’s statement that contingency measures must be implemented “quickly without significant additional ac tion by the state , ” stating that th e additi on of “significant” in 40 CFR 51.1012 was the result of a scrivener’s error and is not consistent with the plain statutory lan guage of CAA section 172(c)(9). Quoting from the preamble to the EPA’s
2007 PM 2.5 Implementation Rule, Eart hjustice notes that the EPA acknowledged this error in its adoption of the rule. Response 20 : We agree that the inclusi on of “significant” in 40 CFR 51.1012 was in error and note the correction. Comment 21 : Mr. Unger comments that the SJV area has not me t the PM 2.5 standards and that air quality has not improved much in the past few years. He also states that both the SJV’s citizens and the District are reluctant to do more to improve air quality. For these reasons, he urges the EPA to not approve the SIP for the 1997 annual and 24

- hour PM 2.5 standards. He disagrees with our statement that “the State has most likely done all it can to correct the deficiency” given the continuing nonattainment in the San Joaquin Valley. He states that if the EPA were to imp ose sanctions on the SJV, it would encourage California to adopt controls sufficient to attain the standards. He includes a list of suggested measures in his comments. Response 21 : In 2011, w e approved all but one element of California’s SIP to attain the 1997 annual and 24

- hour PM 2.5 standards in the SJV (76 FR 69896 , November 9, 2011). Our action here is to approve the last outstanding element of that SIP, the contingency measures for failure

86 to make RFP or attain. Our approval is based on our determinati on that the Contingency Measure SIP corrects the deficiency that prompted our 2011 disapproval of the contingency measure provisions in the SJV PM 2.5 SIP. Although the commenter asserts generally that SJV citizens and the District are “reluctant” to do mor e to improve air quality, that the SJV area has not complied with the NAAQS for many years, and that the threat of sanctions might encourage further regulatory action, the commenter fails to identify any specific basis under the CAA for disapproving the Co ntingency Measure SIP. The purpose of contingency measures is to continue progress in reducing emissions while the SIP is being revised to meet a missed RFP milestone or correct continuing nonattainment. Should the EPA determine that the SJV has failed to attain the 1997 standards by the applicable attainment date (April 5, 2015), the State and District will be required to implement these contingency measures and to revise the SIP to assure expeditious attainment consistent with applicable CAA requirements. We appreciate the list of control measures and will forward it to the District for its consideration during development of the next PM 2.5 SIP f or the Valley. III. Final Action s The EPA is approving the Contingency Measure SIP (adopted June 20, 2013 and submitted July 3, 2013 ) based on the Agency’s conclusion that this SIP submission corrects the deficienc y in the CAA section 172(c)(9) attainment contingency measure s that w as one of two bas e s for the EPA’s partial disapproval of the SJV PM 2.5 SIP on Novem ber 9, 2011 (76 FR 69896)

. The EPA also find s that the CAA section 172(c)(9) RFP contingency measure requirement for the 2012 RFP milestone year is moot as applied to the SJV nonattainment area because the

area has achieved its SIP

87 year. This finding correct s the d eficienc y in the CAA section 172(c)(9) RFP contingency

measure s that w as the second of two bas e s for the EPA’s partial disapproval of the SJV PM 2.5 SIP on November 9, 2011 (76 FR 69896)

. Finally, the EPA is approv ing enforceable commitments by the District to monitor, assess, and report on actual NO x and direct PM 2.5 emission reductions achieved through its implementation of specific Prop 1B and Carl Moyer Program grants and to re medy any identified emission reduction shortfall in a timely manner as found on page 3 of the SJVUPACD Governing Board Resolution No. 1 3

Today’s final actions li ft the CAA section 179(b)(2) offset sanctions and terminate the CAA section 179(b) (1) highway funding sanction clock triggered by the 2011 partial disapproval of the SJV PM 2.5 SIP . Th ese actions also terminate t he EPA’s obligation under CAA section 110(c)
to promulgate a corrective Federal implementation plan within two years of the partial disapproval

. IV. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410( k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA's role is to approve State choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely

a pproves State law as meeting Federal requirements and does not impose additional requirements beyond those imposed by State law. For th at reason, th is action:

 is 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);This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

Blumenfeld on April 28 , 2014

88  d o es not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

 is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act(5 U.S.C. 601 et seq. );

 d o es 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);

 d o es not have Federalism implications as specified in Executi ve Order 13132 (64 FR 43255, August 10, 1999);

 is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

 is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

 is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and

 d o es not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because it does not apply in Indian country located in the State, and the EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.This document is a prepublication version , signed by EPA Region 9 Regional Administrator, Jared

89 The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency prom ulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this action and other required information to the U.S

. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register . This action is not a “major rule” as defined by 5 U.S.C. 804(2). Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by [INSERT DATE 60 DAYS
AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]

. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judi cial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements ( see section 307(b)(2)). List of Subjects in 40 CFR Part 52
