Identification of Nonattainment Classification and Deadlines for Submission of 

State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM2.5) 

National Ambient Air Quality Standard (NAAQS) and 2006 PM2.5 NAAQS

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

SUMMARY: On January 4, 2013, in Natural Resources Defense Council (NRDC) v. 

EPA, the D.C. Circuit Court remanded to the EPA the “Final Clean Air Fine Particle 

Implementation Rule” (April 25, 2007) (the “2007 PM2.5 Implementation Rule”) and the

“Implementation of the New Source Review (NSR) Program for Particulate Matter Less 

than 2.5 Micrometers (PM2.5)” final rule (May 16, 2008) (the “2008 PM2.5 NSR Rule”). 

The Court found that the EPA erred in implementing the 1997 PM2.5 National Ambient 

Air Quality Standards (NAAQS) pursuant solely to the general implementation 

provisions of subpart 1 of Part D of Title I of the Clean Air Act (CAA or Act), without 

also considering the particulate matter-specific provisions of subpart 4 of Part D. The 

Court's ruling remanded the rules to the EPA to address implementation of the 1997 

PM2.5 NAAQS under subpart 4. This final rulemaking identifies the classification under 

subpart 4 for areas currently designated nonattainment for the 1997 and/or 2006 PM2.5

standards, the deadlines for states to submit attainment-related and nonattainment new 

source review (NNSR) state implementation plan (SIP) elements required for these areas 

pursuant to subpart 4, and the EPA guidance that is currently available regarding subpart 

4 requirements. The final deadlines for 1997 and 2006 PM2.5 NAAQS attainment-related 

SIP submissions and NNSR requirements for nonattainment areas would replace previous 

deadlines that were set solely pursuant to subpart 1. Specifically, the EPA is identifying

the initial classification of current 1997 and/or 2006 PM2.5 NAAQS nonattainment areas 

as “Moderate,” and the EPA is setting a deadline of December 31, 2014, for submission 

of remaining required SIP submissions for these areas, pursuant to and considering the 

application of subpart 4. This rulemaking affects 1997 and 2006 PM2.5 NAAQS 

nonattainment areas. After the careful consideration of the comments received on the 

proposal, the EPA is planning to finalize the rule as it was proposed. As part of the final 

rulemaking, the EPA is also updating 40 CFR part 81, “Designation of Areas for Air 

Quality Planning Purposes” for the 1997 and 2006 PM2.5 NAAQS nonattainment areas.

On January 4, 2013, in NRDC v. EPA, the D.C. Circuit Court remanded to the EPA 

the 2007 PM2.5 Implementation Rule and the 2008 PM2.5 NSR Rule. 706 F.3d 428 (D.C. 

Cir. 2013). Prior to the Court’s decision, and continuously since 2005, the EPA had 

implemented the 1997 and 2006 PM2.5 NAAQS pursuant to regulations and guidance1

that were based on the general implementation provisions of subpart 1. The Court found 

that the EPA erred in implementing the 1997 PM2.5 NAAQS solely pursuant to subpart 1, 

without consideration of the particulate matter-specific provisions of subpart 4. 

The subpart 4 requirements for areas classified as Moderate are generally 

comparable to those of subpart 1. The general provisions for requirements for all 

nonattainment areas for subpart 4 include: (1) section 189(a)(1)(A) (NNSR permit 

program); (2) section 189(a)(1)(B) (attainment demonstration or demonstration that 

attainment by the applicable attainment date is impracticable); (3) section 189(a)(1)(C) 

(reasonably available control measures (RACM) and reasonable available control 

technology (RACT)); (4) section 189(c) (reasonable further progress (RFP) and 

quantitative milestones); and (5) section 189(e) (precursor requirements for major 

stationary sources). Subpart 4 introduces additional statutory SIP planning requirements 

in the event that the EPA reclassifies a Moderate nonattainment area to a Serious 

nonattainment area and in the event the area needs extensions of time to attain the

NAAQS. The General Preamble and Addendum provide useful guidance on the specific 

subpart 4 statutory requirements.2

Following the January 2013 court decision, the EPA considered the implications of 

this decision on its implementation of the 1997 and 2006 PM2.5 standards and determined 

that it was important to clarify certain key issues. Accordingly, on November 21, 2013 

(78 FR 69806), the EPA published a notice of proposed rulemaking seeking comment on 

the EPA’s proposed identification of the classification under subpart 4 for areas currently 

designated nonattainment for these two standards, the deadlines for states to submit 

attainment-related and NNSR SIP elements required for these areas pursuant to subpart 4, 

and the EPA guidance that is currently available regarding subpart 4 requirements. In 

response to the notice of proposed rulemaking, the EPA received sixteen substantive 

comments. A summary of significant comments received and the EPA’s response is 

provided throughout this notice. To review the full Responses to Comment Document, 

see Docket ID No. EPA-HQ-OAR-2013-0694. 

In this final rulemaking, the EPA takes additional steps to respond to the court’s 

remand and to address the implementation of the 1997 and 2006 PM2.5 NAAQS under 

subpart 4. In light of the long history of implementation of these standards under subpart 

1, the EPA’s final rulemaking seeks to integrate and harmonize ongoing implementation

III. Initial Identification of “Moderate” Classification for PM2.5 Nonattainment 

Areas under Subpart 4

A. Summary of Proposal

Under the EPA’s prior approach to implementing the 1997 and 2006 PM2.5 

standards according to subpart 1, the EPA was not required to, and did not, identify any 

classifications for areas designated nonattainment. By contrast, subpart 4 of the CAA, 

section 188, provides that all areas designated nonattainment are initially classified “by 

operation of law” as “Moderate” nonattainment areas, and they remain classified as 

Moderate nonattainment areas unless and until the EPA later reclassifies them as Serious 

nonattainment areas or the EPA determines that an area has not attained the PM2.5

NAAQS by the area’s applicable attainment date. Therefore, the EPA proposed to 

identify all PM2.5 nonattainment areas as “Moderate.”

Two public interest groups commented that the classification of PM2.5

nonattainment areas as “Moderate” occurs by operation of law upon designation, and 

therefore this Moderate classification does not require any EPA action beyond the initial 

designation of an area as nonattainment.

The EPA agrees that the CAA provides that all areas designated nonattainment 

are initially classified as “Moderate.” However, as explained in the proposal, the NRDC

holding that the EPA erred in implementing the 1997 PM2.5 NAAQS solely pursuant to 

subpart 1 should not be applied retroactively. Nonattainment area designations for all 

areas became effective many years before the 2013 NRDC decision. See 70 FR 944, 

January 5, 2005; 74 FR 58688, November 13, 2009; 76 FR 6056, February 3, 2011. 

Subpart 1 contains no nondiscretionary provision for classification of nonattainment 

areas. Under the interpretation, which prevailed during years of implementation prior to 

the D.C. Circuit’s 2013 ruling, no classifications were identified or recognized, nor were 

subpart 4 classifications implemented. In accordance with the NRDC decision, and 

because the EPA has not previously identified nonattainment area classifications under 

subpart 4 for areas designated nonattainment for the 1997 and 2006 PM2.5 standards, the 

EPA has done so in this rulemaking to clarify the current classification of areas.

A public interest group also commented that this rulemaking should identify 

Libby, Montana, San Joaquin Valley, California, and the Los Angeles-South Coast Air 

Basin, California, as having failed to attain the 1997 PM2.5 standards by the subpart 4 

statutory attainment deadline and explain that the areas were reclassified by operation of 

law as Serious, as required by 42 U.S.C. section 7513(b)(2). The commenter further

claimed that Libby, Montana, San Joaquin Valley, California, and the Los Angeles-South 

Coast Air Basin, California, should be required to submit Serious area plans for the 1997 

PM2.5 standard that satisfy the subpart 4 requirements.

As explained in the proposal and previously in this section, the EPA believes that 

the D.C. Circuit Court’s 2013 holding in NRDC should not be applied retroactively. 

States with areas designated nonattainment for the 1997 PM2.5 standard had previously 

been instructed by the EPA, prior to the NRDC decision, to implement and attain the 

1997 PM2.5 standard according to the general implementation provisions of subpart 1 as 

provided in the EPA’s implementation rules. The EPA therefore disagrees that Libby, 

Montana, San Joaquin Valley, California, and the Los Angeles-South Coast Air Basin, 

California, were required to attain the 1997 PM2.5 standard no later than the statutory 

attainment date provided in subpart 4. As of that date, the EPA was implementing the 

1997 standard pursuant to subpart 1, and no court had ruled that the EPA or any state 

should implement the PM2.5 standard under the provisions of subpart 4. The EPA 

therefore disagrees that Libby, Montana, San Joaquin Valley, California, and the Los 

Angeles-South Coast Air Basin, California, were reclassified “by operation of law” as 

Serious no later than June 30, 2011, as the commenter contends. Because these areas are 

classified as Moderate, and not Serious, the affected states are required at this time to 

submit plans for these areas that satisfy CAA section 189(a) and not section 189(b)(1).

At some future time, the EPA may reclassify as Serious any nonattainment area 

that the EPA determines cannot practicably attain the PM2.5 NAAQS by the applicable 

attainment date. These areas may also be reclassified as Serious by operation of law if the

Administrator determines that any area has not in fact attained the PM2.5 NAAQS after 

each area’s applicable attainment date has passed.4

C. Final Action 

Pursuant to subpart 4 of the CAA, section 188, and section 301 of the CAA, the 

EPA in this notice is identifying the classification of all PM2.5 areas currently designated 

nonattainment for the 1997 and 2006 NAAQS as “Moderate.” Thus, the provisions of 

subpart 4 relevant to areas currently designated nonattainment for the 1997 and/or 2006 

PM2.5 NAAQS would initially be those applicable to Moderate areas. 

IV. Deadline for Submission of Remaining Required SIP Elements

A. Summary of Proposal

The EPA proposed to set a deadline of December 31, 2014, for the states to 

submit any additional attainment-related SIP elements that may be needed to meet the 

applicable requirements of subpart 4 for areas currently designated nonattainment for the 

1997 and/or 2006 PM2.5 NAAQS, and to submit SIPs addressing the NNSR requirements 

in subpart 4. The EPA proposed this date because the EPA believes that this period 

provides a relatively brief but reasonable amount of time for states to ascertain whether 

and to what extent any additional submissions are needed for a particular 1997 or 2006 

PM2.5 NAAQS nonattainment area, and to develop, adopt and submit any such SIPs.

 

4

In the General Preamble, the EPA has previously addressed the requirements of CAA 

section 188 concerning classifications under subpart 4, including the issue of 

discretionary and mandatory reclassification from Moderate to Serious. See 57 FR 13498, 

at 13537-8.

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

States with PM2.5 NAAQS nonattainment areas have already been working on needed 

submittals, and the EPA will continue working with them to ensure timely submissions.

B. Comments and Responses

Several public interest groups and individuals commented that the EPA does not

have authority to reset the deadlines and/or should not provide states until December 31, 

2014, to submit SIPs complying with subpart 4 requirements. These commenters believe 

that SIPs for the 1997 and 2006 PM2.5 standards are overdue. 

The EPA disagrees with the commenters. As stated in the proposal and previously 

in this notice, it is the EPA’s position that the NRDC decision does not apply 

retroactively, including to create an obligation in the past for states to submit 

implementation plans under subpart 4 demonstrating attainment of the PM2.5 NAAQS. 

Prior to the Court’s decision, the prevailing implementation rulemaking instructed states 

to submit plans solely under subpart 1. The D.C. Circuit Court did not vacate this rule. 

Nor did the Court compel the EPA to treat the deadlines for the obligations the Court 

announced in its decision as already having lapsed, and the states as if they had already 

failed to meet these obligations. Instead, the D.C. Circuit Court remanded the rules to the 

EPA for repromulgation under subpart 4. Thus, the NRDC decision directed that the EPA 

act prospectively to implement the PM2.5 NAAQS under subpart 4 through one or more 

national rulemakings consistent with the NRDC decision. This action is one such 

rulemaking. 

Because of the complexity of the CAA’s SIP provisions and the interrelationship 

between federal and state action, the EPA believes it is inappropriate to impose 
Page 14 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

retroactive effect on decisions in a manner that would create deadlines that have long 

passed. Courts have supported this position. For example, in Sierra Club v. Whitman, 285 

F.3d 63 (D.C. Cir. 2002), the D.C. Circuit Court of Appeals addressed an EPA failure to 

make a timely determination of failure to attain the applicable ozone NAAQS and to 

reclassify the St. Louis, Missouri area. Id. at 65. Reclassification would have resulted in 

requirements for the area to submit new attainment plans. Id. The D.C. Circuit Court

ruled that the EPA was required to make the determination, but expressly rejected the 

Sierra Club’s request to consider the area as reclassified as of the date that the EPA’s 

determination should have been made. Id. at 67-68. The D.C. Circuit Court refused to 

impose the statutory deadline for SIP submittals when that deadline had passed long 

before the court’s decision. Id. at 67-68. The D.C. Circuit Court noted that backdating the 

EPA’s determination would only make the situation worse by likely imposing large costs 

on the states for failing to develop SIPs years earlier even though the states were not on 

notice at the time of their obligation to do so. Id. at 68.

This rulemaking is not an extension of the deadline established by the EPA when 

it was implementing the PM2.5 standards according to subpart 1. Rather, this rulemaking 

makes that deadline no longer operative, since the EPA is no longer following only 

subpart 1 to implement the PM2.5 standards. Under the unique circumstances presented 

here, the EPA relies on its authority under section 301 of the CAA to establish a 

reasonable, and expeditious, deadline, of December 31, 2014, by which states must 

submit SIPs consistent with the subpart 4 requirements. 
Page 15 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

Several commenters suggested that the EPA should allow states more time to 

submit any remaining SIP planning requirements and NNSR SIP submissions required 

pursuant to subpart 4, and therefore the deadline for submissions should be later than 

December 31, 2014.

The EPA disagrees with the commenters. Subpart 4, section 188, provides that 

states are to submit required plans 18 months after an area is designated nonattainment. 

However, the NRDC case was not decided until years after areas were designated 

nonattainment under subpart 1 of the CAA. In light of the timing and substance of the 

D.C. Circuit Court’s opinion, the EPA believes that states should be provided a 

reasonable opportunity to submit any remaining SIP planning requirements and NNSR

SIP submissions required pursuant to subpart 4. The EPA believes that setting the 

deadline for such submissions as December 31, 2014, provides a relatively brief but 

reasonable amount of time for states to ascertain whether and to what extent any 

additional submissions are needed for a particular nonattainment area, and to develop, 

adopt, and submit any such plans. States with PM2.5 NAAQS nonattainment areas have 

already been working on needed submittals, and the EPA will continue working with 

them to ensure timely submissions. In determining a deadline, the EPA considered: the 

amount of time that has passed since the NRDC decision, when this rulemaking will be 

finalized, and the amount of time remaining before the 2006 PM2.5 NAAQS attainment 

deadline under subpart 4 for most areas of December 31, 2015.5 The EPA is balancing 

 

5 The EPA designation for the West Central Pinal area in Arizona as nonattainment for 

the 2006 PM2.5 NAAQS became effective March 7, 2011. See 76 FR 6056, February 3, 
Page 16 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014.

the desire to allow states a reasonable amount of time to develop SIP submissions that 

conform to subpart 4 requirements, while leaving enough time before the 2006 PM2.5

NAAQS attainment date so that state plans have time to be implemented and work. In 

consideration of all of these circumstances, the EPA believes December 31, 2014, is a 

reasonable deadline.

Several public interest groups and individuals commented that instead of allowing 

states until December 31, 2014, to submit SIPs for PM2.5 NAAQS, the EPA should 

immediately find that areas failed to submit a SIP.

The EPA disagrees with the commenters. States’ obligation to submit plans to the 

EPA demonstrating attainment of the 1997 and 2006 PM2.5 NAAQS was triggered by the 

EPA’s designation of the relevant areas as nonattainment. The EPA, consistent with its 

prior interpretation of the Act, implemented the PM2.5 standards according to, and 

instructed states to follow only the requirements of subpart 1. Subpart 1 requires states to 

submit SIPs to demonstrate attainment of the NAAQS by a date established by the EPA 

that is no later than three years after the date of designation of an area as nonattainment. 

42 U.S.C. section 7502(b). 

The EPA also explained in various rulemaking and guidance documents that SIPs 

would need to meet the requirements of section 172(c) of the CAA, which governs

submissions under subpart 1. Thus, states were not instructed to submit their PM2.5

NAAQS SIPs under the subpart 4 timeline, and they were not instructed to submit a 

 

2011. Therefore, the latest attainment date applicable to this area under subpart 4 is 

December 31, 2017.

PM2.5 NAAQS SIP to meet the requirements of subpart 4. Therefore, the prevailing 

regulatory regime continuously since 2005, and until the NRDC decision in 2013, 

required submission only of subpart 1 plan on or before deadlines established according 

to subpart 1. As a result, the EPA has no outstanding duty to find that states have failed to 

make subpart 4 submissions that had not previously been required of states and which 

were unknown to them at the time.

If the EPA were to give retroactive effect to the NRDC decision when the D.C. 

Circuit Court declined to do so, and impose past duties on states, the EPA would 

effectively penalize states that followed the EPA’s guidance and regulations to prepare 

SIPs in accordance with the timing and content of subpart 1. An EPA finding of failure to 

submit a SIP under subpart 4 that the commenter seeks would not give the states the 

opportunity to prepare or submit an appropriate SIP before being found in default of that 

obligation. 

Because the states had no notice of the timing or content of any alleged earlier 

subpart 4 submissions, the EPA believes that the Administrator does not have a 

nondiscretionary duty to find failures to submit subpart 4 SIPs, and it would be 

inappropriate to issue such a finding.

The EPA’s position on this issue has been recently upheld in federal court. In 

Wildearth Guardians v. McCarthy, 2014 U.S. Dist. LEXIS 31267, March 11, 2014 (D. 

Colo.), Wildearth Guardians claimed that states’ 2006 PM2.5 NAAQS SIPs should have 

been submitted according to the timeline laid out in subpart 4 of the CAA, which would 

have been no later than June 14, 2011. Because the states had made no SIP submission,

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

Wildearth Guardians claimed that the EPA was required to make a finding that states had 

failed to submit subpart 4 SIPs. The Court dismissed the claim and agreed with the EPA’s 

position that “the NRDC court intended its decision to be prospective in effect, rather 

than retroactive.” Id. at *9. The Court also agreed that “the States were entitled to rely on 

the [2007 PM2.5] Implementing Rule promulgated by the EPA in scheduling the pace 

with which they would proceed in developing their PM2.5 SIPs.” Id. at *10.

The EPA believes that its position is supported by further case law, as well. In 

Sierra Club v. EPA, 356 F.3d 296 (D.C. Cir. 2004), the Court addressed the EPA’s 

decision to reclassify Washington, D.C. from a Serious to Severe nonattainment area for 

ozone and declined to require the EPA to make the reclassification retroactive. Id. at 308. 

The reclassification had the effect of imposing additional obligations on Washington, 

D.C., for which the deadlines had already passed. Id. at 309. The D.C. Circuit Court

rejected the Sierra Club’s argument because it “would give the reclassification retroactive 

effect by holding the states in default of their submission obligations before the events 

necessary to trigger that obligation (reclassification) . . . occurred.” Id. at 309. Therefore, 

the Court declined to give the reclassification retroactive effect before any deadline had 

been announced, and where it would impose a SIP submission deadline that had already 

passed. Id. at 309-10. See also Sierra Club v. Whitman, 285 F.3d 63 (D.C. Cir. 2002).

To the extent that commenters are arguing that the EPA should determine that 

certain states failed to submit a subpart 1 plan by the previously established 

December 14, 2012 deadline, the EPA believes that this rulemaking removes the basis to 

do so. This rulemaking supersedes any other, previously established deadline for the 
Page 19 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

submission of PM2.5 NAAQS attainment or NNSR plans under subpart 1. In accordance 

with the Court’s decision in NRDC, any deadline established by the EPA while the 

agency was implementing the PM2.5 standards under subpart 1 is being superseded.

Several commenters asked that the EPA clarify which nonattainment areas are 

potentially affected by this rule. 

The EPA identified in the proposal areas that appear to be most affected by this 

rule. These include areas for which states have not submitted a SIP and/or for which EPA 

has not yet made a determination of attainment of the 1997 or 2006 PM2.5 NAAQS, 

and/or for which states have not yet submitted a request for redesignation to attainment 

for the PM2.5 NAAQS. 

It is not necessarily the case that no additional submissions under subpart 4 will 

be required of an area that has attained the PM2.5 NAAQS or for which the EPA has 

approved attainment plans. This final rulemaking does not affect any action that the EPA 

has previously taken under section 110(k) of the Act on a SIP for a PM2.5 NAAQS 

nonattainment area. However, this does not necessarily mean that areas for which the 

EPA has previously approved attainment demonstration or NNSR plans have met all 

requirements of the Act. States may need to submit additional SIP planning requirements 

and NNSR SIP elements for any area currently designated nonattainment to show that 

they meet all of the applicable requirements of subpart 4. 

The EPA would also like to clarify what the EPA considers to be the application 

of the rulemaking for areas that have submitted complete redesignation requests. First, as 

a general matter, pursuant to CAA section 175A(c), Part D requirements remain in effect 
Page 20 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

until the EPA approves a redesignation request and an area is redesignated to attainment. 

However, for purposes of evaluating whether a redesignation request is approvable and 

meets the requirements of CAA section 107(d)(3)(E)(ii) and (v), the EPA’s longstanding 

interpretation of section 107(d)(3)(E) of the CAA is that, as a threshold matter, the Part D 

provisions which are “applicable” and which must be approved in order for the EPA to 

redesignate an area include only those which came due prior to a state’s submittal of a 

complete redesignation request. 78 FR 20856, 20861. See also “Procedures for 

Processing Requests to Redesignate Areas to Attainment,” Memorandum from John 

Calcagni, Director, Air Quality Management Division, September 4, 1992; Sierra Club, 

375 F.3d 537. To the extent that implementation under subpart 4 would impose additional 

requirements for areas designated nonattainment, the EPA believes that those 

requirements are not “applicable” for the purposes of CAA section 107(d)(3)(E) in any 

area that has submitted a complete redesignation request prior to the due date for these 

requirements, and thus the EPA is not required to consider subpart 4 requirements with 

respect to areas that have submitted a complete redesignation request prior to 

December 31, 2014. Applicable requirements of the CAA that come due subsequent to 

the area’s submittal of a complete redesignation request remain applicable until a 

redesignation is approved, but are not required as a prerequisite to redesignation.

Whether, and to what extent, any additional submissions are needed for a

particular 1997 or 2006 PM2.5 NAAQS nonattainment area will depend upon the 

circumstances of each individual nonattainment area. Based on the most up-to-date status 

of SIP submissions and approved SIPs, the EPA will continue working with states on a 
Page 21 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

case-by-case basis to assist them in addressing subpart 4 requirements. For help with 

questions or further clarification, states should consult with their respective EPA regional 

offices.

C. Final Action 

Through this final rulemaking action, the EPA is setting a deadline of December 

31, 2014, for the states to submit any additional attainment-related SIP elements that may 

be needed to meet the applicable requirements of subpart 4 for areas currently designated 

nonattainment for the 1997 and/or 2006 PM2.5 NAAQS, and to submit SIPs addressing 

the NNSR requirements in subpart 4. The EPA believes that this period provides a 

relatively brief but reasonable amount of time for states to ascertain whether and to what 

extent any additional submissions are needed for a particular 1997 or 2006 PM2.5

nonattainment area,6and to develop, adopt and submit any such SIPs. Section 188(c)(1) 

of Subpart 4 establishes an attainment deadline of no later than the end of the sixth 

calendar year after designation as nonattainment. With respect to the 2006 24-hour PM2.5 

NAAQS, nonattainment area designations for most areas became effective in December 

2009 (74 FR 58688, November 13, 2009). Thus, these areas are subject to a Moderate 

 

6 The answers to these questions will depend upon the circumstances of each individual 

nonattainment area, including whether the area’s monitored air quality meets the 

standard, and whether the state has already made attainment-related and NNSR SIP 

submissions for the area. As the EPA has explained in its proposed rulemaking on 

Approval and Promulgation of Air Quality Implementation Plans; Indiana; Redesignation 

of the Indianapolis Area to Attainment of the 1997 Annual Standard for Fine Particulate 

Matter (78 FR 20856, April 8, 2013), it is also important to evaluate, for each area, the 

interrelationship of the two subparts, and whether the substance of subpart 1 and subpart 

4 provisions, should, for certain purposes, be considered equivalent. 
Page 22 of 429

area attainment deadline under subpart 4 of no later than December 31, 2015. A SIP 

submission deadline of December 31, 2014, for these areas will therefore ensure that 

there is at least a year between SIP submission and attainment deadlines.7 The December 

31, 2014 deadline would allow a brief but reasonable amount of time for the states to 

modify their SIPs in consideration of subpart 4 in keeping with the timeframe established 

by the existing subpart 4 attainment deadline. With respect to the 1997 annual PM2.5

NAAQS, although nonattainment area designations in most areas became effective more 

than 8 years ago (see 70 FR 944, January 5, 2005), the EPA is establishing for these areas 

the same subpart 4 SIP submission deadline that would apply for purposes of the 2006 

PM2.5 NAAQS (December 31, 2014), so that all states with PM2.5 nonattainment areas 

have a reasonable amount of time to develop any additional SIP elements that may be 

required under subpart 4 in response to the NRDC decision. Thus, for all PM2.5 

nonattainment areas, the states would be required to submit any remaining SIPs that are 

necessary to satisfy the requirements applicable to Moderate nonattainment areas under 

subpart 4 of the Act no later than December 31, 2014. 

 

7 The EPA designation for the West Central Pinal area in Arizona as nonattainment for 

the 2006 24-hour PM2.5 standard became effective March 7, 2011. See 76 FR 6056, 

February 3, 2011. Although the latest attainment date applicable to this area under 

subpart 4 is December 31, 2017 (2 years later than the December 31, 2015, attainment 

date that applies to areas designated nonattainment in 2009), the EPA is requiring 

Arizona to submit an attainment SIP meeting the requirements of subpart 4 for the 2006 

24-hour PM2.5 standard for this area by the same December 31, 2014, date that we are 

requiring for other nonattainment areas. The December 31, 2014, SIP submission date 

would supplant the March 7, 2014, date by which the state was previously required under 

subpart 1 to submit a PM2.5 attainment SIP for this area, and would provide a reasonable 

amount of additional time for the state to both develop the required subpart 4 SIP 

elements and implement its control strategy in advance of the applicable attainment date.

V. What guidance is currently available to states regarding subpart 4 requirements? 

A. Summary of Proposal

In the proposal, the EPA identified its longstanding general guidance that 

interprets the 1990 amendments to the CAA and made recommendations to states for 

meeting the statutory requirements for SIPs for nonattainment areas. See the General 

Preamble and the Addendum. The EPA also directed states to a series of recent 

rulemakings on Indianapolis and other areas, which provide helpful guidance. See, e.g., 

“Approval and Promulgation of Air Quality Implementation Plans; Indiana; 

Redesignation of the Indianapolis Area to Attainment of the 1997 Annual Standard for 

Fine Particulate Matter” (78 FR 20856, April 8, 2013 - proposal) (78 FR 41698, July 11, 

2013 - final).

B. Comments and Responses

Two states commented that more specific information is needed from the EPA 

regarding the requirements of subpart 4 for submissions for PM2.5 Moderate area SIPs. 

The CAA does not impose a requirement on the EPA to promulgate an 

implementation rule for any NAAQS. In the context of the unique circumstances 

presented here, the EPA seeks to respond in a timely way to the D.C. Circuit Court’s 

NRDC decision and to enable states similarly to respond to the Court’s decision that 

subpart 4 applies to implementation of PM2.5 NAAQS. Thus, the EPA’s purpose is to 

provide sufficient notice and information to enable the states to move forward in 

complying with the directive of the Court. This rulemaking is not intended to address all 

issues that would be germane to an implementation rule, but rather answer preliminary
Page 24 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

questions that arise in the shift in implementation solely under subpart 1 to also include

subpart 4. 

The EPA agrees that guidance to states is helpful to clarify requirements and to 

respond more comprehensively to the Court’s remand, but the EPA believes that this 

rulemaking, combined with the EPA’s longstanding general guidance interpreting the 

requirements of subpart 4 of the CAA, provides an adequate basis for states to develop 

Moderate area attainment plans and NNSR plans. In the General Preamble, the EPA 

discussed the relationship of subpart 1 and subpart 4 SIP requirements, and pointed out 

that subpart 1 requirements were to an extent “subsumed by, or integrally related to, the 

more specific” subpart 4 requirements. 57 FR at 13538. Moreover, subsequent to the 

NRDC decision, the EPA has issued rulemakings for individual areas in which the EPA 

has further elaborated on the relationship of subpart 1 and subpart 4 requirements in the 

context of making determinations of attainment for areas that have attained the 1997 

PM2.5 standard, approving requests to redesignate areas to attainment or approving an 

area’s attainment demonstration.

C. Final Response

The EPA did not propose, nor is EPA at this time taking final action on an 

implementation rule governing PM2.5 implementation under subpart 4. The EPA is 

currently developing a proposal for a new implementation rule that would apply to 

current and future PM2.5 NAAQS. The agency plans to propose that rule later this year. 

The proposal will address a range of implementation requirements that apply to PM2.5 

nonattainment areas under subparts 1 and 4. Until that implementation rule is finalized,

the EPA believes that the General Preamble, Addendum, and recent rulemakings on 
Page 26 of 429

This document is a prepublication version, signed by EPA Administrator, Gina McCarthy on 4/25/2014. 

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

Indianapolis and other areas8provide helpful guidance for states in ascertaining the 

impact of subpart 4 requirements on their ongoing efforts to meet the 1997 and 2006 

PM2.5 standards and the EPA will approve states’ submissions in accordance with those 

documents. For help with questions or further clarification, states should consult their 

respective EPA regional offices.

This action is not a "significant regulatory action" under the terms of Executive 

Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under 

Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011).

B. Paperwork Reduction Act

This action does not impose an information collection burden under the 

provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. Burden is defined at 5 

CFR 1320.3(b). This final rulemaking identifies the classification under subpart 4 for 

areas currently designated nonattainment for the 1997 and/or 2006 PM2.5 standards and 

the deadline for states to submit SIP elements for these areas that are required pursuant to 

subpart 4.

C. Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a 

regulatory flexibility analysis of any regulation subject to notice and comment 

rulemaking requirements under the Administrative Procedures Act or any other statute 

unless the agency certifies the rule will not have a significant economic impact on a 

substantial number of small entities. Small entities include small businesses, small 

organizations and small governmental jurisdictions.

For purposes of assessing the impacts of this rule on small entities, small entity is 

defined as: (1) a small business as defined in the Small Business Administration’s (SBA) 

regulations at 13 CFR 121.201;) (2) a small governmental jurisdiction that is a 

government of a city, county, town, school district or special district with a population of

less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is 

independently owned and operated and is not dominant in its field.

After considering the economic impacts of this final rule on small entities, I 

certify that this action will not have a significant economic impact on a substantial 

number of small entities. This final rule will not impose any requirements directly on 

small entities. Entities potentially affected directly by this final rulemaking include state, 

local and tribal governments and none of these governments are small governments. 

Other types of small entities are not directly subject to the requirements of this rule 

because this action only identifies the classification under subpart 4 for areas currently 

designated nonattainment for the 1997 and/or 2006 PM2.5 standards and the deadline for 

states to submit SIP elements for these areas that are required pursuant to subpart 4.

D. Unfunded Mandates Reform Act 

This action contains no federal mandate under the provisions of title II of the 

Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531-1538 for state, local 

and tribal governments, in the aggregate, or the private sector. This action imposes no 

enforceable duty on any state, local or tribal governments or the private sector. Therefore, 

this action is not subject to the requirements of section 202 and 205 of the UMRA.

This action is also not subject to the requirements of section 203 of the UMRA 

because it contains no regulatory requirements that might significantly or uniquely affect 

small governments. This final rulemaking identifies the classification under subpart 4 for 

areas currently designated nonattainment for the 1997 and/or 2006 PM2.5 standards and 
Page 29 of 429

the deadline for states to submit SIP elements for these areas that are required pursuant to 

subpart 4.

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have substantial 

direct effects on the states, on the relationship between the national government and the 

states, or on the distribution of power and responsibilities among the various levels of 

government, as specified in Executive Order 13132. The requirement to submit SIP 

revisions to meet the 1997 and 2006 PM 2.5 NAAQS requirements under subpart 4 is 

imposed by the CAA. This final rule interprets those requirements as they apply to the 

1997 and 2006 PM 2.5 NAAQS. Thus, Executive Order 13132 does not apply to this 

action.

F. Executive Order 13175: Consultation and Coordination with Indian Tribal 

Governments

This action does not have tribal implications, as specified in Executive Order 

13175 (65 FR 67249, November 9, 2000). It would not have a substantial direct effect on 

one or more Indian tribes, since no tribe has to develop an implementation plan under 

these regulatory revisions. Furthermore, these regulation revisions do not affect the 

relationship or distribution of power and responsibilities between the federal government 

and Indian tribes. The CAA and the Tribal Air Rule establish the relationship of the 

federal government and tribes in developing plans to attain the NAAQS, and these 

revisions to the regulations do nothing to modify that relationship. Thus, Executive Order 

13175 does not apply to this action.

G. Executive Order 13045: Protection of Children from Environmental Health and Safety 

Risks

The EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying only to 

those regulatory actions that concern health or safety risks, such that the analysis required 

under section 5-501 of the EO has the potential to influence the regulation. This action is 

not subject to EO 13045 because it does not establish an environmental standard intended 

to mitigate health or safety risks. This final rulemaking identifies the classification under 

subpart 4 for areas currently designated nonattainment for the 1997 and/or 2006 PM2.5

standards and the deadline for states to submit SIP elements for these areas that are 

required pursuant to subpart 4.

H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect 

Energy Supply, Distribution, or Use

This action is not subject to Executive Order 13211 (66 FR 28355 (May 22, 

2001)), because it is not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 

(NTTAA), Public Law No. 104-113, section 12(d) (15 U.S.C. 272 note) directs the EPA 

to use voluntary consensus standards in its regulatory activities unless to do so would be 

inconsistent with applicable law or otherwise impractical. Voluntary consensus standards

are technical standards (e.g., materials specifications, test methods, sampling procedures 

and business practices) that are developed or adopted by voluntary consensus standards

bodies. NTTAA directs the EPA to provide Congress, through OMB, explanations when 

the agency decides not to use available and applicable voluntary consensus standards.

This action does not involve technical standards. Therefore, the EPA is not 

considering the use of any voluntary consensus standards. 

J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority 

Populations and Low-Income Populations

Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal 

executive policy on environmental justice. Its main provision directs federal agencies, to 

the greatest extent practicable and permitted by law, to make environmental justice part 

of their mission by identifying and addressing, as appropriate, disproportionately high 

and adverse human health or environmental effects of their programs, policies and 

activities on minority populations and low-income populations in the United States. 

The EPA has determined that this action will not have disproportionately high and 

adverse human health or environmental effects on minority or low-income populations 

because it does not affect the level of protection provided to human health or the 

environment. This final rulemaking identifies the classification under subpart 4 for areas 

currently designated nonattainment for the 1997 and/or 2006 PM2.5 standards and the 

deadline for states to submit SIP elements for these areas that are required pursuant to 

subpart 4.

K. Congressional Review Act 

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 promulgating 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 U.S. The EPA will submit a report containing this rule and other required 

information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller 

General of the U.S. 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). This rule will be effective on [INSERT 

DATE 30 DAYS FROM DATE OF PUBLICATION IN THE FEDERAL 

REGISTER].

L. Judicial Review 

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 Third Circuit within 60 days 

from the date this action is published in the Federal Register. Filing a petition for 

reconsideration by the Administrator of this final action 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 judicial review must be filed, and shall not postpone the effectiveness of this 

action.
