SUPPLEMENTARY INFORMATION:

Background
On April 5, 2013, DDOE submitted a SIP revision request to EPA. This SIP revision request, if approved, would revise DC's currently approved nonattainment NSR program by amending Chapters 1 and 2 under Title 20 of DC Municipal Regulations (DCMR). Generally, the revisions incorporate provisions related to two Federal rulemaking actions: The 2002 ``Prevention of Significant Deterioration (PSD) and Nonattainment NSR (NSR): Baseline Emissions Determination, Actual-to-Future-Actual Methodology, Plantwide Applicability Limitations, Clean Units, Pollution Control Projects'' (2002 NSR Rules; 67 FR 80186); and the 2008 ``Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM2.5)'' (2008 NSR PM2.5 Rule; 73 FR 28321).
The 2002 NSR Reform rules made changes to five areas of the NSR programs. In summary, the 2002 Rules: (1) Provided a new method for determining baseline actual emissions; (2) adopted an actual-to-
projected-actual methodology for determining whether a major modification has occurred; (3) allowed major stationary sources to comply with a Plantwide Applicability Limit (PAL) to avoid having a significant emissions increase that triggers the requirements of the major NSR program; (4) provided a new applicability provision for emissions units that are designated clean units; and (5) excluded pollution control projects (PCPs) from the definition of ``physical change or change in the method of operation.'' On November 7, 2003, EPA published a notice of final action on its reconsideration of the 2002 NSR Reform Rules,\1\ which added a definition for ``replacement unit'' and clarified an issue regarding PALs. For additional information on the 2002 NSR Reform Rules, see EPA's December 31, 2002 final rulemaking action entitled: ``Prevention of Significant Deterioration (PSD) and Nonattainment NSR (NSR): Baseline Emissions Determination, Actual-to-
Future-Actual Methodology, Plantwide Applicability Limitations, Clean Units, Pollution Control Projects'' (67 FR 80186), the 2003 final reconsideration: ``Prevention of Significant Deterioration (PSD) and Non-Attainment New Source Review (NSR): Reconsideration'' (68 FR 63021), and http://www.epa.gov/nsr.

\1\ See, ``Prevention of Significant Deterioration (PSD) and Non-Attainment New Source Review (NSR): Reconsideration;'' (68 FR 63021).
---------------------------------------------------------------------------
After the 2002 NSR Reform Rules were finalized and effective (March 3, 2003), industry, state, and environmental petitioners challenged numerous aspects of the 2002 NSR Reform Rules, along with portions of EPA's 1980 NSR Rules (45 FR 52676, August 7, 1980). On June 24, 2005, the United States Court of Appeals for the District of Columbia (D.C. Circuit) issued a decision on the challenges to the 2002 NSR Reform Rules. New York v. United States, 413 F.3d 3 (New York I).
In summary, the D.C. Circuit vacated portions of the rules pertaining to clean units and PCPs, remanded a portion of the rules regarding recordkeeping and the term ``reasonable possibility'' found in 40 CFR 52.21(r)(6) and 40 CFR 51.166(r)(6), and either upheld or did not comment on the other provisions included as part of the 2002 NSR Reform Rules. On June 13, 2007 (72 FR 32526), EPA took final action to revise the 2002 NSR Reform Rules to remove from federal law all provisions pertaining to clean units and the PCP exemption that were vacated by the D.C. Circuit.
The 2008 NSR PM2.5 Rule (as well as the 2007 ``Final Clean Air Fine Particle Implementation Rule'' (2007 PM2.5 Implementation Rule)),\2\ was also the subject of litigation before the D.C. Circuit in Natural Resources Defense Council v. EPA.\3\ On January 4, 2013, the court remanded to EPA both the 2007 PM2.5 Implementation Rule and the 2008 NSR PM2.5 Rule. The court found that in both rules EPA erred in implementing the 1997 PM2.5 NAAQS solely pursuant to the general implementation provisions of subpart 1 of part D of title I of the CAA (subpart 1), rather than pursuant to the additional implementation provisions specific to particulate matter in subpart 4 of part D of title I (subpart 4).\4\ As a result, the court remanded both rules and instructed EPA ``to re-promulgate these rules pursuant to subpart 4 consistent with this opinion.'' Although the D.C. Circuit declined to establish a deadline for EPA's response, EPA intends to respond promptly to the court's remand and to promulgate new generally applicable implementation regulations for the PM2.5 NAAQS in accordance with the requirements of subpart 4. In the interim, however, states and EPA still need to proceed with implementation of the 1997 PM2.5 NAAQS in a timely and effective fashion in order to meet statutory obligations under the CAA and to assure the protection of public health intended by those NAAQS. In a June 2, 2014 final rulemaking entitled ``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; Final Rule,'' (79 FR 31566), EPA identified the classification under subpart 4 for areas currently designated nonattainment for the 1997 and 2006 PM2.5 NAAQS. That rulemaking also established a December 31, 2014 deadline for the submission of any additional attainment related SIP elements that may be needed to meet the applicable requirements of subpart 4.
---------------------------------------------------------------------------
\2\ 72 FR 20586 (April 25, 2007).
\3\ 706 F.3d 428 (D.C. Cir. 2013).
\4\ The court's opinion did not specifically address the point that implementation under subpart 4 requirements would still require consideration of subpart 1 requirements, to the extent that subpart 4 did not override subpart 1. EPA assumes that the court presumed that EPA would address this issue of potential overlap between subpart 1 and subpart 4 requirements in subsequent actions.
---------------------------------------------------------------------------
Additionally, the 2008 NSR PM2.5 final rule authorized states to adopt provisions in their nonattainment NSR rules that would allow major stationary sources and major modifications locating in areas designated nonattainment for PM2.5 to offset emissions increases of direct PM2.5 emissions or PM2.5 precursors with reductions of either direct PM2.5 emissions or PM2.5 precursors in accordance with offset ratios contained in the approved SIP for the applicable nonattainment area. The inclusion, in whole or in part, of the interpollutant offset provisions for PM2.5 is
Page 73510
discretionary on the part of the states. In the preamble to the 2008 final rule, EPA included preferred or presumptive offset ratios, applicable to specific PM2.5 precursors that states may adopt in conjunction with the new interpollutant offset provisions for PM2.5, and for which the state could rely on the EPA's technical work to demonstrate the adequacy of the ratios for use in any PM2.5 nonattainment area. Alternatively, the preamble indicated that states may adopt their own ratios, subject to the EPA's approval, that would have to be substantiated by modeling or other technical demonstrations of the net air quality benefit for ambient PM2.5 concentrations. The preferred ratios were subsequently the subject of a petition for reconsideration, which the Administrator granted. EPA continues to support the basic policy that sources may offset increases in emissions of direct PM2.5 or of any PM2.5 precursor in a PM2.5 nonattainment area with actual emissions reductions in direct PM2.5 or PM2.5 precursors in accordance with offset ratios as approved in the SIP for the applicable nonattainment area. However, we no longer consider the preferred ratios set forth in the preamble to the 2008 final rule for PM2.5 NSR implementation to be presumptively approvable. Instead, any ratio involving PM2.5 precursors adopted by the state for use in the interpollutant offset program for PM2.5 nonattainment areas must be accompanied by a technical demonstration that shows the net air quality benefits of such ratio for the PM2.5 nonattainment area in which it will be applied.
A Technical Support Document (TSD) is included in the docket for this action, and contains additional detail regarding the history and background of the Federal counterparts to the regulations included in DDOE's submittal, which will not be restated here.

Summary of SIP Revision
Generally, the revision submitted by DDOE involves amendments to sections 199.1 (Definitions and Abbreviations) and 200 (General Permit Requirements), repealing and replacing section 204 (Permit Requirements for Sources Affecting Non-attainment Areas), repealing section 206 (Notice and Comment Prior to Permit Issuance), adding sections 208 (General and Non-attainment Areas) and 210 (Notice and Comment Prior to Permit Issuance), and adding specific definitions to section 299 (Definitions and Abbreviations). Additionally, several non-substantive, clarifying and organizational revisions were submitted. Following is EPA's rationale for the proposed approval.
-
-
NSR Reform
DDOE has not adopted the full suite of NSR reform regulations, opting instead for a ``hybrid'' approach, tailored to the particular air quality challenges and source universe in DC. The vast majority of sources in DC are institutional (e.g. hospitals, universities). Because it focused on large industrial source categories, much of the analysis performed by EPA in support of the 2002 Reform Rules may not be applicable in DC. However, as EPA stated in the preamble of the 2002 NSR Rules: ``. . . state and local jurisdictions have significant freedom to customize their NSR programs. Ever since the current NSR regulations were adopted in 1980, we have taken the position that States may meet the requirements of part 51 `with different but equivalent regulations. 45 FR 52676.' Several States have, indeed, implemented programs that work every bit as well as our own base programs, yet depart substantially from the basic framework established in our rules . . .'' (See 67 FR 80241). Therefore, EPA is able to approve state SIP revisions that are at least as stringent as the Federal rules even if they contain provisions that differ. EPA's proposed approval in this case, therefore, hinges upon the determination that the proposed revisions are at least equivalent to the Federal program and do not constitute an impermissible backslide under the CAA.
-
Calculating Emissions Increases
In order for a physical change or change in the method of operation at a major stationary source to be considered a major modification and trigger NSR requirements, the net emissions increase resulting from the project at hand must exceed the significance threshold(s) for one or more pollutant. One of the primary components of the 2002 NSR Reform Rules was a change in the regulations governing how to quantify the emissions increase relative to the pre-project baseline. Federal regulations allow the use of ``baseline actual emissions'' (BAE) to determine a facility's emissions prior to the change. For a facility that is not an electric generating unit (EGU), BAE is calculated by selecting any 24-month period during the preceding ten years and computing the average emission rate. The ``look-back'' period for EGUs is five years. DDOE has not adopted the Federal regulations relating to the calculation of BAE; rather, DDOE has retained the pre-NSR reform definition of ``actual emissions.'' Actual emissions are calculated by averaging the emissions in the 24-month period immediately preceding the project at hand. The revisions to the definition of ``actual emissions'' submitted by DDOE do not substantively change the look-back period for calculating actual emissions. Rather, they clarify that DDOE may allow the use of a different time period within the last five years if a demonstration can be made that it is more representative of the facility's operations. Additionally, the revisions require that the same 24-month period be used for all pollutants. These proposed revisions differ from the Federal regulations which allow different 24-
month periods to be used for different pollutants.
Once the baseline has been established, it is necessary to calculate the increase resulting from the project relative to that baseline. Federal regulations allow a source to use ``projected actual emissions'' (PAE) which predict future emissions, based on several factors including business projections. PAE also allows a source to exclude from consideration those emissions which could legally and physically have been emitted prior to the modification. DDOE's regulations (and indeed EPA's pre-reform regulations) require sources to use the full potential to emit (PTE) to calculate the increase, and do not allow for the exclusion of emissions that the facility could have accommodated prior to the change. This is codified in the definition of ``net emissions increase,'' previously at 20 DCMR section 199.1. In the proposed revisions, that definition is re-codified under section 299.1, however the substantive requirements are not changed. It is also important to note that, because DDOE's regulations do not allow for the use of PAE, and because every source wishing to construct or modify in DC must receive authorization from DDOE prior to doing so, the ``reasonable possibility'' provisions of NSR Reform do not apply.
-
Plantwide Applicability Limits (PALs)
The most notable component of the 2002 NSR Reform rules being adopted by DC are provisions for DDOE to issue Plantwide Applicability Limits, or PALs. A PAL is a facility-wide, pollutant specific limit that allows sources to make modifications without triggering major NSR requirements, as long as the plantwide emissions of that pollutant do not exceed the PAL. EPA's rationale for adopting PALs in 2002 was that they would encourage the installation of newer, more efficient, and lower emitting equipment by providing sources the flexibility to do so
Page 73511
without triggering NSR requirements. For sources, the trade-off for this flexibility is a number of enhanced monitoring requirements.
Under Federal regulations, a PAL is set by calculating the facility's BAE of the PAL pollutant (as described above), and adding the significance level for that pollutant, as defined by 40 CFR 51.165(a)(1)(x)(A). Federal PALs have a term of ten years. The PAL provisions being proposed by DC for approval into the SIP differ from the Federal PAL regulations in two ways. First, PALs issued by DDOE have a five year term, rather than a ten year term. Second, as previously discussed, DDOE has not adopted BAE provisions for calculating the pre-project emissions baseline. Therefore, in order to establish the PAL, the significance level for the PAL pollutant is added to the pre-NSR Reform definition of ``actual emissions.''
-
-
PM2.5
The PM2.5 provisions submitted by DDOE for approval into the DC SIP largely mirror the 2008 NSR PM2.5 Rule, which: (1) Required NSR permits to address directly emitted PM2.5 and precursor pollutants; (2) established significant emission rates for direct PM2.5 and precursor pollutants (including sulfur dioxide (SO2) and oxides of nitrogen (NOX)); (3) established PM2.5 emission offsets; and (4) required states to account for gases that condense to form particles (condensables) in PM2.5 emission limits.
Additionally, DDOE's submittal includes provisions allowing sources to offset emissions increases of direct PM2.5 emissions or PM2.5 precursors with reductions of either direct PM2.5 emissions or PM2.5 precursors in accordance with offset ratios contained in the approved SIP for the applicable nonattainment area. DDOE's submittal does not, however, contain the presumptive offset trading ratios from the 2008 NSR PM2.5 Rule that were subject to the petition for reconsideration. As previously discussed, while the presumptively approvable interpollutant trading ratios from the 2008 NSR PM2.5 Rule are no longer supported, EPA does continue to support the policy allowing an interpollutant offset program. However, in order for sources in DC to utilize such a program, DDOE must develop and submit to EPA for approval, a technical demonstration justifying the ratios to be used, and showing the net air quality benefits of such ratio for the PM2.5 nonattainment area in which it will be applied.
EPA is in the process of evaluating the requirements of subpart 4 as they pertain to nonattainment NSR. In particular, subpart 4 includes section 189(e) of the CAA, which requires the control of major stationary sources of PM10 precursors (and hence under the court decision, PM2.5 precursors) ``except where the Administrator determines that such sources do not contribute significantly to PM10 levels which exceed the standard in the area.'' The evaluation of which precursors need to be controlled to achieve the standard in a particular area is typically conducted in the context of the state's preparing and the EPA's reviewing of an area's attainment plan SIP. In this case, there was previously only one designated PM2.5 nonattainment area, the DC portion of the Washington, DC-MD-VA nonattainment area for the 1997 annual PM2.5 NAAQS.
With respect to this nonattainment area, DDOE submitted an attainment plan on April 2, 2008. On January 12, 2009, EPA finalized a clean data determination for the area, (74 FR 1146), which suspended the requirement for DDOE to submit, among other things, an attainment plan SIP for the area. Accordingly, on February 6, 2012, DDOE withdrew the attainment plan SIP, and it is no longer before EPA. Moreover, on October 6, 2014, (FR 60081), EPA took final action to redesignate the Metro-Washington area to attainment. This redesignation absolves the District of any further obligation to comply with the subpart 4 requirements for nonattainment NSR as to this area unless and until there is a future designation of nonattainment for a PM2.5 NAAQS. Therefore, EPA is not evaluating the April 5, 2013 submittal for the purposes of determining compliance with the subpart 4 requirements.
-
Proposed Action
EPA's review of this material indicates that with the proposed amendments to the DC Municipal Regulations, DDOE's nonattainment NSR program is equivalent to, and at least as stringent as Federal regulations. Therefore, EPA is proposing to approve the DC SIP revision which was submitted on April 5, 2013. EPA is not acting on DDOE's submittal for purposes of determining compliance with the subpart 4 requirements relating to PM2.5. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed 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);
does 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.);
does 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);
does not have Federalism implications as specified in Executive 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 CAA; and
does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this proposed rule, relating to the District of Columbia's nonattainment NSR program, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
