Approval and Promulgation of Air Quality Implementation Plans; District
of Columbia; Section 110(a)(2) Infrastructure Requirements for the 1997
8-Hour Ozone and the 1997 and 2006 Fine Particulate Matter National
Ambient Air Quality Standards

AGENCY:  Environmental Protection Agency (EPA).

ACTION:  Proposed rule.

SUMMARY:  EPA is proposing to approve submittals from the District of
Columbia (the District) pursuant to the Clean Air Act (CAA) sections

SUPPLEMENTARY INFORMATION:  

I.  Background 

On July 18, 1997, EPA promulgated a revised 8-hour ozone NAAQS (62 FR
38856) and a new PM2.5 NAAQS (62 FR 38652).  The revised ozone NAAQS is
based on 8-hour average concentrations.  The 8-hour averaging period
replaced the previous 1-hour averaging period, and the level of the
NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm.  The
new PM2.5 NAAQS established a health-based standard of 15.0 micrograms
per cubic meter (µg/m3) based on a 3-year average of annual mean PM2.5
concentrations, and a 24-hour standard of 65 µg/m3 based on a 3-year
average of the 98th percentile of 24-hour concentrations.  EPA
strengthened the 24-hour PM2.5 NAAQS from 65 µg/m3 to 35 µg/m3 on
October 17, 2006 (71 FR 61144).  

Section 110(a) of the CAA requires States to submit State Implementation
Plans (SIPs) that provide for the implementation, maintenance, and
enforcement of new or revised NAAQS within three years following the
promulgation of such NAAQS.  In March of 2004, Earthjustice initiated a
lawsuit against EPA for failure to take action against States that had
not made SIP submissions to meet the requirements of sections 110(a)(1)
and (2) for the 1997 8-hour ozone and PM2.5 NAAQS, i.e., failure to make
a “finding of failure to submit the required SIP 110(a) SIP
elements.”  On March 10, 2005, EPA entered into a Consent Decree with
Earthjustice that obligated EPA to make official findings, in accordance
with section 110(k)(1) of the CAA as to whether States have made
complete SIP submissions, pursuant to sections 110(a)(1) and (2), by
December 15, 2007 for the 1997 8-hour ozone NAAQS, and by October 5,
2008 for the 1997 PM2.5 NAAQS.  EPA made completeness findings for the
1997 8-hour ozone NAAQS on March 27, 2008 (73 FR 16205) and on October
22, 2008 (73 FR 62902) for the 1997 PM2.5 NAAQS.  These completeness
findings did not include findings relating to:  1) section 110(a)(2)(C)
to the extent that such subsection refers to a permit program as
required by Part D Title I of the CAA; 2) section 110(a)(2)(I);  and 3)
section 110(a)(2)(D)(i), which has been addressed by a separate finding
issued by EPA on April 25, 2005 (70 FR 21147).  Therefore, this action
does not cover these specific elements. 

                                                                     

II.   Summary of State Submittal

The District provided multiple submittals to satisfy section 110(a)(2)
requirements, that are the subject of this proposed rule for the 1997
8-hour ozone NAAQS and the 1997 and 2006 PM2.5 NAAQS.  The submittals
dated December 6, 2007 and January 11, 2008 addressed the 110(a)(2)
requirements for the 1997 8-hour ozone NAAQS;  the submittals dated
August 25, 2008 and September 22, 2008 addressed the 110(a)(2)
requirements for the 1997 PM2.5 NAAQS; and the submittal dated September
21, 2009 addressed the section 110(a)(2) requirements for the 2006 PM2.5
NAAQS.  These submittals addressed the following infrastructure
elements, that are the subject of this proposed rule:  110(a)(2)(A),
(B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M).          
                                                                        
                                                                        

EPA has analyzed the above identified submissions and is proposing to
make a determination that such submittals meet the requirements of
110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and
(M).  A detailed summary of EPA’s review of and rationale for
approving the District’s submittals may be found in the Technical
Support Document (TSD) for this action which is available on line at  
HYPERLINK "http://www.regulations.gov"  www.regulations.gov , Docket
number EPA-R03-OAR-2010-0139.  

III.   Proposed Action 

EPA is proposing to approve the District of Columbia’s submittals that
provide the basic program elements specified in the CAA sections
110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and
(M) necessary to implement, maintain, and enforce the 1997 8-hour ozone
and PM2.5 NAAQS and the 2006 PM2.5 NAAQS.  EPA is soliciting public
comments on the issues discussed in this document.  These comments will
be considered before taking final action. 

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 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
proposes to approve 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 (Public Law 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, pertaining to the District of
Columbia’s section 110(a)(2) infrastructure requirements for the 1997
8-hour ozone and PM2.5 NAAQS and the 2006 PM2.5 NAAQS, 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.
