SUPPLEMENTARY INFORMATION:

[[Page 56131]]

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 
PM2.5 standard of 15.0 micrograms per cubic meter ([mu]g/
m\3\) based on a 3-year average of annual mean PM2.5 
concentrations, and a twenty-four hour standard of 65 [mu]g/m\3\ based 
on a 3-year average of the 98th percentile of 24-hour concentrations. 
EPA strengthened the 24-hour PM2.5 NAAQS from 65 [mu]g/m\3\ 
to 35 [mu]g/m\3\ 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 required 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 such 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 had 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.
    This action also does not include the portions of sections 
110(a)(2)(C), (D)(i)(II), and (J) as they pertain to the PSD permit 
program, and the portion of section 110(a)(2)(D)(i)(II) as it pertains 
to visibility. These portions of these elements will be addressed by 
separate actions.

II. Summary of State Submittal

    Maryland provided multiple submittals to satisfy the section 
110(a)(2) requirements that are the subject of this proposed action for 
the 1997 8-hour ozone NAAQS and the 1997 and 2006 PM2.5 
NAAQS. The submittals shown in Table 1 address the infrastructure 
elements, or portions thereof, identified in section 110(a)(2) that EPA 
is proposing to approve.

----------------------------------------------------------------------------------------------------------------

    EPA analyzed the above identified submissions and other related 
submissions. Based upon this analysis, EPA is proposing to make a 
determination that such submittals meet the requirements of section 
110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and 
(M), or portions thereof, for the 1997 8-hour ozone and 
PM2.5 NAAQS and the 2006 PM2.5 NAAQS. A detailed 
summary of EPA's review of and rationale for approving Maryland's 
submittals may be found in the Technical Support Document (TSD) for 
this action, which is available online at http://www.regulations.gov, 
Docket number EPA-R03-OAR-2011-0476.

III. Proposed Action

    EPA is proposing to approve Maryland'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), or portions 
thereof, 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 
notice and the related TSD. 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 (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);

[[Page 56132]]

     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 Maryland'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.
