completeness findings pursuant to CAA section 110(K)(1) for the 1997 8-
hour ozone NAAQS, dated March 27, 2008, and the 1997 PM2.5 
NAAQS, dated October 22, 2008: 110(a)(2)(A), (B), (C), (D)(ii), (E), 
(F), (G), (H), (J), (K), (L), and (M), or portions thereof.

Confidential Business Information (CBI) or other information whose 
disclosure is restricted by statute. Do not submit information that you 
consider to be CBI or otherwise protected through http://www.regulations.gov or e-mail. The http://www.regulations.gov Web site 
is an ``anonymous access'' system, which means EPA will not know your 
identity or contact information unless you provide it in the body of 
your comment. If you send an e-mail comment directly to EPA without 
going through http://www.regulations.gov, your e-mail address will be 
automatically captured and included as part of the comment that is 
placed in the public docket and made available on the Internet. If you 
submit an electronic comment, EPA recommends that you include your name 
and other contact information in the body of your comment and with any 
disk or CD-ROM you submit. If EPA cannot read your comment due to 
technical difficulties and cannot contact you for clarification, EPA 
may not be able to consider your comment. Electronic files should avoid 
the use of special characters, any form of encryption, and be free of 
any defects or viruses.
    Docket: All documents in the electronic docket are listed in the 
http://www.regulations.gov index. Although listed in the index, some 
information is not publicly available, i.e., CBI or other information 
whose disclosure is restricted by statute. Certain other material, such 
as copyrighted material, is not placed on the Internet and will be 
publicly available only in hard copy form. Publicly available docket 
materials are available either electronically in http://www.regulations.gov or in hard copy during normal business hours at the 
Air Protection Division, U.S. Environmental Protection Agency, Region 
III, 1650 Arch Street, Philadelphia, Pennsylvania 19103. Copies of the 
State submittal are available at the Delaware Department of Natural 
Resources & Environmental Control, 89 Kings Highway, P.O. Box 1401, 
Dover, Delaware 19903.

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 
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 24-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 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 Submittals

    Delaware provided multiple submittals to satisfy 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 addressed the infrastructure elements, or 
portions thereof, identified in section 110(a)(2) that EPA is proposing 
to approve.

    EPA has analyzed the above identified submissions and 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. A detailed summary of EPA's review 
and rationale for approving Delaware's submittals may be found in the 
Technical Support Document (TSD) for this action, which is available on 
line at http://www.regulations.gov, Docket number EPA-R03-OAR-2010-
0158.

III. Proposed Action

    EPA is proposing to approve Delaware'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 
document. These comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, 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, EPA's role is to approve State 
choices, provided that they meet the criteria of the Clean Air Act. 
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);
     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
     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 Delaware'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.
