40 CFR Part 52

[DE102-1100; FRL-8291-7]


Approval and Promulgation of Air Quality Implementation Plans; 
Delaware; Update to Materials Incorporated by Reference

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; notice of administrative change.

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

SUMMARY: EPA is updating the materials submitted by Delaware that are 
incorporated by reference (IBR) into the State implementation plan 
(SIP). The regulations affected by this update have been previously 
submitted by the Delaware Department of Natural Resources and 
Environmental Control (DNREC) and approved by EPA. This update affects 
the SIP materials that are available for public inspection at the 
National Archives and Records Administration (NARA), the Air and 
Radiation Docket and Information Center located at EPA Headquarters in 
Washington, D.C., and the Regional Office.

EFFECTIVE DATE: This action is effective April 3, 2007.

ADDRESSES: SIP materials which are incorporated by reference into 40 
CFR part 52 are available for inspection at the following locations: 
Air Protection Division, U.S. Environmental Protection Agency, Region 
III, 1650 Arch Street, Philadelphia, Pennsylvania 19103; the Air and 
Radiation Docket and Information Center, EPA Headquarters Library, Room 
Number 3334, EPA West Building, 1301 Constitution Ave., NW., 
Washington, DC 20460, and the National Archives and Records 
Administration. If you wish to obtain materials from a docket in the 
EPA Headquarters Library, please call the Office of Air and Radiation 
(OAR) Docket/Telephone number: (202) 566-1742; or the National Archives 
and Records Administration (NARA). For information on the availability 
of this material at NARA, call 202-741-6030, or go to: http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_locations.html.

by e-mail at [email protected].

SUPPLEMENTARY INFORMATION: The SIP is a living document which the State 
revises as necessary to address the unique air pollution problems. 
Therefore, EPA from time to time must take action on SIP revisions 
containing new and/or revised regulations to make them part of the SIP. 
On May 22, 1997 (62 FR 27968), EPA revised the procedures for 
incorporating by reference Federally-approved SIPs, as a result of 
consultations between EPA and the Office of the Federal Register (OFR). 
The description of the revised SIP document, IBR procedures and 
``Identification of plan'' format are discussed in further detail in 
the May 22, 1997 Federal Register document. On December 7, 1998 (63 FR 
67407), EPA published a document in the Federal Register beginning the 
new IBR procedure for Delaware. On June 21, 2004 (69 FR 34285), EPA 
published an update to the IBR material for Delaware. In this document, 
EPA is doing the following:
    1. Announcing the update to the IBR material as of February 15, 
2007.
    2. Making corrections to the following entries listed in the 
paragraph 52.420(c) chart, as described below:
    a. Revising the title of Regulation 1102 (formerly Regulation 2) so 
that it restores the text of the revised title as published in the 
December 7, 2006 Federal Register (71 FR 70883 at 70885).
    b. Adding an entry for Regulation 1102, Appendix A with a State 
effective date of June 1, 1997. EPA had approved the addition of this 
appendix as a SIP revision on January 13, 2000 (65 FR 2005), but had 
inadvertently omitted a corresponding entry as an addition to 40 CFR 
52.420(c) at the time of EPA's approval action.
    c. For the entries Regulation 1102, Sections 1, 6, 11, and 12, 
adding text in the ``Additional explanation'' column to indicate the 
SIP effective date.
    d. For the entry Regulation 24, Section 10, removing the text from 
the ``Additional explanation'' column.
    e. For the entry Regulation 31, Appendix 6(a)(9), correcting a 
typographical error in the ``Title/subject'' column.
    3. Making corrections to the following entries listed in the 
paragraph 52.420(d) chart, as described below:
    a. Renaming the title of the second column from ``Title/subject'' 
to ``Permit number.''
    b. Entry for Phoenix Steel Co.--Electric Arc Furnaces Charging & 
Tapping 2--Correcting a typographical error in the ``Permit 
number'' column.
    EPA has determined that today's rule falls under the ``good cause'' 
exemption in section 553(b)(3)(B) of the Administrative Procedures Act 
(APA), which, upon finding ``good cause,'' authorizes agencies to 
dispense with public participation, and section 553(d)(3), which allows 
an agency to make a rule effective immediately (thereby avoiding the 
30-day delayed effective date otherwise provided for in the APA). 
Today's rule simply codifies provisions which are already in effect as 
a matter of law in Federal and approved State programs. Under section 
553 of the APA, an agency may find good cause where procedures are 
``impractical, unnecessary, or contrary to the public interest.'' 
Public comment is ``unnecessary'' and contrary to the ``public 
interest'' since the codification only reflects existing law. Immediate 
notice in the CFR benefits the public by removing outdated citations 
and incorrect chart entries.

Statutory and Executive Order Reviews

A. General Requirements

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. For this 
reason, this action is also not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action 
merely approves state law as meeting Federal requirements and imposes 
no additional requirements beyond those imposed by state law. 
Accordingly, the Administrator certifies that this rule will not have a 
significant economic impact on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because 
this rule approves pre-existing requirements under state law and does 
not impose any additional enforceable duty beyond that required by 
State law, it 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). This rule also does not 
have tribal implications because it will not have a substantial direct 
effect on one or more Indian tribes, on the relationship between the 
Federal Government and Indian tribes, or on the distribution of power 
and responsibilities between the Federal Government and Indian tribes, 
as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). 
This action also does not have Federalism implications because it does 
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

[[Page 15840]]

levels of government, as specified in Executive Order 13132 (64 FR 
43255, August 10, 1999). This action merely approves a state rule 
implementing a Federal standard, and does not alter the relationship or 
the distribution of power and responsibilities established in the Clean 
Air Act. This rule also is not subject to Executive Order 13045 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997), because it approves a state rule 
implementing a Federal standard. In reviewing SIP submissions, EPA's 
role is to approve state choices, provided that they meet the criteria 
of the Clean Air Act. In this context, in the absence of a prior 
existing requirement for the State to use voluntary consensus standards 
(VCS), EPA has no authority to disapprove a SIP submission for failure 
to use VCS. It would thus be inconsistent with applicable law for EPA, 
when it reviews a SIP submission, to use VCS in place of a SIP 
submission that otherwise satisfies the provisions of the Clean Air 
Act. Thus, the requirements of section 12(d) of the National Technology 
Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. 
This rule does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et 
seq.).

B. Submission to Congress and the Comptroller General

    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 
United States. 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 United States prior 
to publication of the rule in the Federal Register. This rule is not a 
``major rule'' as defined by 5 U.S.C. 804(2).

C. Petitions for Judicial Review

    EPA has also determined that the provisions of section 307(b)(1) of 
the Clean Air Act pertaining to petitions for judicial review are not 
applicable to this action. Prior EPA rulemaking actions for each 
individual component of the Delaware SIP compilations had previously 
afforded interested parties the opportunity to file a petition for 
judicial review in the United States Court of Appeals for the 
appropriate circuit within 60 days of such rulemaking action. Thus, EPA 
sees no need in this action to reopen the 60-day period for filing such 
petitions for judicial review for this ``Identification of plan'' 
reorganization update action for Delaware.
