ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[DE100-2014 & DC100-1017; FRL-6193-6]


Approval and Promulgation of Air Quality Implementation Plans; 
Delaware and District of Columbia; Revised Format for Materials Being 
Incorporated by Reference

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; notice of administrative change.

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

SUMMARY: EPA is revising the format of 40 CFR part 52 for materials 
submitted by Delaware and the District of Columbia that are 
incorporated by reference (IBR) into their respective State 
implementation plans (SIPs). The regulations affected by this format 
change have all been previously submitted by the respective State 
agency and approved by EPA. This format revision will primarily affect 
the ``Identification of plan'' sections of CFR part 52, as well as the 
format of the SIP materials that will be available for public 
inspection at the Office of the Federal Register (OFR), the Air and 
Radiation Docket and Information Center located in Waterside Mall, 
Washington, D.C., and the Regional Office. The sections of 40 CFR part 
52 pertaining to provisions promulgated by EPA or State-submitted 
materials not subject to IBR review remain unchanged.

EFFECTIVE DATE: This final rule is effective on December 7, 1998.

ADDRESSES: Copies of the documents relevant to this action are 
available for public inspection during normal business hours at the Air 
Protection Division, U.S. Environmental Protection Agency, Region III, 
1650 Arch Street, Philadelphia, Pennsylvania 19103; the Air and 
Radiation Docket and Information Center, U.S. Environmental Protection 
Agency, 401 M Street, SW, Washington, DC 20460; Delaware Department of 
Natural Resources & Environmental Control, 89 Kings Highway, P.O. Box 
1401, Dover, Delaware 19903; and the District of Columbia Department of 
Public Health, Air Quality Division, 2100 Martin Luther King Ave, S.E., 
Washington, DC 20020.

What a SIP Is

    Each state has a SIP containing the control measures and strategies 
used to attain and maintain the national ambient air quality standards 
(NAAQS). The SIP is extensive, containing such elements as air 
pollution control regulations, emission inventories, monitoring 
network, attainment demonstrations, and enforcement mechanisms.

[[Page 67408]]

How EPA Enforces SIPs

    Each state must formally adopt the control measures and strategies 
in the SIP after the public has had an opportunity to comment on them. 
They are then submitted to EPA as SIP revisions on which EPA must 
formally act.
    Once these control measures and strategies are approved by EPA, 
after notice and comment, they are incorporated into the Federally 
approved SIP and are identified in Part 52 (Approval and Promulgation 
of Implementation Plans), title 40 of the Code of Federal Regulations 
(40 CFR Part 52). The actual state regulations approved by EPA are not 
reproduced in their entirety in 40 CFR Part 52, but are ``incorporated 
by reference'' which means that EPA has approved a given state 
regulation with a specific effective date. This format allows both EPA 
and the public to know which measures are contained in a given SIP and 
ensures that the state is enforcing the regulations. It also allows EPA 
and the public to take enforcement action, should a state not enforce 
its SIP-approved regulations.

How the State and EPA Updates the SIP

    The SIP is a living document which the state can revise as 
necessary to address the unique air pollution problems in the state. 
Therefore, EPA from time to time must take action on SIP revisions 
containing new and/or revised regulations as being 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 OFR.
    EPA began the process of developing: (1) a revised SIP document for 
each state that would be IBR under the provisions of 1 CFR Part 51; (2) 
a revised mechanism for announcing EPA approval of revisions to an 
applicable SIP and updating both the IBR document and the CFR; and (3) 
a revised format of the ``Identification of Plan'' sections for each 
applicable subpart to reflect these revised IBR procedures. 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.

How EPA Compiles the SIPs

    The Federally-approved regulations, source-specific permits, and 
nonregulatory provisions (entirely or portions of) submitted by each 
state agency have been compiled by EPA into a ``SIP compilation.'' The 
SIP compilation contains the updated regulations, source-specific 
permits, and nonregulatory provisions approved by EPA through previous 
rulemaking actions in the Federal Register. The compilations are 
contained in three-ring binders and will be updated, primarily on an 
annual basis.

How EPA Organizes the SIP Compilation

    Each compilation contains three parts. Part one contains the 
regulations, part two contains the source-specific requirements that 
have been approved as part of the SIP and part three contains 
nonregulatory provisions that have been EPA approved. Each part 
consists of a table of identifying information for each SIP-approved 
regulation, each SIP-approved source-specific permit, and each 
nonregulatory SIP provision. In this action, EPA is publishing the 
tables summarizing Parts one and two for each State. The table of 
identifying information in the compilation corresponds to the table of 
contents published in 40 CFR Part 52 for these states. EPA will publish 
the summary list of Part Three SIP provisions for Delaware and the 
District of Columbia in a separate action. EPA Regional Offices have 
the primary responsibility for ensuring accuracy and updating the 
compilations.

Where You Can Find a Copy of the SIP Compilation

    EPA Region III developed and will maintain the compilation for 
Delaware and the District of Columbia. A copy of the full text of each 
state's regulatory and source-specific SIP compilation will also be 
maintained at the OFR and EPA's Air Docket and Information Center.

The Format of the New Identification of Plan Section

    In order to better serve the public, EPA revised the organization 
of the ``Identification of Plan'' section and included additional 
information to clarify the enforceable elements of the SIP. The revised 
Identification of Plan section contains five subsections:
    1. Purpose and scope
    2. Incorporation by reference
    3. EPA-approved regulations
    4. EPA-approved source-specific permits
    5. EPA-approved nonregulatory provisions such as transportation 
control measures, statutory provisions, control strategies, monitoring 
networks, etc.

When a SIP Revision Becomes Federally Enforceable

    All revisions to the applicable SIP become Federally enforceable as 
of the effective date of the revisions to paragraphs (c), (d), or (e) 
of the applicable Identification of Plan section found in each subpart 
of 40 CFR Part 52.

The Historical Record of SIP Revision Approvals

    To facilitate enforcement of previously approved SIP provisions and 
provide a smooth transition to the new SIP processing system, EPA 
retains the original Identification of Plan section, previously 
appearing in the CFR as the first or second section of Part 52 for each 
state subpart. After an initial two-year period, EPA will review its 
experience with the new system and enforceability of previously 
approved SIP measures and will decide whether or not to retain the 
Identification of Plan appendices for some further period.

What EPA Is Doing in This Action

    Today's rule constitutes a ``housekeeping'' exercise to ensure that 
all revisions to the state programs that have occurred are accurately 
reflected in 40 CFR Part 52. State SIP revisions are controlled by EPA 
regulations at 40 CFR Part 51. When EPA receives a formal SIP revision 
request, the Agency must publish the proposed revision in the Federal 
Register and provide for public comment before approval.
    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.

How This Document Complies With the Federal Administrative 
Requirements for Rulemaking

A. Executive Order 12866

    The Office of Management and Budget (OMB) has exempted this 
regulatory action from review under E.O. 12866, entitled ``Regulatory 
Planning and Review.''

B. Executive Order 12875

    Under E.O. 12875, EPA may not issue a regulation that is not 
required by statute and that creates a mandate upon a state, local, or 
tribal government, unless the Federal government provides the funds 
necessary to pay the direct compliance costs incurred by those 
governments. If EPA complies by consulting, E.O. 12875 requires EPA to 
provide to the Office of Management and Budget a description of the 
extent of EPA's prior consultation with representatives of affected 
state, local, and tribal governments, the nature of their concerns, 
copies of written communications from the governments, and a statement 
supporting the need to issue the regulation. In addition, E.O. 12875 
requires EPA to develop an effective process permitting elected 
officials and other representatives of state, local, and tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory proposals containing significant unfunded mandates.'' 
Today's rule does not create a mandate on state, local or tribal 
governments. The rule does not impose any enforceable duties on these 
entities. Accordingly, the requirements of section 1(a) of E.O. 12875 
do not apply to this rule.

C. Executive Order 13045

    Executive Order 13045, entitled ``Protection of Children from 
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
1997), applies to any rule that EPA determines (1) is ``economically 
significant,'' as defined under Executive Order 12866, and (2) the 
environmental health or safety risk addressed by the rule has a 
disproportionate effect on children. If the regulatory action meets 
both criteria, the Agency must evaluate the environmental health or 
safety effects of the planned rule on children and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    This final rule is not subject to Executive Order 13045 because it 
is not an economically significant regulatory action as defined by 
Executive Order 12866, and it does not address an environmental health 
or safety risk that would have a disproportionate effect on children.

D. Executive Order 13084

    Under E.O. 13084, EPA may not issue a regulation that is not 
required by statute, that significantly affects or uniquely affects the 
communities of Indian tribal governments, and that imposes substantial 
direct compliance costs on those communities, unless the Federal 
government provides the funds necessary to pay the direct compliance 
costs incurred by the tribal governments. If EPA complies by 
consulting, E.O. 13084 requires EPA to provide to the Office of 
Management and Budget, in a separately identified section of the 
preamble to the rule, a description of the extent of EPA's prior 
consultation with representatives of affected tribal governments, a 
summary of the nature of their concerns, and a statement supporting the 
need to issue the regulation. In addition, Executive Order 13084 
requires EPA to develop an effective process permitting elected and 
other representatives of Indian tribal governments ``to provide 
meaningful and timely input in the development of regulatory policies 
on matters that significantly or uniquely affect their communities.'' 
Today's rule does not significantly or uniquely affect the communities 
of Indian tribal governments. This action does not involve or impose 
any requirements that affect Indian Tribes. Accordingly, the 
requirements of section 3(b) of E.O. 13084 do not apply to this rule.

E. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. This final rule will not have a significant impact on a 
substantial number of small entities because SIP approvals under 
section 110 and subchapter I, part D of the Clean Air Act do not create 
any new requirements but simply approve requirements that the State is 
already imposing. Therefore, because the Federal SIP approval does not 
create any new requirements, I certify that this action will not have a 
significant economic impact on a substantial number of small entities. 
Moreover, due to the nature of the Federal-State relationship under the 
Clean Air Act, preparation of a flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of state action. The 
Clean Air Act forbids EPA to base its actions concerning SIPs on such 
grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 
42 U.S.C. 7410(a)(2).

F. Unfunded Mandates

    Under Section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
annual costs to State, local, or tribal governments in the aggregate; 
or to private sector, of $100 million or more. Under Section 205, EPA 
must select the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires EPA to establish a plan 
for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    EPA has determined that the approval action promulgated does not 
include a Federal mandate that may result in estimated annual costs of 
$100 million or more to either State, local, or tribal governments in 
the aggregate, or to the private sector. This Federal action approves 
pre-existing requirements under State or local law, and imposes no new 
requirements. Accordingly, no additional costs to State, local, or 
tribal governments, or to the private sector, result from this action.

G. 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).

H. 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

[[Page 67410]]

judicial review are not applicable to this action. Prior EPA rulemaking 
actions for each individual component of the Delaware and District of 
Columbia 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 
these ``Identification of plan'' reorganization actions for Delaware 
and the District of Columbia.
