Environmental Protection Agency (EPA).


Final rule; notice of administrative change.


EPA is revising the format for materials submitted by Maryland that are incorporated by reference (IBR) into its State implementation plan (SIP). The regulations affected by this format change have all been previously submitted by Maryland and approved by EPA. This format revision will primarily affect the “Identification of plan” section, as well as the format of the SIP materials that will be 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, DC, and the EPA Regional Office. EPA is also adding a table in the “Identification of plan” section which summarizes the approval actions that EPA has taken on the non-regulatory and quasi-regulatory portions of the Maryland SIP.


Effective Date: This final rule is effective on November 29, 2004.


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, U.S. Environmental Protection Agency, 1301 Constitution Avenue NW., Room B108, Washington, DC 20460; or the National Archives and Records Administration (NARA).

II. What EPA Is Doing in This Action

III. Statutory and Executive Order Reviews

I. Background

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.

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 upon 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” (IBR'd) 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 must, from time to time, take action on SIP revisions containing new and/or revised regulations in order to make them part of the SIP. On May 22, 1997 (62 FR 27968), EPA revised the procedures for IBR'ing Federally-approved SIPs, as a result of consultations between EPA and the Office of the Federal Register (OFR).

EPA began the process of developing: (1) A revised SIP document for each state that would be IBR'd under the provisions of title 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.

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 the applicable SIP requirements for Maryland. The EPA Regional Offices have the primary responsibility for updating the compilations and ensuring their accuracy.

Where you can find a copy of the SIP compilation—EPA Region III developed and will maintain the compilation for Maryland. A copy of the full text of Maryland's regulatory and source-specific SIP compilation will also be maintained at NARA 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 and quasi-regulatory provisions such as air quality attainment plans, rate of progress plans, maintenance plans, monitoring networks, and small business assistance programs.

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.

II. 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 Start Printed Page 69306provisions 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.

III. 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 is therefore not subject to review by the Office of Management and Budget. This rule is not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866. Because the agency has made a “good cause” finding that this action is not subject to notice-and-comment requirements under the Administrative Procedure Act or any other statute as indicated in the Supplementary Information section above, it is not subject to the regulatory flexibility provisions of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), or to sections 202 and 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4). In addition, this action does not significantly or uniquely affect small governments or impose a significant intergovernmental mandate, as described in sections 203 and 204 of UMRA. This rule also does 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), nor will it 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 levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This rule also is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997), because it is not economically significant. This rule does not involve technical standards; 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. The rule also does not involve special consideration of environmental justice related issues as required by Executive Order 12898 (59 FR 7629, February 16, 1994). In issuing this rule, EPA has taken the necessary steps to eliminate drafting errors and ambiguity, minimize potential litigation, and provide a clear legal standard for affected conduct, as required by section 3 of Executive Order 12988 (61 FR 4729, February 7, 1996). EPA has complied with Executive Order 12630 (63 FR 8859, March 15, 1998) by examining the takings implications of the rule in accordance with the “Attorney General's Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings” issued under the executive order. This rule does not impose an information collection burden under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). EPA's compliance with these statutes and Executive Orders for the underlying rules are discussed in previous actions taken on the State's rules.

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. Section 808 allows the issuing agency to make a rule effective sooner than otherwise provided by the CRA if the agency makes a good cause finding that notice and public procedure is impracticable, unnecessary or contrary to the public interest. Today's action simply codifies provisions which are already in effect as a matter of law in Federal and approved State programs. 5 U.S.C. 808(2). As stated previously, EPA has made such a good cause finding, including the reasons therefore, and established an effective date of November 29, 2004. 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 Maryland 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 Maryland.
