**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to partially approve and partially disapprove State Implementation Plan (SIP) revisions submitted by the State of Colorado on June 20, 2003. The intended effect of this proposal is to approve and make federally enforceable those portions of the revisions to Colorado’s Common Provisions that are consistent with the Clean Air Act (CAA). Primarily, the revisions involved changes designed to fix ambiguous language, to make the definitions more readable or to delete obsolete definitions. In addition, a number of definitions were revised to reflect developments in federal law or were deleted to eliminate duplicative provisions that appear in other Colorado regulations. EPA is proposing to approve parts of the revision that delete duplicative or obsolete definitions, or that clarify existing definitions in a manner consistent with the CAA. In addition, EPA proposes to disapprove those portions of the rule revisions that EPA determined are inconsistent with the CAA. This action is being taken under section 110 of the CAA.

h. Make sure to submit your comments by the comment period deadline identified. II. Background of State’s Submittal

On June 20, 2003, the State of Colorado submitted formal revisions to its SIP that changed or deleted numerous definitions in its Common Provisions. Colorado’s Common Provisions provide definitions, statement of intent and general provisions that are applicable to all emission control regulations adopted by the State. Primarily, this revision involved changes designed to fix ambiguous language, to make the definitions more readable or to delete obsolete definitions. In addition, a number of definitions were revised to reflect developments in federal law or deleted to eliminate duplicative provisions that appear in other Colorado regulations.

Definitions deleted include: Actual emissions, allowable emissions, BACT, LAER and the modification of a source. These definitions were deleted from the Common Provisions because the State placed these definitions in their Regulation 3.

Revisions to the Common Provisions also include grammatical, formatting and stylistic changes designed to make the regulation more readable. The State made these revisions to achieve consistency in the language used in the State’s air quality regulations. These revisions do not change the applicability of any of the air quality regulation requirements. The State also added a number of abbreviations to the existing list.

The State clarified when fuel burning equipment would be considered part of a manufacturing process. The revisions to the Common Provisions change the definition of fuel burning and added a definition for manufacturing process equipment. The result was to clarify that fuel burning emissions are counted as manufacturing process emissions when they are vented through a common stack with other emissions from the manufacturing process. When fuel burning emissions are vented separately, the emissions are subject to regulations unique to fuel burning equipment.

The definition of construction was changed to clarify the distinction between the State’s definition and the definition in federal programs. The clarification acknowledges that federal programs may utilize different definitions of construction and, in cases where enforceability of Federal programs are involved, the federal program definitions apply.

The State determined that many of its definitions in the Common Provisions were either obsolete or found in other State air quality regulations. In those cases, the State eliminated the definitions from the Common Provisions. Section III refers to smoking gasoline powered motor vehicles. Section IV addresses conflict of interest by AQCC members. The State deleted these sections because they are duplicated in other State regulations. III. EPA Analysis of State’s Submittal

We have evaluated Colorado’s June 20, 2003 submittal regarding revisions to the State’s Common Provisions. We propose to approve most of the revisions, but also propose to disapprove certain revisions within the June 20, 2003 submittal. What EPA Is Proposing To Disapprove

The State provided, within Section I of the Common Provisions, a new definition for what constitutes the meaning of the word ‘‘day.’’ The new definition gives the Colorado Air Pollution Control Division discretion to change the meaning of day from the standard one to any other twenty-four hour period. Given that a day is often the time period for expressing emissions limitations, the revised definition potentially gives the State discretion, without going through a SIP revision, to modify emissions limitations for stationary sources. Such discretion violates section 110(i) of the CAA, which prohibits States (except in certain limited circumstances) from taking any action to modify requirements of a SIP with respect to stationary sources, except through a SIP revision. EPA proposes to disapprove this definition.

The State added language to its definition of ‘‘construction’’ for the purposes of prevention of significant deterioration (PSD) and new source review (NSR). The revised definition, for the most part, tracks those given at 40 CFR 51.165(a)(1)(xviii) and 51.166(b)(8). However, instead of providing that construction encompasses those changes that would result in an increase in emissions, the State’s revision encompasses only those changes that would result in an increase in ‘‘actual emissions.’’ ‘‘Actual emissions,’’ in the context of PSD and NSR, is a defined term that in general equals past emissions over a consecutive 24-month period that is representative of normal operations (see 40 CFR 51.165(a)(1)(xii)(B), 51.166(b)(21)(ii)). It is not clear how past emissions, prior to a change due to construction, could be representative of normal operations after the change. In any case, the revision is less stringent than Federal requirements and EPA therefore proposes to disapprove it.

Colorado revised section II.I, relating to compliance certifications. Section II.I in the current SIP governs the use of credible evidence or information in compliance certifications and in establishing violations of the Colorado SIP. It reflects language at 40 CFR 51.212(c), promulgated by EPA on February 24, 1997 in the ‘‘Credible Evidence Rule’’ (62 FR 8314). The revision adds (in part) the following language: ‘‘Evidence that has the effect of making any relevant standard or permit term more stringent shall not be


### 4270 Federal Register / Vol. 76, No. 16 / Tuesday, January 25, 2011 / Proposed Rules

credible for proving a violation of the standard or permit term.’’ In the preamble to the Credible Evidence Rule, EPA stated that it was not EPA’s intent to increase the stringency of any applicable requirement and that the Credible Evidence Rule did not do so (62 FR at 8323). EPA discussed at length and rejected the arguments made by commenters to the contrary (62 FR at 8323–27). For the reasons discussed within the preamble to the Credible Evidence Rule, credible evidence does not increase the stringency of any applicable requirement. EPA therefore proposes to disapprove the revision to section II.I.

EPA proposes to disapprove the deletion of Section IV of the Common Provisions. Section IV refers to provisions regarding potential conflicts of interest of members of the Colorado AQCC. These provisions require the disclosure of information when a potential conflict of interest has been identified. Section 128(a)(2) of the CAA requires that each SIP contain requirements for disclosure of potential conflicts of interest of heads of executive agencies or members of state boards that approve permits or enforcement orders under the CAA. In deleting Section IV, Colorado had intended to submit substitute provisions contained within the rules of procedure for the AQCC; however, Colorado has not submitted them to EPA for inclusion into Colorado’s SIP. As the SIP is required to have such provisions, EPA proposes to disapprove the deletion of Section IV.

Finally, the State revised the provision of Affirmative Defense for excess emissions during start up, shutdown and malfunction of equipment. The State in subsequent revisions sent to EPA modified the Affirmative Defense provision. EPA acted on these subsequent revisions in 2008 and the results of the action can be found in 40 CFR 52.320(c)113. Therefore, we are taking no action on the portion of the revision modifying the Affirmative Defense provision within the June 20, 2003 submittal because our subsequent action on the provision has superseded this revision. What EPA Is Proposing To Approve

EPA proposes to approve specific definitions that were added or modified with the June 20, 2003 Common Provisions. These include the definitions for a continuous monitoring system, emergency power generator, manufacturing process, enforceable, federally enforceable, manufacturing process or processing equipment, and volatile organic compounds. The new and modified definitions are consistent with the requirements of the CAA and do not change the stringency of any requirements of the SIP.

Changes that correct numerous grammatical, stylistic and formatting errors within the Common Provisions are proposed for approval by EPA. EPA also proposes to approve the deletion of definitions and Section III that are obsolete or duplicated elsewhere in Colorado’s SIP.

IV. Consideration of Section 110(l) of the CAA

Section 110(l) of the CAA states that a SIP revision cannot be approved if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress toward attainment of the NAAQS or any other applicable requirement of the Act. The Colorado SIP revisions being approved that are the subject of this document do not interfere with attainment of the NAAQS or any other applicable requirement of the Act. In regard to the June 20, 2003 submittal, EPA proposes to approve several portions of the revisions to the State’s Common Provisions. These portions do not relax the stringency of the Colorado SIP and in some cases strengthen it. Therefore, the portions of the revisions proposed for approval satisfy section 110(l). V. Proposed Action

For the reasons expressed above, we propose to approve and disapprove revisions to the Common Provisions as submitted on June 20, 2003. EPA proposes to approve specific definitions that were added or modified with the June 20, 2003 Common Provisions. These include the definitions for continuous monitoring system, emergency power generator, manufacturing process, enforceable, federally enforceable, manufacturing process or processing equipment, and volatile organic compounds.

Changes that correct numerous grammatical, stylistic and formatting errors, duplicative and obsolete provisions, and the addition of several abbreviations within the Common Provisions are also proposed for approval by EPA. This includes the deletion of Section III of the Common Provisions regarding smoking gasoline powered motor vehicles.

EPA proposes to disapprove the modified definitions of ‘‘construction’’ and ‘‘day.’’ The additional language added to Section II.I regarding credible evidence in submitting compliance certifications is disapproved. EPA proposes to disapprove the deletion of Section IV of the Common Provisions. Section IV refers to provisions regarding the conflicts of interest involving members of the AQCC. These provisions provide for the disclosure of information when a potential conflict of interest has been identified.

EPA will not act on Sections II.E and II.J, defining the provision of Affirmative Defense for excess emissions during start up, shutdown and malfunction of equipment. The State in subsequent revisions sent to EPA modified the Affirmative Defense provision. EPA acted on these subsequent revisions in 2008 (40 CFR 52.320(c)(113)). VI. Statutory and Executive Order Review

Under the CAA, 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 CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this 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 sq. );

• 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


### 4271 Federal Register / Vol. 76, No. 16 / Tuesday, January 25, 2011 / Proposed Rules

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 rule 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.

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 action 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. A major rule cannot take effect until 60 days after it is published in the Federal Register

. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). List of Subjects in 40 CFR Part 52

Environmental protection, Air pollution control, Carbon monoxide, Intergovernmental relations, Lead, Nitrogen dioxide, Ozone, Particulate matter, Reporting and recordkeeping requirements, Sulfur oxides, Volatile organic compounds.
