Start Preamble


Environmental Protection Agency (EPA).


Direct final rule.


EPA is taking direct final action to approve a revision to the Ventura County Air Pollution Control District (VCAPCD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NOX) and carbon monoxide (CO) from stationary internal combustion engines. In accordance with the Clean Air Act as amended in 1990 (CAA or the Act), we are taking action on a local rule that regulates these emission sources.


This rule is effective on December 24, 2002, without further notice, unless EPA receives adverse comments by November 25, 2002. If we receive such comments, we will publish a timely withdrawal in the Federal Register to notify the public that this rule will not take effect.

I. The State's Submittal

A. What Rule Did the State Submit?

Table 1 lists the rule addressed by this proposal with the dates that it was revised by the local air agency and submitted to EPA by the California Air Resources Board (CARB).

Table 1.—Submitted Rule

Local agencyRule numberRule titleRevisedSubmitted
VCAPCD74.9Stationary Internal Combustion Engines11/14/0005/08/01

On July 20, 2001, this rule submittal was found to meet the completeness criteria in 40 CFR part 51, appendix V, which must be met before formal EPA review.

B. Are There Other Versions of This Rule?

The previous version of VCAPCD Rule 74.9 is SIP Rule 74.9, Stationary Internal Combustion Engines, approved into the SIP on August 23, 1995 (60 FR 43713).

C. What Is the Purpose of the Submitted Rule Revisions?

Rule 74.9 regulates NOX and CO emissions from stationary internal combustion engines with a brake horsepower rating of 50 or greater located at a major stationary source. The SIP rule applies to such engines throughout VCAPCD, which includes the mainland severe ozone nonattainment area plus two Channel Islands designated unclassifiable. 40 CFR 81.305. The purpose of changing Rule 74.9 relative to the SIP Rule is to include an exemption to the rule for engines operated on the two Channel Islands, San Nicolas Island (SNI) and Anacapa Island (AI). The TSD has more information about this rule.

II. EPA's Evaluation and Action

A. How Is EPA Evaluating the Rule?

Generally, SIP rules must be enforceable (see section 110(a) of the CAA), must require Reasonably Available Control Technology (RACT) for major sources in nonattainment areas (see section 182(a)(2)(A)), must not interfere with applicable requirements including requirements concerning attainment (see section 110(l)), and must not relax existing requirements in effect prior to enactment of the 1990 CAA amendments (see section 193). The VCAPCD regulates sources within a severe ozone nonattainment area. 40 CFR 81.305. Therefore Rule 74.9 must fulfill RACT requirements for such sources.

Guidance and policy documents that we used to define specific enforceability and RACT requirements include the following:

  • Requirements for Preparation, Adoption, and Submittal of Implementation Plans, U.S. EPA, 40 CFR part 51.
  • Issues Relating to VOC Regulation, Cutpoints, Deficiencies, and Deviations (the “Blue Book”), U.S. EPA, OAQPS (May 25, 1988).
  • State Implementation Plans; Nitrogen Oxides Supplement to the General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990 (the “NOX Supplement to the General Preamble”), U.S. EPA, 57 FR 55620 (November 25, 1992).
  • Determination of Reasonably Available Control Technology and Best Available Retrofit Control Technology for Stationary Spark-Ignited Internal Combustion Engines, California Air Resources Board (November 2001).

B. Does the Rule Meet the Evaluation Criteria?

The revised Rule 74.9 includes an exemption for engines used on the offshore SNI and AI. The exemptions to Rule 74.9 are reasonable, because the VCAPCD federal ozone nonattainment area does not include SNI and AI and the 1994/1995 ozone Air Quality Management Plan does not rely on decreasing NOX emission controls on SNI and AI. Therefore there will be no interference with the requirements concerning attainment of the ozone National Ambient Air Quality Standards in the VCAPCD nonattainment area and the rule complies with section 110(l) of the CAA.

The revisions to Rule 74.9 do not affect the requirements for sources within the nonattainment area. For these sources, Rule 74.9 exceeds RACT requirements for NOX emission standards and meets the more stringent NOX and CO emission standards for Best Available Retrofit Control Technology (BARCT).

We believe the rule is consistent with the relevant policy and guidance regarding enforceability and SIP relaxations. The TSD has more information on our evaluation.

C. EPA Recommendations To Further Improve The Rule

The VCAPCD Rule 74.9 TSD describes additional rule revisions that do not affect EPA's current action but are recommended for the next time the local agency modifies the rule.

D. Public Comment and Final Action

As authorized in section 110(k)(3) of the CAA, EPA is fully approving the submitted rule because we believe it fulfills all relevant requirements. We do not think anyone will object to this approval, so we are finalizing the approval without proposing it in advance. However, in the Proposed Rules section of this Federal Register, we are simultaneously proposing approval of the same submitted rule. If we receive adverse comments by November 25, 2002, we will publish a timely withdrawal in the Federal Register to notify the public that the direct final approval will not take effect and we will address the comments in a subsequent final action based on the proposal. If we do not receive timely adverse comments, the direct final approval will be effective without further notice on December 24, 2002. Start Printed Page 65503This will incorporate the rule into the federally-enforceable SIP.

III. Background Information

Why Was This Rule Submitted?

NOX helps produce ground-level ozone, smog, and particulate matter which harm human health and the environment. EPA has established National Ambient Air Quality Standards (NAAQS) for ozone. Section 110(a) of the CAA requires states to submit regulations in order to achieve and maintain the NAAQS. Table 2 lists some of the national milestones leading to the submittal of these local agency NOX rules.

Table 2.—Ozone Nonattainment Milestones

March 3, 1978EPA promulgated a list of ozone nonattainment areas under the Clean Air Act as amended in 1977. 43 FR 8964; 40 CFR 81.305.
May 26, 1988EPA notified Governors that parts of their SIPs were inadequate to attain and maintain the ozone standard and requested that they correct the deficiencies (EPA's SIP-Call). See section 110(a)(2)(H) of the pre-amended Act.
November 15, 1990Clean Air Act Amendments of 1990 were enacted. Pub. L. 101-549, 104 Stat. 2399, codified at 42 U.S.C. 7401-7671 q.
May 15, 1991Section 182(a)(2)(A) requires that ozone nonattainment areas correct deficient RACT rules by this date.

IV. Administrative 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 (Public Law 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 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 CAA. 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 is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. 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 CAA. 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.).

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. 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).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 24, 2002. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).
