I. Summary of the SIP Revision

EPA is approving a formal revision to the Delaware State Implementation Plan submitted by the state on August 12, 2005. This SIP revision consists of a regulation (formerly titled Regulation No. 45) that restricts extended idling of most on-road heavy-duty vehicles (those having a gross vehicle weight rating (GVWR) of greater than 8,500 pounds) while operating in the State of Delaware. The regulation sets a time limit of three consecutive minutes of idling time (i.e., when a vehicle's engine is on, but it is not in motion). Section 5 of Delaware's Regulation No. 45 specifies exemptions to the idling limit for certain vehicle types and situations. These exemptions include: temperature-based exceptions for cold or hot days; vehicles idling for use of a sleeper berth, where the vehicle is not within 25 miles of a parking facility with available truckstop electrification equipment; vehicles which are stuck in traffic; vehicles being brought to manufacturer's recommended operating temperature; vehicles using auxiliary equipment powered by the engine (e.g., take-off power); emergency vehicles; tactical military vehicles in training operations; school and transit buses with passengers onboard (or within five minutes of passenger boarding); and situations where a vehicle is being repaired or is being tested to ensure safe operation.

Per section 1 of Delaware's rule, this rule applies to “all on-road heavy-duty motor vehicles with a GVWR of greater than 8,500 pounds operating in the State of Delaware.” Section 6 of Regulation No. 45 indicates that this regulation is enforceable under Title 7 Chapter 60 §§ 6005 and 6013 of the Delaware Code, with violators subject to a penalty of not less than $60 and no more than $500 for each offense.

On June 15, 2009, Delaware submitted a SIP revision which recodifies and makes general administrative changes to the regulatory language of its approved or submitted SIP rules. This recodification SIP revision does not change the substance of the August 2005 SIP revision, but does affect the numbering and format of the state regulation contained in the August 2005 SIP revision. EPA will take separate action on this renumbered version, Regulation No. 1145, in a separate rulemaking action along with a larger Delaware recodification SIP action.

II. What Rulemaking Action Is EPA Taking?

EPA is approving, via direct final rulemaking action, Delaware's Regulation No. 45, entitled “Excessive Idling of Heavy Duty Vehicles,” and is incorporating this rule into the Delaware SIP.

III. Why Is EPA Approving Delaware's SIP Revision?

Delaware Regulation No. 45 results in reduced emissions of pollutants that contribute to nonattainment of National Ambient Air Quality Standards for ozone and fine particulate matter. Specifically Regulation 45 leads to elimination of such pollutants resulting from unnecessary extended idling of heavy-duty vehicles. The pollutants reduced by this regulation are volatile organic compounds and nitrogen oxides, both of which are ground level ozone pollution precursors. Delaware's rule will also reduce emissions of carbon monoxide, fine particulate matter, and the greenhouse gas carbon dioxide.

The approval of Delaware's Regulation No. 45 will strengthen the Delaware SIP and assist the state in meeting and maintaining compliance with air quality standards, including the national ambient air quality standards for ground level ozone and fine particulate matter.

Delaware's Regulation No. 45 is generally consistent with EPA's “Model State Idling Law” (EPA420-S-06-001, April 2006). This model rule was developed with input from the states and affected industry to address extended idling issues in a consistent manner from state to state and to aid those being regulated in compliance with compliance with idling limits. Although Delaware's excessive idling regulation was adopted in 2005, prior to EPA's issuance of its model state idling rule, Delaware captured the major elements of the EPA model rule in its regulation.

IV. Final Action

EPA is approving Delaware's Air Quality Management Regulation No. 45, entitled “Excessive Idling of Heavy Duty Vehicles,” and incorporating this rule into the Delaware SIP. The rule is intended to reduce unnecessary idling from heavy duty motor vehicle engines within the boundaries of the state of Delaware.

EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comment. Similar provisions for reduced idling have been adopted in other states, and Delaware's regulation has been in place since 2005. Further, Delaware's Regulation No. 45 follows the spirit of EPA's model state idling rule, so we anticipate the regulated parties will understand Delaware's requirements as they relate to other nearby states and localities with similar excessive idling limits. However, in the “Proposed Rules” section of today's Federal Register, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision if adverse comments are filed. This rule will be effective on December 7, 2009 without further notice unless EPA receives adverse comment by November 9, 2009. If EPA receives adverse comment, EPA will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. EPA will address all public comments in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

V. Statutory and Executive Order Reviews

A. General Requirements

Under the Clean Air Act, 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); Start Printed Page 5179440 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 Clean Air Act. 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 seq.);
  • 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 application of those requirements would be inconsistent with the Clean Air Act; 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.

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 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).

C. Petitions for Judicial Review

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 7, 2009. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today's Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action to approve Delaware's SIP revision to reduce unnecessary idling of heavy-duty vehicles may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
