Proposed rule.


The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan revision submitted by New Jersey to revise its rules regarding the idling of diesel-powered vehicles. Specifically, the State's implementation plan revision revises the exceptions to and exemptions from the State's existing three-minute idling rule. The intended effect of this action is to approve, as consistent with section 110(a)(2) of the Clean Air Act, a control strategy that will help New Jersey achieve attainment of the National Ambient Air Quality Standards for ozone and fine particulate matter.

I. Description of the State Implementation Plan (SIP) Revision

A. What did New Jersey submit?

On July 2, 2007, New Jersey promulgated amendments to Title 7, Chapter 27, Subchapter 14, “Control and Prohibition of Air Pollution from Diesel-Powered Motor Vehicles,” of the New Jersey Administrative Code, that limits the amount of time that engines of diesel-powered motor vehicles may idle. New Jersey's original diesel idling rule, adopted on December 2, 1985, prohibits any person from allowing the engine of a diesel-powered motor vehicle to idle for more than three consecutive minutes. However, it also provides exceptions to and exemptions from the three-minute limit. New Jersey's July 2007 rule revision adds, deletes, and revises certain exceptions and exemptions, with the overall goal of further limiting air emissions from idling diesel-powered vehicles within New Jersey. This revised rule became operative on July 25, 2007. On September 13, 2007, New Jersey submitted its revised diesel idling rule to EPA for approval as a SIP revision.

New Jersey's original diesel idling rule provided two exceptions to the three-minute limit: When at an operator's place of business, a diesel vehicle was allowed to idle for up to 30 minutes; and when a diesel vehicle's engine had been stopped for three or more hours, the vehicle was allowed to idle for up to 15 minutes. New Jersey's revised rule deletes the first exception and revises the second, so that the 15-minute limit only applies when the ambient temperature is below 25 degrees Fahrenheit. In addition, New Jersey adopted a new exception, to allow a diesel bus that is actively discharging or picking up passengers to idle for 15 consecutive minutes in a 60-minute period.

New Jersey's rule also initially contained eight exemptions to the three-minute idling limit. Diesel vehicles were exempt from the three-minute limit when engaged in the following: discharging or picking up passengers; idling in traffic; idling to provide power to auxiliary equipment (except heating or air conditioning systems); idling while being or waiting to be examined by a motor vehicle inspector; actively performing emergency services; undergoing repair or service; connecting or detaching trailers; or, for diesel vehicles equipped with sleeper berths, while the sleeper berth was being used for rest, unless the vehicle had an auxiliary power system to maintain cabin comfort or assist with cold-weather starting.

In its revised rule, New Jersey removed the exemption for picking up and discharging passengers, replacing it with a 15-minute idling limit (see above), and removed the exemption for connecting or detaching trailers. New Jersey also clarified that a diesel vehicle being repaired or serviced may idle only if operation of the engine is essential to the repair or service being performed. New Jersey is also limiting the sleeper berth exemption by removing this exemption for any vehicle not equipped with either a 2007 or newer engine or an older engine retrofitted with a properly functioning diesel particulate filter. The revised sleeper berth exemption becomes effective on May 1, 2010. However, the Commissioner of the New Jersey Department of Environmental Protection may delay the effective date of this revised exemption for up to one year, if it is determined that public safety would be adversely affected if the exemption were to take effect on May 1, 2010. Finally, New Jersey adopted a new exemption allowing technologies designed to reduce idling (such as auxiliary power units, generator sets, or bunk heaters) to operate provided the diesel vehicle's main engine is not idling.

In addition to the new and revised exemptions, New Jersey adopted a new provision prohibiting a diesel vehicle from idling for more than three minutes when parked in a space with available electrification technology, which is defined as “* * * a technology that harnesses an off-vehicle electrical system to provide a vehicle with climate control and other needs.” There are no exemptions from this provision.

B. What is EPA's evaluation of New Jersey's SIP revision submittal?

EPA has evaluated New Jersey's SIP revision submittal (described above), including the comments and responses New Jersey received during its public process. EPA has determined that New Jersey adequately addressed the Start Printed Page 57274comments received and that New Jersey's revised diesel idling rule is enforceable and approvable as a control strategy to attain and maintain the national ambient air quality standards, as consistent with section 110(a)(2) of the Clean Air Act, 42 U.S.C. 7410(a)(2).

II. Proposed EPA Action

EPA is proposing to approve the revisions to New Jersey's diesel idling rule as part of New Jersey's ozone and particulate matter SIPs.

III. Statutory and Executive Order Reviews

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); 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 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 (Public Law 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.
