Notice of opportunity for public hearing and comment.


The California Air Resources Board (CARB) has notified EPA that it has adopted regulations for the control of emissions of particulate matter and oxides of nitrogen from new and in-use diesel-fueled engines on commercial harbor craft. CARB has requested that EPA issue a new authorization under section 209(e) of the Clean Air Act for the emission standards established by these regulations. This notice announces that EPA has tentatively scheduled a public hearing to consider California's authorization request, and that EPA is now accepting written comments on the request.


EPA has tentatively scheduled a public hearing concerning CARB's request for July 21, 2011, at 1 p.m. EST. EPA will hold a hearing only if any party notifies EPA by July 15, 2011, expressing its interest in presenting oral testimony. Parties wishing to present oral testimony at the public hearing should provide written notice to Kristien Knapp at the e-mail address noted below. If EPA receives a request for a public hearing, that hearing will be held at 1310 L Street, NW., Washington, DC 20005. If EPA does not receive a request for a public hearing, then EPA will not hold a hearing, and will instead consider CARB's request based on written submissions to the docket. Any party may submit written comments until August 22, 2011.

By July 20, 2011, any person who plans to attend the hearing may call Tayyaba Waqar at (202) 343-9182, to learn if a hearing will be held.

I. California's Commercial Harbor Craft Regulations

In a letter dated April 12, 2010, CARB submitted to EPA its request pursuant to section 209(e) of the Clean Air Act (“CAA” or “the Act”), regarding its regulations to enforce emission standards for new and in-use commercial harbor craft operated within California waters and twenty-four nautical miles of the California baseline (“commercial harbor craft regulations” or “CHC regulations”).[1] The CARB Board approved the commercial harbor craft regulations at its November 15, 2007 hearing (by Resolution 07-47).[2] After making modifications, as directed by the Board, CARB's Executive Officer formally adopted the rulemaking in Executive Order R-08-007 on September 2, 2008.[3] CARB's commercial harbor craft regulations became operative under California state law on November 19, 2008.[4] The regulations are codified in title 13, California Code of Regulations (CCR), section 2229.5 and title 17, CCR section 93118.5.[5] California's commercial harbor craft regulations establish emission standards; requirements related to the control of emissions; and enforcement provisions. The requirements are applicable to diesel propulsion and auxiliary engines on new and in-use commercial harbor crafts, with some exceptions.[6] Commercial harbor craft include a variety of different types of vessels, including ferries, excursion vessels, tugboats, towboats, and commercial and charter fishing boats. Approximately eighty percent of commercial harbor craft engines operating in California are previously unregulated diesel engines, accounting for approximately 3.3 tons per day (tpd) of diesel particulate matter (PM) and 73 tpd of oxides of nitrogen (NOX). California's commercial harbor craft regulations aim to reduce these emissions so that California can meet the 2014 National Ambient Air Quality Standards (NAAQS) deadline for PM2.5 in the South Coast Air Basin. The commercial harbor craft regulations apply separately to new and in-use engines used on harbor craft.[7]

For new harbor crafts, each propulsion and auxiliary diesel engine on the vessel is required to be certified to the most stringent federal new marine engine emissions standards for that engine's power rating and displacement in effect at the time of sale, lease, rent, or acquisition. The regulation imposes additional requirements for larger new ferries (with the capacity to transport seventy-five or more passengers), either by using best available control technology (“BACT”),[8] or by using a federal Tier 4 certified propulsion engine.

For in-use harbor craft, newly acquired new or in-use harbor craft may not be sold, offered for sale, leased, rented, or acquired unless the diesel propulsion or auxiliary engines are certified to at least the federal Tier 2 or Tier 3 marine emission standards for new engines of the same power rating and displacement. In-use emission requirements are imposed on Tier 0 and Tier 1 marine engines in ferries, excursion vessels, tugboats, towboats, push boats, and multipurpose harbor craft. Those harbor crafts are required to meet emission limits equal to or cleaner than the federal new marine engine certification standards in effect for the year that in-use engine compliance is required.

California's commercial harbor craft regulations also impose requirements related to monitoring, reporting and recordkeeping of compliance on owners and operators of new and in-use harbor craft. Subject to CARB approval, harbor craft owners and operators may opt to meet requirements by implementing alternative emission control strategies.[9]

II. Clean Air Act Nonroad Engine and Vehicle Authorizations

Section 209(e)(1) of the Act permanently preempts any State, or political subdivision thereof, from Start Printed Page 38155adopting or attempting to enforce any standard or other requirement relating to the control of emissions for certain new nonroad engines or vehicles. Section 209(e)(2) requires the Administrator, after notice and opportunity for public hearing, to authorize California to enforce standards and other requirements relating to the control of emissions from new engines not listed under section 209(e)(1), if certain criteria are met. EPA has promulgated regulations implementing these provisions at 40 CFR part 1074. These regulations set forth the criteria that EPA must consider before granting California authorization to enforce its new nonroad emission standards.[10] As stated in the preamble to the section 209(e) rule, EPA has historically interpreted the section 209(e)(2)(iii) “consistency” inquiry to require, at minimum, that California standards and enforcement procedures be consistent with section 209(a), section 209(e)(1), and section 209(b)(1)(C) (as EPA has interpreted that subsection in the context of section 209(b) motor vehicle waivers).[11]

In order to be consistent with section 209(a), California's nonroad standards and enforcement procedures must not apply to new motor vehicles or new motor vehicle engines. To be consistent with section 209(e)(1), California's nonroad standards and enforcement procedures must not attempt to regulate engine categories that are permanently preempted from state regulation. To determine consistency with section 209(b)(1)(C), EPA typically reviews nonroad authorization requests under the same “consistency” criteria that are applied to motor vehicle waiver requests. Pursuant to section 209(b)(1)(C), the Administrator shall not grant California a motor vehicle waiver if she finds that California “standards and accompanying enforcement procedures are not consistent with section 202(a)” of the Act. Previous decisions granting waivers and authorizations have noted that state standards and enforcement procedures are inconsistent with section 202(a) if: (1) There is inadequate lead time to permit the development of the necessary technology giving appropriate consideration to the cost of compliance within that time, or (2) the federal and state testing procedures impose inconsistent certification requirements.

III. EPA's Request for Comments

As stated above, EPA is offering the opportunity for a public hearing, and requesting written comment on issues relevant to a full section 209(e) authorization analysis. Specifically, we request comment on: (a) Whether CARB's determination that its standards, in the aggregate, are at least as protective of public health and welfare as applicable federal standards is arbitrary and capricious, (b) whether California needs such standards to meet compelling and extraordinary conditions, and (c) whether California's standards and accompanying enforcement procedures are consistent with section 209 of the Act.

IV. Procedures for Public Participation

If a hearing is held, the Agency will make a verbatim record of the proceedings. Interested parties may arrange with the reporter at the hearing to obtain a copy of the transcript at their own expense. Regardless of whether a public hearing is held, EPA will keep the record open until August 22, 2011. Upon expiration of the comment period, the Administrator will render a decision on CARB's request based on the record from the public hearing, if any, all relevant written submissions, and other information that she deems pertinent. All information will be available for inspection at the EPA Air Docket No. EPA-HQ-OAR-2011-0549.

Persons with comments containing proprietary information must distinguish such information from other comments to the greatest extent possible and label it as “Confidential Business Information” (“CBI”). If a person making comments wants EPA to base its decision on a submission labeled as CBI, then a non-confidential version of the document that summarizes the key data or information should be submitted to the public docket. To ensure that proprietary information is not inadvertently placed in the public docket, submissions containing such information should be sent directly to the contact person listed above and not to the public docket. Information covered by a claim of confidentiality will be disclosed by EPA only to the extent allowed, and according to the procedures set forth in 40 CFR part 2. If no claim of confidentiality accompanies the submission when EPA receives it, EPA will make it available to the public without further notice to the person making comments.

8.  BACT is the diesel emission control strategy (DECS) determined by CARB to be the greatest feasible reduction of NOX or PM when used with the ferry's propulsion engines and does not result in an increase of ten percent or more of any air pollutant including NOX or PM, relative to the engine's emission of that air pollutant without the use of BACT and use of DECS on or with engine does not invalidate or otherwise adversely affect the propulsion engine's original warranty.
