Supplementary information:

I. California's ATCM for In-Use Portable Diesel Engines 50 Horsepower and Greater

In a letter dated December 5, 2006, CARB submitted to EPA its request pursuant to section 209 of the Clean Air Act (“CAA” or “the Act”), regarding its regulations to enforce its airborne toxic control measure (ATCM) for in-use portable diesel-fueled engines 50 brake-horsepower (hp) and greater (portable engines). [1] The authorization request covers four primary substantive requirements: (1) Starting January 1, 2010, all portable engines in the state must be certified to meet a Federal or California standard for newly manufactured nonroad engines, subject to specified exceptions; (2) Starting January 1, 2020, all portable engines in California must be either (a) certified to meet Tier 4 emission standards, (b) equipped with a properly functioning Level-3 verified technology, [2] or (c) equipped with a combination of control strategies that have been verified together to achieve at least an 85% reduction in diesel particulate matter (PM) emissions, subject to specified exceptions; (3) All portable engines that prior to January 1, 2006 have not been either registered in CARB's Portable Equipment Registration Program (PERP) or permitted under the permit program of an air quality management district or air pollution control district must meet the most stringent of the Federal or California emission standards for non-road engines at the time the engine is either registered in the PERP or registered for a permit, subject to specified exceptions; and (4) Each fleet of portable engines must comply with increasingly more stringent weighted PM emission fleet averages that apply on three different deadlines, (January 1, 2013, January 1, 2017 and January 1, 2020), subject to specified exceptions. [3]

Owners of in-use equipment will have options available to meet the CARB requirements. These include: purchasing new equipment with cleaner engines, repowering existing equipment with cleaner engines, using verified add-on control devices on existing equipment and engines, switching to alternative diesel fuels or alternative fuels, or electrifying some or all of the in-use fleet and receiving emission credits.

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 adopting 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 requirementsrelating 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. [4]

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). [5]

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. Procedures for Public Participation

As stated above, EPA is offering the opportunity for a public hearing, and requesting written comment on issues relevant to a full 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.

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 March 24, 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-2011-0101.

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.

Dated: February 3, 2011. Lori Stewart,

Acting Director, Office of Transportation and Air Quality, Office of Air and Radiation.

Footnotes

1. Portable engines are engines that may be moved easily from location to location. The engines are used to power a variety of equipment, including pumps, ground support equipment at airports, cranes, oil-well drilling and workover rigs, power generators, dredging equipment rock crushing and screening equipment, welding equipment, woodchippers and compressors.

2. Level 3 PM control technology refers to a control technology that has been verified to achieve PM reductions of at least 85 percent under the CARB “Verification Procedure, Warranty and In-Use Compliance Requirements for In-Use Strategies to Control Emissions from Diesel Engines,” 13 California Code of Regulations (CCR) sections 2700-2710.

3. The ATCM contains a fifth substantive requirement that pertains to the fuels that may be used in in-use portable equipment engines, but this fuels requirement is not preempted by CAA section 209(e) and does not require an authorization.

4. Title 40 of the Code of Federal Regulations, part 1074.105 provides:

(a) The Administrator will grant the authorization if California determines that its standards will be, in the aggregate, at least as protective of public health and welfare as otherwise applicable Federal standards.

(b) The authorization will not be granted if the Administrator finds that any of the following are true:

(1) California's determination is arbitrary and capricious.

(2) California does not need such standards to meet compelling and extraordinary conditions.

(3) The California standards and accompanying enforcement procedures are not consistent with section 209 of the Act.

(c) In considering any request from California to authorize the state to adopt or enforce standards or other requirements relating to the control of emissions from new nonroad spark-ignition engines smaller than 50 horsepower, the Administrator will give appropriate consideration to safety factors (including the potential increased risk of burn or fire) associated with compliance with the California standard.
