SUPPLEMENTARY INFORMATION:

I. CARB's TRU Authorization Request

CARB's December 29, 2022, letter to the EPA Administrator notified the EPA that CARB had amended its In-Use Diesel-Fueled Transport Refrigeration Units (TRU) and TRU Generator Sets (collectively, “TRU”) regulations (the TRU Amendments).^[1] The TRU Amendments, adopted by the Board on February 24, 2022, contain several provisions including, but not limited to, a requirement that certain TRUs manufactured after a certain date use a refrigerant less than or equal to a specified global warming potential (GWP), a requirement that non-truck TRUs meet specified particulate matter (PM) standards, a requirement that TRU owners transition a percentage of their truck fleet TRUs to zero-emission technology, and a requirement that owners of certain facilities are subject to registration and reporting requirements.^[2]

II. CARB's Offroad Fleets Authorization Request

CARB's November 2, 2023, letter to the EPA Administrator notified the EPA that CARB had amended its In-Use Off-Road Diesel-Fueled Fleets regulations (Offroad Fleets Amendments).^[3] The Offroad Fleets Amendments, adopted by the Board on December 8, 2022, primarily require fleets of in-use off-road diesel-fueled vehicles to phase out the operation of their oldest and highest-emitting diesel vehicles and prohibit such fleets from acquiring high-emitting vehicles. The Offroad Fleets Amendments also require fleets to fuel their vehicles with specified renewable diesel. Further, the Amendments establish administrative requirements for prime contractors and public works awarding bodies.^[4]

III. Scope of Preemption and Criteria for an Authorization Under the Clean Air Act

Section 209(e)(1) of the CAA prohibits all states and local governments from adopting or attempting to enforce any standard or other requirement relating to the control of emissions from certain types of new nonroad engines or nonroad vehicles, including both “(A) New engines which are used in construction equipment or vehicles or used in farm equipment or vehicles and which are smaller than 175 horsepower” and “(B) New locomotives or new engines used in locomotives.” ^[5] Section 209(e)(2)(A) of the CAA, however, requires the Administrator, after notice and opportunity for public hearing, to authorize California to adopt and enforce standards and other requirements relating to the control of emissions from nonroad engines and vehicles otherwise not prohibited under section 209(e)(1) if California determines that California standards will be, in the aggregate, at least as protective of public health and welfare as are applicable Federal standards. However, the EPA shall not grant such authorization if it finds that (1) the determination of California is arbitrary and capricious; (2) California does not need such California standards to meet compelling and extraordinary conditions; or (3) California standards and accompanying enforcement procedures are not consistent with [CAA section 209].^[6]

On July 20, 1994, the EPA promulgated a rule that sets forth, among other things, regulations providing the criteria, as found in section 209(e)(2)(A), that the EPA must consider before granting any California authorization request for nonroad engine or vehicle emission standards.^[7] The EPA revised these regulations in 1997.^[8] The criteria for granting California authorization requests, as reflected in section 209(e)(2)(A), can be found at 40 CFR 1074.105.

As stated in the preamble to the 1994 rule, the EPA has historically interpreted the section 209(e)(2)(A)(iii) “consistency” inquiry (see 40 CFR 1074.105(b)(3)) 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 the EPA has interpreted that subsection in the context of section 209(b) motor vehicle waivers).^[9]

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 (such as “. . . any standard or other requirement relating to the control of emissions from . . . (A) New engines which are used in construction equipments or vehicles or used in farm equipment or vehicles and which are smaller than 175 horsepower. (B) New locomotives or new engines used in locomotives.”).

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 he 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.^[10]

III. EPA's Request for Comments

We request comment on whether the TRU Amendments meet the criteria for an EPA authorization. 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. As explained above, the EPA considers several provisions with regard to the consistency with section 209 of the Act criterion.

We also request comment on whether the Offroad Fleets Amendments meet the criteria for an EPA authorization. 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. As explained above, the EPA considers several provisions with regard to the consistency with section 209 of the Act criterion.

The EPA does not intend to publish a document in the Federal Register announcing updates.

Each commenter will have 3 minutes to provide oral testimony. The EPA may ask clarifying questions during the oral presentations but will not respond to the presentations at that time. The EPA recommends submitting the text of your oral comments as written comments to the docket for the respective authorization request. Written statements and supporting information submitted during the comment period will be considered with the same weight as oral comments and supporting information presented at the public hearing for the respective authorization request. The Agency will make a verbatim record of the proceedings at each hearing that will be placed in the respective TRU and Offroad Fleets dockets. The EPA will keep the record open until June 19, 2024, for each authorization request. After expiration of the comment period, the Administrator will render decisions on CARB's requests based on the record of the public hearing, relevant written submissions, and other information that he deems pertinent.
