[Docket No. EPA-HQ-OAR-2023-0216: FRL-10833-01-OAR]

Development of Guidance for Zero-Emission Clean Heavy-Duty 
Vehicles, Port Equipment, and Fueling Infrastructure Deployment Under 
the Inflation Reduction Act Funding Programs

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice; request for information (RFI).

-----------------------------------------------------------------------

SUMMARY: To support development of potentially multiple funding 
programs under the Inflation Reduction Act of 2022, EPA invites public 
comment to inform the availability of zero-emission technologies in the 
heavy-duty vehicle and port sectors. Although EPA already has 
considerable information about the availability of certain types of 
these technologies, in order to ensure that EPA has the most 
comprehensive and current information available in this dynamic space, 
EPA is inviting this comment. EPA is especially interested in comments 
detailing the availability, market price, and performance of zero-
emission trucks, zero-emission port equipment, electric charging and 
other fueling infrastructure needs for zero-emission technologies in 
the near term (1-3 years, and 1-5 years for port equipment), and 
whether the components of these systems are manufactured in the United 
States. The Build America Buy America Act (BABA) requires iron, steel, 
manufactured products, and construction materials used in 
infrastructure projects funded by federal financial assistance to be 
produced in the United States. While BABA provides the opportunity for 
EPA to issue certain waivers to these requirements, approval depends on 
many factors, including the price and availability of domestically 
sourced materials and products. With responses to this RFI EPA seeks to 
improve in particular the Agency's understanding of availability and 
differences in zero-emission class 6 and 7 trucks, zero-emission trucks 
that serve ports and port equipment as well as their related charging 
and fueling infrastructure requirements. This information will enable 
EPA to effectively design programs to expeditiously fund currently 
available zero-emission technologies as well as consider allowances, 
such as longer project timeframes, for specific technologies.

DATES: Comments must be received on or before June 5, 2023, to allow 
for their consideration during development of these funding programs. 
EPA may consider comments received after the due date to the extent 
practicable.

specifically designated as CBI will be placed in the public docket for 
this matter.

Background

    In this section the Agency provides background information on two 
programs in the Inflation Reduction Act (IRA). The IRA enacted as 
Public Law 117-169 (August 16, 2022), includes important new programs 
to address climate change by reducing greenhouse gas emissions and to 
improve air quality through use of zero-emission vehicles and 
equipment. Among these programs is a (1) Clean Heavy-Duty Vehicles 
Program, and (2) Grants to Reduce Air Pollution at Ports Program. These 
programs provide funding that EPA will distribute to eligible 
recipients.
    The Clean Heavy-Duty Vehicles (HDV) Program directs the 
Administrator to make awards of grants and rebates to eligible 
recipients and to make contracts to eligible contractors for providing 
rebates ($1 billion total). Eligible recipients include states, 
municipalities, Indian Tribes, or nonprofit school transportation 
associations. Eligible contractor means a contractor that has the 
capacity; (A) to sell, lease, license, or contract for service zero-
emission vehicles, or charging or other equipment needed to charge, 
fuel, or maintain zero-emission vehicles, or to contract for service an 
eligible vehicle, or (B) to arrange financing for such a sale, lease, 
license, or contract for service. Funding can be for up to 100% of the 
costs for (1) the incremental costs of replacing an eligible class 6 or 
7 heavy-duty vehicle with a zero-emission vehicle (2) purchasing, 
installing, operating and maintaining infrastructure needed to charge, 
fuel or maintain zero-emission vehicles; (3) workforce development and 
training to support the maintenance, charging, fueling and operation of 
zero-emission vehicles; and (4) planning and technical activities to 
support the adoption and deployment of zero-emission vehicles.
    The Grants to Reduce Air Pollution at Ports Program (hereafter 
``Clean Ports Program'') provides the Administrator funding to award 
rebates and grants to eligible recipients on a competitive basis ($3 
billion total). Rebate and grant funding may be used: (A) to purchase 
or install zero-emission port equipment or technology for use at or to 
directly serve, one or more ports; (B) to conduct any relevant planning 
or permitting in connection with the purchase or installation of such 
zero-emission port equipment or technology; and (C) to develop 
qualified climate action plans. Eligible recipients include: (A) a port 
authority; (B) a state, regional, local or Tribal Agency that has 
jurisdiction over a port authority or a port; (C) an air pollution 
control agency; or (D) a private entity that (i) applies for a grant in 
partnership with an entity described in (A) through (C) and (ii) and 
owns, operates, or uses the facilities, cargo-handling equipment, 
transportation equipment or related technology of a port. Zero-emission 
port equipment or technology means a human-operated equipment or human-
maintained technology that; (A) produces zero emissions of any air 
pollutant or any greenhouse gas other than water vapor; or (B) captures 
100 percent of the emissions produced by an ocean-going vessel at 
berth.
    Zero-emission vehicles and equipment are increasingly being offered 
for sale in the commercial truck and ports markets. Current options 
include vehicles powered by electricity and hydrogen. The Agency is 
aware of many of these product offerings. However, given the wide range 
of potential vehicles and equipment that could be considered for 
funding under the Clean HDV and Clean Ports Programs, EPA believes it 
is critical to provide an opportunity for all stakeholders (e.g., 
manufacturers, distributors, installers, fleet operators, port 
operators) to share information about their products and firsthand 
experience with zero-emission technologies if they so choose, in order

[[Page 29668]]

to give EPA the broadest understanding possible of potential vehicles 
and equipment eligible to fund.
    Charging and Fueling Infrastructure: Through the Clean HDV and 
Clean Ports programs, EPA may fund charging and other fueling 
infrastructure as an eligible expense in supporting zero-emission 
heavy-duty vehicle and port equipment projects. To this end, the Agency 
seeks information on the manufacturing and assembly of electric 
charging and other fueling infrastructure for zero-emission commercial 
vehicles and port equipment, such as whether zero-emissions fueling 
infrastructure manufactured in the United States can comply with 
applicable BABA requirements. This RFI is intended to: (A) help EPA 
better understand whether and to what extent domestic sourcing is 
available now, or may be possible in the near future, for electric 
charging and other fueling equipment and components; (B) ensure 
domestic manufacturers have the opportunity to identify any electric 
vehicle (EV) charger and fueling equipment meeting applicable BABA 
requirements; (C) ensure domestic manufacturers have the opportunity to 
identify any electric charging and other fueling equipment that could 
meet a domestic final assembly condition, and identify the portion of 
components that could meet a domestic manufacturing requirements; and 
(D) highlight benefits of shifting manufacturing processes to the 
United States.
    Through this RFI, EPA seeks information regarding the availability 
of zero-emission heavy-duty vehicle and port equipment, electric 
chargers and fueling equipment, such as for hydrogen, that is 
manufactured and/or assembled in the United States, including whether 
they comply with applicable BABA requirements. EPA is not aware of any 
zero-emission heavy-duty vehicle or port equipment electric chargers or 
fueling equipment that currently meets applicable BABA requirements for 
steel and iron or manufactured products. The Agency is interested in 
promptly obtaining more information on this issue and others discussed 
in this notice to assess if sufficient quantities of equipment are 
currently available to comply with BABA requirements or whether 
sufficient equipment would be available in the near future.

Build America Buy America Act

    In January 2021, the President issued Executive Order (E.O.) 14005, 
titled ``Ensuring the Future is Made in All of America by All of 
America's Workers.'' 86 FR 7475 (Jan. 28, 2021). E.O. 14005 states that 
the United States Government ``should, consistent with applicable law, 
use terms and conditions of Federal financial assistance awards and 
Federal procurements to maximize the use of goods, products, and 
materials produced in, and services offered in, the United States.'' 
The EPA is committed to ensuring strong and effective Buy America 
implementation consistent with E.O. 14005. At the same time, the EPA 
must also consider how to ensure that electric chargers and fueling 
equipment, such as for hydrogen, are widely available in the immediate 
future to implement EPA-funded projects throughout the United States 
and its territories in a timely and cost-effective manner.
    On November 15, 2021, President Biden signed into law the 
Infrastructure Investment and Jobs Act (``IIJA''), Public Law 117-58, 
which includes the Build America, Buy America (BABA) Act. Public Law 
117-58, sections 70901-52. The Act strengthens Made in America Laws and 
will bolster America's industrial base, protect national security, and 
support high-paying jobs. The Act requires that the head of each 
covered Federal agency ensure that ``none of the funds made available 
for a Federal financial assistance program for infrastructure, 
including each deficient program, may be obligated for a project unless 
all of the iron, steel, manufactured products, and construction 
materials used in the project are produced in the United States'' 
(Build America, Buy America (BABA) Act, Pub. L. 117-58, Sections 70911-
70917), unless a waiver is granted.\1\ This means that the manufactured 
product was manufactured in the United States, and the cost of the 
components of the manufactured product that are mined, produced, or 
manufactured in the United States is greater than 55 percent of the 
total cost of all components of the manufactured product, unless 
another standard for determining the minimum amount of domestic content 
of the manufactured product has been established under applicable law 
or regulation. IIJA section 70912(6)(B). For all steel or iron 
materials used in infrastructure projects that involve the obligation 
of federal financial assistance, manufacturing processes, including 
application of a coating, must occur in the United States. Coating 
includes all processes which protect or enhance the value of the 
material to which the coating is applied. Such projects involve both 
the acquisition and installation of such equipment. These requirements 
apply to the obligation of all federal financial assistance for 
infrastructure projects, including IRA funds. EPA is committed to 
ensuring strong and effective Buy America implementation consistent 
with E.O. 14005. In implementing the IRA Clean HDV and Ports Programs, 
EPA will ensure compliance with BABA requirements.
