Padilla, Cortez Masto Call on Treasury and IRS to Expand Access to Vehicle Refueling Infrastructure Credits

WASHINGTON, D.C. — Today, U.S. Senators Alex Padilla (D-Calif.) and Catherine Cortez Masto (D-Nev.) led 13 Senators in calling on the Department of the Treasury and the Internal Revenue Service (IRS) to finalize guidance for and maximize inclusive access to the 30C Alternative Fuel Vehicle Refueling Property Credit. The Inflation Reduction Act (IRA) included an extension of this tax credit, which provides billions of dollars for eligible refueling infrastructure investments such as zero-emission truck stops, intermodal facilities, and warehouses.

Compared to a more restrictive threshold, the recommendations of the letter would expand eligibility to cover an estimated 32 million additional people, including 4.7 million rural residents, 2.1 million people living in poverty, 2.2 million Black people, and 3.6 million Latinos.

The letter also requests that Treasury Secretary Janet Yellen and IRS commissioner Daniel Werfel adopt temporary safe harbor conditions in their guidance to protect taxpayers who already installed infrastructure over the last year and to minimize negative impacts on future investment and planning decisions. 

“Effective implementation of Section 30C is critical to realizing the Administration’s goal of deploying 500,000 chargers by 2030 and facilitating the swift decarbonization of our transportation sector,” wrote the Senators. 

In addition to Senators Padilla and Cortez Masto, the letter is signed by Senators Tom Carper (D-Del.), Ben Cardin (D-Md.), Martin Heinrich (D-N.M), Mazie Hirono (D-Hawaii), Tim Kaine (D-Va.), Edward J. Markey (D-Mass.), Jeff Merkley (D-Ore.), Gary Peters (D-Mich.), Jacky Rosen (D-Nev.), Bernie Sanders (I-Vt.), Debbie Stabenow (D-Mich.), Chris Van Hollen (D-Md.), and Peter Welch (D-Vt.).

Senator Padilla has consistently fought for emissions reductions in the transportation sector. This letter follows an effort Padilla spearheaded in October, leading 14 Senators to call on the Joint Office of Energy and Transportation to prioritize the deployment of zero-emission medium- and heavy-duty infrastructure as part of its core mission. That letter included a request for the Joint Office to urge the IRS to finalize guidance on the 30C tax credit and define “urban area” in line with the language included in today’s letter.

Last month Padilla, Senator Sheldon Whitehouse (D-R.I.) and leaders from the heavy-duty vehicle industry called on the Environmental Protection Agency (EPA) to finalize the strongest possible Phase 3 heavy-duty vehicles emissions rule by early 2024. He has also led a series of letters advocating for strong vehicle greenhouse gas emissions standards, including for heavy-duty trucks.

Full text of the letter is available here and below:

Dear Secretary Yellen and Commissioner Werfel:

We write to urge you to swiftly finalize guidance for the Section 30C Alternative Fuel Vehicle Refueling Property Credit, which was significantly expanded through the historic Inflation Reduction Act (IRA, P.L. 117-169). We also ask that you, in this guidance, establish an inclusive census tract definition, clarify per single item basis, and provide a safe harbor provision for certain investments already made. Effective implementation of Section 30C is critical to realizing the Administration’s goal of deploying 500,000 chargers by 2030 and facilitating the swift decarbonization of our transportation sector.

As you know, to qualify under Section 30C, the IRA requires properties to be placed in service in an “eligible census tract,” which excludes “urban areas” as designated by the Secretary of Commerce. We urge you to define eligible census tracts in the most inclusive manner possible. Specifically, we advocate for making eligible any and all census tracts in which no less than 10 percent of census blocks are classified as rural, consistent with the recommendations endorsed by a coalition of more than 30 environmental, industry, consumer, and labor stakeholders in June. The interpretation will incentivize significant additional public and private sector investments in zero-emission truck stops, intermodal facilities, warehouses, and other foundational locations, as Congress intended.

Additionally, the IRA amended Section 30C to provide incentives on a per single item basis rather than a per location basis, dramatically increasing the availability of the credit and better aligning this important investment in the Nation’s charging infrastructure with current and future technologies. We urge that each port at a refueling property be considered a single item, consistent with the Department of Transportation’s National Electric Vehicle Infrastructure program. This will provide flexibility as refueling properties increase in size and capabilities, improving longevity and enabling future innovation.

Given the delays and uncertainty created by the current lack of guidance, we encourage the adoption of a temporary safe harbor for taxpayers who have acted in good faith to comply with Section 30C requirements. This should also be accompanied with the development and dissemination of maps and other user-friendly materials or tools to help navigate eligibility. Such actions will protect taxpayers who installed infrastructure over the last year and minimize negative impacts on future investment and planning decisions.

We appreciate your attention to this matter, and we look forward to working with you to ensure that federal investments are consistent with the Administration’s broader climate and environmental justice goals.
