H.R.1: What You Should Know About the Environmental and Energy Provisions in the “One Big Beautiful Bill” Act
On July 4, President Trump signed H.R.1—the “One Big Beautiful Bill,” referred to as the OBBB—into law. This sweeping tax and policy law, enacted through the process of budget reconciliation requiring a simple majority vote by Congress, carries significant implications for environmental funding, clean energy development, and climate-related programs administered by the U.S. Environmental Protection Agency (EPA), as well as the tax code. Much of the provisions affect programs and funding originally authorized under the 2022 Inflation Reduction Act (“IRA”), which was former President Biden’s signature budget reconciliation bill. Below, we outline some of the key features of the OBBB environmental and energy provisions.

IRS Proposed Rule on Revived Superfund Chemical Taxes
On March 29, 2023, the U.S. Internal Revenue Service (IRS) published a Proposed Rule to amend the Environmental Tax Regulations, 25 C.F.R. part 52, specifically those provisions governing the chemical excise taxes used to fund the Hazardous Substance Response Trust Fund established pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)—known as the Superfund Chemical Tax. Because this is the first time the tax will be applied in over 25 years, its effects may not be well understood by affected industry taxpayers, and the IRS’s Proposed Rule offers critical guidance. Companies engaged in the manufacturing, import, or sale of taxable chemicals should evaluate the Proposed Rule and consider submitting comments by the May 30, 2023, deadline.
