Environment (Waste Management)

This bill extends the authorization for a uranium mill tailings disposal site in Mesa County, Colorado, until the site is filled to its designed capacity. It directly affects the facility operators and local communities by allowing them to continue using the site for waste disposal beyond the current expiration date. The legislation amends the Uranium Mill Tailings Radiation Control Act of 1978 to remove the previous September 30, 2031 deadline, replacing it with a condition based on the site reaching its intended capacity. This change provides regulatory certainty for ongoing operations at the disposal facility.

Mining Regulatory Clarity Act This bill allows mining operators to use federal lands for activities ancillary to mining, such as waste disposal, regardless of whether those lands contain mineral deposits valuable enough to be mined (mineral validity). It also establishes the Abandoned Hardrock Mine Fund. The bill addresses a 2022 decision in the U.S. Court of Appeals for the Ninth Circuit related to the Rosemont Copper Mine in Arizona (commonly known as the Rosemont decision , described further in CRS Report R48166 ). The court held that mining claims are only allowed where mineral validity has been established and that mill site claims are more appropriate means for establishing a mining waste disposal site under the Mining Act. The bill allows a mining operator to (1) locate and include within its plan of operations as many mill site claims (e.g., areas for waste rock disposal) as are reasonably necessary for its operations, and (2) use or occupy public land in accordance with an approved plan of operations. Additionally, the bill requires any revenue generated from fees for such mill site claims to be deposited into the Abandoned Hardrock Mine Fund. The Department of the Interior must use the fund for certain abandoned hardrock mine reclamation activities.

HR 3059, the Streamlining Critical Mineral Permitting Act, modifies the Solid Waste Disposal Act to create a new pathway for temporary hazardous waste permits. It directly affects mining and processing facilities handling "critical energy resources" (defined as energy resources essential to U.S. energy systems with vulnerable supply chains, as determined by the Energy Secretary). The bill adds a new category allowing these "critical energy resource facilities" to qualify for interim hazardous waste permits under Section 3005(e). This aims to expedite permitting for facilities processing minerals critical to clean energy and national security, without changing existing environmental standards.

HR 3346 would eliminate the federal Environmental Protection Agency (EPA) 270 days after the bill becomes law, transferring its environmental responsibilities to state and territorial agencies. The bill allocates $4.4 billion annually (2026-2029) to states based on population for programs covering air/water quality, waste management, chemical safety, and contaminated site cleanup. States must designate a specific environmental department to manage funds, undergo audits, and repay misused funds. This directly affects all 50 states, the District of Columbia, and U.S. territories by replacing federal oversight with state-administered environmental programs.

This bill exempts facilities recycling spent petroleum catalyst for metal recovery (like vanadium) from certain waste regulations under the Solid Waste Disposal Act. It specifically removes the requirement for these facilities to comply with Boilers and Industrial Furnaces (BIF) rules, applying to thermal treatment units (e.g., roasters) and metallurgical units (e.g., furnaces) that process catalyst into intermediate products or recover metals. The exemption covers spent hydrotreating and hydrorefining catalyst (EPA hazardous wastes K171/K172) and allows third-party transfer for recycling. This aims to streamline domestic recovery of critical minerals - such as vanadium used in steel for defense and infrastructure - without adding new environmental regulations, as current air permits already enforce safeguards.

This bill amends the Clean Air Act to clarify when certain plastic conversion facilities are excluded from the definition of "solid waste incineration units." It directly affects companies operating facilities that transform plastic or post-use polymers (via methods like pyrolysis) into usable materials, provided at least 50% of the output by mass is a "product" (e.g., usable substances for sale or manufacturing), not energy or ash. Key mechanisms include adding a specific exclusion for qualifying conversion units (Section 2(A)(iv)) and creating a 180-day petition process for other similar units to seek exclusion (Section 2(B)). The bill defines "product" to exclude electricity, heat, or ash but include materials with commercial applications.

This bill exempts specific metal recovery processes from certain waste regulations. It clarifies that facilities recycling vanadium and other critical minerals from spent petroleum catalyst (used in oil refining) are not subject to the Boilers and Industrial Furnaces (BIF) requirements under the Solid Waste Disposal Act. The exemption covers the entire recycling chain: de-oiling, thermal treatment (e.g., roasting), and metallurgical recovery (e.g., furnaces). It also allows third-party transfers of spent catalyst for metals reclamation under existing transfer-based waste exclusions. This change aims to eliminate redundant regulations for environmentally safe domestic recovery of critical minerals like vanadium.

This joint resolution (SJRES 85) seeks congressional disapproval of an Environmental Protection Agency (EPA) rule that would have regulated temporary incinerators used for disaster recovery. The EPA rule (published August 26, 2025) addressed "Commercial and Industrial Solid Waste Incineration Units: Temporary-Use Incinerators and Air Curtain Incinerators Used in Disaster Recovery." If approved, the resolution would block the EPA rule from taking effect, meaning the rule would have no force or effect. The resolution directly affects the EPA's ability to implement this specific regulation for disaster waste management.
