This legislation, known as the CLEANER Act of 2025 , aims to eliminate regulatory exemptions for wastes generated during the exploration, development, and production of crude oil, natural gas, and geothermal energy. It requires the Environmental Protection Agency (EPA) to bring these wastes under the purview of the Solid Waste Disposal Act (SWDA). Specifically, within one year of enactment, the EPA must assess whether drilling fluids, produced waters, and other associated wastes meet the criteria for hazardous waste. If determined to be hazardous, the EPA must identify or list them as such and promulgate regulations under Subtitle C of the SWDA, with the flexibility to modify requirements to account for their unique characteristics while ensuring environmental and human health protection. For wastes not classified as hazardous, the bill mandates the EPA to revise Subtitle D criteria for facilities receiving these wastes. These revised criteria must protect human health and the environment, including requirements for groundwater monitoring, acceptable facility locations, corrective action, and financial assurance.
