NPDES Stormwater Exemption for Oil, Gas, and Mining Operations
Current understanding
Current Clean Water Act provisions prohibit EPA from requiring NPDES permits for stormwater runoff from oil and gas exploration, production, processing, treatment, or transmission operations, and comparable exemptions apply to certain mining stormwater discharges. The FRESHER Act of 2025 (introduced) proposes to eliminate this exemption and direct the Department of the Interior to study groundwater and aquifer contamination risks from such runoff. Practical effects would include new federal permitting obligations, compliance costs, and monitoring requirements for operators, with potential water-quality benefits and disputed effects on domestic production.
