CLEAN UP Mines Act of 2026

The CLEAN UP Mines Act of 2026 modifies existing federal laws to tighten environmental and reclamation requirements for coal mining operations. It mandates that mines complete specific cleanup tasks, such as backfilling and grading, within 180 days after production stops and requires operators to submit plans to resume mining within a year if operations remain inactive for over six months. The bill also increases the frequency of government oversight by requiring quarterly water monitoring and annual biological assessments of streams. Additionally, it shortens the time allowed for releasing performance bonds from 60 days to 40 days, ensuring funds remain available to cover reclamation costs until work is fully completed. These changes directly affect coal mine operators and the regulatory agencies responsible for enforcing mining standards.
