Court Tosses Mining Water Filters, Sparking Eco-Debate
Published Date: 11/28/2025
Rule
Summary
Starting January 27, 2026, new rules will remove the requirement that all water runoff from mining sites must pass through siltation structures. This change affects mining companies regulated by the Office of Surface Mining and is a response to a court decision that said the old rule wasn’t backed up well enough. No extra costs are expected, but the public can comment until December 29, 2025, before the rule takes effect.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
Siltation-Structure Requirement Removed
Starting January 27, 2026, the rule removes the parts of 30 CFR 816.46 and 817.46 that required all surface drainage from a disturbed mining area to pass through a siltation structure before leaving the permit area. The change explicitly affects mining companies regulated by the Office of Surface Mining Reclamation and Enforcement (OSMRE). The public may submit significant adverse comments by December 29, 2025, before the rule takes effect.
Best-Technology Requirement Still Applies
The rule leaves paragraph (b)(1) in 30 CFR 816.46 and 817.46, which continues to require use of the "best technology currently available" to prevent additional suspended solids in runoff. That paragraph may still require siltation structures in specific cases where they are the best technology.
