Permanent Program Performance Standards Related to Siltation Structures
Summary
The Office of Surface Mining (OSM) is establishing new permanent standards for how companies must manage siltation structures—barriers designed to trap sediment and prevent water pollution—at mining sites. This regulation ensures that these structures are properly built, maintained, and monitored to protect water quality and prevent environmental damage in communities near mining operations.
Key Points
- 1Mining companies must meet specific performance standards for building and maintaining structures that catch sediment and prevent dirt from polluting waterways
- 2These standards apply to all mining operations covered by federal surface mining rules and require regular inspection and maintenance of siltation barriers
- 3The regulation sets requirements for how these structures must be designed, how they should perform during heavy rainfall, and when they need repairs or replacement
- 4Companies must document and report on their siltation structure maintenance, giving regulators and the public visibility into compliance efforts
- 5The public has until December 30, 2025 to submit comments on the proposed rule before it becomes final
