Rescission of Portions of Permanent Program Performance Standards Related to Siltation Structures

The Office of Surface Mining Reclamation and Enforcement (OSM) is confirming the effective date of January 27, 2026, for the direct final rule "Rescission of Portions of Permanent Program Performance Standards Related to Siltation Structures," published on November 28, 2025. The direct final rule removes paragraphs that required that all surface drainage from the disturbed area pass through a siltation structure before leaving the permit area. These provisions were struck down by a reviewing court in 1985 and have no legal effect but were never removed from the Code of Federal Regulations. During the comment period, OSM received one substantive comment. That comment was not a significant adverse comment because it did not effectively challenge the rule's underlying premise or approach or explain why the rule would be inappropriate without a change. As a result, the comment does not warrant a delay of the effective date.
