Proposed Rule Stage



Priority: Other Significant

Legal Authority: 30 USC 957

CFR Citation: 30 CFR 36

Legal Deadline: None

Abstract: The Mine Safety and Health Administration is proposing to add field modification provisions to 30 CFR part 36 - Approval requirements for permissible mobile diesel-powered transportation equipment. Field modifications allow permissible equipment to be modified for mine- specific use or to comply with new diesel standards. The implementation of diesel regulations in 30 CFR parts 7, 36, 57, 72, and 75 has resulted ``in an increase in requests from owners of approved equipment, typically underground mine operators, to field modify permissible diesel-powered equipment. This proposed rule would codify the field modification process for part 36 field modification acceptances``, expand the field modification process to allow mine operators as defined in the Federal Mine Safety and Health Act 1977 to apply for field modifications, and continue to ensure that field- modified equipment operates safely in gassy underground mines. The proposed rule would implement existing policy which dates from 1985 to reflect current procedures for processing field modifications related to mobile diesel-powered transportation equipment. Also, the proposed rule would require that labeling provisions be applied to all new field modifications accepted under part 36. These new provisions would enhance miner safety.
