30 CFR § 104.1
Purpose and scope.
This part establishes the criteria and procedures for determining whether a
mine operator has established a pattern of significant and substantial (S&S)
violations at a mine. It implements section 104(e) of the Federal Mine Safety
and Health Act of 1977 (Act) by addressing mines with an inspection history
of recurrent S&S violations of mandatory safety or health standards that
demonstrate a mine operator's disregard for the health and safety of miners.
The purpose of the procedures in this part is the restoration of effective
safe and healthful conditions at such mines.
