The Mine Act places the responsibility for ensuring the health and safety of miners on mine operators. Congress enacted the pattern of violations (POV) provision to provide MSHA with an additional enforcement tool when other tools had proven ineffective. Congress intended MSHA to use the POV provision to restore safe and healthful conditions at mines with a pattern of significant and substantial (S&S) violations. The legislative history states that Congress believed the existence of a pattern would signal to both the mine operator and the Secretary that there is a need to restore the mine to effective safe and healthful conditions and that the mere abatement of violations as they are cited is insufficient.

A mine operator that has a pattern of S&S violations at a mine will receive written notice from MSHA. For each subsequent S&S violation, MSHA will issue an order withdrawing miners from the affected area until the cited condition has been corrected. MSHA will terminate an operators POV notice when 1) an inspection of the entire mine is completed and no S&S violations are found or 2) no withdrawal order is issued by MSHA in accordance with Section 104(e)(1) of the Mine Act within 90 days of the issuance of the pattern notice.

Mine operators can determine whether they may be subject to a POV notice by using MSHAs Pattern of Violations Monitoring Tool. It is the responsibility of mine operators to track their violation and injury histories to determine whether they need to take action to avoid triggering a POV notice. Operators who are at risk of receiving a POV notice are encouraged to implement a corrective action program to reduce S&S violations. More information about corrective action programs can be found in MSHAs Pattern of Violations Procedures Summary.
