# ACTION:

Notice.

# SUMMARY:

The Federal Mine Safety and Health Act of 1977 and Title 30 of the Code of Federal Regulations govern the application, processing, and disposition of petitions for modification of mandatory safety standards. Any mine operator or representative of miners may petition for an alternative method of complying with an existing safety standard. MSHA reviews the content of each submitted petition, assesses the mine in question, and ultimately issues a decision on the petition. This notice includes a list of petitions for modification that were granted after MSHA's review and investigation, between April 20, 2019 and December 14, 2020.

# ADDRESSES:

                        Copies of the final decisions are posted on MSHA's website at                         *https://www.msha.gov/​regulations/​rulemaking/​petitions-modification*.

# SUPPLEMENTARY INFORMATION:

## I. Introduction

Under section 101 of the Federal Mine Safety and Health Act of 1977, any mine operator or representative of miners may petition to use an alternative approach to comply with a safety standard. In response, the Secretary of Labor (Secretary) or his or her designee may modify the application of a mandatory safety standard to that mine if the Secretary determines that: (1) An alternative method exists that will guarantee no less protection for the miners affected than that provided by the standard; or (2) the application of the standard will result in a diminution of safety to the affected miners.

                    MSHA bases the final decision on the petitioner's statements, any comments and information submitted by interested                           ( print page 320)                        persons, and a field investigation of the conditions at the mine. In some instances, MSHA may approve a petition for modification on the condition that the mine operator complies with other requirements noted in the decision. In other instances, MSHA may deny, dismiss, or revoke a petition for modification. In accordance with 30 CFR 44.5, MSHA publishes every final action granting a petition for modification.
