Summary of Decisions Granting in Whole or in Part Petitions for Modification

AGENCY: Mine Safety and Health Administration (MSHA), Labor.

ACTION: Notice of affirmative decisions issued by the Administrators for Coal Mine Safety and Health and Metal and Nonmetal Mine Safety and Health on petitions for modification of the application of mandatory safety standards.

-----------------------------------------------------------------------

SUMMARY: Under section 101 of the Federal Mine Safety and Health Act of 1977, the Secretary of Labor (Secretary) may allow the modification of the application of a mandatory safety standard to a mine if the Secretary determines either that an alternate method exists at a specific mine that will guarantee no less protection for the miners affected than that provided by the standard, or that the application of the standard at a specific mine will result in a diminution of safety to the affected miners.
     Final decisions on these petitions are based upon the petitioner's statements, comments and information submitted by interested persons, and a field investigation of the conditions at the mine. MSHA, as designee of the Secretary, has granted or partially granted the requests for modification listed below. In some instances, the decisions are conditioned upon compliance with stipulations stated in the decision. The term ``FR Notice'' appears in the list of affirmative decisions below. The term refers to the Federal Register volume and page where MSHA published a notice of the filing of the petition for modification.

FOR FURTHER INFORMATION CONTACT: Petitions and copies of the final decisions are available for examination by the public in the Office of Standards, Regulations, and Variances, MSHA, Room 627, 4015 Wilson Boulevard, Arlington, Virginia 22203. Contact Barbara Barron at 703- 235-1910.

     Dated at Arlington, Virginia this 6th day of May 2002. Marvin W. Nichols, Jr., Director, Office of Standards, Regulations, and Variances.

Petitioner: FMC Corporation.
Regulation Affected: 30 CFR 57.22305.
Summary of Findings: Petitioner's proposal is to use a cordless drill or other equivalent drills to install surveying spads in the mine roof to minimize the potential of developing cumulative trauma disorders in the wrists, elbows, and shoulder of the surveyors. The petitioner propose to test for methane before using the drills and if one percent or more of methane is found, drilling will not begin and will be immediately stopped if a level of or greater than one percent methane is found. This is considered an acceptable alternative method for the Westvaco Mine. MSHA grants the petition for modification for the use Westvaco Mine with conditions.

FR Notice: 66 FR 9724.
Petitioner: ASARCO Incorporated.
Regulation Affected: 30 CFR 57.11055.
Summary of Findings: Petitioner's proposal is to use a vertical ladderway as an emergency escapeway, and as a secondary means of escape within the primary escapeway in the event of an extended power failure or repair to a damage hoist, to avoid hazards that are created by repeated unnecessary mine evacuations. This is considered an acceptable alternative method for the Coy Mine. MSHA grants the petition for modification for the Coy Mine during unplanned hoist outages to allow the Coy shaft ladderway to be designated as an escapeway 337 feet only when the Coy shaft hoist is incapacitated for unplanned reasons with conditions.
