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(c) of the Federal Mine Safety and Health Act
of 1977, the Secretary of Labor may modify 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.
Summaries of petitions received by the Secretary appear
periodically in the Federal Register. 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 has granted or partially granted
the requests for modification submitted by the petitioners listed
below. In some instances, the decisions are conditioned upon compliance
with stipulations stated in the decision.
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-

mined except when veins are interconnected to other veins beyond the
