DEPARTMENT OF LABOR
Mine Safety and Health Administration
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: 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.

Petitioner: Kennecott Utah Copper
Reg Affected: 30 CFR 56.9300 (previously 56.9022)
Summary of Findings: On December 3, 1986, Petitioner filed a petition
seeking a modification of the application of 30 CFR 56.9022 to its Utah
Copper Division Concentrator Plants located in Magna, Salt Lake County,
Utah. The petitioner alleging that application of the standard would
result in a diminution of safety to the miners and that the alternative
method outlined in the petition would guarantee no less than the same
measure of protection as the mandatory standard. A Proposed Decision
and Order (PDO) was issued granting this petition on May 25, 1988. On
June 24, 1988, petitioner submitted comments requesting correction to
certain sections in the PDO. On July 14, 1988, MSHA issued an amended
PDO incorporating the changes requested by petitioner, allowing the
operator to use the tailings impoundment roadway without berms or
guards conditioned upon petitioner's compliance with specific factors
and upon circumstances existing at the mine at the time modification
was granted. On October 24, 1988, the mandatory standard was revised
and redesignated as 56.9300. On July 26, 1994, petitioner submitted a
request for petition to be amended, noting that conditions have changed
since previous petition was granted. After review of the entire record,
and MSHA's investigative report and recommendations, an amended PDO was
issued on March 8, 1995, modifying the granted modification of 30 CFR
56.9022 to Kennecott Utah Copper Concentrator--North. On March 28,
1995, petitioner submitted [[Page 32184]] comments requesting
