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 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, 1100 Wilson Boulevard,
Room 2352, Arlington, Virginia 22209. Contact Barbara Barron at 202-

Petitioner: Centralia Mining.
Regulation Affected: 30 CFR 75.1200 (d) and (i).
Summary of Findings: Petitioner's proposal is to use cross-sections
instead of contour lines through the intake slope, at locations of rock
tunnel connections between veins, and at 1,000 foot intervals of
advance from the intake slope; and to limit the required mapping of the
mine workings above and below to those present within 100 feet of the
vein being mined except when veins are interconnected to other veins
beyond the 100-foot limit through rock tunnels. The petitioner asserts
that due to the steep pitch encountered in mining anthracite coal
veins, contours provide no useful information and their presence would
make portions of the map illegible. The petitioner further asserts that
use of cross-sections in lieu of contour lines has been practiced since
the late 1800's thereby providing critical information relative to the
spacing between veins and proximity to other mine workings which
fluctuate considerably. This is considered an acceptable alternative

mining into inaccessible areas under 30 CFR 75.389 is required. This is
considered an acceptable alternative method for the Skidmore Slope
Mine. MSHA grants the petition for modification for annual revisions
and supplements of the mine map at the Skidmore Slope Mine with
conditions.
Docket No.: M-2001-117-C.

Slope Mine. MSHA grants the petition for modification for the use of
the hoist conveyance (gunboat) without safety catches at the Skidmore
Slope Mine with conditions.
