Part 44 govern the application, processing, and disposition of 
petitions for modification.

I. Background

    Section 101(c) of the Federal Mine Safety and Health Act of 1977 
(Mine Act) allows the mine operator or representative of miners to file 
a petition to modify the application of any mandatory safety standard 
to a coal or other mine if the Secretary of Labor (Secretary) 
determines that:
    1. An alternative method of achieving the result of such standard 
exists which will at all times guarantee no less than the same measure 
of protection afforded the miners of such mine by such standard; or
    2. That the application of such standard to such mine will result 
in a diminution of safety to the miners in such mine.
    In addition, the regulations at 30 CFR 44.10 and 44.11 establish 
the requirements and procedures for filing petitions for modification.

from the mine roof or a substantial bridge for equipment to pass over 
the cables will be used.
    (28) Excessive cable will be stored behind the anchor(s) on 
equipment that use cable reels to prevent cable overheating.
    (29) The petitioner's alternative method will not be implemented 
until all miners who have been designated to examine the integrity of 
seals, verify the short-circuit settings, and examine trailing cables 
for defects have received training.
    (30) The equipment listed in this petition will comply with all 
other applicable requirements of the Federal Mine Safety and Health Act 
of 1977 and the applicable requirements of 30 CFR part 75.
    (31) Within 60 days after the proposed decision and order becomes 
final, the petitioner will submit proposed revisions for its approved 
30 CFR part 48 training plan to the District Manager for the area in 
which the mine is located. These proposed revisions will specify task 
training for miners designated to examine the trailing cables for safe 
operating condition and verify that the short-circuit settings of the 
circuit interrupting devices that protect the affected trailing cables 
do not exceed the settings specified in this petition. The training 
will include the following:
    (a) The hazards of setting the circuit interrupting devices too 
high to adequately protect the trailing cables.
    (b) How to verify that the circuit interrupting devices protecting 
the trailing cables are properly set and maintained.
    (c) Mining and operating procedures that will protect the trailing 
cables against damage.
    (d) How to protect the trailing cables against damage caused by 
overheating cables due to excessive cable stored on cable reel(s) and 
adjusting stored cable behind the cable anchor(s) as tramming distances 
change.
    (e) Proper procedures for examining the trailing cables to ensure 
that cables are in safe operating condition by a visual inspection of 
the entire cable, observing the insulation, the integrity of splices, 
and nicks and abrasions.
    The petitioner asserts that a decision in favor of this petition 
will in no way provide less than the same measure of protection 
afforded the miners under the existing standard.
    Docket Number: M-2018-001-M.
    Petitioner: Martin Marietta Kansas City, LLC, 1099 18th Street, 
Suite 2150, Denver, Colorado 80202.
    Mine: Randolph Deep Mine, MSHA I.D. No. 23-02308, located in Clay 
County, Missouri; Stamper Underground Mine, MSHA I.D. No. 23-02232 and 
Parkville Quarry, MSHA I.D. No. 23-01883, located in Platte County, 
Missouri.
    Regulation Affected: 30 CFR 49.6(a)(1) (Equipment and maintenance 
requirements).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the maintenance of a minimum of six 
approved self-contained breathing apparatus at its mine rescue station 
in lieu of twelve self-contained breathing apparatus. The petitioner 
proposes to maintain a mine rescue station with a minimum of six 
approved self-contained breathing apparatus and all equipment 
identified in 30 CFR 49(a)(2) through (a)(9). This station would 
contain sufficient equipment to equip one mine rescue team.
    The petitioner states that:
    (1) The Randolph Deep Mine is an underground limestone mine with 
active workings accessed from the surface via twin declines, located 
adjacent to one another and each 6750 feet long. It is a room and 
pillar mine with multiple openings to active mining areas.
    (2) The Stamper Underground Mine is an underground limestone mine 
with active workings accessed from the surface via two separate adits 
or entries; a decline for foot and vehicular traffic that is 1800 feet 
long and a single escape shaft, which is 350 feet in depth and equipped 
with a hoist for emergency evacuation. It is a room and pillar mine 
with multiple openings to active mining areas.
    (3) The Parkville Quarry is an underground limestone mine with 
active workings accessed from the surface via three separate adits or 
entries; a 900 feet long decline for foot and vehicular traffic and two 
shafts equipped with ladders for emergency evacuation. Shaft No. 1 is 
145 feet deep and Shaft No. 2 is 190 feet deep. It is a room and pillar 
mine with multiple openings to active mining areas.
    (4) The petitioner has established a single mine rescue team to 
serve as the primary mine rescue team for all three of the mine sites. 
The mine rescue team consists of seven qualified and trained members.
    (5) The petitioner has entered into an agreement with Central 
Plains Cement Company (``Central Plains'') whereby Central Plains 
agrees to provide mine rescue services by the Sugar Creek Mine Rescue 
Team as needed to petitioner. Central Plains is controlled by Eagle 
Materials, Inc. Similarly, petitioner has agreed to provide mine rescue 
services as needed to Central Plains.
    (6) The petitioner has a mine rescue station located at the 
Randolph Deep Mine which previously contained equipment sufficient only 
to supply one mine rescue team. Both the Stamper Underground Mine and 
the Parkville Quarry are within thirty minutes or less of ground travel 
time from the Randolph Deep mine. Sugar Creek had its own mine rescue 
station located within fifteen minutes of ground travel time from the 
Randolph mine. The Sugar Creek mine rescue station initially contained 
equipment sufficient to equip one mine rescue team. As of December 20, 
2017, petitioner has relocated certain mine rescue team equipment,

[[Page 4930]]

including six self-contained breathing apparatus, gas monitors, cap 
lamps, and oxygen bottles to the Sugar Creek Mine rescue station to 
ensure that the combined mine rescue station is in compliance with 30 
CFR 49.6(a).
    (7) Pursuant to the mine rescue services arrangement between 
petitioner and Central Plains, there will always be two mine rescue 
teams available whenever miners are underground and a minimum of twelve 
approved self-contained breathing apparatus available for a mine 
emergency. When maintained in the individual mine rescue stations, the 
apparatus could be used immediately or transported to another mine 
within a maximum forty-five minutes ground travel time.
    (8) The Petitioner proposes the following for its mine rescue 
station:
    (a) Self-Contained Breathing Apparatus: The mine rescue station 
will be equipped with a minimum of six self-contained breathing 
apparatus, each with a minimum of four hours capacity (approved by MSHA 
and the National Institute for Occupational Safety and Health under 42 
CFR part 84, subpart H), and any necessary equipment for testing such 
apparatus.
    (b) The mine operator will maintain a mine rescue station provided 
with all equipment identified in 30 CFR 49.6(a)(2) through (a)(9).
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded the miners under the existing standard.
