SUPPLEMENTARY INFORMATION: Section 101(c) of the Federal Mine Safety
and Health Act of 1977 and Title 30 of the Code of Federal Regulations
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 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. 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 for filing petitions for modification.
II. Petitions for Modification
Docket Number: M-2020-022-C.
Petitioner: Century Mining LLC, 200 Chapel Brook Drive, Bridgeport,
West Virginia 26330.
Mine: Longview Mine, MSHA I.D. No. 46-09447, located in Barbour
County, West Virginia.
[[Page 66583]]
Regulation Affected: 30 CFR 75.507-1 (Electric equipment other than
power-connection points; outby the last open crosscut; return air;
permissibility requirements.).
Modification Request: The petitioner requests a modification of the
existing standard to permit an alternative method of compliance to
allow the use of battery-powered nonpermissible surveying equipment
including total station surveying equipment, distance meters,
theodolites, and data loggers, in return air, outby the last open
crosscut.
The petitioner states that:
(a) To support mining operations, specifically for accurately
locating entries, bore holes, gas wells, and other features, mine
surveying will be used. Accurate surveying is important for mine
required ventilation maps in 30 CFR 75.372 and 75.1200. Surveying
technology has advanced greatly in recent years, allowing for increased
accuracy, which promotes miner safety. These new surveying systems are
battery powered and are not MSHA-certified. For this equipment to be
employed in the Longview mine, the petitioner has submitted this
petition for modification of 30 CFR 75.507-1(a).
As an alternative to the existing standard, the petitioner proposes
the following:
(a) The petitioner proposes to use battery operated transits, total
station surveying equipment, distance meters and data loggers in return
air, outby the last open crosscut. The petition proposes the use of
theodolites and similar low-voltage battery-operated total stations and
theodolites if they have an ingress protection (IP) rating of 66 or
greater in the subject area, according to this petition.
(1) If the surveying equipment operates using lithium batteries, it
must meet the battery safety standard: UL1642 or IEC 62133.
(2) If an IP 66 rating is not possible, the highest IP rating will
be used.
(b) A record of the equipment will be kept on mine property in
either a secure book or electronically in a secure computer where the
records will not be alterable. The record will contain: The date of
manufacture and/or the purchase information of each piece of survey
equipment, proof of compliance with lithium battery standards, and the
original equipment manufacturers' user and maintenance manuals. These
records will be made available to MSHA and miners at the mine.
(c) Survey equipment will be examined by a qualified person, as in
30 CFR 75.153, before the equipment is taken underground to ensure safe
operating conditions. The minimum requirements of the examination by a
qualified person are the following:
(1) Check the equipment for physical damage and the integrity of
the case;
(2) Remove the battery and check for corrosion, if removable;
(3) Inspect the contact points to ensure a secure connection to the
battery, if removable;
(4) Reinsert the battery, power up and shut down to ensure proper
connections, if accessible;
(5) Check the battery compartment cover or battery attachment to
ensure that it is securely fastened; and
(6) For equipment utilizing lithium cells, the cells will be
inspected to ensure they are not damaged or swelled in size.
(d) A qualified person, as in 30 CFR 75.512-2, will examine the
equipment weekly and record the results. Records will be maintained for
at least one year.
(e) The equipment will be serviced per the manufacturers'
recommendation, dates of service and a description of any work
performed will be recorded.
(f) Surveying equipment will not be used if methane is detected in
concentrations at or above 1.0 percent. When 1.0 percent or more
methane is detected while such equipment is being used, the equipment
will be de-energized immediately and withdrawn outby the last open
crosscut. Batteries will not be removed to de-energize equipment due to
the possibility of accidental short-circuiting. All requirements of 30
CFR 75.323 will be complied with prior to entering the subject area.
(g) A qualified person, as in 30 CFR 75.100, will conduct a visual
examination of the location that the survey equipment will be used in
before the equipment is taken into or energized in that area. The
visual examination will include: Evidence that the area is properly
rock dusted and whether there is an accumulation of combustible
material (such as float coal dust). If float coal dust is observed in
suspension then the equipment cannot be energized until sufficient rock
dusting has been applied and/or the combustible material has been
cleaned up or removed.
(h) A methane test will be made at least 12 inches from the roof,
face, ribs, and floor (under 30 CFR 75.323) before energizing equipment
in the subject area.
(i) Hand-held methane detectors will be MSHA-approved as set forth
by 30 CFR 75.320. Measurement devices will be calibrated or bump tested
before each shift to ensure that they function properly. Methane
detectors will provide visual and audible warnings when methane is
detected above 1.0 percent.
(j) As required by 30 CFR 75.360, the subject area must be pre-
shift examined before using surveying equipment. If not examined during
the pre-shift, a supplemental examination will be conducted (under 30
CFR 75.361) before a noncertified person enters the subject area.
(k) Prior to survey equipment entering the subject area, a
qualified person must confirm, either by measurement or inquiry of the
certified person in charge of the section, that the air quantity meets
the minimum quantity required by the mine's approved ventilation plan.
(l) Methane will be continuously monitored before and during the
use of equipment in the subject area by a qualified person.
(m) Batteries must be ``exchanged'' in the intake area and no work
will be performed on the equipment while in the subject area.
(n) Personnel using the equipment will be qualified, as in 30 CFR
75.153, and trained according to the manufacturer's recommended safe
use procedures, including recognizing hazards associated with using
equipment where methane could be present.
(o) The above non-permissible survey equipment will be used when
production is occurring, if the following conditions are met:
(1) Nonpermissible electronic surveying equipment will not be used
in a split of air ventilating an MMU if any ventilation controls will
be disrupted during such surveying. Disruption of ventilation controls
means any change to the mine's ventilation system that causes the
ventilation system not to function in accordance with the mine's
approved ventilation plan.
(2) If a surveyor must disrupt ventilation while surveying, the
surveyor will stop surveying and communicate to the section foreman
that ventilation is disrupted. Production will stop while ventilation
is disrupted. Ventilation controls will be reestablished immediately
after the disruption is no longer necessary. Production will only
resume after all ventilation controls are reestablished and are in
compliance with approved ventilation or other plans, and other
applicable laws, standards, or regulations.
(3) All surveyors, section foremen, section crew members, and other
personnel who will be involved with or affected by surveying operations
will receive training in accordance with 30 CFR 48.7 on the
requirements of the petition. The training will be completed
[[Page 66584]]
before any nonpermissible electronic surveying equipment can be used
while production is occurring. The petitioner will keep a record of the
training and provide the record to MSHA on request.
(4) The petitioner will provide annual retraining to all personnel
who will be involved with or affected by surveying operations in
accordance with 30 CFR 48.8. The petitioner will train new miners on
the requirements of the petition in accordance with 30 CFR 48.5, and
will train experienced miners, as defined in 30 CFR 48.6, on the
requirements of the petition in accordance with 30 CFR 48.6. The
petitioner will keep a record of the training and provide the record to
MSHA personnel on request.
(p) The petitioner asserts that the proposed alternative method
will at all times guarantee no less than the same measure of protection
afforded by the existing standard.
Docket Number: M-2020-023-C.
Petitioner: Century Mining LLC, 200 Chapel Brook Drive, Bridgeport,
West Virginia 26330.
Mine: Longview Mine, MSHA I.D. No. 46-09447, located in Barbour
County, West Virginia.
Regulation Affected: 30 CFR 75.507-1 (Electric equipment other than
power-connection points; outby the last open crosscut; return air;
permissibility requirements.).
Modification Request: The petitioner requests a modification of the
existing standard to permit the use of nonpermissible electronic
testing and diagnostic equipment, in return air, outby the last open
crosscut.
The petitioner states that:
(a) To support mining, electrical testing and diagnostic equipment
is necessary. Modern mining equipment includes programmable logic
controllers, which use digital signals from machine sensors to make
decisions based on logic, to govern machine systems. To troubleshoot
such modern systems, as required by 30 CFR 75.503, certain electronic
tools are needed such as electronic tachometers. This electronic
equipment includes: Laptop computers to communicate with machine
control systems; vibration, temperature, and electronic tachometers to
support preventative and predictive maintenance to identify hazards;
cable fault detectors and insulation testers (meggers), which identify
and locate insulation failures in trailing cables, electric motors, and
control cables with power removed; oscilloscopes to view machine
control and communication signals for proper wave forms frequency and
amplitude, removing improper control signals that can create hazards to
mine personnel; voltage, current, resistance, and power test meters for
troubleshooting that mining machines and systems are properly
functioning. These electronic systems are not currently MSHA-certified
and do not meet the requirements of 30 CFR 75.507-1(a). For this
equipment to be employed in the Longview mine, the mine operator has
submitted this petition for modification.
As an alternative to the existing standard, the petitioner proposes
the following:
(a) The petitioner proposes using the following testing and
diagnostic equipment in return air, outby the last open crosscut:
Laptop computers, oscilloscopes, vibration analysis machines, cable
fault detectors, point temperature probes, infrared temperature
devices, insulation testers (meggers), voltage, current, resistance
meters, power testers, and electronic tachometers. Other testing and
diagnostic equipment would also be used if approved in advance by
MSHA's District Manager. The petitioner will use more than one piece of
testing equipment at the same time.
(b) Methane will be continuously monitored by a qualified person,
as defined in 30 CFR 75.151, before and during the use of
nonpermissible electronic testing and diagnostic equipment in return
air, outby the last open crosscut.
(c) Surveying equipment will not be used if methane is detected in
concentrations at or above 1.0 percent. When 1.0 percent or more
methane is detected while such equipment is being used, the equipment
will be de-energized immediately and withdrawn outby the last open
crosscut.
(d) Hand-held methane detectors will be MSHA-approved as set forth
by 30 CFR 75.320. They will be maintained in permissible and proper
operating condition.
(e) Coal production will be halted, except for when it is necessary
to troubleshoot under working mining conditions; coal can remain in or
on the equipment to troubleshoot equipment underload. Production will
be halted unless testing. Coal accumulation and other combustible
materials, as in 30 CFR 75.400, will be removed prior to testing, as a
safety precaution.
(f) Nonpermissible testing and diagnostic equipment will not be
used for testing when float coal dust is in suspension.
(g) Testing and Diagnostic equipment will be used as recommended by
the manufacturer, to ensure safe use procedures.
(h) Miners who will use the above equipment will be trained to
understand hazards and limitations associated with the equipment.
(i) Equipment in this petition will be inspected by MSHA before it
is put into service underground.
(j) Cables used for powering low-voltage testing and diagnostic
