SUPPLEMENTARY INFORMATION: Section 101(c) of the Federal Mine Safety
and Health Act of 1977 and title 30 of the Code of Federal Regulations
(CFR), 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, Sec. Sec. 44.10 and 44.11 of 30 CFR establish the
requirements for filing petitions for modification.
II. Petition for Modification
Docket Number: M-2024-040-C.
Petitioner: Tunnel Ridge, LLC, 184 Schoolhouse Lane, Valley Grove,
WV 26060.
Mine: Tunnel Ridge Mine, MSHA ID No. 46-08864, located in Ohio
County, West Virginia.
Regulation Affected: 30 CFR 75.1002(a), Permissible electric
equipment.
Modification Request: The petitioner requests a modification of 30
CFR 75.1002(a) to allow the use of unapproved Powered Air Purifying
Respirators (PAPRs) within 150 feet of pillar workings or longwall
faces. Specifically, the petitioner is requesting to utilize the
CleanSpace EX PAPR and sealed motor/blower/battery power pack assembly,
and the 3M Versaflo TR-800 Intrinsically Safe PAPR motor/blower and
battery with battery pack.
The petitioner states that:
(a) The 3M Versaflo TR-800 PAPR with motor/blower and battery
qualifies as intrinsically safe.
(b) The CleanSpace EX PAPR also qualifies as intrinsically safe.
(c) Both the CleanSpace EX and the 3M Versaflo TR-800 PAPRs provide
a constant flow of air inside the mask or helmet. This airflow provides
respiratory protection and comfort in hot working conditions.
(d) Neither the 3M Versaflo TR-800 nor the CleanSpace EX PAPR is
MSHA-approved as permissible.
(e) Neither the 3M nor the CleanSpace is pursuing MSHA approval.
(f) Tunnel Ridge currently makes available to all miners NIOSH-
approved high efficiency 100 series respirators to protect the miners
against potential exposure to respirable coal mine dust, including
crystalline silica, during normal mining conditions. Tunnel Ridge
desires to expand the miners' option in choosing a respirator that
provides the greatest degree of protection as well as comfort while
being worn. Powered PAPRs provide a constant flow of filtered air and
serve that purpose.
(g) On April 18, 2024 (89 FR 28218), MSHA issued a final rule
entitled Lowering Miners' Exposure to Respirable Crystalline Silica and
Improving Respiratory Protection. The rule requires the mine operator
to have a written respiratory protection program in place when miners
are required to use respirators. Adding the CleanSpace EX and the 3M
TR-800 Versaflo PAPRs to the respiratory protection program as
additional options will provide the miners with alternatives to the
series 100 high efficiency respirators already in use at the mine. The
PAPRs will also serve as a respirator option to protect the miners with
facial hair who may not be able to pass the ``fit test'' requirement of
the program. In addition, the positive flow of filtered air provided by
the PAPRs will provide a solution for the miners who are unable to wear
a tight-fitting respirator.
(h) Since the 3M Airstream Headgear-Mounted PAPR System has been
discontinued by the manufacturer, there are no other MSHA-approved
units available that can be used within 150 feet of pillar workings or
longwall faces.
(i) The alternative method in the petition will at all times
guarantee no less than the same measure of protection afforded to the
miners by the standard.
The petitioner proposes the following alternative method:
(a) All miners who will be involved with or affected by the use of
the 3M Versaflo TR-800 or CleanSpace EX PAPRs shall receive training in
accordance with 30 CFR 48.7 on the requirements of the Proposed
Decision and Order (PDO) granted by MSHA and manufacturer guidelines.
Such training shall be completed before any 3M Versaflo TR-800 or
CleanSpace EX PAPR can be used within 150 feet of pillar workings or
longwall faces. The operator shall keep a record of such training and
provide such record to MSHA upon request.
(b) The PAPRs, battery packs, all associated wiring and connections
shall be inspected before use to determine if there is any damage to
the units that would negatively impact intrinsic safety. If any defects
are found, the PAPR shall be removed from service.
(c) A separate logbook shall be maintained for the 3M Versaflo TR-
800 and CleanSpace EX PAPRs that will be kept with the equipment, or in
a location with other mine record books, and shall be made available to
MSHA upon request. The equipment shall be examined at least weekly by a
qualified person as defined in 30 CFR 75.512-1 and the examination
results shall be recorded in the logbook. Examination records shall be
maintained for one year.
(d) All 3M Versaflo TR-800 and CleanSpace EX PAPRs to be used
within 150 feet of pillar workings or longwall faces shall be
physically examined prior to initial use and each unit shall be
assigned a unique identification number. Each unit shall be examined by
the person to operate the equipment prior to taking the equipment
underground to ensure that the equipment is used according to the
original equipment manufacturer's recommendations and is maintained in
a safe operating condition. The examinations for the 3M Versaflo TR-800
PAPRs shall include:
(1) Check the equipment for any physical damage and the integrity
of the case.
(2) Remove the battery and inspect for corrosion.
(3) Inspect the contact points to ensure a secure connection to the
battery.
(4) Reinsert the battery and power up and shut down to ensure
proper connections.
(5) Check the battery compartment cover or battery attachment to
ensure that it is securely fastened.
(6) For equipment utilizing lithium type cells, ensure that lithium
cells and/
[[Page 90060]]
or packs are not damaged or swelled in size.
The CleanSpace EX PAPR does not have an accessible/removable
battery. The internal battery and motor/blower assembly are both
contained within the ``power unit'' assembly and the battery cannot be
removed, reinserted or fastened. Therefore, examination of the
CleanSpace EX PAPR shall include any indications of physical damage.
(e) All 3M Versaflo TR-800 and CleanSpace EX PAPR units shall be
serviced according to the manufacturer's recommendations.
(f) Prior to energizing and during use of the 3M Versaflo TR-800 or
the CleanSpace EX PAPR within 150 feet of pillar workings or longwall
faces, procedures in accordance with 30 CFR 75.323 shall be followed.
(g) Only the 3M TR-830 Battery Pack, which meets lithium battery
safety standard UL 1642 or IEC 62133, in the 3M Versaflo TR-800 PAPR
shall be used. Only the CleanSpace EX Power Unit, which meets lithium
battery safety standard UL 1642 or IEC 62133, in the CleanSpace EX
shall be used.
(h) If battery packs for the 3M Versaflo TR-800 PAPR are provided,
all battery ``change outs'' shall occur in intake air outby the last
open crosscut.
(i) The following maintenance and use conditions shall apply to
equipment containing lithium type batteries:
(1) Neither the 3M TR-830 Battery Pack nor the CleanSpace EX Power
Unit shall be disassembled nor modified by anyone other than permitted
by the manufacturer of the equipment.
(2) The 3M TR-830 Battery Pack shall be charged only in an area
free of combustible material and in intake air outby the last open
crosscut. The 3M TR-830 Battery Pack shall be charged only by a
manufacturer's recommended battery charger, such as:
(i) 3M Battery Charger Kit TR-641N, which includes one 3M Charger
Cradle TR-640 and one 3M Power Supply TR-941N, or,
(ii) 3M 4-Station Battery Charger Kit TR-644N, which includes four
3M Charger Cradles TR-640 and one 3M 4-Station Battery Charger Base/
Power Supply TR-944N.
(3) The CleanSpace EX internal battery, which is contained within
the power unit assembly, shall be charged in areas located outby the
last open crosscut in intake air and only the manufacturer's
recommended battery chargers shall be used, such as the CleanSpace EX
Battery Charger, Product Code PAF-0066.
(4) Neither the 3M TR-830 Battery Pack nor the CleanSpace EX power
unit which contains the internal battery, shall be exposed to water,
allowed to get wet or immersed in liquid. This does not preclude
incidental exposure of the 3M TR-830 Battery Pack or the CleanSpace EX
power unit assembly.
(5) Neither the 3M Versaflo TR-800 PAPR nor the CleanSpace EX PAPR,
including the internal battery, shall be used, charged or stored in
locations where the manufacturer's recommended temperature limits are
exceeded. Neither the 3M Versaflo TR-800 PAPR nor the CleanSpace EX
PAPR shall be placed in direct sunlight nor stored near a source of
heat.
(j) Annual retraining shall be given to all miners who will be
involved with or affected by the use of the 3M Versaflo TR-800 or
CleanSpace EX PAPRs in accordance with 30 CFR 48.8. Training of new
miners on the requirements of the PDO granted by MSHA in accordance
with 30 CFR 48.5, and training of experienced miners on the
requirements of the PDO granted by MSHA in accordance with 30 CFR 48.6
shall be given. The operator shall keep a record of such training and
provide such record to MSHA upon request.
(k) The miners at Tunnel Ridge, LLC, Tunnel Ridge Mine, are not
represented by a labor organization and there are no representatives of
miners at the mine. A copy of this petition has been posted on the
bulletin board at Tunnel Ridge, LLC, Tunnel Ridge Mine, on October 4,
2024.
The petitioner asserts that the alternative method in the petition
will at all times guarantee no less than the same measure of protection
afforded to the miners by the standard.
