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, sections 44.10 and 44.11 of 30 CFR establish the 
requirements for filing petitions for modification.

II. Petition for Modification

    Docket Number: M-2025-020-C.
    Petitioner: ICG Beckley, LLC, P.O. Box 49, Eccles, West Virginia 
25836.
    Mine: Beckley Pocahontas Mine, MSHA ID No. 46-05252, located in 
Raleigh County, West Virginia.
    Regulation Affected: 30 CFR 75.507-1(a), Electric equipment other 
than power-connection points; outby the last open crosscut; return air; 
permissibility requirements.
    Modification Request: The petitioner requests a modification of 30 
CFR 75.507-1(a) to allow the use of unapproved Powered Air Purifying 
Respirators (PAPRs) in return air outby the last open crosscut. 
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) Previously, they have used the 3MTM Airstream TM helmet to 
provide additional protection for miners against exposure to respirable 
coal mine dust. There are clear long-term health benefits from using 
such technology.
    (b) 3M elected to discontinue the 3MTM Airstream TM helmet, 
replacing it with a 3M Versaflo TM TR-800 which benefits from 
additional features and reduced weight. Because of its reduced weight, 
it provides significant ergonomic benefits.
    (c) For more than 40 years the 3MTM Airstream TM Headgear-Mounted 
PAPR System has been used by many mine operators to help protect their 
workers. During those years there have been technological advancements 
in products and services for industrial applications. 3M indicated that 
they had faced multiple key component supply disruptions for the 
Airstream TM product line that created issues with providing acceptable 
supply service levels. Because of those issues, 3M discontinued the 
Airstream TM in June 2020, and this discontinuation is global.
    (d) 3M announced that February 2020 was the final time to place an 
order for systems and components and that June 2020 was the final date 
to purchase Airstream TM components.
    (e) Currently there are no replacement 3M PAPRs that meet 
applicable MSHA standards for permissibility. Electronic equipment used 
in underground mines in potentially explosive atmospheres is required 
to be approved by MSHA in accordance with 30 CFR. 3M and other 
manufacturers offer alternative products for many other environments 
and applications.
    (f) Following the discontinuation, mines that currently use the 
Airstream TM do not have an MSHA-approved

[[Page 13209]]

alternative PAPR to provide to miners. One of the benefits of PAPRs is 
that they provide a constant flow of air inside the headtop or helmet. 
This constant airflow helps to provide both respiratory protection and 
comfort in hot working environments.
    (g) Application of the standard results in a diminution of safety 
at the mine.
    (h) The 3M Versaflo TR-800 motor/blower and battery qualify as 
intrinsically safe in the U.S., Canada, and any other country accepting 
IECEx (International Electrotechnical Commission System for 
Certification to Standards Relating to Equipment for Use in Explosive 
Atmospheres) reports. The 3M Versaflo TR-800 has a blower that is UL-
certified with an intrinsically safe (IS) rating of Division 1: IS 
Class I, II, III; Division 1 (includes Division 2) Groups C, D, E, F, 
G; T4, under the most current standard (UL 60079, 6th Edition, 2013). 
It is ATEX-certified with an IS rating of ``ia.'' (ATEX refers to 
European directives for controlling explosive atmospheres.) It is rated 
and marked with Ex ia I Ma, Ex ia IIB T4 Ga, Ex ia IIIC 135 [deg]C Da, 
-20 [deg]C <= Ta <= +55 [deg]C, under the current standard (IEC 60079).
    (i) ICG Beckley Mine seeks modification to also permit the use of 
the CleanSpace EX powered respirator under the same conditions as it 
proposed with respect to the 3M Versaflo TR-800. It too has been 
determined to be intrinsically safe.
    (j) The 3M Versaflo TR-800 is not MSHA approved as permissible, and 
3M is not pursuing approval.
    (k) The CleanSpace EX Power Unit is not MSHA approved as 
permissible, and CleanSpace is not pursuing approval.
    (l) The standards for approval of these respirators are an 
acceptable alternative to MSHA's standards and provide an equivalent 
level of protection.
    The petitioner proposes the following alternative method:
    (a) Affected mine employees shall be trained in the proper use and 
maintenance of the 3M Versaflo TR-800 and the CleanSpace EX in 
accordance with established manufacturer guidelines. This training 
shall alert the affected employee that neither the 3M Versaflo TR-800 
nor the CleanSpace EX is approved under 30 CFR part 18 and must be de-
energized when 1.0 or more percent methane is detected. The training 
shall also include the proper method to de-energize these PAPRs. In 
addition to manufacturer guidelines, the petitioner shall require that 
mine employees be trained to inspect the units before use to determine 
if there is any damage to the units that would negatively impact 
intrinsic safety as well as all stipulations in this petition.
    (b) The PAPRs, battery packs, and 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) ICG Beckley, LLC shall maintain a separate logbook for the 3M 
Versaflo TR-800 and CleanSpace EX PAPRs that shall 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 recorded in the logbook. Since float coal dust 
is removed by the air filter prior to reaching the motor, the PAPR user 
shall conduct regular examinations of the filter and perform periodic 
testing for proper operation of the ``high filter load alarm'' on the 
3M Versaflo TR-800 and the ``blocked filter'' alarm on the CleanSpace 
EX. Examination entries may be expunged after one year.
    (d) All 3M Versaflo TR-800 and CleanSpace EX PAPRs that shall be 
used in return air outby the last open crosscut, 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 the equipment is being used according to the original equipment 
manufacturer's recommendations and maintained in a safe operating 
condition.
    (e) The examination for the 3M Versaflo TR-800 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; and
    (6) For equipment utilizing lithium type cells, ensure that lithium 
cells and/or packs are not damaged or swelled in size.
    (f) The CleanSpace EX does not have an accessible/removable 
battery. The battery and motor/blower assembly are both contained 
within the sealed power pack assembly and cannot be removed, 
reinserted, or fastened. The pre-use examination is limited to 
inspecting the equipment for indications of physical damage.
    (g) ICG Beckley, LLC shall ensure that all 3M Versaflo TR-800 and 
CleanSpace EX PAPRs are serviced according to the manufacturer's 
recommendations. Dates of service shall be recorded in the equipment's 
log book and shall include a description of the work performed.
    (h) The 3M Versaflo TR-800 and CleanSpace EX PAPRs that shall be 
used in return air outby the last open crosscut or in areas where 
methane may enter the air current, shall not be put into service until 
MSHA has initially inspected the equipment and determined that it is in 
compliance with all the terms and conditions of the Proposed Decision 
and Order (PDO) granted by MSHA.
    (i) Prior to energizing the 3M Versaflo TR-800 or the CleanSpace EX 
in return air outby the last open crosscut, methane tests shall be made 
in accordance with 30 CFR 75.323(a).
    (j) All hand-held methane detectors shall be MSHA-approved and 
maintained in permissible and proper operating conditions as defined by 
30 CFR 75.320. All methane detectors shall provide visual and audible 
warnings when methane is detected at or above 1.0 percent.
    (k) A qualified person as defined in 30 CFR 75.151 shall 
continuously monitor for methane immediately before and during the use 
of the 3M Versaflo TR-800 or CleanSpace EX in return air outby the last 
open crosscut, or in areas where methane may enter the air current.
    (l) Neither the 3M Versaflo TR-800 nor the CleanSpace EX shall be 
used if methane is detected in concentrations at or above 1.0 percent. 
When 1.0 percent or more of methane is detected while the 3M Versaflo 
TR-800 or CleanSpace EX is being used, the equipment shall be de-
energized immediately and the equipment withdrawn outby the last open 
crosscut.
    (m) ICG Beckley, LLC shall use only the 3M TR-830 Battery Pack, 
which meets lithium battery safety standard UL 1642 or IEC 62133 in the 
3M Versaflo TR-800. The petitioner shall use only the CleanSpace EX 
Power Unit which meets lithium battery safety standard UL 1642 or IEC 
62133 in the CleanSpace EX.
    (n) The battery packs shall be ``changed out'' in intake air outby 
the last open crosscut. Before each shift when the 3M Versaflo TR-800 
or CleanSpace EX is to be used, all batteries and power units for the 
equipment shall be charged sufficiently so that they are not expected 
to be replaced on that shift.

[[Page 13210]]

    (o) The following maintenance and use conditions shall apply to 
equipment containing lithium-type batteries:
    (1) Always correctly use and maintain the lithium-ion battery 
packs. Neither the 3M TR-830 Battery Pack nor the CleanSpace EX Power 
Unit shall be disassembled or modified by anyone other than persons

    (p) Personnel engaged in the use of the 3M Versaflo TR-800 and 
CleanSpace EX PAPRs shall be properly trained to recognize the hazards 
and limitations associated with the use of the equipment in areas where 
methane could be present. Additionally, personnel shall be trained 
regarding proper procedures for donning Self Contained Self Rescuers 
(SCSRs) during a mine emergency while wearing the 3M Versaflo TR-800 or 
CleanSpace EX. The mine operator shall submit proposed revisions to 
update the Mine Emergency Evacuation and Firefighting Program of 
Instruction under 30 CFR 75.1502 to address this issue.
    (q) Within 60 days after the PDO granted by MSHA becomes final, ICG 
Beckley Pocahontas Mine shall submit proposed revisions for its 
approved 30 CFR part 48 training plans to the Mine Safety and Health 
Enforcement District Manager. These proposed revisions shall specify 
initial and refresher training regarding the terms and conditions 
stated in the PDO granted by MSHA. When training is conducted on the 
terms and conditions in the PDO granted by MSHA, an MSHA Certificate of 
Training (Form 5000-23) shall be completed. Comments shall be included 
on the Certificate of Training indicating that the training received 
was for use of the 3M Versaflo TR-800 or CleanSpace EX.
    (r) All personnel who shall be involved with or affected by the use 
of the 3M Versaflo TR-800 or CleanSpace EX shall receive training in 
accordance with 30 CFR 48.7 on the requirements of the PDO granted by 
MSHA within 60 days of the date the PDO becomes final. Such training 
shall be completed before any 3M Versaflo TR-800 or CleanSpace EX can 
be used in return air outby the last open crosscut. The operator shall 
keep a record of such training and provide such record to MSHA upon 
request.
    (s) ICG Beckley, LLC shall provide annual retraining to all
