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–2024–017–C. 

Petitioner: Warrior Coal, LLC, 57 J. E. 

Ellis Road, Madisonville, KY 42431. 

Mine: Cardinal Mine, MSHA ID No. 

15–17216, located in Hopkins County, 

Kentucky. 

Regulation Affected: 30 CFR 75.507– 

1(a), Permissible electric equipment. 

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) taken into or used 

inby the last open crosscut or used in 

the 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) 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.

80956 Federal Register / Vol. 89, No. 193 / Friday, October 4, 2024 / Notices 

(d) Neither the 3M Versaflo TR–800 

nor the CleanSpace EX PAPR is MSHAapproved as permissible. 

(e) Neither the 3M nor the CleanSpace 

is pursuing MSHA approval. 

(f) Warrior currently makes available 

to all miners NIOSH-approved high 

efficiency l00 series respirators to 

protect the miners against potential 

exposure to respirable coal mine dust, 

including crystalline silica, during 

normal mining conditions. Warrior 

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 June 17, 2024, MSHA finalized 

the rule 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 tightfitting respirator. 

(h) Since the 3M Airstream HeadgearMounted PAPR System has been 

discontinued by the manufacturer, there 

are no other MSHA-approved units 

available that can be taken into or used 

inby the last open crosscut or used in 

return air outby the last open crosscut. 

(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 inby the last open 

crosscut or in the return air outby the 

last open crosscut. 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 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 inby 

the last open crosscut or in the 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 used according to the 

original equipment manufacturer’s 

recommendations and 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/ 

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 inby the last open 

crosscut or in the return air outby the 

last open crosscut, 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 the: 

(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
