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, §§ 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 MSHAapproved 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 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 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/

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
