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-2021-004-M.
    Petitioner: Genesis Alkali, LLC, 580 Westvaco Rd., Green River, 
Wyoming (Zip 82935).
    Mine: Genesis Alkali @WESTVACO, MSHA ID No. 48-00152, located in 
Sweetwater County, Wyoming.
    Regulation Affected: 30 CFR 57.22305 (Approved equipment (III 
mines)).
    Modification Request: The petitioner requests a modification of the 
existing 30 CFR 57.22305 standard to permit an alternative, non-MSHA 
approved Powered Air Purifying Respirator (PAPR). The petitioner seeks 
approval for the use of the CleanSpace EX PAPR (CleanSpace EX) in its 
Class III underground, trona mine in areas in or beyond the last open 
crosscut and in areas where methane may enter the air current.
    The petitioner states that:
    (a) Genesis Alkali @WESTVACO is an underground trona mine. The 
petitioner has provided miners who wished to wear a PAPR voluntarily 
with one as a means to provide a fresh air flow over their face in a 
warm environment and to reduce exposure to nuisance dust. Some of the 
miners who choose to wear a PAPR work inby the last open cross cut. The 
petitioner historically purchased 3M Airstream Headgear-Mounted PAPRs. 
3M discontinued these in 2020.
    (b) Other intrinsically safe (IS) respirators available 
commercially have been approved by other certification bodies, e.g., 
European Union and the International Electrotechnical Commission (IEC). 
However, these other IS PAPRs have not been approved by MSHA pursuant 
to 30 CFR parts 18 through 36.
    (c) The CleanSpace EX manufactured by CleanSpace was determined to 
be IS

under other certification bodies. CleanSpace is not pursuing MSHA 
approval.
    (d) The CleanSpace EX's design allows the miners to wear their 
standard head protection, including cap lamps.
    (e) The CleanSpace EX has been tested and approved as IS under many 
internationally recognized testing standards. The CleanSpace EX was 
designed to and is approved pursuant to ATEX ``Equipment or Protective 
System Intended for use in Potentially Explosive Atmospheres Directive 
2014/34/EU'' and is approved to be marked ``I Ml Ex ia I Ma, II 2 G Ex
