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-2023-002-M.
    Petitioner: U.S. Silica Company, 4800 Oklahoma Hwy 1 North, Mill 
Creek, Oklahoma 74856.
    Mine: Mill Creek Plant #37, MSHA ID No. 34-00377, located in 
Johnston County, Oklahoma.
    Regulation Affected: 30 CFR 56.13020 (Use of compressed air).
    Modification Request: The petitioner requests a modification of 30 
CFR 56.13020 to allow compressed air to be directed towards persons for 
use in a clothes cleaning booth.
    The petitioner states that:
    (a) The petitioner proposes to implement a clothes cleaning 
process.
    (b) The alternative method provides a direct reduction of a miners' 
exposures to respirable dust, thus reducing their health risks.
    (c) The proposed alternative method has been developed jointly 
between Unimin Corporation and the National Institute for Occupational 
Safety and Health (NIOSH) and has been successfully tested by NIOSH.
    The petitioner proposes the following alternative method:
    (a) The petitioner will use a clothes cleaning booth, CCB Elite I, 
serial number 5406, manufactured by S.K. Bowling, Inc.
    (b) Only miners trained in the operation of the clothes cleaning 
booth (booth) will be permitted to use the booth to clean their 
clothes.
    (c) The petitioner will incorporate the NIOSH Clothes Cleaning 
Process and

[[Page 34548]]

manufacturer's instruction manuals into their MSHA part 46 training 
plan and train affected miners in the process.
    (d) Miners entering the booth shall examine valves and nozzles for 
damage or malfunction and will close the door fully before opening the 
air valve. Any defects shall be repaired prior to the booth being used.
    (e) Miners entering the booth shall wear eye protection, ear plugs 
or muffs for hearing protection, and respiratory protection meaning a 
full-face or half-mask respirator that meets or exceeds the minimum 
requirements of an N95 filter to which the miner has been fit-tested. 
As an alternative, the use of a full-face respirator will also meet the 
requirement for eye protection. A sign will be conspicuously posted 
that states the above personal protective equipment is required when 
entering the booth.
    (f) Air flow through the booth will be at least 2,000 cubic feet 
per minute (cfm) to maintain negative pressure during the use of the 
cleaning system in order to prevent contamination of the environment 
outside the booth. Airflow will be in a downward direction, thereby 
moving contaminants away from the miner's breathing zone.
    (g) Air pressure through the spray manifold will be limited to 30 
pounds per square inch or less. A lock box with a single, plant 
manager-controlled key will be used to prevent regulator tampering.
    (h) The spray manifold will consist of a 2-inch square tube with 
\1/4\ inch wall thickness, capped at the base and actuated by an 
electrically controlled valve at the top.
    (i) Air nozzles shall not exceed 30 pound(s) per square inch gauge.
    (j) The uppermost spray of the spray manifold will be located below 
the booth user's breathing zone. Some type of mechanical device can be 
used to cover the upper air nozzles to meet the specific height of the 
user.
    (k) Air nozzles shall be guarded to eliminate the possibility of 
incidental contact, which could create mechanical damage to the air 
nozzles during the clothes cleaning process.
    (l) The petitioner shall conduct periodic maintenance checks of the 
booth in accordance with the recommendations contained in the 
manufacturer's instruction manual.
    (m) The air receiver tank supplying air to the manifold system will 
be of sufficient volume to permit no less than 20 seconds of continuous 
cleaning time.
    (n) An appropriate hazard warning sign will be posted on the booth 
to state, at a minimum, ``Compressed Air'' and ``Respirable Dust.''
    (o) A pressure relief valve designed for the booth's air reservoir 
will be installed.
    (p) The mine will exhaust dust-laden air from the booth into a 
local exhaust ventilation system or duct outside the facility while 
ensuring there is no re-entrainment back into the structure.
    In support of the proposed alternative method, the petitioner 
submitted specifications of the dust booth; installation and operating 
instructions of the dust booth to be used; and The Dust Control 
Handbook for Industrial Minerals, Mining, and Processing.
    The petitioner asserts that the alternate method proposed will at 
all times guarantee no less than the same measure of protection 
afforded the miners under the mandatory standard.
