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-2022-007-M.
    Petitioner: Nevada Gold Mines, LLC, 1655 Mountain City Highway, 
Elko, Nevada 89801.
    Mine: Twin Underground Mine, MSHA ID No. 26-02693, located in 
Humboldt County, Nevada.
    Regulation Affected: 30 CFR 57.11052(d), Refuge areas.
    Modification Request: The petitioner requests a modification of 30 
CFR 57.11052(d) to permit the use of sealed purified drinking water in 
lieu of providing potable water through waterlines in the existing 
refuge chambers and future refuge chambers and locations.
    The petitioner states that:
    (a) The mine is an underground portal gold mine with five refuge 
chambers located throughout the underground portion of the mine. In the 
refuge areas, drinkable water is supplied via commercially purchased 
water in sealed pouches.
    (b) The refuge chambers are MineARC refuge chambers and are made of 
steel. The five refuge chambers are equipped for a maximum capacity of 
16 miners. This capacity exceeds the normal work crew of approximately 
20 miners underground on any shift.
    (c) Each refuge chamber is provided with a waterline. The water 
flowing through these lines is not potable due to the configuration of 
the waterlines and the water source. Installing waterlines to provide 
potable drinking water to each refuge chamber is not feasible due to 
the lack of essential infrastructure.
    (d) The waterlines are susceptible to damage during an emergency 
and under normal working conditions. The water supply could be cut off 
completely.
    (e) In an emergency, there can be no guarantee of potable drinking 
water via the waterline for miners using the refuge area. Application 
of the standard could adversely impact the safety of the affected 
miners if they were to rely on waterlines running from the portal to 
the refuge chambers, as these lines are subject to interruption and are 
inherently less safe than sanitary sealed water pouches located inside 
the refuge chambers. Sealed water stored inside each refuge chamber 
ensures that affected miners will have sanitary drinking water 
available to them in an emergency.
    (f) The five refuge chambers at the mine are portable. Allowing the 
use of refuge chambers which do not have to be connected to waterlines 
provides greater flexibility in the location of the refuge chambers. 
Refuge chambers can be located in direct relation to where miners are 
working and relocated quickly to working areas as needed for the 
protection of miners.
    The petitioner proposes the following alternative method:
    (a) Drinking water will be supplied via commercially purchased 
water in sealed individual portion-sized pouches in each refuge 
chamber. The water is supplied by the case and packaged into 4.227 
fluid ounce/125 milliliter portions with 50 individual portion sizes 
per case.
    (b) At a minimum, the refuge chamber will be supplied with 2.25 
quarts of water per day per person for 36 hours. The total amount of 
water provided in each refuge chamber will be nine cases of water with 
6.25 liters of water/case.
    (c) The water will have a maximum shelf life of 5 years. The 
operator will replace the existing water supply with fresh water before 
the water's expiration date. The condition and quantity of water will 
be confirmed by inspection on no less than a monthly basis.
    (d) Written instructions for conservation of water will be provided 
with the refuge chamber supplies.

[[Page 18822]]

    (e) All miners affected will receive training in the operation of 
the refuge chamber and will receive refresher training annually.
    (f) The refuge chamber will be inspected monthly and documented by 
the Mine Manager or the Manager's designee.
    The petitioner asserts that the alternative method proposed will at 
all times guarantee no less than the same measure of protection 
afforded the miners under the mandatory standard.
