ADDRESSES:
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–2024–002–M.
Petitioner: Northern Star (Pogo), LLC,
3204 International Street, Fairbanks, AK
99702.
VerDate Sep<11>2014
17:26 Oct 03, 2024
Jkt 265001
Mine: Pogo Mine, MSHA ID No. 50–
01642, located in Southeast Fairbanks,
Alaska.
Regulation Affected: 30 CFR
57.11052, Refuge areas.
Modification Request: The petitioner
requests a modification of 30 CFR
57.11052 to allow the use of sealed,
purified drinking water in lieu of
providing potable water through
waterlines in refuge areas.
The petitioner states that:
(a) Pogo Mine is an underground
portal gold mine that began producing
in 2005 and has permitting to continue
mining through 2030.
(b) Pogo Mine currently has 14 refuge
chambers and 10 entrapment chambers
located throughout the underground
portion of the mine. In these purposebuilt refuge chambers, drinkable water
has always been supplied via
commercially purchased water in sealed
bottles. Fire suppression is provided
with fire extinguishers on the exterior
and fire blankets on the interior.
(c) Each refuge chamber cut out is
provided with a waterline. However,
due to the configuration and condition
of the waterlines and the quality of the
water source, the water flowing through
these lines is not potable. Installing
waterlines that provide potable drinking
water to each refuge chamber is not
feasible due to the lack of essential
infrastructure. Given the non-potable
nature of the water and the potential for
waterline damage, there is no guarantee
that potable drinking water can be
provided via the waterlines, as could be
interpreted by 30 CFR57.11052(d).
Application of the standard could
adversely impact the safety of miners
using the refuge if they were to rely on
the waterlines that run throughout the
mine to the refuge chambers. The
alternative method of storing sealed,
purified water inside each refuge
chamber provides certainty that miners
will have sanitary drinking water
available to them, regardless of the
current condition of the water supply or
the nature of any emergency that might
occur in the future.
(d) All refuge and entrapment
chambers at Pogo Mine are portable. By
allowing the use of refuge and
entrapment chambers that are not
connected to waterlines, the mine will
have greater flexibility in the locating of
the chambers. This will allow the
chambers to continue to be located near
where miners are working, and to be
relocated more quickly to working areas
where needed. Additionally, when
damage or corrosion occur in the
waterline connections it has forced the
mine to pull refuge chambers from
service due to water damage internally.
PO 00000
Frm 00105
Fmt 4703
Sfmt 4703

This reduces the number of available
assets in the event of an emergency.
(e) All refuge and entrapment
chambers meet all criteria for safe areas
of refuge to include steel (noncombustible) construction throughout,
large enough to accommodate readily
the normal number of persons in that
area of the mine, constructed so they are
gas tight with positive pressure to expel
potential harmful gasses, and provided
with compressed air lines and suitable
hand tools for getting chambers in
service. Water and stopping materials
are not needed for miners to be
protected during an emergency if they
were to seek refuge per the
manufacturer’s recommendations for
use.
(f) The manufacturer cautions use of
water as potential fire suppression
internally. This should be avoided to
prevent damage and compromise of air
scrubbing units. Standard firefighting
practices also caution that use of water
for firefighting in a sealed enclosed
space would create more hazards from
steam production and arcing of
electronics used, potentially injuring
miners and making the units less safe.
(g) The petitioner proposes that the
Proposed Decision and Order (PDO)
granted by MSHA apply to all existing
refuge chambers and to future refuge
chambers and locations.
(h) The alternative method in the
petition will always guarantee no less
than the same measure of protection
afforded to the miners by the standard.
The petitioner proposes the following
alternative method:
(a) The 14 portable refuge chambers in
use at Pogo Mine are MineARC, Bost,
and DEA refuge chambers and are made
of steel. Each of these portable refuge
chambers is equipped for a capacity of
8 to 20 miners depending on which unit
is in the area. The combined capacity of
the refuge chambers far exceeds the
normal maximum work crew of
approximately 100 miners underground
on any given day during any shift.
(b) Drinking water shall continue to
be supplied via commercially purchased
water in sealed individual portions in
each refuge chamber. The water is
currently supplied by the case and
packaged into 16.9 fluid ounce (500
milliliter) portions with 24 to 30
individual portions per case.
(c) The refuge chambers at the Pogo
Mine are equipped to provide a
minimum of 1.18 gallons (4.5 liters) per
person that the chambers are rated to
hold.
(d) The condition and quantity of
water is confirmed by inspection, on a
regular basis.

(e) Written instructions for
conservation of water shall be provided
with the refuge chamber supplies.
(f) All miners affected shall receive
training in the operation of the refuge
chambers and shall receive refresher
training annually.
(g) The refuge chambers shall be
inspected regularly, with quarterly
inspections and servicing from
manufacturer approved representatives.
These inspections and servicing shall
continue to be documented and
provided to the Mine Manager or their
designee.
