Petitioner: United Salt Hockley, LLC, 14002 Warren Ranch Road, Hockley, Texas 77447. Mine: Hockley Mine, MSHA I.D. No. 41–02478, located in Marshall Harris County, Texas. PO 00000 Frm 00060 Fmt 4703 Sfmt 4703 Regulation Affected: 30 CFR 57.4131 (Surface fan installations and mine openings). Modification Request: The petitioner requests that the previously granted petition for modification, Docket Number M–81–41–M be amended for the Hockley Mine, to meet the modern needs of the mine and to clarify the meaning and intent of the modifications. The petitioner states that: (1) The purpose for amending the previously granted petition, docket number M–81–41–M, is to clarify any confusion relating to the location of fire sensors and the equipment used to alert miners to a fire. A strategic location for a fire sensor may change as the mine continues to expand, therefore the petitioner suggests that the consultant review the system and sensor locations every five years and make suggestions for any updates subject to MSHA’s review and approval. (a) Paragraph 1 of the previously granted petition reads as follows: —Fire detection systems shall be installed with sensors at strategic locations throughout the mill building. An alarm indicating the fire location shall be provided in the main shaft hoist house and in the vicinity of the bottom of the first floor stairway to the upper floors. An alarm indicating a mill building fire shall be located in the mine office. The final locations shall be approved by MSHA as an integral part of the mine’s emergency procedures. (b) The petitioner proposes to amend Paragraph 1 to read as follows: —A fire detection system will be installed with sensors at strategic locations throughout the mill building. An annunciator to indicate, at a minimum, the mill building fire location will be provided in the mine office, the main shaft hoist house, and in the vicinity of the bottom of the first floor stairway to the upper floors. Beginning in 2016, a fire protection consultant will be hired every five years to review the fire detection system. MSHA will review and approve any consultant suggestions, and modification or additions will be E:\FR\FM\19AUN1.SGM 19AUN1 mstockstill on DSK3G9T082PROD with NOTICES 55488 Federal Register / Vol. 81, No. 161 / Friday, August 19, 2016 / Notices made an integral part of the mine’s emergency procedures. (2) The purpose of this amendment to the previously granted petition is to clarify the duties of miners once a fire has been detected. This language ensures that certain duties will be performed by trained miners regardless of the working shift or time of day. (a) Paragraph 2 of the previously granted petition reads as follows: —The emergency procedures shall stipulate that all booster and auxiliary fans below ground shall be stopped coincidently with the initiation of a surface fire alarm and attendant stoppage of a main mine fan. (b) The petitioner proposes to amend Paragraph 2 to read as follows: —The Mine Emergency Plan will designate a responsible person for a mining position per shift, and the responsibilities specified will become part of the job duties of any miner assigned to each relevant mining position during their shift. The Mine Emergency Plan will define the responsible person for all shifts and each miner responsible for such a mining position will receive training in their duties as a responsible person in the event of a fire on the surface or in the shaft. In the event of a fire on the surface or in the shaft, a responsible person on the surface will immediately start the escape shaft fan and will stay in attendance at the fan to assure continued operation. Another responsible person will be responsible for stopping all surface fans and for cutting off the electric power to the underground mine. In the event of a mine fire underground, the main mine power and main mine fan controls will be guarded by a responsible person to ensure there are no status changes unless directed by management to make a status change. The power and mine fan may be off or on depending on work activities, thus the status change would affect conditions in the mine that could endanger the miners. This will ensure that no power or ventilation changes that may affect the miner’s safety are made before mine management is able to evaluate the benefits and disadvantages of such changes. The electrical power and fan control locations will be included in the Mine Emergency Plan. The petitioner further states that MSHA investigators conducted a meeting at the mine site, reviewed the petitioner’s proposed amendments to ensure that the proposed alternative method is in compliance with the standard and will at all times guarantee VerDate Sep<11>2014 18:08 Aug 18, 2016 Jkt 238001 no less than the same measure of protection afforded by the standard.

Docket Number: M–2016–005–M. Petitioner: United Salt Hockley, LLC, 14002 Warren Ranch Road, Hockley, Texas 77447. PO 00000 Frm 00062 Fmt 4703 Sfmt 4703 55489 Mine: Hockley Mine, MSHA I.D. No. 41–02478, located in Harris County, Texas. Regulation Affected: 30 CFR 57.4760 (Shaft mines). Modification Request: The petitioner requests that the previously granted petition for modification, Docket Number M–86–1–M be amended for the Hockley Mine, to meet the modern needs of the mine and to clarify the meaning and intent of the modifications. The petitioner states that: (1) The purpose for amending the previously granted petition, docket number M–86–1–M, is to clarify what steps miners will follow in the event there is a loss of power underground. The amendment proposes an additional measure where a responsible person will be designated during each shift based on the mining position’s job duties who will communicate via radio. (a) Paragraph 4 of the previously granted petition reads as follows: —An audible alarm switch shall be located within two (2) intersections from any active mining face or bench face. The alarm switches shall be identified by an electric light and activation of the switches shall energize the mine-wide audible alarms. The sounding of the alarm shall cause the Mine Emergency Plan to be followed immediately. (b) The petitioner proposes to amend Paragraph 4 to read as follows: —An audible alarm switch will be located within two (2) intersections from any active mining face or bench face. The alarm switches will be identified by an electric light and activation of the switches will energize the mine-wide audible alarms. In the event power is lost in the mine or shut-off in response to an emergency situation, miners will immediately begin following the Mine Emergency Plan to evacuate to the refuge chamber, and be alerted via radio communication of an emergency. The sounding of the alarm or any loss of power will cause the Mine Emergency Plan of evacuation to the refuge chamber to be implemented. A responsible person, preferably the lead man on each shift, will be designated in the Mine Emergency Plan to notify the miners via radio communication of an emergency and to instruct all miners to evacuate to the refuge chamber immediately. (2) The purpose of this amendment to the previously granted petition is to allow the evacuation plan to meet the needs of the current mine as old and new corridors are continuously being E:\FR\FM\19AUN1.SGM 19AUN1 mstockstill on DSK3G9T082PROD with NOTICES 55490 Federal Register / Vol. 81, No. 161 / Friday, August 19, 2016 / Notices closed off and created respectively as salt is actively mined. (a) Paragraph 5 of the previously granted petition reads as follows: —The intersections immediately to the west of the refuge chamber (from 11S entry to 8W entry) will be maintained to provide access to the refuge area from the mining areas on the south side of the mine. (b) The petitioner proposes to amend Paragraph 5 to read as follows: — Safe travel ways and escape ways will be marked on the mine map and included in the mine escape and evacuation plan. The travel and escape ways will be updated as necessary to indicate changes as mining areas change. On hour SelfContained Self-Rescuers (SCSR) will be stored in strategic locations which will be detailed in the Mine Emergency Plan and Mine Map. Miners will be trained on proper use of the SCSR’s as required in Part 48. (3) The purpose of this amendment to the previously granted petition is to clarify the miner responsible for certain emergency response activities by assigning these tasks to a mining position. This will ensure that a miner trained for these duties is on-site at all times when the mine is in operation. (a) Paragraph 6 of the previously granted petition reads as follows: —In the event of a fire alarm on the surface, in the shaft, or in the underground mine, a designated person on the surface shall immediately start the borehole fan and stay in attendance at that fan to assure its continued operation. Another designated person shall be responsible for stopping all surface fans and for cutting off the electric power to the underground mine. The electrical power and fan control locations and operational assignments shall be included in the escape and evacuation plan for the mine. (b) The petitioner proposes to amend Paragraph 6 to read as follows: —The Mine Emergency Plan will designate a responsible person for a mining position per shift, and the responsibilities specified will become part of the job duties of any miner assigned to each relevant mining position during their shift. The Mine Emergency Plan will define the responsible person for all shifts and each miner responsible for such a mining position will receive training in their duties as a responsible person in the event of a fire on the surface, in the shaft, or in the underground mine. In the event of a fire alarm on VerDate Sep<11>2014 18:08 Aug 18, 2016 Jkt 238001 the surface or in the shaft, a responsible person on the surface will immediately start the escape shaft fan and will stay in attendance at the fan to assure continued operation. Another responsible person will stop the surface mine fan and cut off the electric power to the underground mine. In the event of a mine fire underground, the main mine power and main mine fan controls will be guarded by a designated miner to ensure there are no status changes unless directed by management to make a status change. The power and mine fan may be off or on depending on work activities, so the status change would affect conditions in the mine that could endanger the miners. This will ensure that no power or ventilation changes that may affect the miner’s safety are made before mine management is able to evaluate the benefits and disadvantage of such changes. The electrical power and fan control locations and operational assignments will be included in the escape and evacuation plan for the mine. (4) The purpose of the amendment to the previously granted petition is to establish communication protocol in the event of a loss of power. (a) Paragraph 7 of the previously granted petition reads as follows: —An emergency alarm siren network will be maintained as the primary warning system of an emergency or fire for personnel in the underground mine. (b) The petitioner proposes to amend Paragraph 7 to read as follows: —An emergency alarm siren network will be maintained as the primary warning system of an emergency or fire for personnel in the underground mine. Radio communication may be used in the event of power loss or intentional power shutdown. Any additional forms of communication and/or warning systems installed in the mine will be included in the Mine Emergency Plan and all miners will receive up-to-date training. (5) The purpose for adding this amendment to the previously granted petition is to further reinforce the fire resistance of the mine fan duct. (a) The petitioner proposes to add Paragraph 8 to the amended petition to read as follows: —The mine fan duct from the mine fan to the shaft collar will be constructed of non-flammable or fire resistant material by December 31, 2016. The petitioner further states that MSHA investigators conducted a PO 00000 Frm 00063 Fmt 4703 Sfmt 4703 meeting at the mine site, reviewed the petitioner’s proposed amendments to ensure that the proposed alternative method is in compliance with the standard and will at all times guarantee no less than the same measure of protection afforded by the standard. Docket Number: M–2016–024–C. Petitioner: Signal Peak Energy, LLC, 100 Portal Drive, Roundup, Montana 59072. Mine: Bull Mountain Mine #1, MSHA I.D. No. 24–01950, located in Musselshell County, Montana. Regulation Affected: 30 CFR 75.312(c) (Main mine fan examinations and records). Modification Request: The petitioner requests a modification of the existing standard to permit fan tests to be performed without shutting the fan down and without removing miners from the mine. The Petitioner states that: (1) Stopping the fan for testing introduces contaminants into the mine atmosphere from the worked out area behind the longwall tailgate. In addition, any delay of a fan restart beyond 15 minutes after shutdown for testing could result in a lengthy restart of the mine operating systems. The petitioner’s alternative method will result in the fan alarm signal being verified by a responsible person at a surface location where the responsible person is always on duty whenever anyone is underground. A report of all tests will be recorded. (2) A valve would be installed in the system monitoring the water gauge of the fan pressure monitoring system. The water gauge installed at the mine is actually a Magnehelic gauge with electronic pickups, which are integrated into the atmospheric monitoring system (AMS). When the valve is closed, the AMS will detect zero fan pressure and activate the alarm. (3) When the fan stoppage signal system is tested, an audible fan signal alarm sounds at the location where a responsible person is on duty, verifying the performance of the fan alarm signal system. The responsible person is provided with two-way communication to working sections and work stations. (4) Every 5 to 7 months, each automatic fan signal device and signal alarm will be tested by stopping the fan to ensure that the automatic signal device causes the alarm to activate when the fan shuts down. (5) The petitioner will notify the District Manager (DM) when the fan is equipped with the fan alarm signal system. This permits MSHA to make an inspection prior to testing the alarm in accordance with the Proposed Decision E:\FR\FM\19AUN1.SGM 19AUN1 Federal Register / Vol. 81, No. 161 / Friday, August 19, 2016 / Notices mstockstill on DSK3G9T082PROD with NOTICES and Order (PDO). If required by the DM, the test procedure will be demonstrated and the fan will be shut down during MSHA’s inspection to verify that the automatic fan signal activates an alarm at the location of the responsible person. (6) Until the fan is equipped in compliance with the PDO, the miners must be removed from the mine for the testing of any fan not yet equipped as required. (7) By the end of the shift on which the test of the automatic fan signal devices is completed, the person(s) performing the test(s) will record the result of test(s) in a secure book. The record book will be retained at a surface location at the mine for at least one year and will be made available for inspection by an authorized representative of the Secretary and the representative of miners. The recordings will also indicate the general repair of the system. (8) Within 60 days of this petition being granted, the petitioner will submit proposed revisions for its approved part 48 training plan to the DM. The revisions will include initial and refresher training regarding compliance with the PDO. (9) Persons who are to perform the tests must be specifically trained on the proper method of testing upon initial assignment to these responsibilities and annually thereafter. The petitioner asserts that the proposed alternative method will at all times guarantee no less the same measure of protection afforded by the standard. Docket Number: M–2016–025–C. Petitioner: Ohio County Coal Company, 1107 Golden Ridge Road, Dallas, West Virginia 26036. Mine: Ohio County Mine, MSHA I.D. No. 46–01436, located in Marshall County, West Virginia.

(3) The under-voltage protection device will operate on a loss-of-voltage to prevent automatic restarting of the equipment. (4) The grounded phase protection device will be provided as follows: (a) The grounded phase protection device will be set not to exceed 40 percent of the current rating of the neutral grounding resistor. (b) The 480-volt circuit will also have an undercurrent relay device to prevent closing the breaker when a phase to ground fault condition exists on the system, and a test circuit that will inject a test current through the grounded phase current transformer. (5) The short-circuit protection device will be set not to exceed the required short-circuit protection for the power cable or 75 percent of the minimum available phase-to-phase short-circuit current, whichever is less. (6) The circuit will include a disconnecting device located on the surface and installed in conjunction with the circuit breaker to provide a means for visual evidence that the power is disconnected from the pump circuits, and a means to lock and tag-out the system. (7) The pump power system will include a fail-safe ground check circuit, or other no less effective device approved by MSHA that will cause the circuit breaker to open when either the ground or pilot wire is broken. A manually operated test switch will be provided to verify the operation ground check device. The device will be installed and maintained operable to monitor the ground continuity from the starter box to the pump. (8) The pump(s) electric control circuit(s) will be designed and installed so that the pump(s) cannot start and/or run in the automatic mode if the water is below the low-water probe level. The low-water probe will be positioned to PO 00000 Frm 00064 Fmt 4703 Sfmt 4703 55491 maintain at least 12 inches above the inlet of the pump and electrical connections of the pump motor. The low-water probe will be suitable for submersible pump control application. All probe circuits will be intrinsically safe. A motor controller will be provided and used for pump startup and shutdown. (9) The pump installation will be equipped with a water level indicator at the pump circuit controls such that a miner can determine the water level is above the pump inlet and electrical connectors. (10) The surface pump(s) control and power circuits will be examined as required by 30 CFR 77.502, as follows: (a) A record of the examinations will be kept in accordance with 30 CFR 77.502 and 77.502–2. (b) The examinations will include a functional test of the grounded phase protective device(s) to determine proper operation. (c) A record of the functional tests will be recorded in an electrical equipment record book. (d) Prior to placing the pump into service an electrical examination will be performed. (e) Methane checks will be made at the collar of the borehole prior to energizing the pump. The pump will not be energized if 1.0 percent or greater of methane is detected. (11) The power cable to the submersible pump motor will be suitable for this application and have a current carrying capacity not less than 125 percent of the full load current of the submersible pump motor and an outer jacket suitable for a ‘‘wet location’’. (12) Splices and connections made in submersible pump cable will be made in a workmanlike manner and will meet the requirements of 30 CFR 75.604. The pump installations will comply with all other applicable 30 CFR requirements. (13) The District Manager (DM) will be notified prior to dewatering any shaft using a nonpermissible submersible pump, and the required shaft plan will include this notification. (14) Within 60 days after this petition for modification is granted, the petitioner will submit proposed revisions for their approved part 48 training plan to the DM. The proposed revisions will specify task training for all qualified electricians who perform electric work and monthly electric examinations as required by 30 CFR 77.502 and refresher training regarding the alternative method outlined in the petition and the terms and conditions stated in the Proposed Decision and E:\FR\FM\19AUN1.SGM 19AUN1 mstockstill on DSK3G9T082PROD with NOTICES 55492 Federal Register / Vol. 81, No. 161 / Friday, August 19, 2016 / Notices Order. The training will include the following elements: (a) The hazards that could exist if the water level falls below the pump inlet or the electric connections of the pump motor. (b) The safe restart procedures, which will include the miner determining that the water level is above the pump inlet and pump motor prior to attempting to establish power and start the pump motor. (15) The procedures of 30 CFR 48.3 for approval of proposed revisions to already approved training plans will apply. The petitioner further states that: 1. Upon completion of excavation/ construction of a shaft, the shaft begins to accumulate water and personnel are never required to go below the collar of the shaft for dewatering purposes. 2. In case there is a blind drilled shaft, the shaft is fully lined with steel casing and is grouted in place. This steel casing and grout seal isolates the completed blind drilled shaft from any coal seams, mitigating any possibility for methane to enter the blind drilled shaft. 3. In the case of a conventionally constructed shaft, ventilation devices are installed to ensure that potential methane accumulations are mitigated. Dewatering significantly minimizes the chance of these devices becoming compromised. The electric motor of any submersible pump is located below the pump intake making it impossible for the motor to be above the surface of the water. 4. Currently there are no electric submersible motor/pump assemblies manufactured that will effectively pump water at the current and future depths of mine workings that are permissible as required by 30 CFR 77.1914(a). 5. The alternative method outlined in this petition is consistent with prudent engineering design pursuant to 30 CFR 77.1900 since it minimizes the hazards to those employed in the initial or subsequent development of the shaft. The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection afforded by the existing standard.

Regulation Affected: 30 CFR 57.11050 (Escapeways and refuges). Modification Request: The petitioner requests relief from the existing standard insofar as it applies to the development and exploration areas of the Kensington Mine. The petitioner states that: (1) Coeur Alaska owns and operates the Kensington Mine, which is an underground gold mine located in Juneau County, Alaska. Kensington utilizes both transverse and longitudinal long-hole stoping. In both methods, a single development drift is driven through waste rock adjacent to the ore body. When this drift reaches planned elevation, level accesses are developed to provide entry points to the ore body for exploration and later ore production. Once the level development and exploration are completed at a planned elevation, the ore is extracted either perpendicular (transverse stoping) or parallel to the strike of the ore (longitudinal stoping). (2) Coeur Alaska seeks a modification stating that during the exploration or development of an ore body within the mine, in order to comply with 30 CFR 57.11050(a), Coeur will not be required to continuously reposition a portable emergency refuge chamber (‘‘refuge’’) on the lowest decline within the mine or to continuously reposition the refuge to remain within 1,000 feet from the face of a development drift. (3) Coeur Alaska seeks relief because Kensington already has secondary escapeways constructed to the lowest level of the mine, and is constructing and planning to develop additional secondary escapeways to future levels of the mine.

SUPPLEMENTARY INFORMATION:

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. That the application of such standard to such mine will result 
in a diminution of safety to the miners in such mine.
    In addition, the regulations at 30 CFR 44.10 and 44.11 establish 
the requirements and procedures for filing petitions for modification.

II. Petitions for Modification

    Docket Number: M-2016-002-M.
    Petitioner: United Salt Hockley, LLC, 14002 Warren Ranch Road, 
Hockley, Texas 77447.
    Mine: Hockley Mine, MSHA I.D. No. 41-02478, located in Marshall 
Harris County, Texas.
    Regulation Affected: 30 CFR 57.4131 (Surface fan installations and 
mine openings).
    Modification Request: The petitioner requests that the previously 
granted petition for modification, Docket Number M-81-41-M be amended 
for the Hockley Mine, to meet the modern needs of the mine and to 
clarify the meaning and intent of the modifications. The petitioner 
states that:
    (1) The purpose for amending the previously granted petition, 
docket number M-81-41-M, is to clarify any confusion relating to the 
location of fire sensors and the equipment used to alert miners to a 
fire. A strategic location for a fire sensor may change as the mine 
continues to expand, therefore the petitioner suggests that the 
consultant review the system and sensor locations every five years and 
make suggestions for any updates subject to MSHA's review and approval.
    (a) Paragraph 1 of the previously granted petition reads as 
follows:

--Fire detection systems shall be installed with sensors at strategic 
locations throughout the mill building. An alarm indicating the fire 
location shall be provided in the main shaft hoist house and in the 
vicinity of the bottom of the first floor stairway to the upper floors. 
An alarm indicating a mill building fire shall be located in the mine 
office. The final locations shall be approved by MSHA as an integral 
part of the mine's emergency procedures.

    (b) The petitioner proposes to amend Paragraph 1 to read as 
follows:

--A fire detection system will be installed with sensors at strategic 
locations throughout the mill building. An annunciator to indicate, at 
a minimum, the mill building fire location will be provided in the mine 
office, the main shaft hoist house, and in the vicinity of the bottom 
of the first floor stairway to the upper floors. Beginning in 2016, a 
fire protection consultant will be hired every five years to review the 
fire detection system. MSHA will review and approve any consultant 
suggestions, and modification or additions will be

[[Page 55488]]

made an integral part of the mine's emergency procedures.

    (2) The purpose of this amendment to the previously granted 
petition is to clarify the duties of miners once a fire has been 
detected. This language ensures that certain duties will be performed 
by trained miners regardless of the working shift or time of day.
    (a) Paragraph 2 of the previously granted petition reads as 
follows:

--The emergency procedures shall stipulate that all booster and 
auxiliary fans below ground shall be stopped coincidently with the 
initiation of a surface fire alarm and attendant stoppage of a main 
mine fan.

    (b) The petitioner proposes to amend Paragraph 2 to read as 
follows:

--The Mine Emergency Plan will designate a responsible person for a 
mining position per shift, and the responsibilities specified will 
become part of the job duties of any miner assigned to each relevant 
mining position during their shift. The Mine Emergency Plan will define 
the responsible person for all shifts and each miner responsible for 
such a mining position will receive training in their duties as a 
responsible person in the event of a fire on the surface or in the 
shaft. In the event of a fire on the surface or in the shaft, a 
responsible person on the surface will immediately start the escape 
shaft fan and will stay in attendance at the fan to assure continued 
operation. Another responsible person will be responsible for stopping 
all surface fans and for cutting off the electric power to the 
underground mine. In the event of a mine fire underground, the main 
mine power and main mine fan controls will be guarded by a responsible 
person to ensure there are no status changes unless directed by 
management to make a status change. The power and mine fan may be off 
or on depending on work activities, thus the status change would affect 
conditions in the mine that could endanger the miners. This will ensure 
that no power or ventilation changes that may affect the miner's safety 
are made before mine management is able to evaluate the benefits and 
disadvantages of such changes. The electrical power and fan control 
locations will be included in the Mine Emergency Plan.

    The petitioner further states that MSHA investigators conducted a 
meeting at the mine site, reviewed the petitioner's proposed amendments 
to ensure that the proposed alternative method is in compliance with 
the standard and will at all times guarantee no less than the same 
measure of protection afforded by the standard.

    Docket Number: M-2016-003-M.
    Petitioner: United Salt Hockley, LLC, 14002 Warren Ranch Road, 
Hockley, Texas 77447.
    Mine: Hockley Mine, MSHA I.D. No. 41-02478, located in Harris 
County, Texas.
    Regulation Affected: 30 CFR 57.4560 (Mine entrances).
    Modification Request: The petitioner requests that the previously 
granted petition for modification, Docket Number M-81-42-M be amended 
for the Hockley Mine, to meet the modern needs of the mine and to 
clarify the meaning and intent of the modifications. The petitioner 
states that:
    (1) The purpose for amending the previously granted petition, 
docket number M-81-42-M, is to clarify any confusion relating to the 
location of fire sensors and the equipment used to alert miners to a 
fire. A strategic location for a fire sensor may change as the mine

[[Page 55489]]

    Petitioner: United Salt Hockley, LLC, 14002 Warren Ranch Road, 
Hockley, Texas 77447.
    Mine: Hockley Mine, MSHA I.D. No. 41-02478, located in Harris 
County, Texas.
    Regulation Affected: 30 CFR 57.4533 (Mine opening vicinity).
    Modification Request: The petitioner requests that the previously 
granted petition for modification, Docket Number M-81-43-M be amended 
for the Hockley Mine, to meet the modern needs of the mine and to 
clarify the meaning and intent of the modifications. The petitioner 
states that:
    (1) The purpose for amending the previously granted petition,

An alarm indicating a mill building fire shall be located in the mine 
office. The final locations shall be approved by MSHA as an integral 
part of the mine's emergency procedures.

    (b) The petitioner proposes to amend Paragraph 1 to read as 
follows:

--A fire detection system will be installed with sensors at strategic 
locations throughout the mill building. An annunciator indicating at a 
minimum the fire location, will be provided in the mill building, the 
mine office, the main shaft hoist house, and in the vicinity of the

detected. This language ensures that certain duties will be performed 
by trained miners regardless of the working shift or time of day.
    (a) Paragraph 2 of the previously granted petition reads as 
follows:

--The emergency procedures shall stipulate that all booster and

--The Mine Emergency Plan will designate a responsible person for a 
mining position per shift, and the responsibilities specified will 
become part of the job duties of any miner assigned to each relevant 
mining position during their shift. The Mine Emergency Plan will define 
the responsible person for all shifts and each miner responsible for

    Docket Number: M-2016-005-M.
    Petitioner: United Salt Hockley, LLC, 14002 Warren Ranch Road, 
Hockley, Texas 77447.
    Mine: Hockley Mine, MSHA I.D. No. 41-02478, located in Harris 
County, Texas.
    Regulation Affected: 30 CFR 57.4760 (Shaft mines).
    Modification Request: The petitioner requests that the previously 
granted petition for modification, Docket Number M-86-1-M be amended 
for the Hockley Mine, to meet the modern needs of the mine and to 
clarify the meaning and intent of the modifications. The petitioner 
states that:
    (1) The purpose for amending the previously granted petition, 
docket number M-86-1-M, is to clarify what steps miners will follow in 
the event there is a loss of power underground. The amendment proposes 
an additional measure where a responsible person will be designated 
during each shift based on the mining position's job duties who will 
communicate via radio.
    (a) Paragraph 4 of the previously granted petition reads as 
follows:

--An audible alarm switch shall be located within two (2) intersections 
from any active mining face or bench face. The alarm switches shall be 
identified by an electric light and activation of the switches shall 
energize the mine-wide audible alarms. The sounding of the alarm shall 
cause the Mine Emergency Plan to be followed immediately.

    (b) The petitioner proposes to amend Paragraph 4 to read as 
follows:

--An audible alarm switch will be located within two (2) intersections 
from any active mining face or bench face. The alarm switches will be 
identified by an electric light and activation of the switches will 
energize the mine-wide audible alarms. In the event power is lost in 
the mine or shut-off in response to an emergency situation, miners will 
immediately begin following the Mine Emergency Plan to evacuate to the 
refuge chamber, and be alerted via radio communication of an emergency. 
The sounding of the alarm or any loss of power will cause the Mine 
Emergency Plan of evacuation to the refuge chamber to be implemented. A 
responsible person, preferably the lead man on each shift, will be 
designated in the Mine Emergency Plan to notify the miners via radio 
communication of an emergency and to instruct all miners to evacuate to 
the refuge chamber immediately.

    (2) The purpose of this amendment to the previously granted 
petition is to allow the evacuation plan to meet the needs of the 
current mine as old and new corridors are continuously being

[[Page 55490]]

closed off and created respectively as salt is actively mined.
    (a) Paragraph 5 of the previously granted petition reads as 
follows:

--The intersections immediately to the west of the refuge chamber (from 
11S entry to 8W entry) will be maintained to provide access to the 
refuge area from the mining areas on the south side of the mine.

    (b) The petitioner proposes to amend Paragraph 5 to read as 
follows:

-- Safe travel ways and escape ways will be marked on the mine map and 
included in the mine escape and evacuation plan. The travel and escape 
ways will be updated as necessary to indicate changes as mining areas 
change. On hour Self-Contained Self-Rescuers (SCSR) will be stored in 
strategic locations which will be detailed in the Mine Emergency Plan 
and Mine Map. Miners will be trained on proper use of the SCSR's as 
required in Part 48.

    (3) The purpose of this amendment to the previously granted 
petition is to clarify the miner responsible for certain emergency 
response activities by assigning these tasks to a mining position. This 
will ensure that a miner trained for these duties is on-site at all 
times when the mine is in operation.
    (a) Paragraph 6 of the previously granted petition reads as 
follows:

--In the event of a fire alarm on the surface, in the shaft, or in the 
underground mine, a designated person on the surface shall immediately 
start the borehole fan and stay in attendance at that fan to assure its 
continued operation. Another designated person shall be responsible for 
stopping all surface fans and for cutting off the electric power to the 
underground mine. The electrical power and fan control locations and 
operational assignments shall be included in the escape and evacuation 
plan for the mine.

    (b) The petitioner proposes to amend Paragraph 6 to read as 
follows:

--The Mine Emergency Plan will designate a responsible person for a 
mining position per shift, and the responsibilities specified will 
become part of the job duties of any miner assigned to each relevant 
mining position during their shift. The Mine Emergency Plan will define 
the responsible person for all shifts and each miner responsible for 
such a mining position will receive training in their duties as a 
responsible person in the event of a fire on the surface, in the shaft, 
or in the underground mine. In the event of a fire alarm on the surface 
or in the shaft, a responsible person on the surface will immediately 
start the escape shaft fan and will stay in attendance at the fan to 
assure continued operation. Another responsible person will stop the 
surface mine fan and cut off the electric power to the underground 
mine. In the event of a mine fire underground, the main mine power and 
main mine fan controls will be guarded by a designated miner to ensure 
there are no status changes unless directed by management to make a 
status change. The power and mine fan may be off or on depending on 
work activities, so the status change would affect conditions in the 
mine that could endanger the miners. This will ensure that no power or 
ventilation changes that may affect the miner's safety are made before 
mine management is able to evaluate the benefits and disadvantage of 
such changes. The electrical power and fan control locations and 
operational assignments will be included in the escape and evacuation 
plan for the mine.

    (4) The purpose of the amendment to the previously granted petition 
is to establish communication protocol in the event of a loss of power.
    (a) Paragraph 7 of the previously granted petition reads as 
follows:

--An emergency alarm siren network will be maintained as the primary 
warning system of an emergency or fire for personnel in the underground 
mine.

    (b) The petitioner proposes to amend Paragraph 7 to read as 
follows:

--An emergency alarm siren network will be maintained as the primary 
warning system of an emergency or fire for personnel in the underground 
mine. Radio communication may be used in the event of power loss or 
intentional power shutdown. Any additional forms of communication and/
or warning systems installed in the mine will be included in the Mine 
Emergency Plan and all miners will receive up-to-date training.

    (5) The purpose for adding this amendment to the previously granted 
petition is to further reinforce the fire resistance of the mine fan 
duct.
    (a) The petitioner proposes to add Paragraph 8 to the amended 
petition to read as follows:

--The mine fan duct from the mine fan to the shaft collar will be 
constructed of non-flammable or fire resistant material by December 31, 
2016.

    The petitioner further states that MSHA investigators conducted a 
meeting at the mine site, reviewed the petitioner's proposed amendments 
to ensure that the proposed alternative method is in compliance with 
the standard and will at all times guarantee no less than the same 
measure of protection afforded by the standard.
    Docket Number: M-2016-024-C.
    Petitioner: Signal Peak Energy, LLC, 100 Portal Drive, Roundup, 
Montana 59072.
    Mine: Bull Mountain Mine #1, MSHA I.D. No. 24-01950, located in 
Musselshell County, Montana.
    Regulation Affected: 30 CFR 75.312(c) (Main mine fan examinations 
and records).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit fan tests to be performed without shutting 
the fan down and without removing miners from the mine. The Petitioner 
states that:
    (1) Stopping the fan for testing introduces contaminants into the 
mine atmosphere from the worked out area behind the longwall tailgate. 
In addition, any delay of a fan restart beyond 15 minutes after 
shutdown for testing could result in a lengthy restart of the mine 
operating systems. The petitioner's alternative method will result in 
the fan alarm signal being verified by a responsible person at a 
surface location where the responsible person is always on duty 
whenever anyone is underground. A report of all tests will be recorded.
    (2) A valve would be installed in the system monitoring the water 
gauge of the fan pressure monitoring system. The water gauge installed 
at the mine is actually a Magnehelic gauge with electronic pickups, 
which are integrated into the atmospheric monitoring system (AMS). When 
the valve is closed, the AMS will detect zero fan pressure and activate 
the alarm.
    (3) When the fan stoppage signal system is tested, an audible fan 
signal alarm sounds at the location where a responsible person is on 
duty, verifying the performance of the fan alarm signal system. The 
responsible person is provided with two-way communication to working 
sections and work stations.
    (4) Every 5 to 7 months, each automatic fan signal device and 
signal alarm will be tested by stopping the fan to ensure that the 
automatic signal device causes the alarm to activate when the fan shuts 
down.
    (5) The petitioner will notify the District Manager (DM) when the 
fan is equipped with the fan alarm signal system. This permits MSHA to 
make an inspection prior to testing the alarm in accordance with the 
Proposed Decision

[[Page 55491]]

and Order (PDO). If required by the DM, the test procedure will be 
demonstrated and the fan will be shut down during MSHA's inspection to 
verify that the automatic fan signal activates an alarm at the location 
of the responsible person.
    (6) Until the fan is equipped in compliance with the PDO, the 
miners must be removed from the mine for the testing of any fan not yet 
equipped as required.
    (7) By the end of the shift on which the test of the automatic fan 
signal devices is completed, the person(s) performing the test(s) will 
record the result of test(s) in a secure book. The record book will be 
retained at a surface location at the mine for at least one year and 
will be made available for inspection by an authorized representative 
of the Secretary and the representative of miners. The recordings will 
also indicate the general repair of the system.
    (8) Within 60 days of this petition being granted, the petitioner 
will submit proposed revisions for its approved part 48 training plan 
to the DM. The revisions will include initial and refresher training 
regarding compliance with the PDO.
    (9) Persons who are to perform the tests must be specifically 
trained on the proper method of testing upon initial assignment to 
these responsibilities and annually thereafter.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less the same measure of protection afforded by 
the standard.

    Docket Number: M-2016-025-C.
    Petitioner: Ohio County Coal Company, 1107 Golden Ridge Road, 
Dallas, West Virginia 26036.
    Mine: Ohio County Mine, MSHA I.D. No. 46-01436, located in Marshall 
County, West Virginia.
    Regulation Affected: 30 CFR 77.1914(a) (Electrical equipment).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the use of 480-volt, three-phase, 
alternating current submersible pumps to dewater completed ventilation 
shafts prior to being put into service. The petitioner states that:
    (1) The three-phase, 480-volt alternating current electric power 
circuit for the pump will be designed and installed to:
    (a) Contain either a direct or derived neutral wire that will be 
grounded through a suitable resistor at the source transformer or power 
center and through a grounding circuit originating at the ground side 
of the grounding resistor, which will extend along with the power 
conductor and serve as the grounding conductor for the frame of the 
pump and all associated electric equipment that may be supplied power 
from this circuit.
    (b) Contain a grounding resistor that limits the ground-fault 
current to not more than 25 amperes.
    (c) The grounding resistor(s) will be rated for the maximum fault 
current available and will be insulated from ground for a voltage equal 
to the phase-to-phase voltage of the system.
    (2) The 480-volt pump circuit will have a suitable circuit 
interrupting device of adequate interrupting capacity, with devices to 
protect against under-voltage, grounded phase, short-circuit, and 
overload.
    (3) The under-voltage protection device will operate on a loss-of-
voltage to prevent automatic restarting of the equipment.
    (4) The grounded phase protection device will be provided as 
follows:
    (a) The grounded phase protection device will be set not to exceed 
40 percent of the current rating of the neutral grounding resistor.
    (b) The 480-volt circuit will also have an undercurrent relay 
device to prevent closing the breaker when a phase to ground fault 
condition exists on the system, and a test circuit that will inject a 
test current through the grounded phase current transformer.
    (5) The short-circuit protection device will be set not to exceed 
the required short-circuit protection for the power cable or 75 percent 
of the minimum available phase-to-phase short-circuit current, 
whichever is less.
    (6) The circuit will include a disconnecting device located on the 
surface and installed in conjunction with the circuit breaker to 
provide a means for visual evidence that the power is disconnected from 
the pump circuits, and a means to lock and tag-out the system.
    (7) The pump power system will include a fail-safe ground check 
circuit, or other no less effective device approved by MSHA that will 
cause the circuit breaker to open when either the ground or pilot wire 
is broken. A manually operated test switch will be provided to verify 
the operation ground check device. The device will be installed and 
maintained operable to monitor the ground continuity from the starter 
box to the pump.
    (8) The pump(s) electric control circuit(s) will be designed and 
installed so that the pump(s) cannot start and/or run in the automatic 
mode if the water is below the low-water probe level. The low-water 
probe will be positioned to maintain at least 12 inches above the inlet 
of the pump and electrical connections of the pump motor. The low-water 
probe will be suitable for submersible pump control application. All 
probe circuits will be intrinsically safe. A motor controller will be 
provided and used for pump startup and shutdown.
    (9) The pump installation will be equipped with a water level 
indicator at the pump circuit controls such that a miner can determine 
the water level is above the pump inlet and electrical connectors.
    (10) The surface pump(s) control and power circuits will be 
examined as required by 30 CFR 77.502, as follows:
    (a) A record of the examinations will be kept in accordance with 30 
CFR 77.502 and 77.502-2.
    (b) The examinations will include a functional test of the grounded 
phase protective device(s) to determine proper operation.
    (c) A record of the functional tests will be recorded in an 
electrical equipment record book.
    (d) Prior to placing the pump into service an electrical 
examination will be performed.
    (e) Methane checks will be made at the collar of the borehole prior 
to energizing the pump. The pump will not be energized if 1.0 percent 
or greater of methane is detected.
    (11) The power cable to the submersible pump motor will be suitable 
for this application and have a current carrying capacity not less than 
125 percent of the full load current of the submersible pump motor and 
an outer jacket suitable for a ``wet location''.
    (12) Splices and connections made in submersible pump cable will be 
made in a workmanlike manner and will meet the requirements of 30 CFR 
75.604. The pump installations will comply with all other applicable 30 
CFR requirements.
    (13) The District Manager (DM) will be notified prior to dewatering 
any shaft using a nonpermissible submersible pump, and the required 
shaft plan will include this notification.
    (14) Within 60 days after this petition for modification is 
granted, the petitioner will submit proposed revisions for their 
approved part 48 training plan to the DM. The proposed revisions will 
specify task training for all qualified electricians who perform 
electric work and monthly electric examinations as required by 30 CFR 
77.502 and refresher training regarding the alternative method outlined 
in the petition and the terms and conditions stated in the Proposed 
Decision and

[[Page 55492]]

Order. The training will include the following elements:
    (a) The hazards that could exist if the water level falls below the 
pump inlet or the electric connections of the pump motor.
    (b) The safe restart procedures, which will include the miner 
determining that the water level is above the pump inlet and pump motor 
prior to attempting to establish power and start the pump motor.
    (15) The procedures of 30 CFR 48.3 for approval of proposed 
revisions to already approved training plans will apply.
    The petitioner further states that:
    1. Upon completion of excavation/construction of a shaft, the shaft 
begins to accumulate water and personnel are never required to go below 
the collar of the shaft for dewatering purposes.
    2. In case there is a blind drilled shaft, the shaft is fully lined 
with steel casing and is grouted in place. This steel casing and grout 
seal isolates the completed blind drilled shaft from any coal seams, 
mitigating any possibility for methane to enter the blind drilled 
shaft.
    3. In the case of a conventionally constructed shaft, ventilation 
devices are installed to ensure that potential methane accumulations 
are mitigated. Dewatering significantly minimizes the chance of these 
devices becoming compromised. The electric motor of any submersible 
pump is located below the pump intake making it impossible for the 
motor to be above the surface of the water.
    4. Currently there are no electric submersible motor/pump 
assemblies manufactured that will effectively pump water at the current 
and future depths of mine workings that are permissible as required by 
30 CFR 77.1914(a).
    5. The alternative method outlined in this petition is consistent 
with prudent engineering design pursuant to 30 CFR 77.1900 since it 
minimizes the hazards to those employed in the initial or subsequent 
development of the shaft.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the existing standard.
