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 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–2010–005–C. Petitioner: Manalapan Mining Co., Inc., 8174 East Highway 72, Pathfork, Kentucky 40863. Mine: RB #12 Mine, MSHA I.D. No. 15–18771, located in Harlan County, Kentucky. Regulation Affected: 30 CFR 75.507– 1(a) (Electric equipment other than power-connection points; outby the last open crosscut; return air; permissibility requirements). Modification Request: The petitioner requests a modification of the existing standard to permit an increase in the maximum length of trailing cables supplying power to permissible pumps. The petitioner states that: (1) This petition will apply only to trailing cables supplying three-phase, 480-volt power for permissible pumps; (2) the maximum length of 480-volt power for permissible pumps will be 1,800 feet; (3) the 480-volt power for permissible pump trailing cables will be no smaller than #10 American Wire Gauge (AWG); (4) all circuit breakers used to protect trailing cables exceeding the pump approval length or Table 9 of part 18, will have an instantaneous trip unit calibrated to trip at 70% of phase to phase short circuit current. The trip setting of these circuit breakers will be sealed or locked, and these circuit breakers will have permanent, legible labels. Each label will identify the circuit breaker as being suitable for protecting the trailing cables and be E:\FR\FM\17MRN1.SGM 17MRN1 wwoods2 on DSK1DXX6B1PROD with NOTICES_PART 1 12794 Federal Register / Vol. 75, No. 51 / Wednesday, March 17, 2010 / Notices maintained legible. In instances where a 70% instantaneous setpoint will not allow a pump to start, due to motor inrush, a thermal magnetic breaker will be furnished. The thermal rating of the circuit breaker will be no greater than 70% of the available short circuit current and the instantaneous setting will be adjusted to one setting above the motor inrush trip point. This setting will also be sealed or locked; (5) replacement instantaneous trip units, used to protect pump trailing cables exceeding the length of item #4, will be calibrated to trip at 70% of the available phase to phase short circuit current and this setting will be sealed or locked; (6) permanent warning labels will be installed and maintained on the cover(s) of the power center to identify the location of each sealed or locked shortcircuit protection device. These labels will warn miners not to change or alter these short circuit settings; (7) all future pump installations with excessive cable lengths will have a short-circuit survey conducted and items 1–6 will be implemented. A copy of each pump’s short-circuit survey will be available at the mine site for inspection; (8) the petitioner’s alternative method will not be implemented until miners who have been designated to examine the integrity of seals or locks, verify the short-circuit settings, and proper procedures for examining trailing cables for defects and damage have received the elements of training herein; and (9) within sixty (60) days after this petition is granted, proposed revisions for approved 30 CFR Part 48 training plans will be submitted to the District Manager for the area in which the mine is located. The training will include the following elements: (a) Training in mining methods and operating procedures that will protect the trailing cables against damage; (b) training in the proper procedures for examining the trailing cables to ensure the cables are in safe operating condition; (c) training in hazards of setting the instantaneous circuit breakers too high to adequately protect the trailing cables; and (d) training in how to verify the circuit interrupting device(s) protecting the trailing cable(s) are properly set and maintained. The petitioner asserts that the procedures of 30 CFR 48.3 for approval of proposed revisions to already approved training plans will apply, and that the proposed alternative method will at all times guarantee no less than the same measure of protection to all miners at Manalapan Mining Company, Inc., provided by the existing standards. Docket Number: M–2010–006–C. VerDate Nov<24>2008 15:08 Mar 16, 2010 Jkt 220001 Petitioner: Armstrong Coal Company, Inc., 407 Brown Road, Madisonville, Kentucky 42341. Mine: Parkway Mine, MSHA I. D. No. 15–19358, located in Muhlenberg County, Kentucky. Regulation Affected: 30 CFR 75.1101– 1(b) (Deluge-type water spray systems). Modification Request: The petitioner requests a modification of the existing standard to eliminate the requirement that deluge-type water spray system nozzles be provided with blow-off dust covers. The petitioner proposes to conduct weekly examinations and weekly functional testing of the delugetype water spray systems. Specifically, the petitioner proposes that the alternative method consist of the following requirements: (a) Once every seven (7) days, a person trained in the testing procedures specific to the deluge-type water spray systems utilized at each belt drive will: (i) Conduct a visual examination of each of the deluge-type water spray systems; (ii) conduct a functional test of the delugetype water spray systems by actuating the system and observing its performance; and (iii) record the results of the visual examination and functional test in a book maintained on the surface for that purpose. The record will be made available to the authorized representative of the Secretary of Labor (the ‘‘Secretary’’) and retained at the mine for one year; (b) a clogged nozzle or any other malfunction detected as a result of the weekly visual examination and functional test will be corrected immediately; and (c) the procedure used to perform the functional test will be posted at or near each belt drive that utilizes a deluge-type water spray system. The petitioner states that: (1) The alternative method provides for weekly functional testing of the delugetype water spray system while 30 CFR 75.1101–11 requires only yearly functional testing; (2) the alternative method greatly increases frequency of testing, which flushes out the entire system and better assures that the nozzles are not plugged with debris; and (3) eliminating the blow-off dust covers ensures that they do not become corroded and resist blowing off when actuated. The petitioner asserts that the proposed alternative method will all times guarantee no less than the same measure of protection afforded by the existing standard. Docket Number: M–2010–007–C.

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 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.

    Regulation Affected: 30 CFR 75.507-1(a) (Electric equipment other 
than power-connection points; outby the last open crosscut; return air; 
permissibility requirements).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit an increase in the maximum length of 
trailing cables supplying power to permissible pumps. The petitioner 
states that: (1) This petition will apply only to trailing cables 
supplying three-phase, 480-volt power for permissible pumps; (2) the 
maximum length of 480-volt power for permissible pumps will be 1,800 
feet; (3) the 480-volt power for permissible pump trailing cables will 
be no smaller than 10 American Wire Gauge (AWG); (4) all 
circuit breakers used to protect trailing cables exceeding the pump 
approval length or Table 9 of part 18, will have an instantaneous trip 
unit calibrated to trip at 70% of phase to phase short circuit current. 
The trip setting of these circuit breakers will be sealed or locked, 
and these circuit breakers will have permanent, legible labels. Each 
label will identify the circuit breaker as being suitable for 
protecting the trailing cables and be

[[Page 12794]]

maintained legible. In instances where a 70% instantaneous setpoint 
will not allow a pump to start, due to motor inrush, a thermal magnetic 
breaker will be furnished. The thermal rating of the circuit breaker 
will be no greater than 70% of the available short circuit current and 
the instantaneous setting will be adjusted to one setting above the 
motor inrush trip point. This setting will also be sealed or locked; 
(5) replacement instantaneous trip units, used to protect pump trailing 
cables exceeding the length of item 4, will be calibrated to 
trip at 70% of the available phase to phase short circuit current and 
this setting will be sealed or locked; (6) permanent warning labels 
will be installed and maintained on the cover(s) of the power center to 
identify the location of each sealed or locked short-circuit protection 
device. These labels will warn miners not to change or alter these 
short circuit settings; (7) all future pump installations with 
excessive cable lengths will have a short-circuit survey conducted and 
items 1-6 will be implemented. A copy of each pump's short-circuit 
survey will be available at the mine site for inspection; (8) the 
petitioner's alternative method will not be implemented until miners 
who have been designated to examine the integrity of seals or locks, 
verify the short-circuit settings, and proper procedures for examining 
trailing cables for defects and damage have received the elements of 
training herein; and (9) within sixty (60) days after this petition is 
granted, proposed revisions for approved 30 CFR Part 48 training plans 
will be submitted to the District Manager for the area in which the 
mine is located. The training will include the following elements: (a) 
Training in mining methods and operating procedures that will protect 
the trailing cables against damage; (b) training in the proper 
procedures for examining the trailing cables to ensure the cables are 
in safe operating condition; (c) training in hazards of setting the 
instantaneous circuit breakers too high to adequately protect the 
trailing cables; and (d) training in how to verify the circuit 
interrupting device(s) protecting the trailing cable(s) are properly 
set and maintained. The petitioner asserts that the procedures of 30 
CFR 48.3 for approval of proposed revisions to already approved 
training plans will apply, and that the proposed alternative method 
will at all times guarantee no less than the same measure of protection 
to all miners at Manalapan Mining Company, Inc., provided by the 
existing standards.

    Docket Number: M-2010-006-C.
    Petitioner: Armstrong Coal Company, Inc., 407 Brown Road, 
Madisonville, Kentucky 42341.
    Mine: Parkway Mine, MSHA I. D. No. 15-19358, located in Muhlenberg 
County, Kentucky.
    Regulation Affected: 30 CFR 75.1101-1(b) (Deluge-type water spray 
systems).
    Modification Request: The petitioner requests a modification of the 
existing standard to eliminate the requirement that deluge-type water 
spray system nozzles be provided with blow-off dust covers. The 
petitioner proposes to conduct weekly examinations and weekly 
functional testing of the deluge-type water spray systems. 
Specifically, the petitioner proposes that the alternative method 
consist of the following requirements: (a) Once every seven (7) days, a 
person trained in the testing procedures specific to the deluge-type 
water spray systems utilized at each belt drive will: (i) Conduct a 
visual examination of each of the deluge-type water spray systems; (ii) 
conduct a functional test of the deluge-type water spray systems by 
actuating the system and observing its performance; and (iii) record 
the results of the visual examination and functional test in a book 
maintained on the surface for that purpose. The record will be made 
available to the authorized representative of the Secretary of Labor 
(the ``Secretary'') and retained at the mine for one year; (b) a 
clogged nozzle or any other malfunction detected as a result of the 
weekly visual examination and functional test will be corrected 
immediately; and (c) the procedure used to perform the functional test 
will be posted at or near each belt drive that utilizes a deluge-type 
water spray system. The petitioner states that: (1) The alternative 
method provides for weekly functional testing of the deluge-type water 
spray system while 30 CFR 75.1101-11 requires only yearly functional 
testing; (2) the alternative method greatly increases frequency of 
testing, which flushes out the entire system and better assures that 
the nozzles are not plugged with debris; and (3) eliminating the blow-
off dust covers ensures that they do not become corroded and resist 
blowing off when actuated. The petitioner asserts that the proposed 
alternative method will all times guarantee no less than the same 
measure of protection afforded by the existing standard.

furnished. The thermal rating of the circuit breaker will be no greater 
than 75% of the available short-circuit current and the instantaneous 
setting will be adjusted one setting above the motor inrush trip point. 
This setting will also be sealed or locked; (4) replacement 
instantaneous trip units used to protect pump trailing cables exceeding 
the length of item 4 will be calibrated to trip at 75% of the 
available phase to phase short-circuit current and this setting will be 
sealed or locked; (5) permanent warning labels will be installed and 
maintained on the cover(s) of the power center to identify the location 
of each sealed or locked short-circuit protection device. These labels
