Petitioner: Kingston Mining, Inc., Route 1, Box 76–C, Scarbro, West Virginia 25917. Mine: Kingston No. 1 Mine, MSHA I.D. No. 46–08625, located in Fayette County, West Virginia. 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 permit deluge-type water spray systems to be used without blowoff dust covers on the nozzles. The petitioner states that: (1) Weekly inspections and functional tests of its complete deluge-type water spray system are currently being conducted at the mine; (2) each nozzle is provided with a blow-off dust cover; (3) due to frequent inspections and functional testing of the system, the dust covers are not necessary because the nozzles can be maintained in an unclogged condition through weekly use; and (4) it is burdensome to recap the large number of covers weekly after each inspection and functional test. The petitioner proposes to continue its weekly inspection and functional testing of the complete deluge-type water spray system at the Kingston No. 1 Mine, and to remove the blow-off dust covers from the nozzles. The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection afforded the miners as would be provided by the existing standard. Docket Number: M–2010–041–C. Petitioner: Twentymile Coal LLC, Three Gateway Center, Suite 1340, 401 Liberty Avenue, Pittsburgh, Pennsylvania 15222–1000. Mine: Foidel Creek Mine, MSHA I.D.

The petitioner states: (1) Only miners trained in the operation of the NIOSH-tested clothes cleaning booth process will be permitted to use the process. (2) Clothes cleaning booth process training will be incorporated into the Part 46 training plan. (3) All miners entering the NIOSH-tested clothes cleaning booth will be required to wear full seal goggles for eye protection, ear plugs or muffs for hearing protection, and fit-tested respirators with N100 filters for VerDate Mar<15>2010 16:17 Mar 23, 2011 Jkt 223001 respiratory protection. (4) The clothes cleaning booth will have a caution sign, conspicuously posted, indicating that the use of respirators, hearing protection, and goggles are required before entering the booth. (5) Air pressure through the spray manifold will be limited to 30 pounds per square inch. A lock-box with a single key controlled by the Plant Manager will be used to prevent tampering with the regulator. (6) The air spray manifold will consist of 1.5 inch schedule 80 pipe, which has a failure pressure of 1,300 pounds per square inch, capped at the base and actuated by an electricallycontrolled ball valve at the top. (7) The air spray manifold will contain 26 total nozzles of which 25 will be 18.4 SCFM @ 3 psig and the 26th and lowermost nozzle will be 19.2 SCFM @ 30 psig. (8) The uppermost spray nozzle will be located at a height of not more than 56 inches. Those miners with a shoulder height less than 56 inches will use mechanical air spray deflectors, which are quick, effective, and easy to use. (9) Miners will be use side deflectors to eliminate the possibility of incidental contact with the air nozzles during use of the clothes cleaning booth. (10) Spraying Systems Company Nozzle No. AA727–23 contains a recessed design to provide air escape should the nozzle be accidentally placed against a surface. (11) An electrically actuated valve will be inter-locked into the bag house dust collector to prevent use of the clothes cleaning booth if the dust collection system is not functioning or inoperable. (12) The clothes cleaning booth will be fitted with a stand-alone dust collection system. (13) Airflow through the clothes cleaning booth will be sufficient to maintain negative pressure during its use in order to prevent contamination of the environment outside of the booth. (14) The air receiver tank supplying air to the manifold system will be of sufficient volume to permit not less than 20 seconds of continuous cleaning time. (15) Airflow through the booth will be in the downward direction, thereby moving contaminants away from the miner’s breathing zone. (16) Miners entering the clothes cleaning booth will perform regular user checks examining the valves and nozzle for damage of malfunction and ensure that the door is fully closed before opening the air valve. (17) Periodic maintenance checks will be performed in accordance with the NIOSH recommendation contained within the ‘‘Clothes Cleaning Process Instruction Manual.’’ No significant safety or health concerns have been identified because the eyes are protected by full seal goggles, the skin is protected PO 00000 Frm 00047 Fmt 4703 Sfmt 4703 16643 by work clothes, hearing is protected by plugs or muffs, and the lungs are protected by a respirator, and air is limited to 30 pounds per square inch, which is the Occupational Safety and Health Administration (OSHA) limit for cleaning purposes. The petitioner asserts that the cleaning process will provide a more effective clothes cleaning method and a direct reduction of a miners’ exposure to respirable crystalline silica dust, thus reducing their health risks while providing no less a degree of safety than that provided by the standard.

10 American Wire Gauge (AWG) cable (SO cable) with a diameter of 0.77 
with a tolerance of +/- 0.03. The petitioner states that: (1) The cable 
will be hung on insulated hangers for the entire length at all times; 
(2) within 60 days after the proposed decision and order becomes final, 
proposed revisions for its approved 30 CFR part 48 training plan will 
be submitted to the District Manager. In addition, the proposed 
revisions will specify initial and refresher training regarding the 
terms and conditions stated in the proposed decision and order. The 
petitioner asserts that the proposed alternative method will at all 
times guarantee no less than the same measure of protection afforded by 
the standard.

    Docket Number: M-2011-003-C.
    Petitioner: Frasure Creek Mining, LLC, P.O. Box 142, Justice, West 
Virginia 24851.
    Mine: Deep Mine No. 11, MSHA I.D. No. 46-09329, located in Fayette 
County, West Virginia, and Isaban Deep Mine No. 3, MSHA I.D. No. 46-
09245, located in Mingo County, West Virginia.
    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 use of blow-off dust covers for the 
spray nozzles of a deluge-type water spray system. The petitioner 
proposes to conduct a weekly inspection and functional test of its 
complete deluge-type spray system. The petitioner states that: (1) The 
system consists of an average of thirty (30) sprays along each of 
approximately ten (10) primary belt-conveyor drives and an average of 
sixty (60) sprays along each of eight (8) secondary drives; (2) the 
nozzles are currently provided with blow-off dust covers, but the dust 
covers are not necessary because the nozzles can be maintained in an 
unclogged condition through weekly use; and (3) it is burdensome to 
recap the large number of covers weekly after each inspection and 
functional test. The petitioner asserts that the proposed alternative 
method will at all times guarantee no less than the same measure of 
protection afforded the miners than the existing standard.
    Docket Number: M-2011-001-M.
    Petitioner: Carmeuse Industrial Sands, P.O. Box 429, Brady, Texas 
76825.
    Mine: Brady Plant, MSHA I.D. No. 41-01371, located in McCulloch 
County, Texas.
    Regulation Affected: 30 CFR 56.13020 (Use of compressed air).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the implementation of a clothes cleaning 
booth process that has been jointly developed with and successfully 
tested by the National Institute for Occupational Safety and Health 
(NIOSH). This process utilizes controlled compressed air for the 
purpose of cleaning miners' dust laden clothing. The petitioner states: 
(1) Only miners trained in the operation of the NIOSH-tested clothes 
cleaning booth process will be permitted to use the process. (2) 
Clothes cleaning booth process training will be incorporated into the 
Part 46 training plan. (3) All miners entering the NIOSH-tested clothes 
cleaning booth will be required to wear full seal goggles for eye 
protection, ear plugs or muffs for hearing protection, and fit-tested 
respirators with N100 filters for respiratory protection. (4) The 
clothes cleaning booth will have a caution sign, conspicuously posted, 
indicating that the use of respirators, hearing protection, and goggles 
are required before entering the booth. (5) Air pressure through the 
spray manifold will be limited to 30 pounds per square inch. A lock-box 
with a single key controlled by the Plant Manager will be used to 
prevent tampering with the regulator. (6) The air spray manifold will 
consist of 1.5 inch schedule 80 pipe, which has a failure pressure of 
1,300 pounds per square inch, capped at the base and actuated by an 
electrically-controlled ball valve at the top. (7) The air spray 
manifold will contain 26 total nozzles of which 25 will be 18.4 SCFM @ 
3 psig and the 26th and lowermost nozzle will be 19.2 SCFM @ 30 psig. 
(8) The uppermost spray nozzle will be located at a height of not more 
than 56 inches. Those miners with a shoulder height less than 56 inches 
will use mechanical air spray deflectors, which are quick, effective, 
and easy to use. (9) Miners will be use side deflectors to eliminate 
the possibility of incidental contact with the air nozzles during use 
of the clothes cleaning booth. (10) Spraying Systems Company Nozzle No. 
AA727-23 contains a recessed design to provide air escape should the 
nozzle be accidentally placed against a surface. (11) An electrically 
actuated valve will be inter-locked into the bag house dust collector 
to prevent use of the clothes cleaning booth if the dust collection 
system is not functioning or inoperable. (12) The clothes cleaning 
booth will be fitted with a stand-alone dust collection system. (13) 
Airflow through the clothes cleaning booth will be sufficient to 
maintain negative pressure during its use in order to prevent 
contamination of the environment outside of the booth. (14) The air 
receiver tank supplying air to the manifold system will be of 
sufficient volume to permit not less than 20 seconds of continuous 
cleaning time. (15) Airflow through the booth will be in the downward 
direction, thereby moving contaminants away from the miner's breathing 
zone. (16) Miners entering the clothes cleaning booth will perform 
regular user checks examining the valves and nozzle for damage of 
malfunction and ensure that the door is fully closed before opening the 
air valve. (17) Periodic maintenance checks will be performed in 
accordance with the NIOSH recommendation contained within the ``Clothes 
Cleaning Process Instruction Manual.'' No significant safety or health 
concerns have been identified because the eyes are protected by full 
seal goggles, the skin is protected by work clothes, hearing is 
protected by plugs or muffs, and the lungs are protected by a 
respirator, and air is limited to 30 pounds per square inch, which is 
the Occupational Safety and Health Administration (OSHA) limit for 
cleaning purposes. The petitioner asserts that the cleaning process 
will provide a more effective clothes cleaning method and a direct 
reduction of a miners' exposure to respirable crystalline silica dust, 
thus reducing their health risks while providing no less a degree of 
safety than that provided by the standard.
