SUPPLEMENTAL 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 determines that 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 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 modifications.
II. Petitions for Modification
Docket Number: M2006067C.
Petitioner: West Ridge Resources, Inc., P.O. Box 1077, Price, Utah 84501.
Mine: West Ridge Mine, (MSHA I.D. No. 4202233), located in Carbon County, Utah.
Regulation Affected: 30 CFR 75.350 (Air courses and belt haulage entries).
Modification Request: The petitioner has filed a petition for modification to request that Section V. (B)(5) of the Proposed Decision and Order (PDO) for previously granted petition, docket number M1999 026C, be amended to insert the following subparagraphs:
1. In addition to the requirements of (B)(5), and subject to the terms set forth in paragraph 2 of this subpart, dieselpowered equipment classified as ``heavyduty'' under 30 CFR 75.1908(a) must include a means, maintained in operating condition, to maintain the surface temperature of the exhaust system of diesel equipment below 302[deg] Fahrenheit.
2. In the absence of a safe and reasonable means to comply with the
requirement set forth in Paragraph 1 of this subpart, the following requirements shall apply.
(i) All hydraulic hoses, fuel lines, or other devices used to
convey combustible fluids must be separated from the hot engine
exhaustsystem surfaces by piping rerouting, barriers or other means
acceptable to MSHA. Such hoses, lines, or other devices used to convey
combustible fluids that by design cannot be separated as required may
be insulated using Kevlar or equivalent insulation product.
(ii) Engine exhaust system must be designed to minimize contact
with combustible materials. Where safe and reasonable, exhaust pipes
outside of the engine compartment must be of doublewall construction.
Joints in the exhaust systems must consist of flanged connections utilizing gaskets and/or solid welded construction.
(iii) In addition to the requirements of 30 CFR 75.1909, 4braid
hoses must be used where a hose failure could result in combustible
fluids contacting parts of the exhaust systems. Hoses should be covered
with a Kevlar covering such as Protect, NHS125, MSHA IC171/1, or an equivalent covering acceptable to MSHA.
(iv) Diesel equipment must be equipped with both an automatic and
manual firesuppression system meeting the requirements of 30 CFR
75.1911 and capable of being activated from inside and outside the
machine operator's cab. The manual activator located outside the cab
must be on the side of the machine opposite the operator's cab. The
firesuppression system must be installed by a reputable fire
suppression vendor with an enhanced firehazard analysis designed to
address a higher level of fire protection for machines that are
operated in twoentry mining systems. Each dieselpowered machine must
be equipped with two handheld fire extinguishers. Diagrams specific to
each diesel family must be developed and retained by the mine operator to
[[Page 70549]]
document how each enhanced firesuppression system must be maintained.
A record of each enhanced firesuppression system diagram shall be
maintained on the surface and be made available to all interested persons.
(v) Diesel equipment with diesel particulate matter disposal
filters must be fitted with high exhaust gas temperature shutdown
sensors to prevent the operation of the machine if the exhaust gas
exceeds 650[deg] Fahrenheit at the filter inlet. The shutdown sensors
must be located as near the filter housing (filter inlet) as practical as determined by MSHA.
(vi) The visual inspection of diesel equipment required by 30 CFR
75.1914 must include an examination of the protective devices installed
to control exhaustsystem surface temperatures, hoses, fuel lines, and
all other materials designed to prevent combustible fluids from contacting hot engine exhaustsystem surfaces.
(vii) All underground miners working in the twoentry areas of the
mine must be trained in the terms and conditions listed in this
modification and the fire hazards involved with equipment working in these areas.
The petitioner asserts that this amendment to the petition for
modification is filed to prevent a diminution of safety and the
proposed alternative method would provide at least the same measure of protection as the existing standard.
Docket Number: M2006068C.
Petitioner: Consol Pennsylvania Coal Company, 1800 Washington Road, Pittsburgh, Pennsylvania 15241.
Mine: Bailey Mine1 South, (MSHA I.D. No. 3607236), located in Greene County, Pennsylvania.
Regulation Affected: 30 CFR 75.364(b)(2) (Weekly examination).
Modification Request: Due to deteriorating roof conditions, the petitioner proposes to establish evaluation check points 1 and 2 to evaluate and confirm the proper ventilation between 1 South 4 Wall and 29 Wall, and check points 3 and 4 to evaluate the intake air course between 1 South and 31 Wall, and 90 Wall. The petitioner states that intake air enters the mine at the two (2) 1 South Shafts in the area between points 2 and 3. The petitioner further states that the air quality and quantity at each check point will be measured weekly by a certified person who will enter the date, time and initials to indicate that an examination was conducted at each location, record the results of the examinations in a book provided for such purposes, and certify by signature that the examination was conducted. The record book will be kept on the surface for a period of six months and made available for inspection by interested persons. The petitioner asserts that the proposed alternative method would provide at least the same measure of protection as the existing standard and that use of the check points to measure air and gas will provide an accurate picture of the conditions in the air course without unduly exposing persons to safety hazards.
Docket Number: M2006069C.
Petitioner: Consol Pennslyvania Coal Company, 1800 Washington Road, Pittsburgh, Pennsylvania 15241.
Mine: Bailey Mine81 Longwall, (MSHA I.D. No. 3607230), located in Greene County, Pennsylvania.
Regulation Affected: 30 CFR 75.364(b)(2).
Modification Request: Due to deteriorating roof conditions in the
intake air course located in the 81 longwall set up entries, the
petitioner proposes to establish evaluation check points 1 and 2 to
evaluate and confirm the adequate ventilation over the fall. The
petitioner states that the air quality and quantity at each check point
will be measured weekly by a certified person who will enter the date,
time and initials to indicate that an examination was conducted at each
location. The petitioner further states that results of the
examinations will be recorded in a book that will be certified by
signature that the examination was conducted, and kept on the surface
available for inspection by interested persons. The petitioner asserts
that the proposed alternative method would provide at least the same
measure of protection as the existing standard, and use of the check
points to measure air and gas will provide an accurate picture of the
conditions in the air course without exposing persons to safety hazards.
Docket Number: M2006070C.
Petitioner: Excel Coal Company, RD 2 Box 665, Shamokin, Pennsylvania 17872.
Mine: 3 S. Slope Mine, (MSHA I.D. No. 3609309), located in Northumberland County, Pennsylvania.
Regulation Affected: 30 CFR 75.335 (Construction of seals).
Modification Request: The petitioner proposes to: (1) Construct seals from wooden materials of moderate size and weight; (2) design the seals to withstand a static horizontal pressure in the range of 10 psi; and (3) install a sampling tube in the monkey (higher elevation) seal. The petitioner states that the pitch of anthracite veins and concrete blocks are difficult to use and will expose miners to safety hazards during transport. The petitioner cites lowlevel explosibility of anthracite coal dust and minimal potential for either an accumulation of methane in previously mined pitching veins or an ignition source in the gob area, as justification for the proposed 10 psi design. The petitioner asserts that the proposed alternative method would provide at least the same measure of protection as the existing standard.
Docket Number: M2006071C.
Petitioner: Excel Coal Company, RD 2 Box 665, Shamokin, Pennsylvania 17872.
Mine: 3 S. Slope Mine, (MSHA I.D. No. 3609309), located in Northumberland County, Pennsylvania.
Regulation Affected: 30 CFR 75.1202 and 75.12021(a) (Temporary notations, revisions, and supplements).
Modification Request: The petitioner requests a modification of the
existing standard to permit the required interval of survey to be
established annually from the initial survey in lieu every 6 months.
The petitioner proposes to update the mine map by hand notations on a
daily basis, conduct subsequent surveys prior to commencing retreat
mining, and when either a drilling program under 30 CFR 75.388 or plan
for mining into accessible areas under 30 CFR 75.389 is required. The
petitioner states that: (1) Low production and slow rate of advance in
anthracite mining make surveying on 6 month intervals impractical and,
in most cases, annual development is frequently limited to less than
500 feet of gangway advance with associated uppitch development; (2)
The majority of small anthracite mines are using nonmechanized, hand
loading mining methods; (3) Development above the active gangway is
designed to mine into the level above at designated intervals thereby
maintaining sufficient control between both surveyed gangways; and (4)
The available engineering/surveyor resources are very limited in
anthracite coal fields which makes surveying on an annual basis
difficult to achieve with 4 individual contractors currently available.
The petitioner asserts that the proposed alternative method would
provide at least the same measure of protection as the existing standard.
Docket Number: M2006072C.
Petitioner: Excel Coal Company, RD 2 Box 665, Shamokin, Pennsylvania 17872.
Mine: 3 S. Slope Mine (MSHA I.D. No. 3609309) located in Northumberland County, Pennsylvania.
Regulation Affected: 30 CFR 49.6(a)(1) & (5) ) (Mine Rescue teams).
Modification Request: The petitioner requests a modification of the existing
[[Page 70550]]
standard to permit the reduction of twelve selfcontained oxygen
breathing apparatus, to eight selfcontained breathing apparatus and
the reduction of twelve permissible cap lamps and charging rack to
eight permissible cap lamps and charging rack. The petitioner asserts
that this petition request will in no way alter, change, or reduce the
ability, effectiveness, or safety of the underground mine personnel.
Docket Number: M2006073C.
Petitioner: T.J.S. Mining, Inc., 2340 Smith Road, Shelocta, Pennsylvania 15774.
Mines: Rossmoyne No. 1 Mine, (MSHA I.D. No. 3609075), located in Indiana County, Pennsylvania; T.J.S. No. 5 Mine, (MSHA I.D. No. 36 09159), located in Armstrong County, Pennsylvania; and T.J.S. No. 6 Mine, (MSHA I.D. No. 3609464), located in Armstrong County, Pennsylvania.
Regulation Affected: 30 CFR 75.11002(e)(2)) (Quantity and location of firefighting equipment) .
Modification Request: The petitioner proposes to supply two (2)
fire extinguishers or one fire extinguisher of twice the required
capacity at all temporary electrical installations in lieu of using 240
pounds of rock dust. The petitioner asserts that the proposed
alternative method would provide at least the same measure of protection as the existing standard.
Docket Number: M2006074C.
Petitioner: T.J.S. Mining, Inc.,/Penn View Mining, Inc., 2340 Smith Road, Selocta, Pennsylvania.
Mines: Rossmoyne No. 1 Mine, (MSHA I.D. No. 3609075), located in Indiana County, Pennsylvania; Darmac No. 2 Mine, (MSHA I.D. No. 36 08135), located in Armstrong County, Pennsylvania; T.J.S. No. 5 Mine, (MSHA I.D. No. 3609159), located in Armstrong County, Pennsylvania; and Penn View Mine, (MSHA I.D. No. 3608741), located in Indiana County, Pennsylvania.
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 an alternative method for conducting the 31
day test of the fan signal. The petitioner states that to conduct the
31 day test procedure requires stopping and restarting the fan which
can cause failure to the fan's electrical circuit, and further undue
burden if the fan cannot be restarted within the required fifteen (15)
minutes. If the fan is stopped, this would require a special
examination to be conducted which requires crawling approximately 2
miles because some of the mines are thin seam mines (34''36'' height).
The petitioner asserts that the proposed alternative method would
provide at least the same measure of protection as the existing standard.
Docket Number: M2006075C.
Petitioner: San Juan Coal Company, P.O. Box 561, Waterflow, New Mexico 87421.
Mine: San Juan South Mine, (MSHA I.D. No. 2902170), located in San Juan County, New Mexico.
Regulation Affected: 30 CFR 75.1700 (Oil and gas wells).
Modification Request: The petitioner has filed a petition for
modification to request that Section 2 of the Proposed Decision and
Order for its previously granted petition, docket number M2000109C,
be amended. The petitioner's previously granted petition permits mining
through oil and gas wells. The petitioner requests that Section 2 of
the Proposed Decision and Order of its previously granted petition be
changed to further clarify the specific procedures required when
approaching and cutting through the well, and to also bring the
petition more in line with other granted petitions for safety standard
30 CFR 75.1700. The petitioner asserts that this amendment to the
previously granted petition will provide at least the same measure of protection as the existing modification requirements.
Docket Number: M2006010M.
Petitioner: Swenson Granite Company, LLC, 369 North State Street, Concord, New Hampshire 03301.
Mine: Swenson Gray Quarry, (MSHA I.D. No. 2700083), located in Merrimack County, New Hampshire.
Regulation Affected: 30 CFR 56.19009 (Position indicator).
Modification Request: The petitioner proposes to use stateofthe
art Pelligrini and Timberland stiffleg derricks as manhoists into the
dimensional stone quarry, and use the company's hand signaling system
daily to direct the derrick as an alternative to using the Position
Indicator. The petitioner states that Swenson Granites' Gray Quarry is
an open dimensional granite quarry that operates fixed stiffleg
derricks to lift stone and equipment, and that an accurate and reliable
indicator of the skip or cage position will be provided in the shaft.
The petitioner further states that the derricks operate and reach all
areas of the quarry floor and walls and offer full view of the hook and
loads, and the operation relies 100 percent on constant view of the
hook and load, or the operation is stopped and conditions are improved
to 100 percent visibility. The petitioner asserts that the proposed
alternative method would provide at least the same measure of protection as the existing standard.
Docket Number: M2006011M.
Petitioner: Swenson Granite Company, LLC, 369 North State Street, Concord, New Hampshire 03301.
Mine: Swenson Gray Quarry, (MSHA I.D. No. 2700083), located in Merrimack County, New Hampshire.
