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. The petition may be granted 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-2012-004-C.
    Petitioner: Little Buck Coal Company, 33 Pine Lane, Pine Grove, 
Pennsylvania 17963.
    Mine: Little Buck Slope, MSHA I.D. No. 36-09958, 33 Pine Lane, Pine 
Grove, Pennsylvania 17963, located in Schuylkill County, Pennsylvania.
    Regulation Affected: 30 CFR 75.1200(d) & (i) Mine map).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the use of cross-sections in lieu of 
contour lines on mine maps through the intake slope, at locations of 
rock tunnel connections between veins, and at 1,000 feet intervals of 
advance from the intake slope. In addition, the petitioner proposes to 
limit the required mapping of mine workings above and below to those 
present within 100 feet of the vein(s) being mined unless the veins are 
interconnected to other veins beyond the 100 feet limit through rock 
tunnels. The petitioner states that:
    (1) Due to the steep pitch encountered in mining anthracite coal 
veins, contours provide no useful information and their presence would 
make portions of the map illegible.
    (2) The use of cross-sections in lieu of contour lines has been 
practiced since the late 1800's and provides critical information about 
spacing between veins and proximity to other mine workings, which 
fluctuate considerably.
    (3) The vast majority of current underground anthracite mining 
involves either second mining of remnant pillars from previous mining 
or the mining of veins of lower quality in proximity to inaccessible 
and frequently flooded abandoned mine workings that may or may not be 
mapped.
    (4) All mapping for mines above and below is researched by the 
petitioner's contract engineer for the presence of interconnecting rock 
tunnels between veins in relation to the mine, and a hazard analysis is 
done when mapping indicates the presence of known or potentially 
flooded workings.
    (5) When no rock tunnel connections are found, mine workings that 
exist beyond 100 feet from our mine, are recognized as presenting no 
hazard to the mine due to the pitch of the vein and rock separation.
    (6) Additionally, the mine workings above and below are usually 
inactive and abandoned and, therefore, are not usually subject to 
changes during the life of the mine.
    (7) Where evidence indicates prior mining was conducted on a vein 
above or below and research exhausts the availability of mine mapping, 
the vein will be considered mined and flooded and appropriate 
precautions will be taken through Sec.  75.388, which addresses 
drilling boreholes in advance of mining, where possible.
    (8) Where potential hazards exist and in-mine drilling capabilities 
limit penetration, surface boreholes may be used to intercept the 
workings and the results analyzed prior to beginning mining in the 
affected area.
    The petitioner asserts that the proposed alternative method will 
provide no less than the same measure of protection afforded the miners 
under the existing standard.
    Docket Number: M-2012-005-C.
    Petitioner: Little Buck Coal Company, 33 Pine Lane, Pine Grove, 
Pennsylvania 17963.
    Mine: Little Buck Slope, MSHA I.D. No. 36-09958, 33 Pine Lane, Pine 
Grove, Pennsylvania 17963, located in Schuylkill County, Pennsylvania.
    Regulation Affected: 30 CFR 75.1202 and 75.1202-1(a) (Temporary 
notations, revisions and requirements).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the interval of survey to be established on 
an annual basis from the initial survey in lieu of every 6 months as 
required. The petitioner proposes to continue to update the mine map by 
hand notations on a daily basis and conduct subsequent surveys prior to 
commencing retreat mining, and whenever either a drilling program under 
Sec.  75.388 or plan for mining into inaccessible areas under Sec.  
75.389 is required. The petitioner states that:
    (1) The low production and slow rate of advance in anthracite 
mining make surveying on 6-month intervals impractical. In most cases 
annual development is frequently limited to less than 500 feet of 
gangway advance with associated up-pitch development.
    (2) The vast majority of small anthracite mines are non-mechanized 
and use 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.
    (4) The available engineering/surveyor resources are limited in the 
anthracite coal fields and surveying on an annual basis is difficult to 
achieve with four individual contractors currently available.
    The petitioner asserts that the proposed alternative method will 
provide no less than the same measure of protection afforded the miners 
under the existing standard.
    Docket Number: M-2012-006-C.
    Petitioner: Little Buck Coal Company, 33 Pine Lane, Pine Grove, 
Pennsylvania 17963.
    Mine: Little Buck Slope, MSHA I.D. No. 36-09958, 33 Pine Lane, Pine 
Grove, Pennsylvania 17963, located in Schuylkill County, Pennsylvania.
    Regulation Affected: 30 CFR 75.1400 (Hoisting equipment; general).
    Modification Request: The petitioner requests a modification of the 
existing standard for cages, platforms, or other devices used to 
transport persons in shafts or slopes in underground coal mines. The 
petitioner seeks to permit the use of a slope conveyance (gunboat) to 
transport persons without installing safety catches or other no less 
effective devices but instead use an increased rope strength/safety 
factor and secondary safety rope connection in place of such devices. 
The petitioner states that:
    (1) The haulage slope of this anthracite mine is typical of those 
in the anthracite region, with a relatively high angle and frequently 
changing pitches.
    (2) A functional safety catch capable of working in slopes with 
knuckles and curves is not commercially available. A makeshift device 
would be activated on or by knuckles or curves when no emergency 
exists. Activation of a safety catch can or will damage the haulage 
system and subject persons being transported to hazards from dislodged 
timbering, roof material, or guide rails, and to being battered about 
within the conveyance.
    (3) A safer alternative is to provide secondary safety connections 
securely fastened around the gunboat and to the hoisting rope above the 
main termination and use a hoisting rope

having a safety factor greater than that recommended in the American 
Standards Specifications for the Use of Wire Rope in Mines or at least 
three times greater than the strength required under section Sec.  
75.1431(a).
    The petitioner asserts that the proposed alternative method will 
provide no less than the same measure of protection afforded the miners 
under the existing standard.
    Docket Number: M-2012-007-C.
    Petitioner: RoxCoal, Inc., 1576 Stoystown Road, Friedens, 
Pennsylvania 15541.
    Mines: Agustus Mine, MSHA I.D. No. 36-08636; Barbara <greek-i>2 
Mine, MSHA I.D. No. 36-08508; Horning Mine, MSHA I.D. No. 36-09666; 
Kimberly Run Mine, MSHA I.D. No. 36-09549; Quecreek <greek-i>1 Mine, 
MSHA I.D. No. 36-08746; Roytown Deep Mine, MSHA I.D. No. 36-09260; 
Sarah Mine, MSHA I.D. No. 36-08571; all located in Somerset County, 
Pennsylvania.
    Regulation Affected: 30 CFR 75.503 (Permissible electric face 
equipment; maintenance) and 30 CFR 18.35(a)(2) (Portable (trailing) 
cables and cords).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit an alternative method of compliance with 
the 10 American Wire Gauge (AWG) Cable. The petitioner proposes to use 
MSHA approved five (5) conductor 10 AWG cable (SO cable) with a 
diameter of .77 with a tolerance of +/-0.03. The petitioner states 
that:
    (1) The cable will hang on insulated hangers for the entire length 
at all times.
    (2) Within 60 days after the Proposed Decision and Order becomes 
final, the petitioner will submit proposed revisions for its approved 
30 CFR part 48 training plan to the District Manager. In addition to 
the requirement specified in item 1, these 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.
