## 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 § 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 § 75.388 or plan for mining into inaccessible areas under § 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                           ( print page 14440)                        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 § 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 #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 #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.
