In the matter of Petition for Modification Blue Diamond Coal Company
I.D. No. 15-17478 Docket No. M-2007-011-C PROPOSED DECISION AND ORDER
On January 04, 2007, a petition was filed seeking a modification of the application of 30
§ 75.364(b)(2) to Petitioner's #75 Mine, located in Perry County, Kentucky. The Petitioner alleges that application of this standard will result in a diminution of safety to the miners. Petitioner also alleges that the alternative method proposed in the petition will at all times guarantee no less than the same measure of protection afforded by the standard without unnecessarily exposing persons to hazardous conditions.
MSHA personnel conducted an investigation of the petition and filed a report of their findings and recommendations with the Administrator for Coal Mine Safety and Health. After a careful review of the entire record, including the petition and MSHA's investigative report and recommendation, this Proposed Decision and Order is issued.
Finding of Fact and Conclusion of Law
The petitioned standard, 30 C.F.R. § 75.364(b)(2), requires,
Hazardous conditions. At least every 7 days, an examination for hazardous conditions at the following locations shall be made by a certified person designated by the operator:
(2) In at least one entry of each return air course, in its entirety, so that the entire air course is traveled.
Application of 30 C.F.R. § 75.364(b)(2) to the subject mine will result in a diminution of safety to the miners and the special terms and conditions set out below will at all times provide a safe work environment to the miners.
The petitioner alleges that a roof falls and water accumulations have blocked travel in the Power Line Mains air course from crosscut 17 to crosscut 26 making the area unsafe for mine examiners to travel. In addition, the proposed alternative method of having a certified person take weekly air quantity and quality measurements at monitoring stations #A1 through #A8, as shown on the attached map (Exhibit 1), at both sides of the unsafe roof area will provide the same measure of protection as the standard.
MSHA’s investigation confirmed that numerous roof falls and water have blocked travel in the Second East Return aircourse for approximately 12 crosscuts, the area has become unsafe for mine examiners to travel, and the area has been rendered essentially impractical to rehabilitate. In addition, the investigation confirmed that the eight monitoring points, as shown on the attached map, were accessible. MSHA’s investigation revealed that the high-volume airflow in all monitored entries would prevent accumulations of methane; consequently, there is no need for more frequent (daily) examinations.
Wherefore, pursuant to the authority delegated by the Secretary of Labor to the Administrator for Coal Mine Safety and Health, and pursuant to Section 101(c) of the Federal Mine Safety and Health Act of 1977, 30 U.S.C. § 811(c), it is ordered that Blue Diamond Coal Company’s Petition for Modification of the application of 30 C.F.R.
§ 75.364(b)(2) in the #75 Mine is hereby:
GRANTED, for the examination of approximately twelve crosscuts of unsafe-to- travel return air course in the Power Line Mains air course between the monitoring stations as indicated on the attached map, conditioned upon compliance with the following terms and conditions:
Eight (8) monitoring stations, identified as EP-A1 through EP-A8, shall allow effective evaluation of airflow through the air course between the unsafe-to- travel areas used to ventilate the Power Line Mains. The monitoring stations shall be established as follows:
Monitoring stations EP-A1, EP-A2, EP-A3, EP-A4, and EP-A5 shall be established as indicated on the attached map and used to monitor the air entering the Power Line Mains between crosscuts 15 and 16.
Monitoring stations EP-A6, EP-A7, and EP-A8 shall be established as indicated on the attached map and used to monitor the air exiting the Power Line Mains between crosscuts 27 and 28.
Signs showing the safe travel route to each monitoring station shall be conspicuously posted in an adjacent travel entry. The monitoring stations and routes of travel to the monitoring stations shall be kept free of water accumulations.
A certified person shall conduct weekly evaluations at each of the monitoring stations. The evaluations shall include the quantity and quality of air entering or exiting the monitoring station. The evaluation shall also include a determination of any airflow from adjacent entries, defined and measured as stated in Paragraph 8 below. These air measurements shall be made using MSHA approved and calibrated hand-held multi-gas detectors to check the methane and oxygen gas concentrations and appropriate, calibrated anemometers to check airflow volume.
A diagram showing the normal direction of the airflow shall be posted at the monitoring stations. The diagram shall be maintained in legible condition and any change in airflow direction shall be reported to the mine foreman for immediate investigation.
The date, initials of the examiner, time, and the measured quantity and quality of air shall be recorded in a book or on a date board that shall be provided at the monitoring stations. Such results, including the condition of the accessible permanent ventilation controls creating the aircourse, shall also be recorded in a book kept on the surface and made accessible to all interested parties.
All monitoring station and approaches to monitoring station shall, at all times, be maintained in a safe condition. The roof shall be adequately supported by roof bolts or other suitable means to prevent deterioration of the roof in the vicinity of the stations.
Methane gas or other harmful, noxious, or poisonous gases shall not be permitted to accumulate in excess of legal limits for return air. An increase of 0.5 percent methane above the last previous methane reading or a 10 percent change in airflow quantity shall cause an immediate investigation of the affected area. The results of the investigation shall be immediately reported to the mine foreman.
The initial airflow from adjacent aircourses shall be determined during the first evaluation following implementation of this modification. Airflow from adjacent aircourses is defined as the difference between the air quantity entering and exiting the petitioned area, as measured at the monitoring stations. A 10 percent change from the initial airflows in the aircourse shall cause immediate examination and evaluation of the cause. Appropriate corrective action must then be taken. Following corrective action, a new “initial airflow” shall be determined and serve as the basis for subsequent evaluations.
The monitoring station location(s) shall be shown on the annually submitted mine ventilation map. The stations shall not be moved to another location without prior approval by the District Manager as a part of the Ventilation Plan for the mine.
Prior to implementing this modification, all mine personnel shall be instructed that, except along designated routes, no travel into the petitioned area shall be permitted and all other approaches shall be fenced off or barricaded with "DO NOT ENTER" warning signs. Entry in the area shall be permitted only to conduct investigations and correct problems with airflow detected through the monitoring process and all such work will be done under the supervision of an authorized person. All persons who work in the area shall be instructed in the emergency evacuation procedures and all provisions of 30 C.F.R. §§ 75.1502, 75.1504, and 75.1505.
Within 60 days after this Proposed Decision and Order becomes final, the Petitioner shall submit proposed revisions for its approved 30 C.F.R. Part 48 training plan to the Coal Mine Safety and Health District Manager. These proposed revisions shall include initial and refresher training regarding compliance with this Proposed Decision and Order.
Any party to this action desiring a hearing on this matter must file in accordance with 30 C.F.R. § 44.14, within 30 days. The request for hearing must be filed with the Administrator for Coal Mine Safety and Health, 1100 Wilson Boulevard, Arlington, Virginia 22209-3939. If a hearing is requested, the request shall contain a concise summary of position on the issues of fact or law desired to be raised by the party requesting the hearing, including specific objections to the proposed decision. A party other than Petitioner who has requested a hearing may also comment upon all issues of fact or law presented in the petition, and any party to this action requesting a hearing may indicate a desired hearing site. If no request for a hearing is filed within 30 days after service thereof, the Decision and Order will become final and must be posted by the operator on the mine bulletin board at the mine.
