Chapter II <br /> Water for the Coal Basin central complex facilities and Adit/Rock Tunnel lamphouse <br /> is obtained from groundwater wells which have been permitted by the Department <br /> of Natural Resources - Water Resource Division (Chapter I, Section G). <br /> Commercially bottled water is provided to drink. <br /> J. Communication. <br /> Telephone communication to Coal Basin is provided by Mountain Bell. The main <br /> trunk line extends from Redstone to the office complex area, roughly parallel to the <br /> power line and the road. The telephone line is buried. <br /> From the office complex area, underground telephone lines extend to the portal <br /> areas of Main Entries #1, #2, #3, #4 and #5, and to the Adit/Rock Tunnel and <br /> lamphouse. <br /> Mid-Continent operates an independent radio system for surface communications. <br /> Within the mine, a network of telephones provide communication to other parts of <br /> the mine, and outside. <br /> k. Explosives Storage. <br /> Explosives are stored in storage facilities, constructed of cinderblock and concrete, <br /> which are weather resistant, bullet-proof and fire-proof. See Exhibits II-B-4 a-d. <br /> The explosive-storage facilities comply with specifications of the U.S. Department of <br /> Treasury, with MSHA regulations for explosives storage, with Title 27, Part 181 of <br /> the Code of Federal Regulations, covering storage of explosive material. <br /> Explosives are transported to the storage facilities in accordance with the <br /> requirements of Title 49, Chapter III, Parts 390-397 of the U.S. Department of <br /> Transportation, Federal Highway Administration, Bureau of Motor Carrier Safety, <br /> and of MSHA. <br /> 4. Ponds, Impoundments and Diversions. <br /> a. General - Hydrologic Control Plan. <br /> A complex system of mine drainage facilities, collection or diversion ditches, and <br /> sediment ponds have been designed and constructed in the Coal Basin to protect <br /> water quality. All have been designed to meet federal/state engineering <br /> specifications. (See Chapter 11, Appendix II-B-7, Hydrologic Control Plan; Chapter <br /> III-E Hydrology Description and Chapter IV-C Protection of the Hydrologic Balance). <br /> The hydrologic control system for the Coal Basin permit area is designed to divert <br /> surface water around disturbed areas where possible, collect all water drained from <br /> mines and flowing out of disturbed areas, hold it in sedimentation ponds until its <br /> 24 <br />
