-15- <br />exploration holes on the permit area above the proposed Bear No. 3 workings, <br />no water was encountered. With subsequent mining at the Bear No. 3 the old <br />Edwards workings were found to be dry. <br />The analyses of the C Seam coal requested by the Division is provided on page <br />2.04-21 of the Bear No. 3 application. <br />The addition of Federal Coal Lease No. C-0117192 will not change the geologic <br />description. <br />V. Hydrologic Balance: Surface Water - Rul <br />an <br />For a description of the surface water hydrology of the mine area and a <br />discussion of the impacts of mining on surface water, refer to the Surface <br />Water Hydrology portion of Section IX, Probable Hydrologic Consequences and <br />Cumulative Impact Assessment of this document. <br />The surface water hydrology information, sediment control and protection of <br />the hydrologic balance sections of the application have been reviewed•by the <br />Division. The surface water information sections can be found on pages 47-1a <br />through 49 of the Bear No. 1 and No. 2 section of the application, and pages <br />2.04-31 through 2.04-33 of the Bear No. 3 section. Drainage and sediment <br />control text, plans and calculations are presented on pages 62 through 65 of <br />the first part of the application, and 2.05-22 through 2.05-23 and in Exhibit <br />11 of the second part of the application. <br />Drainage control at the No. 3 Mine includes a sediment pond and a system of <br />collection ditches and culverts. <br />Due to the location of the Bear No. 3 surface facilities on the flood plain of <br />the North Fork, there was a potential for portions of the facilities to be <br />inundated by flooding of the North Fork. The applicant has submitted a map <br />indicating the water levels that would be reached at various flood stages, and <br />verifying that portions of the site, notably the sediment pond and coal <br />stockpile, would be affected by waters of the 10-year and 50-year recurrence <br />flood. The major portion of the facilities area could be inundated by a <br />100-year recurrence flood. The applicant, to remedy the problem with <br />flooding, has constructed a berm along the perimeter of the disturbed area of <br />sufficient size to contain the waters of the 100-year recurrence flow. Also, <br />the banks of the berm have been rip-rapped to stabilize it from erosion. <br />Registered Professional Engineer Certification of the berm has been received, <br />and seeding and planting is planned for the Fall of 1985. Currently this <br />portion of the facility is in compliance. <br />Following the Division of Highway's river channel relocation project, portions <br />of the disturbed area, including the sediment pond, topsoil stockpile, and <br />coal stockpile fell within 100 feet of the streambank. These areas had been <br />previously disturbed by past mining-related activity. <br />The applicant had requested, and the Division authorized, a variance from the <br />100 foot stream buffer zone requirement. <br />
