26 20 . FORMAL PUBLIC HEARING PITTSBURG & MIDWAY COAL MINING COMPANY File No.C-80-001 Edna Strip Mine. Staff distributed a package of information, including copies of the NOV package, an inspection report, maps, pictures and the operator June 30, 1993 request for formal review. This matter related to the operator' s request that the Board vacate NOV C-93-026. The Division inspected the site during the March 30 through April 1, 1993 inspection period. Staff referenced Rules 4.05 .5 (1) (c) and 4.05.5 (2) (c) and said this NOV was written for failure to design, construct and maintain sediment control measures to minimize erosion, as necessary, to provide protection for topsoil and vegetation and for failure to retain sediment within disturbed areas. The intent of the Regulation is to minimize offsite impacts using the best technology currently available to provide protection for topsoil and vegetation. The NOV applied to the Grizzly Pad facilities area, the east side of the upper facilities area and the outlet of Culvert E- 12 . An assessment conference was held and that the conveyor belt was modified out of the NOV during that meeting. Staff referenced the package of information and discussed the Grizzly Pad which measures about 300 feet by 400 feet of gravel and dirt surfacing. The area contains coal screens and a small coal stockpile, and is surrounded on three sides by reclaimed land. Staff said that drainage on the Grizzly Pad is usually controlled by a system of a berm and a ditch that route drainage back to the haul road, the entrance of the Pad and to the west ridge pond. Staff discussed the location of the areas included in the NOV. The upper facilities area measures about eight acres and is a dirt and gravel yard which houses the shop, offices, warehouse, maintenance shops and a coal stockpile. A at the time of the inspection, snow and coal material from the facilities yard had been pushed over the berm located on the east side of the facilities yard. The operator' s activity caused the material to be deposited on undisturbed areas where topsoil and vegetation had not been removed. Staff discussed the violation related to Culvert E-12 . At the time of the inspection, the culvert was plugged with coal fines and mud. Staff said that a slurry of mud and coal fines had flowed through the culvert and out onto reclaimed areas and that topsoil and vegetation was contaminated by the mud and the coal . Staff discussed the reclaimed areas on which the bond had been released and said the areas are now considered undisturbed.
