III IIIIIIIIIIIII III sss E~~A S Coal Company Seneca Coal Company December 5, 1996 RF_CEIVED Ms. Erica Crosby DEC 09 1996 Division of Minerals and Geology 1313 Sherman Street, Room 215 Denver, CO 80203-2273 ~~~~~<.~or~„,~•~~~,„~~~~.~Geoiogy R8: Seneca II-W Mine Permit C-82-057, NOV C-95-023 Dear Ms. Crosby: This correspondence is a request for an extension of time for the abatement of NOV C-95-023 to the Seneca II-w Mine Permit C-82-057. The current abatement deadline for this NOV is Monday, December 9th. Seneca has initiated the field implementation of the abatement plans approved in Technical Revision No. 25. We have removed the topsoil over the area which needs to be regraded. Seneca still needs to get the final slope back to a 3:1, replace the topsoil and revegetate the redisturbed acreage. Also some additional drainage work needs to be redone. Because of the weather and ground conditions over the last two months this work has not been able to progress as anticipated. The ground has been wet and very muddy and detrimental work has occurred each time we have had a bulldozer start cutting this slope down. Mobile equipment operator safety on this slope is also a concern at the present time. Unfortunately, the window for topsoil replacement and revegetation activities has passed us. To complete the entire abatement plans will take us into the spring of 1997 when all snowmelt has taken place. I am asking for a 90-day extension of the current deadline to March 9th. Should you or any other members of the Division have any questions regarding this information, please do not hesitate to contact me. Sincerely, ~w~Q,9d . Michael G. Altavilla, P.E.
