SUNNYSIDE GOLD CORPORATION AN ECHO EAY COMPANY Mr. Fred Banta, Director Mined Land Reclamation Division Dear Mr. Banta: P.O. Box 177 . Silverton, CO 81433 RECEIVED Phone (303) 387 -5533 . Telecopy (303) 387 -5310 SAY 21988 MINED LAND RECLAMATION DIVISION April 29, 1988 Colorado Department of Natural Resources 1313 Sherman Street Denver, Colorado 80203 -2273 III IIIIIIIIIIIIIIII 999 v‘ i77 77-37' Re: Disposal of Settling Pond Sediments at Sunnyside Gold Mine TerLy Tunnel Facility Pursuant to our conversations of April 28, 1988, Sunnyside Gold Corporation (SGC) requests an extension of the May 2, 1988 deadline for submission of a response to the Division concerning transport of Terry Tunnel settling pond sediments from the Terry Tunnel mine bench to Tailings Pond No. 3. The deadline of May 2 was requested by Ms. Camille Farrell in a technical review letter on the SGC Permit Amendment No. 3 proposal dated April 6, 1988. This short extension is requested in order to assure a complete airing of SGC and Division positions and concerns over the character of this material, and the requirements contained in the approved consolidated permit (Amendment No. 2 to M -77 -378) relative to its handling. It is the opinion of SGC, based on site evaluation and laboratory analysis, that these materials may be disposed of on -site and reclaimed, rather than transported to Tailings Pond No. 3. SGC has requested via Permit Amendment No. 3 that vegetative studies be conducted on these materials in order to assess their true reclaimability. The current Division position is tied to the Amendment No. 2 provision for disposal of "sludge" on Tailings Pond No. 3 only. SGC does not agree that these materials meet the definition of "sludge" as implied in the permit, and that in -place reclamation trials are appropriate. These trials have been proposed in the approved Amendment No. 3 and, with Division approval, the studies can be initiated during the 1988 field season.
