iii iiiiiiiiiiiu iii STATE, OF COLORADO Roy Romer, Govei DEPARTMENT OF NATURAL RESOURCES MINED LAND RECLAMATION DIVISION FRED R. BANTA, Director April 6, 1989 Mr. Jerry Koblitz Permittee Liason Wyoming Fuel Company 12055 West 2nd Place Lakewood, CO 80215 Re: Hydrology, Canadian Strip Mine; C-81-026 Dear Mr. Koblitz: Following a perusal of the permit application, I found some information about Pond 3, which I confirmed during a telephone conversation with Glenn Murdoch. The original Figure 2 of the permit application, dated March 31, 1981, showed Pond 3 at its current locations. It apparently was constructed after lengthy discussion about erosion from the upslope haul road. During the 1986-1987 reclamation there was discussion about removal of the impoundment, but it was felt that removal was inappropriate until vegetation success could be ensured on the road and contributing drainage area. Wyoming Fuels represented to the Colorado Department of Health (DOH) that Pond 3 was removed when the NPDES permit was reissued on August 26, 1987. As this is not the case, I would like Wyoming Fuels to notify CDOH of Pond 3's existence and apply for an appropriate amendment. Alternatively, Wyoming Fuels could apply for pond removal (per Rule 4.05.2(2)). Furthermore, it would be prudent to prepare a quarterly self-inspection of ponds document and to find the certification for Pond 3 prior to the next complete inspection. I have found a cover letter dated February 6, 1981 from John Althouse to Bob Liddle for the certification of Pond 3 in Appendix Q of the permit appli- cation. Please check your files for the actual certification. I have enclosed a copy of our records checklist for your use. You may decide it is appropriate to consolidate copies of all of the small records into one notebook to expedite the records review during complete inspections. 215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 TeI.
