v UJyoming fuel Com~en~ 445 Union Boulevard • Suite 310 • Lakewood, Colorado 80228 • Telephone (303)989-5037 December 8, 1981 Mr. Tom Guobis Brooks Towers 1020 15th Street Denver, Colorado 80202 Dear Mr. Guobis: Pursuant to our meetings of November 25, 1981 and December 7, 1981, and our telephone conversation of November 30, 1981, [4yoming Fuel Company is supplying additional information for the Canadian Strip Mine. The information being supplied is in regard to reclamation and reference area monitoring. It is our under- standing this information is being supplied to avoid unnecessary stipulations to our mining permit. 1. Range conditions on both reference areas will be monitored every five years from the time of permit approcal by the U.S.D.A. Soil Conservation Service in order to show that these areas are in at least fair range condition. This evaluation shall be sub- mitted to the regulatory authroity (RA) by the end of each year in which the survey is conducted. If either or both of the ref- erence areas are determined to be in less than fair range condition at any of these survey times, Wyoming Fuel Company will design in consultation with the regulatory authority, the use appropriate mitigative measures to attempt to restore these areas to fair range condition. Wyoming Fuel Company will subjectively review the ref- erence areas during the periods between these five year evaluations. This interim evaluation will be an effort to insure reference areas are maintained in fair condition. In the event the range condition increases to above fair condition during any of these above times frames and particularly during bond release Wyoming Fuel Company will rely solely on baseline data to evaluate revegetation success. It may also be necessary to adjust vegetative success data on reference areas as a result of weather conditions during the bond release period. This is to insure data taken from the reference area is comparable to the conditions when premining vegetation data was collected. An appropriate revegetation success methodology will be developed in consultation with Wyoming Fuel Company and the RA, in the event the condition of the reference area(s) increases beyond fair.
