~ 1 Mid-Term Review 19 November 27, 1985 The initial Mid-Term review letter for the Deserado Mine indicated that the requirements of this stipulation had been satisfied. However, no specific revegetation success criteria for species diversity could be located on page V-51a of the application. This page must be revised to state, for each affected plant community, the specific species diversity success standard proposed by the Division in a letter to Western Fuels dated April 1, 1982. The standard calls for 2 cool season grasses and one forb to be established, with each species to contribute greater than 3% relative cover. This standard applies to both lowland and upland seed mixes. (Part 2) WITH RESPECT TO THE USE OF REFERENCE AREAS AND RANGE SITE DESCRIPTIONS IN DETERMINATION OF REVEGETATION SUCCESS, THE PROCEDURES OUTLINED IN COMMENT 5 OF THE APRIL 20, 1981 LETTER TO WESTERN FUELS ARE TO BE FOLLOWED. POOR CONDITION REFERENCE AREAS ARE TO BE FENCED. IF A CONDITION CHECK AT THE TIME OF BOND RELEASE INDICATES THAT THE REFERENCE AREA IS STILL IN POOR CONDITION, ALTERNATIVE SUCCESS STANDARDS WILL BE SET BY THE REGULATORY AUTHORITY. CONDITION CHECKS AT THE TIME OF REQUESTED BOND RELEASE ARE TO INCLUDE SHRUB, AS WELL AS HERBACEOUS, PRODUCTION. SECTION D ON PAGE V-51, SECTION E ON PAGE V-51 a, AND SECTION E ON PAGE V-53 SHALL BE REVISED ACCORDINGLY. The Division's initial February 7, 1984 midterm review letter for the Deserado mine indicated that the requirements of this stipulation had been satisfied, however it appears that none of the revised pages have been inserted into the permit application. To properly resolve this stipulation, Western Fuels should provide a statement on the above indicated pages committing to conducting an evaluation of the range condition of each of the reference areas at the time of bond release. The range Condition evaluation will involve measuring both herbaceous and woody plant production. Western Fuels should further commit to developing an alternative set of revegetation success standards in consultation with the Division if the range evaluation results indicate a poor range condition. Stipulation No. 20 WESTERN FUELS MUST BE SUBMIT, FOR THE REGULATORY AUTHORITY APPROVAL, A DETAILED SAMPLING PLAN INCORPORATING THE REQUESTED CHANGES IN PLOT SIZE AND TRANSECT DESIGN. THIS PLAN MUST BE SUBMITTED PRIOR TO THE COMMENCEMENT OF SAMPLING FOR 1981. An approved vegetation sampling program was undertaken during the summer of 1981. Therefore, the requirements of Stipulation No. 20 have been satisfied. Stipulation No. 21 ATRIPLEX CONFERTIFOLIA MUST BE REMOVED FROM THE PROPOSED SEEDMIXES AND REPLACED BY ATRIPLEX CANESCENS. IN ADDITION, COLORADO WILDRYE WILL BE SUBSTITUTED FOR BLUEBUNCH WHEATGRASS. THE REVISED SEEDMIXES MUST BE SUPPLIED TO THE REGULATORY AUTHORITY WITH 30 DAYS OF APPROVAL.
