.NOT BE SrLHFLED LN 'TNE FUTURE. TilE REVISED REFEREA~CE ARE.'A, AS h~ELL AS THE DRY h]EADOW AREAS TO BE AFFECTED, SHALL BE S,''PLED BY SEPTEMBER 1, 1982 FOR COVER, PRODUCTION, AND WOODY PLANT DENSITY USING THE d1ETHODS IDENTIFIED IN THE APPLICA- TION FOR THE BASELINE REFERENCE AREA SURVEY. NO SURFACB DISTURBANCE OTHER TI7AN TFIAT NECESSARY FOR THE I.`FSTALLATION OF THE DIVERSION DITCH SYSTEM SHALL OCCUR ON TFIE PROPOSED UPPER TERRACE DRY hfEADO[d AREAS OF DISTURBANCE PRIOR TO COFiPLETE7ON OF ALL VEGETrl TION SAMPLSNG REQUIRED HEREIN. T11E VEGETATION CHARACTERISTICS OF THE REVISED REFERENCE AREA SHALL BE STATISTICALLY CO4IPARED SO THOSE OF THE CORRESPONDING AFFECTED AREAS USING THE PROCEDURES DISCUSSED IN THE APPLICATION. A SPECIFIC PLAN SHALL BE DEVELOPED FOR THE DRY MEADOW REFERENCE AREA TNAT WILL ENSURE THE PROPER MANAGEMENT OF THIS AREA THROUGHOUT THE LIFE OF THE MINE. TFfE DRY hfEADO[d MANAGEMENT PLAN SHALL INCLUDE hfEASURES TO ENSURE THAT THE VEGETATION T}'PE REMAINS ESSENTIALLY UNCHANGED FROM 'lHE PRIMARILY HERBACEOUS VEGETATION STRUCTURE THAT EXISTED AT THE TIME OF THE 1980 REFERENCE AREA BASE- LINE INVENTORY. PRIOR TO COMPLETION OF THE BASELINE INVENTORY FOR THE DRY MEADO[J COMMUNITY, THE PROPOSED DRY MEADOW AFFECTED AREAS SHALL BE MANAGED IN THE SAh1E WA}' AS THE REVISED DRY AfEADO[d REFERENCE AREA. THE REVISED REFERENCE AREA MAP, ALL DATA AND ANALYSES, AND THE REFERENCE AREA MANAGEMENT PLAN SHALL BE SUBMITTED FOR APPROVAL TO TFFE DIVISION BY DECEMBER 1, 1982. NOTE: This stipulation has also been revised by OSM as follows: 39. Prior to august 1, 1981, the applicant shall select, in consultation with the Colorado MLRD and OSM, appropriate areas to increase the size of the existing dry meadow reference area from 0.8 acres to approximately 2.0 acres. The enlarge dry meadow reference area shall be mapped at a scale of 1" = 100' so as to clearly indicate those areas within the revised reference area that will not be sampled in the future. The revised reference area, as well as the dry meadow areas to be affected, shall be sampled by September 1, 1982, for cover, production and woody plant density using the methods identified in the MRP for the baseline reference area survey. No surface disturbance other than that necessary for construction of the peripheral diversion ditches (as discussed with the applicant) shall occur on the proposed upper terrace dry meadow areas of disturbance prior to completion of all vegetation sampling required here- in. The vegetation characteristics of the revised reference area shall be statistically compared to those of the corresponding affected areas using the procedures discussed in the P1RP. A specific plan shall be developed for both the dry meadow and wet mixed shrub reference areas that would ensure the proper management of these areas throughout the life of the mine. The dry meadow management plan shall include measures to insure that the vegetation type remains essentially unchanged from the primarily herbaceous vegetation structure that existed at the time of the 1980 reference area baseline inventory. Prior to completion of the baseline inventory for the dry meadow community, the proposed dry meadow affected areas shall be managed in the same way as the revised dry meadow reference area. During the 9th and 10th years of the bond liability period, the revegetated and reference areas shall he managed in the same way. The revised reference area map, alI data and analyses, and the reference area management plans shall be submitted for approval to the regulatory authority by December 1, 1982. 2.
