-51- r~ IF THE ANALYSES OF THE IN-PLACE MATERIAL INDICATE THAT SUCCESSFUL REVEGETATION CANNOT BE ATTAINED, THE PERMITTEE MUST EITHER APPLY APPROPRIATE AMENDMENTS TO MAKE IT SUITABLE OR IMPORT SUITABLE MATERIAL. IF AMENDMENTS OTHER THAN NITROGEN, PHOSPHORUS, POTASSIUM, SULFUR, OR IRON ARE REQUIRED, THE PERMITTEE MUST SUBMIT THE RESULTS OF APPROPRIATE TESTS TO PROVE THE AMENDMENT MATERIAL IS SUITABLE FOR REVEGETATION. THIS PLAN WILL BE SUBMITTED AS A REVISION TO THE PERMIT. With satisfactory resolution of the above stipulations, the proposed operation will be in compliance with the requirements of this section. XII. Vegetation - Rules 2.04.10, 2.05.4(2)(c) and 4.15 Baseline vegetation information for the Allen Mine submitted by the applicant can be found on pages 2.04-15 through 2.04-16 of Vol. I and Exhibit 12 of Vol. II. The revegetati,on plan is found on pages 2.05-21, and 2.05-30 through 2.05-33 of Vol. I and Exhibit 18 of Vol. II of the permit application. These sections have been reviewed by the Division for compliance with the requirements of these sections. The applicant has provided two baseline vegetation inventories, one conducted in 1980, the second in 1981. The 1980 survey did not sample pre-mine vegetation communities, but selected "reference areas" and sampled within these "reference areas". The 1981 survey sampled affected areas and reference areas for ponderosa pine-oak, ponderosa pine-oak-Douglas fir, and willow carr communities. The applicant has provided information on cover, productivity, woody plant density, species composition, and a vegetation map, The applicant has not provided a discussion of the acreages of each vegetation type which have been or will be disturbed at the Allen Mine during the remaining life of mine. This information is required to determine the adequacy of the baseline sampling and reclamation/revegetation plan. In order to comply with Rule 2.05.3(2)(b), it is therefore a stipulation of the permit that: Stipulation No. 20: THE PERMITTEE SHALL SUBMIT TO THE DIVISION A TABLE OF THE ACTUAL AND PROPOSED ACREAGES OF DISTURBANCE FOR EACH VEGETATION TYPE AT THE ALLEM1 MINE WITHIN 30 DAYS OF PERMIT ISSUANCE. FOR THOSE VEGETATION COMMUNITIES (PONDEROSA PINE - OAK, PONDEROSA PINE - OAK -DOUGLAS FIR, OR WILLOW CARR) WHICH COMPRISE 5 PERCENT OR LESS OF THE LIFE-0F~+II NE AFFECTED ACREAGE, NO ADDITIONAL BASELINE SAMPLING WILL BE REQUIRED. In the calculation of adequate sample size for parameters of each of the communities, the applicant used a precision value of 0.2 instead of the 0.1 value acceptable to the Division. Use of this value caused the applicant to undersample each parameter for each vegetative community. Therefore, the applicant has not supplied an adequate description of the affected vegetative communities mentioned above in accordance with Rule 2.04.10.
