ediment pond number 3 and the diversions were removed following the 1990 Bond Release request. Ponds Nos. 1 and 2 were approved as permanent impoundments per TR-06 and in compliance with 4.05.6(14). Information on backfilling and grading can be found in Section 2.08.5 of the permit application. The operation is in compliance with the requirements of this section. XI. Revegetation Two plant communities, big sagebrush and alkali sagebrush, were located within the permit area. Big sagebrush communities are found on the south and southwest facing slopes, whereas the alkali sagebrush communities are found on north and northeast facing slopes. Only the Big sagebrush community was disturbed, therefore only the Big sagebrush reference area will be used for evaluation of revegetation succes~-~ Species diversity, woody plant density, production, and cover standards have been established for assessing revegetation success. These standards were defined as part of satisfying permit stipulation Nos. 18, 19 and 17, respectively, of the permit approval. A woody plant density standard was established to satisfy the requirements of Stipulation No. 19. On October 10, 1990 a technical revision was approved that reduced the required woody plant density to 2000 stems/acre. A stipulation attached to this revision required the submittal of a letter from the land owner consenting to this reduction. This stipulation was satisfied and terminated. On May 22, 1996, the Division approved further reduction of the woody plant density standard to 500 stems/acre. Concurrence for this reduction was received from the surface landowner, Mr. Dale Moore, the U.S. BI.M-ICremmling Resource Area Manager, and from the Colorado Division of Wildlife. An adequate sample will be taken to evaluate properly the woody plant density. Stipulation No. 18 required that a species diversity standard be established. Slurco has proposed to establish a minimum of six (6) species consisting of: three (3) cool season grasses with a combined relative cover of 7-60~, one (1) fort species with a relative cover of I-35 ~, and two (2) shrub species not contributing to overall relative cover. Of the three principle cool season grass species, no single species will comprise greater than 40 percent in relative importance. Sampling of diversity will be obtained during the liability period and will meet sample adequacy requirements. This proposal is in line with baseline data collected in 1979 and 1980. The proposed standard complies with Rules 4.15.8(2), (5) and (6). Canadian Strip Mine, C-81-026 25 December 5, 1996
