Section 816.116 (a) Continued. <br />Measurement Techniques <br />Success of revegetation on the Eckman Park permit area and the <br />future mining areas for Energy Plines No. 1 and 2 will be measured <br />using the State of Wyoming Department of Environmental Quality <br />Guideline No. 2, (1979). Determination of a success standard for a <br />mine site will begin prior to mining by preparing a range site map <br />and establishing a permanent reference area for each range site <br />whi wi 1 be disturbed by mining. The reference areas are about <br />three a res in size and are Located in representative areas which <br />-~ <br />will n t be disturbed by mitring. Each range site and reference <br />area are then intensively sampled. After mining and reclamation <br />have been completed, the revegetated area will be sampled concurrently <br />with the undisturbed reference areas. Premining and postmining <br />data will then be 'ected to_a series of equations which will <br />-----_r- <br />result in numerical goals for ground cover and plant production. <br />When the cover and production from the revegetated area meet or e:cceed <br />these goals, revegetation standards for success have been met. __ <br />Mapping and sampling procedures for range sites are presented in <br />Section 779.19, Vegetation Information. <br />Establishment and Sampling of Reference Areas <br />Typical areas, closely resembling the range sites which will be <br />disturbed by mining were selected on the basis of soils, slope, <br />aspect, and general appearance. Each reference area contains <br />approximately 2 1/2 to 3 acres. The exact location will be marked <br />with steel posts placed at each of the four corners. <br />Sampling procedures used in sampling range sites will be used to <br />sample reference areas with the exception that transects will be <br />systematically determined. A minimum of 15 transects will be run <br />per reference area. Data from range sites and reference areas will <br />be collected concurrently. <br />816-156 <br />
