(Kaiser) is submitting the following vegetation sampling protocol to comply <br />with CDMG guidelines pertaining to Phase III bond release applications. Kaiser proposes to condtcci <br />vegetation sampling in June of 2004, year ten plus two of the bond liability period, at the Chimney <br />Rock Mine, Permit Number C-81-023. Sampling will be conducted on two reclaimed Iand ttnits; the <br />Barren Ridge/Revision 1, and the East Pit. Sampling will also be conducted on the Dryland <br />Reference Area. Vegetative cover, herbaceous production, and species diversitywill be evaluated on <br />all areas sampled in accordance with the requirements specified in the mine pernrit. <br />The Chimney Rock Mine is a relatively small stuface coal mine located in Archuleta County off <br />State Highway 151, approximately 17 miles southwest ofPagosa Springs, Colorado. The mine is in <br />Sections 29 and 30, Township 34 North, Range 4 West, with a penni[ area of 170 acres. <br />Methods to measure vegetative ground cover, herbaceous production, and species diversity are <br />discussed in the following sections, and are approved in the permit document. <br />Random Sample Locations <br />Vegetative cover and herbaceous production will be sampled on each reclaimed area and the Dryland <br />Keference Area using 50-meter point-intercept transects that are randomly located and oriented. <br />Sample locations for the point-intercept transects were generated using a grid system overlain on <br />maps of the reference and reclaimed areas. Random numbers were generated using the Microsoft <br />Excel 2000 Version 9.0.2720 random number generator. The resulting random numbers table <br />established the coordinates for transect origin and compass bearing. Sample locations will be <br />determined in the field by pacing from recognizable landmarks. <br /> <br />
