Box 459 Natural Resource Trustee <br />Florence, CO 81226 <br />Re: Scope of Work for the Year Nine Revegetation Sampling at the Marr Mine - <br />Adequacy Review <br />The Division of Minerals and Geology (Division) has reviewed the Man Mine <br />revegetation-sampling proposal. Generally, the plan is acceptable, however many details <br />need to be clarified. The Division has the following adequacy review comments. <br />Please list the four reclaimed areas to be sampled. In the final report please <br />provide a map delineating each area and show all the transect locations. <br />Please delineate the reference areas on a map and show transect locations. In the <br />final report describe how the reference areas are weighted to determine the <br />revegetation success standazd. <br />The approved permit states there are four reference azeas. The monitoring report <br />submitted by ESCO in 1999 explained that the azea originally designated as the <br />Sagebrush-Gravel reference azea was combined with the Treated Sagebrush <br />reference area. However, the permit has not been revised to indicate this change. <br />Please revise the permit with the reference area locations and the reasoning <br />for combining reference areas. The map will need to be updated to show the <br />all reference area locations. <br />4. Please describe how each transect is randomly located within each reclaimed azea <br />and within each reference area. <br />5. Please specify the type of plant cover that will be collected, i.e. Current year <br />growth listed by species, litter, rock etc. First hit will be recorded. (Subsequent <br />hits can also be collected, but do not need to be.) <br />6. Please specify the details of production sampling. For example, current yeazs <br />herbage yield. Since three quadrats will be clipped for each transect, the detailed <br />Office of Office of Colorado <br />Mined land Reclamation Active and Inactive Mines Geological Survey <br />
