5. On Map 2.04.10-2, titled "Adjacent Vegetation", there is a mapping unit identified as JSB <br />that is not defined in the legend. Please add this mapping unit to the legend and define this <br />mapping unit. <br />Response - Vegetation Mapping Unit JSB corresponds to the Juniper Sagebrush <br />Vegetation and the symbol as well as the name of this vegetation type has been added to <br />the legend of Map 2.04.10-2. <br />6. Rule 2.04.10(2) requires reference areas to be shown on a map. Neither proposed reference <br />area is located within the proposed permit area. The maps illustrating the proposed <br />reference areas, Map 2.04.10-3 and Map 2.04.10-4, do not show where the reference areas <br />are located with respect to the proposed permit area. Please include a map or a drawing <br />showing the location of the proposed reference areas relative to the proposed mine location. <br />Response -This information is shown on the revised Map 2.04.10-3 and Map 2.04.10-4. <br />Comments in the January 26, 2011 Memo from Brock Bowles addressing Rule 2.04.10 - <br />Ventation Information <br />1. Vegetation Sampling, page 2 - It is stated in the text, "map was prepared at a map scale of <br />one inch equals 200 feet and has two-foot contour." The corresponding map, 2.04.10-1 has <br />contour intervals of 5 feet. Please correct text for say contour intervals of 5 feet. <br />Response: The text has been changed to denote that the map depicts a 5 -foot contour <br />interval. <br />2. Transect Locations, page 2 - A 50 meter tape was outstretched along a transect to gather <br />various plant data. This technique was described in great detail for the many different plant <br />communities and in the event that an obstacle obstructed the transect. The transects are <br />documented on Map 2.04.10-1 with a GPS accuracy of less than 1 decimeter. On the map <br />the transects in the wetland areas are about 1/16" long while the transects in all other <br />vegetation types are about 1" long. Please explain why there is a difference in transect <br />length and describe the technique used. <br />Response: In the wetland vegetation type in many instances due to the long narrow linear <br />nature of the areas associated with the drainage swales, it was impracticable to use a 50 <br />meter transect length. In these areas, a 5 meter transect length was used to avoid biasing <br />the transect from repeated bends, realignments and an over emphasis on the possibility of <br />sampling the edges of these areas and to keep it within the sample area. The same <br />random number sample intervals generated along the 50 meter transect were used on the <br />5 meter transect but these intervals were converted to decimeters rather than meters. For <br />example, 4.6 meters was converted to 46 decimeters. An additional discussion has been <br />added to Section 2.04. 10 page 3 which reads: <br />In instances where the transect alignment would have resulted in multiple bends in the 50 <br />meter transect tape, a shorter 5 meter transect length was used. In these instances, the <br />random numbers generated for the 50 meter transect length were converted to decimeters. <br />Response to First Adequacy Review Page 24
