Response to CMLRD 10/19/88 Cents on TMI 1987 Annual Report • <br />Page 2 <br />4) Post-Mininc Toooor ohv <br />The Post-Mining Topography map showing regraded areas will be reviewed by the Division during the <br />Annual Report review each year. However, due to the small area covered each year, overall compliance <br />and performance of the yearly regrade cannot be determined. Such a determination will be made by the <br />Division during bond release reviews and inspections. The yearly review will be made to determine gross <br />variations from the approved post-mining topography. <br />No response is necessary. <br />5) Surface Water Date <br />The surface water sampling sites cannot be located on the Hydrologic Maps. These sites need to be <br />included on a map. <br />As presented in Section 4.0, pg. 4.1, of the Annual Hydrology Report, the surface water monitoring <br />sites are shown on map 2-3. In 1989, the sites will be shown on the Annual Hydrology Report Map <br />(Sec 2.0). <br />6) Drainageway Reconstruction <br />As the drainages were reconstructed in 1987, data is not yet available to evaluate the success of the <br />different methods and applications used. The reporting process outlined in this section should provide <br />data to evaluate the drainages in the future. <br />The 1988 Annual Report will contain the information obtained during the year on 1987 drainageway <br />reconstruction work. <br />7) Livestock Ponds <br />Several areas show a clustering of livestock ponds. These areas have been copied for reference. Area A <br />has 4 ponds in 8 acres. Area B has 11 ponds in 30 acres. This concentration of ponds is not needed for <br />livestock watering. If Trapper wishes to use this concentration then some of the ponds will need to be <br />removed prior to bond release to lower the density of ponds. <br />Section 3.6.3.8 of Trapper's permit discusses livestock ponds and pond density criteria. As <br />discussed in this section, pond densities may not exceed an average of one pond per ten acres. <br />The use of an average allows for the construction of a higher pond density where topography is <br />steep and runoff may be greater. Also, the importance of pond clusters from a hydrologic <br />perspective is that flows at stream channel junction points are effectively controlled and the <br />maximum amount of watershed is available to contribute to water storage at these points. <br />We believe that the approved plan for location and construction of livestock ponds in our permit is <br />founded on sound land management principles. Also, removal of any pond (other than showing it <br />promoted hydrologic instability) to be wrong. As discussed in the attached correspondence from <br />the Soil Conservation Service and the previous landowner, pond removal would not be in the best <br />interests of wildlife or future livestock grazing. <br />~I~a,,. <br />
