III. SURFACE WATER <br />• A. Operational Monitoring Program <br /> The operational surface water monitoring program as approved in the <br /> Nucla Mine Permit is detailed in Appendix A, (Attachment A) <br /> Reduction of Monitoring for the Nucla Strip. The location of each <br /> of these sites and pertinent site information are presented on <br /> Exhibit 1 and Table 2, respectively. Included on this map and <br /> table are those sites which have been established subsequent to <br />- <br />--- <br /> ~ <br />- <br />implementation of the monitoring program outlined in Appendix A. <br /> Specifically, Spoils Springs {il and l12 located immediately to the <br /> west of the inlet to the 001 sedimentation pond have been monitored <br /> since the fall of 1984 and 1986, respectively, for the same <br /> parameters and at the same frequency as the Highwall Spring <br /> described in Appendix A; and surface water monitor-ing-si-te -SW-N7 <br /> located upstream of the "triangle area" has been monitored since <br /> March of 1986 for the same parameters and at the same frequency as <br /> the other surface water sites. In addition to this monitoring, a <br /> semiannual spoils spring survey of reclaimed areas has been <br />• initiated as of this fall (September,1986). It was during this <br /> survey that Spoils Spring N2 was discovered (see Section III.C.S). <br /> This survey also includes those areas to be mined in the scraper <br /> area. Also included on Exhibit 1 are those surface water sites <br /> which have been established for the purpose of collecting baseline <br /> hydrology information for the Nucla East Mine area; these sites <br /> will not be discussed in this AHR. However, Nucla East data which <br /> have been collected through September 1986 and have been input to <br /> the PCC computerized water resources data base are reported in <br /> Appendix B. <br />An additional surface water monitoring site is being considered_ for <br />the Nucla Mine in the post-law reclaimed area above County Road <br />124A-A. Because regrading and seeding in this area will not be <br />completed until the fall of 1988, the monitor instrumentation and <br />location specifics will be deferred until then. Oata obtained from <br />• this site will serve to evaluate the success of reclamation <br />practices with regard to controlling drainage and chemical na d <br />sediment loads from post-law reclaimed area. <br />5 <br />
