Spring that does not contain perennial surface flow before discharging to the San Miguel <br />River. <br />The Drainage Design Plan has been developed for this site and can be found in <br />Appendix III. <br />(11) Surface Water Quality Data <br />Mining at LP -21 does not have any effects on surface water as discussed above; therefore, <br />there is currently no need for a monitoring plan. <br />(12) Water Quality Monitoring Plan <br />Future use of water from the San Miguel River could include municipal and irrigation <br />applications. As discussed above in (7) and (8), it is not anticipated that the LP -21 mine <br />will have any adverse effect on any surface waters. Thus, it is not necessary at this time <br />to implement a monitoring plan. <br />(13) Climate <br />The closest weather stations to the LP -21 mine are located in Uravan, Colorado, <br />approximately 5 miles north of the LP -21 mine and in Bedrock, Colorado, approximately <br />9 miles west of the mine site. Available precipitation and pan evaporation data for these <br />stations is presented in Exhibit K - Climate. <br />13.1 Temperature <br />Taking the average temperatures of these two NWS meteorological stations shows that <br />the temperature range in this area is from 54° to 96° F in the summer and from 17° to 46° <br />F in the winter. The overall average annual temperature at these two stations is 52° (See <br />Exhibit K - Table 1) <br />13.2 Wind Speed <br />Wind speed data was not available at the Uravan or Bedrock meteorological stations. <br />Longer term wind speed records are available from the BLM and the Boise Interagency <br />Fire Center Remote Automatic Weather Station (RAWS) in Nucla, Colorado (NUCC2), <br />elevation 5860 ft. Based on the available data from the Nucla station from 2002 through <br />2012, the average annual wind speed is 5.0 mph. Winds are primarily westerly winds. <br />As indicated in the climate data, precipitation for the Uravan station is 12.57 inches per <br />year for the Bedrock station 10.77 inches per year, whereas the evaporation is <br />approximately 43 inches per year. Taking the evapotranspiration rates of vegetation into <br />consideration, there is very little water for subsurface recharge. <br />O'Connor Design Group Inc. U - 18 <br />
