Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Pineda <br />Director <br />The Colorado Division of Reclamation, Mining, and Safety (CDRMS) has reviewed and found the <br />above referenced reports to be in compliance with Rule 4.05.13(2). The fourth quarter 2013 Discharge <br />Monitoring Reports were received by the Division on 27 January 2014. <br />All outfalls permitted under COG - 0048275 discharged during the fourth quarter 2013. No exceedances <br />were noted. <br />The well pump test permitted under COG - 603191 occurred in November 2011. No further discharge <br />has occurred since. Based on coorispondance received via email from CDPHE Permit COG - 603191 has <br />been terminated effective October 1, 2013. The Fourth Quarter 2013 DMR will be the final DMR <br />associated with this site. <br />Whole Effluent Toxicity tests were collected for analysis during the fourth quarter. The tests indicated <br />that the effluent was not acutely toxic to Pimephales promelas or Ceriodaphnia dubia. <br />In addition, a revised Second Quarter 2013 DMR was submitted as an inaccurate value for selenium was <br />noted on the original second quarter DMR. <br />If you have any questions feel free to contact me.
