<br />' DISCUSSION <br />According to the Mountain Coal Company discharge permit (CO-0038776), an acute WET test is <br />' failed whenever the LCSO, which represents an estimate of the effluent concentration which is <br />lethal to 50% of the test organisms in the time period prescribed by the test, is found to be less <br />than or equal to 100% effluent. <br />' By this definition, the results of this bioassay indicate that effluent from outfall 017 is not <br />acutely toxic to fathead minnows or Dnpltnia magna survival. Therefore, Mountain Coal <br />t Company is in compliance with the acute WET portion of its Colorado State Discharge Permit <br />for the first quarter of 2001. <br /> <br /> <br />1 <br />1 <br /> <br /> <br />1 <br /> <br />i <br />COMMERCIAL TESTING SENGINEERING CO <br />~ F,~ LTA <br />Original Watermarked For Your Protection a+c< gyp, <br />
