MCC's failure to comply with the Permit effluent limitations, as identified above in paragraph 16, <br />constitutes violations of Part I.A.1 of the Permit. <br />Failure to C" 11 with Whole Effluent Toxicity Requirements <br />18. Pursuant to Part I.A.5(a) of the Permit, MCC is required to perform routine whole effluent toxicity <br />testing ("WET") on a quarterly basis. The WET testing shall consist of an acute 48-hour WET test using <br />Daphnia magna and an acute 96-hour WET test using fathead minnows. The results of the WET test <br />are to be reported by MCC on the DMRs. <br />19. Pursuant to Part I.A.5(c) of the Permit when a routine WET test is failed, MCC must: 1) conduct a <br />Preliminary Toxicity Incident ("PTr')/Toxicity Identification Evaluation ("TIE") investigation; or, 2) <br />conduct accelerated WET testing using the single species found to be more sensitive. <br />20. Pursuant to Part I.A.5(b) of the Permit, upon receiving a routine WET test failure result, MCC must <br />notify the Division within fourteen (14) calendar days of the routine WET test failure and provide a <br />statement as to whether the PTYr1E investigation or accelerated testing is being performed. <br />21. Pursuant to Part I.A.5(c) of the Permit, accelerated WET testing shall be performed at least once every <br />two weeks for up to five tests until two consecutive tests fail or three of five tests fail, in which case a <br />patter of toxicity has been demonstrated. If a patter of toxicity is found, a PTI/TIE investigation is to <br />be performed. <br />22. Division records establish that MCC failed routine WET testing during the following monitoring <br />periods and MCC failed to perform either a PTUTIE investigation or conduct proper accelerated WET <br />testing using the single species found to be more sensitive. <br />Mountain Coal Company, L.L.C <br />Compliance Order on Consent <br />Page 5of13
