In response to a request from the company to temporarily allow release of minewater through outfall 003, the Division sent a letter to the company dated Januarv 25, 1988 authorizing such a discharge. The letter of January 25 specified that the effluent limitations for outfall 003 (durinc the temporary release) would be the same as the limits presently in the permit for outfall 002. The Division hereby amends the Notice of Violation to add the c,, i ~ ,....t ., ,. .,, _ fl ..' ~.s, You are further notifed that the information contained in naracraphs 16 and 17 of the Findings of Fact constitute violations of Part I A. 1. of the permit as follows: 1. The total suspended solids concentrations on Januarv 31 and March 29, 1988 at outfall 002 and the TSS concentrations on February 3, Februarv 5, February 6 and February 10, 1988 at outfall 003 exceed the daily maximum concentration allowed by the permit of 70 mg/1, based on a single, grab sample. 2. The monthly average concentration of TSS for outfall 002 for March, 1988 and for outfall 003 for February, 1988 exceeds the monthly average concentration allowed by the Hermit of 35 mg/1, based on an average of three or more samples taken during a 30-day period. 3, The pH on Januarv 15 and March 3, 1988 at outfall 002 exceeds the maximum pH allowed by the permit of 9.0 s.u., based on a single, grab sample. -2-
