Review Checklist for Discharge Monitoring Report (DMR) Requirement Requirement Requirement citation complied with ? Comment es/no 1. Timely CDMG regulation submittal of DMRs 4.05.13(2)(a)(iii) yes None to CDMG DMG considers Section 4.05.13(2)(a)(ii) to require reporting of any NPDES exceedance to DMG within 5 days after the permittee receives its analytical results indicating 2. Timely the exceedance. Under this reporting to CDMG CDMG regulation requirement, the manganese of any exceedances 4.05.13(2)(a)(ii) °O exceedance and WET test failures that of effluent occurred in August should have been limitations reported to DMG some time before 9/5/02. DMG received the report on 9/30/02. The permittee has been advised of the need for more timely reporting of exceedances (see attached letter . As in occasional past months, the discharge standard for manganese was exceeded at outfa11004 (Moffat pond). The potentially dissolved maximum limitation is 0.55 mg/1; the August sample measurement was 1.00 mg/1. The 3rd quarter WET test failed at outfa11007 which is fed by spoil spring #1. The WET limitation is less than a 100% solution of the effluent shall not 3. Compliance kill 50% of the test organioms. A 49.7% with Federal and effluent solution killed 50%. Accelerated State water quality CDMG regulation testing verified the toxicity level of the laws that pertain to 4.05.1(3) no effluent. The toxin was identified as discharges of calcium sulfate. surface water CWQCD plans no enforcement action for the WET test failure and is sending a letter to the permittee regarding the manganese exceedance (e-mail from Carla Lenkey, 11/26/02). I have e- mailed CWQCD to determine the current status of manganese and sulfate standards on Segment 13c of Trout Creek, in light of the permittee's successful petition to CWQCC in early 2002 to remove those standards from that se ment.
