<br />I. Dischagt Monitorine Reports -Tables V-I, V-2, V-3, and V-4 summarize the ejJlucnt data reported on the
<br />monthly Discharge Monitoring Reports (OMRs) for OutfalLs 023, 003, 022, and 024 respectively, from the
<br />CEC facility from January 1992 to December 1992. !n the monthly submined DMRs, the permittee
<br />indicated that no discharge had occurred during 1992 from Outfalis 004, 007, 009, 011, 012, 013,014,
<br />015, 016, 017, 018, 019, 020, and 021. These discharges consist of surface runoff from post mining

<br />"~ Limit reflects 30~ay average. Average, minimum, and maximum flows were determined from the 30-day average flaws
<br />reported. The permittee is also required to report instantaneous maximums. Highest value reported was 0.0052
<br />MGD.
<br />at Limit is a 7day average and average, minimum, and maximum concentrations were determined from reported 7-day
<br />overage concentrations.
<br />"' Limit is a 30-day average and average, mininuan, and maximum concentrations were determined from reported 30-day
<br />average concentrations.
<br />"~ Limit is a 7day geometric mean and average, minimum, and maximum reported concentrations were determined from
<br />reported 7-ttay geometric mean concentrations
<br />"' Limit is daily maximum, reported concentrations for the 7-day average and daily ma:imam were all <0.1 mg/l.
<br />"~ Limit it an instantaneous maximum No analyses were run since no visual oil sheen was observed.
<br />~' Limit is a minimum and maximum limitation. Average, minimum, and maximum were determined from reported
<br />minimum and maximum values.
<br />'"' Permit requires the reporting of a 90-day average. Average, minimum, and maximxm concentrations were determined
<br />from the reported St7-day average concentrations.
