Highest value reported was 2.302 MGD. ~~ Limit is an instamaneous maximum. No analysts were run since no visual oil sheen was observed. of Limit reflects 30day average/7-day average. Average, minimtun, and maximum concentrations were determined from the reported 30-day and ;ray average concentrations. ~'~ Limit is a minimum/maxirwm limitation. Average, minimum, and maximum were determined from reported minimum and maximum values. R1 Permittee required to report 9th-day average 7DS concentration. Average, minimum, and tnaxrmwn concentrations were determined from the reported 90day average concentrations. ~" Limit reflects 30day avnage/daily maximum. Average, minuruan, and maximum concentrations were determined from the reported 30day averc:ge and daily rrwsimum concentrations.
