really hope my last e-maildoesn't create more problems. I felt obligatedper directiongiven me from my Management to facilitatea successfuloutcometo thisprojectas best I can. I hope I didnot doany unrecoverable damage. I don't think so, but I have had my head in the trenchso much lately,rm notcompletelysure. Below is the responsefrom our water qualityspecialist. I asked her to lookover mywater qualitycomments and the SMP to see if she could findanything I missed. I alsoasked her to lookoverwhat appears to be high copper levels to see if there was somethingwe couldrecommendto helptheir. She essentiallyconcurredwith my findings/commentsregardingbasicwater qualitytreatmentBMPs, and had the attachedcomments related to Cu levels. I do notsee makingthese issuesnow, rather they wouldbe areas of possibleconcernbeyondcompliance withminimumKCSWDM standards. While it is conceivablethat a like-projectwouldbe conditionedto deal with these issuesunder large site developmentreviewprocess, I think it is bestleft to their NPDES or401 permitfor this project to do the further evaluation needed. Note: the highCu levelsare nota situationcreated bythe proposed development,but nothingproposedby the SMP (with possibleexceptionof IWS redirects) isexpected to improvethe situation. Please let me know if you disagree with thisapproach. wKelly. Kelly R.
