AR226-2564 Andrew S'Rartlen "" ' ' '"11/6T/20dl'03':59PM'i To: cc: Subject: wen(worth.wlllfam@epamail.epa.gov Update on Things Bill, A couple of things I wanted to update you on. First, we are preparing a letter that addresses some of the items raised by the USAGE in their draft review of the Wash Works model. We thought it would be best to have a response in the file (ours and yours) that clarifies some things as well as proposes action steps for upgrades. You should see this next week. On another matter, the Consent Order. During a recent meeting with DEP, the EPA folks on the line nixed my Idea to include Jack Hwang on the <3W Steering Team, and instead inserted Roger Relnhart and Garth Connor (from the Multimedia Gp.?). I guess you can take that up with them if you disagree. I thought Jack was a natural based on his main plant experience, they should at least get his input. Its my guess the CO will be effective around Nov. 15. Oh yes, regarding C-8 analytical method upgrades. Recent analysis of plant and LPSO drinking water samples using the new method (performed using new LC MS/MS method by Exygen Labs in State College, PA) resulted in nearly equiveient readings of historical (all in the .2 to .7 ppb range) levels, but QA/QC was all within required criteria. Needless to say, we're pleased with this. I'll ultimately get you some Info. on this method so you can have you're CRL lab review. That's all for now. Let me know if you have any questions.
