Re: call

Mike Marvin Gnagy from Veolia wanted to talk with you about some of the suggestions they were making for treatment here at the plant. He wanted to know what could be implemented right away and what might need permit approval from the MDEQ. They were here running test all week but left yesterday. I have listed his contact number and email below. I would appreciate it if you could get in contact with him so he can finalize his report and send his recommendations to the city administration.

TTHM Violation Notification

Mike, Steve Concerning the violation notification for TTHM's the city needs clarification on the delivery of notification. In the last violation notification for Total Coliform the City published it in the local paper and posted it on the city website, this satisfied the DEQ requirements. Would this be adequate for the TTHM notification? Thank you for your prompt reply concerning this matter. Brent Wright Water Plant Supervisor City of Flint 4500 N. Dort Hwy.
