Technical Team Members, Attached please find the final copy of a letter to the health community along with a Frequently Asked Question list. These documents are ready for distribution among your peers and others. We anticipate mailing out the actual violation notice at the beginning of next week.

Howard, imade a few changes to the draft letter..in red (see attached)... mainly to make a more clear distinction between the locational running annual average and the stand-alone quarter {February 2015) results and how it affects the number of sites in compliance. If you have any questions, feel free to call me. Michael Prysby, PE. District Engineer Office of Drinking Water and Municipal Assistance 517 290-8817

All, We still have not received the violation notice from the DEQ although we expect it any day now. We continue to work on what additional documentation will accompany the letter and still plan to vet that through this group. | We would like to have the notice in hand to verify how it reads before completing our draft copy of accompanying documents. We are planing to have another community advisory group meeting next Thursday March 19th. I will wait to set the next Technical Advisory Meeting date and agenda until after that group meets.

November.pdf; Tech Committee Presentation - Veolia.pdf All, I want to thank everyone for attending our first Technical Committee Meeting yesterday, by all measurements this was a very successful first gathering. I am forwarding everyone an electronic copy of the materials shared yesterday including the presentation by Veolia. As for next steps, I am looking for literature form DR. Rose and from Michael Wight of the EPA to come within the next day or two. I also would like to have specific questions that anyone feels should be included in a bullet point list so that we can move quickly to generate the best responses. Next week I will look to vet with this group the information that we intend to send to the community along with the next violation notice. Our goal is to have documented information in everyone's hands prior to the mailing of the violation. We will also plan to have another meeting very early in April to assess the community response to the upcoming notice, evaluate if there are items coming from the community advisory group that need to be addressed, share the internal water plant progress, and to determine our next steps.

Technical Team Members, This is a reminder of our first meeting date next Wednesday March 4th at Flint City Hall at 2:00 - 4:00 pm. Please bring any questions or goals that you would like to see developed out of the group as we will create the final overarching agenda in the committee. On a side note, our February TTHM test results were re returned from the state lab this morning and all eight test sites are substantially below the MCL. I look forward to seeing everyone on Wednesday. Regards, Howard Croft Public Works Director City of Flint 1101 S.

Revise Tables 2 and.3 on Page 7 to account for proper alignment of DDBP _ samples (results, location, site code). Also, revise statement on Page 1 regarding the number of sites exceeding the TTHM MCL following the 4" -* Quarter sample cycie. . The ozone system was recently repaired. (Page 10 & 19). What is the ozone system’s current production rate? . The city’s hydraulic model (prepared by Potter Consulting) is being updated (Page 16). Is the model currently sufficient in determining proper sizing for the transmission main replacement in DuPont & Bishop Street corridor? (currently sized at 24-inch) (Pages 5, 16, and 20) . Are the potassium permanganate results & conclusions available? - (Pages 4 and 17) . We agree that some reduction in storage volume could be achieved without compromising reliability; however given high usage, main breaks, and “let runs” during the winter, storage volume remains important. We agree with the need to determine adequate storage volume which will likely differ between summer and winter. (Page 15) We agree with the concern of re-circulation of water pumped from the booster pump stations; however, we were recently informed of existing distribution system check vaives to prevent recirculation. These _ appurtenances and their condition need to be confirmed. The hydraulic model may also need to be updated to include these valves. (Page 15) . We concur with the rexommendation to provide the ability to monitor raw - water TOC and PTAP TTHM. (Pages 17 & 18) Page 20 provides 2 options to manage ee age and each option includes reducing the utilized storage volume of the 3 MGAL well to 2 MGAL. ,The - ’ reduction in storage volume limits the WTP’s ability to meet CT under worst case conditions (low temp, high pH, 30 MGD pumping rate from reservoir). . Table 11 on Page 21 outlines an Action Plan for Stage 1 and, Stage 2 actions. Several actions listed in Stage 2 including; repair of ozone system, continued _ valve replacement, and replacement of deteriorated watermains are longer term solutions; however, they need to proceed regardless of the outcome of TTHM reduction. ‘ xxxEND_PAGE:deq27_b336_1832_1944_068 Lockwood, Andrews PLANNING CL FEDEX BMANSERING 526 WEST ALLEGAN STREET Reports Submittal Dats: Thats MITTAL Filing Date code 10F SOUTHAINGEN ROAD cuisteibution H endiogures de ne intgaddad fo-repisite ie hve gets Het xxxEND_PAGE:deq27_b336_1832_1944_069 EXECUTIVE SUMMARY Benn identified as px xxxEND_PAGE:deq27_b336_1832_1944_070 ane xxxEND_PAGE:deq27_b336_1832_1944_071 xxxEND_PAGE:deq27_b336_1832_1944_072 polymer aid KREG S BALY: ¥ xxxEND_PAGE:deq27_b336_1832_1944_073 xxxEND_PAGE:deq27_b336_1832_1944_074 wide xxxEND_PAGE:deq27_b336_1832_1944_075 | xxxEND_PAGE:deq27_b336_1832_1944_076 Hy Stack xxxEND_PAGE:deq27_b336_1832_1944_077 4 SOURCE WATER EVALUATION A.
