Team, lam writing to again confirm our meeting which is scheduled for next Wednesday October 7th at 2:00 pm. We have decided to hold the meeting at City Hall but due to rapidly evolving events I will wait until early next week to put out an agenda. In general, we expect to update the most recent water status in order to get everyone on the same page, and then have a targeted agenda that points at both a short term and long term goals. In staying consistent with our other meetings we anticipate a full sharing of information along with open discussion and a clear direction going forward. Darren Lytle of the EPA has committed to being at the meeting and Marc Edwards of Virginia Tech has agreed to call in. Please email me if there are any questions. Thank you, Technical Advisory Team, I am writing to inform everyone that we have scheduled the next Technical Advisory Committee meeting to be Wednesday October 7" 2015 from 2:00 — 4:30 pm. We are extending invitations to Mare Edwards of Virginia xxxEND_PAGE:deq24_b501_1299_1300_1 Tech along with two lead experts from the EPA (Darren Lytle & Michael Schock) to become a part of the technical team and we are hopeful that they will all be present at the upcoming meeting. At the meeting we will discuss an overview of the City water system, compliance with the Safe Drinking Water Act, lead concerns, corrosion control, water testing, public education, capital improvement plans, the KWA pipeline, and next steps. I will forward a specific location and agenda in the near future but we are firmly committing to the time and date. As with previous meetings we look forward to this group having positive dialogue that will benefit the community.

Technical Advisory Team, lam pleased to report that the City of Flint has officially returned to compliance with the Michigan Safe Drinking Water Act and we have received confirming documentation from the DEQ today. The GAC filtering was installed on time and was instrumental in our ability to maintain an average level under the MCL. We anticipate that we will have no further notices going out. Recent testing has raised questions regarding the amount of lead that is being found in the water and I wanted to report to you our current status. At the onset of our plant design, optimization for lead was addressed and discussed with the engineering firm and with the DEQ. It was determined that having more data was advisable prior to the commitment of a specific optimization method. Most chemicals used in this process are phosphate based and phosphate can be a "food" for bacteria. We have performed over one hundred and sixty lead tests throughout the city since switching over to the Flint River and remain within the EPA standards. We are currently designing an optimization plan with the engineering firm that will be presented to the DEQ and upon approval we expect to have it implemented by January 2016. It is worthwhile to note that the DEQ has reported that other cities have taken years to complete an optimization plan and we anticipate having a plan in place over the next four months. 1 xxxEND_PAGE:deq18_b127_1239_1240_1 It is also worth noting to this group that there are different lead testing methods used within industry and the city remains consistent with the most recent EPA approved testing method which can produce different results than other methods. We hope to schedule another TAC team meeting for late September or early October, I will attempt to keep everyone informed and look for the best dates. We are inviting additional EPA experts to become a part of this committee. Thank you, Howard Croft Public Works Director City of Flint 1101 S.

Technical Team, | am writing to provide you an update on the City's ongoing plan to improve the water quality in the City of Flint. This morning, the U of M Flint announced that recent testing showed 48M levels slightly above the : in two of its buildings. The City responded to this recent information of concern with increased flushing in the area where subsequent internal tests have shown the levels to have subsided to under than 80 B86. The ‘Ff 84 level leaving the water plant is currently in the 45 -55 #6 range and in areas with minimal circulation the level can rise by the time it reaches a tap. The installation of new filter media at the water plant which is designed to greatly reduce the EE HV level in the plant is ahead of schedule and is expected to be installed by mid-July. The DEO has approved the design and actual testing by the vendor over the past two weeks has veriieg that the selected media should work. This is expected to have an immediate impact In addition to the filter installation, we have engaged in increased valve exercising over the last two months and have checked over half of the 7,000 valves in the system. The valve turning has a tendency to result in temporary water discoloration but increases the overall water circulation and identifies areas where valves are inoperable. Our annual Consumer Confidence Report will be distributed in early July and will contain significant information about the water system. We will also include the notice of our recent quarterly testing in 1 xxxEND_PAGE:deq16_b5_0892_4900_0241 sostoasrate which all eight sites were verified to be under the MG but the running average at one site required a notice to be sent. | will email everyone when we schedule the next The team meeting which we have currently targeted for mid-August.

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.
