Mike, lam sending you and Steve a copy of the letter that we plan to include with the violation notice. This is set to go out early next week and I wanted to get your opinion. We have considered some type of water summary to accompany this as well but I am not certain if I can pull that together in time unless you have a specific recommendation. We continue to post the Monthly Operation Reports online within two weeks after the end of each month. Thank you, Howard Croft Public Works Director City of Flint 1101 S.

TTHM — a byproduct of the water chlorination process — was found to be in excess of state guidelines (80 parts per billion) beginning in May 2014 and continuing into August. As soon as this excess concentration was discovered, we began taking steps to reduce it to within acceptable guidelines. We are pleased to report that we have succeeded in bringing the water to within acceptable guidelines. While we continue to work on improving aesthetic qualities, such as discoloration or odor, you can be confident that the water provided to you today meets all state standards. How did we did do this? With the help of LAN engineering, we upgraded the ozone treatment process at the Water Treatment Plant; increased water main/hydrant flushing to reduce stagnation; conducted small-scale testing of treatment to identify areas of improvement; improved overall plant operations; and enhanced the distribution system through water-circulation modeling. By November, all but one testing site was below the allowable levels and our most recent testing in February showed that every testing site was well below allowable levels, as shown below: City of Flint xxxEND_PAGE:deq16_b5_0892_4900_0387 Water Quality Update The Michigan Department of Environmental Quality (MDEQ) has been monitoring our progress, as noted in its March 5, 2015 letter to the city: “We are encouraged by the results from the most recent round of compliance samples collected on February 17, 2015, which naw show individual TTHM levels at less than half of the 0.080 mg/L standard ot ail locetions throughout the City’s system. Operational Evaluation Reports from December 2014, and February 2015, have identified possible causes and corrective measures for the previous elevated TTHM ievels, which we encourage the City to continue implementing. These madifications have likely contributed in part to the reduction in TTHM levels reported in the most recent querter, and suggest the Cy may be able to achieve compliance with the TTHM standard at all sites by continuing these efforts.” MDEQ However, because MDEQ monitoring of excess concentrations is based on four quarters of test results, we are required to again notify you that based on the most recent four quarters of test results (which includes excess concentrations beginning in April), the City’s annual quarterly testing average is not yet below the state’s allowable average. The attached notice (“Important Information about Your Drinking Water”) includes legally required language that summarizes the situation. Please review it and contact us with any questions. In addition, included in this mailing is a list of Frequently Asked Questions. We also have created a place for regular updates on the city’s website at cityofflint.com. We encourage residents who have concerns about the quality of their water to contact us immediately so on-site testing can be scheduled. If you have questions about this report or would like a test done at your home, free of charge, please call us at 810-787-6537. Maintaining safe water and improving its quality is a top priority, and we apologize for the concerns these notices have raised. We have taken many steps to improve the safety and quality of our water supply and will be taking more. As you may know, we have recently received a series of recommendations from several sources, including a report from international urban water system consultants, Veolia North America. We will be working with our recently created Citizen Advisory Committee and our Technical Advisory Committee to continue making improvements. Please track our progress on our website at cityofflint.com. Sincerely, City of Flint xxxEND_PAGE:deq16_b5_0892_4900_0388

Howard, It appears that my edits were not included in the final letter. The 6" paragraph down should be revised such that residents understand the difference between the Locational Running Annual Average (LRAA) and the results from the individual quarter (Feb 2015) ...to avoid possible confusion when they read the DEQ PN template which states that two of the eight sites are above the TTHM standard (this being based on. the LRAA). Also, the words “annual " average” needs to be replaced with Locational Running Annual Average (LRAA). Michael Prysby, P.E. District Engineer Office of Drinking Water and Municipal Assistance 517 290-8817

Howard et al: Please find my additions (including some Comments) attached using tracked changes based on Mike's version. | like his additions as well especially the LRAA language, although | did have a question on the softening text.

Please call me this week as well, Mike Wright PS: Please add my work email to the current Email list (weight Howard, | made 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.

Hello everyone, - The Genesee County Health Department has made several written and verbal requests for specific information since October, 2014, including a Freedom of Information Act Request on January 27, 2015. The information still has not been received and the city’s lack of cooperation continues to prevent my office from performing our responsibilities. The Genesee County Health Department has the responsibility to conduct Illness Investigations and consider all potential sources, this Is not optional. In 2014, Genesee County experienced a significant increase of confirmed Legionella illnesses relative to previous years. Legionella can be a deadly, waterborne disease that typically affects the respiratory s' (stem. The increase of the illnesses closely corresponds with the timeframe of the switch to Flint ’ River water. ‘The majority of the cases reside or have an association with the city. Also, McLaren Hospital identified and mitigated Legionella in their water system: This is rather _ glaring information and it needs to be looked into now, prior to the warmer summer months “when Legionella is at its peak and we are potentially faced with a crisis. < This situation has been explicitly explained to MDEQ-and many of the city’s officials. | want to make sure, in writing that there are no misunderstandings regarding this significant and urgent public health issue.

Follow Up Flag: Flag for follow up _ Flag Status: Flagged Hello Steve and Mike. As you are aware, the City has undergone extensive upgrades to our Water Treatment Plant and it's associated facilities. Our intentions and efforts have been to operate our facility as the primary drinking water source for the City of Flint. Through consultation with your office and our engineering firm we've developed a system of redundant electrical systems, treatment processes and adequate finished water storage to negate the need for a signed back up agreement with DWSD due to their termination of our contract. Upon inspection of these facilities would you convey your concurrence that there is no regulatory requirement for us to sign a back up agreement with DWSD.
