Tom - Please arrange with ORD experts to work directly with MDEQ and provide Tim & | a status update by 3:00 pm today. Thanks

| had a conversation with Dan Wyant today about the situation in Flint. We talked about the need for expedited implementation of corrosion control and making sure that appropriate testing protocols are used. He asked that EPA provide technical assistance to MDEQ to do this. Would you please arrange for the ORD people on the Flint Technical Advisory Committee to reach out to provide direct assistance to MDEQ, as well?

Aftiached is our draft letter to Flint regarding their lead and copper rnonitering results and 90" percentile determination for ther initial 2 sh-maonih LCR monitoring periods after the city converted from Detroil’s conventional treatment of Lake Huran to softening of the Flint River. This letler includes our directions for the ensuing steps and our recommendations as far as corrosion control optimization. Please provide any comments you may have by the close of business on Friday, August 14". We realize this response time is short, but we intend fo deliver this letter to the city on Monday, August 17".

Date: Tuesday, July 21, 2015 10:52:00 AM Thanks Tinka. During discussion issue #1, we would like to discuss our (hopefully, mutual) understanding of the timeline for next steps. Also, while we understand your concerns with the overall implementation of the lead and copper rule(s); we think it is appropriate for EPA to indicate in writing (an e-mail would be sufficient) your concurrence that the city is in compliance with the lead and copper rule as implemented in Michigan. This would help distinguish between our goals to address important public health issues separately from the compliance requirements of the actual rule which we believe have been and continue to be met in the city of Flint. And finally, we would also like to discuss our concern that the draft report was released by EPA and that we (DEQ) obtained a copy of the report from an outside (ACLU) website. Liane J.

Hi Liane — tn preparation for our call today we’ve prepared an agenda (attached) with some background and discussion points. Please let me know if you have other items you wish to discuss. Thanks Tinka G. Hyde Water Division Director USEPA W-15J , 77 W. Jackson Blvd Chicago, IL 60604 Office: 312-886-9296 Q co: xxxEND_PAGE:deq27_b311_1434_1438_2 Notes on Call with MDEQ on July 21, 2015 MDEQ Implementation of LCR Rule and Flint Issues Issue #1: Is there a public health concern regarding lead in Flint or other regulatory requirements? ° The 90" percentile results of the 2™ round of monitoring was 11 ppb. ¢ The population has dropped to under 100,000 and therefore the 1" round of 6-month monitoring was done for 100 samples, but the 2™ round only needed 60 samples, e Customer-requested samples were included, but MDEQ did n e Tinka asked about the timeline for Flint to switch over to th pipeline is under construction and scheduled to be co and thinks a more realistic timeframe is October 2016 e MDEQ explained that Flint would have 18 months esion control study and the complicating factor of switching over to Lake ; fecontrol study be based onthe Lake Huron source?

MDEQ said the ly 2016. MDEQ expects some delays p fatioiis, allow for the study requirement for Flint and additig phosphates, Region 5 will look into this Issue #2: Discuss optimal corrosion control requirements Discussion Items: e MDEQ explained that they did not treat the switch to Flint River water as a “new system”, but as anew source. It is their understanding that 2 rounds of 6-month monitoring is still needed to characterize the water quality. They don’t know what is optimized until those 2 rounds of 6-month monitoring are completed. xxxEND_PAGE:deq27_b311_1434_1438_3 Next Steps: Region 5 noted that under 141.81(b)(3)(iii) that any system that has been deemed optimized must notify the State of any long-term change in treatment or the addition of a new source. The State must review and approve the change and may require any such system to conduct additional monitoring or other action to ensure that the system maintains minimal levels of corrosion in the distribution system. The State’s requirement for 2 additional rounds of 6-month monitoring would fall under the “additional monitoring” prescribed by the State and not the initial 2 rounds of 6-month monitoring for new systems. Region 5 explained that they have talked to HQ about the interpretation of regulations and believes that systems that have been deemed optimized need to “maintain” corrosion control. The Region agreed to provide supporting regulatory citations for the language about maintaining corrosion control. Ed Moriarty in OGWDW is also consulting OGC on this topic and t GC opinion will also be shared. MDEQ mentioned that there are other communities that m e the Detroit system or connect to the new Lake Huron pipeline, but many of those either don; eat for corrosion control or will be sion control for additional communities connecting to the Lake Huron pipeli i {further after receipt of the Lead compliance sampling proced ic comply with Federal SDWA requirements which calls for a minimi i ch. there is no water used from the tap the sample is taken from : The Michigan pre- ped as a way to ensure that sampled faucets were not stagnant for an sid the targeted 6 hour (i.e., rarely used faucets or whe : : eriod of time). garding the 2 rounds of 6-month monitoring results that exceed 5 control study.

MDEQ mentioned tapping Mike Shock for help with this in the interim. Region 5 commented that we now have a path forward for Flint despite a difference of opinion on whéther the regulations required Flint to “maintain” corrosion control treatment when they started serving treated water from the Flint River. ; MDEQ and Region 5 agreed that after Flint implements corrosion control treatment, when they switch back.to Lake Huron water, they will need to.continue the corrosion contro! treatment while conducting monitoring to determine if this treatment is optimized with the new Lake Huron water quality. xxxEND_PAGE:deq27_b311_1434_1438_4 e Region 5 will. get back to MDEQ once it gets HQ/OGC’s opinion on the need to “maintain” corrosion control treatment once a system is. deemed optimized. © MDEQand Region 5 agreed that other communities currently implementing corrosion control treatment and change sources will need to continue to provide corrosion control treatment and conduct monitoring to determine whether the treatment is optimized with the new source water quality. : : © Region 5 will research and get back to MDEQ on the 141.81 (3)(b)(5) citation and the ability to waive a CCT study. xxxEND_PAGE:deq27_b311_1434_1438_5

Hi Liane — I’m following up on the voicemail | left for you earlier today. I’m also copying Carrie Monosmith as | did get a chance to chat with her. In advance of our call scheduled for 7/21/15, | wanted to provide you with an update related to water quality challenges in Flint. | understand that some discussion occurred on June 10" with Tom Poy and staff during the semi-annual call regarding MDEQ’s implementation of the LCR rule and the status of Flint. The Region is concerned about the lead situation in Flint and suggested that additional ORD assistance could be provided to Flint’s Advisory Committee. We understand that the city is finishing up its second set of 6-month initial monitoring and | have scheduled a call with you on July 21st so we can discuss the Flint situation in more detail. As you know, my staff have been out to Flint to collect samples and data which we felt could uniquely inform the NDWAC process and ultimately better inform the LCR rulemaking. Tom Poy asked Miguel Del Toral to prepare a report summarizing the visits and findings. Last week Miguel completed a draft interim report and provided it to management. Once Miguel addresses our comments, we will provide you with a copy of that report. In most cases, an internal EPA memo would not be distributed outside the agency, but given his interaction with the homeowner for one of the sampling locations, Miguel has shared a copy of the draft interim report as a courtesy with this Flint resident. Based on Miguel’s initial analysis, elevated lead levels were found at this residence. In addition, it appears that the source of the lead may be from outside the home (Note: plumbing in the home is largely plastic). Please know that Region 5 management is still being briefed on the lead issues in Flint and we look forward to the opportunity to discuss the situation with you in more detail so we can better characterize what MDEQ is already doing in Flint and how public health protection can best be provided to the citizens of Flint. If you would like to discuss this in advance of our call, please feel free to contact myself, or Tim Henry (312-886-6107). Thanks Tinka G. Hyde Water Division Director USEPA W-15J 77 W.

Tinka/Tim: We (R5 and OGWDW) had a call with the White House Strong Cities/Strong Communications Flint Liaison this morning. Below are my notes of the discussion. Flint Drinking Water Conference Call — 3/9/15 Participants: R5/GWDWB — Tom Poy, Jennifer Crooks HQ/OGWDW - Eric Burneson, Elizabeth Corr, Becki Clark, Roy Simon White House Strong Cities/Strong Communications Flint Liaison — Paul Joice (HUD) (works directly with Flint’s mayor) Tom Poy summarized what has gone on with Flint’s Drinking Water: - Switching from finished Detroit water (Lake Huron source) to Flint River in April 2014. - Karegondi pipeline will provide Flint with raw water from Lake Huron when completed in 2016. - MDEQ has been working with Flint from the start to get their treatment plant running properly. - Summer 2014, Flint had an E coli detect because of distribution system issues (broken valves causing stagnation of water). o Chlorine levels increased which increases potential of forming disinfection byproducts when chlorine reacts with organic carbon. o Flushing increased which can stir up sediment in the water mains. - December 2014, Flint exceeded the MCL for TTHM which is based on a running annual average (RAA) (avg of 4 quarterly samples). - MDEQ has worked with Flint since August 2014 when chlorine levels were increased, to tweak operations to reduce TTHM formation. xxxEND_PAGE:deq21_b561_1590_1592_2 - February 2015 sampling has TTHM concentrations well below the MCL but since compliance is based on an RAA, it will take another quarter or two of lower concentrations to make the average go down below the MCL. - Flint has hired a consultant to help with their PWS. - Flint has formed a Technical Advisory Committee (TAC) to help with their PWS; Dr. Michael Wright (ORD toxicologist) is EPA’s representative. - The Technical Advisory Committee met last week for the first time. Paul Joice said that he was at the TAC meeting but did not participate as there were not enough seats for the large crowd. He heard that it was a good meeting. Paul said that he would like Dr. Wright to be able to make a public statement about health effects. The public notice for the TTHM violations say that sensitive subpopulations should consult their physicians but the physicians don’t have any info on TTHMs. Paul had questions about Flint’s drinking water: 1) What are the health effects of TTHMs and what level of exposure is a concern? 2) What message should be provided on TTHMs? 3) What can be done about Flint’s aging infrastructure and falling population base? 4) What about citizen complaints about their water looking funny, tasting funny, and smelling funny? Paul said that having Dr. Wright on the TAC will help resolve Q1 and Q2. Paul said on Q4, that he lives in the city and his water looks and tastes fine. | said that taste and odor issues could be the result of the flushing that Flint had done due to the bacteria and TTHM problems. Flushing can stir up sediment in the pipes. | said that there have also been complaints about rashes from using the water but that this may not be solely due to high TTHM levels. It could be because of increased chlorine in the water, changes in water chemistry (pH, hardness, etc.). It would take some investigative work to determine what part of the distribution system is having these problems and would need additional health/medical data to try to figure out a cause. Paul said that many of the people who complained did not want to give out their home addresses. On Q3, | said that many systems across the country have aging infrastructure and while there is SRF monies available, this money does not cover the needs out there. Paul asked about regionalization. Eric Burneson acknowledged that there are economies of scale with regionalization but the benefits are realized more for smaller systems than ones the size of Flint. We could not generalize whether regionalization was a good idea for Flint and other communities in Genessee County because it is a very site specific issue. Paul said that our conference call helped him under the Flint situation better. Tom Poy Chief, Ground Water and Drinking Water Branch USEPA - Region 5 (312) 886-5991 xxxEND_PAGE:deq21_b561_1590_1592_3
