Phosphate Calculations - Revision 4.pdf Hi Mike, | just wanted to follow up on the email below and get your estimation on when the permit will be issued. Are you requiring any additional data before a decision can be made? The calculation that we developed meets with the requirement of the feed rates as agreed to between your office and the EPA based on the email from Stephen Busch to the EPA on November 22, 2015. The pumps were resized to handle the anticipated Max feed rates requested. We are assuming that since we are using the chemical used by DWSD or corrosion control, we are not required to go thru a study phase. Additionally, during our review of the email trail with EPA, we noticed that the EPA did recommend that Jar Testing be done to evaluate the impact of the orthophosphate dose on turbidity of the DWSD water. Stephen has also noted that a treatability study will need to be conducted on the KWA water in conjunction with the Flint WTP processes to optimize the corrosion control treatment needed before use in the system. Does the permit to be issued going to highlight more specific requirements on the duration(s}), method{s) and reporting needed for each of the testing required before implementation is allowed into the system? Your assistance and feedback are greatly appreciated to make sure that our timeline for the introduction of the initial corrosion control into the DWSD water and its future implementation into the KWA Raw feed can be accurately depicted in our discussions with the City and KWA, Thank you very much for your continued support.

ACCIDENTAL RELEASE MEASURES Personal precautions Avoid unnecessary exposure and remove all material from eyes, skin and clothing. Do not ingest or inhale mists of phosphoric acid. Environmental precautions Small quantities: Avoid discharge into the environment Large quantities: May cause pollution. Avoid discharge into the environment. Note methods for cleaning up in the next section. Methods for cleaning up Contain large spills with dikes and transfer the material to appropriate containers for reclamation or disposal. Absorb remaining material or small spills with an inert material and then place in a chemical waste container. Neutralize washings with a base such as soda ash or lime. Flush residual spill area with large amounts of water. Refer to Section 13 for disposal information and Sections 14 and 15 for reportable quantity information. 7. HANDLING AND STORAGE Handling Do not get in eyes, on skin, or on clothing. Keep container closed. Avoid breathing mist or vapor. Use only with adequate ventilation. Do not taste or swallow. Wash thoroughly after handling. Engineering measures Provide natural or mechanical ventilation to minimize exposure. The use of focal mechanical exhaust ventilation is preferred at sources of air contamination such as open process equipment. Consult National Fire Protection Association (NFPA) Standard 91 for design of exhaust systems. Transfer product from drums to process in closed system (hermetically) and if not possible use effective local exhaust ventilation. Empty drums as thoroughly as possible to facilitate disposal. For bulk transfer, purge lines with nitrogen to remove residual liquid before disconnect. When unloading bulk vehicles, personnel should wear chemical goggles and rubber or neoprene gloves. All fittings should be properly secured prior to energizing unloading system. Care should be taken to avoid acid contact when disconnecting lines/hoses after unloading. For bulk storage type 316L stainless is recommended. Glass, polyethylene and FRP (depending on resin used) are satisfactory, steel, aluminum and type 304 stainless are not recommended because of rapid or potential corrosion. Vessels should be vented and operated at ambient conditions. Maintenance heat (hot water preferred) may be used to prevent freezing. Dike area around storage tank with sufficient volume to hold entire tank contents. Storage Store in plastic, rubber-lined, or 316L stainless steel tanks designed for Phosphoric Acid, Store drums away from heat and out of direct sunlight. Store in a well-ventilated dry area away from alkalis and most metals. Store above freezing point. Contact with reactive metals, i.e. mild steel and aluminum may generate hydrogen that may form and explosive mixture in storage vessels. xxxEND_PAGE:deq03_b286_0445_0867_404 ICL Performance Products LP Safety Data Sheet Material: Phosphoric Acid (35%-95%) Page 4 of 7 Reference No.: AST 10046 May 19, 2015 For tank inspection, follow manufacturer's recommended safety guidelines (ex. temperature, etc.).

Hi Mike, Please see attached plans for the Corrosion Control Plan for the City of Flint. | will have the official submittal package to you tomorrow afternoon after | get Brent or Mike’s signature on the permit application. | will call you when | get back in Lansing to drop the package. Is three sets of full size plans adequate? Would you like some half size plans? Let me know. Basis of Design ‘ Given that Flint will require lead and copper corrosion control and given that Detroit utilizes orthophosphate for their corrosion control methodology, and that Flint will be receiving Detroit water for the immediate future, orthophosphate ~ is the appropriate corrosion control methodology for Flint. A dosage of 0.8 mg/l as PO, has been recommended for the Detroit water. Numerous utilities utilizing Lake Michigan water have a target dosage of 0. 9 mg/l as PO,. Therefore, a target dosage in the range of 0.8 to 0.9 mg/l appears apptoptiates It is expected that, at least initially, there will be a significant PO, demand in the system. This will require a significantly higher dosage until this demand is satisfied and the target residual can be maintained. We are therefore designing for capability of a maximum dosage of 1.5 mg/l. xxxEND_PAGE:deq28_b107_0427_0429_2 t The arriving Detroit water will likely have some residual PO, when it arrives at Flint. It has been reported that this residual will be approximately 0.4 mg/I. The system must therefore be capable of a minimum dosage of 0.4 mg/l. Based upon the usage of 75% Phosphoric Acid and a flow range of 4 MGD to 25 MGD, with an average day of 16 MGD, ‘the expected feed rate will be 1.35 to 32 gpd. Average Phosphoric Acid feed is expected to be 10.8 gpd, requiring 30 days storage of 325 gal. 8 Orthophosphate will need to be applied at two locations. Detroit water will enter the Flint system at Control Station CS2, and supplementary phosphate will be applied there. However, on occasion some incoming water may need to be diverted to the Dort Reservoir, bypassing CS2. This water would theh be introduced to the system through High Service Pump Station PS4 and phosphate would be introduced at this location. Please let me know if the information is adequate or you require additional information. Thanks.

Samir, Three full sets if u can....otherwise half size set will suffice Sent from my iPhone

Samir, We are looking to fast track the corrosion control to basically a 24/7 effort. 1 believe that the Director of the MDEQ will be support fast as possible I will work internally to complete all contractual needs under an emergency basis and will look to talk with you very soon to confin that may be required from the City. Thank you,

Samir, The GAC addition and sand filter media replacement for the filters at the Flint WTP is approved. Construction Permit # W 151055 issued on July 14, 2015 validates the approval. A hard copy of the permit along with a set of approved plans and specifications will be mailed out today and you should receive the set within the next few days. This e-mail; however, acknowledges issuance of the DEQ construction permit; thus construction work pertaining to this project may proceed. If you have any further questions, please don’t hesitate to contact me. Michael Prysby, P.E. District Engineer Office of Drinking Water and Municipal Assistance 517 290-8817

Hi Mike, As per our phone conversation, Calgon is pumping the wet sand into a truck with screened valves in the back that allows the water to drain out while keeping the sand in the truck. The removed materials is trucked to a landfill for disposal. The new sand comes in large bags that is dumped into a hopper and pumped back into the filter after water is added to the system. | have included photos of the sand being pumped out into the truck for your review. We also like to have the plant facility remain at 36 MGD and not change to 30 MGD even though we do not expect the City demands to get that high. Let me know if you need anything else. Samir F.

Samir, We are not involved with the selection of a contractor for the upcoming work. The described approach is agreeable provided that the design, materials used, and method of installation is approved and permitted by our office in advance of the city making a financial commitment towards the system alteration. Please reference Sec. 325.1004 (6) of the Michigan Safe Drinking Water Act for further discussion of the permitting requirements for alteration of the water system. As we discussed, our office will review the design and, following our approval, issue a construction permit in a timely manner. If you have any further questions, feel free to contact me.

Hi Mike, As per our phone conversation, LAN has been working with the City to implement the recommendation from Veolia with regard to the conversion of the 12 filters at the plant by replacing the 18” Anthracite with new GAC Media. Due to the time frame limitation, We have discussed with the City that sole sourcing the GAC purchase and installation may be the only chance for us to accomplish the work on time as the system will need to be in place by early July in order to give the City 5-7 weeks of treatment time with the new media before the August sampling. The City is looking for us to provide a turn-key delivery method in order to insure that we can acquire a vendor while performing the design and going thru your office for permitting. Let us know if you agree with the approach or if you recommend a different method. Your prompt response is greatly appreciated. Samir F. Matta Senior Project Manager Prekwond, Andrews &Newnam;,Inc.

Duffy, We heard back from Innovyze. The model file got corrupted, but they are walking us through a fix. We are documenting the process so we'll know what do do if it happens in the future. We expect to have fixed this afternoon and have the maps to you thereafter. Thank you, Melissa Sent from my iPhone
