RE: FOIA 0510-16 SECOND NOTICE

Your right, When ft reviewed the packet of materials that you were sent, | thought that page 9 was from the community water supply program. They looked really sirnilar. The document on page 9 of the packet that you received is the instructions that were used by the Genesee County Health Department to collect the screening sarnpies taken in October at schools in the City of Flint. This document was prepared specifically for that purpose and, to my knowledge, has not been used for any other purpose. Liane 4. Shekter Smith, PLE.

Ms. Lambrinidou — As you noted, “The second document (page 9) is the instructions document that we provide to community water systems to assist them with their lead and copper compliance xxxEND_PAGE:deq04_b431_4709_4715_1 monitoring.” This document is not addressed specifically to schools. We did not intend to imply that these instructions are for sampling at schools. However, it is possible that there could be a community water system that does not have adequate Tier 1 sites available or accessible and the potential exists that a community water supply could utilize a school in their sampling pool. We wanted to be sure to include all of our lead and copper sampling protocols as part of our response to your FOIA request in an effort to be complete. My apologies if this caused confusion. Liane J.

Re: FOIA 0510-16 SECOND NOTICE

Hello Ms. Shekter Smith, Thanks for your response. | am familiar with the LCR and agree with your notes below. However, my question pertains to the sampling protocol on p. 9 of the packet | received. The document is titled "Drinking Water Lead & Copper Sampling Instructions" and according to Tracy Jo's email below this is "the instructions document that [MDEQ] provide[s] to community water systems to assist them with their lead and copper compliance monitoring." This document is addressed specifically to schools, it asks for just one sample, and it seems to serve water utility LCR compliance monitoring requirements. Hence my question about whether community water systems in MI include school samples in LCR compliance calculations. If someone could help shed light on this, | would appreciate it.

RE: FOIA 0510-16 SECOND NOTICE

Ms. Lambrinidou : To follow up regarding your inquiry: The first document (pages 1 — 8) is the draft working document that we created to sample schools within the City of Flint that are on the city’s water system. The draft provided as part of the FOIA is dated November 6, 2015. That working draft continues to be updated. The second document (page 9) is the instructions document that we provide to community water systems to assist them with their lead and copper compliance monitoring. | believe this document was created in 2011 and was in use until this week. A revised sampling instructions document is posted on our website at http://www. 2015_508290_7.pdf. The third and fourth documents are currently in use by our Noncommunity water supply program. Both documents are dated at the bottom of the page. One has a 9/2013 date and the other has a 10/2012 date. These would be the dates that the document was created and/or revised. Hope this is helpful.

Sampling Location (Sampling siting plan approved by local health department in sanitary survey) Laboratory Name —. Phone Lead/Copper — General Information Lead fs a common metal found throughout the environment in lead-based paint, air, soil, household dust, food and water. It builds up in the body over many years and may result in damage to the brain, red blood cells and kidneys. Lead enters. drinking water primarily as a resuit of corrosion, or wearing away of materials containing lead in the water distribution system. These materials include lead-based solder used to join copper pipes, brass and lead piping. The concentration of lead in drinking water may be a function of numerous factors related to the presence of lead, water chemistry, temperature, pH, system hydraulics, usage, etc., and can vary over time. The presence of copper in drinking water fs also primarily a result of corrosion. Acute exposure to copper can result in nausea and diarrhea. The US EPA has established an action level for lead of 0.015 milligrams per liter (mg/l) and 1.3 milligrams per IIter (mg/l) for copper. for public water supplies, SAMPLING PROTOCOL Obtain sample containers and analysis from a laboratory certified by the DEQ for lead/copper analysis. > Collect first draw samples. (Water has stood motionless in the piping for at least 6 hours.) Do not sample after weekends, holidays or extended periods of stagnation. Do not flush the sample tap before sample collection. > Collect samples where water is drawn primarily for drinking. Sample drinking fountains or kitchen/break room faucets if they are used routinely to obtain water for consumption. Do not sample from slop sinks, hose bibbs, etc. ones that represent the water distribution system, i.e. one in each building wing or on each floor. Or, you can collect more than.the minimum number of samples.

(f you have a only a few buildings, split the samples among them as best you can according to where the water is being consumed. ff you have fewer drinking water fixtures than the chart requires, sample the ones you have and note on the sample log sheet you have sampled all drinking water fixtures. Properly identify the sample location on the.lab slip and include the water supply serial number (WSSN) on the lab sample forms to properly identify the samples, otherwise, you may not be credited as having sampled. > Be sure to request the proper lab analysis or test code for lead/copper and place the forms with the bottles.

If you exceed an action level, you must: « Notify the local health department within 24 hours or the next business day. e Notify the public (consumers) of the lead. action level exceedance as instructed by the health department and take steps to minimize exposure (shutting off fountain, or flushing) as instructed. * Additional actions such as sampling the source water for fead/copper and investigating possible sources of lead in the distribution system should be discussed with the local health department. vvvwv Vv Within 6 months of the end of the monitoring period in which the action level was exceeded, the facility will need to submit a proposal to conduct a “treatment study” or install “corrosion control treatment.” xxxEND_PAGE:deq27_b236_1088_1093_4 > Submit thé samples to the laboratory for analysis, and record the results on the sample recerd log provided by the MDEQ. > Calculate the 90" percentile using the directions on the log sheet, or submit your sample results to the local health department's noncommunity staff person for calculating the 90" percentile, > Whether or not you do the calculations of the 90" percentile yourself, you are required to submit the results to the local health department noncommunity staff person. Action levels of 0.015 mg/liter (ppm) far lead and 1.3 mg/liter (ppm) for co; copper were established in 1991. If the 90" percentile result exceeds either level, the water supply is required to initiate an investigation by: Q Contacting the local health department for further instructions Q Sampling all other drinking water taps not previously sampled Sampling the. source water Providing public education on the lead exceedance to the population exposed. A copper exceedance does not require public notice at this time. Q Qa Corrective measures for action level exceedances may include replacement of fixtures, piping or service lines. If the contaminant level still cannot be reduced below the action level through implementation-of these measures, the water supply will need to conduct a treatment study to investigate whether the installation of corrosion control technology may be necessary.

OF ENVIRONMENTAL QUALITY xxxEND_PAGE:deq27_b236_1088_1093_5 In 1974, out of concern for the quality of the water we drink, Congress passed the Safe Drinking Water Act. This Act gave the U.S. Environmental Protection Agency (EPA) responsibility for establishing and enforcing drinking water quality standards nationwide. The Michigan Safe Drinking Water Act (Act 399) was enacted in 1976 and enables the Michigan Department of Environmental Quality (MDEQ) to maintain primacy (state authority) over the drinking water program in our’ State. This Act regulates both community and noncommunity water supplies. Noncommunity water supplies (NCWS) are of two different types: > A transient NCWS is one that serves water to 25 or more different people each day for at least 60 days out of the year. Examples include restaurants, convenience stores, campgrounds, etc. > Anontransient NCWS serve the same 25 people each day for six months of the year, such as a school, factory, office building, etc. The Safe Drinking Water Act contains language regarding the requirements for nontransient, NCWS’ built prior to 1987 to test for lead and copper. The Federal lead and copper regulations were revised in 1998. These revisions went into effect on April 11, 2000, requiring that ALL NCWS to test for lead and copper. The rule changes have been implemented in Michigan as part of the primacy agreement. The sampling frequency is established below in Table 1: # Samples after Reduction* Student/Employee # Sampies/ ati -S.months 501 to 3,300. 20 10 101 to 500 2» 5 <101 5 * After 2 six month sets below the action level a reduction to annual testing is allowed _- FREQUENTLY ASKED QUESTIONS Why be concerned about lead or copper? Lead is a common metal found throughout the environment in lead-based paint, air, soil, household dust, food and water. /t builds up in the body over many years and may result in damage to the brain, red blood cells and kidneys. Lead enters drinking water primarily as a result of corrosion, or wearing away of materials containing lead in the water distribution system, such as lead service lines and lead solder. The presence of copper in drinking water is also primarily a result of corrosion. Acute exposure to copper can result in nausea and diarrhea. / have never had to sample before. Why do! have to now? The revised rule requires that all of the nontransient NCWS must test for lead and copper. It has been shown that some fixtures, even though they were labeled "lead-free" have released small amounts of lead when exposed to water with corrosive or acidic qualities. Copper is still | commonly used in plumbing fixtures and piping, and these water quality factors may cause copper to be released into the drinking water. / only have two drinking water fountains in my building? Do | still have to take the required number of samples? If you have fewer drinking water fixtures than the chart requires, sample the ones you have and note on the sample log sheet you have sampled all drinking water fixtures. We operate a large facility with multiple buildings and numerous drinking water fixtures, How many and where to do we sample from? Sample the drinking water fixtures in the building up to the chart number based on the population of your facility. For instance, if your building has eight drinking water fixtures, and you are required to take five samples, sample only five of the fixtures. If you have more than the chart number of drinking water fixtures, select ones that represent the water distribution system, i.e. one in each building wing or on each floor. For large facilities colléct at least one sample per building until you get the number of samples required in Table 1. Or, you can collect more than the minimum number of samples. If you have only a few buildings, split the samples among them as best you can according to where the water is being consumed. SAMPLING PROTOCOL : >» Obtain sample containers and analysis

RE: question about optimal WQP ranges for Flint's water

Dr, Lamibrinidou, Yen sarry for the delay in my respanse. As some of your questions relate more to statewide program iraplementation | have requested assistance with the response from staff within aur central program office. However, these staff were attending and participating in an offsite (American Water Works Association Conference Michigan Section} canference last week. G Michigan has implemented an EPA approved modified consecutive system annraach to lead and copper monitoring where a wholesale water supply sells water to other cormmunity water systems. in addition, while water quality parameter (WGP) monitoring occurs at both the water treatrnent plant and in the cornbined distribution system, a WOQP range is only required to be established at the water treatment plant tap after the systern has demonstrated optimized corrosion control treatment (OCCT). Thus when the City of Flint was a customer of the Detroit Water and Sewerage Department (DW5B}, the City of Flint participated in WOP monitoring of its distribution system, but ranges ware established only for the OCCT at DWSD reatmert plants. The attached letter from our Department established the minimurn levels for pH and phosphate dosage in 2000. As the City of Flint water treatrnent plant has not yet installed such treatment or been given the designation of OCCT hese plant tap values have not been established. However, the City of Flint WTP has continued to maintain the minimurn pH value requirement previously established for DWSD As noted in your Working Group Report to the NDWAC, “Corrosion Control Treatment (CCT) involves the addition of chemicals (e.g. orthophosphates or silicate} to create a barrier between the pipes and the drinking water, or to modify drinking water chemistry {such as pH and hardness} to inhibit the potential for corrosion.” Should you consider the Flint WTP softening process te be OCCT, then the City already continues to comply with the OCCT requirements as the City of Hint has never hac 10% or more of compliance tap samples exceed the 15 ppb action level. Even prior to DWSD’s established OCCT the City of Flint lead compliance monitoring has never exceeded the 15 ppb action level, f you have additional questions we would appreciate having therm routed through the NDWAC and your Working Group.

Re: question about optimal WQP ranges for Flint's water

Dear Mr. Busch, Thank you for your quick response. | appreciate the information at, | am sure, a very busy time for you and MDEQ. Could you please help me understand the following? When you say that all previous optimal water quality parameter ranges would have been established for the Detroit water utility (not for the City of Flint), do you mean that MDEQ never set optimal water quality parameter ranges specifically for Flint before Flint's switch to Flint River water? It is my impression, please correct me if I'm wrong, that under the LCR, all large systems -- whether they are consecutive or not -- must have optimal water quality parameter ranges designated by states specifically for them (at the time when these systems are deemed to have optimized their treatment). Is there language in the LCR | am missing that allows a utility not to have optimal quality parameter ranges established specifically for it? My second question is this: If the City of Flint had no optimal water quality parameter ranges established specifically for it in the past, how did it achieve LCR compliance? Isn't it the case that utility-specific optimal water quality parameter ranges (and maintenance of these ranges) are required for all large systems to avoid an LCR violation? | would appreciate your assistance on this matter, as it will shed light on an issue that seems to be very important for EPA's assessment of and upcoming revisions to the LCR.
