Attached for your review is EBL water protocol with revisions made in response to EPA comments 2 through 8. Regarding comment #1: some of the issues raised by EPA will be addressed by the GCHD nurse case managers (e.g., filter maintenance). Other issues are difficult to address in the context of the protocol. For example, the timing of exposure relative to an elevated blood test and subsequent EBL investigation will vary between children and will be difficult to identify in most cases. In addition, it’s unlikely that most Flint homes would have been using a water filter prior to Oct 1, 2015. Given the limitations and the need to identify and abate relevant exposures as quickly as possible, the best we can do is measure current lead levels in unfiltered tap water as a proxy for past exposures. | need to share this with our contractors and oversight staff so the changes can be implemented. Please let me know ASAP if you have concerns. Linda

Date: Monday, December 07, 2015 10:11:16 AM Thanks Jim. | think we can make the recommended changes to the sampling steps, provided DEQ is willing to and can provide wide-mouth bottles. The response to comment #1 is somewhat complex and will vary depending on when an EBLL was reported. Does DEQ plan to respond or should HHS take the lead? Linda

Revised. SHe the note on page two regarding stagnation times greater than 24 hours. i would orefar to use L& hours, fut the EPA notes recommended 24 hours sol went with that. Please int rne know if you have any other comments. Jirn ~ f think this can be shared with EPA aven if staff have further comments.

This is what we got back from EPA on the protecol being used by HHS

Updated lead and copper sampling instructions for residents/customers. We have modified our instructions to address concerns raised. We have not vetted this through any district staff to see if they have any other recommendations. This could be done concurrently with EPA’s review. xxxEND_PAGE:deq15_b768_2732_2732_1

FYi- revised version. I'm meeting at 2pm with Kory, Michelle and Jennifer,

Just in...

| have some suggested changes. | used track changes, there is a comment on the last page regarding the use of “not detected” where earlier in the document we say “non detect”... think we should pick a way and be consistent. After these small changes, and George’s approval on content, | think we can forward to Lisa in OEA to put in report format. xxxEND_PAGE:deq21_b358_1029_1029_1
