11/30/2010	If possible, would somebody from FO5 conduct a site inspection (or full sanitary survey) of the NEW Treatment Plant at Saylorville Lake for DMWW before the middle of December 2010? Per Chris Jones, the NEW Treatment Plant at Saylorville may be up and running in the middle of December 2010. If possible, could FO5 coordinate the inspection or SS with Marie Leat and Anne Lynam of WSO so we can learn about the new plant? Thanks!	MARIE LEAT

6/16/2011	A complete sanitary survey was conducted.	JANET GASTINEAU

We need to review all of their calculations and SCADA programming to come up with how pressure loss experienced during daily testing correlates to particle removal. I don’t know that we need to be on site for this, but it will take some sending back and forth of data and air integrity testing results. No one here has experience with actually doing this, as I said, so it may take us a while to figure out exactly what we need. I think Taroon and I will work on this together so that we both have the experience of doing it since we’ve got several other membrane plants in the works right now. ________________________________________ From: Gastineau, Janet [DNR] Sent: Tuesday, November 30, 2010 1:37 PM To: Bunton, Jennifer [DNR]; Leat, Marie [DNR] Cc: Lynam, Anne [DNR]; Grapp, Shelli [DNR]; Petersen, Ted [DNR] Subject: RE: Questions about membrane system at the Saylorville Lake TP for Des Moines Water Works -- PWSID 7727031 Who does this evaluation? Marie sent a work request asking for a sanitary survey. I am happy to wait if this is evaluation is something engineering wants to do in conjunction with issuing a construction permit and accomplish the same thing for the operations permit.

11/30/2010	From: Bunton, Jennifer [DNR] Sent: Tuesday, November 30, 2010 1:27 PM To: Leat, Marie [DNR] Cc: Lynam, Anne [DNR]; Gastineau, Janet [DNR]; Grapp, Shelli [DNR] Subject: RE: Questions about membrane system at the Saylorville Lake TP for Des Moines Water Works -- PWSID 7727031 We will need to do an evaluation of the plant before we can assign the testing parameters. Roy went over how to do it before he left, but it’s probably going to take a bit of time to actually go through it with them. The appendix will probably look similar to Keokuk’s but will not be the same. On another note, we have never issued a construction permit for this plant. This has dragged on for about a year and a half now and they have not been providing the last bits of information I need to finish it up. I spoke with their engineer again two or three weeks ago when Anne initially asked about this and let him know what we still need, and he has not responded. We should definitely not be issuing any operating permits for this plant until construction permitting is done, and even then, we will need to go through the membrane stuff with them. That may take a while, so maybe once the construction permit is done, you could issue them an operating permit for everything but the membrane stuff while we get it worked out, hopefully fairly soon, or not issue anything until we get it figured out.

Do you know if the membrane system at Saylorville is similar to Keokuk’s (attached is the permit appendix for Keokuk)? It sounds like DMWW wants to start using the Saylorville plant in a couple weeks (per Chris Jones). Thanks,	JANET GASTINEAU
