Thank you, Jon On Thu, Mar 16, 2023 at 8:55?AM Elana Becker <elana.becker@bayer.com> wrote: Hi Jon, I have forwarded these questions on to our team and will respond with answers as soon as I hear back. Thank you, Elana Becker From: Ryk, Jon <jon.ryk@dnr.iowa.gov> Sent: Wednesday, March 15, 2023 10:24 AM To: Elana Becker <elana.becker@bayer.com> Subject: Follow up questions for Sanitary Survey Elana, I am doing some preliminary work on the sanitary survey report and have the following questions for you and the team there: 1. Do you know the frequency of granular activated carbon (GAC) regeneration or replacement for the GAC filters at the facility? 2. You indicated that there are booster pumps in the tall units (A-Unit, potable shack). Are the booster pumps equipped with a backflow protection device and automatic shutoffs or pressure controllers to maintain at least 20 psi in the suction line under all conditions? 3. Regarding auxiliary power, the last sanitary survey indicated that the system has two independent power sources. Is that still the case? Also, I received the email message from Alex the yesterday regarding ordering the 56% ammonium hydroxide solution for the chlorine room. He mentioned it would likely arrive today. Thank you, Jon JON RYK
