RE_ South Y PCE - LBWC Request for Information for Alternative 1From:Ivo Bergsohn To:"Jennifer Lau"; Jennifer Lukins Cc:Sachi Itagaki; Grace Chen Subject:RE: South Y PCE - LBWC Request for Information for Alternative 1 Date:Tuesday, July 2, 2019 5:11:27 PM Attachments:image002.pngimage003.jpgimage004.jpgimage005.jpg Hi Jennifer- District logs well production on a daily basis. If that is what you need, that shouldn’t be a problem. If you are looking for demands on the hour, that would take more work for possible recovery through SCADA Historian. Caution- July 4 is not necessarily indicative of peak-peak water demands; max days are often a couple days before or after the july 4th holidays to meet summer demands and replenish stored water. I’d have to go back and take a look at the historical data, but as I recall MDDs typically occur on days other than 7/4. -Ivo From: Jennifer Lau [mailto:JenniferLau@kennedyjenks.com] Sent: Tuesday, July 02, 2019 4:07 PMTo: Jennifer LukinsCc: Sachi Itagaki; Grace Chen; Ivo BergsohnSubject: RE: South Y PCE - LBWC Request for Information for Alternative 1 Hi Jenn, We in KJ were working through the baseline alternative, and we realized with the Fourth of July weekend approaching, this would be a great time to gather pumping data for each of the wells to see how they operate during peak demand. Is this something you could also provide? We would also be interested in other data that could inform the diurnal demand/well pumping curves for the system. Please let us know if you have any questions! Thanks again!

Based on TAC Meeting 5 and our current work to develop the Baseline (Current Treatment/Operations) Alternative 1, we have developed a list of information we’d like to ask for the Lukins Brothers Operations and Maintenance. We set up a OneDrive for you to upload information: https://kjcnet- my.sharepoint.com/:f:/g/personal/jenniferlau_kennedyjenks_com/Em9HabWCFMRAkhC- zqtf76YBnvd6Mi6mmq3wtwN4aVZrvw?e=b60fX0 Can we also schedule a time to go through this list, and answer any questions you have about the request? Let us know your availability by filling out this Doodle Poll: https://doodle.com/poll/7wds2tubsd3mqvqn 1. Can you provide the grant application for the LBWC 5 GAC? 2. If not already in the LBWC 5 GAC grant application, can you provide the following information: a. How much chlorine is being used annually per well? i. How much does this cost annually per well? b. What was the average annual cost of labor for Water Company O&M staff? i. Can you break this down by well/facility? On average how much time throughout the year does staff spend on: 1. Well 1 2. Well 5 (historically) 3. Water System overall b. What is the average hourly rate for all Water Company O&M staff? c. How much energy was used at Well 1 and Well 5 historically? i. If you have historical data, we can calculate an average ii. What is the cost of energy for each well e. What is the cost of water purchased from STPUD? f. Please tell us if you have other O&M costs related to the Water Company g. Can you provide us with hourly or daily water consumption or production data for each well that can help us understand how often each well runs? h. Can you provide us with any recent pipeline or well construction project/maintenance costs or engineering reports that may help us in estimating costs for the Feasibility Study Alternatives? Thank you, and please let us know if you have any questions.
