CES Contract Revisions: Not discussed. 2. Wastewater Plant Operations a. Monthly Report: The plant is running in compliance with all performance parameters in March. Suez responded to eleven (11) grinder pump service calls, all but one for Interon pumps. The plant was shut down 3/12/16 due to low air pressure for approximately 90 minutes. Suez re- placed a faulty separator filter from inventory. National Grid completed its energy audit. The main building has light fixtures circuited through oc- cupancy sensors, and 8-12 lights don't work now, but Suez noted that there is sufficient light levels for safe working environment. Unfortunately, there is not much cost savings opportunity in replac- ing so few light fixtures. Chairman Baldwin suggested that when replaced, LED fixtures should be provided. Mr. Sawchuk recommended that Suez investigate a demand response system for an electrical load shedding program to collect rebates. The grit screw was squeaking and annoying nearby neighbors once again. Suez shut it off 3/29/16. A week later, it was turned back on and for 45 minutes it didn't squeak, but Suez shut it off when they left for the day in case it squeaked during the night. It's been running everyday all day for the past (2)weeks without a noise. Mr. Coughlin contacted Lakeside,the manufacturer, and with their help discovered there was no obvious reason for the noise. It was determined that a piece of de- bris could have wedged in the screws and came out on its own.

Missing Water Meters: Chairman Baldwin stated that several properties have been connected to the collection system but have not been billed for service provided. There are no water meters installed at 189 Hull Street, 191 Hull Street, or 268 Jerusalem Road so water consumption cannot be determined as a basis for sewer usage charges. Chairman Baldwin noted that 177 Hull Street doesn't have a meter either, but they are billed an estimated charge likely greater than actual flow. Chairman Baldwin directed the Water Department to bill these properties for the fourth quarter based on estimated flow. The Board agreed that these properties should be billed for the fourth quarter, but that it was important to notify the residents prior to receiving a bill. They should also be advised of the option to install a meter in lieu of usage being estimated. The Board agreed that these properties should be billed for usage in arrears, but was unclear on how far back the Board could go legally? Mr. Sawchuk recommended that the property owners be asked to come before the Board to discuss the matter. Chairman Baldwin will ask Town Counsel for its opinion on the matter. b. 1-3 Brook Street- Both the inside and outside was cleaned out.
