Engineers report high ammonia at Paradise Township plant as board approves $26,960 change order
Summary
Rettew Associates told the Paradise Township Sewer Authority on June 2 that the wastewater treatment plant is experiencing high ammonia levels; the board unanimously approved Change Order #3 to Pumping Solutions, Inc. for $26,960.60 for motor-control and pump-starter work. Contracts #2 and #3 were noted as substantially complete.
Abraham King and Aaron Dewald of consulting firm Rettew Associates reported on June 2 that the Paradise Township Waste Water Treatment Plant continues to experience elevated ammonia levels and that contractor Lobar, Inc. is working through a list of items intended to reach substantial completion. The engineers also told the board that the HVAC for the control room has been installed and that Contracts #2 and #3 have reached substantial completion.
To address immediate control-room and pumping needs, the board approved Change Order #3 on Contract #2, payable to Pumping Solutions, Inc., in the amount of $26,960.60. The change order covers modifications to the motor control center and the installation of a well pump starter and additional receptacles. The motion to approve the change order was made by Dave Bowman and seconded by Brian Groff; the motion carried unanimously.
Why it matters: high ammonia can affect permit compliance and downstream permit-holders; the board’s actions and contractor work aim to bring the plant into compliance and finalize construction deliverables. Rettew told the board it will continue to monitor plant performance and report progress.
Board members and consultants also discussed an outstanding vendor claim (recorded in the minutes as from "Violia") for about $16,000 for non-commissioning support hours; Rettew has not made a determination and will present a separate report to the board at a future meeting.
The board did not set a new public hearing or vote on any change to plant operation at this meeting; Rettew will continue to update the authority as the contractor remedies the outstanding items.
