Work to remove the old mercury filter at the Corbin City Utilities’ Wastewater Treatment Plant will cost a little more. Which is why the City Utilities Commission board approved two change orders for the project during their regular meeting Tuesday afternoon.
“Getting rid of the visible mercury will cost $80,000 more. The total project will run about $250,000, and will be paid for with CUC funds,” General Manager Ron Herd said.
On July 31, Perdue Environmental Contracting Company, Inc. was the apparent low bidder for removing the mercury at the plant with a base bid of $58,201.45 and an alternate bid of $19,356.75.
At the time, the consultant prepared a bid tab with worst case and likely-to-occur costs, using the base bid and unit prices in the bid. The worst case scenario unit pricing was listed at $795,385.45, while the more likely scenario unit pricing was listed at $94,041.11. Also at the time, Herd said the final cost wouldn’t be known until all the mercury is taken out.
He added bids for the 2013 Chemical Requirements were received until 2 p.m. on Nov. 1, then publicly opened and read aloud. Brenntag was the apparent low bidder in seven of the nine categories bid on.
Brenntag had the low bid on Liquid Chlorine at $0.194 per pound, Sulphur Dioxide at $0.530 per pound, Sodium Chlorite at $2.020 per pound, Fluorosilicic Acid at $0.309 per pound, Liquid Copper Sulfate at $16.200 per gallon, Tote Caustic Soda Liquid at $0.212 per pound, and Liquid Sodium Thiosulfate at$0.300 per pound.
Univar had the low bid in two categories — Potassium Permanganate at $2.950 per pound and Bulk Caustic Soda Liquid at $0.230 per pound.
Bids were also received by Cedarchem, C. I. Thornburg and Key Chemical, while GEO Specialty made no bids.
Among other actions, board members renewed CUC’s health insurance quotes through Anthem Blue Cross-Blue Shield, with the average rates going up 5.7 percent. Also approved was an engagement letter authorizing Marr, Miller & Myers, PSC to perform the yearly audit for the fiscal year ending on Dec. 31. And CUC will provide electricity for the lighting at Colonel Sanders Park at the corner of North Main and Monroe Streets downtown, after a request from the City of Corbin. The park, named after Colonel Harland Sanders of Kentucky Fried Chicken fame, is scheduled to be open next August.
Herd noted the City Utilities Commission office on the Cumberland Falls Highway would be closed next Thursday and Friday, Nov. 22-23 for the Thanksgiving holiday, and will reopen for business on Monday, Nov. 26.
