Under the Ashland Municipal Code, if there are no exemptions or special circumstances, a formal competitive selection process is required to enter into a public contract for goods and services greater than $50,000.
A Competitive Sealed Bid (Invitation to Bid) is the sourcing method for this public contract.
The City of Ashland's Wastewater Treatment Plant operates under a National Pollutant Discharge Elimination System (NPDES) Permit, issued by the Department of Environmental Quality (DEQ). Schedule A of this permit outlines our discharge limitations for CBOD, TSS, Ammonia, Total Phosphorus (TP), E. coli, pH, Dissolved Oxygen and temperature. Most of the chemicals listed are used to assist us in meeting the Total Phosphorus requirement. The City is allowed to discharge an average of 1.6 lbs/day from May 1st through November 30th each year. Aluminum Sulfate is used to assist in precipitating out the TP as much as possible after the biological process; however, the City cannot fully meet the established TP limit through the secondary process alone. The City therefore needs to remove the remainder through a tertiary treatment process (membrane filtration). Most of the other chemicals listed (Sodium Hypochlorite, Sodium Bisulfite, Sodium Hydroxide and Citric Acid are used in the membrane filtration system.
Calcium Hypochlorite is used throughout other areas of the plant for disinfection and/or cleaning.
The City of Ashland requires chemicals that will assist in meeting the strict limits of the NPDES permit.
The goal of the Wastewater Department is to retain and secure specific prices for chemicals used at the Wastewater Treatment Plant. The contract(s) will be issued for the annual usage period - March through November - with the option to renew each contract for one additional year.
The Invitation to Bid was sent to five (5) potential suppliers and four (4) suppliers responded to the bid. The bid submitted by Univar, USA provided the lowest responsive and responsible bids on chemicals #1, 3, 4, 5 and 7. The bid submitted by Cascade Columbia provided the lowest responsive and responsible bids on chemicals #2 and 6.
