independent finding that this project is exempt from CEQA.
ALTERNATIVES /CONSIDERATIONS: Reject all bids, which is not recommended.
FINANCIAL IMPACTS: The funds required to complete this project, as shown in
Attachment 3, are $959,500. The total project cost of the Wet Scrubber Caustic Injection
System is anticipated to be $1,209,500, which includes design, bid price, construction,
contingency, and construction management. This project is included in the Fiscal Year
2015 -16 Capital Improvement Budget on page TP -13 with a total estimated project
budget of $9.0 million. Staff has conducted a budget analysis of the Treatment Plant
Program budget and concluded that adequate funds are available for this project.
