Staff requested that the board direct them to proceed with the project as previously approved. The board in March requested staff analysis of impacts that could come from delaying the repair of the cover, in an effort to save money on the $111,000 project. The agency received a letter of rebuke from the California Department of Public Health, warning of possible increased requirements if the project did not commence as planned. Joseph Spano of the Division of Drinking Water and Environmental Management in a letter April 7th said the Health Department had leaned that AWA “may postpone the replacing of the deteriorated floating cover on the Tanner clearwell until fall of this year.” Spano said the “department strongly opposes this plan and recommends that AWA” replace the cover as originally planned. The letter notified the board that if the project did not commence, AWA would be required to do daily chlorine reporting and daily inspections of the cover; and the state would do weekly analyses for coliform bacteria density. Spano also threatened that if the project was not resumed as planned, AWA would be required to “thoroughly review” its July 2000 Tanner “Clearwell Floating Cover Operation and Maintenance Plan.” The AWA board voted 5-0 to approve staff recommendations, without debate, or a staff presentation. Interim General Manager Gene Mancebo said the board directed staff to look at a possible delay until fall to ease cashflow issues, and see if any adverse costs would occur. Staff found cost impacts via the contract, and “simultaneously” got the letter from the DHS saying that its requirements that would also add to costs. The report by John Griffin said AWA’s board awarded a contract March 3rd to Layfield Environmental Services, which ordered the new cover and received approval from Public Health for its replacement plan, which included a May 14th completion date. March 25th, the board asked staff to “investigate potential cost implications” of delaying the project until the fall. The board faced paying $50 a day to Layfield for a contract suspension that was not the “fault of the contractor.” In 3 months it would cost $4,500, and 6 months cost $9,000. AWA could also face delay and “extended overhead claims.” After a 60-day suspension, the “contractor has the option of terminating the project,” which would cost the agency to rebid.
