BOARD ACTION: APPROVED X DENIED • WITHDRAWN • AMENDED • CONTINUED TO DATE SPECIFIC • CONTINUED TO DATE UNKNOWN • RETURNED TO STAFF • BOARD RECEIVED THE • REPORT/PRESENTATION OTHER-SEE MINUTES • Page 2 As part of the Reservoir Repair and Maintenance Program, Project No. 5024, involves the following improvements: • The exterior shell coating of all three tanks is heavily chalked and exhibits minor localized spot corrosion from mechanical damage, which will be repaired by applying an over-coating consisting of a zinc / hydrophobic acrylic / HDP acrylic paint. • The interior coating system of all three tanks is comprised of an epoxy coating that is in poor to fair condition on the roof and fair to good condition on the walls and floor. The appearance of corrosion is emphasized by the formation of rust bleed staining. The existing interior coating of all three tanks will be removed and replaced with a zinc / polyamidoamine epoxy coating. • On the Elm and Skyline tanks a second 36" X 36" roof hatch will be installed to meet current standards. • On all three tanks, to comply with Occupational Safety & Health Administration (OSHA) requirements, a new exterior steel ladder with safety cage plus handrailing mounted offset from the roof hatchway will be installed, plus a 30-inch diameter manway will be added on the tank wall for access. • To comply with California Department of Public Health (CDPH) requirements, the roof vent screens on all three tanks will be replaced to prevent contamination from birds, bats and insects, and a %" sample tap will be installed on each tank. • On the Ellery and Skyline Tanks one tamper-proof aluminum vent will be installed to insure continued compliancy with California Department of Public Health requirements and to satisfy security concerns as detailed in HR 3448, typical bio-terrorism prevention requirements. • All three tanks have severely corroded earthquake rods that are attached to the roof beams which will be replaced, the caulking and backer rod at the tank / concrete ringwall interface will be replaced, the liquid level indicator board will be replaced, and minor spot repairs will be performed. The interior and exterior coatings on all three tanks will be inspected by a National Association of Corrosion Engineers (NACE) Certified Inspection services firm. Staff is issuing a "Request for Proposals" for this inspection work and the consultant will be selected based on an estimated budget established at $100,000. FISCAL IMPACT: The reservoir repair and maintenance program, Project No. 5024, includes rehabilitation of nine steel tanks and three concrete tanks. Funds in the amount of $3,035,000 have been appropriated from the water replacement fund for Project No. 5024. The Engineer's Estimate, for the construction contract, for the rehabilitation of Ellery, Elm and Skyline tanks is $1,000,000.
