The Coating system shall include a primer (3 mils) that contrast with the white for the intermediate and finish coats. The Contractor shall allow the primer to dry and cure as per manufacturer’s instructions. After the primer is cured, the Contractor shall apply an intermediate of epoxy coat (4 mils) and a final coating of epoxy (5 mils), total system 12 mils. The Contractor shall follow the manufacturer’s directions when applying the coatings. Intermediate and finish coats may be applied by any method that attains an acceptable coating except that rolling shall not be used for interior coatings except when required for rough pitted services. Once the final coating is cured and dried, the Contractor shall allow the Government to inspect the tank’s interior. After the coatings are complete, the Contractor shall perform a dry film thickness testing and submit the results to the Government.

4.4 INSPECTION AND TESTING: The Contractor shall ensure that the thickness of coating is achieved. Coating film thickness shall be verified by measuring the film of each coat as it is applied and the dry film thickness of the entire system. A test report shall be prepared and submitted to the Government at the conclusion of the dry film thickness testing indicating the film thickness gauge used, the locations where tests were conducted, the dry film thickness at each location, and the name of the person conducting the tests. The test report shall be certified by a representative of the Contractor who witnessed the testing. After the final coating is complete, the Contractor may continue with ladder installation.

The Contractor shall perform a holiday test to ensure that no holes or discontinuities are present on the final coating.

4.5 LADDER INSTALLATION: The Contractor shall provide and install new ladder with fall protection slider and components. After coating is complete, the Contractor shall proceed with the ladder installation as per drawing. Prior to ladder’s installation, the Contractor shall have the Government inspect the ladder for any damages or imperfections. Contractor shall correct properly any scratches on the coating caused during ladder’s installation. After the ladder is installed and inspected by the Government, the Contractor may proceed with the tank (and interior’s components) disinfection.

4.6 CATHODIC PROTECTION REPLACEMENT: The cathodic protection installation constructor shall provide all engineering services, materials, equipment, labor, and supervision for the installation of an automatically controlled impressed current cathodic protection system to provide corrosion control for the interior submerged surface of the specified tank. All work furnished shall be in accordance with A.W.W.A. Standard D104, ANSI/NSF 61 and features included in this specification. All hardware used in conjunction with the system shall be protected against corrosion. The existing rectifier unit and conduit system shall be re-used. All other items shall be replaced with new components as outlined within this specification.

Contractor shall remove, supply and install seven (7) each suspended anodes including its components, brackets and hangers. Anodes shall be equal or approved to Harco Technologies Corporation. The anodes shall be provided and installed as follow:

1. Six (6) each. – High silicon cast iron anode strings, each containing 5 – 1 1/8” x 9” segments, installed on a 10 foot radius, hanging 3 ft. off the tank floor.

2. One (1) each. – High silicon cast iron anode strings, each containing 15 – 1 1/8” x 9” segments, installed down the center of the riser pipe, suspended 5 ft. off the bottom of the riser.

The permanent reference electrode shall consist of a copper-copper sulfate electrode which is manufactured to remain stable (plus or minus 10MV) for minimum of twenty (20) years. The reference electrode to lead wire connection shall be encapsulated to prevent water migration. All wiring within the tank shall be insulated to prevent copper conductor to water contact. All materials in contact with the water or exposed to the interior of the tank shall be classified in accordance with ANSI/NSF 61 "Drinking Water System Components”. This requirement shall be met under testing conducted by a product certification organization accredited for this purpose by the American National Standards Institute. Electrical connections within the tank shall be sealed to prevent water migration. Contractor shall submit copy of company registration and materials certificate to the government verifying ANSI/NSF 61 system components classification. Electrical work shall be in accordance with the National Electrical Code. The system shall be installed by personnel specifically trained by the constructor to provide all workmanship required for corrosion control performance. After installation the Contractor shall test anode as per USAF procedures. The Contractor shall submit to the Government a field test report of the cathodic protection system.

The anode suspension system shall be in accordance with ANSI/AWWA Standard D104, Section

4.2.4.2.2 Type C, Vertical System. The anode lead wire for vertical suspension shall be attached to a porcelain insulator bracket bolted to the interior of the tank roof. Hand hole assemblies used for the installation of vertical anode suspension systems from the roof of the tank shall consist of a 6" diameter acrylic plastic cover, rubber gasket, and an acrylic plastic bar with a stainless steel bolt assembly for each 5" diameter access opening.

The existing anodes were manufactured by Harco Technologiess Corporation; and an exhibit is enclosed for reference only. To the best of the Government's knowledge; the anodes in the tank were installed as shown on exhibit # 2. However; minor deviations may had happened.
