3.2 Operational test - initial. Prior to commencement of work, the Contractor shall witness Coast Guard personnel perform an operational pre-test of all items and shipboard devices to be disturbed, used, repaired, or altered, (e.g. TLIs, pumps, etc.) to demonstrate existing operational condition and to determine a more precise scope of cleaning required. Prior to system cleaning the Contractor shall submit a CFR that details any required growth repairs identified during the operational test and that specifies a “Cleaning Plan” described below, based on the observed condition of the systems.

3.2.1 Cleaning Plan. The cleaning plan shall contain the following

• A list of qualified personnel who will disassemble machinery or handle chemicals.

• An SDS for every chemical proposed for use.

• A step by step description of the procedures and methods that will be used to clean the systems

• A list of locations in the sewage and grey water piping system where piping lines will be opened and components will be removed. At a minimum the piping shall be opened at 3 separate sewage system clean-out locations and 3 separate grey water system clean-out locations for “before and after” inspections to determine the extent of cleaning required and to verify cleaning was adequately performed. These locations shall be pre-approve by the COR and included in the cleaning plan CFR.

3.3 Cleaning and Inspection Requirements. After the COR approves the “Cleaning Plan” the Contractor shall perform “Chemical Cleaning of Piping”, “Tank Cleaning”, “Inspections” and “Miscellaneous” in accordance with the approved “Cleaning Plan”, and as described below. Clean, in their entirety, all sewage and grey water system interior surfaces (e.g. sewage and grey water ppg interiors, pump interiors, valve interiors, all sewage and grey water tank vent lines interiors, sewage vacuum switch manifold interiors, fire main sprinkler pipe interiors and spray hole interiors in main sewage tank used to flush sewage tank, overboard/to shore connection discharge pump and all related valve and pipe interiors, etc.)

that may come in contact with sewage or grey-water, by removing all obstructions, clogs, uric scale, and waste build-up on piping and component interiors, ensuring subsequent free unobstructed flow of waste solids and fluids.

NOTE

Before filling system with descaler ensure all openings below the fill point are blanked off or plugged.

3.3.1 Chemical Cleaning of Piping. Chemically clean all piping and component interiors using a commercially available biodegradable sewage/grey-water system descaler (e.g. SEW CLEAN, RYDLYME, etc.). Fill the systems with descaler and hold for a long enough period to clean the systems as described above (minimum of 24 hours). After cleaning is complete drain and dispose of all sewage and grey water system contents.

3.3.2 Tank Cleaning. Clean the interior surfaces of the Grey Water Tank 3-17-0-W, Sewage Holding Tank 2-4-0-W, and sewage vacuum accumulation tank until free of all foreign materials, sediment, and sludge and remove all persistent residues, residual wash media, and moisture with clean lint-free cloths.

Remove, clean, and re-install all tank interior components (e.g. TLIs, limit switches, eductors, etc.).

Renew all zinc anodes installed in the sewage tank and grey water tanks using Government-furnished property. Remove and dispose of all sewage system contents and collect, contain, and dispose of all wash media and cleaning materials in accordance with all applicable Federal, state, and local regulations.

Remove all unused chemicals from USCG property immediately upon completion of work item.

22 (Rev-0)

3.3.3 Inspections. After cleaning, inspect the piping interior at the locations specified in the “Cleaning Plan” using a borescope in the presence of the COR, verify that all solid deposits, visible to the unmagnified eye, have been removed. Visually inspect all system components (e.g. TLIs, limit switches, pressure switches, tank interior surfaces, fasteners, gasket seating surfaces, manhole cover surfaces, etc.)

for excessive wear, damage, and all other notable discrepancies. Open and vacuum-clean the control panel assembly and inspect for any indications of overheating or loose wiring or connections. Submit a

CFR.

3.3.4 Miscellaneous. Do not drain any fluids (e.g. sewage, grey water, fresh water, etc.) into any space, bilge, or exterior location. Take all precautions required to prevent contamination of personnel and spaces in accordance with all applicable Federal, state, and local regulations. Renew all disturbed soft components (e.g. seals, gaskets, o-rings, etc.). Do not use the sewage pump installed in the system to offload sewage system contents.

3.3.4.1 Plug log. Plug all unattended openings in the system. Plugs shall be fitted with a lanyard, ring or other device to prevent loss of the plug inside the system. Create and maintain a written log of each plug that specifies the location of each. Remove and dispose of all plugs upon completion of work. Furnish the plug log to the Coast Guard Inspector during the performance of close-out inspections.

3.3.4.2 Use of Coast Guard Sewage and Grey Water Disposal Facilities. If “YES” is denoted in table beneath paragraph 1.1 (Intent), the Contractor may offload and dispose sewage and grey water system contents into the Coast Guard pier facility tanks in lieu of a contractor furnished tank truck, otherwise the contractor shall dispose of all waste using the contractor’s disposal facilities.

3.4 More Intrusive Cleaning and Repairs. After op testing or opening and inspecting the system, if the Contractor determines that more intrusive cleaning methods (e.g. piping disassembly with subsequent pressure-washing, flexible auger cleaning, etc.) will be required to meet the requirements in 3.3 (Cleaning and Inspection Requirements) then Submit a CFR that details a proposal for performing that work.

NOTE

Depending on the condition of the system at the contract start date, chemical cleaning may not adequately remove all obstructions, scale, and build-up present. More intrusive cleaning methods, such as pressure washing, flexible auger cleaning, or other mechanical means of cleaning, may be required to remove all obstructions, scale, etc. These more intrusive methods are in scope of this work item and the contractor may be required to use one or more them, in the appropriate quantities, to achieve minimum cleaning requirements.

3.4.1 Repairs. In addition to the cleaning and inspection requirement specified herein, the Contractor shall perform the repairs described in Table 2 beneath paragraph 1.1.1. If “NONE” appears in Table 2 then there are no know repairs required to the systems.

3.5 Closing tanks. The Contractor shall notify the COR at least 24 hours prior to closing the tank. After completion of all authorized repairs and after the COR inspects all work performed, close the tanks.
