Contractor shall comply with applicable Federal, state, and local laws, codes, ordinances, and regulations in their entirety. Any reference to a specific portion of a Federal, state, or local law, code, ordinance, or regulation in this or any other item shall not be construed to mean that relief is provided from any other sections of the law, code, ordinance, or regulation.

3.5.1.1 USCG Generator status. Coast Guard Base Seattle is a Large Quantity Generator of Hazardous Waste and holds a WA State Department of Ecology permit.

3.5.1.2 Plans and permits. The CG Facility has unit specific permits including the following:

• National Pollutant Discharge Elimination System (NPDES) Storm Water (SW) Permit: Unit has an

NPDES SW permit which requires unit-specific procedures be followed for the storage and inspection of equipment and materials which may contribute contaminants to storm water discharges.

3. REQUIREMENTS

3.1 General.

3.1.1 CIR.

None.

14 (Rev-1)

3.1.2 Tech Rep.

Not applicable.

3.1.3 Protective measures. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces near the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness.

3.1.3.1 As per SFLC Standard Specification 6310 para 3.1.5, when the ambient condition parameters necessary for full paint cure or to meet environmental conditions, as required in SFLC Std Spec 6310 para

3.1.4 (Ambient condition parameters), cannot be met, provide the following suitable tenting, at no additional cost to the Government.

3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences). Known interferences include, but are not limited to the below-listed:

• Flight deck safety net assemblies.

• Talon grid cover.

3.1.5 Surface preparation optional methods. The Contractor has the option of using either high/ultrahigh pressure water jetting or abrasive blasting to achieve the required surface preparation, prior to application of the coating system specified in 3.3 (Preservation requirements). The Contractor may add abrasives to the waterjet stream, for one or both of the following reasons:

• Achieving greater productivity.

• Achieving the required surface profile.

NOTES AND CAUTION!

1. Waterjetting without abrasive addition does not provide any additional anchor profile to the surface, beyond what was present after the previous surface preparation.

2. Initial removal of the coating system around deck edges, fittings, and deck coaming may be by power tool cleaning in accordance with SSPC-SP-11.

3. Flight Deck surfaces are constructed of HY-80 steel and may NOT be heated to remove the existing covering.

4. During pier side surface preparation, suitable means to contain generated dust, waste water, paint chips, spent abrasives, and overspray must be provided or employed, as applicable. Plywood or net/canvas barriers are typically used to surround the area being blasted to contain stray steel shot.

When net barriers are used, the mesh size of the netting material must be small enough to ensure that the steel shot will be contained. In addition, net barriers, when used, must be overlapped where attached to stanchions, and anchored at the bottom for the entire net’s length between stanchions, to limit the clean–up and localize the blast medium. Steel shot on a deck is a foreign object damage (FOD) hazard and extreme care must be taken to prevent slipping when walking over contaminated areas.
