3. REQUIREMENTS

3.1 General. The Contractor shall conform to all requirements specified in SFLC Std Spec 0000 and in this item, as applicable, during the performance of this availability.

NOTE

The requirements of paragraph 3.1 (General) applies to all work under the scope of this contract, whether explicitly stated in work items or not, and also to all other work subsequently authorized by changes, modifications, or extensions to the contract.

3.2 Fire watch requirements. The Contractor shall refer to 3.3.1.3 (Fire watch requirements) of SFLC Std Spec

0000, in accomplishing the following task:

2 (Rev-0)

Provide fire watch personnel and fire extinguishers for the duration of the availability period, during and beyond noted Coast Guard fire watch support.

3.3 Welding and brazing requirements. The Contractor shall perform all welding and allied processes, and NDI in accordance with SFLC Std Spec 0740.

3.4 HW disposal. The Contractor shall be responsible for all hazardous wastes generated by work under this contract. Label and package all hazard wastes in 49 CFR-approved containers, and in accordance with all other applicable Federal, state, and local laws and regulations. In addition, comply with applicable parts of 40 CFR

262, applicable to handling of hazardous wastes.

3.4.1 Along with the Government, the Contractor shall be contractually considered the co-generator of all hazardous wastes; be aware that the Government will make available its facility’s EPA Generator Identification

(ID) Number for manifesting of hazardous wastes.

3.4.2 The Contractor shall identify, arrange, and be responsible for the turnover of all hazardous wastes, within the confines of the Coast Guard shore facility, to the facility’s HM/HW Coordinator. Notify the ship’s HW

Coordinator prior to any transfers of HW from ship to shore.

3.4.3 The Contractor shall prepare a manifest of hazardous waste to be reviewed and signed by the HM/HW

Coordinator. Contact the HM/HW Coordinator for turnover of any hazardous waste; in addition, notify the

COTR 24 hours prior to any waste removals, and ensure that waste removals are conducted during normal business hours (0800-1600) on Monday through Friday (excluding holidays).

3.4.4 The Contractor shall be aware of the following:

3.4.4.1 No Contractor or Subcontractor shall have the authority to sign a Hazardous Waste Manifest using the

Coast Guard facility’s EPA Generator ID Number or remove contract generated hazardous waste from the Coast

Guard facility without COTR or KO-approval.

3.4.4.3 Local environmental regulations at the Government facilities may be more stringent than in many jurisdictions. As with all environmental regulations, it is the Contractor's responsibility to research, prepare for, and comply with, the local and state regulations.

3.4.4.4 Coast Guard facilities do not have Facilities Response Plans (see 33 CFR 154 Subpart F). It is the

Contractor’s responsibility to furnish the Facility Response Plan (FRP) when required for over-the-water liquids transfers to and from vessels. This requirement is applicable to transfers to/from vessels with an oil/fuel capacity of 250 barrels or more.

QA-1 - QUALITY ASSURANCE INSPECTION FORM

(PRESERVATION CHECKLIST)

Vessel Name: _______________________ Hull Number: ______________ CLIN No.: _____________ Work Item Title: ________________________________________________ Specific Area Being Preserved: ___________________________________________________________

CHECKPOINT 1 – COATING SYSTEM COMPLIANCE

Ensure all coatings are in compliance with COMDTINST M10360.3, Appendix C.

CHECKPOINT 2 - PAINT STORAGE

Ensure all coatings are kept at a temperature of 65 to 85°F at all times, unless otherwise specified by the coating manufacturer(s).

CHECKPOINT 3 - AMBIENT CONDITIONS

Ensure surface and surrounding temperatures are each between 50 and 90°F for water-based coatings, and 35 and 95°F for other coatings, unless otherwise specified by the coating manufacturer(s).

Ensure maximum relative humidity (RH) is as follows, from surface preparations through final curing of topcoat: 50% for tanks, voids, and vent plenum; and 85% for all other areas, unless otherwise specified by manufacturer(s).

Ensure surface temperature is at least 5°F above the dew point, unless otherwise specified by the coating manufacturer(s).

CHECKPOINT 4 - PRE-SURFACE PREPARATION

Remove surface contaminants (soluble salts, loose rust, mud, and marine growth) with low pressure fresh water wash down

(maximum 5,000 psi). If oil and grease are present, perform solvent cleaning, as per SSPC SP-1.

CHECKPOINT 5 - SURFACE PREPARATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure cleanliness of prepared surface is as per specification (i.e.: SSPC SP-12, SP-11, SP-10…).

Verify surface anchor profile (1.5-3.5 mils for abrasive-blasted steel surfaces; 1.0 mil (minimum) for power-tool cleaned surfaces; 1.0-1.5 mils for abrasive-blasted aluminum surfaces); and 1.5 –2.5 for surfaces to be coated w/single coat of inorganic zinc). Conduct 5 sets of 3 readings for the first 3 100-sqft areas, followed by 5 sets of 3 readings for each succeeding 1000-sqft area.

Measure soluble salt conductivity (5 measurements per 1000 sqft) – maximum threshold: 70 microsiemens/cm for non-submerged surfaces and 30 microsiemens/cm for submerged surfaces.

CHECKPOINT 6 - PRIMER COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Verify proper mixing and stand-in (induction) times.

Ensure no paint is applied when the temperature is expected to drop to freezing before the paint has dried.

Ensure surfaces are completely dry, unless otherwise allowed by the coating manufacturer(s).

Verify wet film thickness (WFT) at random, to prevent under or over application. Verify final DFT.

Brush out all runs, sags, drips, and puddles.

Perform visual inspection for holidays and other defects.

CHECKPOINT 7 – STRIPE COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer’s instructions.

After primer coat (mist coat after inorganic zinc), brush-apply un-thinned coat of same primer paint over edges, weld seams, cut-outs, and areas of complex geometries @ 3-4 mils wet film thickness (WFT).

CHECKPOINT 8 – TOP COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer’s instructions.

Verify proper mixing and stand-in (induction) times, as applicable.

Verify wet film thickness at random, to prevent under or over application.

Brush out all runs, sags, drips, and puddles.

CHECKPOINT 9 – FINAL INSPECTION

Verify final system dry film thickness.

Ensure that system cure is in accordance with manufacturer's recommendation for intended service.

Ensure potable water tank exhaust ventilation is maintained continuously from and during coating application through final system cure, to exhaust all solvent to the atmosphere and to prevent solvent entrapment.

For immersion coatings (including tank U/W body), record date and time of the following events:

Final coat application:_________/_________; Return to service or removal from environment controls: _______/_______

CHECKPOINT 10 – RECORD KEEPING

Complete, sign, and submit all provided QA Inspection Forms.
