None.

3.1.2 Tech Rep.

Not applicable.

3.1.3 Protective measures.

3.1.3.1 General. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces in the vicinity of 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.

3.1.3.2 Specific. The Contractor shall abide by all lead and asbestos abatement compliance requirements, as specified in SFLC Std Spec 0000. Abide by the following additional safety precautions during the lead dust clean-up operation:

Separate contaminated areas from other areas.

Do not permit non-essential personnel in the work area.

Work in one compartment at a time.

Prevent dust from migrating to other areas, as follows:

· Seal doors, hatches, and all other openings between the work area other areas with an airtight barrier, such as fire-rated polyethylene; seal both sides (inside the construction area, and inside the adjacent area) to provide a secondary dust barrier and prevent the doors and windows from being used (post alternative emergency exits, if applicable).

· Ensure that the work area remain under negative pressure in relation to adjacent areas.

NOTE

Negative pressure means that more air is exhausted from the area than is supplied so that lead dust and asbestos particles are contained within the work area, and do not contaminate adjacent non-affected compartments. Exhaust air must be filtered with a suitable HEPA filter.

· Take, at a minimum, the following measures, to protect de-contamination workers:

· Use a HEPA (high-efficiency particulate air) vacuum - never use a conventional vacuum. A HEPA vacuum removes 99.97% of particles that are less than 0.3 microns in size.

· Never use compressed air; never dry sweep.

· Workers must wear a respirator which is approved by NIOSH and has N100, P100 or R100 filters (the cartridges are usually purple); respirators must be fit-tested to insure proper seal, and employees must be medically screened and trained prior to wearing a respirator (see the OSHA Respirator Standard, 29 CFR 1910.134).

· Workers must wear full-body protective clothing, head covering and shoes (or shoe covers).

· Workers must not leave the work area without having gone through a proper decontamination process, to prevent spread of lead dust to un-affected areas.

· Eating, drinking and smoking are prohibited in work areas.

· Workers must wash hands and face before eating, drinking or smoking.

· Workers must remove work clothes and shoes before leaving the work area, and seal work clothes in plastic.

· Workers must shower and wash hair as soon as possible after leaving the work area.

· Non-disposable work clothes must be washed separately from other clothes.

3.1.3.3 Remove protective covers, to allow for performance of lead dust cleaning and wipe sampling tasks, as specified in 3.2 (Clean-up particulars) and 3.3 (Clearance examination – post cleaning), respectively. Reinstall protective covers, after said tasks have been completed.

3.1.3.4 Remove and dispose of all protective covers, upon completion of work.

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:

Deck plates, including associated hardware.

Bilge pumps Electrical wiring Piping

3.1.5 Certification requirements. The Contractor shall ensure that all contractors and subcontractors performing cleanup or sampling must possess all applicable Federal and state certification licenses for lead work and lead sampling. Submit documentation of these certifications to the KO within 48 hours prior to commencing work.

3.2 Clean-up particulars. The Contractor shall, upon completion of existing lead ballast ingot removal and following installation of lead ballast containment boxes, accomplish the steps provided below in the compartment(s) designated for clean up, in addition to any other location used as a temporary stowage location for the lead ballast ingots:

NOTES

Ballast ingot removal and reinstallation is specified in a separate work item titled “Fixed Ballast (Lead Ingot), Remove and Reinstall”.

Step 1 - Debris Removal: Remove all gross debris, paint chips, etc. using either a vacuum with a HEPA filter or by spraying the materials with water in a spray bottle and picking up chips or large pieces of lead contaminated debris by hand.

Step 2 – Vacuum Cleaning: Using a suitable HEPA vacuum, clean all affected surfaces, following the following guidelines:

Begin that cleaning begins with high areas first – with overhead surfaces and bulkheads working downward.

Vacuum all surfaces in the compartment.

Work in the direction furthest from the entry door toward it.

Step 3 – Wet Cleaning: Following thorough HEPA vacuuming, wash all surfaces with any suitable cleaning detergent following the same cleaning pattern (high to low/ furthest from and toward entrance). Change the cleaning solution as it becomes dirty. Rinse all areas with a fresh cloth/mop. Do not reuse contaminated mops and cloths. Use a three-bucket system for cleaning. (Detergent solution in first bucket/ rinse water for mop in second/ surface rinse on deck and/or bilge surfaces.

Step 4 – Vacuum Cleaning: Perform a HEPA vacuum again as specified in “Step 2”.

Step 5 – Waste Disposal: Properly dispose of lead contaminated materials, in accordance with all applicable Federal, state, and local regulations.

WARNING

1. Work Wet, Work Smart, and Work Clean. DO NOT GENERATE DUSTS. It is easier to effectively clean an area when dusts are not being generated to resettle on previously cleaned areas! Worker exposures may be high during wet sweeping.

2 A wet/dry HEPA unit is ideal for working with leaded dust clean up.

3. Lead-contaminated objects that are porous or materials that may suffer damage from water may not be able to be sufficiently decontaminated by these methods and should be discarded.

3.3 Clearance examination – post cleaning. The Contractor shall accomplish the following tasks after completion of all cleaning operations,:

3.3.1 Visual inspection. In the presence of the COR, conduct a visual inspection to ensure that no chips, dust, or cleaning material haze are present. Submit a CFR.

3.3.2 Wipe sampling. In accordance with ASTM 6966 and as designated by the Coast Guard Inspector conduct wipe sample clearance testing in ten locations for each designated compartment, to ensure there are no lead dust residues in excess of the below-listed concentrations. As designated by the COR, conduct clearance testing in two locations in any other location used as a temporary stowage location for the lead ballast ingots. Submit a CFR with sample results.

200 micrograms/square foot (mcg/ft 2) –for all other areas.

3.3.2.1 Ensure dust lead samples are analyzed by a laboratory certified by the National Lead Laboratory Accreditation Program (NLLAP) or the American Industrial Hygiene Association.

3.3.2.2 If laboratory analysis shows lead concentrations in excess of the thresholds specified above, then perform lead dust cleaning, and take subsequent wipe samples until the concentration of lead falls below the above standards.

NOTE

For a listing of certified laboratories, go to www.aiha.org.

3.3.2.3 The Contractor shall be aware that the Coast Guard reserves the right to coordinate additional wipe clearance testing, at no cost to the contractor, to verify the sample results.

3.2.3.4 The Contractor shall witness all additional wipe clearance testing conducted by the Coast Guard to verify where and how samples were collected – and thus, prevent contract disputes.

3. REQUIREMENTS

3.1 General.

3.1.1 Coating system visual inspection The Contractor shall perform a visual inspection of the existing U/W body coating system. Document the condition found as “Condition A” or “Condition B”, as applicable (see 3.2 “Partial – Condition A” preservation particulars and 3.5 “Partial - Condition B” preservation particulars (see 5.1 (Definitions)).

3.1.2 Reporting The Contractor shall submit a C.I.R.

3.1.2 Technical Representative.

Not applicable.

3.1.3 Protective measures. The Contractor shall protect non-affected vessel’s equipment, components, and spaces during surface preparation and coating application procedures, as specified in SFLC Std Spec 0000, paragraph 3.3.3 (Vessel component, space, and equipment protection). Specific areas/equipment/components to be protected include, but are not limited to:

· All scuppers and overboard discharges.

· Waterline area where U/W body coating system interfaces with freeboard coating system (unless u/w body surfaces are also being preserved).

· Fathometer transducer surfaces.

· Sea valve openings.

· Propeller shaft bearings and seals.

· Rudder bearings.

· Propellers

3.1.4 Interferences. The Contractor shall be aware that interferences in way of work include, but are not limited to the below-listed. Handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences):

· Sea chest grating.

3.1.5 Initial inspection. Prior to removing the existing coating system, the Contractor shall inspect and verify whether or not all draft marks have permanent markings (weld beads or impressions), showing their location on the hull. Submit a CFR.

3.1.6 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 3.2 (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.

NOTE

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

3.2 “Partial – Condition A” preservation particulars. If “Partial - Condition A” exists the Contractor shall accomplish the following tasks:

3.2.1 Surface preparation.

3.2.1.1 Clean all areas where the U/W hull substrate is exposed to “SSPC-SP 10/NACE No. 2, Near-White Blast Cleaning”, with a 1.5 to 2.5 mil anchor profile; or to "SSPC-SP 12/NACE No. 5, WJ-2/L”.

3.2.1.2 Lightly clean the remaining surfaces of the u/w body to “SSPC-SP 7/NACE No.4, Brush-off-Blast Cleaning”, or to “SSPC-SP 12/NACE No. 5, WJ-4”.

3.2.1.3 Where new coating is to be merged into existing coating, provide an approximately 3-inch wide, smoothly tapered boundary from the existing coating into to the prepared surfaces.

3.2.2 Coating application.

3.2.2.1 Apply anticorrosive (AC) coating conforming to MIL-PRF-24647, to match existing color scheme, and achieve a total DFT (existing and new coats) of 10-12 mils DFT over the U/W hull surfaces.

3.2.2.2 Apply ablative copper antifouling (AF) paint conforming to MIL-PRF-24647 (Type II, Class 1, Grade A), to match existing AF color scheme, and achieve a total DFT (new and existing AF coats) of 10-12 mils over the u/w body surfaces. Where AF paint is being applied over AC undercoating, ensure that the AC coating is still tacky, before applying AF paint.

3.3 Draft mark painting. The Contractor shall paint all draft marks with one white (17925) coat of a “Polysiloxane” coating, at 2.0-3.0 mils DFT.

NOTES

1. Existing coating system on the U/W body surfaces may have a nominal thickness in excess of that which was originally installed, as a result of “patch-coats” applied during past drydock availabilities.

2. Surfaces being preserved are considered “critical-coated surfaces”.

3. A “Tooke Paint Inspection Gage” may be used for inspection and thickness measurement (in accordance with ASTM D4138) of single or multiple coats on any substrate.

3. All authorized coating materials and suppliers, and coating colors are listed in COMDTINST M10360.3 Appendix C (Authorized Coatings for Use on Cutters and Boats) and Chapter 11 (Cutters and Boats Colors – Exterior and Interior), respectively.

3.4 In-process quality control measures. The Contractor shall abide by all the safety, preservation, and quality control requirements specified in SFLC Std Spec 0000, paragraph 3.2.4.2 (In-process QC measures for “critical-coated surfaces).

3.5 “Partial - Condition B” preservation particulars. If “Partial - Condition B” exists the Contractor shall accomplish the following tasks:

3.5.1 Surface preparation. Remove all remnants of AF coating (if existing), all visible oil, grease, dirt, dust, loose mill scale, loose rust, and loose anti-corrosive (AC) coating by water-jetting (SSPC-SP 12/NACE No.5) or abrasive-off-blasting (SSPC-SP 7/NACE No.4).

3.5.2 Coating application.

3.5.2.1 Apply one coat of anticorrosive (AC) coating conforming to MIL-PRF-24647, at 5-6 mils DFT, to match existing color scheme.

3.5.2.2 While the new AC coat is still tacky, apply two coats of copper ablative antifouling (AF) paint, conforming to MIL-PRF-24647; apply one additional coat of AF paint over the boot-top area surfaces, at 5.0-6.0 mils DFT.

NOTE

Existing coating system on the U/W body surfaces may have a nominal thickness in excess of that which was originally installed, as a result of “patch-coats” applied during past drydock availabilities.

3.5 Draft mark painting. The Contractor shall paint all draft marks with one white (17925) coat of a “Polysiloxane” coating, at 2.0-3.0 mils DFT.

NOTES

1. Surfaces being preserved are considered “critical-coated surfaces”.

2. A “Tooke Paint Inspection Gage” may be used for inspection and thickness measurement (in accordance with ASTM D4138) of single or multiple coats on any substrate.

3. All authorized coating materials and suppliers, and coating colors are listed in COMDTINST M10360.3 Appendix C (Authorized Coatings for Use on Cutters and Boats) and Chapter 11 (Cutters and Boats Colors – Exterior and Interior), respectively.

3.5 In-process quality control measures. The Contractor shall abide by all the safety, preservation, and quality control requirements specified in SFLC Std Spec 0000, paragraph 3.2.4.2 (In-process QC measures for “critical-coated surfaces).

4.1 Definitions.

4.1.1 U/W body. The underwater body is defined as the areas from the bottom of the keel to the upper edge of the boot-topping, as shown on Coast Guard Drawing 64 ANB 0103-001, including transducer hull rings, sea chests, bilge keels, struts, rudders, skegs, gratings, and rope guards.

4.1.2 "Partial - Condition A”. The condition that exists where up to 33% of the U/W body hull substrate is exposed.

4.1.2 "Partial - Condition B". The condition that exists where the anticorrosive (AC) coating system is damaged, but the hull is not exposed.
