3.3.3.1.1 Surface profile measurements. One surface profile measurement must be taken for every 200 square feet for the first 1000 square feet; for each additional 500 square feet or less, one profile measurement must be taken.

Profile measurements must be taken in accordance with SFLC Std Spec 6310, paragraph 3.1.8.3 (Surface profile measurements). A “measurement” for surface profile is defined as follows:

• ASTM D4417, Method B: One profile measurement is the average (mean) of 10 individual readings.

• ASTM D4417, Method C: One profile measurement is the average (mean) of 2 individual readings.

3.3.3.1.2 Soluble salt conductivity measurements. 5 conductivity measurements must be taken every 1000 square feet. For submerged (immersed) applications conductivity measurements must not exceed 30 microsiemens/cm.

For non-submerged (non-immersed) applications conductivity measurements must not exceed 70 microsiemens/cm. If a conductivity check fails, clean the surface in accordance with SFLC Std Spec 6310, paragraph 3.1.8.5 (Soluble salt removal).

3.3.3.1.3 Coating thickness measurements. Three area measurements must be taken for the first 1000 square feet;

3.5.2 Test and procedures. The Contractor is required to promptly conduct tests and procedures for the purpose of assessing whether operations are in compliance with applicable Environmental Laws. Analytical work must be done by qualified laboratories; and where required by law, the laboratories must be certified.

3.5.3 Regulatory notifications. The Contractor is responsible for all regulatory notification requirements in accordance with Federal, State and local regulations. In cases where the Coast Guard must also provide public notification, such as storm water permitting, the Contractor must coordinate with the Contracting Officer or COR, and if work is being performed at a USCG Facility, the local Facility Engineer or Engineering Officer. The

Contractor must submit copies of all regulatory notifications to the Contracting Officer and the local Facility

Engineer or Engineering Officer prior to commencement of work activities. Regulatory notifications must be provided for including but not limited to demolition, renovation, National Pollutant Discharge Elimination System

3.5.4 Environmental manager. The Contractor must appoint in writing an Environmental Manager for the project, who is responsible for coordinating Contractor compliance with Federal, State, local, and station environmental requirements. The Environmental Manager must ensure compliance with Hazardous Waste Program requirements, including hazardous waste handling, storage, manifesting, and disposal; implement the Contractors’

Environmental Management Plan; ensure that all environmental permits are obtained, maintained, and closed out;

ensure compliance with Storm Water Program Management requirements; ensure compliance with Hazardous

Materials including storage, handling, and reporting requirements; as well as coordinate any remediation of regulated substances such as lead, asbestos, and polychlorinated biphenyl (PCB). This may be a collateral position; however the individual must be trained to accomplish the following duties; ensure waste segregation and storage compatibility requirements are met; inspect and manage Satellite Accumulation areas; ensure only authorized personnel add wastes to containers; ensure all Contractor personnel are trained in 40 CFR requirements and individual position requirements; coordinate removal of waste containers; and maintain the Environmental

Records binder and required documentation, including environmental permits compliance and close-out.

3. REQUIREMENTS

3.1 General. The Contractor must refer to Coast Guard drawings 627 WMEC 627 WMEC 123-002, 627

WMEC 123-003, 627 WMEC 261-001 and 627 WMEC 261-002 for guidance in accomplishing this work.

3.1.1 CIR. The Contractor must submit a CIR for the inspections listed in the following paragraph(s):

• 3.6 (Ultrasonic thickness (UT) measurement).

3.1.2 Tech Rep.

Not applicable.

3.1.3 Protective measures. The Contractor must furnish and install all protective measures in accordance with SFLC Std Spec 0000, paragraph 3.3.3 (Vessel component, space, and equipment protection).

3.1.4 Interferences. The Contractor must handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences). Known interferences include, but are not limited to the following: up to a total of 200 gallons of fuel.

NOTE

Vessel may come in with less tank fluid contents than specified above. The

Contractor is responsible for providing all materials, equipment and services necessary to comply with local environmental regulations.

3.1.4.1 The Contractor must follow the fluid handling plan in accordance with Coast Guard Technical

Spec D-123-2046 when moving fluid between tanks to ensure adequate stability of the vessel.

3.2 Operational test, initial. Prior to commencement of work, the Contractor must witness Coast Guard personnel perform an initial operational test of all items or shipboard devices to be disturbed, used, repaired, or altered, to demonstrate existing operational condition. Submit a CFR.

3.3 Cleaning requirements. The Contractor must remove tank cover(s) and clean tank interior surfaces free of all foreign materials, such as residual water, sediment, sludge, rust, and bacterial growth, taking care not to damage the coating system (if applicable).

3.3.1 Remove cleaning media and residues continuously during the washing process. Wash the tank with high-pressure cold fresh water before it has a chance to dry after emptying. Do not use steam; it can damage the tank’s coating.

3.3.2 Drain and dry the tank using a portable air-driven pump. When dry, and after final visual inspection, close the tank. Submit a CFR.

WARNING

Do not use the Fuel Service or Transfer systems to drain water from the tank.

15 (Rev-0) complete chain of custody record of the removed tank contents and generated wastes, from the vessel to the point of final destination or delivery. Submit document to the COR upon completion of work.

3.5 Visual inspection. The Contractor must visually inspect all tank interior surfaces, including, but not limited to bulkheads, floor and overhead plating, structural members, manhole cover surfaces, fasteners and gasket seating surfaces.

Notify the COR at least 24 hours prior to closing the tank(s) and ensure tank closure is accomplished in the presence of the Coast

Guard Inspector. After satisfactory inspection by the Coast Guard Inspector and completion of all authorized repairs, close tank manhole cover(s) with new gasket material conforming to AMS-C-6183.

Chase threads on studs to ensure even installation of the access covers.

3.7.1 Renew 100% of the nuts with Nickel-Copper alloy (monel) nuts meeting QQ-N-281, Class A or B.

The nuts and bolts must be of different classes to prevent galling.

NOTE

Coast Guard personnel will operate all shipboard machinery and equipment.

1. The calibrated load bank must be connected to the Power Supply using the helo start cable supplied with the cutter used for starting the aircraft. The cable must be adjusted prior to conducting the test so that its length is sufficient to service the aircraft in its normal landing position on the flight deck. If required to make connections to the load bank, it is permissible to conduct the test before installing the helicopter end plug.

2. The voltage at the aircraft end of all installed system servicing cables must be between 24.0 to 29.0 volts for steady state load currents from 0 to 300 amperes.

3. Perform full load test at 300A for 60 minutes. Record values at the conclusion of the full load test.

Increase no-load voltage to 28.5V prior to start of this burn-in test to ensure output voltage will not drop below 24.0 during the burn-in period.
