b) In addition to the above requirements, spray-paint application must be contained to prevent paint from contacting stormwater or surface waters and meet the spray painting requirements of PSNS&IMFINST 5090.10, Air Pollution Control Plan.

3) Floating Work Platforms Used for In-Water Vessel Maintenance BMPs. All necessary precautions should be taken by personnel onboard the float to prevent liquids (such as paints, cleaning materials, petroleum products and unsecured materials) from entering into the water from the float. Any 1 gallon or greater container of paint or any other liquid product for painting or surface preparation must be provided with secondary containment when used onboard a float. All roller pans used on a float must be provided with secondary spill containment. Secondary spill containment capacity is equal to the entire volume of the container plus 10 percent of the volume of that same container.

BMP 9 TREATED LUMBER PRODUCTS

1) Treated wood shall only be used when required by PSNS & IMF or higher-level instructions.

2) Collect all construction debris including sawdust and drill shavings or dust to prevent entry into the aquatic environment.

3) Whenever possible, make cuts and perform machining operations in the shop or under cover.

4) Store treated lumber under cover and not in contact with the ground when stored outside, unless the contractor can prove the material used for the treatment of the lumber is the same as used by PSNS & IMF or that it is similarly non-toxic to marine waters.

BMP 10 DISCHARGES INTO STORM DRAINS

1) Do not discharge anything other than stormwater to a storm drain unless authorized by Code 106.32 in accordance with appendix C of PSNS&IMFINST

5090.30 and PSNS&IMFINST 5090.9.

BMP 11 OUTDOOR WORK AREAS

1) Mix paints and solvents indoors or in a cofferdam designed to prevent spills to Sinclair Inlet or storm drains.

2) Equipment and supplies must be on-hand for the control and clean up of liquid or debris spills. Examples of items you will need in a spill kit include drop cloths, absorbents, rubber mats, tape, tarps, brooms, or vacuums. Design your spill kit for the material being used.

3) Metal work areas must be constructed to prevent rainwater from contacting the work process and/or debris. Code 106.3 can grant an exemption if the size of the work piece reasonably precludes conducting the work under cover.

4) Metal work areas intended for use for more than one month must be completely enclosed. The enclosure shall be constructed such that debris cannot be washed out of the enclosure. Exhaust vents from work areas must be filtered to capture particulate.

BMP 12 SOLID WASTE RECEPTACLES

1) Solid waste receptacles shall be placed throughout the facility to promote the proper disposal of waste.

2) Solid waste containers shall be covered. Waste containers equipped with drains shall be plugged.

3) Solid waste containers shall be closed at all times except when waste is being added.

BMP 13 STORM SEWER SYSTEMS CLEANING

1) Inspect catch basins and storm water treatment systems at least yearly.

2) Clean oils, debris, sludge, etc., from catch basins, settling/detention basins, oil/water separators, conveyance systems, and storm water treatment systems regularly, to prevent the contamination of stormwater. Clean and maintain stormwater treatment systems per the manufacturers' specifications.

Clean catch basins when there is less than 6-inches clearance from the debris surface to the invert of the lowest pipe.

3) Label stormwater drains with a warning similar to, “Dump no waste.

Drains to the bay."
