Section 2: Painting & Fiberglass Repair - Teak Refinishing

Potential Environmental Impacts:

Teak cleaners which contain acids and caustics can be toxic to marine life when spilled in the water.

Best Management Practices:

Avoid teak cleaners containing acids (such as phosphoric acid or oxalic acid), or those labeled "caustic, corrosive, or acidic." Clean teak with a mild, phosphate-free detergent with bronze wool, if possible.

If sanding teak, use a dustless or vacuum sander.

If possible, conduct teak refinishing in upland maintenance area. If not possible, use safer cleaners and avoid flushing excess teak cleaner and teak oil into the marina basin.

Regulatory Issues:

A hazardous waste determination must be conducted for spent teak cleaner, and for any materials used to clean a spill to establish whether or not their disposal is subject to hazardous waste regulations. To determine if they are hazardous, the generator must either have waste materials tested or utilize reliable "knowledge of process" information for the waste (if available) [40 CFR 262.11, click here]. Such information could include testing by haulers, or studies by industry trade groups. For more information on New York hazardous waste testing requirements, click here. If hazardous, spent teak cleaner must be managed in accordance with hazardous waste storage and handling requirements [40 CFR 262.11, click here].

If there is a stormwater discharge from your facility and you clean teak outdoors, you may have to register for a General Permit for the Discharge of Storm Water Associated with Industrial Activity ("Storm Water General Permit"). For more information on stormwater permitting in New York, click here.
