- Paint Spraying
Paint spraying has potential air and water quality impacts. Most
paints contain volatile organic compounds (VOCs) which evaporate
quickly and are ignitable. Many paints are also toxic. When released
to the atmosphere, VOCs combine with combustion emissions of nitrogen
oxides (NOx) to form ground level ozone, which damages lungs and
degrades many materials. Marine paint may be toxic to aquatic
and marine life.
paint spraying. Paint spraying may be conducted:
designated structures with ventilation and filter systems;
- at designated
shore-side areas away from open water, with temporary structures
or plastic sheeting provided to minimize the spreading of overspray;
- in covered
slips, with tarps and sheeting installed with a tight seal between
the vessel being worked on and the floats or walkway surface.
Prohibit paint spraying on the water without protective sheeting.
Be sure to remove the protective sheeting with care to prevent
loss of accumulated waste material into the water.
outdoors with protective sheeting, avoid working on windy days
when controlling the protective covering and the paint spray is
spray equipment with high transfer efficiency. Paint guns used
in spray booths should be either High Volume Low Pressure (HVLP)
or High Efficiency Low Pressure (HELP) which are rated at 65%
efficient paint transfer. HVLP guns can reduce overspray by 25%
to 50%. For more information on HVLP painting systems click on
the Related Resources and Information on this Topic button at
the bottom of this page. For examples of HVLP spray painting
spraying also requires less pressure, produces little overspray,
and uses relatively little paint. However, it does require an
electrically conductive surface which may limit its use in marina

and thinners by draining the clean product off the top once solids
use brushes and rollers instead of paint sprayers since paint
spraying is potentially more wasteful and more harmful to the
environment than applying paint by hand.
In New York, most boat bottom paints are considered pesticides.
Marinas that sell or apply these paints must follow the state's
pesticide management rules which require a business license and
certification requirements for those who apply the paint. For

The use of
spray guns for painting may require an air emission permit depending
on the amount of painting done and the location of the facility.
For more information about air emission permits, your state environmental
agency should be contacted. For more information regarding air
regulations related to marinas in New York, click
You must determine if your painting wastes (including leftover
paints, spray gun solvents, and rags) or any materials used to
clean a spill, are hazardous by having the materials tested or
by utilizing 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 they are hazardous, they must be managed
as a hazardous waste. For more information on New York's Hazardous
Waste Regulations and storage requirements, click
If there is a stormwater discharge from your facility and materials
associated with spray painting may come into contact with precipitation,
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
Paint cans and other containers that have residues of hazardous
(e.g., oilbased) paints must be handled as hazardous waste unless
they have been "emptied," which means the container
has been cleaned following directions given on the label. In some
cases this means the container is drained of all material that
can be removed from them by normal methods (e.g., pouring or pumping),
AND no more than one inch (or 3% by weight) of residue remains
in the container [40 CFR 261.7, click
here]. "Emptied" containers of hazardous
paints and those that have dried out residues of non-hazardous
(e.g., latex) paints may be recycled as scrap metal, or disposed
of in the regular trash.
