BEST
MANAGEMENT PRACTICES FOR
BOAT
MANUFACTURING AND REPAIR FACILITIES
Best
management practices can be thought of as using "good
housekeeping"
practices. Listed below are several
procedures to
operate
your facility and minimize the risk of contamination to the
environment.
1. Solvents,
spent solvents (i.e. acetone, MEK, etc.), solvent
mixtures
and most resins used or produced during boat
manufacturing
are hazardous waste and must be properly disposed of
by
a permitted hazardous waste transporter, recycled by a
permitted
recycler, or distilled and recycled using a solvent
recovery
unit at your facility.
a.
If the waste solvent is recycled
by the facility generating
the
waste, the solvent stillbottoms must be collected and
treated
as hazardous waste (as described above), unless
proven
otherwise.
b.
If the waste solvent is recycled
by a permitted solvent
recycler,
receipts must be obtained from the recycler and
maintained
at your facility.
c.
The container must be compatible
with the hazardous waste
stored in them and
must meet DOT standards. Each container
is
to be marked with the date that the storage began and
marked
with the words "Hazardous Waste".
d.
In all cases when a RCRA hazardous
waste is produced, a
permitted
hazardous waste transporter must be used to
transport
the waste to a federally approved hazardous waste
treatment
or disposal facility. Hazardous waste
manifests
must
be kept at your facility, available for review. The
facility
generating the hazardous waste is required to obtain
an
Environmental Protection Agency identification number by
contacting:
Notification
Coordinator
Bureau
of Waste Planning and Regulation
Florida
Dept. of Environmental Protection
Twin
Towers Office Building Room 421
2600
Blair Stone Road
Tallahassee,
Florida 32399-2400
(904) 488-4805
2. Waste
oil and waste fluids must be stored in clearly marked
containers
that are in good condition; stored on a bermed, impervious
surface
and be under cover. Leaking containers
must be replaced.
Strippers,
chlorinated solvents and flammable solvents are hazardous
waste
and must be stored separately from the waste oil.
a. Waste
oil is normally recycled and must be taken by a
permitted
waste oil transporter. Receipts must be
obtained
and
kept at your facility.
3. Hull
scraping and sanding of paints must be conducted so that
wastes
do not enter surface waters. Collect
scrapings, paint
removal
sludges, sanding dusts and other wastes from paint work
and
dispose of properly. Paint wastes are
generally classified as
hazardous
waste due to the high metal concentrations and/or
biocides
contained in the marine paints.
Therefore, they must be
disposed
of as hazardous waste as described above.
4. Parts
washing may not be done over open ground.
Parts washing
must
be done in a container or parts washer.
The parts can be
rinsed
or air dried over the parts cleaning container. Absolutely
no
fluid, not even rinsewater, can be disposed of to open ground,
storm
drains or septic tank. Research has
shown that this rinse
water
contains solvents, metals, oil and grease.
Dirty parts
washing
fluid must be recycled or disposed of properly as
previously
discussed above. A permitted parts
washing contractor
who
brings new fluid and takes away the sludge and dirty fluid is
the
preferred disposal method.
5. Special
attention should be paid to storm drain locations. Storm
drains
are designed to help alleviate rainwater build-up. These
drains
are not connected to the sanitary sewer system but rather
assist
in allowing rainwater to drain into the ground and
groundwater. Therefore, no discharges are to go to these
storm
drains. Areas nearby storm drains should be kept
free of oil,
grease
and other contaminants so that the rainwater does not wash
these
materials into the storm drains.
6. Solvents
and/or other industrial fluids shall not be discharged
into
septic tanks, storm drains, soakage pits or onto the ground
surface. These fluids must be collected and disposed
of properly.
All
industrial fluids discharged into sanitary sewers must meet
sewer
standards.
7. Used
lead-acid batteries must be sent to a recycler. Batteries
must
be stored on concrete or other impervious surface and under
cover
until shipment.
Pollution
Prevention Suggestions
The
reduction or elimination, at the source, of discharges or
emissions
to the environment.
1. Waste
fluids should be segregated and kept separately. This
prevents
mixing incompatible substances and prevents contamination
of
a non-hazardous waste by a hazardous waste.
This also allows
them
each to be recycled or disposed of appropriately and reduce
disposal
costs.
2. Recycling
of waste fluids is a preferred option.
This can either
be
done on-site or shipped to an approved recycler off-site.
Units
for filtering, adding the necessary additives and restoring
coolant
are available. (Installation of such
units must be
approved
by DERM and the Fire Dept.)
3. For
small to medium facilities, it may be more economical to have
a
parts washer contractor replenish the parts cleaner and remove
the
spent solution, than to install a solvent recycling still.
4. Large
facilities, on-site solvent recycling stills are usually
very
economical with payback periods of only 2-3 years.
5. Alternative
cleaners are available (e.g. special water based
cleaners)
that replace traditional solvent. These
can be used in
a
variety of system including dip tanks, power washers with jet
sprays,
or ultrasonic immersion tanks.
6. Parts
cleaning can be done in 3 stages
1. Preclean
to remove heavier dirt (e.g. with a wire brush)
2. Sink
#1 as an initial sink to do heavier cleaning.
Recycled
only
after full use.
3.
Sink #2 as a final sink for
precision cleaning (used as make-up
for sink #1).
7. Parts
can be removed slowly from solvent sinks and allowed to sit
a
few minutes on "dip racks" which drain back to the sink.
Rollaway
covers that are kept closed when not in use can be used
on
the sink. Sludges should be removed
often and properly
disposed,
but the solution itself can be used many times.
8. Stop
leaks quickly. Drip pans can be placed
to catch leaks. Spot
mopping
with a bucket (and proper disposal of the water) can be
performed. Floor cleaning machines are available that
will spray a
cleaning
solution, scrub with brushed, and vacuum up the solution
(to
be disposed of properly). Absorbent
pads are available that
allow
the oil to be "squeezed out" into a waste oil drum. The pads
can
be reused several times.
9. Scrap
parts can be sold to metal recyclers.
