During the course of normal marina operations,
various activities and locations in the marina can generate polluting
substances. Such activities include waste disposal, boat fueling, and
boat maintenance and cleaning; such locations include storage areas
for materials required for these activities and hull maintenance areas
(METRO, 1992a; Tobiasson and Kollmeyer, 1991). Of special concern are substances that can be toxic to
aquatic biota, pose a threat to human health, or degrade water
quality. Paint sandings and chippings, oil and grease, fuel,
detergents, and sewage are examples (METRO, 1992a; Tobiasson and
Kollmeyer, 1991).
It is important that marina operators and patrons
take steps to control or minimize the entry of these substances into
marina waters. For the most part, this can be accomplished with simple
preventative measures such as performing these activities on protected
sites, locating servicing equipment where the risk of spillage is
reduced (see Siting and Design section of this chapter), providing
adequate and well-marked disposal facilities, and educating the
boating public about the importance of pollution prevention. The
benefit of effective pollution prevention to the marina operator can
be measured as the relative low cost of pollution prevention compared
to potentially high environmental clean-up costs (Tobiasson and
Kollmeyer, 1991).
For those planning to build a marina, attention to
the environmental concerns of marina operation during the marina
design phase will significantly reduce the potential for generating
pollution from these activities. For existing marinas, minor changes
in operations, staff training, and boater education should help
protect marina waters from these sources of pollution. The management
measures that follow address the control of pollution from marina
operation and maintenance activities.
A. Solid Waste Management Measure
Properly dispose of solid wastes produced by the
operation, cleaning, maintenance, and repair of boats to limit entry
of solid wastes to surface waters.
This management measure is intended to be applied by
States to new and expanding marinas. Under the Coastal
Zone Act Reauthorization Amendments of 1990, States are subject to a
number of requirements as they develop coastal nonpoint source
programs in conformity with this measure and will have some
flexibility in doing so. The application of management measures by
States is described more fully in Coastal Nonpoint Pollution
Control Program: Program Development and Approval Guidance,
published jointly by the U.S. Environmental Protection Agency (EPA)
and the National Oceanic and Atmospheric Administration (NOAA) of the
U.S. Department of Commerce.
Marina operators are responsible for determining
what types of wastes will be generated at the marina and ensuring
proper disposal. Marina operators are thus responsible for the
contents of their dumpsters and the management of solid waste on their
property. Hazardous waste should never be placed in dumpsters. Liquid
waste should not be mixed with solid waste but rather disposed of
properly by other methods (see
Liquid Waste Management Measure).
This measure was selected because marinas have shown
the ability to minimize the entry of solid waste into surface waters
through implementation of some or all of the practices. Marinas
generate a variety of solid waste through the activities that occur on
marina property and at their piers. If adequate disposal facilities
are not available there is a potential for disposal of solid waste in
surface waters or on shore areas where the material can wash into
surface waters. Marina patrons and employees are more likely to
properly dispose of solid waste if given adequate opportunity and
disposal facilities. Under Federal law, marinas and port facilities
must supply adequate and convenient waste disposal facilities for
their customers (NOAA, 1988).
As discussed more fully at the beginning of this
chapter and in Chapter 1, the following practices
are described for illustrative purposes only. State programs need not
require implementation of these practices. However, as a practical
matter, EPA anticipates that the management measure set forth above
generally will be implemented by applying one or more management
practices appropriate to the source, location, and climate. The
practices set forth below have been found by EPA to be representative
of the types of practices that can be applied successfully to achieve
the management measure described above.
a. Perform boat maintenance/cleaning above the
waterline in such a way that no debris falls into the water.
b. Provide and clearly mark designated work areas
for boat repair and maintenance. Do not permit work outside designated
areas.
c. Clean hull maintenance areas regularly to remove
trash, sandings, paint chips, etc.
Vacuuming is the preferred method of collecting
these wastes.
d. Perform abrasive blasting within spray booths or
plastic tarp enclosures to prevent residue from being carried into
surface waters. If tarps are used, blasting should not be done on
windy days.
e. Provide proper disposal facilities to marina
patrons. Covered dumpsters or other covered receptacles are preferred.
While awaiting transfer to a landfill, dumpsters in
which items such as used oil filters are stored should be covered to
prevent rain from leaching material from the dumpster onto the ground.
f. Provide facilities for the eventual recycling of
appropriate materials.
Recycling of nonhazardous solid waste such as scrap
metal, aluminum, glass, wood pallets, paper, and cardboard is
recommended wherever feasible. Used lead-acid batteries should be
stored on an impervious surface, under cover, and sent to or picked up
by an approved recycler. Receipts should be retained for inspection.
