Marina Management Measures
The 1993 guidance for the Coastal Nonpoint Program specifies 15 management measures for marinas grouped under two broad categories:
1. Siting and Design
- Marina Flushing
- Water Quality Assessment
- Habitat Assessment
- Shoreline Stabilization
- Storm Water Runoff Management
- Fueling Station Design
- Sewage Facility Installation
2. Operation and Maintenance
- Solid Waste Management
- Fish Waste Management
- Liquid Material Management
- Petroleum Control
- Boat Cleaning
- Public Education
- Sewage Facility Maintenance
- Boat Operation
In 2001, EPA updated the original coastal marina management measures into national guidance on the best available, economically achievable means of reducing pollution of surface water runoff from marinas and recreational boating National Management Measures to Control Nonpoint Source Pollution from Marinas and Recreational Boating.
MARINA SITING AND DESIGN
Site and design marinas such as tides and/or currents will aid in flushing of the site or renew its water regularly.
Site and design marinas to protect against adverse effects on shellfish resources, wetlands, submerged aquatic vegetation, or other important riparian and aquatic habitat areas as designated by local, state, or federal governments.
Where shoreline erosion is a nonpoint source pollution problem, shorelines should be stabilized. Vegetative methods are strongly preferred unless structural methods are more cost effective, considering the severity of wave and wind erosion, offshore bathymetry, and the potential adverse impact on other shorelines and offshore areas.
Implement effective runoff control strategies which include the use of pollution prevention activities and the proper design of hull maintenance areas. Reduce the average annual loadings of total suspended solids (TSS) in runoff from hull maintenance areas by 80 percent. For the purposes of this measure, an 80 percent reduction of TSS is to be determined on an average annual basis.
Design fueling stations to allow for ease of spill cleanup.
MARINA AND BOAT OPERATION AND MAINTENANCE
Properly dispose of solid wastes produced by the operation, cleaning, maintenance, and repair of boats to limit entry of solid wastes to surface waters.
Promote sound fish waste management through a combination of fish-cleaning restrictions, public education, and proper disposal of fish waste.
Provide and maintain appropriate storage, transfer, containment, and disposal facilities for liquid material, such as oil, harmful solvents, antifreeze, and paints, and encourage recycling of these materials.
Reduce the amount of fuel and oil from boat bilges and fuel tank air vents entering marina and surface waters.
For boats that are in the water, perform cleaning operations to minimize, to the extent practicable, the release to surface waters of (a) harmful cleaners and solvents and (b) paint from in-water hull cleaning.
Public education/outreach/training programs should be instituted for boaters, as well as marina owners and operators, to prevent improper disposal of polluting material.
Ensure that sewage pumpout facilities are maintained in operational condition and encourage their use.
Restrict boating activities where necessary to decrease turbidity and physical destruction of shallow-water habitat.
