The following are annotated versions of the checklists developed by the Clean Marina programs of Maryland and Virginia, used to guide marina operators through the process of certification in the states' very similar programs. The numbered items are the actual checklist questions, with anywhere from five to 16 questions in each category. The states have slightly different arithmetic for the minimum number of "yes" answers required to pass. Maryland has a minimum percentage for each category (e.g., 85% in Vessel Maintenance and Repair, but 70% in Marina Design and Maintenance). Virginia simply requires an 80% score overall, as long as all legal requirements are met. The bulleted items after the numbered questions are summarizes of the information found in each states' Clean Marinas guidebook. Checklist items in italics are those that are required by law-i.e., required even for non-certified marinas.

For more detailed information on any of the checklist questions, you may read or download the state guidebooks at and

scrap metal exemption (if the scrap metal recycler takes them) 

All other containers: 

All material that can be removed has been. Containers that held compressed gas are at atmospheric pressure.Containers that held acute hazardous waste have been triple rinsed with the appropriate solvent. Properly dispose of solvent 

Residue from sanding, scraping, and blasting 

Document that the residue is not hazardous (no metals). 

Dispose of as a solid waste. If it contains metals, 

it is a hazardous waste and must be disposed of properly. 

Pressure washing residue 

Dispose of as solid waste 

Lead Batteries 

Recycle or sell to scrap dealers. 

Store on an impervious surface, under cover. 

Protect from freezing. Check frequently for leakage. 

Inform boaters that if they bring their old battery to a dealer, they will receive a partial refund on a new battery. 

Expired distress signal flares 

Encourage boaters to keep on board as extras. 

Store in a marked, fire safe container. 

Use expired flares to demonstrate to boaters how they are used. 

Notify the Coast Guard and fire department of a demonstration. 

Bring flares to a local fire department or household hazardous waste collection program. 

Scrap metal 


Light bulbs: fluorescent, mercury vapor, high & low pressure sodium, metal halide

Recycle if you have more than a few. 

Treat as a solid waste if you have less than two and 

they're mixed with other solid waste. If you segregate from solid waste they need to be 

dealt with as a hazardous or universal waste.


Recycle. If you deal with AC, you must be certified and use 

EPA approved CFC recovery and recycling equipment. 

Use alternative refrigerants: HCFC-22, HCFC-123, HFH 134A 

NOTE: do not mix refrigerant oil with used engine oil and 

do not mix it with engine oil to be burned in space heaters. 

Monofilament Fishing Line 

Recycle through a manufacturer or tackle shop. 

Dispose in sealed trash can. 

Scrap tires 

Recycle-legally you can't store tires without a permit- 

over 500 is Class 6 felony 


Dispose of as hazardous waste 

Plastic Shrink Wrap 


Fish Waste 

Prohibit disposal of fish waste into confined marina waters. 

Establish a fish cleaning station with one of the 

following disposal methods: 

Implement fish composting where appropriate 

Use a grinder to make chum at your marina store 

Arrange for crabbers to take fish carcasses 

Abandoned and derelict vessels 

Ensure holding tanks, fuel tanks and bilges are not leaking 

Haul out boats that are sinking/have sunk 

Contact the owner 

Obtain title to the boat before attempting to dispose of vessel 

VII. Vessel Maintenance and Repair

Restrict maintenance activities to designated work areas at least 100 feet from shore.

Clearly mark work areas with signs.

Contain dust from sanding/use vacuum sanders.

Perform blasting only in enclosed structure.

Contain and manage wastewaters from pressure washing activity.

All pollutants must be removed from wash water before discharging it. At the minimum, allow large particles to settle out of the water.  If detergents were used in washing, waste water must be discharged into the sewer system.  Use filtration, chemical treatment, or swirl concentrators to remove particles; or reuse wash water.

Prohibit in-water pressure washing and hull scraping.

Pressure wash over a bermed, impermeable surface that allows waste water to be contained and filtered.

Paint over tarps or other impervious surface.

Conduct engine repair and maintenance over impervious surface.

Do not wash engine parts over the bare ground or water.

Recommend bottom coatings with minimal environmental impact.

Avoid soft ablative paints and use water-based paints whenever possible.

Handle solvents appropriately.

Use only the minimal amount of solvent needed for a job; reuse and recycle solvents when possible; keep records of solvent usage. 

Use propylene glycol antifreeze for all systems during winterization.

Never use ethylene glycol in potable water systems.

VIII. Stormwater 

Have a stormwater management pollution prevention plan.

Some plan requirements may be:

Used oil management

Spent solvent management

Proper disposal of spent abrasives

Disposal of vessel wastewater

Spill prevention and control

Safe fueling procedures

General good housekeeping

Appropriate painting and blasting procedures

Used battery management

Store potentially harmful materials under cover.

Limit the use of chemicals with integrated pest management.

Minimize impervious areas.

Only pave areas where it is absolutely necessary; minimize the length of roadways needed for new or expanding marinas; plan roads in order to avoid crossing sensitive areas such as tidal wetlands; consider alternatives to asphalt such as dirt, gravel, seashells and engineered porous pavement.

IX. Habitat and Species

Practice proper cleaning techniques for transporting trailered boats.

Inspect areas where water can be trapped (bilges) and drain these areas before each trip; empty boat of trash, wash and dry boat and trailer before and after each trip.

Post no-wake signs where shoreline erosion is a problem.

Practice water-wise landscaping.

Water plants only when they indicate they are thirsty, by wilting or lying flat.

Choose plants that are suited to the existing conditions.

Water deeply and infrequently rather than lightly and often.

Use equipment that delivers water prudently, such as sprinklers for lawns and soaker hoses or drip irrigation for shrubs, flowers, and vegetables.

Place mulch to a depth of three to four inches around plants and plant groundcovers at the base of trees.

Group plans with similar water needs together.

Replace lawn areas with wildflowers, groundcover, shrubs and trees.

Recycle gray water (water that has been used once) for watering landscaped areas.  Also collect rainwater and use for this purpose.

Incorporate integrated pest management.

Use the least toxic methods for pest management.  Purchase the least toxic chemical in the smallest amount needed.

Do not use pesticides before rainfall or on a windy day. Do not apply near water.

Apply insecticides in the evening.

Choose disease and insect resistant plants.

Mow lawn areas to suppress weeds  (to no less than 2.5 inches for cold-weather grass and no less than 1.5 inches for warm weather grass).

Pull weeds by hand so herbicides are less necessary.

Be more tolerant of weeds and pests.

Foster natural predators such as spiders, praying mantis, dragonflies, lacewings, soldier beetles, birds, bats, frogs, lizards and certain snakes and toads.

Use natural agents such as milky spore disease to control grubs and Japanese beetles, Bacillus thuringiensis for mosquitos and small moth larvae and sabadilla for clinch bugs.

Treat only serious or threatening pest infestations.

Develop and maintain vegetated areas.

Plant vegetated areas with plants that require minimal care such as native plants.

Choose perennial plants instead of annuals.

Compost leaves, branches, grass trimmings and other organic matter.

Plant vegetation filters to slow surface water runoff.

Choose plants that bear flowers, fruit, nuts and seeds.

Maintain proper soil pH and fertility levels.  Submit a soil sample to your local Agricultural Cooperative Extension Agent to determine these levels and application rates for soil amendments.

Foster beneficial organisms with vegetated areas such as earthworms.

Practice habitat and species restoration.

Post guidelines for responsible vessel operation around wildlife.

Include instruction to:

Stay away from animals, and when moving close to them is necessary because of channel markers, maintain a set speed and course.

Never surround animals or circle animals or nests with vessels.

Avoid sensitive habitats such as the shallow water around marshes and submerged vegetation.

When observing animals, approach them slowly from the side, idle slowly or stay in neutral and maintain a set course. Do not chase animals if they leave the area, and limit observation time to 15 minutes or less.

X. Boater Education

Give clean boating tip sheets to your boaters.

Distribute VA Clean Boater program information

Provide clear signage around your marina.

Post environmental signs in a highly visible area.

Encourage patrons to review contracts.
