Results of 2000-2006 Marina Project

Workshop Measurement
In an effort to measure compliance and behavioral changes between workshop attendees and non-attendees, a survey Adobe Acrobat Reader Symbolwas conducted of all New Hampshire marinas in 2006.

Workshop Survey Results – 2006
49 marinas attended workshop - 63% responded to survey
40 marinas did not attend workshop - 40% responded to survey

Topics covered by the survey included:

  • Boat washing discharge
    The correct response is to discharge wash water to sewer with permission from local waste water treatment facility or to ground with permit from Department of Environmental Services.
    Marinas that attended workshop – 88% compliant
    Marinas that did not attend workshop – 73% compliant
  • Winterize marine engines
    When preparing engines for winter storage, the pollution prevention recommendation is to drain all fluids from the engine and use antifreeze as a "flush" to remove water. About one cup of antifreeze remains in the engine and will discharge to surface water during the first use in the spring/summer. This is considered "dry" storage. The non-pollution prevention option is to drain the engine, re-plug the lines and outlets, fill the engine with approximately three gallons of antifreeze and store for the winter. This is considered "wet" storage. The three gallons of antifreeze will discharge in the spring/summer during its first use.
    Marinas that attended workshop – 71% of engines are dry stored
    Marinas that did not attend workshop – 31% of engines are dry stored
  • Shrink wrap
    During the fall in New England, a common storage practice is to shrink wrap boats to protect them from water and snow damage. The plastic wrap is recyclable but can not be recycled through traditional waste channels, such as local transfer stations or with other plastic waste.
    Marinas that attended workshop – 42% recycle shrink wrap=42,660 lbs
    Marinas that did not attend workshop – 27% recycle shrink wrap=2,880 lbs
  • Used oil
    Used oil generated at the marina should either be recycled by an authorized facility or burned on-site for energy recovery.
    Marinas that attended workshop – 91% compliant
    Marinas that did not attend workshop – 36% compliant

Conclusion
By comparing the two groups, we determined if a marina attended a workshop, the marina would have a higher compliance rate and were more likely to implement best management practices to preserve water quality in New Hampshire.

Best Management Practices Manual Measurement
In an effort to evaluate improved environmental compliance and behavioral changes implemented as a result of the 2001 best management practices manual, a BMP follow-up survey was distributed to all New Hampshire marinas.

Survey responds indicate various changes and improvements:

  • 86% of survey responders:
    • Label used oil tanks and drums "Used Oil for Recycle".
    • Deliver used oil to authorized burner or marketer.
    • Drain oil filters two to three days to recover free-flowing oil.
  • 71% of survey responders:
    • Provide reusable cloth wipes to clean parts and absorb small spills.
    • Store, label and recycle used fluorescent bulbs properly.
  • 57% of survey responders:
    • Switched from solvent-based to aqueous-based parts washer or removed washer from the facility.
    • Place absorbent socks in engine test tanks to remove contaminants.
