What is the Clean Vessel Act?
Congress passed the Clean Vessel Act in 1992 (CVA) to help reduce pollution from vessel discharges.

  • Why should I worry about boat sewage?

  • No one wants to take a swim where they know there is raw sewage from boats.

  • No one wants to eat raw shellfish that could be contaminated. We all hear a lot about pollution in our water, but what can we, as individuals, do about pollution?

  • Properly managing sewage on our boats is something everyone can do right now to help improve local water quality.
