What’s Required?

  • The VGP usually incorporates existing USCG requirements in those areas (blackwater, graywater, ballast water, bilge water, etc.) where the USCG traditionally regulates ships.

  • The VGP contains a narrative requirement to meet water quality standards.

  • The VGP contains technology-based effluent limits for just about all vessel discharges except for blackwater.

  • Blackwater is not covered because CWA § 502(6) leaves vessel sewage out of the definition of pollutant and CWA § 312 gives authority to regulate vessel sewage to the Coast Guard.

  • The VGP specifies open ocean exchange as the standard requirement for ballast water management until the numeric ballast water discharge limits in VGP Part become effective in accordance with the schedule in

  • The VGP regulates ballast water management during coastal voyages and management of ballast tank sediments more stringently than current Coast Guard requirements.

  • The VGP regulates 26 types of discharges including deck runoff, deck and hull washdown, bilgewater, ballast water, hull coating leachate and underwater hull cleaning, fire fighting foam, boiler blowdown, cathodic protection, chain locker effluent, hydraulic and lubricating fluids, desalinization brine, exhaust scrubber wastewater, graywater and graywater with sewage, and others.

  • The VGP contains class-specific requirements for large cruise ships, medium cruise ships, large ferries, barges, oil tankers, and research vessels.
