US Coast Guard

Vessels sailing in U.S. waters will be required to comply with USCG ballast water discharge standards and the USEPA Vessel General Permit (VGP), in   addition to State ballast water regulations.

The USCG’s final rule is a ballast water discharge standard which is essentially   the same as that adopted by the IMO in 2004. In addition, the USEPA 2013 Vessel General Permit has adopted numeric limits within the permit that also align with the USCG rule.
