The Vessel General Permit (VGP) is a permit issued by the US Environmental Protection Agency (EPA) that regulates discharge water incidental to the normal operational conditions of commercial vessels greater than 79 feet in length, which are entering and/or operating in all US territorial waters.
The VGP includes general effluent limits applicable to all covered discharges as well as general effluent limits applicable to 27 specific discharge streams in addition to narrative water-quality based effluent limits, inspection, monitoring, recordkeeping, reporting requirements and additional requirements applicable to certain vessel types.
In this light Maritec provides a one-of-kind all-encompassing Annual Program to assist vessels voyaging into US territory waters stay on top of their entire VGP requirements for discharge waters in the areas of Ballast Water Treatment, Scrubber Water treatment, Bilge Water treatment, and Gray Water Treatment.
SCOPE & BENEFIT OF OUR ANNUAL PROGRAM
Maritec’s unique one-stop solution helps you meet your Discharge Water Compliance requirements as per VGP 2013.
