How often do I have to do a VGP test?

The US EPA requires vessels to test the ballast water twice per year. Unless the sampling results are within permit limits for two consecutive events. In that case, monitoring may be reduced to one time per year.

What is the Vessel General Permit?

Vessels sailing on the USA have to comply with the regulations for the 2013 Vessel General Permit (VGP). This will be replaced by the Vessel Incidental Discharge Act (VIDA) in the near future.
