US 2013 Vessel General Permit VGP Ballast Water Sampling Analysis Requirements
In their latest alert to their clients, ECM Maritime Services, LLC reports on clarification received from the EPA relating to the requisite frequency of sampling and analysis of treated ballast water discharges from USCG type approved Ballast Water Treatment Systems (BWTS) and Alternate Management systems (AMS)* onboard vessels subject to VGP requirements.
In brief, vessels with BWTS using chemical biocide will need to comply with (a) and (b) below while vessels with BWTS not using chemical-based treatment methods need only comply with (a) below.
a) Effluent Biological Organism Monitoring (VGP Part 184.108.40.206.1.1.4)
b) Residual Biocide and Derivative Monitoring (VGP Part 220.127.116.11.18.104.22.168)
Where applicable, the requirements under (a) and (b) must be conducted two times during the first year. If the sampling results for (a) are below VGP limits both times, effluent biological organism monitoring can be reduced to once per year in subsequent years. If the sampling results for (b) are below VGP limits both times, residual biocide and derivative monitoring must nevertheless still be performed twice per year in subsequent years. Members are recommended to take note of this clarification to avoid falling foul of these VGP requirements.
