Gray water testing

Product description

Final 2013 VGP specifies that new building vessels constructed on or after December 19, 2013 and with a maximum crew capacity greater than or equal to 15, and providing overnight accommodations to those crew are required to collect samples of gray water discharge for analysis.

For these vessels, the Final 2013 VGP requires two samples a year to be collected, at least 14 days apart, and analyzed for the following:
• Biological Oxygen Demand (BOD)
• Fecal Coliform or E. coli
• Total suspended solids
• pH
• Total residual chlorine

The commingled discharge of graywater mixed with sewage from vessels must comply with the effluent limits for graywater discharge. Though not a requirement of this permit, vessel owner/operators are advised that all discharges commingled with sewage must meet the requirements set forth in section 312 of the CWA and its implementing regulations found at 40 CFR Part 140 and 33 CFR Part 159. Hence, discharges of graywater mixed with sewage must meet both standards to be in compliance with the CWA.
