Our thanks to Tom Hale for this explanation of the Clean Water Act and how it pertains to boats. The hearing to which he refers is the Georgia DNR hearing on wording of HB 201 being held today in Brunswick, GA.

CLEAN WATER ACT

For those who will attend the hearing today. I think it very important that the issue of boat sewage and NDZs is presented clearly and with one voice.

As previously stated, I have been involved with the issues of boat waste discharge and marine sanitation systems with related issues since the 1970s. After being involved with the creation of several No Discharge Zone laws (and always being on the losing end!) I understand that there is a great deal of confusion which then leads to the dissemination of misinformation. NDZs are proposed and established because if the “icky” factor of sewage. When people hear that there is such a thing as “no discharge zones” they assume that that means that anyplace else is a “discharge zones”. And then citizens, Natural Resource types and elected officials get worried about all the boats dumping sewage into “our waters.“ Then with little fore though t or study they decide “We must eliminate this sewage and create a law making it illegal to dump sewage in our waters.” The Georgia law reflects this confusion. It is already illegal to dump raw sewage into the waters of GA or any other territorial waters of the USA. (https://www.epa.gov/vessels-marinas-and-ports/vessel-sewage-frequently-asked-questions)

There is further confusion because the law also states that each vessel must be equipped with a marine sanitation device (MSD) . The word “device” may, to some people, imply that there has to be some sort of mechanical “thing.” Under the law, a sewage holding tank is one such device. Every boat out there today has a marine sanitation device, that being a holding tank (A sewage holding thank is by definition a Type III marine sanitation device.). Every boat out there has the equipment required to be in compliance with the clean water act.

The clean vessel act (https://wsfrprograms.fws.gov/Subpages/GrantPrograms/CVA/CVA.htm) is a program to make funding available for the installation of shore side facilities to handle the waste from boats. In my personal cruising experience Maryland, Rhode Island, Vermont, New York and Massachusetts have done an exemplary job of encouraging commercial facilities to build pump out stations and a number of cities and towns operate mobile pump out boats.

NDZs are created on a state level. To declare a body of water to be an NDZ the state must be able to prove that there are adequate facilities in place to handle the needs of the boating community. A reminder, NDZs only apply to boats which have an onboard treatment system (And, by the way, dumping a bunch of chemicals into your holding tank to kill bacteria does NOT meet the requirements of a sewage treatment system.) Georgia DNR has to understand that declaring all the waters of the state to be an NDZ is unnecessary due to existing federal law. There is no need to duplicate it with a state law. If there are concerns, GA DNR can and should enforce the federal laws already on the books.

The following is from an EPA website on the Clean Water Act.

• Section 312 of the Clean Water Act requires the use of operable, U.S. Coast Guard-certified marine sanitation devices (MSDs) onboard vessels that are equipped with installed toilets and operating on U.S. navigable waters.
• Untreated sewage discharges are prohibited within three miles from shore.
• In order to discharge within three miles, sewage must be treated using a U.S. Coast Guard-approved Type I or Type II MSD. Alternatively, sewage may be stored onboard in a holding tank (Type III MSD).
• Treated and untreated sewage discharges are prohibited in:
  • • Freshwater lakes, reservoirs and other freshwater impoundments whole inlets or outlets are such as to prevent the ingress or egress by vessel traffic.
    • Rivers not capable of navigation by interstate vessel traffic.
    • No-discharge zones (NDZs) (as applicable).
    • In these areas, sewage effluent generally must be retained onboard in a holding tank (Type III MSD). Operators of vessels equipped with flow-through MSDs (Type I or Type II) must secure the device to prevent overboard discharge.
