Ballast water Regulations
“This will reduce the risk of contamination by new organisms,” explains Researcher Stephanie Delacroix at the Norwegian Institute for Water Research (NIVA).
The IMO convention on the treatment of ballast water was adopted in 2004. It prohibits ships from discharging ballast water within certain distances from specified coastal zones. When the IMO Ballast Water Management Convention will be ratified, this ballast water will also have to be disinfected by certified equipment before being released.
First international authorised land-based full scale testing facility
Such equipment can only be approved after exhaustive testing in accordance with stringent regulations. NIVA’s Marine Research Station at Solbergstrand in the narrow Drøbak Sound, a little south of Oslo, became the first internationally authorised full scale testing facility for both marine water and brackish water in 2005.
Tests are implemented at Solbergstrand in small scale as well as in huge tanks with capacities for several hundred cubic metres of water. Researchers from NIVA also perform shipboard testing before final equipment authorisation can be granted.

Summary recently issued a final rule intended to reduce the importation of invasive species into the United States, which is estimated to cost the United States billions of dollars each year. See Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. Waters, 77 Fed. Reg.17254 at 17301 (March 23, 2012) (the “Rule”), to be codified at 33 CFR Part 151 and 46 CFR Part 162. The Rule applies to U.S. and foreign ships calling at U.S. ports and sets out the federal ballast water management regulations pursuant to the National Aquatic Nuisance Prevention Control Act (NANPCA) and the National Invasive Species Act (NISA). (Note that each state is entitled to impose more stringent requirements pursuant to the Clean Water Act (CWA).) In general, the Rule requires ship owners/operators to install, operate and maintain a USCG-approved ballast water management system (BWMS) to satisfy the treatment standards for living organisms (e.g., invasive aquatic species, bacteria and other pathogens) in ballast water as specified by the Rule.
