When the Environmental Protection Agency (EPA) threatened to put shipyards in the Coos Bay Estuary on the National Priorities List of hazardous waste sites, the Charleston Marina Complex, in Coos Bay, Ore., responded quickly. The EPA and Oregon Department of Environmental Quality (DEQ) determined that the area surrounding the complexs Charleston Boatyard was contaminated with heavy metals, poly-aromatic hydrocarbons and tributyl tin.
The agencies issued
a consent order requiring development and implementation of an action plan.
With the help of a multi-disciplinary team, a combination of source controls,
and a passive stormwater treatment system, the Complex met the agencies
terms and reduced pollutant levels in stormwater runoff to be compliant
with its permit requirements.
