Portland Harbor & Columbia Slough

Environmental Compliance has represented Potentially Responsible Persons (“PRPs”) at both the Portland Harbor and Columbia Slough “Superfund Sites”.  In one case we substantially reduced the “equitable allocation” to our client by differentiating (by toxicity and dispersal) between the hazardous substance our client discharged (a heavy metal) from those discharged by other parties (primarily chlorinated organics like dioxin).  In another case we proved that our client contributed nothing at all to a nearby release of hazardous substances.  We have also been very successful at reducing our clients’ shares of response costs by bringing in Responsible Persons who had previously gone unidentified by the government, even at so-called “orphan” sites.
