The Environment and Natural Resources Division recently announced a natural resource damage (NRD) settlement with the city of Seattle, Washington, to resolve its liability for injured natural resources at the Lower Duwamish Waterway Superfund Site by funding restoration projects. Unlike previous NRD settlements, this one uses a new, market-based mechanism to achieve restoration.. Under the new approach, highly credible restoration project development companies design and construct approved restoration projects, then sell credits in those restoration projects to liable parties. Liable parties can then use purchased restoration project credits to satisfy NRD liability. Although this innovative approach will not be available in every case, it provides another option for parties to consider when resolving a case involving natural resource damages.
