Industry/Government Activities

Since 1988, the Group has undertaken the bulk of business/industry activities related to natural resource damages policy and practice. In addition, from time to time, various industrial trade groups have also taken an active role, often in collaboration with the Group. Listed below is a description of the Group’s Industry/Trustee NRD Standing Committee aimed at strengthening working relationships between the business/industrial community and governmental authorities (“trustees”).

Committee Background

  • The “NRD Industry/Trustee Standing Committee” was established by the Ad-Hoc Industry Natural Resource Management Group in 1999 in order to provide a focal point and a clearinghouse for communications between the industrial community and government departments and agencies on NRD liability (as defined under CERCLA, the Oil Pollution Act and other laws) and related assessment and restoration issues. The Standing Committee meets 2 or 3 times per year -- in Washington, DC -- and has undertaken a number of joint projects and activities of mutual interest in an effort to encourage practice advancements. Participants in the Committee include a subset of the industrial company members of the multisector Ad-Hoc Industry Natural Resource Management Group. On an invited basis, representatives of five federal natural resource trustee Departments and Agencies (Agriculture, Commerce/NOAA, Defense, Energy, Interior) and representatives from the state trustee and tribal communities participate. Also, on an invited basis, five major business/industry associations (American Chemistry Council, American Petroleum Institute, National Association of Manufacturers, National Mining Association, US Chamber of Commerce) participate. Other private and public entities are sometimes also invited to attend a specific meeting. The Committee provides a mechanism for ongoing dialogue and practice exchange on NRD and allied issues, including remediation of hazardous waste sites, oil spill cleanup, emergency response, prevention, risk assessment, resource restoration and more, as well as a forum for identifying and undertaking collaborative projects and activities, as appropriate, including development of databases, documents and other resources.
