Long-Term Stewardship | Projects

The Long-Term Stewardship project focuses on achieving end-state closure and transition of the river corridor to long-term stewardship. Within the RCCC, key elements of the Long-Term Stewardship work scope include the preparation of Remedial Actions Reports for each CERCLA operable unit, development of a Long-Term Stewardship Plan – Draft that will provide a proposed approach and criteria to be met for long-term stewardship within the river corridor. Results of risk assessment activities, orphan sites evaluations, remedial actions reports, and long-term stewardship plans will provide a basis for closure reviews of the 100 Areas and 300 Area. The independent closure reviews will assure that implemented remedies meet the required action objectives established in the source unit RODs and that no further action is needed to protect human health and the environment. These activities will culminate in development of a Long-Term Stewardship Plan – Final that contains a proposed Finding of Suitability to Transfer in accordance with CERCLA Section 120(h) and the final criteria for long-term stewardship.

Information documenting cleanup and closure activities in the river corridor is maintained in project databases that are managed as part of the Long-Term Stewardship project. Geographical Information Systems (GIS) contain layered spatial information supporting cleanup operations in the river corridor and long-term stewardship. The Stewardship Information System (SIS) contains facility and waste site information for the river corridor including process history, location, dimensions, associated structures and sites, cleanup actions, photos, and references. Direct links to site closeout analytical data are also provided in the database.
