Five Year Reviews
Section 121 of CERCLA, as amended by SARA, requires that remedial actions which result in any hazardous substances, pollutants, or contaminants remaining at the site be subject to a five-year review. The NCP further provides that remedial actions which result in any hazardous substances, pollutants, or contaminants remaining at the site above levels that allow for unlimited use and unrestricted exposure be reviewed every five years to ensure protection of human health and the environment.
EPA Five Year Review Report Available: Bunker Hill Superfund Site November, 2010
EPA has completed its third Five Year Review (PDF) (464 pp, 14.5MB) of the Bunker Hill Superfund Site. During the review, cleanup actions were evaluated at the site’s three “operable units:” the Bunker Hill “Box” populated areas, the Box non-populated areas, and the Coeur d’Alene Basin. Overall, EPA has found that cleanup actions are functioning as expected and are protecting human health and the environment in most locations where actions have been taken.
