The purpose of this handbook is to give Bureau of Land Management (BLM) and USDA Forest Service (Forest Service) employees a general overview of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process and provide data so that the costs involved with the investigation, removal or remediation of wastes, and reclamation of sites on BLM and Forest Service property can be estimated.
