Larger FUSRAP sites undergo several steps that lead to cleanup. First, information about the site is collected and reviewed. Then, a remedial investigation/feasibility study is conducted. The remedial investigation is made to identify the type and location of the contamination. The feasibility study develops and evaluates cleanup alternatives.
Throughout the remedial investigation/feasibility study process, the public is informed about the progress toward a decision on the cleanup alternative.
When a cleanup alternative is chosen, a proposed plan is written to explain why it was chosen. Members of the public are asked to comment on all the cleanup options, including the selected alternative. After public comments are considered, a final decision is made and documented in a record of decision. The remedial design follows the record of decision and includes technical drawings and specifications that show how the cleanup will be conducted.
Cleanup begins after the remedial design is complete. This phase involves site preparation and construction activities. When these activities are completed, verification surveys are conducted to ensure that cleanup objectives for the site have been met.
Smaller FUSRAP sites undergo a somewhat different review and documentation process. Taking the place of a remedial investigation/feasibility study and proposed plan, are:
- A site radiological characterization, a more detailed version of the preliminary radiological assessment.
- An engineering evaluation/cost analysis (EE/CA), which lists the range of cleanup options available and identifies the DOE's preferred option.
- An action memorandum, authorizing a cleanup to proceed.
The public has the opportunity to review and comment on the site EE/CC.Under special circumstances, a site cleanup may proceed without the issuance of an EE/CA -- proceeding directly from characterization to cleanup.
