Remedial Design. Plans, specifications, and other documents necessary to
construct or implement the remedy are developed during remedial design (RD), an engineering
phase that precedes the RA. The specifications are based upon the detailed descriptions of the
selected remedy and the remediation/cleanup criteria provided in the ROD.
e.
Remedial Action. The RA is the implementation of the selected remedy from the
ROD and the RD. RA activities must conform to the remedy set forth in the ROD and other
post-ROD decision documents (e.g., ROD amendments, explanation of significant differences).
The remedial action includes the completion of an operational and functional (O&F) period
(Paragraph 2-2.a), if necessary, followed by any long-term response action (LTRA) for
groundwater or surface water remedies (Paragraph 2-2.a), prior to long term operation and
maintenance (O&M) of the remedy.
