Which document records the chosen remedy after evaluating CERCLA remedial options?

• A. ROD
• B. CMS
• C. RD/RA
• D. Phase I Site Reconnaissance

Answer: (A)

The document that records the chosen remedy after evaluating remedial options is the Record of Decision. In CERCLA, the process after the Remedial Investigation/Feasibility Study weighs different cleanup options against criteria such as protectiveness, compliance with applicable or relevant and appropriate requirements, long-term effectiveness, implementability, and cost. After a preferred remedy is identified and publicly reviewed, the final decision is documented in the Record of Decision. This document explains which remedy was selected, the rationale for that choice, the cleanup standards to meet, and how the remedy will be implemented and monitored over time.

The other items fit different stages or aspects of the process: Remedial Design/Remedial Action is the phase that actually designs and implements the remedy; Phase I Site Reconnaissance is an initial site assessment; and CMS (where used) generally refers to a study used to evaluate corrective measures, not the final decision document under CERCLA.
