The corrective action process under RCRA is similar to that under CERCLA. It generally consists of the following three steps:
- RCRA facility investigation (RFI) — An RFI is similar to a CERCLA remedial investigation and includes the assessment of both active and inactive solid waste management units. The RFI identifies releases that require corrective action when contamination levels exceed action levels established under the state regulations.
- Corrective measures study (CMS) — A CMS has an objective similar to that of a feasibility study under CERCLA; it is intended to evaluate appropriate cleanup alternatives for eliminating or reducing the risks posed by releases discovered during the RFI.
- Corrective measures implementation (CMI) — The CMI phase involves constructing and operating the remedy (or remedies) selected after completion of the CMS.
