Acronym Description
RAGS Risk Assessment Guidance
Part A of RAGS describes how to conduct a site-specific baseline risk assessment. The information in Part A is necessary background for Part D. Part B provides guidance for calculating risk-based concentrations that may be used, along with applicable or relevant and appropriate requirements (ARARs) and other information, to develop preliminary remediation goals (PRGs) during project scoping. PRGs (and final remediation levels set in the Record of Decision) can be used throughout the analyses in Part C to assist in evaluating the human health risks of remedial alternatives. Part D complements the guidance provided in Parts A, B, and C and presents approaches to standardize risk assessment planning, reporting, and review. Part D guidance spans the CERCLA remedial process from project scoping to periodic review of the implemented remedial action. Part D guidance applies to all Superfund Risk Assessments starting after January 1, 1998.   back to top...

Remedial Design (RD) is the phase in Superfund site cleanup where the technical specifications for cleanup remedies and technologies are designed.

The RD/RA is based on the specifications described in the record of decision (ROD).   back to top...
RI/FS Remedial Investigation/Feasibility Study
After a site is listed on the NPL, a remedial investigation/feasibility study (RI/FS) is performed at the site. The RI serves as the mechanism for collecting data, while the FS is the mechanism for the development, screening, and detailed evaluation of alternative remedial actions. The RI and FS are conducted concurrently. Data collected in the RI influence the development of remedial alternatives in the FS, which in turn affect the data needs and scope of treatability studies and additional field investigations.   back to top...
RMP Risk Management Plans
Facilities are required to submit risk management plans (RMP) to EPA. Risk management plans will be available to State and local governments and citizens to help them understand potential local chemical hazards and take steps to prevent accidents. The risk management program is administered by EPA's Chemical Emergency Preparedness and Prevention Office (CEPPO).   back to top...
ROD Record of Decision
The Record of Decision (ROD) is a public document that explains which cleanup alternatives will be used to clean up a Superfund site. The ROD for sites listed on the NPL is created from information generated during the RI/FS.   back to top...
