From 12/12/03 Memorandum:
"In an effort to improve performance measurement reporting, OECA is pleased to provide the attached guidance on estimating environmental benefits from concluded enforcement actions for the Superfund and RCRA Corrective Action programs. This new document provides guidance for the “Volume of Contaminated Medium Addressed”(VCMA), which for remediation programs more accurately reflects both the magnitude and nature of an environmental problem addressed by an enforcement action than does a measure of the mass of pollutants reduced. As evidenced from Regional comments on the July 2003 proposal for estimating pollutant reductions resulting from Superfund and RCRA Corrective Action enforcement actions, all Regions are supportive of the VCMA approach.
The attached document provides a brief background on the measure, describes the rationale for the new volume-of-contaminated medium basis for the measure, and identifies the methodologies that should be used to estimate the Volume of Contaminated Medium Addressed for various Superfund and RCRA Corrective Action response actions."
Note: The new filters in ICIS no longer allow the unit: 1,000 cubic yards. Therefore, the volume to be reported for groundwater response actions is cubic yards, not 1,000 cubic yards as shown in protocol 2 of the attached guidance. Therefore, please ignore the last part of step 5 in the "Methodology for calculating the measure" section of protocol 2 (i.e., do not "divide by 1000 to get the reporting volume in 1000s of cubic yards.")
