VCMA measure time period

"The volume of contaminated medium measure includes the total volume of medium anticipated (as of the enforcement action or settlement necessitating the CCDS)  to be addressed by the response action at its completion.  As an example, if a Superfund record of decision requires cleanup of the groundwater plume to MCLs, then the total volume of aquifer presently above MCLs is what is reported; this is what will be addressed at the completion of the cleanup.


This is a change from the previous requirement to report the first year’s worth of pollutant reduction data once the response action or corrective active had been fully implemented."
