Task Code
Monthly EFR

UST Board Approval Date - 2/2/05

Enhanced Fluids Recovery (EFR) is defined as total fluids extraction, i.e. extraction of soil vapor gas, groundwater and non-aqueous phase liquid (NAPL) or some combination of the three. EFR consists of applying vacuum, generally greater than 15 inches of mercury, to a wellhead to enhance the flow and recovery of petroleum fluids from a well(s) so that they can be removed and recovered from the subsurface. It is generally appropriate for NAPL recovery from small isolated contaminated areas.

Expenses incurred with respect to performing EFR remediation may be claimed for multiple events in a month. The task maximum applies to the Monthly total. All labor to plan, coordinate and conduct the event(s), including travel time, is included in the task maximum. All equipment and miscellaneous materials involved in completing the EFR event (all trucks, blowers, pumps, treatment devices, etc.) are to be included in the task maximum under Monitoring devise such as PIDs, LEL meters, multi-meters, etc. are to be included in the task maximum under

When EFR remediation has been implemented as part of a Phase IV Remedy Implementation Plan, the number of EFR events is unlimited. The Phase III Remedial Action Plan shall document the appropriateness and cost benefit of EFR in accordance with 310 CMR 40.0850 and 40.0860 when compared to other available technologies. Costs associated with such evaluations shall be reimbursed in accordance with task codes 2.6 (Phase III) and 2.12.4 (Feasibility of Permanent Solutions; Feasibility of Restoration to Background).

When EFR is implemented as part of an IRA or RAM (i.e., not Phase IV), the number of EFR events is limited to the task maximum of 2 events per month, for up to a total of six months. After six months of EFR events have been conducted, a cost benefit analysis using data from the completed events shall be prepared and submitted with the reimbursement application to determine if EFR should be continued or if an alternative petroleum remediation technique should be employed. Charges for the cost benefit analysis shall be claimed under task code 15, Remediation Feasibility Studies (Net Present Value).
