In correspondence dated September 9, 2009, the USEPA approved the Final Feasibility Study (FS) for PICA 001, 006, 022, 085, 143, 146, 163, 171, 192, and 199.  Revisions submitted by the Army

were deemed to be acceptable but for one response relating to the frequency of monitoring and assessment of well selection.  The monitoring frequency and well selection were to have been

assessed as part of the FS but were not.  The USEPA assumed that the missing information will be documented in the remedial design.

In correspondence dated December 3, 2009 the USEPA approved the Long-Term Monitoring Plan and Land Use Control Remedial Design for Area C Groundwater.
