Text Box: This removal action started in December 2009 with munitions and
 explosives of concern (MEC) being first detected on January 20, 2010.  Prior to that only uncovered munitions debris and metal debris unrelated to MEC were detected. Eventually this removal action was assigned a higher priority when

Newest tilcon removal action (cont’d from p. 1)

it was learned that Tilcon’s commercial operations would eventually be directed toward the area where soil had been stockpiled. This action resulted in the following MEC detections:


  • January 20, 2010 a “BD FUZE MK23” was detected and scheduled for detonation.

 February 11, 2010 a 5-inch HE (High Explosive) projectile was uncovered. It is expected to be disposed offsite.


  • Two other 5-inch rounds were detected – the most recent of which was on February 17, 2010.

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.
