POSSIBLE DEMOLITION SITE

 

SITE DESCRIPTION

This Possible Demolition Site MRS encompasses 40 acres (increased from 15 acres) plus an unknown number of acres north of K Road, but was not identified as an active US Army MMRP site in the Final CTT Range/Site Inventory Report (USACE 2003). The historical records review (HRR) findings indicated that the site was located south of the pistol range and K Road, and east of Long Creek. It was probably used during the 1940s and early 1950s as a demolition area for ammunition items and for demilitarizing white phosphorous rounds.

Drawings reviewed for the Possible Demolition Site included the 1945 Day and Zimmermann, Inc. drawing titled "Contm'd Areas Near East Boundary-South of Lower Augusta Rd. & East of YD. 'E'", which identifies three contaminated areas at IAAAP including the Possible Demolition Site MRS. Based on the location obtained from the drawing, no ground scarring was observed in the aerial photographs reviewed for this area; however, the 1957 aerial photo indicated ground scarring just to the east of the Possible Demolition Site location identified in the 1945 drawing.

There is no documentation to indicate that demolition activities occurred at this site or which types of ammunition items were treated. The size of the site was also unknown. In 1991 PA/SI sampling was completed and no significant contamination was found.

CLEANUP STRATEGY

In October 2007 the SI was completed. Per the agreements made in the December 2006 dispute resolution, the US Army has agreed to complete RIs at all MMRP sites at IAAAP. The RI began in April 2008. The site was reduced to 484 acres based on preliminary RI work. The MRS Prioritization Protocol score for this site was reviewed in FY09.
