Recommendations for identification for those remaining AOC are providedbelow: Demolition Area No. 2 Recommended to be identified as an MRS. The area hasbeen used as a munitions demolition area as evidenced by several rows of detonationcraters and a high density of MD. MEC was located and destroyed in June 2006.The MEC risk is considered to be moderate. Access to this area is restricted by theproperty leaseholder The Nature Conservancy.Impact Area Recommended to be identified as an MRS. The area may have beenused for unregulated practice bombing. The Nature Conservancy workers have statedthat MD from practice bombs has been found in the area. The SI field team did notidentify any craters or MD. If Demolition Area No. 2 and the Impact Area are identified as MRSs, it isrecommended that additional investigations for MEC be completed. Additionalinvestigations for MC are not recommended, as concentrations of MC in samplescollected from these two AOCs did not exceed site background or screening values.It is recommended that areas where MEC has been reported but are not included in the fourMRSs presented above or the two additional AOCs recommended for identification as an MRS,be further investigated to determine whether additional MEC is present in the vicinity.11.7 MRSPP ScoringDraft MRSPP scoring was completed for the four identified MRSs. The priority scoring rangesfrom 1 to 8 (highest to lowest). The draft priority scores for the four MRSs are:MRSMRSPP Priority ScoreTarget No. 1 6Target No. 2 4Carty Reservoir Bomb Target 3Range Complex No. 1 4With the exception of Target No. 1, none of the MRSs presented sufficient risk to human healthor the environment from MC to merit valuation under the HHE MRSPP module. Thus, in all butTarget No. 1, the MRSs received the HHE rating of No Known or Suspected MC Hazard.Target No. 1 was assigned value under the HHE module due to the presence of ironconcentrations above the background values in a groundwater sample collected onsite. Overall,the MRSPP priority scores for the Boardman AFR MRSs reflect the risk of explosive hazards,Boardman AFR Final SI Report.doc 11-3 Contract No. W912DY-04-D-0010 Delivery Order No. 003September 2007
