12137.0 Range Complex No. 1121412151216121712181219122012211222122312241225122612271228122912301231123212331234123512361237123812391240124112421243124412457.1 History and Land UseThe Range Complex No. 1 AOC consists of three areas: INPR Site No. 1, the Demolition Area,and the Turret Gunnery Training Range. Figure 3-1 shows the general location of the Range No.1 Complex AOC. Figure 7-1 shows a general overview of the AOC.The INPR Site No. 1 is a bomb target that was in use between 1946 and 1960. The ASRSupplement indicated that the target was configured with concentric circles of 100, 200, and 300ft. However, analysis of historical aerial photos (1965) shows faint concentric circles at 75, 500,and 1000 ft (Figures 7-2 and 7-3). A portion of the safety zone for INPR Site No. 1 lies withinthe non-FUDS property currently used by the Navy Bombing Range. Soil samples werecollected from INPR Site No.1 during the PA/SI.The Demolition Area was used for the demolition of munitions between 1952 and 1960 and maybe the area used by the Umatilla Ordnance Depot for demolition of unserviceable munitions.The area consists of two rows, approximately 200 ft apart (Figures 7-4, 7-5 and 7-6). Each rowhas approximately 20 pits (craters) spaced approximately 50 ft apart. MD was reported asembedded in the crater walls and scattered in a wide radius from the craters (USACE, 1997), andMD was found during the 2007 field activities.The Turret Gunnery Training Range was used to train B-36 Bomber gunners to fire at targetdrones that flew across their front. The turret gun firing points were located on current NavyBombing Range Property and are not FUDS property. Only the downrange portion of the rangeis within the Boardman AFR FUDS. A portion of the safety zone is outside of the FUDSboundary on the active Navy bombing range. The range name is consistent with the ASRSupplement.Much of the northern and eastern portions of Range Complex No.1 are currently being used forirrigated crops (Figure 7-1). The southern portion of the range is used for the Boeing AntennaeTest Range, and wildlife conservation area managed by The Nature Conservancy. Nogroundwater wells are located within the boundary of this AOC. Future land use is expected toremain the same as current land use.7.2 Previous InvestigationsThe ASR visited the Range Complex No. 1 area. The area of INPR Site No. 1 was reported to belittered with bomb bodies in sizes ranging from the 3-lb Mk 23 up to the 2,000 lb BDU-10. Inaddition, the ASR reported finding pieces of heavy metal fragments from high explosiveordnance (USACE, 1997).Boardman AFR Final SI Report.doc 7-1 Contract No. W912DY-04-D-0010 Delivery Order No. 003September 2007
