The opinions, findings, and conclusions expressed are those ofthe authors and not necessarily those ofthe Environmental Protection Agency. L:\MMR\PLAN\FINAL\DFSPDEMOS.DOC November25,1997 Final FSP Areas 12 and 13 A.11 Area 12 and 13 Field Sampling Plan A.11.1 Background and Focal Area(s) Areas 12 and 13 are both Demolition Areas, which are restricted access areas indicated on Figures A.l1-1 andA.l1-2. Area 12 is Demo Area 1, located north ofForestdale Road as indicated in Figure A.l 1-3. Approximately two acres within Demo Area 1, which lie in the topographic low in the center ofthe area, have been used for demolition activities inthe past. The low area is relatively flat and clear ofvegetation. There are visual signs ofdemolition activity consisting ofsmall craters in this area. The flat, cratered, 1-acre area is a focal area. The remainder ofDemo Area 1 is densely vegetated and appears undisturbed. Area 13 is Demo Area2, located north ofGibbs Road as indicated in Figure A.l 1-4. Approximately 15 acres within Demo Area2 appearto have been used for demolition activities at some point in the past based on clearing ofvegetation. The 15-acre area consists ofthe valley in the center ofthe area and the hill leading from the valley to the bunkeronthe eastern boundary ofDemo Area 2. This hill was graded during engineering work performed on the bunker within the last 6 months, and it is unvegetated. There is evidence of recent demolition activity on this hill consisting of four demolition craters. These craters are a focal area ofless than 0.1 acre. The northern portion ofthe valley is clear ofmost vegetation and has visual signs ofdemolition activity consisting ofdemolition craters and debris. This portion ofthe valley is a focal area ofapproximately 3 acres. To the west ofthis areathe valley is revegetated withtrees but has minimal undergrowth and shows signs ofpast use in the form ofscattered debris and few craters. This portion ofthe valley is a focal area of approximately 2 acres. The remainder of Demo Area 2 is covered with tall trees and dense undergrowth and appears undisturbed. & A.11.2 Sampling Analysis Methods Areas 12 and 13 sampling will include surface soil at each focal area. Areas 12 and 13 sampling will also include subsurface soil and groundwaterbased on the potential for contaminants to migrate into deeper soils or groundwater. MMR Sample collection will be consistent with SOPs, the Ogden Health and Safety Guidelines, L:\MMR\PLAN\FINAL\DFSPDEM0S.DOC 1 November25,1997 • I Final FSP Areas 12 and 13 m E B B B Legend Ar* MMRBoundary -V ImpactAreaBoundary A/ Roads A/ FigureLocation • Wells F G U R E I MMR-Area12VicinityMap A.ll-1 L:\MMR\PLAN\FINA1ADFSPDEMOSDOC November25,1997 Final FSP Areas 12 and 13 Legend /V* MMRBoundary ImpactAreaBoundary A/ Roadi /V FigureLocation ® Wells F I G U R E MMR-Area13VicinityMap A.ll-2 ftawrtwol/HMf^lctwtfuw L:\MMR\PLAN\FINAL\DFSPDEMOS.DOC November25,1997
