Conventional Environmental Sites to be Investigated

Final Site Inspection (SI) Report currently under VDEQ review

Historic aerial photographs facilitated supplemental SI sampling

Supplemental SI sampling to be conducted Spring 2009 at 15 sites to determine if either No Further Action or some additional investigation is warranted

3

Conventional Environmental Sites to be Investigated

Dog Beach Landfill and Moat will be addressed via a Remedial Investigation (RI)

Removal or Remedial Action may be needed at 2 – 3 sites to mitigate risk

4 sites being evaluated further for Ecological Risk only

Dog Beach Landfill

Possible landfill cap/cover system

Contours of landfill design

Public access and use in Parks and Recreation Area

Landfill Post-Closure Care and Maintenance

Geophysical Investigation of possible munitions to coincide with Remedial Investigation

Munitions (MEC) Sites to be Investigated

Munitions Remedial Investigation (RI) contract awarded in October 2008 to EA Engineering, Science and Technology

Draft Munitions RI Work Plan generated November 2008

Comments provided by stakeholders in December 2008

Geophysical investigations will be conducted at 13 Munitions Response Areas (MRA) in Spring/Summer 2009. The off-shore Chesapeake Bay Target MRA investigation has been deferred

Site walk of the Mill Creek emergent

wetlands islands is scheduled Spring 2009

Munitions (MEC) – Technical Topics

Issue: The amount of Munitions digital geophysical mapping (DGM) required for reuse

FMFADA technical support (Matrix) goal is 100% DGM of all accessible areas to support cleanup and future use

Ft. Monroe maintains that the RI requirement is to only characterize the Munitions contamination; not all accessible areas. Enhanced RI to be developed to address this concern, and to validate historically collected information & mapping

VDEQ awaiting submittal of Enhanced RI components for evaluation purposes

7

Munitions (MEC) – Technical Topics

Issue: Depth of water to investigate possible Munitions in Chesapeake Bay Near-Shore Area (Northern Section)

VDEQ and FMFADA technical support (Matrix) maintain that current & future use via swimmers & waders needs to be addressed

Ft. Monroe & US Army recognize that current & future use via swimmers & waders need to be addressed, to a proposed depth of 3 feet of water

U. S. Army Schedule for Future WorkU. S. Army Schedule for Future Work

Conventional & MEC Environmental Sites

In June 2008, a discussion of cleanup priorities began. Assumptions being recreational areas are the highest priority in the environmental cleanup sequence

RI/FS work scheduled in 2009 and 2010. Proposed Plan and Record of Decision projected in 2010
