  2. FGA Installation Restoration and Compliance Cleanup Programs Reports/Workplans • Following Reports now on RAB website http://www.smdcen.us/rabfga/pages/documents.asp: • Draft Proposed Plan for the Closeout of 9 IRP Sites • Draft 2007 Groundwater Monitoring Report • Final 2006 Remedial Investigation Report • Final 2005 Remedial Investigation Report • Final Miscarriage Investigation follow-up report (on health investigations page) • Following Reports to be on the RAB website soon: • 2006 SM-1A Surveillance Monitoring Report (promised to be submitted by end of March by US Army Corps of Engineers • Jarvis Creek Geophysical Survey Report • Interim South Tank Farm Biotreatment Letter Report

  3. FGA Installation Restoration Program 2007 Fieldwork Completed • Approximately 12,000 CY of petroleum contaminated soil excavated and bioremediated at the South Tank Farm • Treatment Confirmation samples taken in October show some soil still significantly above cleanup levels • Treatment Area will be tilled in Spring to promote aeration and confirmation samples retaken. • Work included receiving approximately 800 CY of petroleum contaminated soil from the North Delta Tank Farm cleanup • Completed June/Sept groundwater monitoring. Results indicate some deep aquifer contamination (ethylene dibromide – leaded gasoline additive) at the South Tank Farm. Other results consistent with previous sampling.

  4. FGA Installation Restoration Program 2007 Fieldwork Completed (continued) • Completed field activities at: • proposed future old post fire station site (elevated DRO found in soils from former Bldg 144 UST) • Bldg 614 Gas Station (tanks confirmed removed, no contamination discovered) • Tar & Asphalt Disposal Area (minor solvent contaminants in samples pulled from under the disposal area) • Jarvis Creek Munitions Burial Area (geophysical inconclusive) • Old Post MOGAS Fuel Line (several locations of elevated DRO in soils identified) • Former Airfield Underground Tank Farm BRAC Site 29 (confirmed tanks removed and no contamination found) • Building 350 – records search/field visit confirmed dry well/septic system removed. No record of or signs of spills from AST) • Bldg 110 Airfield Underground Tank Farm – confirmed elevated DRO remains in subsurface soil • Cold Regions Test Center Modular Building (BRAC 75) – no evidence of contamination found

  5. FGA Installation Restoration Program 2008 Investigation/Remediation Plans • At the South Tank Farm, install two downgradient monitoring wells to determine the extent of ethylene dibromide contamination. Perform additional investigation work to help determine the extent of deep contamination at the South Tank Farm. Complete the bioremediation project. • Sample groundwater monitoring wells across Fort Greely (Spring/Fall) • Design remediation system for subsurface petroleum contamination at the BRAC 94 Old Post UST Farm/MOGAS Fuel line • Install two additional groundwater monitoring wells in Old Post Area – one to determine if TCE contaminants are sinking deeper and one to try to determine source of benzene in MW-5 • Release Proposed Plan for Public Comment • Perform investigations at Bldg 675 Former Laundry to address ADEC concerns with former tank vault.

  6. Installation Restoration Program Proposed Plan • Proposes closeout activities for 9 additional sites (73 of 132 sites closed in 2005 Decision Document) • Sites include: • BRAC Site 31 (Former Landfill #1) • BRAC Site 32 (Former Landfill #2) • BRAC Site 48 (Waste Accumulation Area at Building 626) • BRAC Site 88 (Former Landfills #4 and #5) • BRAC Site 89 (Refuse Burn Pit) • BRAC Sites 90, 132, and Station 21+25 (SM-1A Nuclear Reactor Wastewater Pipeline, Removal Action Laydown Yard and Dilution Well) • BRAC Site 103 (Former Laundry Facility at Former Building 157) • Actions at most of the sites are Dig Restrictions, Land Use Controls, and Five Year Reviews • Refuse Burn Pit has a proposed excavation with off-site disposal of highest lead contaminated soil. Remaining lead contamination at the refuse burn pit would be capped with asphalt • Proposed Plan on the website for RAB member review and will be released for public comment in the next couple of months

  7. PROPOSED PLAN SITES

  8. Military Munitions Response Program (MMRP) • The Army Environmental Center (Aberdeen, MD) and the US Army Corps of Engineers (Sacramento, CA) began an MMRP Site Investigation (SI) at Fort Greely in 2006. • SI Report posted on RAB website • Further action recommended on Site 112 Former Scrap Yard • Boundary Line issued resolved, addendum to add Jarvis Creek Munitions Burial Area as a “further action recommended” site being developed. • Next phase completion date will be dependent on prioritization of nation-wide Army MMRP sites

  9. SM-1A Nuclear Reactor Characterization • US Army Corps of Engineers has not secured funds to complete the All-Hazards Assessment (characterization study of any remaining radioactive contamination from the operation of the SM-1A nuclear reactor). Known contamination consists of the following access restricted areas: • - entombed contaminated reactor structure • - small portion of wastewater pipeline within reactor compound • Historical Records Review site visit completed June 2007. Draft Historical Records Report completed and internally reviewed. USACE not planning to seek external reviews until funding secured to complete All-Hazards Assessment. • Effort is the initial activity for the complete decommissioning of the SM-1A reactor

  10. Health Concerns Investigation • Fort Greely, the US Army Center for Health Promotion and Preventive Medicine (or CHPPM), and the Bassett Army Community Hospital (Fort Wainwright) investigated concerns during winter of 2005-06 over the perceived high rate of miscarriages (and the possibility of environmental causes) • Briefings at 12/01/05 & 3/9/06 Community Meetings on Fort Greely included: • Types and causes of miscarriages • Environmental exposure and environmental risks • Results of the investigations (miscarriage rate is slightly higher than statistical norms for the United States but no environmental factors identified) • Recommendations (Continue to watch miscarriage rate for 2 yrs to determine if miscarriage increase is just variation in a small population) • Website has presentations, posters, and reports www.smdcen.us/health/ • Alaska Dept of Public Health reviewed & validated the investigation/findings • Bassett Army Community Hospital completed two periodic reviews that showed the rates declined as expected and have ended the periodic reviews

  11. FY 2008
