  • 7. AOI 14 SITE BACKGROUND . 7 ● Over 400 soil samples collected  from AOI 14 during various  investigations conducted from 1992  to 2014 ● N217 and N217A Areas:  ● 5.5 acres, native and fill  material ● Areas do not pose  unacceptable risk to human  and ecological receptors ● Former Soil Fill Area:   ● 8 acres, fill material placed on  existing surface of stormwater retention pond  ● Area poses potential current  and future risk to human and  ecological receptors
  • 8. • Fill material placed at the Former Soil Fill Area (FSFA) is – contaminated with PCBs, DDT, and Lead – potential source of contamination to surrounding stormwater pond (Navy Installation Restoration (IR) Site 25) REASON FOR REMOVAL ACTION AT AOI 14 8
  • 9. • NASA, with EPA and Water Board concurrence, is conducting a non-time critical removal action (NTCRA) to prevent erosion of contaminated soil from AOI 14 to adjacent Navy IR Site 25 REASON FOR REMOVAL ACTION AT AOI 14 9 – Currently, silt fence in place to prevent soil erosion • NTCRA intended to: – Evaluate and address all potential human and ecological risks – Serve as the final action at AOI 14
  • 10. • Engineering Evaluation/Cost Analysis (Final September 2015) – Summarizes contaminants, potential risks, and exposure pathways – Evaluates cleanup options for effectiveness, implementability, and cost – 30-day Public Comment Period completed October 5, 2015 • Action Memorandum (Ongoing) – Documents the cleanup decision process and identifies the selected cleanup option • Removal Action (Targeted for September 2016 to March 2017) – Removal Action Work Plan—design document – Implements the cleanup action AOI 14 TIMELINE 10
  • 11. Objectives: • Prevent erosion of contaminated soil to protect wetland receptors • Prevent terrestrial ecological receptor exposure to contaminated surface and subsurface soil • Prevent industrial worker exposure to contaminated surface and subsurface soil Cleanup Goals: • Consistent with Site 25 cleanup goals for DDT, PCBs, Lead REMOVAL ACTION OBJECTIVES AND CLEANUP GOALS 11
  • 12. • AOI 14 Engineering Evaluation/Cost Analysis evaluated and compared three cleanup alternatives: – Alternative 1: No Action – Alternative 2: Soil Cover and institutional controls – Alternative 3: Excavation and Off-site Disposal EE/CA ALTERNATIVES EVALUATION 12
  • 13. Alternative 3: Excavation and Off-site Disposal • Excavation of all fill material in the northern portion of the FSFA where contaminant concentrations exceed cleanup goals • Transportation of contaminated soil off site to an appropriate disposal facility • Grading of disturbed areas for stormwater drainage, revegetation, and habitat mitigation NASA’S SELECTED ALTERNATIVE FOR AOI 14 13

  • 15. Implementation of Alternative 3 will: • Allow complete onsite habitat mitigation and habitat improvement RESULTS OF AOI 14 REMOVAL ACTION 15 • Allow for unrestricted site use • Require no long- term O&M • Serve as the final action for AOI 14
  • 16. • Finalize the Action Memorandum (April 2016) • Removal Action Work Plan (August 2016) • Implementation (September 2016 to March 2017) • Removal Action Completion Report (October 2017) NEXT STEPS 16
