Mercury Management Environmental Impact Statement EPA Breaking the Mercury Cycle: Conference on Mercury Retirement Boston, MA May 1-3, 2002 Cornel Holder Deputy Administrator Defense National Stockpile Center
Briefing Outline • DNSC Mission • Defense Stockpile of Elemental Mercury • EIS Process • Public Outreach
Defense National Stockpile Center (DNSC) • DNSC, a part of DLA, has been selling commodities on the open market. • The Stockpile of strategic and critical materials was purchased to reduce the United States’ dependence on foreign sources of supply during national emergencies. • DNSC currently stores 60 different commodities at 56 locations.
DoD Mercury Stockpile • No DoD requirement for elemental mercury • DNSC sales suspended in 1994 • 4,436 metric tons of elemental mercury in inventory • Elemental mercury continues to be mined and imported • Long-term solutions needed for elemental mercury management
Security Measures • Perimeter fence surrounding depot • Armed security, 24 hours per day, 7 days per week • Controlled access to warehouses • Controlled access to depot
Safety Measures • Jerome Mercury Vapor Analyzer • Measures in parts per million • Lumex, state-of-the-art, mercury air-monitoring equipment • Measures in parts per billion
Past Mercury Storage • Entire inventory re-packaged in 1975.(699 metric tons) • Seamless 3-liter containers used • Will over-pack if consolidated at another location • 3-liter capacity, steel flasks • Wooden pallets on metal catch trays • Sprinkle system in warehouses
Over-packing Levels of protection 1. Steel flask. 2. Absorbent pad. 3. Plastic liner. 4. Epoxy-coated drum. 5. Drip pan. 6. Epoxy-coated floor. 7. Secure warehouse. • Flasks cleaned and inspected • Six flasks to a 30 gal drum • Flasks transferred to DOT approved, air and liquid-tight drum

Environmental Impact Statement Process Public Scoping Process Notice of Intent Proposed Action Scope of Statement Draft Environmental Impact Statement Final Environmental Impact Statement Record of Decision Public Comments
Alternatives • No Action: continued storage at present locations with air-monitoring • Consolidated storage at one site • Sales that do not unduly disrupt market • Treatment of elemental mercury followed by disposal
Consolidated Storage • Federal Register Notice to all Federal Agencies • March 5, 2001 • Follow-up letter to specific agencies • Potential sites to be evaluated
Sales • Analyze environmental impacts of DNSC sales • Estimated annual domestic consumption 300 metric tons • Resume DNSC sales at a maximum rate of 5,000 flasks per year (173 metric tons) • Approximately 30 years to sell entire inventory • Not to unduly disrupt market
Treatment Followed by Disposal • Processing elemental mercury (evaluate environmental impacts) • – Use DEE-MERC technology (IT Corporation/Nuclear Fuel Services, Inc., Knoxville,TN) • – Create a sulfur compound for land disposal • (PermaFix, Kinston, TN) • – Use selenium to amalgamate mercury for disposal • (McCoy Environmental Technicians, Inc., Columbus ,GA)
Treatment Followed by Disposal • Treating elemental mercury (evaluate environmental impacts) – Use Sulfur Polymer Stabilization and or Solidification (SPSS) process. (Brookhaven National Laboratory, Upton NY) • – Use SPSS at an established mercury treatment facility for disposal. (Bethlehem Apparatus Co., Inc., Hellertown PA)
Process and Store Alternative Eliminated • Mercury can be safely stored in its elemental form. • Elemental mercury is the desired starting point for most industrial uses. • A process and store alternative would result in no significant benefits.
