Briefing Outline

  • DNSC Mission

  • Defense Stockpile of Elemental Mercury

  • EIS Process

  • Public Outreach

Briefing outline

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.

Briefing outline

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

Briefing outline

Security Measures

  • Perimeter fence surrounding depot

  • Armed security, 24 hours per day, 7 days per week

  • Controlled access to warehouses

  • Controlled access to depot

Briefing outline

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

Briefing outline

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

Briefing outline


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

Briefing outline


  • 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

Briefing outline

Consolidated Storage

  • Federal Register Notice to all Federal Agencies

  • March 5, 2001

  • Follow-up letter to specific agencies

    • Potential sites to be evaluated

Briefing outline


  • 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

Briefing outline

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)

  • Briefing outline

    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)

    Briefing outline

    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.
