11/2/20061 Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL Mark Brynildson Susie Orth SNL/CA Environmental Management Department Hazardous Materials Management Program Chemical Inventory Reduction Processes and Metrics at Sandia National Laboratories/CA (SNL/CA) Sandia Report SAND P Unlimited Release Printed October 2006

11/2/20062 SNL/CA Hazardous Material Reduction Drivers 2006 SNL/CA EMS Goal - 5% reduction by container 2006 reduce NFPA Health 3 and 4 materials in the 5 EPHA target areas with the objective of eliminating at least 2 out of the proposed 5 areas. New DOE Requirements –DOE O 151.1C Emergency Management - Hazards Survey focus on NFPA Health 3 & 4 Materials (11/2005) –DOE requirement on the Management of Unneeded Materials and Chemicals (UMC) (12/2005) Existing Sandia Requirements –ES&H Manual Section 4P - Housekeeping Chapter 5 - Fire Protection Section 6D/6E - Haz Comm/Lab Standard - Chemical Hygiene Plan Section 6U - Chemical Barcoding and Inventory –Fire Protection International Fire Code Implementation

11/2/20063 Inventory Reduction Campaign Emphasis Hazardous Materials (> 10 years old) –23% of the SNL/CA site inventory is > 10 years old –24% of the NFPA Health 3 & 4 inventory is > 10 years old Hazardous Materials (> 5 years old) –45% of the SNL/CA site inventory is > 5 years old –47% of the NFPA Health 3 & 4 inventory is > 5 years old

11/2/20064 Chemical Information System (CIS) Integrated Chemical Inventory and Material Safety Data Sheet (MSDS) Container Tracking System – Current Inventory and Historical Data Storage ~120,000 Tracked Chemical Containers at SNL/NM ~35,000 Tracked Chemical Containers at SNL/CA ~ 25,000 Unique Chemicals/Chemical Products 1500 Chemical Storage Locations (building/room) Dynamic Inventory - Daily Inputs (new entries and disposals) MSDS library of over 85,000 via the SNL Internet Available for Routine or Emergencies On-site and Off-site 24 x 7 Dynamic Library - Daily Inputs (new entries and updates) Basis for federal/state reporting (i.e. Emergency Planning Community Right-To-Know Act)

11/2/20065 Key CIS Business Rules/Functions Conservative Inventory Tracking Rule –All Chemical Containers are Considered Full While in the Inventory Inventory Data is Linked an MSDS –CAS used in MSDSs forIingredients –CAS Unique Identifier for Chemical Structure –Identifies Basic Physical State but not Form Off-line CIS Data Available Quarterly to EOC –Used when CIS is Unavailable (i.e., network/power outage)

11/2/20066 Quality Assurance Annual Chemical Inventory Reconciliation –Reconcile differences between physical inventory and database information –Wall-to-wall walk down is conducted (May – August) –Process ensures that CIS database is in line with physical inventory –Results forwarded to lab owners and ES&H professionals for review

11/2/ Inventory Reduction Data Challenges Baseline Recalculation –Organization Ownership Changes –New Locations/Organizations Inventory is “Lost” and “Found” each year during the Summer Reconciliation Data Presentation Container Count vs. Received Container Contents Weight Very Small or Very Large Containers Allow for Gaming Reduction Results

11/2/ Academic/Organizational Freedom –Ownership/Responsibility Product Chemical Safety –Peroxidizable, autopolymerizable –i.e., Picric Acid –Inventory is “Lost” and “Found” Each Year During the Summer Reconciliation Product Quality –Manufacturer Expiration Dates –General Shelf Life Product Disposal Costs –Line labor –Waste Management Chargeback Inventory Reduction Line Challenges

11/2/ Hazardous Material Safety –Chemical Exposure to Personnel Reduced –General Container Integrity Improved Risk to Environment –Spill Potential Reduced –Fugitive Emissions Reduced Hazardous Material Storage –Storage Space Volume Better Utilitized –Housekeeping Improved Orphaned Hazardous Material –Legacy Cleanup Cost Reduced –Stealth Inventory Management Cost Reduced Inventory Reduction - Conclusions

11/2/ Unresolved Challenges Procurement Controls Inventory Accuracy Requirements & Expectations Inventory Reduction Frequency Inventory Ownership & Orphaned Inventory Inventory Age Profile Metrics Inventory Shelf Life Guidelines Graded Risk-Based Approach Material Safety Data Set Location Based Material Permit Limits Excess Material Redeployment - Chemical Exchange
