  1. Ambient Air Surveillance Program at SNL/NM April 17, 2012 Joanna Eckstein Sandia National Laboratories Air Quality Compliance Program 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-AC04-94AL85000.

  2. Environmentally Related Programs Under Sandia’s Environmental Management System (air related programs are in green) • Air Quality Compliance • Ecology • Energy & Water • Environmental Compliance Coordinators • Environmental Life-Cycle Management • Fleet Services • Groundwater Monitoring • Hazardous Waste Permitting and Compliance Program • Long-Term Stewardship • Meteorology • National Environmental Policy Act • Oil Storage • Pollution Prevention • Radiological National Emission Standards for Hazardous Air Pollutants • Storm Wagner • Surface Discharge • Terrestrial Surveillance • Wastewater Discharge • Waste Operations

  3. Air Sampling at SNL/NM • Ambient Air Surveillance (AAS) Ambient Air - Outdoor air, any unconfined portion of the atmosphere, open air • Tritium Bubblers • Industrial Hygiene

  4. AAS Program Objective AAS is a voluntary and proactive approach to demonstrate the minor impact that operations at SNL/NM have to the ambient air • Regulations: 40 CFR 50 – National Ambient Air Quality Standards (NAAQS) 20.2.3 NMAC – NM Ambient Air Quality Standards (NMAAQS) • Establish background concentration levels for pollutants of concern • Evaluate the effects, if any, from SNL/NM operations on the public and the environment

  5. Criteria Pollutant Monitoring Station (CPMS) • Criteria pollutants are the set of common pollutants for which the U.S. EPA must set NAAQS for according to the Clean Air Act • sulfur dioxide (SO2) • carbon monoxide (CO) • nitrogen oxides (NOx) • ozone (O3) • The one CPMS at SNL/NM has been in operation since 1994

  6. Sulfur Dioxide Trending Results (ppm)

  7. Carbon Monoxide Trending Results (ppm)

  8. Nitrogen Dioxide Trending Results (ppm)

  9. Ozone Trending Results (ppm)

  10. Particulate Matter less than 10 microns in diameter (PM10) • PM10 are measured at four monitoring locations at SNL/NM • 1 monitor in Tech Area 1 • 1 monitor in Tech Area 2 • 2 monitors in Tech Area 3 • Have been in operation at SNL/NM since 1994 • Total PM10 is weighed for comparison to the AAQS • Sampling filters are analyzed for metals and radiological constituents (for screening purposes)

  11. PM10 Trending Results (µg/m3)

  12. Particulate Matter less than 2.5 microns in diameter (PM2.5) • PM2.5are measured at two monitoring locations at SNL/NM • 1 monitor in Tech Area 1 • 1 monitor in Tech Area 3 • Have been in operation at SNL/NM since 2004 • PM2.5measured continuously and recorded in hourly concentrations 24 hours-a-day, 365 days-per-year

  13. PM2.5 Trending Results (µg/m3)

  14. Volatile Organic Compounds (VOC) • VOC’s are measured at four monitoring locations at SNL/NM • 2 monitors in Tech Area 1 • 1 monitor in Tech Area 2 • 1 monitor in Tech Area 3 • Have been in operation at SNL/NM since 1994 • The VOC samples are analyzed for 32 VOC species plus total non-methane hydrocarbon (TNMHC)

  15. Analysis of VOC Monitoring Results • VOC results compared to Threshold Limit Value (TLV) TLV of a chemical is a level to which it is believed a worker can be exposed day after day for a working lifetime without adverse health effects (ACGIH determined) • There has never been a result in VOC ambient emissions that has exceeded a TLV at SNL/NM • Detailed VOC analysis can be found in the Annual Site Environmental Report (ASER) each year

  16. In Conclusion • All testing results associated with the Ambient Air Surveillance Program at SNL/NM are documented annually in the ASER • There has never been a sampling result that has exceeded NAAQS, NMAAQS or the TLV for the associated chemicals at SNL/NM
