Bay Area Air Quality Management District (BAAQM) Review of Current Air Monitoring Capabilities Near Refineries

Eric M. Fujita and David E. Campbell Division of Atmospheric Sciences Desert Research Institute, Nevada System of Higher Education Objectives • Identify the primary risk drivers • Review and evaluate current air monitoring capabilities. • Develop a matrix of instrumentation, methodologies and/or other exposure assessment tools to: – enhance monitoring capabilities – provide information about emissions • Prepare a short report describing the process used and how the matrix was developed. Identifying primary risk drivers Risk factors Potential emissions from upset conditions Emissions from normal operations Chronic effects Acute effects Fu gi ti ve em is si n s Target compounds, RELs, and monitoring methods Open Path 500m OpenPath 100m Area Target Compound Acute (µg/m3) Chronic (µg/m3) Photo- metric Auto-GC XRF tape sampler 6 UV-DOAS OP-FTIR 7 DIAL Canister Chemically active adsorbent FRM filter sampler Passive lpm filter sampler Benzene 1300 60 0.03 3 50 3 0.06 0.3 1,3 Butadiene 20 0.02 1 10 0.04 0.03 Formaldehyde 55 9 10 10 8 µg/m3 h 0.15 Acetaldehyde 470 140 20 6 µg/m3 h 0.05 Perchloro- ethylene 20000 35 40 0.02 Napthalene 9 0.05 2 ?
