Study of Neighborhood Air near Petroleum Sources
CARB is developing a project to better characterize air quality in communities near oil and gas operations. The Study of Neighborhood Air near Petroleum Sources (SNAPS) includes limited-term, intensive air quality monitoring with a particular focus on production facilities. This project can also provide valuable information to support the Community Air Protection Program (CAPP), formed pursuant to AB 617.
Under SNAPS, candidate communities for monitoring are identified based on their proximity to oil and gas wells, and from public suggestions. CARB staff will locate stationary trailers equipped with state-of-the art monitoring technologies in communities for up to four months to determine air quality. The trailers are capable of measuring toxic air contaminants (TACs), volatile organic compounds (VOCs), particulate matter (PM), metals, and criteria pollutants. An analysis of available air pollution measurements, local characteristics, public input, and potential partnerships in each candidate community will help to prioritize trailer deployment. Staff will analyze the air quality measurements obtained through trailer monitoring to characterize exposures to measured pollutants. Where appropriate, the Office of Environmental Health Hazard Assessment (OEHHA) will perform a more in-depth health analysis, potentially including risk assessment. Some air monitoring data will be posted in real-time and CARB will publish a complete analysis of results in separate reports for each site.
We encourage community members to be involved and provide input to the SNAPS project. Opportunities to participate will be provided locally in each selected community, both prior to and following air monitoring.
