SUCCESSES/CHALLENGES
Ensuring compliance at high-impact sources continues to consume a large
portion of the Air Quality Compliance Program’s resources. In addition to on-site
inspections the Program reviews compliance certifications, report submittals,
stack test results, sampling results, and continuous monitoring summaries to
assess compliance at regulated facilities.
Due to the large number of sources, low-impact facilities continue to be an area
where only a small percentage of sources are inspected. In this arena the Air
Program continues to focus on Stage II vapor recovery systems at gas stations,
as well as dry cleaners. There are about 1,700 gas stations subject to Stage II
requirements to limit emissions of volatile organic compounds, a ground-level
ozone precursor. The Air Program is also focusing on ensuring compliance with
federal air toxics requirements at dry cleaners.
