Companion EPA Methods 325A (sampler deployment and collection) and 325B (sampler preparation and laboratory analysis) are the work practice standards for determining airborne Benzene and select Volatile Organic Compounds (VOCs) using passive (diffusive) sampling tubes collected at facility property boundaries (fenceline monitoring) as well as from fugitive and area emission sources.

Air sampling can be more involved and more difficult at times than sampling for water and solids.

One of the most common ways to collect air samples is using passive summa canisters. Learn more about them here.

For the first time ever, the EPA will be adding a compound to the Hazardous Air Pollution (HAP) list.

40 CFR Part 64 Subpart FFFF establishes National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Organic Chemical Manufacturing (MON). This subpart establishes requirements to demonstrate initial and continuous compliance with the emission limits, operating limits, and work practice standards.

A winter chill has floated into Research Triangle, NC and will likely transitioned to a cold shiver as we move through the winter months. Meanwhile, our stack-tester friends are still going strong out in the field knocking out one test after another.
