Ambient Air Monitoring

Ambient Respirable (PM4) Crystalline Silica Fenceline Sampling Programs

Air Control Techniques, P.C. has designed and supervised long-term ambient PM4 crystalline silica sampling programs at numerous frac sand producing facilities in the Midwest. Many of these studies are in-progress. Published papers concerning some of these studies are listed on the recent publications page.

PM2.5 Sampling

Air Control Techniques, P.C. has designed and is supervising PM2.5 ambient air sampling programs to satisfy operating permit requirements and PSD permit requirements.

PM10 Sampling

Air Control Techniques, P.C. has designed, supervised, and operated PM10 sampling networks to satisfy permit requirements and to help operators demonstrate compliance with local regulatory requirements.

Coarse Particulate Matter Sampling

Air Control Techniques, P.C. is developing a coarse particulate matter sampler that can be used in studies to evaluate the spatial distribution of coarse particulate matter downwind of Mineral Industry Sources.
