Ambient Monitoring of Particulates, Including Crystalline Silica, Near Aggregate Production Operation (APO) Facilities, Interim Report

The TCEQ is conducting an air monitoring project using published methods to measure crystalline silica concentrations near APOs. The goal is to determine what contribution, if any, the APO facilities have to ambient air concentrations of PM4 crystalline silica and total PM2.5 relative to background levels in the Central Texas area.
