Relating to the monitoring of emissions from certain facilities that emit air contaminants.

HB 2267 requires operators of specific concrete and aggregate facilities in Texas to monitor air contaminant emissions at their facility boundaries. It applies to facilities producing aggregates (as defined by state water law), crushing concrete, or performing wet/dry batching or central mixing at concrete plants. The bill mandates the Texas Commission on Environmental Quality to establish rules for this boundary monitoring, effective September 1, 2025. This is a new monitoring requirement for these facilities, not a change to emission limits or enforcement.
