Ongoing Work: What will EPA and Vistra do if there are elevated readings detected by the air monitors?

Return to: Frequently Asked Questions

Under our oversight, Vistra continues to maintain 24/7 air monitoring and sampling. Sampling and monitoring will happen around the site perimeter and in the community. If monitors show elevated readings, work stops. If changes to work processes are needed, Vistra will make the changes to fix the problem under EPA’s direction and oversight.

Vistra can re-direct their contractors (already in the community maintaining air monitoring equipment) in minutes to confirm readings. Technicians are available at any time to service the stations if needed. The contractors can also deploy “roaming” (or mobile/handheld) monitors to check locations of interest based on the wind direction. Note: Contaminant levels can spike due to activity unrelated to site work. (For example, fog or road traffic may spike particulate matter levels.) As such, the reason for data changes must be closely studied and confirmed.
