Air monitoring for carbon monoxide, carbon dioxide, oxygen, nitrogen dioxide, sulfur dioxide, formaldehyde, hydrogen sulfide, methane, volatile organic compounds (VOCs), diesel particulate matter, and fine particles was conducted April 25,
2019 through April 26, 2019.
The air monitoring captured ambient levels prior to the boilers being started up, during the boilers' startup and continued to monitor the ambient air inside the elementary school during normal operation of the boilers as well as the stack analysis performed by the boiler inspector.
