Challenge

The client, a leading supplier of high-quality building-materials, operates one of the largest cement plants west of the Mississippi River. The site is located in one of 35 Air Districts in California. The state required transparent accounting of facilities that release toxic contaminants into the atmosphere.

GES provided air compliance support by first identifying a methodology to demonstrate compliance with a longstanding, prohibitory rule.
