Background

A large Midwestern cement manufacturer retained Foth to complete a Major Source (i.e., 40(CFR) Part 70 Title V) Prevention of Significant Deterioration (PSD) air permit renewal. Comprised of more than 200 emission source locations, the permitted source’s manufacturing process was complex, and timely submission was required to ensure the client’s continued compliance with applicable federal and state regulations.

Approach

As defined by the U.S. Environmental Protection Agency, prevention of significant deterioration “applies to new major sources or major modifications at existing sources for pollutants where the area the source is located is in attainment or unclassifiable with the National Ambient Air Quality Standards (NAAQS).” The permit renewal process included reviewing major process equipment, including applicable Maximum Achievable Control Technology (MACT) requirements. We also evaluated existing emission calculations, and interfaced with the state regulatory agency on behalf of the company to complete a complex permit application containing a number of emission source locations and PSD designation.

Results

A collaborative working relationship between the client and Foth expedited the permit preparation process, which assured ongoing compliance by the cement manufacturer and helped our client avoid any negative regulatory recourse. We completed the task by the promised deadline (the project timeline, from start of contract to completion, was less than 45 days), and with a guaranteed fixed price, our solution resulted in client satisfaction.
