Simple Cycle Combustion Turbine Air Permitting Project

Burns & McDonnell performed air dispersion modeling and a Best Available Control Technology (BACT) analysis in support of a Prevention of Significant Deterioration (PSD) permit application for the 160-MW Ameren Pinkneyville Simple Cycle Project. These services were provided in conjunction with engineer-procure-construct (EPC) services by Burns & McDonnell.

Because the project had a potential to emit in excess of the PSD significant levels, a BACT review was required. BACT emission limits were compared to applicable NSPS (40 CFR Part 60) or National Emission Standards for Hazardous Air Pollutants (NESHAP) (40 CFR Part 61) to ensure the most stringent requirement was met. All these analyses showed that the project would comply with state and federal Environmental Protection Agency air quality regulations.

The ambient air quality analysis was performed using the latest version of the Industrial Source Complex short-term model (ISCST3) on various combinations of simple cycle combustion turbines including four S&S Energy Products LM 6000PC. The results were compared to the National Ambient Air Quality Standards and Significance levels. An analysis of the facility's potential to impact ambient ozone concentration was also performed.
