The purpose of the hearing was to focus on the Interstate Power and Light Company, also known as Alliant Energy, air quality permit applications for the center, and it was the final opportunity for people to make their voices heard. DNR Air Quality Bureau Senior Engineer Michael Hermsen said the Alliant proposal is for the construction of three new natural gas combustion turbines to be called the Bobcat Energy Center. Before opening the meeting to comments, he said the project has passed air quality inspections. Extensive computer modeling of air dispersion was also performed to evaluate the potential emissions on the surrounding air quality. Zayudis told her the DNR's role is to evaluate the issuance of air quality permits.
