Administrative changes for air permits

#FFFFFF

Important update: As of October 2024, permit applicants are encouraged to use the division’s new electronic submission process to submit Modeling Requirements Determination Form APCD-114.

As a courtesy, the division will continue to accept the Modeling Requirements Determination Form APCD-114 (August 2024) as a PDF through Dec. 1, 2024. After that date, permittees must submit Form APCD-114 using the new electronic submission process.
