A separate application is required for each facility location. This application form does not allow any changes to the permitted operations. Any changes in the process including equipment inventory, location, conditions and throughput of the existing PTO requires the owner to go through the Authority to Construct (ATC) process prior to making the change. In addition, if transferring ownership, if the permit(s) are subject to source testing, the frequency is based on the last time the equipment passed a source test, not the date of the permit transfer. Contact the District if you need assistance.
