How Do I Apply for the General Permit?
To request coverage under the General State Operating Permit or the General Conditional Major Operating Permit, select one of the following options:
Option 1: If your facility has already been issued an operating permit, download, complete, and submit the State Operating and Conditional Major Permit Renewal Application with the General Operating Permit box selected as follows:
- If the potential uncontrolled emissions are below the major source thresholds select General State Operating.
- If the potential uncontrolled emissions are above the major source thresholds select General Conditional Major.
Option 2: If your facility has completed construction and has not been issued an operating permit, download, complete, and submit the Operating Permit Request to request your initial operating permit.
