Operating Permits (PTO & Title V)



Before the expiration date of the Authorization to Install permit, a Permit to Operate must be obtained. Sources are generally authorized to operate under the ATI until the PTO is issued by the department. The Permit to Operate must be renewed annually. Facilities that currently hold a PTO are issued a notice of renewal in August of each year.

For major sources of emissions, the Federal Title V Operating Permit Program applies. Linn County administers the permitting and enforcement process for the Iowa DNR. However, the Iowa DNR issues all Title V Permits in Linn County and therefore all rules, policies, and application materials issued by the Iowa DNR are used.
