Construction Permitting (ATI / PTO)



General Information

The Air Quality Branch reviews the technical design and performance objectives of all sources of air contaminants to determine their likely compliance with federal, state, and local requirements. Facilities meeting these requirements are issued construction permits known an Authorization to Install (ATI). New facilities must be designed to meet emission standards and not result in a violation of the National Ambient Air Quality Standards (NAAQS).

In the case of large new facilities, a "Prevention of Significant Deterioration (PSD) Review" is required. The Iowa Department of Natural Resources (DNR) issues all PSD permits in Linn County; therefore, all rules, policies, and application materials issued by the DNR are used. Facilities become subject to PSD Review if they emit more than 250 tons per year of any single criteria pollutant or over 100 tons per year if they are one of 28 specific source categories subject to more scrutiny. Every PSD Review is tailored to the facility and process and are subject to the DNR's Air Quality Fee Schedule. Please contact the Linn County Air Permitting Engineer if you have any questions about PSD applicability to your facility.

Construction Permit Application Process

The construction permit application forms can be found on the Resources page. These application forms are required by the Air Quality Branch prior to constructing or modifying the source equipment or control equipment. Instructions are provided in the link above for which forms will be required. Although not all forms may be required upon initial application submittal, the Air Quality Branch reserves the right to require additional forms.

Facilities are required to obtain a Permit to Operate (PTO) before the expiration date of the ATI permit. Sources are generally allowed to operate under the ATI until the PTO is issued. The PTO must be renewed annually. Facilities that currently hold a PTO are issued a notice of renewal after July each year (start of the Linn County fiscal year). The current permit application fees, effective July 1, 2016, are $385 per ATI and $40 per PTO. On July 1, 2018, the PTO fee will increase to $45.
