Construction Permitting (ATI / PTO)



The Air Quality Division reviews designs and performance objectives for all sources of air contaminants to determine their likely compliance with state and federal and local requirements. Facilities meeting requirements are issued construction permits known as an Authorization to Install (ATI). New facilities must be designed to meet emissions standards and not result in a violation of ambient air quality standards. In the case of large new facilities, a more complicated analysis of proposed emissions is required. This process is called a "PSD Review."

The construction permit application forms can be found on the "RESOURCES" page. These application forms are required by the Air Quality Division prior to constructing or modifying equipment or control equipment. These application forms are similar to the DNR’s application forms. See the Instructions form for which forms will be required. Although not all forms will be required upon initial submittal, the Department reserves the right to require the facility to submit all upon request.

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 after July 1 each year (start of the county fiscal year).
