The Construction Permits Section reviews designs and performance objectives for all sources of air contaminants to determine their likely compliance with state and federal requirements. Facilities meeting requirements are issued construction permits. New facilities must be designed to meet emissions standards and not result in a violation of ambient air quality standards. In the case of complex projects (PSD, SIP, Netting, Major Greenfields, etc.), a more detailed analysis of proposed emissions is required especially those subject to "PSD Review". The acronym stands for prevention of significant deterioration, and recognizes the impact large sources of emissions can have on a region. PSD projects require a pre-application meeting in order to allow the departmental review and permit issuance to meet the goals established by industry and the department. Please review the guidance materials below for the type of project you will be proposing. If you are unsure what applies to you, or simply need help with the construction permitting process, call 1-877-AIR-IOWA (1-877-247-4692). Landfills and NSPS Applicability NEW!

Grain Elevators
Country grain elevators, country grain terminal elevators or grain terminal elevators are classified as Group 1 facilities in 567 IAC 22.10(455B) if the potential to emit of the facility is less than 15 tons of PM10 per year. Owners or operators of Group 1 grain elevators are required to submit a registration form by March 31, 2008 for existing equipment. Click on the link below to check on the status of Group 1 registrations by facility and location. The list is updated weekly on Fridays. List of Group 1 Registrations (PDF File)
The Environmental Protection Commission adopted new grain elevator permitting rules on January 15, 2008. The rules will become effective on March 19, 2008. (See link below for copy) The rules modify requirements for certain types of grain elevators and feed mill equipment collocated at certain types of grain elevators. The rules define each type of grain elevator facility and specify for each type of grain elevator the permitting options, emissions calculation methodology, emissions reporting and record keeping, and best management practices for controlling air pollution. A new particulate matter emissions standard for bin vents located affected grain elevators was also established through amendments to subrule 23.4(7). Applicants must use the grain elevator PTE calculation tool to determine their group classification. A link to the calculation tool and user’s manual is included below. Affected owners or operators of grain elevators are required to submit a registration form or applicable permit application by March 31, 2008 for existing equipment. For Group 1 and 2 facilities, as defined in the rule, links to a registration form or a Group 2 permit application can be found below. Permit applications and instructions that can be used for Group 3 or 4 grain elevators, as defined in the rule, can be found here. Permit applications for unpermitted feed mill equipment must be submitted by March 31, 2008. Permit applications and instructions that can be used for feed mill equipment can be found at here. Links to documents with frequently asked questions about the grain elevator rules in general and for each group are included below. Permitting Exemptions
