Your attention is directed toward the permit conditions within the permit(s) especially Condition 1 (Emission Limits), Condition 2 (Compliance Demonstration), and Condition 5 (Operating Requirements with Associated Recordkeeping and Monitoring).  Based upon the submitted application(s) the Department has made the following determinations:
 This facility is not subject to NSPS because there are no applicable subparts. 
 This facility is subject to NESHAP subpart XXXXXX, National Emission Standards for Hazardous Air Pollutants: Area Source Standards for Nine Metal Fabrication and Finishing Source Categories. This facility is of the source category for Subpart MMMM  -  Surface Coating Miscellaneous Metal Parts and Products (40 CFR §63.3880- 40 CFR §63.3981) of the National Emission Standards for Hazardous Air Pollutants (NESHAP).  Only "major sources", as defined in 40 CFR § 63.2, are subject to this subpart. In this project, the facility was able to establish enforceable limits to become an area source of HAP per EPA's guidance document ("Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act", 1/25/18). Hence, the facility is an area source and not subject Subpart MMMM. 
 This project makes this facility a minor stationary source for the Title V Operating Permit program. If you want to rescind your Title V permit please contact Weston Li at (515) 725-9580 or Chris Kjellmark at (515) 725-9537.
 This facility is a minor source for Prevention of Significant Deterioration (PSD).
 Stack testing is not required for this project.  The Department maintains the right to require testing of any source of emissions in the future if needed [567 IAC 25.1(7)].

Per 561 IAC 7.4(1), the owner or operator shall file any written notice of appeal within thirty (30) days of receipt of the issued permit(s).  The written notice of appeal shall be filed with the Director of the Department with a copy to the Legal Services Bureau Chief at the following addresses:

Director
Iowa Department of Natural Resources
502 East 9[th] Street
Des Moines, IA  50319
Bureau Chief
Legal Services Bureau
Iowa Department of Natural Resources
502 East 9[th] Street
Des Moines, IA  50319

In addition to the permits you will find one (1) copy of each of the following attached to this letter: Start-up Notice, Start of Construction Notice, Response to Comments, and a list of definitions and acronyms.  When requesting a modification to any of the permits, use the permit number and your plant number for identification.  For future reference a status report of all construction permit applications submitted to the Department is available at www.iowadnr.gov/airpermitsearch.  If you have any general air quality construction permitting questions please call 1-877-AIR-IOWA.  If you have any questions about these permits, feel free to contact me by phone at (515) 725-9563 or by email at gary.smith@dnr.iowa.gov .
