Air Dispersion Modeling Analysis Form AERA-03 Air Emissions Risk Analysis (AERA) Doc Type: Air Emissions Risk Assessment – External Documentation Purpose: This form describes the air toxics modeling assumptions and methods used in an AERA. Criteria pollutant modeling forms are found on the Minnesota Pollution Control Agency (MPCA) website - Air Quality Dispersion Modeling (AQDM) . For general AERA modeling guidance, consult MPCA’s AERA guidance at ; for general dispersion modeling information and guidance, consult MPCA’s air quality dispersion modeling guidance (AQDM) website at . Contents: Information requested for all AERAs General Information Detailed Modeling Descriptions AERA Emissions Source Summary Additional information for projects without criteria pollutant modeling Meteorological data summary Terrain and geospatial summary Building summary Non-point sources Instructions : Check appropriate box by clicking on it. Response areas may be expanded as needed. All AERA documents must be submitted electronically. Spreadsheets should not be submitted in pdf format. The AERA will be deemed incomplete if all requested forms and support documents are not included . This form is submitted as part of a: Protocol/workplan Completed AERA Facility Information Facility name: AQ Facility ID No.: General Information Check appropriate box by clicking on it. Response areas may be expanded as needed. Select all of the modeling methods used. RASS "look-up" table dispersion factors AERMOD to generate dispersion factors for the RASS (using 1 g/sec emission rates) AERMOD to generate individual pollutant concentrations for the RASS AERMOD to generate risk estimates by modeling Q/CHI sums instead of emission rates AERMOD to conduct deposition modeling for input into a HHRAP-based analysis (e.g., IRAP) AERMOD to generate unitized dispersion factors for MMREM AERMOD to generate mercury air concentrations for MMREM Other (explain): Indicate why the specified modeling method is selected. AERMOD modeling is not done because RASS lookup tables showed results below risk guidelines AERMOD modeling is done after conservative screening modeling results were submitted AERMOD modeling is done without submitting conservative screening modeling results Other (explain): 651-296-6300 • 800-657-3864 TTY 651-282-5332 or 800-657-3864 Available in alternative formats aq9-03 12/16/14 Page 1 of 6

Indicate what support documents are being submitted. If this form is being submitted as a protocol, include at least one sample of each of the appropriate files listed below. A sample represents the framework of how the model will generally be set up and may not include facility specific source inputs. If this form is being submitted to describe results, submit all of the following files used in the analysis: AERMOD input: sample complete set (*.inp, *.adi, *.ami) (Input file should include buildings and receptor grid(s))
