Guidance on the Use of the Mesoscale Model Interface Program (MMIF) for AERMOD Applications.

PB2018101097

Publication Date	2018
Page Count	21
Abstract	The guidance discussed in this document are recommendations for running the Mesoscale Model Interface (MMIF) program to generate inputs for AERMET and AERMOD. The guidance discussed in this document is an update to the July 2015 MMIF guidance (EPA-454/B-15-001). In this guidance document, when references are made to running MMIF for AERMOD, it should be inferred that this refers to AERMET as well. For regulatory applications, MMIF should be run to generate AERMET inputs as stated in section 8.4.2(a) and 8.4.5.1(b) of the final revisions to EPA’s Guideline on Air Quality Models (U.S. EPA, 2016). Regulatory applications that do not follow these sections of Appendix W will need to consult with the appropriate reviewing authority and guidelines outlined in section 3.2 of Appendix W. Given that Appendix W and specific EPA modeling guidance are often cited in relation to other non-regulatory modeling applications, such as air quality analysis and disclosure purposes under NEPA, the approach presented in this guidance document for regulatory applications also has relevance to these non-regulatory applications. While MMIF can process data for other air quality models (e.g., CALPUFF and SCICHEM), the emphasis in this guidance is for AERMOD applications conducted for regulatory purposes. The guidance document will summarize some of the inputs needed for AERMET and AERMOD MMIF processing, but will refer to the MMIF User’s Guide (Ramboll Environ, 2016) for more details. MMIF users are strongly encouraged to read this user’s guide to obtain specific details on running MMIF.
