Dispersion Modeling Guidelines and Other AQB Modeling Publications

An air dispersion modeling analysis must be submitted with each air quality permit application. New Mexico Air Quality Bureau has developed guidelines to aid the dispersion modeler in developing an acceptable analysis and to facilitate the Bureau staff in expediting the review process.

Guidelines, associated documents, and highlights of changes are available for download in MS Word (DOC) or Adobe Acrobat (PDF) format, below.

Document Description

2017 Modeling Guidelines

(For historic reference:

NM Air Dispersion Modeling Guidelines (1 September 2016)

NM Modeling Guidelines Appendix A

Revised 2017 Guidelines were updated to incorporate changes in EPA’s Appendix W. 

2016 Guidelines notes: NMED AQB does require 1-hour NO2 and/or SO2 modeling demonstration for minor source New Source Review Permit Applications. The Bureau also requires 1-hour NO2/SO2 modeling for PSD major sources.

Updated background concentrations from 2013-2015 are included.  (Hobbs PM2.5 background was updated Aug. 8)

Notes that AERMOD output is expressed at standard temperature and pressure, and few results now need elevation correction before comparing to air quality standards.  

PSD Pre-application Guidance

Pre-construction monitoring may be required before a PSD application is submitted.
Air Dispersion Modeling Waiver Request Form Form for requesting a modeling waiver. (Updated June, 2018)
