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.
