Project Level Training for Quantitative PM Hot-Spot Analyses

EPA has developed a three-day training course on completing quantitative PM hot-spot analyses according to EPA's "Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas" (the PM Hot-spot Guidance). Additional information, including a more detailed course description, is found below. There is no registration fee for this course.

Course Information

This page will be updated with the course materials as additional training sessions are scheduled.

The course is based on the November 2015 version of the PM Hot-spot Guidance and is based on MOVES2014a and AERMOD 16216r. The course materials are designed to be a resource for practitioners to reference on their own.

Please note: The course materials include a module on CAL3QHCR and associated CAL3QHCR exercises, but this model can no longer be used for PM hot-spot analyses. This model has been replaced with AERMOD as the Appendix A preferred model for refined modeling for mobile source applications.  For more information, refer to EPA’s refer to EPA’s Guideline on Air Quality Models - Appendix W (PDF) (54 pp, 848 K, About PDF). Also note that this training does not include the California emissions model, EMFAC.

Course Description

This three-day course provides detailed, hands-on instruction on how to complete a quantitative PM hot-spot analysis in accordance with EPA's guidance. This course is geared towards state and local agency staff who will be completing these analyses, as well as those who may be reviewing, approving, or otherwise assessing hot-spot analyses. Previous modeling experience is not necessary, although familiarity with MOVES and air quality dispersion modeling may be helpful. The course includes class discussion and numerous hands-on exercises, including a hypothetical project that will be carried through the course as an example of a quantitative PM hot-spot analysis.

The course includes the following topics:

  1. An overview of the PM Hot-spot Guidance;
  2. Using MOVES at the project level for PM hot-spot analyses;
  3. Selecting an air quality model, data, and placing air quality modeling receptors;
  4. Using the AERMOD dispersion model for a hot-spot analysis;
  5. Estimating background concentrations; and
  6. Calculating design values.

An agenda for this course is available. As most elements of the course build on each other, participants should be prepared to attend the entire class to obtain the full benefits of any in-person training.
