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, what participants will need to do to prepare, and how to register, is found below. There is no registration fee for this course.

Course Information

This page will be updated with the course materials in the near future and before the next offering of this course on June 26-28, 2018, and as additional training sessions are scheduled.

The course is based on the latest version of the PM Hot-spot Guidance and includes updates based on the latest versions of MOVES, AERMOD and CAL3QHCR, as well as other improvements. 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 EPA will not present this information at in-person trainings. 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. Using the CAL3QHCR dispersion model for a hot-spot analysis (note: this module will not be presented at in-person trainings)
  6. Estimating background concentrations; and
  7. 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.

Registration and Course Requirements

To participate in the June 26-28, 2018 training session in Ann Arbor, MI:

  1. Email Laura Berry at Due to the fact that this is a hands-on, technical course, class space will be limited to ensure an adequate participant-instructor ratio. 
  2. Download and read EPA's PM Hot-spot Guidance before attending the course. Being familiar with the guidance will allow participants to maximize their training time when in class.
  3. Arrive at the in-person training with your own laptop computer with the latest version of MOVES2014a already installed and tested. Give yourself adequate time as “Administrative Rights” are needed to install the model. Course instructors will not be able to help with installation or resolve any installation problems on the day of the course. The MOVES2014a model, including instructions for downloading and installation, can be found at
    Questions about installing MOVES should be directed to
  4. Be sure to install MySQL Workbench when prompted during the MOVES installation process.
  5. Ensure that the laptop you bring also has MS Excel or some other Excel-compatible spreadsheet software.
  6. Download and unzip the 2018 3-Day PM Hot-spot Training Course (ZIP)(41 MB, May 2018) file to your laptop.Free ViewersThis important zip file contains the presentations and training materials for the course and should be downloaded, unzipped, and brought to class.
    • We recommend putting the unzipped folder on your desktop so that it is easily accessible during the training course.
    • Do not change the folder structure of the training materials, as that will make it difficult to find the appropriate files during the course.
    • Participants may want to bring paper copies of the course presentations and the packet of handouts in the ZIP file as they will not be provided. For the presentations, printing either 2 or 4 pages to a sheet is recommended.
Contents of the PM Hot-spot 3-day Training folder (ZIP file):
  • Presentations and Handouts. Contains presentations for all seven course modules and a class handout packet. It is recommended these be printed out and brought to the course (see above).
  • MOVES Files. Includes the MOVES run specifications, input, and output files used in the class. The MOVES model is not included in the download - see previous note about installing MOVES prior to class.
  • AERMOD Files. Includes the latest version of the AERMOD model (dated 16216r) and associated input and output files used in the course.
  • CAL3QHCR Files. Includes the latest approved version of the CAL3QHCR model (dated 13196) and associated input and output files used in the course. (Note that the in-person training will not cover the CAL3QHCR materials found in the course; they are provided for reference.)
  • Design Value Calculation Files. Includes spreadsheets with AERMOD output used to complete design values calculations for the example analyses.
  • Note that both AERMOD and CAL3QHCR models are included in the ZIP file. "Administrative rights" are not required to download or run these models.

Questions about installing MOVES should be directed to Questions about registering for individual classes or downloading the course materials should be directed to Laura Berry (
