What’s Happening Now

EPA News

No real EPA news since last month – we’re all still digesting the information and presentations from last month’s Regional, State, and Local (RSL) Modelers’ Workshop.

However, we are now hearing that next year’s EPA RSL workshop will be held in Seattle, WA. No date has been set yet.

If you are interested in the information presented at this year’s RSL workshop, you may view PDFs of all the presentations here.

Conferences and Workshops

Air & Waste Management Association

2018 AWMA Annual Conference and Exhibition – As always, it is a genuine thrill for us to meet and greet our customers and friends at the Annual Conference and Exhibition (ACE). We hope that you enjoyed the conference and enjoyed spending some of your time there visiting us at our booth. We also hope you enjoyed our demo of AERMOD Wizard. (See more about this under Providence Products!)

Since next year’s conference is never that far off, let’s make plans to meet in Quebec City, Quebec, Canada June 25‑28, 2019 for ACE 2019! Read more about it here.

AWMA Dispersion Modeling Specialty Conference – It was announced at the last month’s meeting of the AWMA Air Pollution Modeling committee (held during ACE) that the next of AWMA’s series of dispersion modeling specialty conferences will be held in the spring of 2019 – probably late March – early April time frame somewhere in the Research Triangle Park, NC area. Look for a call for papers later this summer.

**New Source Review Workshop Manual** – If you do New Source Review air permitting (and/or modeling), please note that AWMA’s New Source Review Manual is now available! This new version is available online in an interactive, hyperlinked and searchable format. It covers all the big NSR-related topics, such as PSD / nonattainment applicability, BACT, air quality analysis, and modeling. Check here for details.

If your company, organization, agency, State, etc. has an upcoming modeling or air quality-related event and you’d like it publicized in Providence/Oris Notes, please send that information to us at, and we’ll be happy to include it.

Simply the Best!


BEEST 11.12 was released May 18, 2018. This new version includes:

  • BEEST now fully supports AERMOD version 18081
  • BEEST now fully supports AERMAP version 18081
  • Our AerMet interface fully supports AERMET version 18081

Professional CalPuff

Our most recent version of Professional CalPuff (4.00) was released August 26, 2016 and is available to all registered users with current maintenance.

Users in maintenance can download the most recent version of Professional CalPuff from | Support | Software Updates.


If you came by our booth at AWMA ACE last month, you were treated to a sneak preview of our latest software offering, AERMOD Wizard! Using a map-based user interface, this nifty piece of software will help you with the following tasks:

  • Automatically go out and download raw meteorological data – surface (integrated surface hourly data (ISHD) format), upper air (Forecast Systems Lab (FSL) format), and 1- and 5-minute Automated Surface Observation System (ASOS) surface wind data
  • From within AERMOD Wizard, you can also call / invoke AERMET and AERMINUTE to process your downloaded meteorological data
  • Automatically go out and download ambient monitoring data for NO2, CO, PM-10, PM-2.5, SO2, and ozone
  • Read the downloaded ambient data and automatically create an AERMOD-ready background data file in any number of temporal formats (e.g. SEASHR, HROFDAY, MHRDOW7, etc). These can be copied directly into BEEST or written as an external AERMOD SO formatted text file.
  • Wind roses can be generated from the meteorological data
  • Pollution roses can be generated from the ambient and meteorological data
  • Wind roses and pollutant roses can be exported to Google Earth
  • Input source emission rates of visibility-obscuring pollutants (SO2, NOX, PM-10, H2SO4) and automatically do Class I area Q / D analyses
  • And more cool features to come in the future!

We anticipate launching / releasing AERMOD Wizard by the end of this summer. Watch this newsletter and our website for more information on the release, plus release-related events and webinars.

* We’re off to see the Wizard! *

If you have suggestions for an enhancement to any of our modeling software products, please let us know and we’ll do our best to incorporate it into the software ASAP!

Modeling Tip of the Month

Sometimes we find that we need to model the impacts of two facilities that are separated by more than a kilometer or so. For separations on the order of 10 km or more, you can still have BEEST generate a tiered grid (tight receptors close in, coarser spacing going further out), but it may generate more tightly-spaced receptors than you really need – which increases run times! Here’s a neat workaround you can use:

  1. Copy the coordinates for both property lines to a temporary Excel file.
  2. Remove all receptors and remove property line 2, leaving property line 1 in BEEST.
  3. Generate a receptor grid around property line 1.
  4. Convert the receptors to discrete receptors.
  5. Copy the receptors to a temporary Excel file.
  6. Remove all receptors and remove property line 1.
  7. Add property line 2 to BEEST.
  8. Generate a receptor grid around property line 2.
  9. Convert the receptors to discrete receptors.
  10. Copy the receptors to the same temporary Excel file you used in step 5.
  11. Remove all receptors and add property line 1 to BEEST.
  12. Now, both property lines are in BEEST but all receptors are in Excel.
  13. Use the “Remove Duplicates” button in Excel to remove overlapping receptor coordinates.
  14. Copy all receptors from Excel into BEEST.
  15. If any receptors are inside the property lines, remove them manually.

2018 Class Schedule

Here’s the last set of our scheduled AERMOD classes for 2018:

Class Dates Location
AERMOD Modeling for Permits November 13-14 Austin, TX
Advanced AERMOD November 15-16 Austin, TX

We will be posting our 2019 schedule of training classes within the next couple of months.

**Don’t forget, if our schedule of classes doesn’t mesh with your schedule, or if you have several people that need to be trained at once, contact us about setting up an on-site class. Have laptop, will travel!**


**BeestXpress has been upgraded to run AERMOD 18081**

In addition, BeestXpress users have some great system enhancements to work with:

  • The “Job Details” webpage now displays the pollutant being modeled;
  • The “Job Details” webpage now displays run progress for MAXDCONT calculations;
  • Modeling runs with multiple partitions now include a combined AERMOD input file (*.DTA) in the output .ZIP file;
  • Added an option to the “Submit Job” webpage that affects modeling runs with multiple partitions: the intermediate output files created by each partition can be omitted from the output .ZIP file
  • The “Job Search” webpage now includes the option to search by project number
  • Users have access to up to 50 partitions per AERMOD run

We’re also excited to note the BeestXpress has now processed over 300,000 AERMOD runs. Wow!

If you’ve never used BeestXpress, or it has been a while since you did, you may want to log on at to take advantage of our AERMOD “force multiplier”. That AERMOD run that might have taken a day to run on your desktop computer can finish in an hour or less on BeestXpress. When time is money, BeestXpress is the best modeling return on investment there is!

Whether it’s running the AERMET / AERMINUTE system or a full CalMet run, Providence/Oris has the background, know-how, and experience to have your data processed and ready for you ASAP. Need on-site data processed? We do that, too! If you’d like more information, contact us at or

Consulting Solutions

One thing that we’re very proud of is the depth and range of our modeling experience and expertise. The kinds of air quality models we’ve used include all types, ranging from simple screening tools like SCREEN and AERSCREEN to plume models like ISC and AERMOD to CalPuff to CAMx. The types of analyses included basic Significant Impact Level, NAAQS, PSD increment consumption, Class I analyses, air toxics, and SIP attainment demonstrations. Most recently, we have begun conducting nonattainment permit inter-pollutant trading (NOx for VOC) modeling using CAMx. So, we’ve seen it all. To that end, should you or your clients need additional modeling assistance or just a second set of eyes to QA or peer review your modeling (ranging from initial protocol up to final submission), we stand ready to help.
