We’ve Got a New Website

Posted by on Tuesday, August 14th, 2018 in Newsletters

What’s Happening Now

Our New Website is Here!

For years, you’ve used www.beeline-software.com to access our software updates and you’ve used www.oris-solutions.com to register for training classes. So, in the spirit of “one-stop shopping”, we’ve built a new website that combines these two needs into one state of the art site. The new URL is www.providenceoris.com, and we encourage you to pay a visit and add it to your browser bookmarks.

EPA News

No real EPA news since June – although we’re all anxiously anticipating the release of a new draft version of AERSURFACE.

Conferences and Workshops

Air & Waste Management Association

AWMA Dispersion Modeling Specialty Conference – It was announced at the June 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.

Other Events

Texas Commission on Environmental Quality’s Autumn Environmental Quality Conference and Expo – The TCEQ’s new Autumn Environmental Conference and Expo combines the former Advanced Air Permitting and Water Quality/Stormwater Seminars and includes a one-day Waste Classification Workshop. This event will be October 9‑11, 2018 and will be held at the Palmer Events Center in Austin, Texas. For more information regarding agenda, registration, hotels, etc. check out https://www.tceq.texas.gov/p2/events/autumn-environmental-conference-and-expo-1.

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 info@oris-solutions.com, and we’ll be happy to include it.

Simply the Best!

→ First in a series on this new software product

Although users generally don’t process meteorological data via AERMET as often as they run AERMOD, meteorological data processing can nevertheless be a crucial part of a modeling project – especially when *YOU* have to do it. With that being said, the first question invariably is, what kind of data do I need and where do I find it? AERMOD Wizard has the answer! With this new tool, you can view your area of interest on a map and see all the nearby meteorological stations. Then, when you have decided which station and year(s) are needed, all it takes is a handful of clicks to have AERMOD Wizard go out and automatically download the raw meteorological data for you – whether it’s surface station data (integrated surface hourly data (ISHD) format), upper air data (Forecast Systems Lab (FSL) format), and/or 1- and 5-minute Automated Surface Observation System (ASOS) surface wind data, AERMOD Wizard can grab it all. Not only that, but you can then call/invoke AERMET and AERMINUTE from AERMOD Wizard to start processing your newly downloaded data sets.

Check back here next month when we discuss AERMOD Wizard‘s utility regarding ambient monitoring data and generating background data for input to AERMOD.

* 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

If you are processing Automated Surface Observation System (ASOS) through the AERMINUTE system, you know that one of the required output files is the HOURFILE, which includes the arithmetic-averaged wind speeds and unit vector-averaged wind directions for each hour. The HOURFILE is then incorporated during Stage 2 of AERMET. If, by chance, you happen to forget the name you assigned to HOURFILE, you can easily find it within your Windows File Explorer/directory by looking for the file that is 242 KB is size (or 243 KB for a leap year).

“Our expertise is contagious. Catch it!”

AERMOD Modeling for Permits

Our last scheduled AERMOD Modeling for Permits class for 2018 will be November 13‑14. As usual, it will be at our training facility at our Austin, Texas office. Register today and plan to join us in the Live Music Capital of the World! Click here to register!

Advanced AERMOD

Similarly, our last Advanced AERMOD class of the year is going to be November 15‑16, also at our Austin office. This popular course covers those topics that are near and dear to modelers, such as:

  • NAAQS modeling for 1-hour NO2, 1-hour SO2 and 24-hour PM2.5 (including the new MaxDCont Viewer)
  • Meteorological data processing with AERMET / AERMINUTE / AERSURFACE
  • Changes related to the new Appendix W (Guideline on Air Quality Models)
  • MAXIFILE and ARRAY2 processing
  • AERMOD alpha options, such as PSDCREDIT

So, get your “Keep Austin Weird” vibe on and join us by registering for Advanced AERMOD by going here.

2019 Class Schedule

As promised, here’s our tentative list of AERMOD classes for 2019:

Class Dates Location
AERMOD Modeling for Permits February 26 – 27 Austin, TX
Advanced AERMOD February 28 – March 1 Austin, TX
AERMOD Modeling for Permits April 23 – 24 Austin, TX

**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 www.beestxpress.com 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!

Meteorological Data Processing Services

Do you need AERMOD-ready or CalPuff-ready meteorological data? If so, we can help! Whether it’s running the AERMET / AERMINUTE system or a full CalMet run, Providence 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 info@oris-solutions.com or jamesred@providenceeng.com.

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. Feel free to contact us at (512) 258-8855 or info@oris-solutions.com.
