What’s Happening Now

EPA News

2018 Regional, State, and Local Modelers’ Workshop – As we mentioned last month, EPA has announced this year’s Regional, State, and Local Modelers’ Workshop (RSL) will be held at the EPA Region I offices in Boston from June 5-7. As usual, the first day of the workshop (June 5) will be open for public attendance. EPA has posted a registration link here and a draft agenda here.

Otherwise, we are still waiting to hear from EPA on for these upcoming nuggets:

  • EPA’s final Modeled Emission Rates for Precursors (MERP) guidance is due out in 2018
  • EPA is finalizing their Significant Impact Level (SIL) guidance for ozone and secondary PM2.5 and we should see that this year
  • Likewise, EPA’s final ozone / PM2.5 permit modeling guidance should come out in 2018
  • *A new version of AERSURFACE is due out in mid-2018 (maybe in time for the RSL workshop?)*

EPA has released a couple of Model Clearinghouse Concurrence Memoranda regarding modeling buoyant line sources. You can find both memos and supporting information related to them here and here.

Conferences and Workshops

Air & Waste Management Association

**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 is an update to EPA’s old 1990 New Source Review Workshop Manual (Draft). 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.

2018 AWMA Annual Conference and Exhibition – It’s time to start thinking about the AWMA’s Annual Conference and Exhibition (ACE)! This year’s premier environmental event will be held in Hartford, CT from June 25-28, 2018. This year’s theme is “Charting the Future – Environment, Energy, and Health”. For more information on agenda, registration, etc. go to https://www.awma.org/ace2018.

Other Conferences

CAPCA 2018 Spring Conference – The Carolinas Air Pollution Control Association’s (CAPCA) 2018 Spring Technical Workshop and Forum will be held April 11-13, 2018 at the Omni Grove Park Inn in Asheville, NC. This year’s special theme is “EPA: One Year Later”. For more information on registration, sponsorship / exhibitor opportunities, etc. click here.

TCEQ 2018 Environmental Trade Fair and Conference – It’s once again time for the Texas Commission on Environmental Quality’s (TCEQ’s) annual Environmental Trade Fair and Conference. It will be held May 15-16, 2018 at the Austin Convention Center. This event, one of the largest of its kind, promises to be full of great presentations on all media – air, water, and waste. We will be there, and hope to see you there, too! For more information on registration, agenda, and logistics, click here.

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!

Modeling Tip of the Month

This month’s tips have to do with pollutant names or IDs. First, did you know that BEEST allows you to have up to 500 different pollutant names in each BEEST session? Each pollutant name is limited to eight (8) characters, but they can include letters, numbers, underscores, and dashes (and even dots in a couple of special cases). Here’s tip #1: if you’re modeling speciated VOCs, use each compound’s Chemical Abstract Service (CAS) number as its ID. For example, if you’re modeling benzene, its CAS number is 71-43-2, and you could use an ID of “71-43-2” or “71432”. Both meet the pollutant naming conventions in AERMOD.

Not only that, but within AERMOD, certain pollutant IDs are used to process model outputs in a specific way. For example, if you are modeling SO2, you can have AERMOD provide you output based on the form of the 1-hour SO2 NAAQS. The form of the 1-hour SO2 NAAQS (at any given receptor) is the 99th percentile of the annual distribution of the daily maximum 1-hour SO2 concentration. To do this, simply call your pollutant “SO2” and select 1-hour averaging period and an output rank of 4th highest. Doing those three things tells AERMOD to produce the NAAQS design value for SO2. A similar pollutant-naming approach can be used for 1-hour NO2 NAAQS and 24-hour PM2.5 NAAQS:

  • 1-hour NO2 NAAQS: Pollutant ID must be “NO2” (plus 1-hour averaging period and 8th high rank)
  • 24-hour PM2.5 NAAQS: Pollutant ID can be “PM25”, “PM2.5”, “PM-25”, or “PM-2.5” (plus 24-hour averaging period and 8th high rank)

**Keep watching this newsletter and our website in 2018 for something brand new that will make modeling even easier.**

Advanced AERMOD

Our next Advanced AERMOD class is going to be August 2-3, 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
  • AERSCREEN
  • Changes related to the new Appendix W (Guideline on Air Quality Models)
  • MAXIFILE and ARRAY2 processing
  • AERMOD beta options, such as PSDCREDIT

2018 Class Schedule

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

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

BeestXpress users now have some great new 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

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/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 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 last time we counted, it was somewhere in the neighborhood of 250 years’ worth of experience. The kinds of 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 non-attainment 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.
