If At First You Don’t Succeed, Refine
To simplify, and expedite an air quality analysis (AQA), a rough first pass is typical when performing dispersion modeling. If the first pass doesn’t show compliance, additional refinements are in order. When trying to demonstrate compliance with the NO2 1-hour NAAQS, there are quite a few refinement options available. On July 7th, 2021 at noon…Continue Reading
NOx Shouldn’t Mean No
When the 1-hour nitrogen dioxide (NO2) NAAQS became effective in 2010, demonstrating compliance with the NO2 NAAQS, became a whole lot more difficult. Passing the annual standard was almost no problem at all, but the 1-hour standard was a bit problematic. On June 30th, 2021 at noon CDT, join us for a FREE LIVE webinar…Continue Reading
The Whole Problem
Americans constantly complain that completing their federal income tax return is too complicated and takes too long. Americans spend, on average, 13 hours to complete their federal tax returns. The 13 hours is broken down this way: • 6 hours to compile information ( W-2, 1099-INT, 1099-R, 1099-MISC, 1098, 1098-T, K-1, etc.) • 4 hours…Continue Reading

Staff tasked to…Continue Reading

The story is meant to draw you in so that an otherwise really dry subject seems a little bit interesting and relatable. For this article, I have decided not to do that because the issues involved are too…Continue Reading
Dispersion Modeling Audits: Using NK Tools
Neil Armstrong and Buzz Aldrin landing and walking on the moon was quite an achievement. Though the ultimate goal was to put humans on the moon, the steps to get to that end point didn’t exactly resemble the final product. The beginning stages of the preparation for the moonshot were very crude, clumsy, and addressed…Continue Reading
Dispersion Modeling Audits: Model Results and Other Issues
On October 9th, 2018, the Texas Commission on Environmental Quality (TCEQ) announced and introduced its plan to expedite air quality permit application reviews at its Autumn Environmental Conference. TCEQ rolled out spreadsheet workbook templates that would take the place of many of the forms required for an air quality permit application. The rationale for the…Continue Reading
How To Improve Your Air Quality Analysis Report: Part 3- Input Data Tables
Have you ever gone to the grocery store for a specific flavor of canned soup? I find myself stepping as far back as the aisle allows so I can see all one million flavors of soup and isolate the one I am looking for. It takes a few minutes to scan through all of the…Continue Reading
Which Is Right for Your AERMOD Project: POINT, POINTCAP, & POINTHOR?
Henry Ford once said, “a customer can have a car painted any color he wants as long as it’s black”? There were several reasons why that was, but still, there wasn’t much of a choice. The was true when representing a stack or a vent in AERMOD. Whether the vent exhausted vertically, horizontally, or radially…Continue Reading
