Be Explicit, But Don’t Double Count
To demonstrate compliance with the NAAQS, you need to account for ALL emission sources. The impact of those sources that is not already included in the monitored background concentrations need to be explicitly included in your dispersion modeling analysis. How do you determine which sources are included in the monitored values and which ones are…

Give Yourself Flexibility
Golfers typically use a variety of clubs: a putter, a driver or two, and a pitching wedge. You could get by with just one club, but why limit yourself. When representing, say, a boiler in your dispersion modeling analysis, why represent the boiler in just one way if it can burn a variety of fuels….

Modeling The Unplanned
Unplanned events happen. Things break. Equipment fails. If the unexpected incident triggers 30 TAC 101.201 of the “emission event rules” then you may be required to perform dispersion modeling. On July 14th, 2021 at noon CDT, join us for a FREE LIVE webinar as we explain the nuances and details to be aware of to…

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…

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…

A $1,000 Saved is a $1,000 Earned
In business, the most important performance metric is the bottom line. Though market forces are beyond your control, the one factor that is within your control is productivity (product per time). If you could produce the same amount of product in less time, what would it be worth to you? From my own experience and…

NK Tools – Part 4 Permit Data and Permit Files
An air quality permit can be a very complex document. Many operational limitations represented in the permit can be very straightforward while others can be nuanced. If you are trying to develop a permitting strategy, accurately represent the permit limitations, or determine if a permit representation is accurate, you need access to the source documents…

Emissions and Monitoring Data at Your Fingertips
The first step in preparing an air quality permit application is to determine whether the proposed project triggers federal permitting requirements. To make that determination, you need access to actual emissions data typically reported through an emissions inventory. How do you do that? If the proposed project involves a net increase in criteria pollutant emissions…
Continue ReadingWhy Are You Wasting Your Time and Your Client’s Money?
How much time do you spend creating an “area map” for your air quality permit application or dispersion modeling submittal? The short answer is too much. The purpose of providing an area map is to provide to the regulator (and the public) information about where the proposed permitted site is or will be and what…

Required Data Quick, Easy, and Documented
Every dispersion modeling analysis requires land cover (rural or urban), terrain, and meteorological (met) data as input. For analyzing land cover data, EPA suggests two methods: Auer land use and population density methods. One method can give you a rural setting right in the middle of New York City and the other indicating the Houston…
