For the purposes of applying the formulae provided in part 1200-3-24-.02(1)(c)2. means that distance up to five times the lesser of the height or the width dimension of a structure, but not greater than 0.8 km (1/2 mile), and.
The purpose of this regulation is to prevent the use of tall stacks or other dispersion techniques from affecting the emissions limitations required to meet National Air Quality Standards (NAAQS) or Prevention of Significant Deterioration (PSD) increments.
23 sty 2019 · Online calculator to find stack height based on good engineering practice. A stack is often a part of the emission control equipment used to ensure low ground level concentrations.
This guideline provides technical support for the definition and specification of GEP stack height as found in the stack height regulations for sources near building structures and for reasonable minimum stack heights. The remainder of this section contains applicable definitions of GEP stack height.
For tall buildings, where the width is less than the height, the stack height need only be equal to the height of the building plus 1.5 times it width. Thus, the good engineering practice stack height has been determined to be equal to the height of the structure plus 1.5 times the height or width, whichever is less.
At a distance of 0.8 km (1/2 mile) from the stack the height of the feature is at least 40 percent of the GEP (as determined by the formula in paragraph C.2 above) or 26 meters, whichever is greater; and
This document provides guidance on determining good engineering practice (GEP) stack height in accordance with the EPA's stack height regulations. It outlines the technical basis for the GEP stack height equation, including how building and terrain features can influence emissions.
