Abstract

Lays out a relatively simple, non-specific method of approximately determining the heights of discharge stacks for polluting emissions, which should be adequate in normal circumstances. It is intended for use by inspectors, local authorities, industry and others who have a need to make such calculations, although it is primarily intended for use with those processes regulated by local authorities.
