Technical Report ·
OSTI ID:5800207
This manual is to be used by students who are learning how to evaluate ('read') visible emissions to the atmosphere from air pollution sources. Both black, grey, and white plumes are covered. The manual discusses sources of air pollution and describes visible emissions to be expected and the reasons why such may occur. A brief review of meteorological phenomena affecting stack plume behavior is given. Practices and procedures to be used in evaluating visible emissions of both the black/grey and other color nature are described in detail. The Ringelmann chart and its use are discussed. Equipment for generating visible emissions to be observed in training observers is described in detail.
