Individual Accuracy in Estimating Plume Opacity
WebMethod 9 states that Opacity observations shall be made at the point of greatest opacity in the portion of the plume where condensed water vapor is not present. When Water Vapor or Steam Are Not Present When a plume does not have water vapor or steam, finding the point to read is simple, read at the point of the densest smoke.

Region 7 Policy on Periodic Monitoring for Opacity
WebMethod 9 requires that the observer (sometimes called a smoke reader) be trained and certified by an accredited training organization in the method. Often these organizations refer to this training as “smoke school”. Only certified personnel are legally allowed to conduct the test. WebMethod 9 does not contain any special requirements or specifications for equipment or supplies. However, certain equipment is necessary to conduct a valid observation that will withstand the rigors of litigation. Experience gained from litigation has shown that accurate, high-quality equipment is essential for valid observations. WebOpacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light.In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc.An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing … cloudland high school football schedule
