1 Analyses for polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-furans are required only for residues collected from areas downstream of the combustion chamber (e.g., ductwork, boiler tubes, heat exchange surfaces, air pollution control devices, etc.).

Note to the table:

Analysis is not required for those compounds that do not have an established F039 nonwastewater concentration limit.
