You must use results of stack tests for particulate matter, opacity, cadmium, lead, mercury, hydrogen chloride, dioxins/furans, and fugitive ash to demonstrate compliance with the applicable emission limits in Table 3 to Subpart WWWW. When calculating total dioxins/furans, zero may be used for congeners that are below the estimated detection limit (EDL). For estimated maximum possible concentration (EMPC) results, zero may be used when the EMPC is below the EDL, otherwise the EMPC must be used in determining total dioxins/furans. To demonstrate compliance for carbon monoxide, nitrogen oxides, and sulfur dioxide, see § 60.6470.
