Where: CFWA = Flow-weighted average concentration of all process vents.
n = Number of process vents.
Fi = Flow rate from process vent i in dry standard cubic feet per minute, as measured during the most recent compliance test.
Ci = Concentration of lead in process vent i, as measured during the most recent compliance test.
Emission Unit | Total Hydrocarbon (Parts per million by volume expressed as propane corrected to four percent (4%) carbon dioxide) | Dioxin and furan (nanograms per dry standard cubic meter expressed as toxic equivalency quotient (TEQ) corrected to seven percent (7%) oxygen) |
