For the following pollutants You must meet the following emission limitsb Using the following averaging times And determine compliance by the following methods 1. Organics: Dioxins/Furans (total mass basis) 30 nanograms per dry standard cubic meter for municipal waste combustion units that do not employ an electrostatic precipitator-based emission control system -or- 3-run average (minimum run duration is 4 hours) Stack test. 60 nanograms per dry standard cubic meter for municipal waste combustion units that employ an electrostatic precipitator-based emission control system 2. Metals: Cadmium 0.040 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test. Lead 0.490 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test. Mercury 0.080 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test. 85 percent reduction of potential mercury emissions Opacity 10 percent Thirty 6-minute averages Stack test. Particulate Matter 27 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test. 3. Acid Gases: Hydrogen Chloride 31 parts per million by dry volume 95 percent reduction of potential hydrogen chloride emissions 3-run average (minimum run duration is 1 hour) Stack test. Sulfur Dioxide 31 parts per million by dry volume 75 percent reduction of potential sulfur dioxide emissions 24-hour daily block geometric average concentration percent reduction Continuous emission monitoring system. 4.
