| Sulfur dioxide | 720 parts per million dry volume | Biomass-7.3 parts per million dry volume Coal-850 parts per million dry volume |
3-run average (for Method 6, collect a minimum of 60 liters, for Method 6C,1 hour minimum sample time per run) | Performance test (Method 6 or 6C at 40 CFR part 60, appendix A-4). |
1All emission limitations are measured at 7 percent oxygen, dry basis at standard conditions. For dioxins/furans, you must meet either the Total Mass Basis limit or the toxic equivalency basis limit.
2In lieu of performance testing, you may use a CEMS or, for mercury, an integrated sorbent trap monitoring system to demonstrate initial and continuing compliance with an emissions limit, as long as you comply with the CEMS or integrated sorbent trap monitoring system requirements applicable to the specific pollutant in §§60.2145 and 60.2165. As prescribed in §60.2145(u), if you use a CEMS or an integrated sorbent trap monitoring system to demonstrate compliance with an emissions limit, your averaging time is a 30-day rolling average of 1-hour arithmetic average emission concentrations.
