Section Env-A 4303.01 - Emission Limits For Existing OSWI Units(a) Subject to (b), below, the emission limits for existing OSWI units shall be as specified in table 4303-1, below, for the listed air pollutants or parameters and all OSWI technologies: Table 4303-1: Emission Limits for All Existing OSWI Units
| Pollutant/Parameter | Emission Limitsa | Compliance Determinationb, c |
| Cadmium (Cd) | 18 micrograms per dry standard cubic meter (µg/dscm) | EPA Method 29 |
| Carbon Monoxide (CO) | 40 parts per million dry volume (ppmdv) | EPA Methods 10, 10A or 10B |
| Dioxins/Furans, total mass basis | 33 nanograms per dry standard cubic meter (ng/dscm) | EPA Method 23 |
| Hydrogen Chloride (HCl) | 15 ppmdv | EPA Method 26A |
| Lead (Pb) | 226 µg/dscm | EPA Method 29 |
| Mercury (Hg) | 74 µg/dscm | EPA Method 29 |
| Opacity | 10 percent | EPA Method 9 |
| Oxides of Nitrogen (NOx) | 103 ppmdv | EPA Methods 7, 7A, 7C, 7D or 7E d |

| Sulfur Dioxide (SO2) | 3.1 ppmdv | EPA Method 6 or 6C e |
(b) The following notes shall apply to table 4303-1: (1) The letter "a" shall indicate that all emission limits except opacity are measured at 7 percent oxygen, dry basis at standard conditions;(2) The letter "b" shall indicate that these methods are found in 40 CFR part 60, appendix A;(3) The letter "c" shall indicate that compliance with the CO emission limit is determined on a 12-hour rolling average basis using continuous emission monitoring system data;(4) The letter "d" shall indicate that ANSI/ASME PTC 19.10-1981-Part 10 is an acceptable alternative to Methods 7 and 7C only; and(5) The letter "e" shall indicate that ANSI/ASME PTC 19.10-1981-Part 10 is an acceptable alternative to Method 6 only.N.H.
