Part 60, Subpart Cb, the emissions limits are hereby adopted and incorporated by reference except where the state may have established more stringent standards as specified in this subsection. An owner or operator may request that compliance with the following applicable emission standards be determined using carbon dioxide measurements corrected to an equivalent of seven (7) percent oxygen, determined in accordance with 40 C.F.R. Part 60, Subpart Eb.
(1)Particulate Matter. The emission limit for particulate matter contained in the gases discharged to the atmosphere from a designated unit is 25 milligrams per dry standard cubic meter, corrected to 7 percent oxygen.(2)Opacity. The emission limit for opacity exhibited by the gases discharged to the atmosphere from a designated unit is 10 percent (6-minute average).(3)Cadmium and Lead. The emission limit for cadmium contained in the gases discharged to the atmosphere from a designated unit is 0.035 milligrams per dry standard cubic meter, corrected to 7 percent oxygen. The emission limit for lead contained in the gases discharged to the atmosphere from a designated unit is 0.40 milligrams per dry standard cubic meter, corrected to 7 percent oxygen.(4)Mercury. The emission limit for mercury contained in the gases discharged to the atmosphere from a designated unit is 28 micrograms per dry standard cubic meter (µg/dscm), corrected to 7 percent oxygen or 15 percent of the potential mercury emission concentration (85 percent reduction by weight), corrected to 7 percent oxygen (dry basis), whichever is less stringent.(5)Sulfur Dioxide. The emission limit for sulfur dioxide contained in the gases discharged to the atmosphere from a designated unit is 29 parts per million by volume or 20 percent of the potential sulfur dioxide emission concentration (80 percent reduction by weight or volume), corrected to 7 percent oxygen (dry basis), whichever is less stringent. Compliance with this emission limit is based on a 24-hour daily geometric mean.(6)Hydrogen Chloride. The emission limit for hydrogen chloride contained in the gases discharged to the atmosphere from a designated unit is 29 parts per million by volume or 5 percent of the potential hydrogen chloride emission concentration (95 percent reduction by weight or volume), corrected to 7 percent oxygen (dry basis), whichever is less stringent.(7)Dioxins/Furans. The emission limit for dioxins/furans contained in the gases discharged to the atmosphere from a designated unit is 25 nanograms per dry standard cubic meter (total mass), corrected to 7 percent oxygen.(8)Nitrogen Oxides. The emission limits for nitrogen oxides shall be the limits specified in Table 1 of 40 C.F.R. Part 60, Subpart Cb. The averaging provisions specified in 40 C.F.R. Part 60, Subpart Cb shall apply.(9)Carbon Monoxide. The emission limits for carbon monoxide shall be the limits specified in Table 3 of 40 C.F.R. Part 60, Subpart Cb.(10)Fugitive Ash Visible Emissions. No owner or operator of are source recovery facility shall cause to be discharged to the atmosphere visible emissions of combustion ash from an ash conveying system (including conveyor transfer points and buildings or enclosures of ash conveying systems and storage areas) in excess of 5 percent of the observation period (i.e., 9 minutes in any 3-hour period), as determined by EPA Reference Method 22 in 40 C.F.R. Part 60, Appendix A. The provisions specified in this section do not apply during maintenance and repair of ash conveying systems.B.Operating Practices. The operating practices applicable to each large municipal waste combustor unit shall be the operating practices specified in 40 C.F.R. Part 60, Subpart Eb.C.Operator Training. The operator training and certification requirements of 40 C.F.R. Part 60, Subpart Eb shall apply to all facilities with large municipal waste combustor units. Compliance with these requirements shall be conducted according to the schedule specified in 40 C.F.R. Part 60, Subpart Cb.D.Compliance and Performance Testing Requirements. The compliance and performance testing requirements applicable to each large municipal waste combustor unit set forth in 40 C.F.R. Part 60, Subpart Eb except as provided for under 40 C.F.R. Part 60, Subpart B are hereby adopted and incorporated by reference. (1) When effluents from two or more affected units subject to the same standard are combined and exhausted through a common stack, the owner or operator may install a CEMS on each effluent or on the combined effluent. If the owner or operator elects to use one CEMS in a common stack, and the CEMS measures an exceedance of the emission standard, then the CEMS data shall represent an exceedance from each affected unit in operation at the time the exceedance was measured.(2) When effluents from two or more affected units subject to the same standard are combined and exhausted through a common stack, the owner or operator may conduct performance testing on each effluent or on the combined effluent. If the owner or operator elects to conduct performance testing in a common stack, and the performance test measures an exceedance of the emission standard, then the performance test data shall represent an exceedance from each affected unit in operation at the time the exceedance was measured.(a) For those affected units exhausting through a common stack and conducting a performance test for particulate matter, hydrogen chloride, lead, cadmium, mercury, and dioxins/furans, the following criteria shall be met in order to conduct performance testing in the common stack on the combined effluent: All affected units and emission controls shall be identical, units shall combust waste from the same waste stream, all affected units shall operate at the same unit load capacity during the performance test, and common stack testing shall be permitted only when the common stack test results measure below 50% of the emission limits in Section 5. A. When subsequent unit testing [or alternate demonstration] for any pollutant demonstrates compliance with the emission limits in Section 5. A, the facility may resume performance testing in the common stack.(3) The alternative performance testing schedule for dioxins/furans specified in 40 C.F.R. Part 60, Subpart Eb shall apply to large municipal waste combustor units where the performance tests for all affected units over a two-year period achieve a dioxins/furans emission level less than or equal to 15 nanograms per dry standard cubic meter total mass, corrected to 7 percent oxygen.(4) Initial Performance Test. Except for facilities where a retrofit was not required, which have conducted performance testing in accordance with the performance test methods specified in 40 C.F.R. Part 60, Subpart Eb, under similar operating conditions, within 12 months prior to the final compliance date; performance tests, as specified under 40 C.F.R. Part 60, Subpart A, shall be completed no later than 180 days after the final compliance date for the affected facility.(5) In addition to the performance testing required in 40 C.F.R. Part 60, Subpart Cb, large municipal waste combustor units shall conduct performance testing for the following metals: Emissions testing for arsenic, nickel, chromium, and beryllium shall be conducted using EPA Method 29 (40 C.F.R. Part 60, Appendix A). Testing shall be conducted according to a testing schedule consistent with 40 C.F.R. Part 60, Subpart Cb. In no case shall the interval between testing exceed three years.
E.Reporting, Record Keeping, and Compliance Schedules(1)Emissions Test Report Requirements. The reporting and record keeping requirements applicable to each large municipal waste combustor unit subject to this Chapter shall be the requirements as set forth in 40 C.F.R. Part 60, Subpart A, except for the siting requirements under 40 C.F.R. Part 60, Subpart Eb, and except for the following:(a) All reports required to be submitted under 40 C.F.R.
