Section 096-121-7 - Small Municipal Waste Combustor Class I or Class II UnitsFor all resource recovery facilities, either Class I or Class II units, the following shall apply (except for periods of startup, shutdown, and malfunction) per 40 C.F.R. Part 60, Subpart BBBB:
A.Emission Limiting Standards. 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 7 percent oxygen. (1)Particulate Matter(a) For Class I units, emission limits for particulate matter are specified in Tables 2 and 3 of 40 C.F.R. Part 60, Subpart BBBB.(b) For Class II units, the emission limit for particulate matter contained in the gases discharged to the atmosphere is 23 milligrams per dry standard cubic meter, corrected to 7 percent oxygen. The averaging time is specified in Table 4 of 40 C.F.R. Part 60, Subpart BBBB.(2)OpacityThe emission limit for opacity exhibited by the gases discharged to the atmosphere from are source recovery unit is 10 percent (6-minute block average basis).
(3)Cadmium, Lead, Mercury, Nitrogen Oxides, and Dioxins/Furans(a) For Class I units, applicable emission limits for these pollutants are specified in Tables 2 and 3 of 40 C.F.R. Part 60, Subpart BBBB. For Class II units, the emission limits in the gases discharged to the atmosphere areas follows. These emission limits are all corrected to 7 percent oxygen.
i. Cadmium: 30 micrograms per dry standard cubic meter (dscm);ii. Lead: 660 micrograms per dry standard cubic meter;iii. Mercury: 28 micrograms per dry standard cubic meter 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;iv. Nitrogen Oxides: 315-330 parts per million by volume.(b)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.(4)Sulfur DioxideThe emission limit for sulfur dioxide contained in the gases discharged to the atmosphere from a Class I or a Class II resource recovery facility is 30 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.
(5)Hydrogen ChlorideThe emission limit for hydrogen chloride contained in the gases discharged to the atmosphere from a Class I or a Class II resource recovery facility is 25 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.
(6)Carbon MonoxideThe emission limitation for carbon monoxide, as measured at a location upstream of the control device, shall not exceed 100 parts per million (ppm) as an 8-hr running average corrected to 7 percent oxygen.
(7)Fugitive Ash Visible EmissionsNo 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 for Class I and Class II waste combustion units are specified in 40 C.F.R. Part 60, Subpart BBBB.C.Operator Training. Operator training and certification requirements of 40 C.F.R. Part 60, Subpart BBBB shall apply to all facilities with Class I or Class II municipal waste combustor units.D.Compliance and Performance Testing. The owner or operator of any applicable resource recovery facility shall prepare and submit to the Commissioner for approval a plan for performing tests required under this regulation. Such plan shall include, but is not limited to, sampling locations, test methods, sample analysis procedures, and quality assurance procedures. For any resource recovery facility which is issued an approved air emission license after the effective date of this regulation, the plan must be submitted ninety (90) days prior to the facility's start up. (1)Emission Testing Schedule. Testing required pursuant to this section shall be conducted in accordance with the following schedule:(a) Testing during the first two (2) years of operation must be conducted at least once in every 6-month period, with a minimum of three months between performance tests. The two year test period shall begin upon the Department's determination that the facility has begun commercial operation.(b) After the first two (2) years of operation, a test every twelve months is required with the following allowances: If all stack tests for a given pollutant over three consecutive years show compliance with the emission limit, the next subsequent stack test is required within 36 months of the anniversary of the third consecutive stack test showing compliance with the emission limit. There after, stack testing is required every third year but no later than 36 months following the previous stack test. If a stack test shows noncompliance with an emission limit, annual stack tests for that pollutant will then be required until all stack tests for three consecutive years show compliance with the emission limit for that pollutant. This provision applies to all pollutants subject to stack testing requirements per the applicable NSPS: dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash. Dioxins/furans stack testing may be required less often if the facility owns or operates multiple municipal waste combustion units and all municipal waste combustion units have demonstrated levels of dioxins/furans emissions less than or equal to 15 nanograms per dry standard cubic meter (total mass) for Class I units, or 30 nanograms per dry standard cubic meter (total mass) for Class II units, for two consecutive years. In that case, the facility may choose to conduct annual stack tests on only one municipal waste combustion unit per year per facility. If any annual stack test indicates levels of dioxins/furans emissions greater than the applicable level specified in this paragraph, subsequent annual stack tests are required on all municipal waste combustion units at a facility. A facility may return to testing one municipal waste combustion unit per year if dioxins/furans emissions levels are demonstrated to meet the applicable levels specified in this paragraph for all municipal waste combustion units at the facility for two consecutive years.
(c) Any alternative stack testing schedule must be submitted to the Department for preapproval and must meet the requirements of 40 C.F.R. Part 60, Subpart BBBB.(2)Emission Testing. The owner or operator of any applicable resource recovery facility shall conduct the following emission tests (all performance tests shall consist of three test runs):(a)Oxygen (or Carbon Dioxide). Emissions testing for oxygen (or carbon dioxide) shall be conducted using EPA Method 3A or 3B (40 C.F.R. Part 60, Appendix A).(b)Dioxins/Furans. Emissions testing for dioxins/furans emissions shall be conducted using EPA Method 23 (40 C.F.R. Part 60, Appendix A).(c)Hydrogen Chloride. Emissions testing for hydrogen chlorideshall be conducted using EPA Method 26 (40 C.F.R. Part 60, Appendix A).(d)Particulate Matter. Emissions testing for particulate matter shall be conducted using EPA Method 5 (40 C.F.R. Part 60, Appendix A).(e)Metals. Emissions testing for lead, cadmium, arsenic, nickel, mercury, beryllium, and chromium shall be conducted using EPA Method 29 (C.F.R. 40, Part 60, Appendix A).(f)Fugitive Emissions. Emissions testing for fugitive emissions shall be conducted using EPA Method 22 (40 C.F.R. Part 60, Appendix A).(3)Continuous Emissions Monitoring. Resource recovery facilities subject to this section must install and operate instruments for continuously monitoring carbon monoxide (CO) emissions, sulfur dioxide emissions (SO2), and opacity. An O2 or CO2 CEMS shall be calibrated, maintained, and operated at each location where the CO and SO2 CEMS are operated. When demonstrating compliance with the 80% reduction in SO2 emissions, SO2and diluent gas (O2 or CO2) shall be measured via CEMS at both the inlet and outlet of the control device. Continuous emissions monitoring instrumentation shall meet the requirements in 40 C.F.R. Part 60, Appendices B and F. E.Reporting and Recordkeeping(1) When continuous emission monitoring (CEM) or continuous opacity monitoring (COM) indicates that the limits in Section 7. A have been exceeded, the licensee shall document in writing the probable cause(s) for each exceeded emission limit and the corrective action taken after each exceeded emission limit in accordance with 06-096 C.M.R. ch. 117, Section 7. Continuous emissions monitoring data is to be retained by the owner or operator of the resource recovery facility for a minimum of six years.(2) All applicable reports shall be submitted to the Department on a quarterly basis within (30) days of the last date of the reporting period in accordance with 06-096 C.M.R. ch. 117, Section 7. (3) All emission and performance test reports shall be submitted to the Department within sixty (60) days from the date of test completion.06-096 C.M.R. ch. 121, § 7
