(f) If you prefer to use an alternative sulfur dioxide monitoring method, such as parametric monitoring, or cannot monitor emissions at the inlet of the air pollution control device to determine percent reduction, you can apply to the Administrator for approval to use an alternative monitoring method under §60.13(i) of subpart A of 40 CFR part 60.
§ 62.15180 How are the data from the continuous emission monitoring systems used?
top
You must use data from the continuous emission monitoring systems for sulfur dioxide, nitrogen oxides, and carbon monoxide to demonstrate continuous compliance with the applicable emission limits specified in tables 2, 3, 4, and 5 of this subpart. To demonstrate compliance for dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash, see §62.15235.
§ 62.15185 How do I make sure my continuous emission monitoring systems are operating correctly?
top
(a) Conduct initial, daily, quarterly, and annual evaluations of your continuous emission monitoring systems that measure oxygen (or carbon dioxide), sulfur dioxide, nitrogen oxides (Class I municipal waste combustion units only), and carbon monoxide.
(b) Complete your initial evaluation of the continuous emission monitoring systems within 180 days after your final compliance date.
(c) For initial and annual evaluations, collect data concurrently (or within 30 to 60 minutes) using your oxygen (or carbon dioxide) continuous emission monitoring system, your sulfur dioxide, nitrogen oxides, or carbon monoxide continuous emission monitoring systems, as appropriate, and the appropriate test methods specified in table 6 of this subpart. Collect these data during each initial and annual evaluation of your continuous emission monitoring systems following the applicable performance specifications in appendix B of 40 CFR part 60. Table 7 of this subpart shows the performance specifications that apply to each continuous emission monitoring system.
(d) Follow the quality assurance procedures in Procedure 1 of appendix F of 40 CFR part 60 for each continuous emission monitoring system. These procedures include daily calibration drift and quarterly accuracy determinations.
§ 62.15190 Am I exempt from any 40 CFR part 60 appendix B or appendix F requirements to evaluate continuous emission monitoring systems?
top
Yes, the accuracy tests for your sulfur dioxide continuous emission monitoring system require you to also evaluate your oxygen (or carbon dioxide) continuous emission monitoring system. Therefore, your oxygen (or carbon dioxide) continuous emission monitoring system is exempt from two requirements:
(a) Section 2.3 of Performance Specification 3 in appendix B of 40 CFR part 60 (relative accuracy requirement).
(b) Section 5.1.1 of appendix F of 40 CFR part 60 (relative accuracy test audit).
§ 62.15195 What is my schedule for evaluating continuous emission monitoring systems?
top
(a) Conduct annual evaluations of your continuous emission monitoring systems no more than 13 months after the previous evaluation was conducted.
(b) Evaluate your continuous emission monitoring systems daily and quarterly as specified in appendix F of 40 CFR part 60.
§ 62.15200 What must I do if I choose to monitor carbon dioxide instead of oxygen as a diluent gas?
top
You must establish the relationship between oxygen and carbon dioxide during the initial evaluation of your continuous emission monitoring system. You may reestablish the relationship during annual evaluations. To establish the relationship use three procedures:
(a) Use EPA Reference Method 3A or 3B in Appendix A of 40 CFR part 60 to determine oxygen concentration at the location of your carbon dioxide monitor.
(b) Conduct at least three test runs for oxygen. Make sure each test run represents a 1-hour average and that sampling continues for at least 30 minutes in each hour.
(c) Use the fuel-factor equation in EPA Reference Method 3B to determine the relationship between oxygen and carbon dioxide.
§ 62.15205 What minimum amount of monitoring data must I collect with my continuous emission monitoring systems and is this requirement enforceable?
top
(a) Where continuous emission monitoring systems are required, obtain 1-hour arithmetic averages. Make sure the averages for sulfur dioxide, nitrogen oxides (Class I municipal waste combustion units only), and carbon monoxide are in parts per million by dry volume at 7 percent oxygen (or the equivalent carbon dioxide level). Use the 1-hour averages of oxygen (or carbon dioxide) data from your continuous emission monitoring system to determine the actual oxygen (or carbon dioxide) level and to calculate emissions at 7 percent oxygen (or the equivalent carbon dioxide level).
(b) Obtain at least two data points per hour in order to calculate a valid 1-hour arithmetic average. Section 60.13(e)(2) of subpart A of 40 CFR part 60 requires your continuous emission monitoring systems to complete at least one cycle of operation (sampling, analyzing, and data recording) for each 15-minute period.
(c) Obtain valid 1-hour averages for 75 percent of the operating hours per day for 90 percent of the operating days per calendar quarter. An operating day is any day the unit combusts any municipal solid waste or refuse-derived fuel.
(d) If you do not obtain the minimum data required in paragraphs (a) through (c) of this section, you are in violation of this data collection requirement regardless of the emission level monitored, and you must notify the Administrator according to §62.15340(e).
(e) If you do not obtain the minimum data required in paragraphs (a) through (c) of this section, you must still use all valid data from the continuous emission monitoring systems in calculating emission concentrations and percent reductions in accordance with §62.15210.
§ 62.15210 How do I convert my 1-hour arithmetic averages into appropriate averaging times and units?
top
(a) Use the equation in §62.15390(a) to calculate emissions at 7 percent oxygen.
(b) Use EPA Reference Method 19 in Appendix A of 40 CFR part 60, section 4.3, to calculate the daily geometric average concentrations of sulfur dioxide emissions. If you are monitoring the percent reduction of sulfur dioxide, use EPA Reference Method 19, section 5.4, to determine the daily geometric average percent reduction of potential sulfur dioxide emissions.
(c) If you operate a Class I municipal waste combustion unit, use EPA Reference Method 19, section 4.1, to calculate the daily arithmetic average for concentrations of nitrogen oxides.
(d) Use EPA Reference Method 19, section 4.1, to calculate the 4-hour or 24-hour daily block averages (as applicable) for concentrations of carbon monoxide.
§ 62.15215 What is required for my continuous opacity monitoring system and how are the data used?
top
(a) Install, calibrate, maintain, and operate a continuous opacity monitoring system.
(b) Install, evaluate, and operate each continuous opacity monitoring system according to §60.13 of subpart A 40 CFR part 60.
(c) Complete an initial evaluation of your continuous opacity monitoring system according to Performance Specification 1 in appendix B of 40 CFR part 60. Complete this evaluation by 180 days after your final compliance date.
(d) Complete each annual evaluation of your continuous opacity monitoring system no more than 13 months after the previous evaluation.
(e) Use tests conducted according to EPA Reference Method 9, as specified in §62.15245, to determine compliance with the applicable opacity limit in tables 2 or 4 of this subpart. The data obtained from your continuous opacity monitoring system are not used to determine compliance with the opacity limit.
§ 62.15220 What additional requirements must I meet for the operation of my continuous emission monitoring systems and continuous opacity monitoring system?
top
Use the required span values and applicable performance specifications in table 8 of this subpart.
§ 62.15225 What must I do if my continuous emission monitoring system is temporarily unavailable to meet the data collection requirements?
top
Refer to table 8 of this subpart. It shows alternate methods for collecting data when these systems malfunction or when repairs, calibration checks, or zero and span checks keep you from collecting the minimum amount of data.
Stack Testing
top
§ 62.15230 What types of stack tests must I conduct?
top
Conduct initial and annual stack tests to measure the emission levels of dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash.
§ 62.15235 How are the stack test data used?
top
You must use results of stack tests for dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash to demonstrate compliance with the applicable emission limits in tables 2 and 4 of this subpart. To demonstrate compliance for carbon monoxide, nitrogen oxides, and sulfur dioxide, see §62.15180.
§ 62.15240 What schedule must I follow for the stack testing?
top
(a) Conduct initial stack tests for the pollutants listed in §62.15230 by 180 days after your final compliance date.
(b) Conduct annual stack tests for these pollutants after the initial stack test. Conduct each annual stack test no later than 13 months after the previous stack test.
§ 62.15245 What test methods must I use to stack test?
top
(a) Follow table 8 of this subpart to establish the sampling location and to determine pollutant concentrations, number of traverse points, individual test methods, and other specific testing requirements for the different pollutants.
(b) Make sure that stack tests for all these pollutants consist of at least three test runs, as specified in §60.8 (Performance Tests) of subpart A of 40 CFR part 60. Use the average of the pollutant emission concentrations from the three test runs to determine compliance with the applicable emission limits in tables 2 and 4 of this subpart.
(c) Obtain an oxygen (or carbon dioxide) measurement at the same time as your pollutant measurements to determine diluent gas levels, as specified in §62.15175.
(d) Use the equations in §62.15390(a) to calculate emission levels at 7 percent oxygen (or an equivalent carbon dioxide basis), the percent reduction in potential hydrogen chloride emissions, and the reduction efficiency for mercury emissions. See the individual test methods in table 6 of this subpart for other required equations.
(e) You can apply to the Administrator for approval under §60.8(b) of subpart A of 40 CFR part 60 to
(1) Use a reference method with minor changes in methodology;
(2) Use an equivalent method;
(3) Use an alternative method the results of which the Administrator has determined are adequate for demonstrating compliance;
(4) Waive the requirement for a performance test because you have demonstrated by other means that you are in compliance; or
(5) Use a shorter sampling time or smaller sampling volume.
§ 62.15250 May I conduct stack testing less often?
top
(a) You may test less often if you own or operate a Class II municipal waste combustion unit and if all stack tests for a given pollutant over 3 consecutive years show you comply with the emission limit. In this case, you are not required to conduct a stack test for that pollutant for the next 2 years. However, you must conduct another stack test within 36 months of the anniversary date of the third consecutive stack test that shows you comply with the emission limit. Thereafter, you must perform stack tests every third year but no later than 36 months following the previous stack tests. If a stack test shows noncompliance with an emission limit, you must conduct annual stack tests for that pollutant until all stack tests over 3 consecutive years show compliance with the emission limit for that pollutant. This provision applies to all pollutants subject to stack testing requirements: dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash.
(b) You can test less often for dioxins/furans emissions if you own or operate a municipal waste combustion plant that meets two conditions. First, you have multiple municipal waste combustion units onsite that are subject to this subpart. Second, all these 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 2 consecutive years. In this case, you may choose to conduct annual stack tests on only one municipal waste combustion unit per year at your plant. This provision only applies to stack testing for dioxins/furans emissions.
(1) Conduct the stack test no more than 13 months following a stack test on any municipal waste combustion unit subject to this subpart at your plant. Each year, test a different municipal waste combustion unit subject to this subpart and test all municipal waste combustion units subject to this subpart in a sequence that you determine. Once you determine a testing sequence, it must not be changed without approval by the Administrator.
(2) If each annual stack test shows 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, you may continue stack tests on only one municipal waste combustion unit subject to this subpart per year.
(3) If any annual stack test indicates levels of dioxins/furans emissions greater than 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, conduct subsequent annual stack tests on all municipal waste combustion units subject to this subpart at your plant. You may return to testing one municipal waste combustion unit subject to this subpart per year if you can demonstrate dioxins/furans emission levels 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 all municipal waste combustion units at your plant subject to this subpart for 2 consecutive years.
§ 62.15255 May I deviate from the 13-month testing schedule if unforeseen circumstances arise?
top
You may not deviate from the 13-month testing schedules specified in §§62.15240(b) and 62.15250(b)(1) unless you apply to the Administrator for an alternative schedule, and the Administrator approves your request for alternate scheduling prior to the date on which you would otherwise have been required to conduct the next stack test.

Air Curtain Incinerators that Burn 100 Percent Yard Waste
top
§ 62.15365 What is an air curtain incinerator?
top
An air curtain incinerator operates by forcefully projecting a curtain of air across an open chamber or open pit in which combustion occurs. Incinerators of this type can be constructed above or below ground and with or without refractory walls and floor.
§ 62.15370 What is yard waste?
top
Yard waste is grass, grass clippings, bushes, shrubs, and clippings from bushes and shrubs. They come from residential, commercial/retail, institutional, or industrial sources as part of maintaining yards or other private or public lands. Yard waste does not include two items:
(a) Construction, renovation, and demolition wastes that are exempt from the definition of “municipal solid waste” in §62.15410.
(b) Clean wood that is exempt from the definition of “municipal solid waste” in §62.15410 of this subpart.
§ 62.15375 What are the emission limits for air curtain incinerators that burn 100 percent yard waste?
top
If your air curtain incinerator combusts 100 percent yard waste, you must meet only the emission limits in this section.
(a) Within 180 days after your final compliance date, you must meet two limits:
(1) The opacity limit is 10 percent (6-minute average) for air curtain incinerators that can combust at least 35 tons per day of yard waste and no more than 250 tons per day of yard waste.
(2) The opacity limit is 35 percent (6-minute average) during the startup period that is within the first 30 minutes of operation.
(b) Except during malfunctions, the requirements of this subpart apply at all times. Each malfunction must not exceed 3 hours.
§ 62.15380 How must I monitor opacity for air curtain incinerators that burn 100 percent yard waste?
top
(a) Use EPA Reference Method 9 in Appendix A of 40 CFR part 60 to determine compliance with the opacity limit.
(b) Conduct an initial test for opacity as specified in §60.8 of subpart A of 40 CFR part 60.
(c) After the initial test for opacity, conduct annual tests no more than 13 calendar months following the date of your previous test.
§ 62.15385 What are the recordkeeping and reporting requirements for air curtain incinerators that burn 100 percent yard waste?
top
(a) Provide a notice of construction that includes four items:
(1) Your intent to construct the air curtain incinerator.
(2) Your planned initial startup date.
(3) Types of fuels you plan to combust in your air curtain incinerator.
(4) The capacity of your incinerator, including supporting capacity calculations, as specified in §62.15390 (d) and (e).
(b) Keep records of results of all opacity tests onsite in either paper copy or electronic format unless the Administrator approves another format.
(c) Keep all records for each incinerator for at least 5 years.

(e) Submit the results (each 6-minute average) of the opacity tests by February 1 of the year following the year of the opacity emission test.
(f) Submit reports as a paper copy on or before the applicable submittal date. If the Administrator agrees, you may submit reports on electronic media.
(g) If the Administrator agrees, you may change the annual reporting dates (see §60.19(c) in subpart A of 40 CFR part 60).
(h) Keep a copy of all reports onsite for a period of 5 years.
Equations
top
§ 62.15390 What equations must I use?
top
(a) Concentration correction to 7 percent oxygen. Correct any pollutant concentration to 7 percent oxygen using equation 1 of this section:
Where:
C7% = concentration corrected to 7 percent oxygen.
Cunc = uncorrected pollutant concentration.
CO2 = concentration of oxygen (%).
(b) Percent reduction in potential mercury emissions. Calculate the percent reduction in potential mercury emissions (%PHg) using equation 2 of this section:
Where:
%PHg = percent reduction of potential mercury emissions
Ei = mercury emission concentration as measured at the air pollution control device inlet, corrected to 7 percent oxygen, dry basis
Eo = mercury emission concentration as measured at the air pollution control device outlet, corrected to 7 percent oxygen, dry basis
(c) Percent reduction in potential hydrogen chloride emissions. Calculate the percent reduction in potential hydrogen chloride emissions (%PHCl) using equation 3 of this section:
Where:
%PHCl = percent reduction of the potential hydrogen chloride emissions
Ei = hydrogen chloride emission concentration as measured at the air pollution control device inlet, corrected to 7 percent oxygen, dry basis
Eo = hydrogen chloride emission concentration as measured at the air pollution control device outlet, corrected to 7 percent oxygen, dry basis
(d) Capacity of a municipal waste combustion unit. For a municipal waste combustion unit that can operate continuously for 24-hour periods, calculate the capacity of the municipal waste combustion unit based on 24 hours of operation at the maximum charge rate. To determine the maximum charge rate, use one of two methods:
(1) For municipal waste combustion units with a design based on heat input capacity, calculate the maximum charging rate based on this maximum heat input capacity and one of two heating values:
(i) If your municipal waste combustion unit combusts refuse-derived fuel, use a heating value of 12,800 kilojoules per kilogram (5,500 British thermal units per pound).
(ii) If your municipal waste combustion unit combusts municipal solid waste, use a heating value of 10,500 kilojoules per kilogram (4,500 British thermal units per pound).
(2) For municipal waste combustion units with a design not based on heat input capacity, use the maximum designed charging rate.
(e) Capacity of a batch municipal waste combustion unit. Calculate the capacity of a batch municipal waste combustion unit as the maximum design amount of municipal solid waste they can charge per batch multiplied by the maximum number of batches they can process in 24 hours. Calculate this maximum number of batches by dividing 24 by the number of hours needed to process one batch. Retain fractional batches in the calculation. For example, if one batch requires 16 hours, the municipal waste combustion unit can combust 24/16, or 1.5 batches, in 24 hours.
(f) Quarterly carbon usage. If you use activated carbon to comply with the dioxins/furans or mercury limits, calculate the required quarterly usage of carbon using equation 4 or 5 of thissection for plant basis or unit basis: (continued)
