Instead of conducting the initial performance test in § 60.2927(a), very small municipal waste combustion units and institutional waste incineration units with capacities less than or equal to 10 tons per day may demonstrate initial compliance according to the requirements in paragraphs (a) through (d) of this section.

(a) You must submit the information specified in paragraph (a)(1) of this section and comply with the requirements of paragraph (a)(2) of this section for each very small municipal waste combustion unit or institutional waste incineration unit for which you are using a substitute means of compliance demonstration.

(1) On or before December 29, 2025 or within 60 days of startup, whichever is later, you must submit a written notification to the Administrator via CEDRI, which can be accessed through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov), that you intend to use the substitute means of compliance demonstration. Your submittal must include information on the design and operation of the OSWI unit, including the information in paragraphs (a)(1)(i) through (iv) of this section. Do not use CEDRI to submit information you claim as confidential business information (CBI). If you wish to assert a CBI claim, submit the information listed below following the procedures in paragraph (b)(3) of this section.

(i) Manufacturer, make, and model of the unit.

(ii) Type of unit (e.g., burn barrel, incinerator with secondary chamber, etc.).

(iii) Capacity of the unit.

(iv) The anticipated waste profile, as defined in § 60.2977.

(2) Beginning on December 29, 2025 or upon initial startup, whichever is later, you must collect the data in paragraphs (a)(2)(i) through (vii) of this section. You must continue to collect the data in paragraphs (a)(2)(i) through (vii) of this section until you meet the requirements of paragraph (b) of this section.

(i) Identity and weight of each waste type (e.g., lbs of paper waste, food waste, wood or yard waste) on a weekly total basis for the date range the information is collected.

(ii) Identity and quantities (e.g., flow rate or percentage of operating time) of supplemental fuels burned on a weekly total basis for the date range the information is collected.

(iii) Percentage of total waste burned for each waste type on a weekly average basis for the date range the information is collected.

(iv) Temperature indicative of the combustion chamber and description of where temperature is measured. Record this information on a 3-hour rolling average basis for the date range the information is collected.

(v) Hours operated per day for the date range the information is collected.

(vi) Charge rate each day in tons per day for the date range the information is collected.

(vii) Operating parameter data for any air pollution control devices. For wet scrubbers, include pressure drop across the scrubber or amperage to the scrubber, scrubber liquor inlet flow rate, and scrubber liquor pH at the outlet of the scrubber. For dry scrubbers, include injection rate of each sorbent used. For electrostatic precipitators, include the secondary voltage, secondary amperage, and secondary power. Record this information on a 3-hour rolling average basis for the date range the information is collected.

(b) On or before the latest of March 30, 3027; 60 days after the very small municipal waste combustion unit or institutional waste incineration unit reaches the charge rate at which it will operate; or 180 days after initial startup, you must identify the results of a performance test in the EPA's WebFIRE database that is representative for your very small municipal waste combustion unit or institutional waste incineration unit using the criteria in paragraphs (b)(2)(i) through (viii) of this section and submit the information in paragraphs (b)(1) and (2) of this section. You must submit the information following the procedure in paragraph (b)(3) of this section. The performance test may be any test that meets the requirements in paragraph (c) of this section, regardless of location, that is representative of your OSWI unit.

(1) Identify the representative performance test used to demonstrate initial compliance with each very small municipal waste combustion unit or institutional waste incineration unit by submitting the information in paragraphs (b)(1)(i) through (vi) of this section as provided in the EPA's WebFIRE database for the performance test:

(i) Organization.

(ii) Facility.

(iii) City.

(iv) State.

(v) County.

(vi) Submission date.

(2) Describe how the test is representative for your OSWI unit, based on the following criteria, using the data submitted as specified in paragraph (a)(1) of this section and collected as specified in paragraph (a)(2) of this section:

(i) Unit design, including type of unit and any associated air pollution control devices.

(ii) Charge rate.

(iii) Type of operation (batch, continuous, intermittent).

(iv) Combustion temperature and location of temperature measurement.

(v) Type(s) of waste burned.

(vi) Waste profile, as defined in § 60.2977.

(vii) Type and amount of supplemental fuels.

(viii) Similarity of air pollution control devices and operation of the air pollution control devices, if the performance test was conducted on a unit with an air pollution control device.

(3) You must submit the information required in paragraphs (b)(1) and (2) of this section via CEDRI, which can be accessed through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). The EPA will make all the information submitted through CEDRI available to the public without further notice to you. Do not use CEDRI to submit information you claim as CBI. If you wish to assert a CBI claim, submit the information, including information claimed to be CBI, to the EPA following the procedures in paragraphs (b)(3)(i) and (ii) of this section. Clearly mark the part or all of the information that you claim as CBI. Information not marked as CBI may be authorized for public release without prior notice. Information marked as CBI will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the EPA is required to make emissions data available to the public. Thus, emissions data will not be protected as CBI and will be made publicly available. You must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph.

(i) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address [email protected], and as described above, should include clear CBI markings and be flagged to the attention of the Other Solid Waste Incinerator Units Sector Lead. If assistance is needed with submitting large electronic files that exceed the file size limit for email attachments, and if you do not have your own file sharing service, please email [email protected] to request a file transfer link.

(ii) If you cannot transmit the file electronically, you may send CBI information through the postal service to the following address: U.S. EPA, Attn: OAQPS Document Control Officer and Other Solid Waste Incinerator Units Sector Lead, Mail Drop: C404-02, 109 T.W. Alexander Drive, P.O. Box 12055, RTP, NC 27711. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.

(c) Any performance test used as a representative test in a substitute means of compliance demonstration under paragraph (b) of this section must be conducted following the initial testing requirements of § 60.2922 and demonstrate compliance with the emission limits in table 1b to this subpart. In addition to the results of the performance test and the information required by § 60.8(f)(2), the performance test report must contain the information in paragraphs (c)(1) through (8) of this section.

(1) Unit design, including type of unit and any associated air pollution control devices.

(2) Charge rate during the test.

(3) Type of operation (batch, continuous, intermittent).

(4) Combustion temperature and location of temperature measurement. The temperature must be recorded continuously for each run of the performance test. The performance test report must also identify the lowest 1-hour average combustion chamber operating temperature.

(5) Types of waste burned during the test.

(6) Waste profile, as defined in § 60.2977, established during the test.

(7) Type and amount of supplemental fuels burned during the test and the timeframe that each supplemental fuel was burned during the test.

(8) If the performance test was conducted on a unit with an air pollution control device, the operating parameter data for the control device must be recorded continuously for each run of the performance test. The performance test report must also identify the lowest or highest, as applicable, 1-hour average for the operating parameter.

(i) For wet scrubbers, the performance test report must include data for pressure drop across the scrubber or amperage to the scrubber, scrubber liquor inlet flow rate, and scrubber liquor pH at the outlet of the scrubber.

(ii) For dry scrubbers, the performance test report must include data for the injection rate of each sorbent used.

(iii) For electrostatic precipitators, the performance test report must include data for the secondary voltage, secondary amperage, and secondary power.

(d) If there are no results from a performance test that meet the requirements of paragraph (c) of this section that are representative of your OSWI unit, you must demonstrate initial compliance according to the requirements of § 60.2927(a).
