(a) Summary of reporting requirements. You must submit the following reports to the Administrator:
(1) If a source fails to meet an applicable standard, report such events in the excess emissions and continuous monitoring system performance report and summary report. For each failure to meet an applicable standard, report the start date, start time, end date, end time, and cause of each failure. For each failure the report must also identify the affected sources and equipment, the applicable standard that was not met, an estimate of the quantity in pounds of each regulated pollutant emitted over any emission limit, and a description of the method used to estimate the emissions.
(2) Beginning August 3, 2026, submit the compliance progress report required under § 63.10(d)(4) and the periodic startup, shutdown, and malfunction reports required under § 63.10(d)(5)(i) as a portable document format (PDF) uploads according to § 63.1211(g).
(3) Beginning June 3, 2027, or once the report template for this subpart has been available on the CEDRI website for one year, whichever date is later, submit the excess emissions and continuous monitoring system performance report and summary report required by § 63.10(e)(3), including the information required by paragraph (a)(1) of this section, according to § 63.1211(g). When the report is submitted via CEDRI, the certifier's electronic signature during the submission process replaces the requirements in § 63.10(e)(3)(v), (e)(3)(vi)(L), and (e)(3)(vi)(M) of subpart A of this part to submit the date of the report and the name, title, and signature of the responsible official who is certifying the accuracy of the report.
(b) Summary of recordkeeping requirements. You must retain the following in the operating record:
(c) Documentation of compliance.
(1) By the compliance date, you must develop and include in the operating record a Documentation of Compliance. You are not subject to this requirement, however, if you submit a Notification of Compliance under § 63.1207(j) prior to the compliance date. Upon inclusion of the Documentation of Compliance in the operating record, hazardous waste burning incinerators, cement kilns, and lightweight aggregate kilns regulated under the interim standards of §§ 63.1203, 63.1204, and 63.1205 are no longer subject to compliance with the previously applicable Notification of Compliance.
(2) The Documentation of Compliance must identify the applicable emission standards under this subpart and the limits on the operating parameters under § 63.1209 that will ensure compliance with those emission standards.
(3) You must include a signed and dated certification in the Documentation of Compliance that:
(i) Required CEMs and CMS are installed, calibrated, and continuously operating in compliance with the requirements of this subpart; and
(ii) Based on an engineering evaluation prepared under your direction or supervision in accordance with a system designed to ensure that qualified personnel properly gathered and evaluated the information and supporting documentation, and considering at a minimum the design, operation, and maintenance characteristics of the combustor and emissions control equipment, the types, quantities, and characteristics of feedstreams, and available emissions data:
(A) You are in compliance with the emission standards of this subpart; and
(B) The limits on the operating parameters under § 63.1209 ensure compliance with the emission standards of this subpart.
(4) You must comply with the emission standards and operating parameter limits specified in the Documentation of Compliance.
(d) Data compression. You may submit a written request to the Administrator for approval to use data compression techniques to record data from CMS, including CEMS, on a frequency less than that required by § 63.1209. You must submit the request for review and approval as part of the comprehensive performance test plan.
(1) You must record a data value at least once each ten minutes.
(2) For each CEMS or operating parameter for which you request to use data compression techniques, you must recommend:
(i) A fluctuation limit that defines the maximum permissible deviation of a new data value from a previously generated value without requiring you to revert to recording each one-minute value.
(A) If you exceed a fluctuation limit, you must record each one-minute value for a period of time not less than ten minutes.
(B) If neither the fluctuation limit nor the data compression limit are exceeded during that period of time, you may reinitiate recording data values on a frequency of at least once each ten minutes; and
(ii) A data compression limit defined as the closest level to an operating parameter limit or emission standard at which reduced data recording is allowed.
(A) Within this level and the operating parameter limit or emission standard, you must record each one-minute average.
(B) The data compression limit should reflect a level at which you are unlikely to exceed the specific operating parameter limit or emission standard, considering its averaging period, with the addition of a new one-minute average.
(e) Other recordkeeping. You must retain the following in the operating record:
(1) The start date, start time, and duration (hours) of each startup, shutdown, or malfunction of process, air pollution control, and monitoring equipment and whether the startup, shutdown, and malfunction plan was followed.
(2) For periods of startup, shutdown, and malfunction when the startup, shutdown, and malfunction plan was not followed, record and retain a list of the affected sources or equipment; actions taken to minimize emissions in accordance with §§ 63.6(e)(1)(i) and 63.8(c)(1)(i); any corrective actions taken to return the affected unit to its normal or usual manner of operation; whether the failure occurred during a period of startup, shutdown or malfunction; an estimate of the quantity of each regulated pollutant emitted; and a description of the method used to estimate the emissions.
(f) Electronic Reporting. Beginning on September 1, 2026, within 90 days after the date of completing each performance test or continuous emissions monitoring system (CEMS) performance evaluation (as defined in § 63.2) that includes a relative accuracy test audit (RATA), required by this subpart, you must submit the results of the performance test following the procedure specified in § 63.9(k). Submit the data in a file format generated using the EPA's Electronic Reporting Tool (ERT). Alternatively, you may submit an electronic file consistent with the extensible markup language (XML) schema listed on the EPA's ERT website (https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) accompanied by the other information required by § 63.7(g)(2) in PDF format.
(g) Reporting Confidential Business Information. Where directed to this paragraph (g), the owner or operator must submit all subsequent reports or notifications in the format specified in the referring paragraph to the EPA following the procedure specified in § 63.9(k), except any medium submitted as Confidential Business Information must be sent to the attention of the Hazardous Waste Combustion Sector Lead.
