Continuous Compliance Requirements

return arrow Back to Top

§63.5555   How do I demonstrate continuous compliance with the emission limits, operating limits, and work practice standards?

(a) You must demonstrate continuous compliance with each emission limit, operating limit, and work practice standard in Tables 1 and 2 to this subpart that applies to you according to methods specified in Tables 5 and 6 to this subpart.

(b) You must report each instance in which you were not in continuous compliance (as specified in Tables 5 and 6 to this subpart) with each emission limit, each operating limit, and each work practice standard that apply to you. This includes periods of startup, shutdown, and malfunction. These instances are deviations from the emission limits, operating limits, and work practice standards in this subpart. These deviations must be reported according to the requirements in §63.5580.

(c) [Reserved]

(d) For each affected source that commenced construction or reconstruction before September 9, 2019, on or before December 29, 2020, deviations that occur during a period of startup, shutdown, or malfunction are not violations if you demonstrate to the Administrator's satisfaction that you were operating in accordance with §63.5515(b). The Administrator will determine whether deviations that occur on or before December 29, 2020, and during a period you identify as a startup, shutdown, or malfunction are violations, according to the provisions in §63.5515(b). This section no longer applies after December 30, 2020. For new sources that commence construction or reconstruction after September 9, 2019, this section does not apply.

[67 FR 40055, June 11, 2002, as amended at 71 FR 20466, Apr. 20, 2006; 85 FR 39995, July 2, 2020]

§63.5560   How do I monitor and collect data to demonstrate continuous compliance?

(a) You must monitor and collect data according to this section.

(b) Except for monitor malfunctions, associated repairs, and required quality assurance or control activities (including, as applicable, calibration checks and required zero and span adjustments), you must monitor continuously (or collect data at all required intervals) at all times that the affected source is operating, including periods of startup, shutdown, and malfunction.

(c) You may not use data recorded during monitoring malfunctions, associated repairs, required quality assurance or control activities, and periods of no flow for all or a portion of an affected source in data averages and calculations used to report emission or operating levels, nor may such data be used in fulfilling a minimum data availability requirement, if applicable. You must use all the data collected during all other periods in assessing the operation of the control device and associated control system.

(d) All terms in this subpart that define a period of time for completing required tasks (e.g., weekly, monthly, quarterly, or annually) refer to the standard calendar periods.

(1) You may change time periods specified in this subpart for completing required tasks by mutual agreement with the Administrator, as specified in subpart A of this part. For example, a period could begin on the compliance date or another date, rather than on the first day of the standard calendar period. For each time period that is changed by agreement, the revised period must remain in effect until it is changed. A new request is not necessary for each recurring period.

(2) Where the period specified for compliance is a standard calendar period, if the initial compliance date occurs after the beginning of the period, then you must comply according to the schedule specified in paragraph (d)(2)(i) or (ii) of this section, as appropriate.

(i) You must comply before the end of the standard calendar period within which the compliance deadline occurs, if there remain at least 3 days for tasks that must be performed weekly, at least 2 weeks for tasks that must be performed monthly, at least 1 month for tasks that must be performed quarterly, or at least 3 months for tasks that must be performed annually; or

(ii) In all instances where a provision of this subpart requires completing a task during each of multiple successive periods, you may perform the required task at any time during the specified period, provided that the task is conducted at a reasonable interval after completion of the task during the previous period.
