(2) Date, time, duration, and cause of the deviations.
(3) If the facility determines by its monthly compliance demonstration, in accordance with § 63.3370, as applicable, that the source failed to meet an applicable emission limit of this subpart, you must record the following for the corresponding affected equipment:
(i) Record an estimate of the quantity of HAP (or VOC if used a surrogate in accordance with § 63.3360(d)) emitted in excess of the emission limit for the month, and a description of the method used to estimate the emissions.
(ii) Record actions taken to minimize emissions in accordance with § 63.3340(a), and any corrective actions taken to return the affected unit to its normal or usual manner of operation.
(d) Records of results from the annual catalyst activity test, if applicable.
(e) Any records required to be maintained by this part that are submitted electronically via EPA's CEDRI may be maintained in electronic format.
