(a) The recordkeeping provisions of subpart A of this part, that apply and those that do not apply to owners and operators of facilities subject to this subpart are listed in Table 2 of this subpart. (b) Except as specified in paragraphs (c) and (d) of this section, each owner or operator of a facility subject to this subpart shall maintain the records specified in paragraphs (b)(1) through (b)(10) of this section: (1) The owner or operator of an affected source subject to the provisions of this subpart shall maintain files of all information (including all reports and notifications) required by this subpart. The files shall be retained for at least 5 years following the date of each occurrence, measurement, maintenance, corrective action, report or period. (i) All applicable records shall be maintained in such a manner that they can be readily accessed. (ii) The most recent 12 months of records shall be retained on site or shall be accessible from a central location by computer or other means that provides access within 2 hours after a request. (iii) The remaining 4 years of records may be retained offsite. (iv) Records may be maintained in hard copy or computer-readable form including, but not limited to, on paper, microfilm, computer, floppy disk, magnetic tape, or microfiche. (2) Records specified in Sec. 63.10(b)(2); (3) Records specified in Sec. 63.10(c) for each monitoring system operated by the owner or operator in accordance with the requirements of Sec. 63.1283(d). Notwithstanding the previous sentence, monitoring data recorded during periods identified in paragraphs (b)(2)(i) through (b)(2)(iv) of this section shall not be included in any average or percent leak rate computed under this subpart. Records shall be kept of the times and durations of all such periods and any other periods during process or control device operation when monitors are not operating. (i) Monitoring system breakdowns, repairs, calibration checks, and zero (low-level) and high-level adjustments; (ii) Startup, shutdown, and malfunction events. During startup, shutdown and malfunction events, the owner or operator shall maintain records indicating whether or not the startup, shutdown, or malfunction plan, required under Sec. 63.1272(d), was followed. (iii) Periods of non-operation resulting in cessation of the emissions to which the monitoring applies; and (iv) Excursions due to invalid data as defined in Sec. 63.1283(d)(6)(iii). (4) Each owner or operator using a control device to comply with Sec. 63.1274 shall keep the following records up-to-date and readily accessible: (i) Continuous records of the equipment operating parameters specified to be monitored under Sec. 63.1283(d) or specified by the Administrator in accordance with Sec. 63.1283(d)(3)(iii). For flares, the hourly records and records of pilot flame outages specified in Sec. 63.1283(d)(3)(i)(C) shall be maintained in place of continuous records. (ii) Records of the daily average value of each continuously monitored parameter for each operating day determined according to the procedures specified in Sec. 63.1283(d)(4) of this subpart. For flares, records of the times and duration of all periods during [[Page 134]] which all pilot flames are absent shall be kept rather than daily averages. (iii) Hourly records of whether the flow indicator specified under Sec. 63.1281(c)(3)(i)(A) was operating and whether flow was detected at any time during the hour, as well as records of the times and durations of all periods when the vent stream is diverted from the control device or the monitor is not operating. (iv) Where a seal or closure mechanism is used to comply with Sec. 63.1281(c)(3)(i)(B), hourly records of flow are not required. In such cases, the owner or operator shall record that the monthly visual inspection of the seals or closure mechanism has been done, and shall record the duration of all periods when the seal mechanism is broken, the bypass line valve position has changed, or the key for a lock-and- key type lock has been checked out, and records of any car-seal that has broken. (5) Records identifying all parts of the closed-vent system that are designated as unsafe to inspect in accordance with Sec. 63.1283(c)(5), an explanation of why the equipment is unsafe to inspect, and the plan for inspecting the equipment. (6) Records identifying all parts of the closed-vent system that are designated as difficult to inspect in accordance with Sec. 63.1283(c)(6), an explanation of why the equipment is difficult to inspect, and the plan for inspecting the equipment. (7) For each inspection conducted in accordance with Sec. 63.1283(c), during which a leak or defect is detected, a record of the information specified in paragraphs (b)(7)(i) through (b)(7)(viii) of this section. (i) The instrument identification numbers, operator name or initials, and identification of the equipment. (ii) The date the leak or defect was detected and the date of the first attempt to repair the leak or defect. (iii) Maximum instrument reading measured by the method specified in Sec. 63.1283(c)(3) after the leak or defect is successfully repaired or determined to be nonrepairable. (iv) ``Repair delayed'' and the reason for the delay if a leak or defect is not repaired within 15 calendar days after discovery of the leak or defect. (v) The name, initials, or other form of identification of the owner or operator (or designee) whose decision it was that repair could not be effected without a shutdown. (vi) The expected date of successful repair of the leak or defect if a leak or defect is not repaired within 15 calendar days. (vii) Dates of shutdowns that occur while the equipment is unrepaired. (viii) The date of successful repair of the leak or defect. (8) For each inspection conducted in accordance with Sec. 63.1283(c) during which no leaks or defects are detected, a record that the inspection was performed, the date of the inspection, and a statement that no leaks or defects were detected. (9) Records of glycol dehydration unit baseline operations calculated as required under Sec. 63.1281(e)(1). (10) Records required in Sec. 63.1281(e)(3)(i) documenting that the facility continues to operate under the conditions specified in Sec. 63.1281(e)(2). (c) An owner or operator that elects to comply with the benzene emission limit specified in Sec. 63.1275(b)(1)(ii) shall document, to the Administrator's satisfaction, the following items: (1) The method used for achieving compliance and the basis for using this compliance method; and (2) The method used for demonstrating compliance with 0.90 megagrams per year of benzene. (3) Any information necessary to demonstrate compliance as required in the methods specified in paragraphs (c)(1) and (c)(2) of this section. (d) An owner or operator that is exempt from control requirements under Sec. 63.1274(d) shall maintain the records specified in paragraph (d)(1) or (d)(2) of this section, as appropriate, for each glycol dehydration unit that is not controlled according to the requirements of Sec. 63.1274(c). (1) The actual annual average natural gas throughput (in terms of natural gas flowrate to the glycol dehydration unit per day), as determined in accordance with Sec. 63.1282(a)(1); or (2) The actual average benzene emissions (in terms of benzene emissions [[Page 135]] per year), as determined in accordance with Sec. 63.1282(a)(2). (e) Record the following when using a flare to comply with Sec. 63.1281(d): (1) Flare design (i.e., steam-assisted, air-assisted, or non- assisted); (2) All visible emission readings, heat content determinations, flowrate measurements, and exit velocity determinations made during the compliance determination required by Sec. 63.1282(d)(2); and (3) All periods during the compliance determination when the pilot flame is absent.
