If a storage vessel is removed from an oil and natural gas source and, within 30 days, is either returned to the source or replaced by another storage vessel at the source to serve the same or similar function, then the entire period since the original storage vessel was first located at the source, including the days when the storage vessel was removed, must be added to the count of the number of consecutive days.(6) For each enclosed combustor or flare at an oil and natural gas source required under §§ 49.4173 through 49.4177 : (i) Manufacturer-written, site-specific designs, operating instructions, operating procedures and maintenance schedules, including those of any operation monitoring systems;(ii) Date of installation;(iii) Records of required monitoring of operations in § 49.4182(d)(1) ;(iv) Records of any instances in which the pilot flame is not present or the monitoring equipment is not functioning in the enclosed combustor or flare, the date and times of the occurrence, the corrective actions taken, and any preventative measures adopted to prevent recurrence of the occurrence; and(v) Records of any visible emissions tests conducted according to § 49.4182(d)(3) , including any time periods in which visible smoke emissions are observed emanating from the enclosed combustor or flare.(7) For each closed-vent system: (i) The date of installation; and(ii) Records of any instances in which any closed-vent system or control device was bypassed or down, the reason for each incident, its duration, and the corrective actions taken, and any preventative measures adopted to avoid such bypasses or downtimes.(8) Documentation of all storage vessel and closed-vent system inspections required in § 49.4182(c) .

All inspection records must include the following information: (i) The date of the inspection;(ii) The identification of any component that was determined to be leaking;(iii) The identification of any component designated difficult-to-monitor or unsafe-to-monitor that was not inspected, and the reason it was not inspected;(iv) The date of the first attempt to repair the leaking component;(v) The identification of any leaking component with a delayed repair and the reason for the delayed repair: (A) For unavailable parts: (1) The date of ordering a replacement component; and(2) The date the replacement component was received; and(B) For a shutdown: (1) The reason the repair is technically infeasible;(2) The date of the shutdown;(3) The date of subsequent startup after a shutdown; and(4) Emission estimates of the shutdown and the repair if the delay is longer than 6 months;(vi) The date and description of any corrective action taken, including the date the component was verified to no longer be leaking;(vii) The identification of each component exempt under § 49.4178(d)(2) , including the type of component and a description of the qualifying exemption; and(viii) The inspector's name or identification number.(11) For each well site complying with either § 49.4178(b)(2) or § 49.4178(c)(2) , you must maintain records of the rolling 12-month average daily production no later than 12 months before complying with § 49.4178(b)(2) or § 49.4178(c)(2) .(12) For each electronically controlled automatic ignition system required under § 49.4181 , records demonstrating the date of installation and manufacturer specifications; and(13) For each retrofitted pneumatic controller, the records required in 40 CFR 60.5420(c)(4)(i) .(b) Each owner or operator must keep all records required by this section onsite at the source or at the location that has day-to-day operational control over the source and must make the records available to the EPA upon request.(c) Each owner or operator must retain all records required by this section for a period of at least 5 years from the date the record was created.
