Section 61.246 - Recordkeeping requirements(a)(1) Each owner or operator subject to the provisions of this subpart shall comply with the recordkeeping requirements of this section.(2) An owner or operator of more than one process unit subject to the provisions of this subpart may comply with the recordkeeping requirements for these process units in one recordkeeping system if the system

weatherproof and readily visible identification, marked with the equipment identification number, shall be attached to the leaking equipment.(2) The identification on a valve may be removed after it has been monitored for 2 successive months as specified in § 61.242-7(c) and no leak has been detected during those 2 months.(3) The identification on equipment, except on a valve, may be removed after it has been repaired.(c) When each leak is detected as specified in §§ 61.242-2 , 61.242-3 . 61.242-7, 61.242-8, and 61.135, the following information shall be recorded in a log and shall be kept for 2 years in a readily accessible location: (1) The instrument and operator identification numbers and the equipment identification number.(2) The date the leak was detected and the dates of each attempt to repair the leak.(3) Repair methods applied in each attempt to repair the leak.(4) "Above 10,000" if the maximum instrument reading measured by the methods specified in § 61.245(a) after each repair attempt is equal to or greater than 10,000 ppm.(5) "Repair delayed" and the reason for the delay if a leak is not repaired within 15 calendar days after discovery of the leak.(6) The signature of the owner or operator (or designate) whose decision it was that repair could not be effected without a process shutdown.(7) The expected date of successful repair of the leak if a leak is not repaired within 15 calendar days.(8) Dates of process unit shutdowns that occur while the equipment is unrepaired.(9) The date of successful repair of the leak.(d) The following information pertaining to the design requirements for closed-vent systems and control devices described in § 61.242-11 shall be recorded and kept in a readily accessible location:(1) Detailed schematics, design specifications, and piping and instrumentation diagrams.(2) The dates and descriptions of any changes in the design specifications.(3) A description of the parameter or parameters monitored, as required in § 61.242-11(e) , to ensure that control devices are operated and maintained in conformance with their design and an explanation of why that parameter (or parameters) was selected for the monitoring.(4) Periods when the closed-vent systems and control devices required in §§ 61.242-2 , 61.242-3 , 61.242-4 , 61.242-5 and 61.242-9 are not operated as designed, including periods when a flare pilot light does not have a flame.(5) Dates of startups and shutdowns of the closed-vent systems and control devices required in §§ 61.242-2 , 61.242-3 , 61.242-4 , 61.242-5 and 61.242-9 .(e) The following information pertaining to all equipment to which a standard applies shall be recorded in a log that is kept in a readily accessible location:(1) A list of identification numbers for equipment (except welded fittings) subject to the requirements of this subpart.(2)(i) A list of identification numbers for equipment that the owner or operator elects to designate for no detectable emissions as indicated by an instrument reading of less than 500 ppm above background.(ii) The designation of this equipment for no detectable emissions shall be signed by the owner or operator.(3) A list of equipment identification numbers for pressure relief devices required to comply with § 61.242-4(a) .(4)(i) The dates of each compliance test required in §§ 61.242-2(e) , 61.242-3(i) , 61.242-4 , 61.242-7(f) , and 61.135(g) .(ii) The background level measured during each compliance test.(iii) The maximum instrument reading measured at the equipment during each compliance test.(5) A list of identification numbers for equipment in vacuum service.(f) The following information pertaining to all valves subject to the requirements of § 61.242-7(g) and (h) and to all pumps subject to the requirements of § 61.242-2(g) shall be recorded in a log that is kept in a readily accessible location: (1) A list of identification numbers for valves and pumps that are designated as unsafe to monitor, an explanation for each valve or pump stating why the valve or pump is unsafe to monitor, and the plan for monitoring each valve or pump.(2) A list of identification numbers for valves that are designated as difficult to monitor, an explanation for each valve stating why the valve is difficult to monitor, and the planned schedule for monitoring each valve.(g) The following information shall be recorded for valves complying with § 61.243-2 : (1) A schedule of monitoring.(2) The percent of valves found leaking during each monitoring period.(h) The following information shall be recorded in a log that is kept in a readily accessible location: (1) Design criterion required in §§ 61.242-2(d)(5) , 61.242-3(e)(2) , and 61.135(e)(4) and an explanation of the design criterion; and(2) Any changes to this criterion and the reasons for the changes.(i) The following information shall be recorded in a log that is kept in a readily accessible location for use in determining exemptions as provided in the applicability section of this subpart and other specific subparts:(1) An analysis demonstrating the design capacity of the process unit, and(2) An analysis demonstrating that equipment is not in VHAP service.(j) Information and data used to demonstrate that a piece of equipment is not in VHAP service shall be recorded in a log that is kept in a readily accessible location.49 FR 23513, June 6, 1984, as amended at 49 FR 38946, Oct. 2, 1984; 54 FR 38077, Sept. 14, 1989; 65 FR 78283 , Dec. 14, 2000
