(1) Contents. Except as specified in paragraphs (e)(4) through (8) of this section, Periodic Reports shall include all information specified in this subpart and subparts referenced by this subpart. (2) Due date. The Periodic Report shall be submitted no later than 60 days after the end of each 6-month period. The first report shall cover the 6-month period after the Notification of Compliance Status report is due. The first report shall be submitted no later than the last day of the month that includes the date 8 months (6 months and 60 days) after the Notification of Compliance Status report is due. (3) Overlap with title V reports. Information required by this subpart, which is submitted with a title V periodic report, need not also be included in a subsequent Periodic Report required by this subpart or subpart referenced by this subpart. The title V report shall be referenced in the Periodic Report required by this subpart. (4) Ethylene production flare reports. For each flare subject to the requirements in 63.1103(e)(4), the Periodic Report shall include the items specified in paragraphs (e)(4)(i) through (vi) of this section in lieu of the information required in 63.999(c)(3) of subpart SS. (i) Records as specified in 63.1109(e)(1) for each 15-minute block during which there was at least one minute when regulated material is routed to a flare and no pilot flame or flare flame is present. Include the start and stop time and date of each 15-minute block. (ii) Visible emission records as specified in 63.1109(e)(2)(iv) for each period of 2 consecutive hours during which visible emissions exceeded a total of 5 minutes. (iii) The periods specified in 63.1109(e)(6). Indicate the date and start time for the period, and the net heating value operating parameter(s) determined following the methods in 63.670(k) through (n) of subpart CC as applicable. (iv) For flaring events meeting the criteria in 63.670(o)(3) of subpart CC and 63.1103(e)(4)(iv): (A) Flare identification name or number and the start and stop time and date of the flaring event. (B) The length of time (in minutes) that emissions were visible from the flare during the event. (C) Results of the root cause and corrective actions analysis completed during the reporting period, including the corrective actions implemented during the reporting period and, if applicable, the implementation schedule for planned corrective actions to be implemented subsequent to the reporting period. (v) For pressure-assisted multi-point flares, the periods of time when the pressure monitor(s) on the main flare header show the burners operating outside the range of the manufacturer's specifications. (vi) For pressure-assisted multi-point flares, the periods of time when the staging valve position indicator monitoring system indicates a stage should not be in operation and is or when a stage should be in operation and is not. (5) Ethylene production maintenance vent reports. For maintenance vents subject to the requirements 63.1103(e)(5), Periodic Reports must include the information specified in paragraphs (e)(5)(i) through (iv) of this section for any release exceeding the applicable limits in 63.1103(e)(5)(i). For the purposes of this reporting requirement, owners or operators complying with 63.1103(e)(5)(i)(D) must report each venting event conducted under those provisions and include an explanation for each event as to why utilization of this alternative was required. (i) Identification of the maintenance vent and the equipment served by the maintenance vent. (ii) The date and time the maintenance vent was opened to the atmosphere. (iii) The LEL, vessel pressure, or mass of VOC in the equipment, as applicable, at the start of atmospheric venting. If the 5 psig vessel pressure option in 63.1103(e)(5)(i)(B) was used and active purging was initiated while the concentration of the vapor was 10 percent or greater of its LEL, also include the concentration of the vapors at the time active purging was initiated. (iv) An estimate of the mass of organic HAP released during the entire atmospheric venting event. (6) Bypass line reports. For bypass lines subject to the requirements in 63.1103(e)(6), Periodic Reports must include the date, time, duration, estimate of the volume of gas, the concentration of organic HAP in the gas and the resulting mass emissions of organic HAP that bypass a control device. For periods when the flow indicator is not operating, report the date, time, and duration. (7) Decoking operation reports. For decoking operations of an ethylene cracking furnace subject to the requirements in 63.1103(e)(7) and (8), Periodic Reports must include the information specified in paragraphs (e)(7)(i) through (iii) of this section. (i) For each control measure selected to minimize coke combustion emissions as specified in 63.1103(e)(7)(ii) through (v), report instances where the control measures were not followed. (ii) Report instances where an isolation valve inspection was not conducted according to the procedures specified in 63.1103(e)(8). (iii) For instances where repair was delayed beyond 1 calendar day as specified in 63.1103(e)(7)(i), report the information specified in 63.1109(h)(1). (8) Ethylene production pressure relief devices reports. For pressure relief devices subject to the requirements of 63.1107(h), Periodic Reports must include the information specified in paragraphs (e)(8)(i) through (iii) of this section. (i) For pressure relief devices in organic HAP gas or vapor service, pursuant to 63.1107(h)(1), report any instrument reading of 500 ppm or greater. (ii) For pressure relief devices in organic HAP gas or vapor service subject to 63.1107(h)(2), report confirmation that any monitoring required to be done during the reporting period to show compliance was conducted. (iii) For pressure relief devices in organic HAP service subject to 63.1107(h)(3), report each pressure release to the atmosphere, including pressure relief device identification name or number; start date and start time and duration (in hours) of the pressure release; an estimate (in pounds) of the mass quantity of each organic HAP released; the results of any root cause analysis and corrective action analysis completed during the reporting period, including the corrective actions implemented during the reporting period; and, if applicable, the implementation schedule for planned corrective actions to be implemented subsequent to the reporting period.
