(a) As required by Sec. 63.10(b)(1), you must maintain files of all information (including all reports and notifications) for at least 5 years following the date of each occurrence, measurement, maintenance, corrective action, report, or record. At a minimum, the most recent 2 years of data shall be retained on site. The remaining 3 years of data may be retained off site. Such files may be maintained on microfilm, on a computer, on computer floppy disks, on magnetic tape disks, or on microfiche.
(b) In addition to the records required by 40 CFR 63.10, you must keep records of the information specified in paragraphs (b)(1) through (13) of this section.
(1) You must keep records of your written materials specifications according to Sec. 63.10885(a) and records that demonstrate compliance with the requirements for restricted metallic scrap in Sec. 63.10885(a)(1) and/or for the use of general scrap in Sec. 63.10885(a)(2) and for mercury in Sec. 63.10885(b)(1) through (3), as applicable. You must keep records documenting compliance with Sec. 63.10885(b)(4) for scrap that does not contain motor vehicle scrap.
(2) If you are subject to the requirements for a site-specific plan for mercury under Sec. 63.10885(b)(1), you must:
(i) Maintain records of the number of mercury switches removed or the weight of mercury recovered from the switches and properly managed, the estimated number of vehicles processed, and an estimate of the percent of mercury switches recovered; and
(ii) Submit semiannual reports of the number of mercury switches removed or the weight of mercury recovered from the switches and properly managed, the estimated number of vehicles processed, an estimate of the percent of mercury switches recovered, and a certification that the recovered mercury switches were recycled at RCRA-permitted facilities. The semiannual reports must include a certification that you have conducted periodic inspections or taken other means of corroboration as required under Sec. 63.10885(b)(1)(ii)(C). You must identify which option in Sec. 63.10885(b) applies to each scrap provider, contract, or shipment. You may include this information in the semiannual compliance reports required under paragraph (c) of this section.
(3) If you are subject to the option for approved mercury programs under Sec. 63.10885(b)(2), you must maintain records identifying each scrap provider and documenting the scrap provider's participation in an approved mercury switch removal program. If your scrap provider is a broker, you must maintain records identifying each of the broker's scrap suppliers and documenting the scrap supplier's participation in an approved mercury switch removal program.
(4) You must keep records to document use of any binder chemical formulation that does not contain methanol as a specific ingredient of the catalyst formulation for each furfuryl alcohol warm box mold or core making line as required by Sec. 63.10886. These records must be the Material Safety Data Sheet (provided that it contains appropriate information), a certified product data sheet, or a manufacturer's hazardous air pollutant data sheet.
(5) You must keep records of the annual quantity and composition of each HAP-containing chemical binder or coating material used to make molds and cores. These records must be copies of purchasing records, Material Safety Data Sheets, or other documentation that provide information on the binder or coating materials used.
(6) You must keep records of monthly metal melt production for each calendar year.
(7) You must keep a copy of the operation and maintenance plan as required by Sec. 63.10896(a) and records that demonstrate compliance with plan requirements.
(8) If you use emissions averaging, you must keep records of the monthly metal melting rate for each furnace at your iron and steel foundry, and records of the calculated pounds of PM or total metal HAP per ton of metal melted for the group of all metal melting furnaces required by Sec. 63.10897(h).
(9) If applicable, you must keep records for bag leak detection systems as follows:
(i) Records of the bag leak detection system output;
(ii) Records of bag leak detection system adjustments, including the date and time of the adjustment, the initial bag leak detection system settings, and the final bag leak detection system settings; and
(iii) The date and time of all bag leak detection system alarms, and for each valid alarm, the time you initiated corrective action, the corrective action taken, and the date on which corrective action was completed.
(10) You must keep records of capture system inspections and repairs as required by Sec. 63.10897(e).
(11) You must keep records demonstrating conformance with your specifications for the operation of CPMS as required by Sec. 63.10897(f).
(12) You must keep records of corrective action(s) for exceedances and excursions as required by Sec. 63.10897(g).
(13) You must record the results of each inspection and maintenance required by Sec. 63.10897(a) for PM control devices in a logbook (written or electronic format). You must keep the logbook onsite and make the logbook available to the Administrator upon request. You must keep records of the information specified in paragraphs (b)(13)(i) through (iii) of this section.
(i) The date and time of each recorded action for a fabric filter, the results of each inspection, and the results of any maintenance performed on the bag filters.
(ii) The date and time of each recorded action for a wet or dry electrostatic precipitator (including ductwork), the results of each inspection, and the results of any maintenance performed for the electrostatic precipitator.
(iii) The date and time of each recorded action for a wet scrubber (including ductwork), the results of each inspection, and the results of any maintenance performed on the wet scrubber.
(c) You must submit semiannual compliance reports to the Administrator according to the requirements in Sec. 63.10(e). The reports must include, at a minimum, the following information as applicable:
(1) Summary information on the number, duration, and cause (including unknown cause, if applicable) of excursions or exceedances, as applicable, and the corrective action taken;
(2) Summary information on the number, duration, and cause (including unknown cause, if applicable) for monitor downtime incidents (other than downtime associated with zero and span or other calibration checks, if applicable); and
(3) Summary information on any deviation from the pollution prevention management practices in Secs. 63.10885 and 63.10886 and the operation and maintenance requirements Sec. 63.10896 and the corrective action taken.
(d) You must submit written notification to the Administrator of the initial classification of your new or existing affected source as a large iron and steel facility as required in Sec. 63.10880(f) and (g), as applicable, and for any subsequent reclassification as required in Sec. 63.10881(d) or (e), as applicable.
