The following recordkeeping requirements apply to the owner or operator of each surface coating process in the Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth, El Paso, and Houston-Galveston-Brazoria areas, and in Gregg, Nueces, and Victoria Counties. Records of non-exempt solvent washings are not required to be kept if the non-exempt solvent is directed into containers that prevent evaporation into the atmosphere.
  (1) The owner or operator shall satisfy the following recordkeeping requirements.
    (A) A material data sheet must be maintained that documents the volatile organic compound (VOC) content, composition, solids content, solvent density, and other relevant information regarding each coating and solvent available for use in the affected surface coating processes sufficient to determine continuous compliance with applicable control limits.
    (B) Records must be maintained of the quantity and type of each coating and solvent consumed during the specified averaging period if any of the coatings, as delivered to the coating application system, exceed the applicable control limits. Such records must be sufficient to calculate the applicable weighted average of VOC for all coatings.
      (i) As an alternative to the recordkeeping requirements of this subparagraph, the owner or operator of any vehicle refinishing (body shop) operation subject to §115.421(11) of this title may substitute the recordkeeping requirements specified in §106.436 of this title (relating to Auto Body Refinishing Facility (Previously Standard Exemption 124)) provided that all coatings and solvents meet the emission limits of §115.421(11) of this title. If the owner or operator of a vehicle refinishing (body shop) operation that uses any coating or solvent which exceeds the limits of §115.421(11) of this title, then the owner or operator shall maintain daily records of the quantity and type of each coating and solvent consumed in sufficient detail to calculate the daily weighted average of VOC for all coatings and solvents.
      (ii) As an alternative to the recordkeeping requirements of this subparagraph, the owner or operator of any wood parts and products coating operation subject to §115.421(14) of this title may substitute the recordkeeping requirements specified in §106.231 of this title (relating to Manufacturing, Refinishing, and Restoring Wood Products) provided that all coatings and solvents meet the emission limits of §115.421(14) of this title. If the owner or operator of a wood parts and products coating operation uses any coating or solvent which exceeds the limits of §115.421(14) of this title, then the owner or operator shall maintain daily records of the quantity and type of each coating and solvent consumed in sufficient detail to calculate the daily weighted average of VOC for all coatings and solvents.
      (iii) As an alternative to the recordkeeping requirements of this subparagraph, the owner or operator of any surface coating operation that qualifies for exemption under §115.427(3)(C) of this title (relating to Exemptions) shall maintain records of total gallons of coating and solvent used in each month, and total gallons of coating and solvent used in the previous 12 months.
    (C) Records shall be maintained of any testing conducted at an affected facility in accordance with the provisions specified in §115.425 of this title (relating to Testing Requirements).
    (D) Records required by subparagraphs (A) - (C) of this paragraph must be maintained for at least two years and must be made available upon request by representatives of the executive director, the United States Environmental Protection Agency (EPA), or any local air pollution control agency with jurisdiction.
  (2) The owner or operator of any surface coating facility that utilizes a vapor control system approved by the executive director in accordance with §115.423(3) of this title (relating to Alternate Control Requirements) shall:
    (A) install and maintain monitors to accurately measure and record operational parameters of all required control devices, as necessary, to ensure the proper functioning of those devices in accordance with design specifications, including:
      (i) continuous monitoring of the exhaust gas temperature immediately downstream of direct-flame incinerators and/or the gas temperature immediately upstream and downstream of any catalyst bed;
      (ii) the total amount of VOC recovered by carbon adsorption or other solvent recovery systems during a calendar month;
      (iii) continuous monitoring of carbon adsorption bed exhaust; and
      (iv) appropriate operating parameters for vapor control systems other than those specified in clauses (i) - (iii) of this subparagraph;
    (B) maintain records of any testing conducted in accordance with the provisions specified in §115.425(2) of this title; and
    (C) maintain all records at the affected facility for at least two years and make such records available to representatives of the executive director, EPA, or any local air pollution control agency with jurisdiction, upon request.
  (3) The owner or operator shall maintain, on file, the capture efficiency protocol submitted under §115.425(4) of this title. The owner or operator shall submit all results of the test methods and capture efficiency protocols to the executive director within 60 days of the actual test date. The owner or operator shall maintain records of the capture efficiency operating parameter values on site for a minimum of one year. If any changes are made to capture or control equipment, the owner or operator is required to notify the executive director in writing within 30 days of these changes and a new capture efficiency and/or control device destruction or removal efficiency test may be required.
  (4) The owner or operator shall maintain records sufficient to document the applicability of the conditions for exemptions referenced in §115.427 of this title.
  (5) The following additional requirements apply to each aerospace vehicle or component coating process subject to §115.421(10) of this title. The owner or operator shall:
    (A) for coatings:
      (i) maintain a current list of coatings in use with category and VOC content as applied; and
      (ii) record coating usage on an annual basis;
    (B) for aqueous and semiaqueous hand-wipe cleaning solvents, maintain a list of materials used with corresponding water contents;
    (C) for vapor pressure compliant hand-wipe cleaning solvents:
      (i) maintain a current list of cleaning solvents in use with their respective vapor pressures or, for blended solvents, VOC composite vapor pressures; and
      (ii) maintain a record cleaning solvent usage on an annual basis; and
    (D) for cleaning solvents with a vapor pressure greater than 45 millimeters of mercury at 20 degrees Celsius used in exempt hand-wipe cleaning operations:
      (i) maintain a list of exempt hand-wipe cleaning processes; and
      (ii) maintain a record cleaning solvent usage on an annual basis.
  (6) Except for specialty coatings, compliance with the recordkeeping requirements of 40 Code of Federal Regulations §63.752, (National Emission Standards for Aerospace Manufacturing and Rework Facilities), is considered to represent compliance with the requirements of this section.
