| (a) The following recordkeeping requirements apply
in the Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth, El Paso,
and Houston-Galveston-Brazoria areas, as defined in §115.10 of
this title (relating to Definitions).
(1) The owner or operator of storage tank claiming
an exemption in §115.111 of this title (relating to Exemptions)
shall maintain records sufficient to demonstrate continuous compliance
with the applicable exemption criteria. Where applicable, true vapor
pressure, volatile organic compounds (VOC) content type, or a combination
of the two must be recorded initially and at every change of service
or when the storage tank is emptied and refilled.
(2) The owner or operator of an external floating roof
storage tank that is exempt from the requirement for a secondary seal
in accordance with §115.111(a)(1), (6), and (7) of this title
and is used to store VOC with a true vapor pressure greater than 1.0
pounds per square inch absolute (psia) shall maintain records of the
type of VOC stored and the average monthly true vapor pressure of
the stored liquid.
(3) The owner or operator shall maintain records of
the results of inspections required by §115.114(a) of this title
(relating to Inspection and Repair Requirements). For secondary seal
gaps that are required to be physically measured during inspection,
these records must include a calculation of emissions for all secondary
seal gaps that exceed 1/8 inch where the accumulated area of such
gaps is greater than 1.0 square inch per foot of tank diameter. These
calculated emissions inventory reportable emissions must be reported
in the annual emissions inventory submittal required by §101.10
of this title (relating to Emissions Inventory Requirements). The
emissions must be calculated using the following equation.

(4) The owner or operator shall maintain records of
any operational parameter monitoring required in §115.115(a)
of this title (relating to Monitoring Requirements). Such records
must be sufficient to demonstrate proper functioning of those devices
to design specifications and must include, but are not limited to,
the following.
(A) For a direct-flame incinerator, the owner or operator
shall continuously record the exhaust gas temperature immediately
downstream of the device.
(B) For a condensation system, the owner or operator
shall continuously record the outlet gas temperature to ensure the
temperature is below the manufacturer's recommended operating temperature
for controlling the VOC vapors routed to the device.
(C) For a carbon adsorption system or carbon adsorber,
the owner or operator shall:
(i) continuously record the exhaust gas VOC concentration
of any carbon adsorption system monitored according to §115.115(a)(3)(A)
of this title; or
(ii) record the date and time of each switch between
carbon containers and the method of determining the carbon replacement
interval if the carbon adsorption system or carbon adsorber is switched
according to §115.115(a)(3)(B) of this title.
(D) For a catalytic incinerator, the owner or operator
shall continuously record the inlet and outlet gas temperature.
(E) For a vapor recovery unit, the owner or operator
shall maintain records of the continuous operational parameter monitoring
required in §115.115(a)(5) of this title.
(F) For any other control device not listed in this
paragraph, the owner or operator shall maintain records of the continuous
operational parameter monitoring required in §115.115(a)(6) of
this title sufficient to demonstrate proper functioning of the control
device to design specifications.
(5) The owner or operator shall maintain the results
of any testing conducted in accordance with §115.116 of this
title (relating to Testing Requirements) or §115.117 of this
title (relating to Approved Test Methods) at an affected site. Results
may be maintained at an off-site location if made available for review
within 24 hours.
(6) In the Houston-Galveston-Brazoria and Dallas-Fort
Worth areas, and in the Bexar County area beginning January 1, 2025,
the owner or operator shall maintain the following additional records.
(A) The owner or operator of a fixed roof storage tank
that is not required in §115.112(d)(1) or (e)(1) of this title
(relating to Control Requirements) to be equipped with an external
floating roof, internal floating roof, or vapor control system shall
maintain records of the type of VOC stored, the starting and ending
dates when the material is stored, and the true vapor pressure at
the average monthly storage temperature of the stored liquid. This
requirement does not apply to a storage tank with storage capacity
of 25,000 gallons or less storing VOC other than crude oil or condensate,
or to a storage tank with storage capacity of 40,000 gallons or less
storing crude oil or condensate.
(B) The owner or operator of any storage tank that
stores crude oil or condensate prior to custody transfer or at a pipeline
breakout station and is not equipped with a vapor control system shall
maintain records of the estimated uncontrolled emissions from the
storage tank on a rolling 12-month basis. The records must be made
available for review within 72 hours upon request by authorized representatives
of the executive director, the United States Environmental Protection
Agency, or any local air pollution control agency with jurisdiction.
(C) The owner or operator of an external floating roof
or internal floating roof storage tank meeting the extended compliance
date in §115.119(a)(1)(A) or (b)(1)(A) of this title (relating
to Compliance Schedules) shall maintain records of the date of the
last time the storage tank was emptied and degassed.
(D) The owner or operator of any storage tank that
stores crude oil or condensate prior to custody transfer or at a pipeline
breakout station is required by §115.112(e) of this title to
control flash emissions shall maintain records of the manufacturer
or industry standard instructions used to maintain the storage tanks
and tank closure devices in use.
(E) The owner or operator of any storage tank that
stores crude oil or condensate prior to custody transfer or at a pipeline
breakout station shall maintain records of the results of each inspection
and repair required in §115.112(e)(7) or §115.114(a)(5)
of this title, including the following items:
(i) the date of the inspection;
(ii) the status of the device during inspection;
(iii) the amount of time a closure device was open
since the last inspection for reasons not allowed in §115.112(e)(7)(A)
