Current through Reg. 49, No. 28; July 12, 2024
(a) The owner or operator of any cooling
					 tower heat exchange system subject to §
											115.761
					 of this title (relating to Site-wide Cap) shall comply with the following
					 recordkeeping requirements:
(1) establish and
					 maintain a process diagram of the cooling tower heat exchange system, including
					 the locations at which the system will be monitored and sampled such that the
					 cooling water is not exposed to the atmosphere prior to sampling;
(2) maintain records of all monitoring,
					 testing, and calibrations performed in accordance with the provisions of §
												115.764
					 of this title (relating to Monitoring and Testing Requirements);
(3) maintain hourly records that document the
					 emission rate in pounds per hour (lb/hr) for each hour for speciated
					 highly-reactive volatile organic compounds (HRVOC) and total HRVOC from the
					 cooling water for each cooling tower heat exchange system as required by
					 §115.764(a), (b), (d), or (h) of this title. The flow rate of the cooling
					 water in conjunction with the most recently monitored concentration of the
					 speciated HRVOC or total HRVOC in the cooling tower water, shall be used to
					 calculate the respective emission rate in lb/hr. If the concentration results
					 of the speciated HRVOC or total HRVOC analyses are below the minimum detection
					 limit (i.e., non-detected), then half the detection limit(s) must be used to
					 calculate HRVOC emissions;
(4)
					 maintain hourly records of the total strippable VOC concentration in the
					 cooling water for cooling tower heat exchanger systems monitored in accordance
					 with §
												115.764(a)(2)
					 of this title, and maintain records of each test for total strippable VOC
					 concentration performed in accordance with §115.764(b)(2), (d), or (h) of
					 this title. If the concentration results of the total strippable VOC testing or
					 monitoring are below the minimum detection limit, then one-half the detection
					 limit must be used to calculate average total strippable VOC
					 concentration;
(5) maintain hourly
					 records of the cooling water flow rate;
(6) maintain records on a weekly basis that
					 detail all corrective actions made to the continuous monitoring systems during
					 monitor downtimes, and any delay in corrective action taken by documenting the
					 dates, reasons, and durations of such occurrences; and
(7) for cooling tower heat exchange systems
					 that comply with §
												115.764(h)
					 of this title, maintain records including, but not limited to:
(A) the monitoring plan required by §
													115.764(h)(6)
					 of this title;
(B) hourly records
					 of the inventory level of the finite volume system from the continuous
					 monitoring system required by §
													115.764(h)(6)
					 of this title; and
(C) the date,
					 time, purpose, and amount of all transfers of HRVOC into and out of the finite
					 volume system;
