Section 115.766 - Recordkeeping and Reporting Requirements(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;(b) The owner or operator of any cooling tower heat exchange system claiming an exemption under § 115.767 of this title (relating to Exemptions) shall comply with the following recordkeeping requirements: (1) maintain records of the heat exchanger pressure differential to document continuous compliance with the exemption criteria of § 115.767(1) of this title; or(2) maintain records of the content of the process side fluid or intervening fluid in each heat exchanger to demonstrate continuous compliance with the exemption criteria of § 115.767(2) and (5) of this title.(c) The owner or operator shall maintain all records necessary to demonstrate continuous compliance and records of periodic measurements for at least five years and make them available for review upon request by authorized representatives of the executive director, United States Environmental Protection Agency, or any local air pollution control agency with jurisdiction.(d) The owner or operator of any cooling tower heat exchange system using the alternate periodic monitoring available under § 115.764(d) of this title shall maintain sufficient records to demonstrate that no individual heat exchanger has 5.0% or greater HRVOC in the process-side fluid.(e) The owner or operator of any cooling tower heat exchange system using manufacturer's pump performance data to determine the maximum potential flow rate, as specified in § 115.764(e)(1) of this title, shall maintain the following records for each pump: (1) certified pump performance information from the manufacturer. If manufacturer's certified information is unavailable, then pump performance information that is generated by a qualified independent third-party organization using a code or standard of practice acceptable to the executive director may be used;(2) the operating status of each pump;(3) the motor manufacturer, model number, and rated brake horsepower;(4) the impeller manufacturer, model number, size, and design;(5) any change to a cooling tower heat exchange system pump or pumping system in which the change would modify the basis for design pumping capacity; and(6) the effect of any change on the maximum potential flow rate.(f) The owner or operator of any cooling tower heat exchange system using a system to monitor cooling water pump discharge pressure to determine the continuous flow rate for each cooling tower, as specified in § 115.764(e)(2) of this title, shall maintain the following records for each pump: (1) the continuous measurement of cooling water pump discharge pressure;(2) certified pump performance information from the manufacturer. If manufacturer's certified information is unavailable, then pump performance information that is generated by a qualified independent third-party organization using a code or standard of practice acceptable to the executive director may be used;(3) the operating status of each pump;(4) the motor manufacturer, model number, and rated brake horsepower;(5) the impeller manufacturer, model number, size, and design;(6) any change to a cooling tower heat exchange system pump or pumping system in which the change would modify the basis for design pumping capacity; and(7) the effect of any change on the maximum potential flow rate.(g) The owner or operator of each site subject to § 115.761 of this title shall maintain daily records to demonstrate compliance with the tons per calendar year emissions limits specified in § 115.761(a) and (b) of this title, including: (1) flare, vent gas, and pressure relief valve emissions that are subject to Division 1 of this subchapter (relating to Vent Gas Control); and(2) all cooling towers subject to the requirements of § 115.764 of this title.(h) The owner or operator of each site subject to § 115.761 of this title shall maintain hourly records to demonstrate compliance with the one-hour block emissions limits specified in § 115.761(c) of this title, including:(1) flare, vent gas, and pressure relief valve emissions that are subject to Division 1 of this subchapter; and(2) all cooling towers subject to the requirements of § 115.764 of this title.(i) The owner or operator of an affected cooling tower heat exchange system shall develop, implement, and follow a written quality assurance plan (QAP) for the installation, calibration, operation, and maintenance for the monitoring equipment required by this division as follows. (1) The owner or operator shall maintain records of the QAP and any revisions to the QAP on site.(2) Upon written request by the executive director, the QAP required in this paragraph shall be submitted within 30 days for review. The executive director may specify revisions to the QAP.(j) The owner or operator claiming an exemption under § 115.767(4) of this title shall submit written notification to the executive director no later than December 31, 2005.30 Tex.
