§ 66264.1033. Standards: Closed-Vent Systems and Control Devices.
(2)(A) The owner or operator of an existing facility who cannot install a closed-vent system and control device to comply with the provisions of this article on the effective date that the facility becomes subject to the provisions of this article must prepare an implementation schedule that includes dates by which the closed-vent system and control device will be installed and in operation. The controls must be installed as soon as possible, but the implementation schedule may allow up to 30 months after the effective date that the facility becomes subject to this article for installation and startup.
(B) Any unit that begins operation after December 21, 1990, and is subject to the provisions of this article when operation begins, shall comply with the rules immediately (i.e., shall have control devices installed and operating on startup of the affected unit); the 30-month implementation schedule does not apply.
(C) The owner or operator of any facility in existence on the effective date of a statutory or Department regulatory amendment that renders the facility subject to this article shall comply with all requirements of this article as soon as practicable but no later than 30 months after the amendment's effective date. When control equipment required by this article cannot be installed and begin operation by the effective date of the amendment, the facility owner or operator shall prepare an implementation schedule that includes the following information: Specific calendar dates for award of contracts or issuance of purchase orders for the control equipment, initiation of on-site installation of the control equipment, completion of the control equipment installation, and performance of any testing to demonstrate that the installed equipment meets the applicable standards of this article. The owner or operator shall enter the implementation schedule in the operating record or in a permanent, readily available file located at the facility.
(D) Owners and operators of facilities and units that become newly subject to the requirements of this article after December 8, 1997, due to an action other than those described in article (a)(2)(C) of this section must comply with all applicable requirements immediately (i.e., must have control devices installed and operating on the date the facility or unit becomes subject to this article; the 30-month implementation schedule does not apply).
(b) A control device involving vapor recovery (e.g., a condenser or absorber) shall be designed and operated to recover the organic vapors vented to it with an efficiency of 95 weight percent or greater unless the total organic emission limits of Section 66264.1032(a)(1) for all affected process vents can be attained at an efficiency less than 95 weight percent.
(c) An enclosed combustion device (e.g., a vapor incinerator, boiler, or process heater) shall be designed and operated to reduce the organic emissions vented by it by 95 weight percent or greater; to achieve a total organic compound concentration of 20 ppmv, expressed as the sum of the actual compounds, not carbon equivalents, on a dry basis corrected to 3 percent oxygen; or to provide a minimum residence time of 0.50 seconds at a minimum temperature of 760 degrees C. If a boiler or process heater is used as the control device, then the vent stream shall be introduced into the flame zone of the boiler or process heater.
(3) A flare shall be used only if the net heating value of the gas being combusted is 11.2 MJ/scm (300 Btu/scf) or greater if the flare is steam-assisted or air-assisted; or if the net heating value of the gas being combusted is 7.45 MJ/scm (200 Btu/scf) or greater if the flare is non-assisted. The net heating value of the gas being combusted shall be determined by the methods specified in subsection (e)(2) of this section.
(B) A steam-assisted or non-assisted flare designed for and operated with an exit velocity, as determined by the method specified in subsection (e)(3) of this section, equal to or greater than 18.3 m/s (60 ft/s) but less than 122 m/s (400 ft/s) is allowed if the net heating value of the gas being combusted is greater than 37.3 MJ/scm (1,000 Btu/scf).
(C) A steam-assisted or non-assisted flare designed for and operated with an exit velocity, as determined by the methods specified in subsection (e)(3) of this section, less than the velocity, Vmax as determined by the method specified in subsection (e)(4) of this section and less than 122 m/s (400 ft/s) is allowed.

(1) install, calibrate, maintain, and operate according to the manufacturer's specifications a flow indicator that provides a record of vent stream flow from each affected process vent to the control device at least once every hour. The flow indicator sensor shall be installed in the vent stream at the nearest feasible point to the control device inlet but before the point at which the vent streams are combined; and
(A) for a thermal vapor incinerator, a temperature monitoring device equipped with a continuous recorder.

The monitoring frequency shall be daily or at an interval no greater than 20 percent of the time required to consume the total carbon working capacity established as a requirement of Section 66264.1035(b)(4)(C)7, whichever is longer; or
(j) An owner or operator of an affected facility seeking to comply with the provisions of this chapter by using a control device other than a thermal vapor incinerator, catalytic vapor incinerator, flare, boiler, process heater, condenser, or carbon adsorption system is required to develop documentation including sufficient information to describe the control device operation and identify the process parameter or parameters that indicate proper operation and maintenance of the control device.
(2) a closed-vent system shall be designed to operate at a pressure below atmospheric pressure. The system shall be equipped with at least one pressure gauge or other pressure measurement device that can be read from a readily accessible location to verify that negative pressure is being maintained in the closed-vent system when the control device is operating.
(A) an initial leak detection monitoring of the closed-vent system shall be conducted by the owner or operator on or before the date that the system becomes subject to this section. The owner or operator shall monitor the closed-vent system components and connections using the procedures specified in section 66264.1034(b) of this article to demonstrate that the closed-vent system operates with no detectable emissions, as indicated by an instrument reading of less than 500 ppmv above background.
1. closed-vent system joints, seams, or other connections that are permanently or semi-permanently sealed (e.g., a welded joint between two sections of hard piping or a bolted and gasketed ducting flange) shall be visually inspected at least once per year to check for defects that could result in air pollutant emissions. The owner or operator shall monitor a component or connection using the procedures specified in section 66264.1034(b) to demonstrate that it operates with no detectable emissions following any time the component is repaired or replaced (e.g., a section of damaged hard piping is replaced with new hard piping) or the connection is unsealed (e.g., a flange is unbolted).
2. closed-vent system components or connections other than those specified in subsection (l)(1)(B)1. of this section shall be monitored annually and at other times as requested by the Department, except as provided for in subsection (o) of this section, using the procedures specified in section 66264.1034(b) to demonstrate that the components or connections operate with no detectable emissions.
(A) detectable emissions, as indicated by visual inspection, or by an instrument reading greater than 500 ppmv above background, shall be controlled as soon as practicable, but not later than 15 calendar days after the emission is detected, except as provided for in subsection (l)(3)(C) of this section.
(C) delay of repair of a closed-vent system for which leaks have been detected is allowed if the repair is technically infeasible without a process unit shutdown, or if the owner or operator determines that emissions resulting from immediate repair would be greater than the fugitive emissions likely to result from delay of repair. Repair of such equipment shall be completed by the end of the next process unit shutdown.
(n) The owner or operator using a carbon adsorption system to control air pollutant emissions shall document that all carbon that is a hazardous waste and that is removed from the control device is managed in one of the following manners, regardless of the average volatile organic concentration of the carbon:
