Utah Admin. Code R315-265-1088 - Air Emission Standards for Tanks, Surface Impoundments, and Containers - Standards: Closed-Vent Systems and Control Devices

(a) Section R315-265-1088 applies to each closed-vent system and control device installed and operated by the owner or operator to control air emissions in accordance with standards of Sections R315-265-1080 through R315-265-1090.

(b) The closed-vent system shall meet the following requirements:

(1) The closed-vent system shall route the gases, vapors, and fumes emitted from the hazardous waste in the waste management unit to a control device that meets the requirements specified in Subsection R315-265-1088(c).

(2) The closed-vent system shall be designed and operated in accordance with the requirements specified in Subsection R315-265-1033(j).

(3) If the closed-vent system includes bypass devices that could be used to divert the gas or vapor stream to the atmosphere before entering the control device, each bypass device shall be equipped with either a flow indicator as specified in Subsection R315-265-1088(b)(3)(i) or a seal or locking device as specified in Subsection R315-265-1088(b)(3)(ii). For the purpose of complying with Subsection R315-265-1088(b), low leg drains, high point bleeds, analyzer vents, open-ended valves or lines, spring-loaded pressure relief valves, and other fittings used for safety purposes are not considered to be bypass devices.

(i) If a flow indicator is used to comply with Subsection R315-265-1088(b)(3), the indicator shall be installed at the inlet to the bypass line used to divert gases and vapors from the closed-vent system to the atmosphere at a point upstream of the control device inlet. For Subsection R315-265-1088(b), a flow indicator means a device which indicates the presence of either gas or vapor flow in the bypass line.

(ii) If a seal or locking device is used to comply with Subsection R315-265-1088(b)(3), the device shall be placed on the mechanism by which the bypass device position is controlled, for example, valve handle, damper lever, if the bypass device is in the closed position such that the bypass device cannot be opened without breaking the seal or removing the lock. Examples of such devices include, but are not limited to, a car-seal or a lock-and-key configuration valve. The owner or operator shall visually inspect the seal or closure mechanism at least once every month to verify that the bypass mechanism is maintained in the closed position.

(4) The closed-vent system shall be inspected and monitored by the owner or operator in accordance with the procedure specified in Subsection R315-265-1033(k).

(c) The control device shall meet the following requirements:

(1) The control device shall be one of the following devices:

(i) A control device designed and operated to reduce the total organic content of the inlet vapor stream vented to the control device by at least 95 percent by weight;

(ii) An enclosed combustion device designed and operated in accordance with the requirements of Subsection R315-265-1033(c); or

(iii) A flare designed and operated in accordance with the requirements of Subsection R315-265-1033(d).

(2) The owner or operator who elects to use a closed-vent system and control device to comply with the requirements of Section R315-265-1088 shall comply with the requirements specified in Subsections R315-265-1088(c)(2)(i) through R315-265-1088(c)(2)(vi).

(i) Periods of planned routine maintenance of the control device, during which the control device does not meet the specifications of Subsections R315-265-1088(c)(1)(i), R315-265-1088(c)(1)(ii), or R315-265-1088(c)(1)(iii), as applicable, shall not exceed 240 hours per year.

(ii) The specifications and requirements in Subsections R315-265-1088(c)(1)(i), R315-265-1088(c)(1)(ii), or R315-265-1088(c)(1)(iii) for control devices do not apply during periods of planned routine maintenance.

(iii) The specifications and requirements in Subsections R315-265-1088(c)(1)(i), R315-265-1088(c)(1)(ii), or R315-265-1088(c)(1)(iii) for control devices do not apply during a control device system malfunction.

(iv) The owner or operator shall demonstrate compliance with the requirements of Subsection R315-265-1088(c)(2)(i), for example, planned routine maintenance of a control device, during which the control device does not meet the specifications of Subsections R315-265-1088(c)(1)(i), R315-265-1088(c)(1)(ii), or R315-265-1088(c)(1)(iii), as applicable, shall not exceed 240 hours per year, by recording the information specified in Subsection R315-265-1090(e)(1)(v).

(v) The owner or operator shall correct control device system malfunctions as soon as practicable after their occurrence in order to minimize excess emissions of air pollutants.

(vi) The owner or operator shall operate the closed-vent system such that gases, vapors, and fumes are not actively vented to the control device during periods of planned maintenance or control device system malfunction, for example, periods if the control device is not operating or not operating normally, except in cases if it is necessary to vent the gases, vapors, or fumes to avoid an unsafe condition or to implement malfunction corrective actions or planned maintenance actions.

(3) The owner or operator using a carbon adsorption system to comply with Subsection R315-265-1088(c)(1) shall operate and maintain the control device in accordance with the following requirements:

(i) Following the initial startup of the control device, all activated carbon in the control device shall be replaced with fresh carbon on a regular basis in accordance with the requirements of Subsections R315-265-1033(g) or R315-265-1033(h).

(ii) All carbon that is a hazardous waste and that is removed from the control device shall be managed in accordance with the requirements of Subsection R315-265-1033(m), regardless of the average volatile organic concentration of the carbon.

(6) If the owner or operator and the Director do not agree on a demonstration of control device performance using a design analysis then the disagreement shall be resolved using the results of a performance test performed by the owner or operator in accordance with the requirements of Subsection R315-265-1088(c)(5)(iii).
