"Dehydrator" means dehydrator as defined in 40 CFR 60.5430a, Subpart OOOOa Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution, which is incorporated by reference in R307-210. "Uncontrolled emissions" means actual or potential emissions without consideration of controls. |
| R307-507-3. Applicability |
|
Latest version.
|
|
(1) R307-507 applies to each dehydrator located at a well site as defined in 40 CFR 60.5430a, Subpart OOOOa, Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution. (2) R307-507 shall apply to centralized tank batteries, as defined in R307-506-2. (3) R307-507 does not apply to a dehydrator that is subject to an approval order issued under R307-401-8. |
| R307-507-4. Dehydrator Requirements |
|
Latest version.
|
|
(1) Dehydrators with VOC emissions of four tons of uncontrolled emissions per year or greater, either individually or combined with VOC emissions from storage vessels, shall either be routed to a process unit where the emissions are recycled, incorporated into a product, and/or recovered, or be routed to a VOC control device that is in compliance with R307-508. Dehydrators in operation before January 1, 2018, shall determine applicability with calculated actual emissions. Dehydrators in operation on or after January 1, 2018, shall determine applicability using potential to emit. (2) An owner or operator that is required to control emissions in accordance with R307-507-4(1) shall inspect, at least once a month, each closed vent system, including vessel openings, thief hatches, and bypass devices, for defects that can result in air emissions according to 40 CFR 60.5416a(c). (a) If defects are discovered, the defects shall be corrected or repaired within 15 days of identification. (3) Modification to a well site shall require a re-evaluation of emissions in accordance with R307-507-4(1). (4) After a minimum of one year of operation, controls may be removed if uncontrolled actual emissions, individually or combined with VOC emissions from storage vessels, are less than four tons per year on a rolling 12-month basis. |
| R307-507-5. Recordkeeping |
|
Latest version.
|
|
(1) Records of emission calculations shall be kept for all periods the plant is in operation if a control device is not installed on-site. (2) Records of each closed vent system inspection, including vessel openings, thief hatches, pressure relief devices and bypass devices, shall be kept for three years. (a) Records of each closed vent system inspection, including vessel openings, thief hatches, pressure relief devices and bypass devices, shall include the date of the inspection, the status of each closed vent system, including vessel openings, thief hatches, pressure relief devices and bypass devices, and the date of corrective action taken, if required. |
