R307-511.  Oil and Gas Industry: Associated Gas Flaring.
R307-511-1.  Purpose.
	R307-511 establishes control requirements for the flaring of produced gas associated with well sites.

R307-511-2.  Definitions.
	"Emergency release" means a temporary, infrequent and unavoidable situation in which the loss of gas is uncontrollable or necessary to avoid risk of an immediate and substantial adverse impact on safety, public health, or the environment.  An "emergency" is limited to a short-term situation of 24 hours or less caused by an unanticipated event or failure that is out of the operator's control and is not due to operator negligence.
	"Flaring" means use of a thermal oxidation system designed to combust hydrocarbons in the presence of a flame.
	"Associated Gas" means the natural gas that is produced from an oil well during production operations and is either sold, re-injected, used for production purposes, vented (rarely) or flared.  Low pressure gas associated with the working, breathing, and flashing of oil is not considered associated gas under this definition and shall be controlled in accordance with R307-506 and R307-507.

R307-511-3.  Applicability.
	(1)  R307-511 applies to each producing well 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)  VOC control devices used for controlling associated gas are subject to R307-508.
	(3)  R307-511 does not apply to producing wells that are subject to an approval order issued under R307-401-8.

R307-511-4.  Associated Gas Flaring Requirements.
	(1)  Associated gas from a completed well shall either be routed to a process unit for combustion, routed to a sales pipeline, or routed to an operating VOC control device except for emergency release situations as defined in R307-511-2.

R307-511-5.  Recordkeeping.
	(1)  The owner or operator shall maintain records for releases under R307-511-4(1)(a).
	(a)  The time and date of event, volume of emissions and any corrective action taken shall be recorded.
	(b)  These records shall be kept for a minimum of three years.
