RULE 344 - PETROLEUM SUMPS, PITS AND WELL CELLARS
(Adopted 11/10/1994)

A. Applicability

This rule applies to sumps, pits and well cellars at facilities where petroleum is produced, gathered, separated, processed or stored.

B. Exemptions

C. Definitions

See Rule 102 for definitions not restricted to interpretation of this Rule.

"Capture efficiency" means the weight per unit time of ROC entering a capture system and delivered to a control device divided by the weith per unit time of total ROC generated by the source of ROC expressed as a percentage.

"Control" means the reduction, by destruction or removal, of the amount of ROCs in a gas stream prior to discharge to the atmosphere.

"Control efficiency" means the percentage of ROCs entering control equipment that is not present in the exhaust of that control equipment to the atmosphere.

"Defect" means a condition, including but not limited to a tear, hole or lack of required vapor-tightness, that creates a substantial chance of reducing the effectiveness of the control device.

"Facility" means a structure, building, oil lease, or operation, that has one or more permitted pieces of equipment.

"Fixed Roof Cover" means any cover that is not in contact with a liquid surface, but is placed over and completely encloses the liquid surface.

"Floating Cover" means any cover that floats on a liquid surface and prevents evaporation of the liquid under the cover into the atmosphere.

"Overall efficiency" means the emission reduction, expressed as a percentage, that results from the combined effect of capture and control of ROCs that would be emitted to the atmosphere from a container in the same product service without capture and control of emissions.

"Pit" means a basin the purpose of which is collection of emergency or intermittent streams of liquid under normal operations.

"Primary Sump" means any sump that receives a stream of crude oil and produced water directly from one or more oil production wells or field gathering systems.

"Post-primary Sump" means a sump that receives a stream from one or more previous separation processes.

"Post-Tertiary Sump" means a sump that receives a liquid stream that has undergone three or more previous separation processes.

"Sump" means a lined or unlined surface impoundment or depression in the ground that, during normal operations, is used for separating oil, water, and solids in oil production operations.

"Vapor tight" means that a seal or closure prevents the emission of volatile organic compounds which would cause an appropriate analyzer to register more than 10,000 parts per million by volume expressed as methane.

"Well cellar" means a lined or unlined containment into which one or more wellheads are installed. For the purposes of this rule, well cellars are not sumps or pits.
