9/26/89, 9/11/90, 6/8/93)

A. Applicability

The provisions of this rule shall apply to the production,

gathering, separation and processing of crude oil and

natural gas, and the storage and transfer of petroleum

material and reactive organic compound (ROC) liquids.

B. Definitions

The following definitions apply to Rules 71.1, 71.2, 71.3,

and 71.4.

1. "Appropriate analyzer": A hydrocarbon analyzer that

meets the requirements of EPA Reference Method 21 and

is calibrated with methane.

2. "Automatic Bleeder Vent": A floating roof vent that

automatically vents air only during initial filling

operations and during subsequent landings of the roof.

3. "Bottom-Loaded": An ROC liquid delivery vessel shall

be considered to be bottom-loaded when the liquid

transfer and vapor return lines have separate,

independent, and dedicated attachments on the truck or

tank, when the inlet is flush with the container

bottom, and when the truck and trailer hatches remain

closed during liquid transfer.

4. "Containment berm": A structure used solely as

secondary containment for emergency spills from a tank

or other device.

5. "Crude oil": Any naturally ocurring, unrefined

petroleum liquid.

6. "Custody transfer": The transfer of produced crude

oil and/or condensate, after separation and/or

treatment in production operations, from storage tanks

or automatic transfer facilities to pipelines or any

other form of transportation.

7. "Drilling operations pit": A pit used to receive rock

cuttings, waste drilling fluids, and water run off from

around a drilling rig (DOP Reserve Pit) or a pit used

to accept well production for up to 48 hours until the

well is brought on stream (DOP Temporary Pit).

8. "Emergency Pit": A pit used less than thirty (30)

days per year to contain emergency releases of

petroleum material. An emergency pit is dry when not

in use.

9. "First stage production sump": A sump that receives a

stream of petroleum material directly from wells or a

field gathering system.

10. "Gasoline": Any petroleum distillate having a Reid

vapor pressure of 4.0 pounds per square inch or

greater, which is sold or intended for sale for use in

motor vehicles or engines and is commonly or

commercially known or sold as gasoline.

11. "Leak":

a. A leak exists when a reading in excess of 10,000

ppm, as methane, above background, is obtained

using an appropriate portable hydrocarbon analyzer

and when sampling is performed according to the

procedures specified in EPA Method 21 - Appendix A

40 CFR section 3.2.1., or

b. A leak exists when the dripping of liquid

containing reactive organic compounds at a rate of

more than three (3) drops per minute is observed.

A "leak" is not a gaseous emission from pressure relief

devices on tanks or ROC delivery vessels when the

process pressure exceeds the limit specified for the

device.

12. "Loading Facility": Any aggregation or combination

of organic liquid loading equipment which is located so

that all the organic liquid loading outlets for such

aggregation or combination of loading equipment can be

encompassed within any circle of 300 feet in diameter.

13. "Modified Reid vapor pressure": The Reid vapor

pressure measured at tank storage temperatures using

Test Method for Vapor Pressure for Petroleum Products,

ASTM D 323-82.

14. "Petroleum material": Liquids resulting from

petroleum production operations that contain more than

5 milligrams per liter of reactive organic compound

(ROC) material. This definition does not include

refined petroleum liquids such as lube oils or

gasoline.

15. "Petroleum production permit unit": Any aggregation

of equipment used exclusively for the production,

gathering and separation of crude oil and natural gas

which is included on a single Permit to Operate issued

by the Air Pollution Control Officer or is defined as a

single stationary source.

16. "Pit": A receptacle, formed primarily of earthen

materials, although it may be lined with artificial

materials, used to receive intermittent flows of

petroleum material or crude oil. Neither a sample box

of less than two (2) square feet in horizontal surface

area nor a containment berm shall be considered a pit.

17. "Pond": A receptacle, formed primarily of earthen

materials, although it may be lined with artificial

materials, used to contain produced water from

petroleum production processes for disposal or re-use.

Ponds are not used for oil/water separation or

evaporation.

18. "Produced water": Water associated with the

production, gathering, separation and processing of

crude oil.

19. "Reactive organic compound (ROC) liquid": Any

reactive organic compound as defined in Rule 2 of these

Rules.

20. "ROC Liquid Delivery Vessel": A truck, trailer or

railroad car with a storage container carrying ROC

liquid or ROC liquid vapors used to transport ROC

liquids including petroleum products. A vacuum truck

that transfers less than 7,000 gallons of ROC liquid

per load using a vacuum created by a pump permanently

installed on the truck tractor or trailer shall not be

considered to be an ROC delivery vessel.

21. "Second and third stage sump": A sump that receives

a stream from one or more previous stage separation

processes.

22. "Storage tank": Any storage container, reservoir or

tank used for the storage of organic liquids

23. "Submerged fill pipe": Any fill pipe or discharge

nozzle which meets any of the following conditions:

a. The discharge opening is entirely submerged when

the liquid level is six (6) inches above the

bottom of the container.

b. When applied to a container which is loaded from

the side, the discharge opening is entirely

submerged when the liquid level is 18 inches above

the bottom of the container.

c. When applied to a container which is loaded from

the bottom, the discharge opening is entirely

submerged when the liquid level is six (6) inches

above the bottom of the container.

24. "Sump": A receptacle, formed primarily of earthen

materials, although it may be lined with artificial

materials, in continuous use for separating oil, water,

sand or other material in petroleum production

operations.

25. "Tank": A container, constructed primarily of

nonearthen materials, used for the purpose of storing

or holding petroleum material, or for the purpose of

separating water and/or gas from petroleum material.

26. "Tank battery": Any tank, or any aggregation of

tanks. An aggregation of tanks will be considered a

tank battery only if the tanks are located so that no

one tank is more than 150 feet from any other tank,

edge to edge.

27. "Vapor loss control efficiency": A comparison of

controlled emissions to those emissions which would

occur from a geometrically similar fixed or cone roof

tank in the same product service without a vapor

control system. Base line emissions shall be

calculated by using the criteria outlined in EPA

document AP-42.

28. "Vapor recovery system": Any reactive organic

compound vapor control system which is designed to

prevent the release or venting of reactive organic

compound gases to the atmosphere under normal operating

conditions.

29. "Wash tank": Any tank used for the purpose of the

primary separation of crude oil from petroleum

material.

30. "Wastewater separator": Any mechanical device used

to separate crude oil and other material from produced

water in petroleum production operations.

31. "Well cellar": A lined or unlined area around one or

more oil wells, allowing access to the wellhead

components for servicing and/or installation of blowout

prevention equipment.
