Control of emissions of organic material.
Tulsa Revised Ordinances tit. 17, § 714
in effectSection 714. - Control of emissions of organic material.
A. Purpose. It is the purpose of this regulation to control the emissions of organic vapors during the storage, transport or dispensing of organic materials.
B. Storage of volatile organic compounds - four hundred (400)—forty thousand (40,000) gallons (nine and one-half (9.5)—nine hundred fifty-three (953) bbls).
1. No person shall store or permit the storage of gasoline or other volatile organic compounds in any stationary storage container with a nominal capacity greater than four hundred (400) gallons (nine and one-half (9.5) bbls) and less than forty thousand (40,000) gallons (nine hundred fifty-two and four-tenths (952.4) bbls) unless such container is equipped with a submerged fill pipe or is bottom filled. No person shall store or permit the storage of gasoline or other volatile organic compounds in any stationary storage container with a nominal capacity greater than two thousand (2,000) gallons (forty-seven and one-half (47.5) bbls) and less than forty thousand (40,000) gallons (nine hundred fifty-two and four-tenths (952.4) bbls) unless such container is equipped with a vapor control system that has an efficiency of no less than ninety (90) percent by weight of the volatile organic compounds contained in the displaced vapors and is equipped with a pressure relief valve in the atmospheric vent system which maintains a pressure of sixteen (16) ounces per square inch and one-half (½) ounce per square inch vacuum.
2. The vapor recovery system shall include the following:
a. A vapor-light return line from the storage container to the delivery vessel and a system that will ensure that the vapor return line is connected before gasoline or volatile organic compounds can be transferred into the container (i.e., poppeted connectors from the storage container to the delivery vessel);
b. A float vent valve assembly must be installed in the vapor return/vent line on new and existing dual point installations; however, for coaxial installations on existing stations, a vent sleeve extending six (6) inches below the top of the tank will be allowed; sleeves may be equipped with a one-sixteenth ( 1/16 )-inch air bleed hole;
c. The cross sectional area of the vapor recovery line must be at least half of the cross sectional area of the liquid delivery line; and
d. Other equipment that has a total collection efficiency no less than ninety percent (90%) by weight of the total hydrocarbon compounds in the displaced vapor, provided that approval of the proposed design, installation and operation is obtained from the Director prior to start of construction.
3. Exemptions to this regulation may be granted, provided that the owner or operator shows to the satisfaction of the Director that the container is used exclusively for agricultural purposes or that the facility, based on the most current twelve (12) months' data, dispenses one hundred twenty thousand (120,000) gallons per year or less.
4. Compliance with this subsection must be accomplished by the affected owner or operator by October 1, 1987.
C. Emission of gasoline vapors from gasoline transport vessels.
1. The vapor-laden vessels shall meet the following requirements:
a. The transport vessel must be maintained so as to be vapor tight except during sampling, gauging or inspection; these activities shall not be done while loading or unloading; and
b. The transport vessel must be equipped, operated and maintained to receive vapors from the gasoline service stations and retain these vapors until they are delivered to an authorized vapor recovery or disposal system.
2. Compliance with this subsection must be accomplished by the affected owner or operator by October 1, 1987.
D. Compliance for vapor tightness.
1. Each gasoline transport vessels delivering or receiving gasoline in the City of Tulsa and Tulsa County must be tested one (1) time per year for vapor tightness. The test must be consistent with Appendix "A," EPA Guidelines Series Document, "Control of Volatile Organic Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems," EPA 450/2-78-051, or an equivalent method as determined by the Director.
a. Tests shall be performed by the owner or a reputable transport service company. Service companies methods and procedures must be certified by Tulsa City-County Health Department.
b. A tag showing the date of pressure test and date of certification must be posted on the rear panel of tank. These tags will be supplied by the Tulsa City-County Health Department.
c. Terminal owners or operators shall not knowingly allow the gasoline transport to be filled at the terminal if the certification tag is out of date or missing.
2. To ensure the integrity of the program outlined in C.1, the Tulsa City-County Health Department will conduct periodic vapor leak testing. This testing must be consistent with Appendix "B," EPA Guidelines Series Document, "Control of Volatile Organic Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems," EPA 450/2-78-051.
a. Vessels with defective equipment such as boots, seals, hoses and leaky pressure or vacuum relief valves must be repaired within five (5) days.
b. Vessels which fail the vapor test by having leaks that exceed five thousand (5,000) ppm must be repaired within ten (10) days.
c. Repairs must be made by the owner or a supplier certified by Tulsa City-County Health Department.
d. Letters from the vessel owner certifying compliance, with proof of repair attached, must be sent to the Tulsa City-County Health Department within five (5) days.
e. Failure to comply with any provision of this subsection will subject the vessel to sanctions which may include removal from service.
3. Compliance with this subsection must be accomplished by the affected owner or operator by October 1, 1987.
E. Loading. All loading of the above organic material storage tanks shall be conducted by tight fill.
F. Exemptions:
1. Methane (CH 4 ).
2. Any organic material with a vapor pressure less than one and one-half (1.5) psia under actual storage temperatures and pressures.
3. Crude oil defined as follows: produced, non-refined hydrocarbon which has a gravity equal to or less than fifty (50) API gravity at sixty degrees (60°) Fahrenheit, as measured in the stock tank and when flashed to the atmospheric stock tank from the final release separator and/or treating facility, loses no more than one and one-half (1.5) percent of the stock tank volume or twenty-five (25) standard cubic feet per barrel of stock tank oil.
4. The storage and/or loading of organic materials used for agricultural purposes on farms or ranches.
