100 GENERAL

101 - PURPOSE: To limit emissions from the loading of organic liquids.

110 - EXEMPTION, LOW VAPOR PRESSURE ORGANIC LIQUIDS: The loading of organic liquids having a vapor pressure less than 0.5 psia under actual loading conditions is exempt from this rule.


200 DEFINITIONS

201 - BACKGROUND: A reading as methane on a portable hydrocarbon detection instrument which is determined at least three (3) meters upwind from the affected device to be inspected and uninfluenced by any specific emission point.

202 - BULK PLANT: An organic liquid distribution facility which receives organic liquid from a refinery or bulk terminal by tank truck and distributes the organic liquid by tank truck to wholesale and retail facilities.

203 - BULK TERMINAL: An organic liquid distribution facility which receives organic liquid from the refinery by pipeline, ship, or barge.

204 - EXEMPT COMPOUND: For the purposes of this rule, "exempt compound" has the same meaning as in Rule 101--GENERAL PROVISIONS AND DEFINITIONS.

205 - LEAK FREE: A liquid leak of less than three drops per minute excluding losses which occur upon disconnecting transfer fittings, provided such disconnect losses do not exceed one (1) fluid ounce, averaged over three disconnects.

206 - LOADING FACILITY: Any stationary source with organic liquid loading equipment.

207 - VAPOR TIGHT: A concentration of total organic compounds, measured one (1) cm from any source, which does not exceed 10,000 ppm (expressed as methane) above background, as determined by a method specified in Section 501.3.

208 - VOLATILE ORGANIC COMPOUND (VOC): For the purposes of this rule, "volatile organic compound" has the same meaning as in Rule 101--GENERAL PROVISIONS AND DEFINITIONS.


300 STANDARDS

301 - CALIFORNIA AIR RESOURCES BOARD CERTIFIED VAPOR RECOVERY SYSTEM: Effective May 31, 1991 a person shall not load organic liquids into any tank truck, trailer, or railroad tank car from any loading facility unless the loading facility is equipped with an ARB certified vapor collection and disposal system.

302 - VAPOR RECOVERY REQUIREMENTS; BULK TERMINALS: A person shall not transfer or permit the transfer of organic liquids into any tank truck, trailer or railroad tank car unless the emissions to the atmosphere do not exceed 0.08 pounds of VOC per one thousand (1,000) gallons of organic liquids transferred as determined by a method specified in Section 501.1.

303 - VAPOR RECOVERY REQUIREMENTS; BULK PLANTS: A person shall not transfer or permit the transfer of organic liquids into any tank truck, trailer or railroad tank car unless the emissions to the atmosphere do not exceed 0.6 pounds of VOC per one thousand (1,000) gallons of organic liquids transferred as determined by a method specified in Section 501.1.

304 - EQUIPMENT MAINTENANCE: All equipment associated with loading facilities shall be maintained to be leak free and vapor tight.

305 - VAPOR DIAPHRAGM REQUIREMENTS: Diaphragms used in vapor storage tanks shall be maintained such that the volatile organic compound concentration in the airspace above the diaphragm does not exceed 3,000 parts per million, expressed as methane, as determined by a method specified in Section 501.2.


400 ADMINISTRATIVE REQUIREMENTS

401 - COMPLIANCE SCHEDULE: Any person operating equipment which does not comply with Section 301 on April 30, 1991 shall request ARB certification by May 31, 1991. Compliance with Section 401 shall constitute compliance with Section 301 unless it is determined that the equipment does not comply with section 303.


500 MONITORING AND RECORDS

501 - TESTING PROCEDURE: A result by any of the below listed test methods which shows non-compliance with any provision of the rule shall constitute a violation of the rule.

502 - RECORDS: Persons subject to this rule shall maintain records of the results of any testing performed in accordance with Section 501 for two years and make those records available for review by the Air Pollution Control Officer upon request.
