100 GENERAL

101 PURPOSE: To limit emissions of volatile organic compounds from leaking components including but not limited to: flanges and affected devices which have the potential to vent to the atmosphere at chemical plants that manufacture synthetic organic chemicals and polymers.

102 EXEMPTION, VACUUM CONDITION: The provisions of this rule shall not apply to affected devices or flanges which are part of a system which is operating at 5 kPa (kilopascals) (0.7 psi) or greater below atmospheric pressure.

103 EXEMPTION, VAPOR PRESSURE: The routine monitoring requirements of Section 302 shall not apply to those volatile organic compounds with a vapor pressure less than or equal to 0.3 kPa at 20oC (0.05 psia at 68oF) as determined by methods specified in Section 501.5.

200 DEFINITIONS

201 AFFECTED DEVICES: Including but not limited to valves, pumps, compressors, open-ended lines, sampling connections, agitators and pressure relief devices.

202 AGITATOR: Any device or apparatus with an external shaft used to stir, blend, shake, or mix process streams containing VOC.

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

204 CHEMICAL PLANT: A chemical plant is any plant producing organic chemicals and/or manufacturing products by organic chemical processes subject to Rule 201.

205 COMPRESSOR: A machine used to compress, or increase pressure on, gases.

206 ESSENTIAL AFFECTED DEVICE OR FLANGE: An affected device or flange which cannot be taken out of service without shutting down the process unit it serves.

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

208 FLANGE: A projecting rim on a pipe or piping component used to attach it to another piping detail.

209 HEAVY LIQUID: A fluid with vapor pressure less than or equal to 0.3 kPa at 20oC (0.04 psia at 68oF) as determined by the methods specified in Section 501.5.

210 INACCESSIBLE AFFECTED DEVICE OR FLANGE:

211 LEAK: A leak is :

212 LEAK MINIMIZATION: The tightening, adjustment, or addition of packing material to any affected device or flange, or the replacement of any affected device or flange, or the addition or replacement of gaskets to flanges which reduces the rate, appearance, or concentration of leakage from the affected device or flange.

213 LIGHT LIQUID: A fluid with vapor pressure greater than 0.3 kPa at 20oC (0.04 psia at 68oF) as determined by the methods specified in Section 501.5.

214 PRESSURE RELIEF DEVICE: A device used to relieve pressure in applications where process pressure may exceed the maximum allowable working pressure of the processing equipment.

215 PROCESS UNIT: The group of all equipment in a continuous line involved in the manufacturing or processing of synthetic organic chemicals or polymers.

216 PUMP: A machine or device for transferring a liquid or gas from a source or container through tubes or pipes to another container or receiver.

217 VALVE: Any device that regulates flow of a fluid in a piping system by means of an external actuator acting to permit or block passage of a fluid including the attached flange and the flange seal.

218 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 AFFECTED DEVICES AND FLANGES:

302 INSPECTION REQUIREMENTS: Each affected device or flange handling volatile organic compounds shall be inspected for leaks according to the following schedule:

303 REPAIR REQUIREMENTS:

304 INACCESSIBLE AFFECTED DEVICES AND FLANGES: Inaccessible affected devices and flanges shall be exempt from provisions of Section 302, provided:

400 ADMINISTRATIVE REQUIREMENTS

401 VIOLATION: Any leak originally identified by the Air Pollution Control Officer is a violation.

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 RECORD KEEPING: A person subject to this rule shall maintain records of inspections for two years and make inspection records available for review by the Air Pollution Control Officer upon request.
