The Federal Register describes specific criteria which must be met within the program. This document describes the leak detection program. Each of the specific requirements will be met. Namely, this program describes: The continuous VCM detection system which is used by the plant. The portable hydrocarbon detectors which are used by the plant. The calibration and maintenance procedures for the above equipment. The Routine Leak Patrols and procedure when a leak is found by the portable hydrocarbon detector. The location of the continuous monitoring points which are used for leak detection. The criteria which will be used to identify the presence of an action level and a leak. The action plan which will be used to eliminate a leak after it has been detected. VAB.0001153907 4 LEAK DETECTION AND ELIMINATION PROGRAM ABERDEEN CHEMICAL PLANT B. VINYL CHLORIDE CONTINUOUS MONITORING SYSTEM Introduction The concentration of vinyl chloride in the atmosphere is continuously monitored by four flame ionization chromatographs, each of which is operated continuously. Each chromatograph is a Honeywell Model 1000 Process Gas Chromatograph manufactured by: Honeywell Systems, Inc. 6625 McGrew Street t Houston, Texas Each chromatograph sequentially measures, on a continuous basis, the vinyl chloride content in air samples taken from ten different locations. A total of forty (40) locations are monitored throughout the plant continuously and the concentrations at each point are recorded. Analytical Technique The Flame Ionization Detector used in the Honeywell 1000 Process Gas Chromatographs has a lower detection limit of 0.1 part per million. The special-purpose elements of the FID chromatograph are a flame cell, an FID Electrometer Assembly, a Temperature Control/Inverter Assembly, and a plug-in FID Amplifier Module which mounts in the Control Section. The flame cell consists of an ignitor wire, a hydrogen-fed burner, and an electron collector. Within the cell, hydrogen combustion occurs in an electrical field created by the voltage from the ionization inverter. Because of the carbon-free property of hydrogen, ionization occurs only when a carbon-bearing sample is injected into the flame. Ionization causes current to flow from the collector in direct proportion to the amount of the hydrocarbon elements present in the sample. The output current from the flame cell is routed through the Electrometer (Preamp) in the Analyzer, and is applied to the input of the FID Amplifier in the Control Section. The gain is made available for external recording. The FID Electrometer Assembly is physically divided into two major subassemblies: the Power Supply-Electrometer P.C. Card Assembly, and the Electrometer P.C. Card Assembly. The electrometer power supply accepts +_ 20 volt inputs from the Control Section power supply, and produces regulated plus and minus 15 volt outputs for operation of the electrometer circuits and the inverter located on the Temperature Control/Inverter P.C. Card Assembly. The inverter output is a -100 volt ionization potential which is applied to the base (burner) of the flame cell. VAB.0001153908
