Danny Jackson North Air Emissions Sections Mississippi Department of Natural Resources Bureau of Pollution Control P. 0. Box 10385 Jackson, MS 39209 Dear Mr. Jackson: As required by 40 CFR, Section 61.70, attached is the quarterly report for the Aberdeen, Mississippi facility of Vista Polymers, a division of Vista Chemical Company. This report covers the period from September 1, 1989 through November 30, 1989. Please direct any questions to Mr. Frank G. Jeanson at (601) 3693637. Sincerely, R. W. Seymour Plant Manager rah attachment cc: RBN, FGJ, JCL, VAB.0001115984 61.70 (a) Quarterly reports which apply to this subpart will be submitted on March 15, June 15, September 15 and December 15 of each year. H J.Q, (fr). No new source or Initial report is required for this reporting period. No emissions from the control device (incinerator) exceeded 10 ppm vinyl chloride averaged over any 3-hour period during this reporting period. Emission requirements of 61.64 (a)(1), (b), (c), (d) and 61.65 (b)(i)(ii), b(5), (b)(6)(ii), (b)(9)(H) are met by collecting, containing and incinerating vents from these areas prior to their release to the atmosphere. The exhaust gas from the incinerator is measured continuously with a Honeywell chromatograph. The exhaust gas from the incinerator is also sampled weekly (grab sample) and analyzed for vinyl chloride. There were 2184 3-hour periods for which the average emissions were determined during the reporting period. The gas chromatograph in the incinerator exhaust gas was used to calculate the 3-hour period average emissions. 61.70 (cH2) A report is not required as the stripping operation occurs in the reactor. See reporting for 61.70 (c)(4). A report is not required as the stripping operation occurs in the reactor. See reporting for 61.70 (c)(4). The Aberdeen Chemical Plant uses a batch suspension polymerization process producing a single grade of FVC resin. The stripping operation takes place in the reactor. Stripped slurry batches are sampled as prescribed by this section. VAB.0001115985 Quarterly Report - Vista Polymers A The vinyl chloride content of each sample is determined by test method 107 as prescribed in 61.67 (g)(3). Compliance with 61.64 (f) is attained by operating under the procedures approved by EPA Region IV on March 27, 1986, and not according to the procedure prescribed in Section 61.67 (g)(6). There were ninety-one, twenty-four hour average combined reactor opening loss and emissions from all sources following the reactor used as a stripper determined during the reporting period. No twenty-four hour average combined reactor opening loss and emissions from all sources following the reactor used as a stripper exceeded the limits prescribed in 61.64 (f). A performance test (leak detection survey) as required by this section was completed in November, 1989 on 260 valves in VOC service. The valves were cheeked in accordance with Test Method 21: Volatile Organic Compound Leaks. The readings of all 260 valves never reached or exceeded the specified 10,000 ppm level defined as a leak under 61.65 (b)(8)(ii)(B). Therefore, there are no recordable leaks. Since the plant has demonstrated to operate a process in which there are less than 2.0 percent leaking valves, the plant is exempted from 61.242-1 (d), 61.242-7 (a) (b), and (c), 61.246 and 61.247 of Subpart V. The piping from the Old Module receivers to the incinerator was monitored in November, 1989 using test method 21 of Subpart V and no readings reached or exceeded the 500 ppm limit as prescribed by 61.242-11 (f)(3).
