Emission requirements of 61.64 (a)(2), (b), (c), (d) and 61.65 (b)(1)(H), (b)(5), (b)(6)(H), (6)(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 multi point gas chromatograph. The exhaust gas from the incinerator is also sampled periodically (grab sample) and analyzed for vinyl chloride. Results from these samples are given in Table I. 61.70 (c)(2)(i) The emission level prescribed in 61.64 (e) is attained by a stripping opera tion. The plant produces only one type of resin, that by the suspension process. The vinyl chloride content found in all samples required in 61.70 (c)(2)(i), averaged over each calendar day and weighted according to the quantity of each grade of resin processed by the strippers that calendar day is given in Table II. 61.70 (c)(3) Compliance with 61.64 (a)(2) is attained by using standard operating proce dures to strip the resin to less than 400 ppm vinyl chloride and purge the vinyl chloride from the reactor vapor space. These procedures are described in Section VI of the Compliance Manual which was submitted to EPA Region IV on August 14, 1978. i * Pini.n.w^miiwpmrn mu mqmi VAB.0001145642 * C0HftDmiAL INCINERATOR STACK SAMPLES SEMIANNUAL REPORT SEPTEMBER 1, 1983 THROUGH FEBRUARY 29, 1984 CONOCO CHEMICALS COMPANY ABERDEEN, MISSISSIPPI DATE OF SAMPLE 09/07/83 09/13/83 09/20/83 09/27/83 10/04/83 10/12/83 10/18/83 10/25/83 11/01/83 11/08/83 11/16/83 11/22/83 11/28/83 12/07/83 12/14/83 12/21/83 12/29/83 9 01/04/84 01/10/84 01/17/84 01/24/84 01/31/84 02/06/84 02/13/84 02/20/84 02/29/84 Si- PPM VCM VOLUME <-0.1 1.7 C 0.1 < 0.1 0.9 1.0 0.9 1.8 C 0.1 <, 0.1 0.4 0.2 C 0.1 <0.1 0.7 < o.l <0.1 <.0.1 < o.l ,0.1 <0.1 <0.1 <01 toil 01 .8e, k VAB.0001145643 im mm TABLE II SEMIANNUAL REPORT SEPTEMBER 1, 1983 THROUGH FEBRUARY 29, 1984 CONOCO CHEMICALS COMPANY ABERDEEN, MISSISSIPPI WEIGHTED AVERAGE RESIDUAL VINYL CHLORIDE CONCENTRATION IN STRIPPED SLURRY PPM, VCM, DRY BASIS SEPT. 83 1 138 2 217 3 145 4 156 5 205 6 212 7 218 8 155 9 184 10 186 11 251 12 198 13 185 14 211 15 209 16 272 17 257 18 212 19 193 20 167 21 162 22 221 23 200 24 263 25 176 26 148 27 169 28 163 29 233 30 206 31 OCT. 83 319 235 319 293 392 180 223 266 183 166 151 118 152 220 149 187 160 162 175 131 179 206 162 134 171 282 225 269 161 222 192 MONTH NOV. 83 DEC. 83 JAN. 84 136 259 244 691 200 245 239 466 262 177 313 326 368 217 233 320 195 203 181 185 194 199 201 140 250 265 246 207 219 271 215 200 186 203 240 218 232 233 240 204 345 204 196 194 435* 256 . 218 458 207 No Production 232 No Production 238 213 196 262 182 212 513 162 202 175 287 244 172 185 146 241 177 230 164 234 188 206 247 207 295 200 187 172 268 168 377 201 286 175 165 206 213 189 214 167 FEB. 84 182 182 185 211 281 188 268 228 235 252 364 163 198 199 171 175 210 224 193 142 245 186 182 173 213 180 246 220 181 h .M VAB.0001145644 TM .-- --in-n -
