SITE RELEASE AND TRANSFER INFORMATION FORTRICHEMICALS Not applicable. V. SITE RELEASE AND TRANSFER INFORMATION FOR NON-TRI CHEMICALS While analytical methods have improved over time, large variability still exists for certain matrices and compounds, so data available for this report is mostly of qualitative nature. Although limited `monitoring data exists, most emission and waste estimates are based upon process models and engineering calculations. Engineering calculations, however, have limitations with respect to fluorochemicals because fluorochemical losses were not always included in the analysisofeach intermediate step. The accuracyofthe emissions data submitted varies due to several factors. Batch process systems are difficult to measure due to quickly changing process conditions, venting pressures and difficulty in isolating processes to take measurements. Additionally, the unique characteristicsofthese compounds cause them to behave differently from conventional compounds, and physical chemical data properties are not available for all intermediate reaction steps in the past. A. ON-SITE AIR RELEASES ALL PLANTS - Fugitive emissions may occur from vacuum charging from drums, sampling from reactors, drumming of product/intermediate, flaking monomer, drying operations. mMaatteerriiaal.ls mIandyusbterihaalnhdylgeidenineamomnoilttoerninorg shoalsidbesteantec;ovnadpuocrtsedarfeorprsoodmuececdomfprooumnmdosl.teSnome `minor amounts of these compounds have been detected as fugitive emissions during industrial hygiene exposure testing.
