The evaporator emission levels which would ultimately be released to the atmosphere are expected to be minimal due to the use of the condenser/activated charcoal filter emission control system. Emissions from the evaporator would be primarily air and water vapor at 3000F, with very small amounts of hydrocarbons. These gases would pass through a shell-and-tube design heat exchanger cooled with water from the wastewa- ter holding tank. The gases not condensed out by the heat exchanger system would pass through an activated charcoal filter to remove any remaining traces of hydrocarbons. The condensate would be returned to the wastewater holding tank. Emissions from each potential source have been determined using the calculations contained in Appendix C. For each of the emitted criteria pollutants, the estimated emissions are below threshold levels estab- lished by SJCAPCD for facilities requiring "new source review." This means that emissions are sufficiently low such that environmental impacts would be insignificant, and that additional analyses and emission controls would not be required. The calculated levels of emissions and the corresponding SJCAPCD threshold levels are shown in Table 3.11. In addition to the criteria pollutant emissions presented above, the project would also emit toxic or potentially toxic air contaminants. These pollutants would be contained in the waste oil being treated at the facility and would be emitted from the oil handling and reclamation processes and from the combustion of recycled oil in the dryers. The combustion of distillate fuel oil in the dryers would also contribute to the toxic emissions from the facility. The toxic pollutants which may potentially be emitted from the proposed facility are given below: • Arsenic • Benzene • Benzo (a) pyrene • Beryllium • Cadmium • Chromium (hexavalent) • Dioxins and dibenzofurans • Lead • Nickel 3-63 101-30.R5 4/13/89
