than one additional cancer case would result from the exposure of the population in the greater Stockton area to air emissions from the proposed facility. The estimated maximum individual cancer risk of 3.1 x 10-6 exceeds the SJCAPCD limit of 1.0 x 10-6 (i.e., a one in one million risk of cancer) . Consequently, if the facility is to be granted an Authority to Construct and Permit to Operate, it must demonstrate that the cancer risk can be reduced to 1.0 x 10-6. This can be accomplished by reducing toxic emissions by approximately 68 percent. Alternatively, because the esti- mated risk is less than 5.0 x 10-6 (i .e. , a five in one million risk) , operation would be allowed provided that the facility is equipped with the best available air emission control technology, as defined and approved by the SJCAPCD. Mitigation Measures. The following mitigation measures are proposed by the applicant and were assumed in the Reese-Chambers health risk assessment: (1) hydrocarbon emissions from the waste oil evaporator would be controlled through the use of a condenser/activated charcoal filter system; (2) hydrocarbon emissions from waste oil handling processes would be minimized through the use of vacuum trucks and a vacuum delivery system; (3) emissions from reclaimed oil storage would be minimized using fixed-roof storage tanks; (4) fuel use would be controlled to ensure that combustion emissions from the dryers would remain below federal , State, and SJCAPCD acceptable levels; (5) particu- late emissions from the dryer and from the briquette and pelletizer cool ing operations would be controlled with a cyclone; (6) fugitive dus emissions from the biomass storage pile would be minimized through the use of wind breaks and the application of water; (7) all biomass handling/processing equipment (except the reclaim hopper) would be fully enclosed during operation to minimize fugitive dust emissions; and (8 dust emissions from the classifying bins would be controlled through th use of a cloth filtration system. Finally, to ensure that waste oil containing concentration levels above specific limits is not burned, a waste oil sampling program would be developed and implemented. 3-65 101-30.R5 4/13/89
