The discharge of most boilers contain tugh minerals concentrations and heavy metal salts. Some of the contaminates are unlawful to discharge to the surface under Code of Federal Regulations (CFR) 40 and Tine 22 of the Ca€sfornia Admuus=tion Code (GAC). Because of the physical evidence identified during the site inspection in early January 1990, water and soil samples were collected for analysis under criteria established in EPA sampling method 500 (p series) and analyzed in compliance with Tale 22 standards for pnonty pollutant metals and T.T L.C. CAM metals. The completed analysis of both water and soil samples collected from the outfall area indicates that the maximum concentrate levels bm = b= exceeded for the analytes reported by the methods employed (Appendix B). ' Compressor Cmtdeassfe Slowdown Area (Undmrbed Sample) ' Located to the east side of the structure adjacent to the 1,000 KVA power sub- station is the area were the Gardner-Denver air compressor is mstalled (Figure 3) The compressor's condensate blowdown lune discharges to the surface. Ms too is ' considered to be an unlawful discharge to the surface. Compressor discharge usually contain heavy metals from the oil it pumps and the body of the pump itself. ' A single soil sample was collected and subriutted to the laboratory for the same metals analysis as discussed to the flood control outfall segment of thus report. All ' analytes detected were well beloR the maximum concentration levels established by Tide 22 of CAC (Appendix B). Pesticides Usage (Grab Sample) ' Durnng the site inspection conducted in early January 1990 a concern about pesticide usage at this facility was noted on the writers part.
