I. IN" RODUCTION <br /> The California Department of Substances Control has adopted rua lations (R-45-75) <br /> which define criteria for the identification of hazardous wastes. These criteria are codified <br /> in Chapter 30 of Title 22 of the California Code of Regulations. Toxicity to aquatic life, <br /> specifically fish, is one of the criteria used to gauge the hazardous potential of a waste. <br /> An acute 96-hour bioassay is used to determine the LC50 as defined in Section 66261.24 <br /> of these regulations. This 96-hour LC50 value serves as the numerical indicator ofthe <br /> toxicity of a waste to aquatic.life. <br /> This report describes the procedures used and the results obtained for the hazardous waste <br /> aquatic toxicity screening test performed by Block Environmental Services(BES) for <br /> American Environmental Network(Project Id. 4203-P2) <br /> BES is an Environmental Laboratory Accreditation Program certified laboratory(#1812, <br /> expiration date- 10/31/98). <br /> 6£/91 'd 99200£6015 'ON XU dINNOAIIVO N3d 2:91 KI 96-01 -030 <br />
