If more than 10 percent of the oil sinks upon application of the OSCA, the agent will be considered a sinking agent;(h) no dispersant or surface washing agent shall be licensed if it has has an average level of toxicity greater than 10 mg/l as applied (EC50 less than 10 mg/l). The average level of toxicity of these agents shall be determined by the testing methods described in the Guidance Document.Cal. Code Regs. Tit. 14, § 885.6
