Each OSCA to be considered for licensing by the Administrator shall comply with the following efficacy and toxicity criteria:
(a) the OSCA must have a flash point of 170 degrees Fahrenheit or greater;(b) the hydrogen ion activity of a liquid OSCA that is water soluble, as applied to the water surface must be 6.5 to 8.5 pH units;(c) the heavy metal and chlorinated hydrogen content must not be greater than the following concentration(s) in parts per million or milligrams per liter of product: (1) Mercury - 0.005, Cadmium - 0.01, Lead - 0.05,(2) total identifiable chlorinated hydrocarbon - 0.05.(d) the OSCA must perform as indicated by the manufacturer when applied in the manner recommended by the manufacturer;(e) bioremediation agents must degrade the oil through microbial action, and neither the bioremediant or its by-products may be more toxic in the aquatic environment than the oil on which applied;(f) collecting agents must be nontoxic, and upon application to an oil spill, at least 90 percent of the oil-agent mass must remain afloat;(g) dispersant efficacy must be established in accordance with the standardized efficacy tests required by this subchapter, and found in the Guidance Document. 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
