A review of the survival data shows that',here was 100% survival in the lab control at the end of the test. This result met the test acceptability criterion of at least 90%survival during the 96 hour exposure period. Representative control fish had a mean standard length of 8.6 mm (range 8.3 to 9.0 mm) and a mean wet weight of 0.0039 grams (range 0.0033 to 0.0048 grams). A review of the survival data for Sample AC19258 shows that there was 100% survival in the 750 mg/I and 250 mg/I test treatments, and 9.5%survival in the 500 mg/1 test treatment at the 96 hour exposure period. The results of this screening assay indicate that the LC50 is greater than 750 mg/I, and that [tie sdnlple should be classified as not hazardous under the CCR Title 26 Section 22 criteria. Test results for sample AC19259 are summarized in Table 3. A review of the survival data for Sample AC19259 shows that there was 10% survival In the 750 mg/I test treatment, 90%survival in the 500 mg/I test treatment, and 100% survival in the 250 mg/I test treatment at the 96 hour exposure Eleriod. The results of this screening assay indicate that the LC50 is greater than 750 mg/I, and that the sample should be classified as not hazardous under the CCR Title 26 Section 22 criteria. Test results for sample AC19260 are su-nmarized in Table 4. A review of the survival data shows that there was 100% survival in the lab control at the end of the test. This result met the test acceptability criterion of at least 90%survival during the 96 hour exposure period. A roviow of the survival data for Sample AC:19260 shows that there Was 100% survival in the 750 mg/I, 500 mg/l, and 250 mg/I test treatments at the 96 hour exposure period. The results of this screening assay indicate that the LC50 s greater than 750 mg/I, and that the sample should be classified as not hazardous under the CCR Title 26 Section 22 criteria.
