Data considered were the sum of PCB congeners (total PCBs), reported as ng/g, wet weight. OEHHA and SWAMP recommend use of total PCBs for evaluating contamination.Total PBCs in 0 of 3 composite samples exceeded 3.6 ng/g. Concentrations were less than the reporting limit (2 ng/g) in 2 composites of rainbow trout and 1.4 ng/g in pikeminnow. Fork lengths of fish samples were greater than 130 mm.

Evaluation Guideline: | The California Office of Environmental Health Hazard Assessment (OEHHA) Fish Contaminant Goal for total PCBs in fish is 3.6 ng/g (3.6 ppb), wet weight, to protect human health. This concentration in fish tissue should not be exceeded, based on a total fish and shellfish consumption rate of 8 ounces (prior to cooking) per week (32 g fish/day) (OEHHA, 2008). This goal incorporates a maximum cancer risk level of one in a million (no more than one additional cancer in a population of one million people consuming these fish). |

Water Quality Objective/Criterion: | At no time or place shall the temperature of COLD or WARM intrastate waters be increased more than 5 degrees F above natural receiving water temperature. To the extent of any conflict with the above, the more stringent objective applies. In determining compliance with the water quality objectives for temperature, appropriate averaging periods may be applied provided that beneficial uses will be fully protected. |

Evaluation Guideline: | The guideline used was from Sullivan et al. (2000) Published Temperature Thresholds-Peer Reviewed Literature which includes reviewed sub-lethal and acute temperature thresholds from a wide range of studies, incorporating information from laboratory-based research, field observations, and risk assessment approaches. This report calculated the Annual Maximum (instantaneous maximum observed during the summer) upper threshold criterion for steelhead trout as 21.0 degrees C. The risk assessment approach used by Sullivan et al. (2000) suggests that an upper threshold for the Annual Maximum of 21.0 degrees C for steelhead will reduce average growth 10% from optimum. |
