| Impairment from Pollutant or Pollution: |
Pollutant |
| |
| Weight of Evidence: |
This pollutant is being considered for placement on the section 303(d) list under section 3.5 of the Listing Policy. One line of evidence is available in the administrative record to assess this pollutant.
Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category.
This conclusion is based on the staff findings that:
1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy.
2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy.
3. Seven out of 9 samples exceeded the OEHHA Screening Value and this exceeds the allowable frequency listed in Table 3.1 of the Listing Policy.
4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. |

| RWQCB Board Decision / Staff Recommendation: |
No new data were assessed for 2008. The decision has not changed. |
| |
| SWRCB Board Decision / Staff Recommendation: |
After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |

| Data and Information Type: |
Not Specified |
| Data Used to Assess Water Quality: |
Seven out of 9 samples exceeded. A total of 9 composite samples were collected and analyzed from Anderson Reservoir: 3 black crappie, 3 carp, and 3 largemouth bass. Two black crappie samples did not exceed (TSMP, 2002). |

| Water Quality Objective/Criterion: |
San Francisco Bay RWQCB Basin Plan: Many pollutants can accumulate on particles, in sediment, or bioaccumulate in fish and other aquatic organisms. Controllable water quality factors shall not cause a detrimental increase in concentrations of toxic substances found in bottom sediments or aquatic life. Effects on aquatic organisms, wildlife, and human health will be considered. |
