| Regional Board Conclusion: | This pollutant is being considered for placement on the section 303(d) list under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status.
One line of evidence are available in the administrative record to assess this pollutant. Fourteen of the copper samples, exceed the sediment quality guidelines. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against 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. Fourteen of the copper samples, 48 samples exceeded the sediment quality guidelines and this does exceed the allowable frequency listed in Table 3.1 of the Listing Policy. However, it is more appropriate to assess this beneficial use by using the sediment quality objective that the State Board has approved and that is pending EPA approval. At this time, there is not enough data to use the sediment quality objectives and the municipal storm water permit for Orange County will be amended to require additional analytes in the monitoring program that will allow for a complete analyses of the data using the sediment quality objective. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. State Board Review and Comments State Water Board staff, after review, concurs with RWQCB decision against placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category. However, staff does not concur with all the reasons contained in the Regional Board Weight of Evidence. Placement on the section 303(d) list under section 3.1 of the Listing Policy requires data on toxicants in water. One line of evidence for sediment is available in the administrative record to assess this pollutant. Under section 3.6 of the Listing Policy, one line of evidence is required to assess toxicity in sediment. There is insufficient information if the pollutant in sediment is causing sediment toxicity. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against 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. Fourteen of 48 samples exceeded the sediment quality guidelines and this exceeds the allowable frequency listed in Table 3.1 of the Listing Policy. However, there is no evidence that sediment toxicity is present in the water body. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. |
| Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because it cannot be determined if applicable water quality standards are not being exceeded. |

One line of evidence are available in the administrative record to assess this pollutant. Twenty-two samples of the mercury samples exceed the sediment quality guidelines.
