| Weight of Evidence: |
This pollutant is being considered for removal from the section 303(d) list under section 4 of the Listing Policy. The Policy calls for the delisting of waters if the decision is found to be based faulty data and it is demonstrated that the listing would not have occurred in the absence of such faulty data. One line of evidence is available in the administrative record to assess this pollutant.
The original listing was based on visual observations. No data was used to list this pollutant.
Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for maintaining the listing for this water segment-pollutant combination.
This conclusion is based on the staff findings that no data is available to assess the status of this water body for this pollutant. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are 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 removed from the section 303(d) list because no data are available to support the listing. |

| Data Used to Assess Water Quality: |
Original listing was based on Regional Board staff visual observations of erosion. No data or QA/QC information available.
The basis for this listing basis is faulty because no data are available to support the listing. Regional Board staff is not aware of evidence to indicate current water quality standards exceedances or beneficial use impacts related to the listing for this pollutant. |
