| Pollutant: | Sediment |
| Final Listing Decision: | Do Not List on 303(d) list (TMDL required list) |
| Last Listing Cycle's Final Listing Decision: | Do Not List on 303(d) list (TMDL required list)(2006) |
| Revision Status | Original |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | This pollutant is being considered for placement on the section 303(d) list under section 3 of the Listing Policy. Under section 3 a single line of evidence is necessary to assess listing status.
Based on the readily available data and information, the weight of evidence indicates that there is insufficient 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 documents submitted do not contain substantial information for listing, more data is needed to determine if the water quality objective is exceeded. 2. 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: | This is a decision made by the State Water Resources Control Board and approved by the USEPA in 2006 . No new data were assessed by the Regional Board for 2008. The decision has not changed. |
| State Board Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |

| Data Used to Assess Water Quality: | The reports and plans were submitted for potential sedimentation impairments include: Winchuck River Watershed Action Plan, Curry Action Plan, and Winchuck River Watershed Assessment. Most of information in these documents contain historical documentation of degradation of the watershed, narrative evaluation of roads, crossing, and watercourses within these areas while conducting preharvest inspections for proposed timber harvest plans. Also, Coho has been listed as Threatened, according to the Endangered Species Act, since May of 1997. Even though the information submitted does not contain substantial information for listing, there does appears to be enough evidence that warrants further investigation of habitat degradation in watershed (Maguire, 2001; Massingill, 2001; Massingill, 2002). | ||||
