| Regional Board Conclusion: | Regional Water Board Conclusion:
This pollutant was considered for placement on the section 303(d) List in a previous Integrated Report cycle. No new information was reviewed for this current Integrated Report cycle. Therefore, the previous conclusion remains unchanged, and is as follows: 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. 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 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 region was not assessed this cycle. All decisions have been carried over from the previous cycle and remain the same. |
| 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: | Information submitted for identifying potential sediment impairment in Big Salmon Creek in the form of a NCRWQCB memorandum from Cherie Blatt to Bruce Gwynne (June 2004) which includes: Initial Study Negative Declaration for CEQA review (Permit No. 1600-2002-0765-3) from Campbell Timberland Management L.L.C.; parts of Timberland Harvesting Plan (THP) 1-04-061 SON comprised of results of hill-slope hazard analysis, stream condition tables (2), and stream inventory report; habitat inventory report; THP 1-02-014 MEN; letters (2 ea.) of additional information for THP 1-93-394 MEN; interoffice communication (2 ea.) within the NCRWQCB; A 1993 Department of Forestry and Fire Protection interoffice field memorandum and; a memorandum stating the RWQCB authority under water code section 13267(b) on Timber Harvest Lands. Most of the information demonstrates that there is a salmonid habitat issue in the water body. Potential cause to habitat degradation has been attributed to the lack of adequate large woody debris in the channel and sedimentation Even though the information submitted does not contain substantial information for listing, it does contain enough evidence to warrant further investigation of habitat degradation in the water body. | ||||

| Regional Board Conclusion: | Regional Water Board Conclusion:
This pollutant was considered for placement on the section 303(d) List in a previous Integrated Report cycle. No new information was reviewed for this current Integrated Report cycle. Therefore, the previous conclusion remains unchanged, and is as follows: This pollutant is being considered for placement on the Section 303(d) List under Section 3.2 of the Listing Policy. Under Section 3.2 a single line of evidence is necessary to assess listing status. One line of evidence is available in the administrative record to assess temperature consistent with Listing Policy section 6.1.5.9. Data was collected instream from 8 sampling locations along Big Salmon Creek. These locations were distributed along the mainstem of Big Salmon Creek, along Hazel Creek, and Donnelly Gulch. When compared to the 14.8 °C threshold, there were 248 exceedances out of 5,205 samples taken over all of the sampling years. When compared to the 17°C threshold there were no exceedances found for any of the data. 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. There were 238 of 5,205 samples that exceeded the 14.8°C temperature evaluation guideline and this does not exceed the allowable frequency calculated from the equation in Table 3.2 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. |
| Regional Board Decision Recommendation: | This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current cycle. The decision has not changed. |

| Data Used to Assess Water Quality: | When the data was compared to the 14.8 °C coho threshold, there were 238 exceedances out of 5,205 samples taken over all of the sampling years at the locations on Salmon Creek. When compared to the 17°C threshold there were no exceedances found for any of the data. (Hawthorne Timber Co., 2003) | ||||

| Water Quality Objective/Criterion: | Basin Plan: Temperature objectives for COLD interstate waters, WARM interstate waters, and Enclosed Bays and Estuaries are as specified in the "Water Quality Control Plan for Control of Temperature in the Coastal and Interstate Waters and Enclosed Bays of California" including any revisions thereto. A copy of this plan is included verbatim in the Appendix Section of this Plan. In addition, the following temperature objectives apply to surface waters: The natural receiving water temperature of intrastate waters shall not be altered unless it can be demonstrated to the satisfaction of the Regional Water Board that such alteration in temperature does not adversely affect beneficial uses. At no time or place shall the temperature of any COLD water be increased by more than 5°F above natural receiving water temperature. At no time or place shall the temperature of WARM intrastate waters be increased more than 5°F above natural receiving water temperature. | ||||

| 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 7-day Mean (maximum value of the 7-day moving average of the daily mean temperature) upper threshold criterion for coho salmon as 14.8°C and for steelhead trout as 17.0°C. The risk assessment approach used by Sullivan et al. (2000) suggests that an upper threshold for the for the 7-day average of 14.8°C for coho and 17.0°C for steelhead will reduce average growth 10% from optimum. | ||||

| Spatial Representation: | Data was collected instream from 8 sampling locations along Big Salmon Creek. These location were distributed along the mainstem of Big Salmon Creek, along Hazel Creek, and Donnelly Gulch. Hobo-Temps were placed in the pools near the bottom and towards the deepest portion to record the in-stream temperatures. In stream and riparian measurements were taken at all monitoring locations. | ||||
| Temporal Representation: | Data was recorded for 10 years from 1994 through 2003. Water temperature data were recorded at ninety-minute intervals, generally from June until Mid-October
Stream temperatures were measured continuously with temperature data loggers (Onset Computer Corp. model HOBO-Temp and OST temperature loggers) in Class 1 streams throughout the property from 1994 to 2004. Hobo-temps allowed uninterrupted data collection to occur throughout the critical summer period. |

| QAPP Information: | QA/QC Information Summary was submitted. Installation of the temperature data logger (Onset Computer Corp. model HOBO-Temp and OST temperature loggers in Class 1 streams throughout the property devices occurred one day before the first day logged on the continuous temperature monitoring figures. This was done to allow the data loggers to reach equilibrium with the instream temperature regimes and to capture complete daily cycles. No information on equipment calibration, standard operating procedures or data protocols were included with the submittal. | ||||
