DECISION ID	25721	Region 1
Russian River HU, Middle Russian River HA, Santa Rosa Creek

Pollutant:	Indicator Bacteria
Final Listing Decision:	Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)(2010)
Revision Status	Revised
Reason for Delisting:	Not a true delisting. Delisting due to spatial change or other CalWQA administrative reason
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This is not a true delisting. This water body (Russian River HU, Middle Russian River HA, Santa Rosa Creek) has been split into two water bodies for the current Integrated Report cycle: (1) Russian River HU, Middle Russian River HA, Santa Rosa HSA, mainstem Santa Rosa Creek and (2) Russian River HU, Middle Russian River HA, Santa Rosa HSA, tributaries to Santa Rosa Creek. The data assessed in this decision during the 2010 Integrated Report cycle were collected in both the mainstem of Santa Rosa Creek and tributaries to Santa Rosa Creek. Therefore, these data are now split up according to where they were collected, and are now assessed under one of the two new water bodies listed above. This water body will no longer be used and will be retired after this Integrated Report cycle. For this current Integrated Report cycle, and in the future, please refer to the two new water bodies listed above for data and information pertaining to Santa Rosa Creek and its tributaries.

Regional Board Decision Recommendation:	This is not a true delisting. Data originally included in this decision are now evaluated under either the "Russian River HU, Middle Russian River HA, Santa Rosa HSA, mainstem Santa Rosa Creek" water body or the "Russian River HU, Middle Russian River HA, Santa Rosa HSA, tributaries to Santa Rosa Creek" water body depending on where the data were collected. Please see these two new water bodies for decisions on this pollutant. This water body will be retired next Integrated Report cycle.

State Board Staff 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:

All of the 45 E. coli samples collected from Santa Rosa Creek exceed the fecal coliform objective. E. coli samples were collected while fecal coliform samples were not collected. Since E. coli is one of the group of bacteria that comprise the fecal coliform group, it is logical that if median E. coli concentrations for any 30-day period are greater than 50 MPN / 100 ml, then the median fecal coliform concentrations for any 30-day period are also greater than 50 MPN / 100 ml. Of the 69 E. coli samples collected, 45 median E. coli concentration values were calculated based on a minimum of not less than 5 samples for any 30-day period. Of these 45 median values, all 45 exceed the objective. E. coli median values range from 200 to 2,187 MPN / 100 ml. The samples were collected as part of a joint monitoring effort by the Regional Water Board, the City of Santa Rosa, and the Sonoma County Department of Health Services Environmental Health Division. Data are summarized by the Regional Water Board (NCRWQCB 2008).

Water Quality Objective/Criterion:

Per the Basin Plan (NCRWQCB 2007): The bacteriological quality of waters of the North Coast Region shall not be degraded beyond natural background levels. In no case shall coliform concentrations in waters of the North Coast Region exceed the following: In waters designated for contact recreation (REC-1), the median fecal coliform concentration based on a minimum of not less than five samples for any 30-day period shall not exceed 50 MPN* / 100 ml, nor shall more than 10% of total samples during any 30-day period exceed 400 MPN / 100 ml. *Note: MPN is the most probable number of coliform units.

The samples were analyzed for 95 pesticides, pesticide constituents, isomers, or metabolites. For each of the 95 pesticide analytes, 3 to 5 samples were collected. The samples were collected as part of the Surface Water Ambient Water Monitoring Program (SWAMP). The data are found in the 5-Year Monitoring Report (NCRWQCB 2008).

Data Used to Assess Water Quality:

It is unknown whether any of the 5 phosphorus samples collected in the Santa Rosa Creek Watershed exceed the objective as there is insufficient information available to determine exceedance. Specifically, the samples cannot be compared to the objective because diel samples for dissolved oxygen (DO), pH, and/or chlorophyll-a are not available. Nutrients, such as phosphorus, alone do not impair beneficial uses or cause non-attainment of the objective. Rather, they cause indirect impacts through algal growth and extreme diel patterns for DO and pH, which then impair uses. Waterbody-specific factors such as riparian cover, flow conditions, and stream channel configuration also affect how nutrients are processed within the stream and play a large role in determining whether or not nuisance algal conditions will prevail. For these reasons, comparing a single nutrient value to the biostimulatory objective is not recommended. Instead, nutrient-related indicator parameters, such as diel measurements of DO, pH, and/or chlorophyll-a, should be evaluated to determine attainment of the objective and protection of beneficial uses. When nutrient-related indicator parameters exceed targets, nutrient concentrations will then be analyzed to determine whether phosphorus should be added to a possible listing under the 303(d) List. The sample concentrations range from 0.13 to 0.44 mg/l. The samples were collected as part of the Russian River First Flush sampling event. Data are summarized by Katznelson et al. (2003).

Per the Basin Plan (NCRWQCB 2007): The maximum pH objective is 8.5. The minimum pH objective is 6.5.

Objective/Criterion Reference:

Water Quality Control Plan (Basin Plan) - North Coast Region (Region 1)

Evaluation Guideline:

Guideline Reference:

Spatial Representation:

Samples were collected from one location on Santa Rosa Creek at Olive Park along the Prince Memorial Greenway.

Temporal Representation:

The pH samples were collected during 33 site visits from January 2004 to December 2006. The pH samples were collected as instantaneous measurements and do not represent diurnal conditions.

Environmental Conditions:

There are no known environmental conditions (e.g., seasonality, land use practices, fire events, storms, etc.) that are related to these data.

QAPP Information:

Samples were collected in accordance with the "Community Clean Water Institute Volunteer Water Quality Monitoring Program Sampling and Analysis Methods" (CCWI 2007).

Data Used to Assess Water Quality:

None of the 5 pH samples collected in Santa Rosa Creek exceed the water quality objective. Sample concentrations range from a pH of 6.5 to 7.5. The samples were collected as part of the Russian River First Flush sampling event. Data are summarized by Katznelson et al. (2003).

Temporal Representation:

The samples were collected on November 7, 2002. At each site, 2 or 3 instantaneous grab samples were collected over half hour increments. The data are averaged for each site.

Environmental Conditions:

Samples were collected during the first runoff event of the rainy season.

QAPP Information:

Samples were collected in accordance with the study plan and quality control procedures described by Katznelson et al. (2003).

Water Quality Objective/Criterion:

Basin Plan: pH for Russian River (Table 3.1) shall not be depressed below 6.5 nor raised above 8.5. Changes in normal ambient pH levels shall not exceed 0.2 units in waters with designated marine (MAR) or saline (SAL) beneficial uses nor 0.5 units within the range specified above in fresh waters with designated COLD or WARM beneficial uses.
