| Regional Board Conclusion: | This pollutant is being considered for listing under section 3.6 of the Listing Policy. Under section 3.6 a single line of evidence is necessary to assess listing status. One line of evidence is available in the administrative record to assess this pollutant. This water body experiences toxicity. Based on the readily available data for this water body, the weight of evidence indicates that there is sufficient justification available in favor of adding this water segment-pollutant combination to the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. The data concerning current conditions and supporting the listing decision satisfy the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfy the data quantity requirements of section 6.1.5 of the Policy. 3. Two out of 5 water samples exhibited significant acute toxicity to Ceriodaphnia and growth of Selenastrum was significantly lower than the control in four out of five samples. The number of samples with detected significant water toxicity exceeds the allowable frequency listed in Table 3.1 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. 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. |

| Pollutant: | Benthic Community Effects |
| Final Listing Decision: | Do Not List on 303(d) list (TMDL required list) |
| Last Listing Cycle's Final Listing Decision: | New Decision |
| Revision Status | Revised |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | Benthic community effects are being considered for placement on the CWA section 303(d) List under section 3.9 of the Listing Policy. Under section 3.9, when data show benthic community degradation and there is at least one pollutant impairment that could impact benthic macroinvertebrates, the waterbody is placed on the 303(d) List for benthic community effects. Twenty-six lines of evidence evaluating benthic macroinvertebrate bioassessment data are available in the administrative record to assess this indicator. Twenty-six of twenty-six benthic-macroinvertebrate samples exceed the California Stream Condition Index (CSCI) impairment threshold of 0.79. At least one line of evidence includes sufficient pollutant exceedances to indicate the waterbody is impaired for at least one pollutant. However, there is insufficient data and/or information to determine if at least one pollutant could be impacting benthic macroinvertebrates. Based on the readily available data and information, the evidence indicates that there is sufficient justification against placing Benthic Community Effects in this waterbody segment on the CWA section 303(d) List. Although there is insufficient data and/or information to make a beneficial use support determination, the exceedances of the benthic macroinvertebrate samples indicate beneficial uses may be potentially threatened. 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. Twenty-six of twenty-six benthic macroinvertebrate bioassessment samples had CSCI scores below 0.79. 4. At least one line of evidence includes sufficient pollutant exceedances to indicate the waterbody is impaired for at least one pollutant related to aquatic life; however, data and/or information are insufficient to determine if the pollutant(s) is impacting benthic macroinvertebrates. 5. 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. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| Data Used to Assess Water Quality: | Amweg et al. (2006) interpreted results of toxicity testing and sediment pyrethroid concentrations of seven compounds in three samples from Kirker Creek. Total pyrethroid concentrations at Kirker Creek samples were more than 50% higher than the concentrations detected in other six East Bay area creeks that were studied. The pyrethroid concentrations in Kirker Creek samples ranged from 66.1 to 186.2 ng/g. Also the spring sample contained the highest concentration of any single pyrethroid (deltamethrin) measured reaching the value of 57 ng/g.
The Kirker Creek samples had estimated TUs within the range of 5.67-7.2. Based on this analysis the study concluded that there was good evidence for the role of pyrethroids in the observed toxicity. |

| Evaluation Guideline: | The California Stream Condition Index (CSCI) is a biological scoring tool that helps aquatic resource managers translate complex data about benthic macroinvertebrates found living in a stream into an overall measure of stream health. The CSCI score is calculated by comparing the expected condition with actual (observed) results (Rehn, A.C. et al., 2015). CSCI scores range from 0 (highly degraded) to greater than 1 (equivalent to reference). CSCI scoring of biological condition are as follows (per the scientific paper supporting the development of the CSCI scoring tool): greater than or equal to 0.92 = likely intact condition, 0.91 to 0.80 = possibly altered condition, 0.79 to 0.63 = likely altered condition, less than or equal to 0.62 = very likely altered condition. Sites with scores below 0.79 are considered to have exceeded the water quality objective for the aquatic life beneficial use. | ||||

| Evaluation Guideline: | The California Stream Condition Index (CSCI) is a biological scoring tool that helps aquatic resource managers translate complex data about benthic macroinvertebrates found living in a stream into an overall measure of stream health. The CSCI score is calculated by comparing the expected condition with actual (observed) results (Rehn, A.C. et al., 2015). CSCI scores range from 0 (highly degraded) to greater than 1 (equivalent to reference). CSCI scoring of biological condition are as follows (per the scientific paper supporting the development of the CSCI scoring tool): greater than or equal to 0.92 = likely intact condition, 0.91 to 0.80 = possibly altered condition, 0.79 to 0.63 = likely altered condition, less than or equal to 0.62 = very likely altered condition. Sites with scores below 0.79 are considered to have exceeded the water quality objective for the aquatic life beneficial use. | ||||

| Last Listing Cycle's Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with action other than TMDL)(2016) |
| Revision Status | Original |
| Sources: | A Source Unknown |
| Expected Attainment Date: | 2029 |
| Implementation Action Other than TMDL: | This trash listing will be addressed by implementing the trash control provisions of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries of California through the NPDES MS4 permit applicable to this waterbody. |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | This pollutant is being considered for placement on the section 303(d) list under section 3.11 of the Listing Policy. Under section 3.11, listing may be proposed based on the situation-specific weight of evidence. One line of evidence is available in the administrative record to assess this pollutant. The line of evidence consists of data from field visits/trash surveys conducted according to the Rapid Trash Assessment (RTA) methodology. Based on the readily available trash assessment data for this waterbody, the weight of evidence indicates that there is sufficient justification available in favor of placing this water segment-pollutant combination to the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. Data have been evaluated that supports this decision. 2. The Rapid Trash Assessment methodology results showed that this waterbody had threat to aquatic life parameter scores in the poor category (indicating threat to Wildlife Habitat beneficial uses) at two different locations on two different dates. 3. This waterbody is considered impaired by trash because there were exceedances of the evaluation guideline (poor condition category for the trash assessment metric) in more than one location or on more than one date. 4. The data used satisfy the data quality requirements of section 6.1.4 of the Policy. 5. The data used satisfy the data quantity requirements of section 6.1 of the Policy.
6. This trash listing will be addressed by implementing the trash control provisions of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries of California through the NPDES MS4 permit applicable to this waterbody. |
| Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded. |
| 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 and Information Type: | Occurrence of conditions judged to cause impairment | ||||
| Data Used to Assess Water Quality: | Data results were obtained through application the RTA methodology, developed by the Surface Water Ambient Monitoring Program (SWAMP). The RTA documents the total number and characteristics of pieces of trash per one hundred feet of stream or shoreline. The trash assessment protocol involves picking up and tallying all of the trash items found within the defined boundaries of a site. The tally results for level of trash (relating to REC2) and threat to aquatic life (relating to WILD) assessment parameters were considered for the listing determination. These results are available for field visits/trash surveys conducted in March and July 2003, and February 2004 according to the Rapid Trash Assessment methodology.
This waterbody had threat to aquatic life parameter scores in the poor category (indicating threat to Wildlife Habitat beneficial uses) at two different locations on two different dates. |

| Water Quality Objective/Criterion: | The Basin Plan prohibits discharge of Rubbish, refuse, bark, sawdust, or other solid wastes into surface waters or at any place where they would contact or where they would be eventually transported to surface waters, including flood plain areas.
The Basin Plan has a narrative objective for floating material, Waters shall not contain floating material, including solids, liquids, foams, and scum, in concentrations that cause nuisance or adversely affect beneficial uses. The Basin Plan has a narrative objective for settleable material, Waters shall not contain substances in concentrations that result in the deposition of material that cause nuisance or adversely affect beneficial uses. |

| Objective/Criterion Reference: | Water Quality Control Plan (Basin Plan) - San Francisco Bay Region (Region 2) | ||||
| Evaluation Guideline: | If the RTA Parameter 3 (Threat to Aquatic Life) is in the poor condition category (scores 0-5), then WILD is not supported. This level of trash is a large amount (>50 pieces) of transportable, persistent, buoyant litter that is detrimental to aquatic life. The RTA defines poor condition for this parameter as follows, large amount (>50 pieces) of transportable, persistent, buoyant litter such as: hard or soft plastics, balloons, Styrofoam, cigarette butts; toxic items such as batteries, lighters, or spray cans; large clumps of yard waste or dumped leaf litter; or large amount (>50 pieces) of settleable glass or metal. | ||||

| Revision Status | Original |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.6 of the Listing Policy. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.
Two lines of evidence are available in the administrative record to assess this pollutant. Twenty-two of twenty-two samples exceed the sediment chemistry guideline. Sediment toxicity data are associated with this decision but not available for same time period as sediment chemistry data. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for placing this water segment-pollutant combination on the CWA section 303(d) List. 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. Twenty-two of twenty-two samples exceed the sediment chemistry guideline and this sample size is sufficient to determine beneficial use support, with the power and confidence of the Listing Policy. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. Sediment toxicity data are not available for the same times and locations of the sediment chemistry. Therefore, a listing decision cannot be made because the sediment chemistry data are insufficient on their own. 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. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.6 of the Listing Policy. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.
Two lines of evidence are available in the administrative record to assess this pollutant. Nine of twenty-one samples exceed the sediment chemistry guideline. Sediment toxicity data are associated with this decision but are not available for the same time periods and locations as sediment chemistry data. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for placing this water segment-pollutant combination on the CWA section 303(d) List. 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. Nine of twenty-one samples exceed the sediment chemistry guideline and this sample size is sufficient to determine beneficial use support, with the power and confidence of the Listing Policy. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. Sediment toxicity data are not available for the same times and locations of the sediment chemistry. Therefore, a listing decision cannot be made because the sediment chemistry data are insufficient on their own. 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. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| Revision Status | Original |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.6 of the Listing Policy. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.
One line of evidence is available in the administrative record to assess this pollutant. Zero of fourteen samples exceed the guideline. Sediment toxicity data are not associated with this decision because they are not relevant to this decision because there is insufficient information based on sediment chemistry. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for placing this water segment-pollutant combination on the CWA section 303(d) List. 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. Zero of fourteen samples exceed the guideline and this sample size is insufficient to determine beneficial use support, with the power and confidence of the Listing Policy. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. Sediment toxicity data are not associated with this decision because the sediment chemistry data are insufficient. 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 applicable water quality standards are not being exceeded. |

The 7-day mean temperature (maximum value of the 7-day moving average of the daily mean temperature) of 14.8°C was established as the upper threshold criterion for coho salmon and 17.0°C for steelhead trout. The risk assessment approach used by Sullivan et al. (2000) suggests that temperatures exceeding the above thresholds will cause 10% reduction in average growth compared to optimal conditions. | ||||

| Regional Board Conclusion: | This pollutant is being considered for listing under sections 3.6 of the Listing Policy. Under section 3.6 a single line of evidence is necessary to assess listing status. Three lines of evidence are available in the administrative record to assess this pollutant. This water body experiences sediment toxicity. It has been documented that high concentrations of pyrethroids contribute or are the most likely cause of the toxic effect. Based on the readily available data for this water body, the weight of evidence indicates that there is sufficient justification available in favor of adding this water segment-pollutant combination to the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. The data concerning current conditions and supporting the listing decision satisfy the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfy the data quantity requirements of section 6.1.5 of the Policy. 3. Four sediment samples exhibited significant amphipod toxicity and the benthic community is considered to be degraded. The number of samples with detected significant sediment and water toxicity exceeds the allowable frequency listed in Table 3.1 of the Listing Policy. An additional analysis of toxicity units (TU) indicates that the likely cause of observed sediment toxicity is pyrethroid pesticides. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.
The USEPA final decision was to move this listing to the being addressed by a USEPA approved TMDL portion of the 303(d) list, because the San Francisco Bay Urban Creeks Diazinon TMDL was approved by USEPA on 5/16/07 (USEPA, 2007). |

| Data Used to Assess Water Quality: | Amweg et al. (2006) interpreted results of toxicity testing and sediment pyrethroid concentrations of seven compounds in three samples from Kirker Creek. Total pyrethroid concentrations at Kirker Creek samples were more than 50% higher than the concentrations detected in other six East Bay area creeks that were studied. The pyrethroid concentrations in Kirker Creek samples ranged from 66.1 to 186.2 ng/g. Also the spring sample contained the highest concentration of any single pyrethroid (deltamethrin) measured reaching the value of 57 ng/g.
The Kirker Creek samples had estimated TUs within the range of 5.67-7.2. Based on this analysis the study concluded that there was good evidence for the role of pyrethroids in the observed toxicity. |

| Water Quality Objective/Criterion: | All waters shall be maintained free of toxic substances that are lethal to or that produce other detrimental responses in aquatic organisms.
There shall be no chronic toxicity in ambient waters. Chronic toxicity is a detrimental biological effect on growth rate, reproduction, fertilization success, larval development, population abundance, community composition, or any other relevant measure of the health of an organism, population, or community. |

| Evaluation Guideline: | Pyrethroid concentration data and analysis of toxicity units (TU) were used to determine whether pyrethroids could be linked to the observed toxicity to Hyalella azteca. Amweg et al. (2006) determined that samples with less than 1 TU were nontoxic and those with TU greater than 2 were consistently toxic. | ||||

| Spatial Representation: | Data were collected at sampling locations at the lower part of Kirker Creek. | ||||
| Temporal Representation: | Samples were collected during spring and summer seasons of 2004. The last sampling event (late October 2004) occurred after the first rain of the season to capture the potential effects of dry season pesticide use. | ||||
| Environmental Conditions: | Data are representative of the lower watershed (floodway) with the monitoring site located below predominantly residential and industrial areas. | ||||
