Water Quality Objective/Criterion: |
Water Quality Control Plan for the Central Coastal Basin (CCRWQCB 2011): All waters shall be maintained free of toxic substances in concentrations which are toxic to, or which produce detrimental physiological responses in, human, plant, animal, or aquatic life. No individual pesticide or combination of pesticides shall reach concentrations that adversely affect beneficial uses. There shall be no increase in pesticide concentrations found in bottom sediments or aquatic life (Chapter III, Section II.A.2 Objectives for all Inland and Surface Waters, Enclosed Bays and Estuaries). |
Objective/Criterion Reference: |
Water Quality Control Plan for the Central Coastal Basin |
|
Evaluation Guideline: |
The evaluation guideline for diazinon is the median lethal concentration (LC50) of 11 ug/g and is normalized by the percentage of organic carbon in the sediment sample. The LC50 11 ug/g is the geometric mean of LC50 values for diazinon from Ding et al. (2011). |

Evaluation Guideline: |
Sigler et al. (1984) states that turbidities of 25 NTU's or greater caused reduction in juvenile salmonid growth due to interference with their ability to find food. |
Guideline Reference: |
Effects of chronic turbidity on density and growth of steelheads and coho salmon. Transactions of the American Fisheries Society 113:142-150 |
|
Spatial Representation: |
Data for this line of evidence for Orcutt Creek was collected at 2 monitoring sites [ 312ORI-Orcutt Solomon Creek at Highway 1, 312ORC-Orcutt Solomon Creek u/s Santa Maria River] |
Temporal Representation: |
Data was collected over the time period 1/27/2005-12/14/2006. Cooperative Monitoring Program (CMP) staff conduct monitoring for conventional pollutants at all Ag Waiver monitoring sites monthly. CMP staff also conduct water toxicity monitoring quarterly and sediment toxicity monitoring annually (in spring). |
Environmental Conditions: |
Staff is not aware of any special conditions that might effect interpretation of the data. |
QAPP Information: |
All data was collected following the Standard Operating Procedures and Data Quality Objectives outlined in the Cooperative Monitoring Program QAPP, (Clark and Ogle 2006). QA data are included in submission. All data are flagged as appropriate. |

Data Used to Assess Water Quality: |
From new listing proposal: Regional Board staff is proposing that multiple water bodies (including Orcutt Solomon Creek) within the Santa Maria watershed be listed for unionized ammonia. The impairment is evidenced by levels of unionized ammonia greater than the general numeric water quality objective of 0.025 mg/l. The Regional Board assessed CCAMP data and results are as follows for two sites on Orcutt Solomon Creek: 3 of 11 and 5 of 12 data points exceed the criterion.
See CCAMP data for further information (CCAMP, 2004). This constituent was not included in the last (2002) data evaluation because data had not been processed in time to meet the 2002 deadline. |

Data Used to Assess Water Quality: |
Water was sampled at Orcutt Creek (ORC) and in the Santa Maria River (SMA) on four separate occasions (June 2002, September 2002, March 2003, and May 2003) (SWAMP, 2004). Water was toxic at both stations in September 2002 and May 2003 (4 exceedances of 4 measurements). Analysis of chlorpyrifos in water showed that on all occasions when water toxicity was observed, concentrations of chlorpyrifos exceeded the LC 50 for this pesticide for toxicity to Ceriodaphnia dubia. Toxicity Identification Evaluations of water samples from Orcutt Creek and the Santa Maria River showed toxicity to C. dubia was due to chlorpyrifos. At the station on Orcutt Creek, 2 of 2 samples were in exceedance of the aquatic life criteria. |

Water Quality Objective/Criterion: |
General WQOs: All waters shall be maintained free of toxic substances in concentrations which are toxic to, or which produce detrimental physiological responses in, human, plant, animal, or aquatic life. Compliance with the objective will be determined by use of indicator organisms, analyses of species diversity, population density, growth anomalies, toxicity bioassays of appropriate duration, or other appropriate methods.
No individual pesticide or combination of pesticides shall reach concentrations that adversely affect beneficial uses. There shall be no increase in pesticide concentrations found in bottom sediments or aquatic life. |

Data Used to Assess Water Quality: |
Water Board staff assessed TMDL Project data for Orcutt Creek to determine beneficial use support and results are as follows: 3 of 3 samples exceed the criterion for Chlorpyrifos. Nine additional samples (quantified as either non-detect or detected but not quantified) were not used in this assessment because the laboratory data reporting limit(s) was above the objective and therefore the results could not be quantified with the level of certainty required by the Listing Policy. An arithmetic mean is calculated when replicates, such as field duplicates, are reported. If a non-detect is one of the results, then one half the reporting limit is used in this calculation. |

Evaluation Guideline: |
Toxicity was defined as a statistically significant effect in the sample exposure compared to the control using EPA-recommended hypothesis testing. The t-test is used to determine if there is a statistically significant decrease in organism response in the sample as compared to the control. In the SWAMP data format, a Significance Effect Code of SL denotes toxic test results. |

Data Used to Assess Water Quality: |
Sediment was sampled at Orcutt Creek (ORC) and in the Santa Maria River (SMA) on two separate occasions (June 2002 and May 2003). Sediment was toxic at both stations in both samples (SWAMP, 2004). Analysis of chlorpyrifos in sediment porewater showed that on all occasions when water toxicity was observed, concentrations of chlorpyrifos exceeded the LC50 for this pesticide to the amphipod Hyalella azteca. Toxicity Identification Evaluations of sediment samples from Orcutt Creek and the Santa Maria River showed toxicity was due to a combination of chlorpyrifos and other pesticides, likely pyrethroid pesticides (refer to attached excel spreadsheet file). Sediment bulk-phase chemical analyses showed elevated concentrations of chlorpyrifos. |

Water Quality Objective/Criterion: |
General WQOs: All waters shall be maintained free of toxic substances in concentrations which are toxic to, or which produce detrimental physiological responses in, human, plant, animal, or aquatic life. Compliance with the objective will be determined by use of indicator organisms, analyses of species diversity, population density, growth anomalies, toxicity bioassays of appropriate duration, or other appropriate methods.
No individual pesticide or combination of pesticides shall reach concentrations that adversely affect beneficial uses. There shall be no increase in pesticide concentrations found in bottom sediments or aquatic life. |

TOXICITY TESTING |
Data Used to Assess Water Quality: |
Three samples were collected to evaluate water toxicity on June 27, 2007 from three different Orcutt Creek sites. One sample exhibited significant toxicity to the invertebrate test organism, Hyalella azteca. The toxicity tests included total cell count of Selenastrum capricornutum, survival and growth of Hyalella azteca, and survival and biomass of Pimephales promelas. One sample can have multiple toxicity test results but will be counted only once. One sample is defined as being collected on the same day at the same location. The SWAMP program has provided guidance (July 2013) defining the range of conductivities that are acceptable for each test organism, the concentration at which alternate test species and or high salinity controls should be used. The samples from 312GVT and 312ORB did show significant toxicity to S. capricornutum however, the conductivity of these sample was greater than 3000 uS/cm, the threshold at which the test should be forgone (SWAMP July 2013). These two sample results will not be counted as exceedances. The sample from 312ORC resulted in significant toxicity to H. azteca (which is the alternate test species for the invertebrate test organism used when conductivity of the sample is greater than 2500 uS/cm). The sample from 32ORC also had significant toxicity to S. capricornutum cell growth. However, the significant effects reported for the S. capricornutum test for the 312ORC sample were not calculated using a high salinity control as specified in the SWAMP memo (July 2013). This sample will be counted as an exceedance because of the toxicity effects to H. azteca. Because the conductivity of the sample water is greater than 1500 uS/cm and the high salinity control was not used to determine toxic effects to S. capricornutum, these results are not counted as exceedances. |
