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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Eight lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. Note, one of the water sample results were not used in the 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. For the commercial or recreational collection of fish, shellfish, or organisms, zero of 17 total water samples (active sampler), zero of one dissolved water samples (active sampler) and zero of zero water samples (water) exceed the evaluation guideline. For the shellfish harvesting beneficial use, zero of 17 total water samples (active sampler), zero of one dissolved water samples (active sampler) and zero of zero water samples (water) exceed the evaluation guideline. These beneficial uses are fully supported. 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. 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. No samples exceed the evaluation guideline for the municipal and domestic supply or the shellfish harvesting beneficial uses, and these do not exceed 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: | 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. |

State Board Decision Recommendation: | After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |

Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Five lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the marine habitat beneficial use, zero of 14 total water samples (active sampler), zero of one dissolved water samples (active sampler) and zero of two water samples (water) exceed the evaluation guideline. The readily available data and information are insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. 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. 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. No samples exceed the evaluation guideline for the marine habitat beneficial use, and this does not exceed the allowable frequency listed in Table 3.1 of the Listing Policy. 4.

For the marine habitat beneficial use, zero of 14 samples (active sampler, total fraction), and zero of one sample (active sampler, dissolved fraction), and zero of three water samples exceed the evaluation guideline. The readily available data and information are insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. 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. 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. No samples exceed the evaluation guidelines for the marine habitat beneficial use. This does not exceed 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: | 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. |

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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Eight lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. Note, one of the water sample results were not used in the 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. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use, zero of 20 total water samples (active sampler), zero of two dissolved water samples (active sampler) and zero of zero water samples (water) exceed the evaluation guideline. For the shellfish harvesting beneficial use, zero of 20 total water samples (active sampler), zero of two dissolved water samples (active sampler) and zero of zero water samples (water) exceed the evaluation guideline. 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. 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. No samples exceed the evaluation guidelines, and this does not exceed 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: | 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. |

Region 3 |
Pacific Ocean, Monterey Bay (excludes inner three miles nearshore) |
||
Pollutant: | Heptachlor epoxide |
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: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Ten lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use, zero of 15 total water samples (active sampler), zero of two dissolved water samples (active sampler) and one of three water samples (water) exceed the evaluation guideline. For the shellfish harvesting beneficial use, zero of 15 total water samples (active sampler), zero of two dissolved water samples (active sampler) and one of three water samples (water) exceed the evaluation guideline. The readily available data and information are insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. 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. 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. While one of three water samples exceed the evaluation guidelines for both the commercial or recreation collection of fish shellfish, or organisms and the shellfish harvesting beneficial use, no other water samples exceed the evaluation guidelines and this does not exceed 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: | 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. |
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. |

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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Eight lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use, zero of 18 water samples (active sampler) and zero of four water samples (water) exceed the evaluation guideline. For the shellfish harvesting beneficial use, zero of 18 water samples (active sampler) and zero of four water samples (water) exceed the evaluation guideline. 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. 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. No samples exceed the evaluation guidelines and this does not exceed 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: | 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. |

Revision Status | Revised |
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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Five lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the marine habitat beneficial use, zero of 14 samples (active sampler, total fraction), and zero of one sample (active sampler, dissolved fraction), and zero of four water samples exceed the evaluation guideline. The readily available data and information are insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. 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. 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. No samples exceed the evaluation guidelines for the marine habitat beneficial use. This does not exceed 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: | 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. |

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: | Omega Aragonite is being assessed using Listing Policy section 3.11, a situation-specific weight of evidence approach. As additional research is needed to increase confidence that the data assessed reflect waterbody conditions, the LOEs for this pollutant are not used to place waterbodies on the CWA section 303(d) list. Instead, an exceedance of the mean Omega Aragonite threshold of <1.4 will indicate the beneficial use may be potentially threatened and the waterbody will be placed in Category 3 if the number of measured exceedances supports rejection of the null hypothesis as presented in Table 3.2 of the Listing Policy for conventional or other pollutants. Eight lines of evidence are available in the administrative record to assess this pollutant. Four of the 8 samples exceed the Omega Aragonite threshold of <1.4. The number of exceedances does not indicate impairment under Listing Policy section 3.2; however, insufficient information is available to determine if the beneficial use is fully supported for this waterbody-pollutant combination. Beneficial use support will be reassessed in a future cycle, if more data are available. In order to make recommendations to list an ocean segment as impaired or to determine that the beneficial use is fully supported for ocean acidification using Omega Aragonite as an evaluation guideline, further research on the following points is needed to increase confidence that data assessed reflects waterbody conditions. 1. Impact of depth on aragonite saturation state, especially within the 0-200m range. 2. Timing in relation to data collection: Determining the number of days at a certain threshold for pteropod life stages. 3. Understanding natural aragonite saturation state levels in an upwelling state. 4. Seasonal variation and shift in dissolution rates. |
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 the applicable beneficial use support rating. |

Water Quality Objective/Criterion: | The California SWRCB Marine Habitat Beneficial Use is defined as "Uses of water that support marine ecosystems including, but not limited to, preservation or enhancement of marine habitats, vegetation such as kelp, fish, shellfish, or wildlife (e.g., marine mammals, shorebirds)." A beneficial use was chosen as the assessment criteria for ocean acdification as impacts due to Omega Aragonite can be from global and local sources. |
||||
Objective/Criterion Reference: | Marine Habitat (MAR) Beneficial use definition for Regional and Statewide use. The California Water Boards' Annual Performance Report - Fiscal Year 13/14 (CA SWRCB, 2014). | ||||
Evaluation Guideline: | The omega aragonite criterion for the protection of the marine habitat beneficial use is used to determine potential impairment of waterbodies due to ocean acidification; a threshold below 1.4 would indicate potential impairment of a waterbody. The omega aragonite saturation state is calculated by the product of the concentrations of dissolved calcium and carbonate ions divided by their product at equilibrium. Lower levels of omega aragonite are correlated with increased dissolution of pteropods (shell species) and a loss of marine life. In Bednaršek 2019, thresholds between 0.9 and 1.5 were found to indicate severe to mild shell dissolution of pteropods, with potential impairment indicated at approximately 1.2 ± 0.1 (for an overall threshold of 1.3) or below. A study conducted by Oregon State University concluded that the “maximum uncertainty of ±0.2 in the calculation of mean omega aragonite saturation state is required to adequately link changes in ocean chemistry to changes in ecosystem function” (McLaughlin 2015). Thus, the mean aragonite saturation state of 1.4 (1.2 ± 0.2), has been used for the assessment of omega aragonite data. | ||||

Evaluation Guideline: | The omega aragonite criterion for the protection of the marine habitat beneficial use is used to determine potential impairment of waterbodies due to ocean acidification; a threshold below 1.4 would indicate potential impairment of a waterbody. The omega aragonite saturation state is calculated by the product of the concentrations of dissolved calcium and carbonate ions divided by their product at equilibrium. Lower levels of omega aragonite are correlated with increased dissolution of pteropods (shell species) and a loss of marine life. In Bednaršek 2019, thresholds between 0.9 and 1.5 were found to indicate severe to mild shell dissolution of pteropods, with potential impairment indicated at approximately 1.2 ± 0.1 (for an overall threshold of 1.3) or below. A study conducted by Oregon State University concluded that the “maximum uncertainty of ±0.2 in the calculation of mean omega aragonite saturation state is required to adequately link changes in ocean chemistry to changes in ecosystem function” (McLaughlin 2015). Thus, the mean aragonite saturation state of 1.4 (1.2 ± 0.2), has been used for the assessment of omega aragonite data. | ||||

Pollutant: | PAHs (Polycyclic Aromatic Hydrocarbons) |
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: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Ten lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For both the commercial or recreational collection of fish, shellfish, or organisms beneficial use and the shellfish harvesting beneficial use: zero of 20 water samples (active sampler, total fraction), zero of one water samples (active sampler, dissolved fraction) and one of four water samples (total fraction) exceed the evaluation guideline. 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. 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. While one of four water samples exceeded the evaluation guidelines for both the commercial or recreational collection of fish, shellfish, or organisms beneficial use and the shellfish harvesting beneficial use, no other samples exceeded the evaluation guidelines and this does not exceed 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: | 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. |
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. |

DECISION ID |
150778 |
Region 3 |
Pacific Ocean, Monterey Bay (excludes inner three miles nearshore) |
||
Pollutant: | Chlordane |
Final Listing Decision: | List on 303(d) list (TMDL required list) |
Last Listing Cycle's Final Listing Decision: | New Decision |
Revision Status | Revised |
Sources: | No Source Analysis Available |
Expected TMDL Completion Date: | 2037 |
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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Ten lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use, nine of 20 samples (active sampler), one of three samples (water, total) and zero of two samples (water, dissolved) exceed the evaluation guideline. For the shellfish harvesting beneficial use, nine of 20 samples (active sampler), one of three samples (water, total) and zero of two samples (water, dissolved) exceed the evaluation guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the CWA 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. Nine of 20 samples (active sampler) exceed the evaluation guidelines for the commercial or recreational collection of fish, shellfish, or organisms and shellfish harvesting beneficial uses. This 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: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |
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. |

Region 3 |
Pacific Ocean, Monterey Bay (excludes inner three miles nearshore) |
||
Pollutant: | DDT (Dichlorodiphenyltrichloroethane) |
Final Listing Decision: | List on 303(d) list (TMDL required list) |
Last Listing Cycle's Final Listing Decision: | New Decision |
Revision Status | Revised |
Sources: | No Source Analysis Available |
Expected TMDL Completion Date: | 2037 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for placement on the section 303(d) List under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Ten lines of evidence are available in the administrative record to assess this pollutant. Note that this decision combines the pollutant ‘DDT’ and ‘total DDT (sum of 4,4'- and 2,4'- isomers of DDT, DDE, and DDD).’ Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use, three of 20 samples (active sampler, total), zero of one sample (active sampler, dissolved), and two of four samples (water) exceed the evaluation guideline. For the shellfish harvesting beneficial use, three of 20 samples (active sampler, total), zero of one sample (active sampler, dissolved), and two of four samples (water) exceed the evaluation guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the CWA 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. Three of 20 samples (active sampler, total) and two of four water samples exceed the evaluation guidelines for both the commercial or recreational collection of fish, shellfish, or organisms and the shellfish harvesting beneficial uses. This 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: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |
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. |

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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Eight lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use, four of 15 samples (active sampler), two of four samples (water), exceed the evaluation guideline. For the shellfish harvesting beneficial use, four of 15 samples (active sampler), two of four samples (water), exceed the evaluation guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the CWA 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. Four of 15 samples (active sampler) and two of four (water) samples exceed the evaluation guidelines for the commercial or recreational collection of fish, shellfish, or organisms and shellfish harvesting beneficial uses. These exceed 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: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |

Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Ten lines of evidence are available in the administrative record to assess this pollutant. Note that the matrices ‘active sampler’ and ‘water’ represent different sampling methods and will not be added together. Both methods represent a concentration in water. For the commercial or recreational collection of fish, shellfish, or organisms, and the shellfish harvesting beneficial uses, 20 of 20 samples (active sampler, total fraction), zero of two samples (active sampler, dissolved fraction) and four of four samples (water, total) exceed the evaluation guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the CWA 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. 20 of 20 samples (active sampler, total fraction) and four of four samples (water, total) exceed the evaluation guidelines for the commercial or recreational collection of fish, shellfish, or organisms and shellfish harvesting beneficial uses. This 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: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |

DECISION ID |
150789 |
Region 3 |
Pacific Ocean, Monterey Bay (excludes inner three miles nearshore) |
||
Pollutant: | Toxaphene |
Final Listing Decision: | List on 303(d) list (TMDL required list) |
Last Listing Cycle's Final Listing Decision: | New Decision |
Revision Status | Revised |
Sources: | No Source Analysis Available |
Expected TMDL Completion Date: | 2037 |
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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Ten lines of evidence are available in the administrative record to assess this pollutant. Note that the matrix ‘active sampler’ represents a concentration in water. Note that multiple samples were not included in the assessment because the laboratory data reporting limit(s) was above the water quality threshold and therefore the results could not be quantified with the level of certainty required by the Listing Policy Section 6.1.5.5. For the commercial or recreational collection of fish, shellfish, or organisms beneficial use and the shellfish harvesting beneficial use: three of four samples (active sampler, total fraction) and zero of one sample (active sampler, dissolved) exceed the evaluation guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the CWA 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. Three of four samples (active sampler, total fraction) exceed the evaluation guidelines for the commercial or recreational collection of fish, shellfish, or organisms and shellfish harvesting beneficial uses. This 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: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |
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. |
