TMDL Project Code: | 396 |
Date TMDL Approved by USEPA: | 12/22/2005 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and section 4.6 of the Listing Policy. Under SECTION of the Policy, a minimum of one line of evidence is needed to assess listing status. Five lines of evidence are available in the administrative record to assess this pollutant. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 0 of 0, 0 of 4, 0 of 4, 0 of 3 and 0 of 3 samples exceeded the guideline for cadmium in sediment and this is insufficient to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. A minimum of 28 samples is required for delisting. 4. The Ballona Creek Metals TMDL has been approved by the Regional Board in 7/2005 and by USEPA in 12/2005. 5. Pursuant to section 4.11 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 removed from the section 303(d) list because there was a previous listing and there are not enough data to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. |

Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for delisting under sections 4.1 of the Listing Policy. Under section 4.1 a single line of evidence is necessary to assess listing status. 11 lines of evidence are available in the administrative record to assess this pollutant. Based on the readily available information, the weight of evidence indicates that there is sufficient justification in favor of placing this water segment-pollutant combination in the Water Quality Limited Segments Being Addressed portion of 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. 20 of 23 samples exceeded the effects range median listed in the evaluation guideline for chlordane in sediment and this sample size and this exceeds the allowable frequency listed in Table 4.1 for estuarine habitat. There is an associated sediment toxicity data as required by Section 4.6 of the Listing Policy. 8 of 9 samples exhibited sediment toxicity. 4. 2 of 3 samples exceeded the effects range median listed in the evaluation guideline for chlordane in sediment and this sample size and this exceeds the allowable frequency listed in Table 4.1 for marine habitat. There is an associated sediment toxicity data as required by Section 4.6 of the Listing Policy. 8 of 9 samples exhibited sediment toxicity. 5. 0 of 4 samples exceeded the screening values listed in evaluation guideline for chlordane in tissue and this does not exceeds the allowable frequency listed in Table 3.1 for estuarine habitat. 6. The Ballona Creek Toxic Sediments TMDL has been approved by the Regional Board in July 2005 and by USEPA in December 2005 and is in place to address this pollutant in this water body. 7. Pursuant to section 4.11 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 removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded. |

Last Listing Cycle's Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL)(2018) |
Revision Status | Revised |
Sources: | A Source Unknown |
TMDL Name: | Ballona Creek Metals (57) |
TMDL Project Code: | 396 |
Date TMDL Approved by USEPA: | 12/22/2005 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and 4.1 and 4.6 of the Listing Policy. 8 lines of evidence are available in the administrative record to assess this pollutant. 14 of 56 samples exceeded the criteria for copper in water. 4 of 8 samples exceeded the criteria for copper in water. 5 of 6 samples exceeded the criteria for copper in water. 5 of 6 samples exceeded the criteria for copper in water. 0 of 4 samples exceeded the guideline for copper in sediment. 0 of 4 samples exceeded the guideline for copper in sediment. 0 of 3 samples exceeded the guideline for copper in sediment. 0 of 3 samples exceeded the guideline for copper in sediment. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 14 of 56, 4 of 8, 5 of 6 and 5 of 6 samples exceeded the criteria for copper in water and these exceed the allowable frequency listed in Table 4.1 of the Listing Policy. 4. The TMDL for Metals in Ballona Creek was approved by USEPA on 12/22/2005. 5. Pursuant to section 4.11 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 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. |

Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and 4.3 of the Listing Policy. Under section 4.3of the Policy, a minimum of one line of evidence is needed to assess listing status. Two lines of evidence are available in the administrative record to assess this pollutant. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 24 of 26 samples exceeded the geometric mean and 17 of 45 samples exceeded the statistical threshold value for Enterococcus and these exceed the allowable frequency listed in Table 4.3 of the Listing Policy. 4. The Ballona Creek, Ballona Estuary and Sepulveda Channel Bacteria TMDL was approved by USEPA on March 26, 2007 5. Pursuant to section 4.11 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 removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded. |

Ballona Creek Estuary |

Pollutant: | PAHs (Polycyclic Aromatic Hydrocarbons) |
Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL) |
Last Listing Cycle's Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL)(2018) |
Revision Status | Revised |
Sources: | Nonpoint Source | Point Source |
TMDL Name: | Ballona Creek Toxics (55) |
TMDL Project Code: | 235 |
Date TMDL Approved by USEPA: | 12/22/2005 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and section 4.6 of the Listing Policy. Under SECTION of the Policy, a minimum of one line of evidence is needed to assess listing status. Five lines of evidence are available in the administrative record to assess this pollutant. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 0 of 9, 0 of 9, 0 of 3 and 0 of 3 samples exceeded the guideline for PAHs in sediment and this is insufficient to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. A minimum of 28 samples is required for delisting. 4. The Ballona Creek Metals TMDL has been approved by the Regional Board in 7/2005 and by USEPA in 12/2005. 5. Pursuant to section 4.11 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 removed from the section 303(d) list because there was a previous listing and there are not enough data to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. |
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 4 |
Ballona Creek Estuary |

Pollutant: | PCBs (Polychlorinated biphenyls) |
Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL) |
Last Listing Cycle's Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL)(2018) |
Revision Status | Revised |
Sources: | Nonpoint Source | Point Source |
TMDL Name: | Ballona Creek Toxics (55) |
TMDL Project Code: | 235 |
Date TMDL Approved by USEPA: | 12/22/2005 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for delisting under sections 4.1 of the Listing Policy. Under section 4.1 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. Based on the readily available information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the Water Quality Limited Segments Being Addressed portion of 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. Four out of 4 tissue samples exceed the OEHHA screening value and this exceeds the number allowed by the Listing Policy. Although sediment toxicity has been observed, 0 of 3, 0 of 3, and 1 of 28 samples exceed the guideline for pollutants in sediment. The Ballona Creek Toxics TMDL was approved by RWQCB in July 2005 and subsequently approved by USEPA in December 2005 and is in place to address this pollutant in this water body. 4. Pursuant to section 4.11 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 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. |

Region 4 |
Ballona Creek Estuary |

Pollutant: | Silver |
Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL) |
Last Listing Cycle's Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL)(2018) |
Revision Status | Revised |
Sources: | A Source Unknown |
TMDL Name: | Ballona Creek Toxics (55) |
TMDL Project Code: | 235 |
Date TMDL Approved by USEPA: | 12/22/2005 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and 4.1 and 4.6 of the Listing Policy. Ten lines of evidence are available in the administrative record to assess this pollutant. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 0 of 1, 0 of 1, 0 of 6 and 0 of 6 samples exceed the criteria for silver in water and 0 of 4, 0 of 4, 0 of 3 and 0 of 3 samples exceeded the guideline for silver in sediment and this is insufficient to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy 4. The TMDL for Metals in Ballona Creek was approved by USEPA on 12/22/2005. 5. Pursuant to section 4.11 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 removed from the section 303(d) list because there was a previous listing and there are not enough data to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. |
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: | Zinc |
Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL) |
Last Listing Cycle's Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL)(2018) |
Revision Status | Revised |
Sources: | Nonpoint Source | Point Source |
TMDL Name: | Ballona Creek Metals (57) |
TMDL Project Code: | 396 |
Date TMDL Approved by USEPA: | 12/22/2005 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for delisting under sections 4.1 and 4.6 of the Listing Policy. Under section 4.1 a single line of evidence is necessary to assess listing status. Two lines of evidence are available in the administrative record to assess this pollutant. 10 lines of evidence are available in the administrative record to assess this pollutant. 0 of 6 samples exceeded the criteria for zinc in water. 0 of 6 samples exceeded the criteria for zinc in water. 2 of 3 samples exceeded the criteria for zinc in water. 2 of 3 samples exceeded the criteria for zinc in water. 3 of 28 samples exceeded the guideline for zinc in sediment. 0 of 4 samples exceeded the guideline for zinc in sediment. 0 of 4 samples exceeded the guideline for zinc in sediment. 0 of 3 samples exceeded the guideline for zinc in sediment. 0 of 3 samples exceeded the guideline for zinc in sediment. 4 of 5 samples exhibited sediment toxicity. 4 of 4 samples exhibited sediment toxicity. Based on the readily available information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the Water Quality Limited Segments Being Addressed portion of 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. Two of three and 2 of three samples exceeded the criteria for zinc in water and 3 of 28 samples exceeded the guideline for zinc in sediment and this does not exceed the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity. 4. The TMDL for Metals in Ballona Creek was approved by the USEPA on 12/22/2005 5. Pursuant to section 4.11 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 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. |

Revision Status | Revised |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | Insufficient information is available to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. Beneficial use support will be reassessed in a future cycle, if more data are available. |
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 | Revised |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | Insufficient information is available to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. Beneficial use support will be reassessed in a future cycle, if more data are available |
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 | Revised |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | Insufficient information is available to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. Beneficial use support will be reassessed in a future cycle, if more data are available. |
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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of 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. 2 of 2 samples exceed the CRITERIA and 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. |

Regional Board Conclusion: | This pollutant is being considered for removal from the section 303(d) list under section 4.1 of the Listing Policy. Under section 4.1 a single line of evidence is necessary to assess delisting status.
Two lines of evidence is available in the administrative record to assess toxicity. Based on the readily available information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the Water Quality Limited Segments Being Addressed portion of 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. Eight of nine samples exhibit significant toxicity to Eohaustorius Estuarius and this sample size is insufficient to determine with the power and confidence of the Listing Policy if standards are met. 4. The Ballona Creek Toxics TMDL was approved by RWQCB in July 2005 and subsequently approved by USEPA and is in place to address toxicity in this water body. 5. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met. |
