TMDL Project Code:	416
Date TMDL Approved by USEPA:	03/23/2012
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, 4.1 and 4.6 of the Listing Policy. Four 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. 8 of 12 samples exceeded the guideline for benzo(a)athracene in sediment and these exceed the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity, with 3 of 7 sediment samples exhibiting toxicity. 4. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012. 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.

TMDL Project Code:	416
Date TMDL Approved by USEPA:	03/23/2012
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 4.6 of the Listing Policy. Three 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. 9 of 12 and 2 of 2 samples exceeded the guideline for chrysene in sediment and these exceed the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity, with 3 of 7 sediment samples exhibiting toxicity. 4. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012. 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.

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 and 0 of 0 sample exceeded the criteria for DDT in water and 0 of 0 sample exceeded the guideline for DDT 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 needed to determine if a beneficial use is fully supported using table 4.1. 4. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012. 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.

Regional Board Conclusion:	This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and 4.6 of the Listing Policy. Four 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. 4 of 12 and 2 of 2 samples exceeded the guideline for dibenz[a,h]anthracene in sediment and these exceed the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity, with 3 of 7 sediment samples exhibiting toxicity. 4. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012. 5. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

DECISION ID	149640	Region 4
Los Angeles - Harbor Fish Harbor

Pollutant:	Mercury
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:	Dominguez, LA/LB Harbors, San Pedro Bay Metals (75 & 78), toxics(73a) and PAHs (74)
TMDL Project Code:	416
Date TMDL Approved by USEPA:	03/23/2012
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. Under 4.1 of the Policy, a minimum of one line of evidence is needed to assess listing status. Seven lines of evidence are available in the administrative record to assess this pollutant. 0 of 6 samples exceed the criteria. 0 of 7 samples exceed the criteria. 0 of 8 samples exceed the criteria. 7 of 10 samples exceed the guideline. 2 of 2 samples exceed the guideline. 3 of 7 samples exhibit sediment toxicity. 0 of 1 samples exhibit sediment toxicity. 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 6, 0 of 7 and 0 of 8 samples exceeded the criteria for mercury in water and this sample size is insufficient to determine beneficial use support, with the power and confidence of the Listing Policy. 7 of 10 and 2 of 2 samples exceeded the guideline for mercury in sediment and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity. 4. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012. 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 delisting under sections 4.6 of the Listing Policy. Under section 4.6 two lines of evidence are 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 not removing this water segment-pollutant combination from the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. The sediment quality guideline used complies with the requirements of section 6.1.3 of the Policy. 2. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 3. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 4. 11 of 12 and 6 of 12 samples exceeded the guideline and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. Sediment toxicity is also observed in 3 of 7 and 0 of 1 samples. 5.Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met There is sufficient justification to place this waterbody/pollutant in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by USEPA, and is expected to result in attainment of the standard. This conclusion is based on the staff findings that: 1. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012.

Final Listing Decision:	Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL)
Last Listing Cycle's Final Listing Decision:	Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL)(2018)
Revision Status	Revised
Sources:	A Source Unknown
TMDL Name:	Dominguez, LA/LB Harbors, San Pedro Bay Metals (75 & 78), toxics(73a) and PAHs (74)
TMDL Project Code:	416
Date TMDL Approved by USEPA:	03/23/2012
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, 4.1 and 4.6 of the Listing Policy. Seven 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. 6 of 13 samples exceeded the guideline for PCBs in sediment and these exceed the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity, with 3 of 7 and 0 of 1 sediment samples exhibiting toxicity. 4. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012. 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.

Sediment toxicity is observed and a sufficient number of samples exceeded the sediment quality guideline. Under section 3.6 documented pollutant exceedances in sediment must be associated with observed toxicity before listing can occur. 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 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. Six of 12 samples and 0 of 2 samples exceeded the Phenanthrene sediment quality guideline and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. There is an associated sediment toxicity, with 3 of 7 and 0 of 1 samples exhibiting toxicity. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are met. There is sufficient justification to place this waterbody/pollutant in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by USEPA, and is expected to result in attainment of the standard. This conclusion is based on the staff findings that: 1. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012.

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.

Two lines of evidence are available in the administrative record to assess this pollutant. 3 of 7 samples exhibit sediment toxicity. 0 of 1 sample exhibits sediment toxicity. 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 on the 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.

DECISION ID	136049	Region 4
Los Angeles - Harbor Fish Harbor

Pollutant:	2-Methylnaphthalene
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(2018)
Revision Status	Revised
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the section 303(d) list under section 3.6 of the Listing Policy. Under section 3.6 two lines of evidence are necessary to assess listing status. Three lines of evidence are available in the administrative record to assess this pollutant. Although sediment toxicity was observed, an insufficient number of samples exceeded the sediment quality guideline. Under section 3.6 documented pollutant exceedances in sediment must be associated with observed toxicity before listing can occur. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification in favor of placing this water segment-pollutant combination on the 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. One of 9 and 0 of 2 samples exceed the guideline for 2-methylnaphthalene in sediment and this does not exceed the allowable frequency listed in Table 3.1 of the Listing Policy. Section 3.6 of the Listing Policy requires that the pollutant concentration in sediment be linked to observed toxicity before placing a water segment on the 303(d) list. Evidence of observed toxicity helps establish a connection between the pollutant in the sediment and toxicity impacts to the aquatic habitat in the water body segment. 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.

TMDL Project Code:	416
Date TMDL Approved by USEPA:	03/23/2012
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is also being considered for placement on the CWA section 303(d) List under sections 3.1 of the Listing Policy. Under section 3.1 at least one line of evidence is necessary to assess listing status. 1 line of evidence is available in the administrative record to assess this pollutant. 2 of 2 sample exceeded the criteria. 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 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. 2 of 2 samples exceeded 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 met There is sufficient justification to place this waterbody/pollutant in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by USEPA, and is expected to result in attainment of the standard. This conclusion is based on the staff findings that: 1. The Dominguez Channel and Los Angeles and Long Beach Harbors Toxics and Metals TMDL was approved by USEPA on 03/23/2012.

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.

DECISION ID	72174	Region 4
Los Angeles - Harbor Fish Harbor

Pollutant:	Benthic Community Effects
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(2016)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the section 303(d) list under section 3.9 of the Listing Policy. Under section 3.9 a water segment can be placed on the 303(d) list if the water segment exhibits significant degradation in biological populations and/or communities as compared to reference sites and is associated with water or sediment pollutant concentrations. One line of evidence is available in the administrative record to assess this pollutant. No bioassessment measurement was considered degraded. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification in favor of placing this water segment-pollutant combination on the 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.One of 5 samples taken exhibited significant degradation and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating.

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 cycle. The decision has not changed.

Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(2016)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the section 303(d) list under section 3.6 of the Listing Policy. Under section 3.6 At least two lines of evidence are necessary to assess listing status. One line of evidence documents the presence of the pollutant. The other line of evidence documents non-significant sediment toxicity. Both lines of evidence must establish a connection between the water or sediment concentrations of pollutant(s) and toxicity. In this case, there is no sediment guideline for this pollutant that meets the requirements of section 6.1.3 of the Listing Policy. Ten samples were taken in 1992 and 1999. Based on the readily available data and information, the weight of evidence indicates that there is insufficient information to justify placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that there is no sediment guideline for this pollutant that meets the requirements of section 6.1.3 of the Listing Policy. It is not possible to determine any exceedances and there is no significant toxicity associated with this water body segment. 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 cycle. The decision has not changed.
