Draft California 2014 Integrated Report (303(d) List/305(b) Report)

Supporting Information

Regional Board 4 - Los Angeles Region

Water Body Name:	Port Hueneme Harbor (Back Basins)
Water Body ID:	CAB4031100019990921141938
Water Body Type:	Bay & Harbor


DECISION ID	42748	Region 4
Port Hueneme Harbor (Back Basins)

Pollutant:	PCBs (Polychlorinated biphenyls)
Final Listing Decision:	Do Not Delist from 303(d) list (being addressed with action other than TMDL)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (being addressed by action other than TMDL)(2012)
Revision Status	Revised
Sources:	Source Unknown
Expected Attainment Date:	2019
Implementation Action Other than TMDL:	Port Hueneme Harbor includes several areas of contaminated sediments. The Oxnard Harbor District, the U.S. Navy, and the U.S. Army Corps of Engineers intend to dredge the Harbor to achieve necessary navigational depths and to remove all contaminated sediments. A final design has been developed and permitting for the project is in progress. The draft final design dredging report proposes to address the contaminated sediment through dredging removal of those sediments. The draft final design report presents the design for a plan to dredge contaminated sediments within the Port of Hueneme, and placement and confinement of the sediments in a subaqueous confined aquatic disposal (CAD) facility. The evaluation considered sampling data from 1965 through 2008. The identified ?depth-to-clean? to be achieved at all locations was calculated by determining the deepest elevations at which concentrations of DDT exceeded relevant risk based criteria. The risk based criteria for concentrations of DDT and its breakdown products were taken from a focused ecological risk assessment with bioaccumulation modeling. Sediments determined to have concentrations in excess of those criteria will be disposed of within the CAD facility.
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Staff Conclusion:	This pollutant is being considered for removal from the CWA section 303(d) List under section 4.5 of the Listing Policy. Under section 4.5 a single line of evidence is necessary to assess listing status. 7 lines of evidence are available in the administrative record to assess this pollutant. 4 of 4 samples exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 0 of 2 samples exceeded the GUIDELINE. 1 of 4 samples exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 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. 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 4, 0 of 0, 0 of 0, 0 of 2, 1 of 4, 0 of 0 and 0 of 0 samples exceeded the GUIDELINE and this exceeds the allowable frequency listed in Table 3.1 of the Listing Policy. 4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met.

Regional Board Staff 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.

DECISION ID	65882	Region 4
Port Hueneme Harbor (Back Basins)

Pollutant:	2-Methylnaphthalene
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 Staff Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.6 of the Listing Policy. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List. 1 line of evidence is available in the administrative record to assess this pollutant. 0 of 4 samples exceeded the GUIDELINE. Based on the readily available data and information, the weight of evidence indicates that there is INSUFFICIENT justification FOR placing this water segment-pollutant combination on the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 0 of 4 samples exceeded the GUIDELINE and this sample size is INSUFFICIENT to determine beneficial use support, with the power and confidence of the Listing Policy. There is not an associated sediment toxicity data as required by Section 3.6 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 Staff 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.

The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 0 of 4 samples exceeded the GUIDELINE and this sample size is INSUFFICIENT to determine beneficial use support, with the power and confidence of the Listing Policy. There is not an associated sediment toxicity data as required by Section 3.6 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 Staff 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.

Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List. 2 lines of evidence are available in the administrative record to assess this pollutant. 2 of the 4 samples exceed the GUIDELINE. 0 of the 4 samples exhibited sediment toxicity. Based on the readily available data and information, the weight of evidence indicates that there is INSUFFICIENT justification FOR placing this water segment-pollutant combination on the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 2 of the 4 samples exceeded the GUIDELINE, however, there is not an associated sediment toxicity data to support listing. 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 Staff Decision Recommendation:	After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating.

Data Used to Assess Water Quality:

Four samples were collected to evaluate sediment toxicity. Three of the samples exhibited significant toxicity but those samples were QA flagged for salinity in the samples interfering with the toxicity test. The toxicity test included survival of Eohaustorius estuarius. 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 with the same lab sample id (if provided).

DECISION ID	65911	Region 4
Port Hueneme Harbor (Back Basins)

Pollutant:	Endrin
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 Staff Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.5 of the Listing Policy. Under section 3.5 a single line of evidence are necessary to assess listing status. 3 lines of evidence are available in the administrative record to assess this pollutant. 0 of 4 samples exceeded the GUIDELINE. 0 of 2 samples exceeded the GUIDELINE. 0 of 4 samples exceeded the GUIDELINE. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for placing this water segment-pollutant combination on the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 0 of 4, 0 of 2 and 0 of 4 samples exceeded the GUIDELINE and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. 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 Staff 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.

DECISION ID	65888	Region 4
Port Hueneme Harbor (Back Basins)

Pollutant:	Lead
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 Staff Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.6 of the Listing Policy. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List. 1 line of evidence is available in the administrative record to assess this pollutant. 0 of 4 samples exceeded the GUIDELINE. Based on the readily available data and information, the weight of evidence indicates that there is INSUFFICIENT justification FOR placing this water segment-pollutant combination on the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 0 of 4 samples exceeded the GUIDELINE and this sample size is INSUFFICIENT to determine beneficial use support, with the power and confidence of the Listing Policy. There is not an associated sediment toxicity data as required by Section 3.6 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 Staff 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.

DECISION ID	65929	Region 4
Port Hueneme Harbor (Back Basins)

Pollutant:	Pyrene
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 Staff Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.6 of the Listing Policy. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List. 2 lines of evidence are available in the administrative record to assess this pollutant. 2 of the 4 samples exceed the GUIDELINE. 0 of the 4 samples exhibited sediment toxicity. Based on the readily available data and information, the weight of evidence indicates that there is INSUFFICIENT justification FOR placing this water segment-pollutant combination on the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 2 of the 4 samples exceeded the GUIDELINE, however, there is not an associated sediment toxicity data to support listing. 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 Staff 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.

Last Listing Cycle's Final Listing Decision:	New Decision
Revision Status	Revised
Sources:	Source Unknown
Expected TMDL Completion Date:	2027
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Staff Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.5 of the Listing Policy. Under section 3.5 a single line of evidence is necessary to assess listing status. 3 lines of evidence are available in the administrative record to assess this pollutant. 2 of 2 samples exceeded the GUIDELINE. 0 of 2 samples exceeded the GUIDELINE. 0 of 4 samples exceeded the GUIDELINE. 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, 0 of 2 and 0 of 4 samples exceeded the GUIDELINE 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 Staff 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	36221	Region 4
Port Hueneme Harbor (Back Basins)

Pollutant:	DDT (Dichlorodiphenyltrichloroethane)
Final Listing Decision:	Do Not Delist from 303(d) list (being addressed with action other than TMDL)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (being addressed by action other than TMDL)(2012)
Revision Status	Original
Sources:	Source Unknown
Expected Attainment Date:	2019
Implementation Action Other than TMDL:	Port Hueneme Harbor includes several areas of contaminated sediments. The Oxnard Harbor District, the U.S. Navy, and the U.S. Army Corps of Engineers intend to dredge the Harbor to achieve necessary navigational depths and to remove all contaminated sediments. A final design has been developed and permitting for the project is in progress. The draft final design dredging report proposes to address the contaminated sediment through dredging removal of those sediments. The draft final design report presents the design for a plan to dredge contaminated sediments within the Port of Hueneme, and placement and confinement of the sediments in a subaqueous confined aquatic disposal (CAD) facility. The evaluation considered sampling data from 1965 through 2008. The identified ?depth-to-clean? to be achieved at all locations was calculated by determining the deepest elevations at which concentrations of DDT exceeded relevant risk based criteria. The risk based criteria for concentrations of DDT and its breakdown products were taken from a focused ecological risk assessment with bioaccumulation modeling. Sediments determined to have concentrations in excess of those criteria will be disposed of within the CAD facility.
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Staff Conclusion:	This pollutant is being considered for removal from the CWA section 303(d) List under section 4.5 of the Listing Policy. Under section 4.5 a single line of evidence is necessary to assess listing status. 7 lines of evidence are available in the administrative record to assess this pollutant. 2 of 2 samples exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 0 of 2 samples exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 0 of 2 samples exceeded the GUIDELINE. 0 of 0 sample exceeded the GUIDELINE. 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. 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, 0 of 0, 0 of 2, 0 of 0, 0 of 0, 0 of 2 and 0 of 0 samples exceeded the GUIDELINE and this exceeds the allowable frequency listed in Table 3.1 of the Listing Policy. 4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met.

Regional Board Staff 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.
