Region 9     
San Diego Bay Shoreline, near sub base
 
Pollutant: Arsenic
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: 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: Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

This pollutant is being considered for removal from the section 303(d) list under section 4.9 of the Listing Policy. Under this section 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. None of samples exceeded the water quality criteria for benthic invertebrates.

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 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. None of the nineteen samples exceeded the water quality criteria for benthic invertebrates and this does not satisfy the minimum sample requirements to de-list according to Table 4.2 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.

The data for this site will be reassessed in future listing cycles in accordance with the California Sediment Quality Objectives.
 
Regional Board Decision Recommendation: Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

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.

Regional Board Conclusion: The decision has not changed from the previous listing cycle. No new data were assessed for the current listing cycle. Therefore, the previous conclusion remains unchanged, and is as follows:

This pollutant is being considered for removal from the section 303(d) list under section 4.1 of the Listing Policy. Under this section a single line of evidence is necessary to assess listing status. [In 2006, water toxicity had been included in the Sediment Toxicity listing]

Two lines of evidence are available in the administrative record to assess pollutant. Three of 14 samples exceed the water quality objective.

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 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. Three of 14 samples exceeded the toxicity water quality objective and this exceeds the allowable frequency listed in Table 4.1 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 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.

Beneficial Use: Marine Habitat
Aquatic Life Use: Marine Habitat
 
Number of Samples: 14
Number of Exceedances: 0
 
Data and Information Type: Toxicity testing of sediments
Data Used to Assess Water Quality: None of the 14 sediment samples were statistically significantly different from the control and below the minimum significant difference threshold for marine amphipods. Sample collection was conducted by Space and Naval Warfare Systems Center San Diego in April 2004 at Submarine Base San Diego.
Data Reference: Sediment Site Assessment Study, Submarine Base, San Diego, Draft Final Report.
 
SWAMP Data: Non-SWAMP
 
Water Quality Objective/Criterion: All waters shall be maintained free of toxic substances in concentrations that are toxic to, or that produce detrimental physiological responses in human, plant, animal, or aquatic life
Objective/Criterion Reference: Water Quality Control Plan for the San Diego Basin
 
Evaluation Guideline: The sample is consider toxic if there is statistically significant difference from the control and the minimum significant difference threshold is exceeded for the test species Eohaustorius estuarius.
Guideline Reference: Sediment Site Assessment Study, Submarine Base, San Diego, Draft Final Report.
 
Spatial Representation: Fourteen sampling stations were layed out in a grid pattern covering approximately 60 acres in around Piers November, Mike, and Sierra. Three of the stations are in the area originally listed as impaired on the current 303d list.
Temporal Representation: Samples were collected in April 2004.
Environmental Conditions:
QAPP Information: Sampling and analysis and quality assurance plans followed the general guidelines from previous San Diego Bay TMDL studies conducted by the Southern California Coastal Water Research Project, U.S. Navy, and the Regional Water Quality Control Board.

Data Used to Assess Water Quality: One of the 14 sediment samples were statistically significantly different from the control and below the minimum significant difference threshold for mussel larvae Mytilus galloprovincialis.

Three of the 14 sediment samples were statistically significantly different from the control and below the minimum significant difference threshold for purple sea urchin Strongylocentrotus purpuratus.
