Regional Board Conclusion: Region 2 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
 
Regional Board Decision Recommendation: No new data were assessed for 2012. The Regional Board will update this decision when new data and information become available and are assessed.
 
State Board Staff 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.

LOE ID: 444
 
Pollutant: Sediment Toxicity
LOE Subgroup: Toxicity
Matrix: Sediment
Fraction: None
 
Beneficial Use: Estuarine Habitat
 
Number of Samples: 20
Number of Exceedances: 4
 
Data and Information Type: Toxicity testing of sediments
Data Used to Assess Water Quality: BPTCP Data: Significant amphipod toxicity, 3 of 5 tests (60%) significant urchin toxicity (Hunt et al., 1998b). SWRCB received "Sediment Investigations at Islais Creek and Mission Creek-1998-1999-2000" provided by SFPUC. Six transects were monitored over three years and at corresponding North and South sampling stations for each transect (i.e. 1N, 1S). Excluding stations 5 and 6 (No data for 1999 and 2000), the data shows 4 of 20 sampling stations (1N/S-4N/S) indicate sediment toxicity and amphipod survival below the BPTCP reference tolerance limit (Battelle Memorial Institute, 2002).
Data Reference: Placeholder reference 2006 303(d)
 
SWAMP Data: Non-SWAMP
 
Water Quality Objective/Criterion: All waters shall be maintained free of toxic substances in concentrations that are lethal to or that produce other detrimental responses in aquatic organisms.

There shall be no chronic toxicity in ambient waters. Chronic toxicity is a detrimental biological effect on growth rate, reproduction, fertilization success, larval development, population abundance, community composition, or any other relevant measure of the health of an organism, population, or community.
Objective/Criterion Reference: Placeholder reference 2006 303(d)
 
Evaluation Guideline: BPTCP reference envelope approach used.
Guideline Reference: Placeholder reference 2006 303(d)
 
Spatial Representation: Data were collected concurrently with benthic and chemical measurements.
Temporal Representation: Data was collected from 5/95-4/97.
Environmental Conditions:
QAPP Information: BPTCP Quality Assurance Project Plan. SWRCB received "Sediment Investigations at Islais Creek and Mission Creek-1998-1999-2000" provided by SFPUC. Appropriate QA procedures were followed.

Evaluation Guideline: Evaluation of the benthic data were completed using the approaches developed by scientists associated with the BPTCP. The relative benthic index used is a calculated value considering the total fauna, total mollusk species, crustacean species and indicator species at a site. The index ranges from 0 to 1.0. An index value of less than or equal to 0.3 is an indication that pollutants or other factors are negatively impacting the benthic community (BPTCP, 1998).

Pollutant: Sediment Toxicity
LOE Subgroup: Toxicity
Matrix: Sediment
Fraction: None
 
Beneficial Use: Estuarine Habitat
 
Number of Samples: 21
Number of Exceedances: 4
 
Data and Information Type: Toxicity testing of sediments
Data Used to Assess Water Quality: Significant amphipod toxicity was observed in 4 of 21 samples. Observed toxicity was recorded in the year 2000 only (Battelle Memorial Institute, 2002).
Data Reference: Placeholder reference 2006 303(d)
 
SWAMP Data: Non-SWAMP
 
Water Quality Objective/Criterion: All waters shall be maintained free of toxic substances in concentrations that are lethal to or that produce other detrimental responses in aquatic organisms.

There shall be no chronic toxicity in ambient waters. Chronic toxicity is a detrimental biological effect on growth rate, reproduction, fertilization success, larval development, population abundance, community composition, or any other relevant measure of the health of an organism, population, or community (BPTCP, 1998).
Objective/Criterion Reference: Placeholder reference 2006 303(d)
 
Evaluation Guideline: BPTCP reference envelope approach used.
Guideline Reference: Placeholder reference 2006 303(d)
 
Spatial Representation: Data was synoptically collected with benthic community and toxicity measurements over the length of the creek.

Objective/Criterion Reference: Placeholder reference 2006 303(d)
 
Evaluation Guideline: Evaluation of the benthic data were completed using the approaches developed by scientists associated with the BPTCP. The relative benthic index used is a calculated value considering the total fauna, total mollusk species, crustacean species and indicator species at a site. The index ranges from 0 to 1.0. An index value of less than or equal to 0.3 is an indication that pollutants or other factors are negatively impacting the benthic community (BPTCP, 1998).

Evaluation Guideline: Evaluation of the benthic data were completed using the approaches developed by scientists associated with the BPTCP. The relative benthic index used is a calculated value considering the total fauna, total mollusk species, crustacean species and indicator species at a site. The index ranges from 0 to 1.0. An index value of less than or equal to 0.3 is an indication that pollutants or other factors are negatively impacting the benthic community (BPTCP, 1998).

Water Quality Objective/Criterion: All waters shall be maintained free of toxic substances in concentrations that are lethal to or that produce other detrimental responses in aquatic organisms.

There shall be no chronic toxicity in ambient waters. Chronic toxicity is a detrimental biological effect on growth rate, reproduction, fertilization success, larval development, population abundance, community composition, or any other relevant measure of the health of an organism, population, or community.
Objective/Criterion Reference: Placeholder reference 2006 303(d)
 
Evaluation Guideline: ERM of 410 ug/g used (Long et al., 1995).
Guideline Reference: Placeholder reference 2006 303(d)
 
Spatial Representation: Data was synoptically collected with benthic community and toxicity measurements over the length of the creek.
Temporal Representation: Data were collected between 1998 and 2000.
Environmental Conditions:
QAPP Information: Methods used were equivalent to those used in the BPTCP QAPP. All reported data met QA requirements.
