Regional Board Conclusion:	Region 3 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
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 the sample size is insufficient to determine with the power and confidence of the Listing Policy if water quality standards are being met.
State Board Staff Review of Regional Board Conclusion and Recommendation:
State Board Decision Recommendation:	After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because it cannot be determined if applicable water quality standards are not being exceeded.

Data Reference:	Final Data File used for assessment: SWAMP Toxicity Data 2001-06
SWAMP Data:	SWAMP
Water Quality Objective/Criterion:	All waters shall be maintained free of toxic substances in concentrations which are toxic to, or which produce detrimental physiological responses in, human, plant, animal, or aquatic life. Compliance with this objective will be determined by use of indicator organisms, analyses of species diversity, population density, growth anomalies, toxicity bioassays of appropriate duration, or other appropriate methods as specified by the Regional Board (Water Quality Control Plan, Central Coast Basin, Chapter III, Section II.A.2 Objectives for all Inland Surface Waters, Enclosed Bays and Estuaries).
Objective/Criterion Reference:	Water Quality Control Plan (Basin Plan) - Central Coast Region (Region 3)
Evaluation Guideline:	Significant reduction of survival of test organism relative to the control (alpha < 0.05) and test organism survival is 20% less than the control survival.

Pollutant:	Zinc
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)(2010)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant
Regional Board Conclusion:	Region 3 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
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 the sample size is insufficient to determine with the power and confidence of the Listing Policy if water quality standards are being met.
State Board Staff Review of Regional Board Conclusion and Recommendation:
State Board Decision Recommendation:	After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because it cannot be determined if applicable water quality standards are not being exceeded.

Data Used to Assess Water Quality:	Central Coast Regional Board Staff assessed CCAMP Santa Barbara (SantaBarb) data for Devereux Creek to determine beneficial use support and results are as follows: 2 of 14 samples exceed the criterion for Oxygen, Dissolved.
Data Reference:	Final Data File used for assessment: CCAMP Water Quality Data_file1
	Final Data File used for assessment: CCAMP Water Quality Data_file2
	Final Data File used for assessment: CCAMP Water Quality Data_file3
SWAMP Data:	SWAMP
Water Quality Objective/Criterion:	Water Quality Control Plan, Central Coast Basin, General Objective, Chapter III, Section II.A.2 General Objectives for all Inland Surface Waters, Enclosed Bays and Estuaries states the following: For waters not mentioned by a specific beneficial use, dissolved oxygen concentration shall not be reduced below 5.0 mg/l at any time.
Objective/Criterion Reference:	Water Quality Control Plan (Basin Plan) - Central Coast Region (Region 3)
Evaluation Guideline:
Guideline Reference:
Spatial Representation:	Data for this line of evidence for Devereux Creek was collected at 1 monitoring site [ 315DEV-Devereux Slough at the Golf Course culvert]
Temporal Representation:	Data was collected over the time period 2/13/2001-3/7/2002. Santa Barbara Coast is one of five annual rotation areas that are monitored for conventional pollutants by CCAMP staff monthly for one year. Toxicity monitoring is conducted twice during the rotation year (winter and summer) at a subset of sites.
Environmental Conditions:	Staff is not aware of any special conditions that might effect interpretation of the data.
QAPP Information:	All data was collected following the Standard Operating Procedures and Data Quality Objectives outlined in the SWAMP QAMP, (Puckett, 2002). QA data are included in submission. All data are flagged as appropriate.
