Water Body Name:	Pacific Ocean at Hammonds Beach (Santa Barbara County)
Water Body ID:	CAX3153301020021002211858
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	6569

Pollutant:	Fecal Coliform
Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (TMDL required list)(2006)
Revision Status	Revised
Sources:	Source Unknown
Expected TMDL Completion Date:	2011
Impairment from Pollutant or Pollution:	Pollutant

Weight of Evidence:	This pollutant is being considered for removal from the section 303(d) list under section 4.3 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 Fecal Coliform consistent with Listing Policy, Section 4.3. These lines of evidence contain weekly data collected from January 2004 to December 2006 and demonstrate that applicable water quality standards for Fecal Coliform are not being exceeded in this water segment during this time period. However, this data is not Fecal Coliform, as it is identified in the data file, but instead is E. coli data. Staff assessed these data relative to the Ocean Plan objective for Fecal Coliform. Staff is not aware of any marine objective or criteria for E. coli and State Board staff support assessment of E. coli data using the Ocean Plan Objective for Fecal Coliform. The original assessment resulted in the following recommendations to change the 2006 List of Impaired Waterbodies: five recommendations to de-list and one recommendation to List. However, staff no longer supports these decisions and instead recommends that no beach be de-listed due to the flawed assessment of Fecal Coliform data. Staff plans to conduct a comprehensive assessment of beach E. coli data as part of the 2010 Integrated Report, in coordination with the State Water Board and USEPA. When compared to the Ocean Plan criteria for Water Contact Recreation, three of 150 samples exceeded the single sample maximum Objective for Water Contact Recreation and zero of 32 geomean assessments exceeded the geomean Objective for Water Contact Recreation. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for 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 150 samples exceeded the single sample maximum Objective for Water Contact Recreation and zero of 32 geomean assessments exceeded the geomean Objective for Water Contact Recreation. Neither of these exceed the allowable frequency listed in Table 4.2 of the Listing Policy. However, staff does not support de-listing until the errors in the data and the assessment method has been resolved with State Water Board Staff. 4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

RWQCB Board Decision / Staff Recommendation:	After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be not removed from the section 303(d) list because of errors in the data and unresolved data assessment methods

Pollutant:	Enterococcus
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

Weight of Evidence:	This water segment-pollutant combination is being considered for placement on the section 303(d) list under section 3.3 of the Listing Policy. Under section 3.3 a single line of evidence is necessary to assess listing status. Two lines of evidence are available in the administrative record to assess this water segment-pollutant combination. Water Board staff assessed one data set against two different evaluation criteria (i.e. single sample maximum and geomean). Ten of 151 samples exceeded the single sample maximum Objective for Water Contact Recreation and four of 32 geomean assessments exceeded the geomean Objective for Water Contact Recreation. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against 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. Ten of 151 samples exceeded the single sample maximum Objective for Water Contact Recreation and four of 32 geomean assessments exceeded the geomean Objective for Water Contact Recreation. Neither of these exceed the allowable frequency listed in Table 3.2 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

RWQCB Board Decision / Staff 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.

Impairment from Pollutant or Pollution:	Pollutant

Weight of Evidence:	This water segment-pollutant combination is being considered for placement on the section 303(d) list under section 3.3 of the Listing Policy. Under section 3.3 a single line of evidence is necessary to assess listing status. Three lines of evidence are available in the administrative record to assess this water segment-pollutant combination. Water Board staff assessed one data set against three different water quality objective set to protect for Water Contact Recreation (i.e. single sample maximum, geomean, and total to fecal ratio). Nine of 150 samples exceeded the single sample maximum Objective for Water Contact Recreation, two of 32 geomean assessments exceeded the geomean Objective for Water Contact Recreation, and zero of 149 sample ratio exceeded the total to fecal ratio Objective for Water Contact Recreation. However, Water Board staff also assessed this same data compared to the Ocean Plan Objective for Shellfish Harvesting and 48 of 150 samples exceeded this water quality objective. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category due to exceedances of the Ocean Plan Objective for Shellfish Harvesting. 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. Forty-eight of 150 samples exceeded the Ocean Plan Objective for Shellfish Harvesting and this exceeds the allowable frequency listed in Table 3.2 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.

RWQCB Board Decision / Staff 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.
