DECISION ID	6563	Region 3
Pacific Ocean at Carpinteria State Beach (Carpinteria Creek mouth, Santa Barbara County)

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

Regional Board Conclusion:	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. 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 Objectives for Water Contact Recreation, seven of 154 samples exceeded the single sample maximum Objective for Water Contact Recreation and none 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. Seven of 154 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.

Regional Board Decision 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.

State Board 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 removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded.

USEPA Action (if applicable):	USEPA approved the listing of this water body as a water quality limited segment requiring a TMDL for this pollutant.

DECISION ID	10625	Region 3
Pacific Ocean at Carpinteria State Beach (Carpinteria Creek mouth, Santa Barbara County)

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

Regional Board Conclusion:	Regional Board Conclusion: 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 water quality objectives (i.e. single sample maximum and geomean). Seventeen of 155 samples exceeded the single sample maximum criterion and five of 32 geomean assessments exceeded the geomean criterion. 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. Seventeen of 155 samples exceeded the single sample maximum criterion and five of 32 geomean assessments exceeded the geomean criterion . 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. State Board Review and Conclusion: Based on comments received from U.S. EPA (comment letter # 60), on the April 19, 2010 State Water Board staff report for the 2010 Integrated Report, State Water Board staff added 2 LOE's (31450 and 31451) asessing the AB411 (dry weather) data for this waterbody. Staff reviewed the bacteria data for this water body in the Central Coast Region described in the comment letter. Staff recommendation has not changed for this water body - pollutant combination based on evaluation of the dry weather data that was not included in the original Central Coast Region assessment. On August 4, 2010 the State Water Board approved the staff listing recommendation to not place this water body on the 303(d) list for enterococcus. The final language for the recommendation is: 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 water quality objectives (i.e. single sample maximum and geomean). Seventeen of 155 samples exceeded the single sample maximum criterion and five of 32 geomean assessments exceeded the geomean criterion. This water body segment is identified as an AB411 beach and data collected during the time frame of April 1st to October 31st (dry weather) is assessed using a four percent exceedance percentage (section 3.3 of Listing Policy). There are two additional lines of evidence for dry weather single sample and geometric mean calculations. Seven of 90 samples exceeded the recreational use single sample criteria and one of 19 geo-metric mean calculations exceeded the geo-metric mean criteria. These do exceed the allowable frequency listed in Table 3.2 of the Listing Policy 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. Seventeen of 155 samples exceeded the single sample maximum criterion and five of 32 geomean assessments exceeded the geomean criterion .

These do exceed the allowable frequency listed in Table 3.2 of the Listing Policy. 5. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

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 applicable water quality standards are not being exceeded.
