DECISION ID	91508	Region 3
Pacific Ocean at Capitola Beach (Santa Cruz County)

Pollutant:	Fecal Coliform
Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)(2016)
Revision Status	Original
Sources:	A Source Unknown
Expected TMDL Completion Date:	2027
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for removal from the section 303(d) list under sections 4.2 and 4.3 of the Listing Policy. Under these sections, a single line of evidence is necessary to assess listing status. It should be noted that the data collected between 2007 and 2010 are E. coli results that are evaluated using the Ocean Plan Objective for Fecal Coliform. This objective is higher than the USEPA recreation criteria for E. coli. Evaluation of the data using the Fecal Coliform Objective could result in an erroneous decision to remove the beach segment from the 303(d) List and are not used here as the basis of a decision to de-list. Nine lines of evidence are available in the administrative record to assess this pollutant. Ninety nine of 1017 samples exceeded the geometric mean standard for fecal coliform (LOEs 3446, 19271, 19299, 56064 and 56065) and 92 of 1175 samples exceeded the single sample maximum for fecal coliform (LOEs 3446, 19272, 19300, 19304, and 56063) for the water contact recreation water quality standard (Water Quality Control Plan: Ocean Waters of California, SWRCB, 2005). The counts above include data summarized in LOE 3446 which describes two separate measurements for fecal coliform (55 of 422 samples exceeded the geometric mean standard for fecal coliform and 51 of 558 samples exceeded the single sample maximum for fecal coliform) for the water contact recreation water quality standard. Note that the 86 of 415 sample exceedances listed for LOE 3446 refers to the geometric mean standard for enterococcus and was not included in the calculated totals for fecal coliform (however, this number was included in the sample totals for the enterococcus, Decision ID 41513). 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. Although 99 of 1017 samples exceeded the geometric mean standard for fecal coliform (LOEs 3446, 19271, 19299, 56064 and 56065) and 92 of 1175 samples exceeded the single sample maximum for fecal coliform and this does not exceed the allowable frequency listed in Table 4.2 of the Listing Policy, some of these data are for E. coli and are incorrectly compared to the Fecal Coliform Objective. Therefore the decision must remain Do Not De-List. 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 not be removed from the section 303(d) List because applicable water quality standards for the pollutant are not used in this assessment. Some of the data included here are E. coli data and those data should not be assessed using the Fecal Coliform Objective.

State Board 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.

DECISION ID	80116	Region 3
Pacific Ocean at Capitola Beach (Santa Cruz County)

Pollutant:	Escherichia coli (E. coli)
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)(2016)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	No new data were assessed. This pollutant is being considered for placement on the section 303(d) list under sections 3.2 and 3.3 of the Listing Policy. Under these sections, a single line of evidence is necessary to assess listing status. This sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 26 samples is needed to determine if a beneficial use is supported using table 3.2. Therefore, the use support rating is set to 'insufficient information'. Two lines of evidence are available in the administrative record to assess this pollutant. When compared to the Ocean Plan Objectives for Water Contact Recreation, 1 of 6 samples exceeded the single sample maximum Objective, 2 of 2 geomean assessments exceeded the geomean Objective (Ambient Water Quality Criteria for Bacteria, USEPA, 1986). 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. When compared to the Ocean Plan Objectives for Water Contact Recreation, 1 of 6 samples exceeded the single sample maximum Objective, 2 of 2 geomean assessments exceeded the geomean Objective. Neither of these 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.

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.

State Board 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.

DECISION ID	77527	Region 3
Pacific Ocean at Capitola Beach (Santa Cruz County)

Pollutant:	Total Coliform
Final Listing Decision:	List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (TMDL required list)(2016)
Revision Status	Original
Sources:	A Source Unknown
Expected TMDL Completion Date:	2027
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the section 303(d) list under sections 3.2 and 3.3 of the Listing Policy. Under these sections, a single line of evidence is necessary to assess listing status. Thirteen lines of evidence are available in the administrative record to assess this pollutant. One hundred seventy three of 360 samples (LOE 56066) exceeded the shellfish harvesting water quality objective (Water Quality Control Plan: Ocean Waters of California, SWRCB, 2009). Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of 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. One hundred seventy three of 360 samples (LOE 56066) exceeded the shellfish harvesting water quality objective 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.

Regional Board Decision 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.

State Board 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.
