Water Body Name: | Pacific Ocean at Capitola Beach (Santa Cruz County)
Water Body ID: | CAX3041301420021001205532
Water Body Type: | Coastal & Bay Shoreline

DECISION ID | 6033
Pollutant: | Indicator Bacteria
Final Listing Decision: | 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
Reason for Delisting: | Change from general pollutant to specific pollutant listing (e.g. metals to copper)
Impairment from Pollutant or Pollution: | Pollutant
Weight of Evidence: | Currently, Pacific Ocean at Capitola Beach (Santa Cruz County), is listed for Indicator Bacteria. It is not possible, in a general listing, to determine which specific pollutant is causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for Indicator Bacteria from the 303(d) list and replace this general listing with decisions for each of the specific pollutants that apply. See decisions for Enterococcus, fecal coliform and total coliform.
RWQCB Board Decision / Staff Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be removed from the section 303(d) list because the general pollutant "Indicator Bacteria" will be replaced by assessments for each of the individual indicators.
SWRCB Board Decision / Staff Recommendation: | N/A
USEPA Decision: | The USEPA final decision for the 2006 303(d) list was to list this water body segment for indicator bacteria.

Impairment from Pollutant or Pollution: | Pollutant
Weight of Evidence: | This pollutant 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 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. 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.
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 pollutant 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. Nine lines of evidence are available in the administrative record to assess this pollutant. Data was collected at three monitoring locations along Capitola Beach. Data from each monitoring location is summarized below. Three LOEs summarize data collected from Capitola Beach west of the Jetty (LOEs #19334, #19335 and #19336). When compared to the Ocean Plan Objectives for Water Contact Recreation, 4 of 133 samples exceeded the single sample maximum Objective and 2 of 24 geomean assessments exceeded the geomean Objective and 7 of 115 samples exceeded the total to fecal coliform ratio Objective. Two LOEs summarize data collected from Capitola Beach east of the Jetty (LOEs #19331, #19332 and #19333). When compared to the Ocean Plan Objectives for Water Contact Recreation, 2 of 124 samples exceeded the single sample maximum Objective and 2 of 24 geomean assessments exceeded the geomean Objective and 1 of 107 samples exceeded the total to fecal coliform ratio Objective. Three LOEs summarize data collected from Capitola Beach at Soquel Creek Mouth (LOEs #19358, #19359 and #19360). When compared to the Ocean Plan Objectives for Water Contact Recreation, 0 of 6 samples exceeded the single sample maximum Objective and 0 of 2 geomean assessments exceeded the geomean Objective and 0 of 1 samples exceeded the total to fecal coliform ratio Objective. 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. None of the LOEs summarize data that 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 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 pollutant is being considered for placement on the section 303(d) list under sections 2.1 and 3.3 of the Listing Policy. Six lines of evidence are available in the administrative record to assess this pollutant at three separate monitoring locations along Capitola Beach. Each beach assessment is discussed below. Two LOEs summarize data collected from Capitola Beach west of the Jetty (LOEs #19301 and #19302). When compared to the Ocean Plan Objectives for Water Contact Recreation, 17 of 130 samples exceeded the single sample maximum Objective. However, 6 of 24 geomean assessments exceeded the geomean Objective and this exceeds the allowable frequency listed in Table 3.2 of the Listing Policy. Two LOEs summarize data collected from Capitola Beach east of the Jetty (LOEs #19273 and #19274). When compared to the Ocean Plan Objectives for Water Contact Recreation, 6 of 123 samples exceeded the single sample maximum Objective and 2 of 24 geomean assessments exceeded the geomean Objective. Two LOEs summarize data collected from Capitola Beach at Soquel Creek Mouth (LOEs #19305 and #19306). When compared to the Ocean Plan Objectives for Water Contact Recreation, 1 of 6 samples exceeded the single sample maximum Objective and 1 of 2 geomean assessments exceeded the geomean Objective. Based on section 3.3 the site exceeded numeric objectives for conventional pollutants. According to the binomial distribution, waters shall be placed on the section 303(d) list if the number of measured exceedances supports rejection of the null hypothesis as presented in Table 3.2. 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. Six of 24 geomean assessments (collected at Capitola Beach west of the Jetty) exceeded the Ocean Plan water quality objective for Water Contact Recreation 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.

DECISION ID | 15574
Pollutant: | Fecal Coliform
Final Listing Decision: | List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision: | New Decision
Revision Status | Revised
Sources: | Natural Sources | Other Urban Runoff | Source Unknown
Expected TMDL Completion Date: | 2021
Impairment from Pollutant or Pollution: | Pollutant
Weight of Evidence: | This pollutant is being considered for placement on the section 303(d) list under sections 2.1 and 3.3 of the Listing Policy. Five lines of evidence are available in the administrative record to assess this pollutant at three separate monitoring locations along Capitola Beach. Each beach assessment is discussed below. Two LOEs summarize data collected from Capitola Beach west of the Jetty (LOEs #19300 and #19299). When compared to the Ocean Plan Objectives for Water Contact Recreation, 14 of 116 samples exceeded the single sample maximum Objective. However, 5 of 21 geomean assessments exceeded the geomean Objective and this exceeds the allowable frequency listed in Table 3.2 of the Listing Policy. Two LOEs summarize data collected from Capitola Beach east of the Jetty (LOEs #19271 and #19272). When compared to the Ocean Plan Objectives for Water Contact Recreation, 4 of 108 samples exceeded the single sample maximum Objective and 1 of 23 geomean assessments exceeded the geomean Objective. One LOE summarizes data collected from Capitola Beach at Soquel Creek Mouth (LOEs #19304). When compared to the Ocean Plan Objective for Water Contact Recreation, 1 of 1 samples exceeded the single sample maximum Objective. Based on section 3.3 the site exceeded numeric objectives for conventional pollutants. According to the binomial distribution, waters shall be placed on the section 303(d) list if the number of measured exceedances supports rejection of the null hypothesis as presented in Table 3.2. 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. Five of 21 geomean assessments (collected at Capitola Beach west of the Jetty) exceeded the Ocean Plan water quality objective for Water Contact Recreation 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.
