Water Body Name: | Pacific Ocean at Spanish Bay Beach
Water Body ID: | CAC3095004220041214171644
Water Body Type: | Coastal & Bay Shoreline

DECISION ID | 4624
Pollutant: | Enterococcus
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)(2006)
Revision Status | Revised
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. Six lines of evidence are available in the administrative record to assess this pollutant at Spanish Bay Beach. Four lines of evidence summarize the data and information used in the 2006 assessment. Those data are summarized here. One of 61 sample geomeans were in exceedance of the Objective for Water Contact Recreation, 2 of 110 samples were in exceedance of the single sample Objective for Water Contact Recreation for Enterococcus. Neither of these exceed the allowable frequency listed in Table 3.1 of the Listing Policy. Nine advisories/warnings were posted from 1999 to 2003. Rain Advisories for all beaches in the county were posted on 15 occasions from 2000 to 2004. Two additional Lines of evidence summarize more recent weekly data collected between February 2005 and October 2006. One of the 61 samples samples were in exceedance of the single sample Objective for Water Contact Recreation for Enterococcus and none of the 16 sample geomeans were in exceedance of the Objective for Water Contact Recreation. Based on section 3.3 the site does not have significant bacterial contamination. 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 Assembly Bill 411 criteria used complies with the requirements of section 6.1.3 of the Policy. 2. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 3. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 4. Based on section 3.3 the site does not have significant bacterial contamination. 5. 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.
SWRCB Board Decision / Staff 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 applicable water quality standards for the pollutant are not exceeded.

Data Used to Assess Water Quality: | Monterey County posted a total of 9 advisories/warnings for Spanish Bay Beach from in 1999, 2000, 2001, and 2004. The warnings were for high bacteria (fecal coliform and enterococcus). Additionally, there was one closure for a sewage spill (possible broken pipe) in 2000 (CCRWQCB, 2004d).
Data Reference: | Placeholder reference 2006 303(d)
Water Quality Objective/Criterion: | Assembly Bill 411: Weekly monitoring is required from April to October at all beaches with more than 50,000 annual visitors or at beaches located in areas adjacent to storm drains that flow during the summer. Some counties continue testing year round. Weekly samples must be tested for three indicator organisms: total coliform, fecal coliform, and enterococcus. Beaches that fail to meet the state's criteria for any one of the three indicators are to be posted with conspicuous warning signs to notify the public of health risks associated with swimming in these areas. Closings and advisories are issued on a discretionary basis. AB 411 requires the State Water Resources Control Board (SWRCB) to post monthly beach data from coastal counties throughout the state. The surveys list beach warnings, beach closures, and rain advisories resulting from bacterial contamination.

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. Zero of three samples exceeded the single sample maximum criterion and zero of three 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. However, there are an insufficient number of samples to make a "use rating" decision. Central Coast Water Board staff require a minimum of 26 samples to make a "use rating" decision of Fully Supporting. 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. Zero of three samples exceeded the single sample maximum criterion and zero of three geomean assessments exceeded the geomean criterion and this does not 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.

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). Zero of 60 samples exceeded the single sample maximum criterion and zero of 16 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.
