| Regional Board Conclusion: | This pollutant is being considered for placement on the CWA 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.
The sample size for the single sample maximum for enterococcus (LOE 56130) 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'. One line of evidence is available in the administrative record to assess this pollutant. Zero of 4 samples exceeded the single sample maximum for enterococcus (LOE 56130) for the water contact recreation water quality standard (Water Quality Control Plan: Ocean Waters of California, SWRCB, 2005). 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 CWA 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. Zero of 4 samples exceeded the single sample maximum for enterococcus (LOE 56130) for the water contact recreation water quality standard 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. |
| 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. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| State Board Decision Recommendation: | After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |

| Regional Board Conclusion: | This pollutant is being considered for placement on the CWA 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.
The sample size for the shellfish harvesting water quality objective criteria for total coliform (LOEs 361 and 56132) and the sample size for the single sample maximum criteria for total coliform (LOEs 360) are 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 for these LOEs are set to 'insufficient information'. Five lines of evidence are available in the administrative record to assess this pollutant. The data associated with LOE 359 (placeholder reference for assessments made prior to the 2006) is no longer available. However, it was stated that Monterey County posted Rain Advisories for all beaches in the county on 15 occasions from 2000 to 2004. Each advisory was posted for several days surrounding rain events in the county (CCRWQCB, 2004d). Four additional lines of evidence were assessed for this pollutant. Four of 19 samples (LOEs 361 and 56132) 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 against placing this water segment-pollutant combination on the CWA 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. Four of 19 samples (LOEs 361 and 56132) exceeded the shellfish harvesting water quality objective (Water Quality Control Plan: Ocean Waters of California, SWRCB, 2009). Zero of 15 samples exceeded the single sample maximum for total coliform (LOEs 360) for the water contact recreation water quality standard (Water Quality Control Plan: Ocean Waters of California, SWRCB, 2005) and none 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. |

| Data Used to Assess Water Quality: | Monterey County collected monthly bacteria samples at Seaside State Beach. Although because samples are monthly there is only 1 sample in each 30-day period, there is no limit as to how many samples must be included in the 30-day median total coliform concentration. A ten percent total coliform concentration could not be calculated either, so this criterion was used as a single (monthly) sample comparison as well. Four of 15 samples exceeded the criteria of 70/100 ml and 0 of 15 samples exceeded the criteria of 230/100 ml (CCRWQCB, 2004d). | ||||

| 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. |
