Revision Status Original
Impairment from Pollutant or Pollution: Pollution
 
Regional Board Conclusion: This pollutant is being considered for placement on the section 303(d) list under section 4.3 of the Listing Policy. Under section 4.3 a single line of evidence is necessary to assess listing status.

Sixteen lines of evidence are available in the administrative record to assess this pollutant. Seventeen of the 243 samples exceed the contact recreation single sample maximum water quality objective for enterococcus. One out of 38 samples exceeded the contact recreation geomean objective for enterococcus. Six out of 210 samples exceeded the contact recreation single sample maximum for Fecal Coliform. Zero out of 31 samples exceeded the contact recreation geomean objective for Fecal Coliform. Three of the 71 samples exceeded the shellfish harvesting single sample objective for Total Coliform. Five of the 84 samples exceeded the shellfish harvesting rolling 30 day geomean for Total Coliform. Zero of the 16 samples exceeded the Water Contact Recreation single sample geomean objective for Total Coliform. Zero of the 67 samples exceeded the Water Contact Recreation single sample water quality objective for Total Coliform.

The 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 (sections 3.3 and 4.3 of Listing Policy). There are two additional lines of evidence for dry weather single sample and geometric mean calculations. One of the 66 samples exceeded the Contact Recreation Single Sample Maximum Objective and Zero out of 61 samples exceeded the Dry Weather Contact Recreation Geomean Objective for enterococcus. One out of 38 samples exceeded the contact recreation dry weather single sample objective and Zero out of 62 samples exceeded the contact recreation geomean objective for Fecal Coliform. Zero out of 61 samples exceeded the contact recreation dry weather geomean objective for Total Coliform. The single sample and geometric mean results do not exceed the allowable limit in Section 3.3 of the listing Policy (at the applicable four percent exceedance percentage ¿ AB411).

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. Seventeen of the 243 samples exceed the contact recreation single sample maximum water quality objective for enterococcus. One out of 38 samples exceeded the contact recreation geomean objective for enterococcus. Six out of 210 samples exceeded the contact recreation single sample maximum for Fecal Coliform. Zero out of 31 samples exceeded the contact recreation geomean objective for Fecal Coliform. Three of the 71 samples exceeded the shellfish harvesting single sample objective for Total Coliform. Five of the 84 samples exceeded the shellfish harvesting rolling 30 day geomean for Total Coliform. Zero of the 16 samples exceeded the Water Contact Recreation single sample geomean objective for Total Coliform. Zero of the 67 samples exceeded the Water Contact Recreation single sample water quality objective for Total Coliform and this does not exceed the allowable frequency listed in Table 3.2 of the Listing Policy.
4. One of the 66 samples exceeded the Contact Recreation Single Sample Maximum Objective and Zero out of 61 samples exceeded the Dry Weather Contact Recreation Geomean Objective for enterococcus. One out of 38 samples exceeded the contact recreation dry weather single sample objective and Zero out of 62 samples exceeded the contact recreation geomean objective for Fecal Coliform. Zero out of 61 samples exceeded the contact recreation dry weather geomean objective for Total Coliform. The single sample and geometric mean results do not exceed the allowable limit in Section 3.3 of the listing Policy (at the applicable four percent exceedance percentage ¿ AB411).
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.

Data Used to Assess Water Quality: For the period from January 2001 to December 2007, there were eight beach advisory days for this section of shoreline. Bacteriological samples are collected on a weekly basis at ocean and bay locations in San Diego County. When a bacteriological sample exceeds water quality standards, signs are posted indicating that an advisory for waters have exceeded public health standards.

Data and information on the number of beach posting were summarized by the County of San Diego in their annual San Diego County Beach Closure and Advisory Reports. The reporting period was from January 2001 - December 2007. Data used was the number of days the beach was advisories were issued when the ocean or bay failed to meet the bacteriological standards.

The AB411 standard for enterococcus for the 30-day avg is 35 colonies/100mL, single sample maximum is 104 colonies/100 mL.

Spatial Representation: Samples were collected at the San Diego Bay Shoreline, Kellogg St. Samples were collected at 3 locations relative to each other: "Left," "middle," and "right."
Temporal Representation: Samples were collected from 04/27/1999 to 10/23/2003.
Environmental Conditions: Southern California has three distinct weather/hydrological conditions: summer dry weather, winter dry weather, and storm events. The data set used in this analysis includes summer and winter season data. Whether or not storm event samples are included in the data set are not known. For future water quality assessments, the RWQCB may classify bacteria samples as summer dry, winter dry, or storm event samples to ensure adequate representation of all three weather/hydrological conditions.
