Pacific Ocean Shoreline, Scripps HA, at Childrens Pool
 
Pollutant: Indicator Bacteria
Final Listing Decision: Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL)
Last Listing Cycle's Final Listing Decision: Do Not Delist from 303(d) list (TMDL required list)(2012)
Revision Status Revised

TMDL Name: Bacteria Impaired Waters I (creeks and beach shorelines)
TMDL Project Code: 169
Date TMDL Approved by USEPA: 06/22/2011
Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for removal from the section 303(d) list under section 4.3 of the Listing Policy. Under this section a single line of evidence is necessary to assess listing status.

Ten lines of evidence are available in the administrative record to assess this pollutant. Eighty-three of 106 samples exceed the Shellefish Harvesting water quality objective for Total Coliform. Two out of 106 samples exceeded the contact recreation single sample maximum evaluation guideline for total Coliform. Eleven out of 35 monthly geomeans exceeded the contact recreation evaluation guideline for Total Coliform. Fifty-Five out of 106 samples exceeded the contact recreation single sample maximum objective for Fecal Coiliform. Four out of 34 monthly geomeans exceeded the contact recreation objective for fecal coliform. Four out of 106 samples exceeded the contact recreation single sample maximum and five out of 34 monthly geomeans exceeded the objective for enterococcus.

This 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 (section 4.3 of Listing Policy). There are fhree additional lines of evidence for dry weather single sample. Two of 100 samples exceeded the recreational use single sample criteria. Fifty-Two out of 100 samples exceeded the contact recreation objective for fecal coliform and six out of 26 dry month geomeans exceeded the contact recreation objective for enterococcus.

Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against 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. Eighty-three of 106 samples exceed the Shellefish Harvesting water quality objective for Total Coliform. Two out of 106 samples exceeded the contact recreation single sample maximum evaluation guideline for total Coliform. Eleven out of 35 monthly geomeans exceeded the contact recreation evaluation guideline for Total Coliform. Fifty-Five out of 106 samples exceeded the contact recreation single sample maximum objective for Fecal Coiliform. Four out of 34 monthly geomeans exceeded the contact recreation objective for fecal coliform. Four out of 106 samples exceeded the contact recreation single sample maximum and five out of 34 monthly geomeans exceeded the objective for enterococcus and this exceeds the allowable frequency listed in Table 4.2 of the Listing Policy.
4. There are fhree additional lines of evidence for dry weather single sample. Two of 100 samples exceeded the recreational use single sample criteria. Fifty-Two out of 100 samples exceeded the contact recreation objective for fecal coliform and six out of 26 dry month geomeans exceeded the contact recreation objective for enterococcus, and this does not exceed the allowable limit listed in Table 4.2 (at a four percent exceedance percentage ? AB411) of the Listing Policy.
5. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are 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 being exceeded.
 
State Board Review of Regional Board Conclusion and Recommendation: 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. Eighty-three of 106 samples exceed the Shellefish Harvesting water quality objective for Total Coliform. Two out of 106 samples exceeded the contact recreation single sample maximum evaluation guideline for total Coliform. Eleven out of 35 monthly geomeans exceeded the contact recreation evaluation guideline for Total Coliform. Fifty-Five out of 106 samples exceeded the contact recreation single sample maximum objective for Fecal Coiliform. Four out of 34 monthly geomeans exceeded the contact recreation objective for fecal coliform. Four out of 106 samples exceeded the contact recreation single sample maximum and five out of 34 monthly geomeans exceeded the objective for enterococcus and this exceeds the allowable frequency listed in Table 4.2 of the Listing Policy.
4. There are fhree additional lines of evidence for dry weather single sample. Two of 100 samples exceeded the recreational use single sample criteria. Fifty-Two out of 100 samples exceeded the contact recreation objective for fecal coliform and six out of 26 dry month geomeans exceeded the contact recreation objective for enterococcus, and this does not exceed the allowable limit listed in Table 4.2 (at a four percent exceedance percentage ? AB411) of the Listing Policy.

For the 2008 assessment , the 2006 listed coastline 'Pacific Ocean Shoreline, Scripps HA' was split into smaller segments and each represents an area near the sampling location of the data being assessed. This segment 'Pacific Ocean Shoreline, Scripps HA, at Childrens Pool' is one of the sampling locations. This LOE is a copy of the 2006 listing placeholder LOE for Pacific Ocean Shoreline, Scripps HA and is considered by the Regional Board to be applicable to this more specific segment formed from the split.

Analyzing only storm water bacteria data is important because the majority of beach monitoring data covers the months of April through October. The data may not capture the full impacts of seasonal storm events and high bacteria levels due to storm water runoff because much of the wet season for Southern California occurs in November through March.

Data Used to Assess Water Quality: For the period from January 2001 to December 2007, there was a year round beach advisory for this section of shoreline due to the presence of marine mammals.

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.
