Pacific Ocean Shoreline, San Elijo HSA, at Cardiff State Beach at San Elijo Lagoon

Pollutant:	Enterococcus
Final Listing Decision:	Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Delist from 303(d) list (TMDL required list)(2010)
Revision Status	Original

Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. In 2006, 'Pacific Ocean Shoreline, Escondido Creek HA' was listed for Indicator Bacteria. For 2008, the 2006 Escondido Creek HA segment has been renamed to San Elijo HSA and split into smaller segments that each represent an area near the sampling location of the data being assessed. 'Pacific Ocean Shoreline, San Elijo HSA, at Cardiff State Beach at San Elijo Lagoon' is one of the sampling locations and is considered to be part of the original listing. For this 2008 assessment, the Regional Board has chosen to replace the 'indicator bacteria' listing with separate assessments of the specific indicator bacteria, such as coliform, fecal coliform, and enterococcus, for removal or non-removal from the 303(d) list. This pollutant is being considered for removal from the section 303(d) list under section 4.2 of the Listing Policy. Under section 4.2 a single line of evidence is necessary to assess listing status. Two line of evidence is available in the administrative record to assess this pollutant. One of the 35 samples exceed the Basin Plan geometric mean water quality objective and twenty-one of the 300 samples exceed the Basin Plan single sample maximum for enterococcus. The coastal beach at this water segment is identified as an AB411 beach. To comply with the requirements of AB411 the dry weather data collected during the time frame of April 1st to October 31st is assessed using a four percent exceedance percentage, as described in section 3.3 and 4.3 of the Listing Policy. An assessment for dry weather geometric mean calculation was conducted and three additional lines of evidence are available in the administrative record. One of 171 single samples exceeded criteria. Zero of 26, 2 of 16, and 3 of 187 geometric mean calculations exceeded the criteria for recreational use and this does not exceed the allowable limit based on the application of a four percent exceedance percentage (AB411) to section 4.3 of the Listing Policy. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for removing 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. One of the 35 samples exceed the Basin Plan geometric mean water quality objective and twenty-one of the 300 samples exceed the Basin Plan single sample maximum for enterococcus and this does not exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. Five of 229 geometric mean calculations exceeded the criteria for recreational use and this does not exceed the allowable limit based on the application of a four percent exceedance percentage (AB411) to section 4.3 of the Listing Policy. 5. One of 171 single samples 5. dry weather geometric mean calculations exceeded the total coliform criteria for recreational use and this does not exceed the allowable limit (at a four percent exceedance percentage - AB411) in section 4.3 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 not met.

Regional Board Decision Recommendation:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. 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 applicable water quality standards are being met.

State Board Staff Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should be removed from the section 303(d) list because applicable water quality standards for the pollutant are not exceeded.

DECISION ID	29824	Region 9
Pacific Ocean Shoreline, San Elijo HSA, at Cardiff State Beach at San Elijo Lagoon

Pollutant:	Fecal Coliform
Final Listing Decision:	Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Delist from 303(d) list (TMDL required list)(2010)
Revision Status	Original
Reason for Delisting:	Applicable WQS attained; reason for recovery unspecified
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. In 2006, 'Pacific Ocean Shoreline, Escondido Creek HA' was listed for Indicator Bacteria. For 2008, the 2006 Escondido Creek HA segment has been renamed to San Elijo HSA and split into smaller segments that each represent an area near the sampling location of the data being assessed. 'Pacific Ocean Shoreline, San Elijo HSA, at Cardiff State Beach at San Elijo Lagoon' is one of the sampling locations and is considered to be part of the original listing. For this 2008 assessment, the Regional Board has chosen to replace the 'indicator bacteria' listing with separate assessments of the specific indicator bacteria, such as coliform, fecal coliform, and enterococcus, for removal or non-removal from the 303(d) list. This pollutant is being considered for placement on the section 303(d) list under section 4.2 of the Listing Policy. Under section 4.2 a single line of evidence is necessary to assess listing status. Three lines of evidence are available in the administrative record to assess this pollutant. None of the 27 samples exceed the Basin Plan geometric mean water quality objective and eight of the 197 samples exceed the Basin Plan single sample maximum for fecal coliform. The coastal beach at this water segment is identified as an AB411 beach. To comply with the requirements of AB411 the dry weather data collected during the time frame of April 1st to October 31st is assessed using a four percent exceedance percentage, as described in section 3.3 and 4.3 of the Listing Policy. An assessment for dry weather single sample and the geometric mean calculation was conducted and two additional lines of evidence are available in the administrative record. Five of 188 dry weather single samples exceeded the criteria for recreational use and this does not exceed the allowable limit based on the application of a four percent exceedance percentage (AB411) to section 4.3 of the Listing Policy. Zero of 18 dry weather geometric mean calculations exceeded the criteria for recreational use; however, the 18 samples are below the minimum of 22 required to conduct an assessment and is not considered in this Decision. In LOE 27465, the Regional Board calculated exceedances for samples taken only during storm events. This information was not used in determining listing decisions, but is of interest to the Regional Board and has been included as additional anecdotal information. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for removing 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 27 samples exceed the Basin Plan geometric mean water quality objective and eight of the 197 samples exceed the Basin Plan single sample maximum for fecal coliform and this does not exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. Five of 188 dry weather single samples exceeded the criteria for recreational use and this does not exceed the allowable limit based on the application of a four percent exceedance percentage (AB411) to section 4.3 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 not met.

Regional Board Decision Recommendation:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. 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 applicable water quality standards are being met.

DECISION ID	29607	Region 9
Pacific Ocean Shoreline, San Elijo HSA, at Cardiff State Beach at San Elijo Lagoon

Pollutant:	Total Coliform
Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)(2010)
Revision Status	Original
Sources:	Source Unknown
Expected TMDL Completion Date:	2008
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. In 2006, 'Pacific Ocean Shoreline, Escondido Creek HA' was listed for Indicator Bacteria. For 2008, the 2006 Escondido Creek HA segment has been renamed to San Elijo HSA and split into smaller segments that each represent an area near the sampling location of the data being assessed. 'Pacific Ocean Shoreline, San Elijo HSA, at Cardiff State Beach at San Elijo Lagoon' is one of the sampling locations and is considered to be part of the original listing. For this 2008 assessment, the Regional Board has chosen to replace the 'indicator bacteria' listing with separate assessments of the specific indicator bacteria, such as coliform, fecal coliform, and enterococcus, for removal or non-removal from the 303(d) list. This pollutant is being considered for removal from the section 303(d) list under section 4.2 of the Listing Policy. Under section 4.2 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. One hundred seventeen out of 302 samples exceed the Basin Plan water quality objective for total coliform for the shellfish harvesting beneficial use. The coastal beach at this water segment is identified as an AB411 beach. To comply with the requirements of AB411 the dry weather data collected during the time frame of April 1st to October 31st is assessed using a four percent exceedance percentage, as described in section 3.3 (and 4.3) of the Listing Policy. An assessment for dry weather single sample and the geometric mean calculation was conducted and two additional lines of evidence are available in the administrative record. Fourteen of 291single samples exceeded the criteria for recreational use and this does not exceed the allowable limit based on the application of a four percent exceedance percentage (AB411) to section 4.3 of the Listing Policy. Four of 26 geometric mean calculations exceeded the total coliform criteria for recreational use and this exceeds the allowable limit (at a four percent exceedance percentage - AB411) in section 4.3 of the Listing Policy. In LOEs 27417 and 27444, the Regional Board calculated exceedances for samples taken only during storm events. This information was not used in determining listing decisions, but is of interest to the Regional Board and has been included as additional anecdotal information. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against for removing 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. One hundred seventeen out of 302 samples exceed the Basin Plan water quality objective for total coliform for the shellfish harvesting beneficial use and this exceeds the allowable frequency listed in Table 4.2 of the Listing Policy. 4. Fourteen of 291 dry weather single samples exceeded the total coliform criteria for recreational use and this does not exceed the allowable limit (at a four percent exceedance percentage - AB411) in section 4.3 of the Listing Policy. 5. Four of 26 dry weather geometric mean calculations exceeded the total coliform criteria for recreational use and this exceeds the allowable limit (at a four percent exceedance percentage - AB411) in section 4.3 of the Listing Policy 6. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

Regional Board Decision Recommendation:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. 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 Staff Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	Region 9 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. After review of the available data and information, SWRCB 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.
