Water Body Name:	Pacific Ocean Shoreline, Mission San Diego HSA, at Newport Ave
Water Body ID:	2007
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	16338

Pollutant:	Enterococcus
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	New Decision
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. Four lines of evidence are available in the administrative record to assess this pollutant. Seven of the samples exceed the water quality objective for enterococcus. 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 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. Seven of 228 samples exceeded the enterococcus water quality objective 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.

LOE ID:	27728

Pollutant:	Enterococcus
LOE Subgroup:	Pollutant-Water
Matrix:	Water
Fraction:	None

Beneficial Use:	Water Contact Recreation

Number of Samples:	21
Number of Exceedances:	2

Data and Information Type:	PWS pathogen monitoring (ambient water)
Data Used to Assess Water Quality:	Beach monitoring data was collected by the County of San Diego from January 2004 through December 2007. A total of 228 single samples were collected with 21 samples correlated with a storm event. Two of the storm samples exceeded the single sample water quality objective.
Data Reference:	National Weather Service Forecast Office, San Diego, California, Chronological Regional Temperature and Precipitation Listings by Station
	Department of Environmental Health, Ocean & Bay Recreational Water Quality Program, 2007. AB 411 monitoring data 1999 to 2007.

Water Quality Objective/Criterion:	Single Sample Maximum: Enterococcus density shall not exceed 104 per 100 ml; Geomean: Enterococcus density shall not exceed 35 per 100 ml (SWRCB, 2005). Comparisons to water quality objectives were made for all data and data associated with storm events. A storm event was defined as 0.2 inches of rainfall within a 72 hour period.

Evaluation Guideline:
Guideline Reference:

Spatial Representation:	Samples were collected from the Mission San Diego HSA, at Ocean Beach on the north side of the pier at Newport Avenue, Station id PL-100. Lat/ Long: 32.749160/ -117.253000.
Temporal Representation:	Samples were collected weekly from January 2004 through December 2007.
Environmental Conditions:	Comparisons were made for all data and data associated with storm events. A storm event was defined as 0.2 inches of rainfall within a 72 hour period. 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.
QAPP Information:	Quality control for the bacteria analysis portion was conducted in accordance with the County of San Diego, Department Public Health Laboratory Quality Assurance Manual.
