DECISION ID	77703	Region 9
Pacific Ocean Shoreline, San Luis Rey HU, Oceanside Pier at Pier View Way

Pollutant:	Indicator Bacteria
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(2016)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.2 of the Listing Policy. Under section 3.2 a single line of evidence is necessary to assess listing status. Fourteen lines of evidence are available in the administrative record to assess this pollutant. With the latest data, four of 81 geomean samples exceed the water quality objective for enterococcus for the protection of REC-1. 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. With the latest data, four of 81 geomean samples exceed the water quality objective for enterococcus for the protection of REC-1 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 because applicable water quality standards are not being exceeded.

State Board Review of Regional Board Conclusion and Recommendation:

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

Data Used to Assess Water Quality:

Beach monitoring data was collected by the County of San Diego from February 2004 through December 2007. A total of 173 single samples were collected with ten samples correlating with a storm event. One of the ten samples exceeded the single sample water quality objective. In 2006, ¿Pacific Ocean Shoreline, San Luis Rey HU¿ was listed for Indicator Bacteria. This information will not be used in determining a listing decision, but is of interest to the Regional Board and has been included here as additional anecdotal information.

Samples were collected at Oceanside Pier (at Pier View Way), San Diego, California. Department of Environmental Health identification number is OC-080.

Temporal Representation:

Samples were collected from February 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.

Beach monitoring data was collected by the County of San Diego from January 2004 through December 2007. A total of 173 single samples were collected with 12 samples exceeded the single sample water quality objective.

Data Reference:

Department of Environmental Health, Ocean & Bay Recreational Water Quality Program, 2007. AB 411 monitoring data 1999 to 2007

SWAMP Data:

Non-SWAMP

Water Quality Objective/Criterion:

From the Ocean Plan the median coliform density shall not exceed 70 per 100ml, and not more than 10 percent of the samples shall exceed 230 per 100ml (SWRCB, 2005). Comparisons were also made for days with matching bacteria and storm event data. A storm event was defined as 0.2 inches of rainfall within a 72 hour period. In 2006, ¿Pacific Ocean Shoreline, San Luis Rey HU¿ was listed for Indicator Bacteria. For 2008, the 2006 San Luis Rey HU segment has been split into smaller segments and each represents an area near the sampling location of the data being assessed. ¿Pacific Ocean Shoreline, San Luis Rey HU, Oceanside Pier at Pier View Way' is one of the sampling locations for Pacific Ocean Shoreline, San Luis Rey HU, 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 total coliform, fecal coliform, and enterococcus, for removal or non-removal from the 303(d) list.

DECISION ID	84253	Region 9
Pacific Ocean Shoreline, San Luis Rey HU, Oceanside Pier at Pier View Way

Pollutant:	Trash
Final Listing Decision:	List on 303(d) list (being addressed by action other than TMDL)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (being addressed by action other than TMDL)(2016)
Revision Status	Original
Sources:	A Source Unknown
Expected Attainment Date:	2029
Implementation Action Other than TMDL:	Collected effort of public, agencies, organizations, and permittees. Methods include street sweeping, education programs on littering, installation of trash-catching devices on storm drains.
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under section 3.7 of the Listing Policy. Under this section when all other listing factors do not result in the listing of a water segment but information indicates non-attainment of standards, a water segment shall be evaluated to determine whether the weight of evidence demonstrates that water quality standard is not attained. If the weight of evidence indicates non-attainment, the water segment shall be placed on the CWA section 303(d) List. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination from 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 following information indicates that the water quality standard is not being attained: Coastkeeper cleanups occurred on 5/12/07, 3/8/08, 3/14/09 and 3/13/10 for this water body. The total weight of trash (lbs) collected on these dates was 1,147.25. Using the metric, Coastkeeper classified this water body as medium for trash impairment. However, any trash found is an exceedance and needs to be addressed by an action other than a TMDL. 3. This process is scientifically defensible and reproducible.

Regional Board Decision Recommendation:	After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem.

State Board Review of Regional Board Conclusion and Recommendation:

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