Regional Board 9 - San Diego Region

Water Body Name:	Pacific Ocean Shoreline, Batiquitos HSA, at Moonlight State Beach (Cottonwood Creek outlet)
Water Body ID:	CAC9045100020091026142908
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	43762	Region 9
Pacific Ocean Shoreline, Batiquitos HSA, at Moonlight State Beach (Cottonwood Creek outlet)

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
Sources:	Source Unknown
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 on the CWA section 303(d) List under sections 2.2 and [SECTION] of the Listing Policy. Under [SECTION] of the Policy, a minimum of one line of evidence is needed to assess listing status. Fifteen lines of evidence are available in the administrative record to assess this pollutant. 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 CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 3. With the latest data, 99 of 427 samples and 59 of 155 samples exceed the water quality objectives for total coliform of a single sample maximum of 230/100ml and of a geomean in a 30-day period of 70/100 ml, respectively, and these exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. The Bacteria TMDL for 20 beaches and creeks was approved by USEPA on 06/22/2011. 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 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:

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

Unspecified--This LOE is a placeholder to support a 303(d) listing decision made prior to 2006.

For the 2008 assessment , the 2006 listed coastline 'Pacific Ocean Shoreline, San Marcos HA' was renamed Batiquitos HSA and was split into smaller segments that each represent an area near the sampling location of the data being assessed. This segment 'Pacific Ocean Shoreline, Batiquitos HSA, at Moonlight State Beach (Cottonwood Creek outlet)' is one of the sampling locations. This LOE is a copy of the 2006 listing placeholder LOE for Pacific Ocean Shoreline, San Marcos HA and is considered by the Regional Board to be applicable to this more specific segment formed from the split.

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.

Data Used to Assess Water Quality:

For the period from January 2001 to December 2007, there were and 78 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.

DECISION ID	49675	Region 9
Pacific Ocean Shoreline, Batiquitos HSA, at Moonlight State Beach (Cottonwood Creek outlet)

Pollutant:	Trash
Final Listing Decision:	List on 303(d) list (being addressed by action other than TMDL)
Last Listing Cycle's Final Listing Decision:	New Decision
Revision Status	Revised
Sources:	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 1/13/07, 1/12/08, 1/10/09, 2/19/10, and 7/17/10 for this water body. The total weight of trash (lbs) collected on these dates was 1,143, using the metric, Coastkeeper classified this water body as high 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.

Coastkeeper cleanups occurred on 1/13/07, 1/12/08, 1/10/09, 2/19/10, and 7/17/10 for this water body. The total weight of trash (lbs) collected on these dates was 1,143.
