Regional Board 4 - Los Angeles Region

Water Body Name:	Venice Beach
Water Body ID:	CAX4051300019990924084731
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	32952	Region 4
Venice Beach

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:	List on 303(d) list (being addressed by USEPA approved TMDL)(2012)
Revision Status	Revised
Sources:	Nonpoint Source
TMDL Name:	Santa Monica Bay Beach Closures/Coliform/Bacteria Indicators (48)
TMDL Project Code:	392
Date TMDL Approved by USEPA:	06/19/2003
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Staff Conclusion:	This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and 4.3 of the Listing Policy. Under SECTION 4.3 of the Policy, a minimum of one line of evidence is needed to assess listing status. 17 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. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 871 of 4472 and 353 of 1161 samples exceeded the OBJECTIVE and these exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. The Santa Monica Bay Beach Closures/Coliform/Bacteria Indicators was approved by USEPA on 06/19/2003. 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 Staff 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.

Data Used to Assess Water Quality:

The most conservative applicable water quality criterion for total coliform is 70 MPN/100mL for the Basin Plan SHELL 30-Day Median objective. In Venice Beach, the criterion was exceeded in 696 of 1690 samples, which is 41.2% of the sample events. Under the state's Listing Policy, a water body is considered to be impaired for total coliform if there are 281 or more exceedances out of the 1690 samples. The most conservative applicable water quality criterion for fecal coliform is 200 MPN/100mL for the Basin Plan REC-1 Marine 30-Day Minimum 5 samples objective. In Venice Beach, the criterion was exceeded in 1 of 1701 samples, which is 0.1% of the sample events. Under the state's Listing Policy, a water body is eligible for delisting for fecal coliform if there are 282 or fewer exceedances out of the 1701 samples. The most conservative applicable water quality criterion for enterococcus is 35 MPN/100mL for the Basin Plan REC-1 Marine 30-Day Minimum 5 samples objective. In Venice Beach, the criterion was exceeded in 174 of 1081 samples, which is 16.1% of the sample events. Under the state's Listing Policy, a water body is eligible for delisting for enterococcus if there are 179 or fewer exceedances out of the 1081 samples (City of Los Angeles, Bureau of Sanitation, 2006).
