Regional Board 4 - Los Angeles Region

Water Body Name:	Promenade Park Beach
Water Body ID:	CAX4021000020021007125121
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	75700	Region 4
Promenade Park Beach

Pollutant:	Indicator Bacteria
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Delist from 303(d) list (TMDL required list)(2016)
Revision Status	Revised
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 3.3 of the Listing Policy. Under this section a single line of evidence is necessary to assess listing status. 29 lines of evidence are available in the administrative record to assess this pollutant. Use of data assessed against the shellfish standard is inappropriate at this time and will not be considered in final decision. Only 12 lines of evidence will be used for the final decision because those lines of evidence already include all the data used from the other lines of evidence. 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. 172 of 2374, 5 of 2031, and 47 of 2527 samples exceeded the OBJECTIVES 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.
