Water Body Type:	Coastal & Bay Shoreline


DECISION ID	94138	Region 8
Huntington City Beach

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. Thirty Three (33) lines of evidence are available in the administrative record to assess this pollutant. One hundred and Forty Four (144) of 4156 samples exceed the Enterococcus Geomean Objective. Sixty One (61) of 1365 samples exceed the Enterococcus Single Sample Objective. Forty Five (45) of 4802 samples exceed the Fecal Coliform Geomean Objective. Eight (8) of 738 samples exceed the Fecal Coliform Single Sample Objective. Twenty Six (26) of 4167 samples exceed the Total Coliform Geomean Objective. Seven (7) of 1364 samples exceed the Total Coliform Single Sample Objective. 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. One hundred and Forty Four (144) of the 4156 samples exceed the Enterococcus Geomean Objective, 45 of the 4802 samples exceed the Fecal Coliform Geomean Objective, 26 of the 4167 samples exceed the Total Coliform Geomean, and this does not exceed the frequency listed in table 3.2 4. Sixty One (61) of the 1365 samples exceed the Enterococcus Single Sample Objective, Eight (8) of the 738 samples exceed the Fecal Coliform Single Sample Objective, Seven (7) of the 1364 samples exceed the Total Coliform Single Sample, and this does not exceed the frequency listed in table 3.2 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 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.
