Regional Board 4 - Los Angeles Region

Water Body Name:	Hueneme Beach Park
Water Body ID:	CAC4031100020090226105034
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	75276	Region 4
Hueneme Beach Park

Pollutant:	Indicator Bacteria
Final Listing Decision:	Do Not Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (TMDL required list)(2016)
Revision Status	Revised
Sources:	A Source Unknown
Expected TMDL Completion Date:	2023
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for removal from the CWA section 303(d) List under section 4.3 of the Listing Policy. Under this section a single line of evidence is necessary to assess listing status. 12 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 be not be considered in the final decision. Only 3 lines of evidence will be considered, 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 for removing 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 data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 38 of 736, 0 of 704, and 9 of 784 samples exceeded the OBJECTIVE and this does not exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met. State Board has reviewed this Decision, and has determined that the Listing still applies. The total coliform Shellfish objective is under review, but still applies under the Ocean Plan.

Regional Board Decision Recommendation:	After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be removed from the section 303(d) list because applicable water quality standards for the pollutant 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 following changes to the decision: 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.
