DECISION ID	43763	Region 9
Pacific Ocean Shoreline, Dana Point HSA, at Dana Point Harbor at Baby 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:	Do Not Delist from 303(d) list (TMDL required list)(2012)
Revision Status	Revised
Sources:	See TMDL documentation \| Surface Runoff
TMDL Name:	Bacteria TMDL for San Diego Bay and Dana Point Harbor Shorelines
TMDL Project Code:	659
Date TMDL Approved by USEPA:	10/26/2009
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. Seven 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. 176 of 571 samples exceed the SSM objective for total coliform (for SHELL) and these exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. The Bacteria TMDL for baby beach and shelter island was approved by USEPA on 10/26/2009. 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.

Data Used to Assess Water Quality:

For the period from January 2000 to December 2006, there were 4433 beach postings days for all of Dana Point Harbor. When a bacteriological sample exceeds water quality standards, signs are posted indicating that waters have exceeded public health standards.

Data and information on the number of beach posting were summarized by the County of Orange in their Annual Ocean and Bay Water Quality Report, March 2007. The reporting period was from January 2000 -December 2006. Data used was the number of days the beach was posting when the ocean or bay failed to meet the bacteriological standards.
