DECISION ID	129316	Region 3
Pacific Ocean at Carpinteria State Beach (Carpinteria Creek mouth, Santa Barbara County)

Pollutant:	Enterococcus
Final Listing Decision:	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)(2018)
Revision Status	Revised
Sources:	No Source Analysis Available
Expected TMDL Completion Date:	2035
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	The Water Quality Control Plan for Ocean Waters (“Ocean Plan”) contains two bacteria water quality objectives applicable to the REC-1 beneficial use: a fecal coliform water quality objective and an enterococci water quality objective. This waterbody is being considered for placement on the CWA section 303(d) List under section 3.3 of the Listing Policy using the enterococci objective. A total of 8 lines of evidence of enterococci data were evaluated for this waterbody. Of these lines of evidence, 6 are based on historic enterococci data collected prior to 2010. Two lines of evidence are based on recent enterococci data, collected since 2010, and compared to the enterococci bacteria water quality objectives. In accordance with section 6.1.5.3 of the Listing Policy, to be evaluated to develop the list, the data should be representative of the critical timing that the pollutant is expected to impact the waterbody. Indicator bacteria (total coliform, fecal coliform, E. coli, enterococci) populations may fluctuate substantially on a daily, seasonal, or yearly basis. Lacking constant inputs, they do not persist in the environment for a long period and effects are of relatively short duration. As a result, the historic levels of indicator bacteria in the waterbody may be a poor indicator of current risks to human health, particularly when more recent data is available to sufficiently assess the water quality standard. Unrepresentative data will likely result in incorrectly placing or not placing a water body segment on the CWA section 303(d) List. This could result in the unnecessary expenditure of public resources or missing a problem completely. The 6 historic lines of evidence were evaluated pursuant to these considerations and were not used to assess water quality standards attainment because they do not meet the temporal representation requirements of section 6.1.5.3 of the Listing Policy. The recent data were collected during 2010-2019. There are adequate recent data to determine beneficial use support in accordance with the Listing Policy. The recent data are representative of existing conditions in the waterbody and represent a range of hydrologic conditions (both wet and dry years). With respect to the recent lines of evidence, 83 of 363 geometric means for enterococci calculated from 2010-2019 exceed the enterococci objective. For these data, Listing Policy section 3.3 instructs to use the binomial distribution table in section 3.2. Using the applicable exceedance frequency, the number of exceedances is sufficient to place this waterbody on the list. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification to add this waterbody to the 303(d) list. The data used satisfies the data quality requirements (section 6.1.4) and data quantity requirements (section 6.1.5) of the Listing Policy. 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 be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem.

State Board Review of Regional Board Conclusion and Recommendation:	.

State Board Decision Recommendation:	After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem.

DECISION ID	80648	Region 3
Pacific Ocean at Carpinteria State Beach (Carpinteria Creek mouth, Santa Barbara County)

Pollutant:	Total Coliform
Final Listing Decision:	Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Delist from 303(d) list (TMDL required list)(2016)
Revision Status	Original
Reason for Delisting:	Applicable WQS attained; reason for recovery unspecified
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for removal from the section 303(d) list under sections 4.2 and 4.3 of the Listing Policy. Under these sections, a single line of evidence is necessary to assess listing status. One lines of evidence are available in the administrative record to assess this pollutant. The data associated with the original listing (LOE 3980 - placeholder reference for assessments made prior to the 2006) is no longer available. However, the most recent six years of data show that the beneficial use is being fully supported. 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 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. None of these 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 not met.

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 decision be approved by the State Board.
