DECISION ID	170410	Region 3
Pacific Ocean Shoreline at Refugio Beach (Santa Barbara County)

Pollutant:	Fecal Coliform
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)(2018)
Revision Status	Revised
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This 2026 decision corrects an error than occurred during the 2020-2022 cycle. Station WP0000183 was erroneously associated with Pacific Ocean at Arroyo Quemada Beach (Santa Barbara County) during the 2020-2022 cycle. This station should have been associated with Pacific Ocean at Refugio Beach (Santa Barbara County). This decision correctly associates site WP0000183 with Pacific Ocean at Refugio Beach (Santa Barbara County). The decision to not list remains the same for Pacific Ocean at Refugio Beach (Santa Barbara County) and Pacific Ocean at Arroyo Quemada Beach (Santa Barbara County). 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 fecal coliform objective. A total of six lines of evidence of fecal coliform data were evaluated for this waterbody. Of these lines of evidence, four are based on historic fecal coliform data collected prior to 2010. It should be noted that some of these historic data are E. coli results that are evaluated using the Ocean Plan Objective for Fecal Coliform. This objective is higher than the USEPA recreation criteria for E. coli. Evaluation of the data using the Fecal Coliform Objective could result in an erroneous decision to remove the beach segment from the 303(d) List and are not used here as the basis of a decision. Two lines of evidence are based on recent fecal coliform data, collected since 2010, and compared to the fecal coliform 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 four 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, 1 of 42 geometric means for fecal coliform calculated from 2015-2019 exceed the fecal coliform 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 not sufficient to place this waterbody on the 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 not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.

DECISION ID	170416	Region 3
Pacific Ocean Shoreline at Refugio Beach (Santa Barbara County)

Pollutant:	Enterococcus
Final Listing Decision:	List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Delist from 303(d) list (TMDL required list)(2018)
Revision Status	Revised
Sources:	No Source Analysis Available
TMDL Priority:	Low
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This 2026 decision corrects an error than occurred during the 2020-2022 cycle. Station WP0000183 was erroneously associated with Pacific Ocean at Arroyo Quemada Beach (Santa Barbara County) during the 2020-2022 cycle. This station should have been associated with Pacific Ocean at Refugio Beach (Santa Barbara County). This decision correctly associates site WP0000183 with Pacific Ocean at Refugio Beach (Santa Barbara County). This results in a listing for Pacific Ocean at Refugio Beach (Santa Barbara County) and a delisting for Pacific Ocean at Arroyo Quemada Beach (Santa Barbara County). 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 six lines of evidence of enterococci data were evaluated for this waterbody. Of these lines of evidence, four 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 2 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, 72 of 361 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.
