## Regional Board 3 - Central Coast Region

Water Body Name: | Carpinteria Marsh (El Estero Marsh)
Water Body ID: | CAE3153402019980827165144
Water Body Type: | Estuary

DECISION ID | 5420
Pollutant: | Sedimentation/Siltation
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)(2006)
Revision Status | Original
Reason for Delisting: | Other
Impairment from Pollutant or Pollution: | Pollutant
Weight of Evidence: | This pollutant is being considered for removal from the section 303(d) list under section 4 of the Listing Policy. The Policy calls for the delisting of waters if the decision is found to be based on faulty data and it is demonstrated that the listing would not have occurred in the absence of such faulty data. One line of evidence is available in the administrative record to assess this pollutant. The data cannot be found that was used to list this pollutant. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for maintaining the listing for this water segment-pollutant combination. This conclusion is based on the staff findings that no data is available to assess the status of this water body for this pollutant. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met.
RWQCB Board Decision / Staff Recommendation: | No new data were assessed for 2008. The decision has not changed.
SWRCB Board Decision / Staff Recommendation: | After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should be removed from the section 303(d) list because no data are available to support the listing.

Data Used to Assess Water Quality: | Carpinteria Marsh was originally listed on the section 303(d) list because Regional Board staff observed erosion and sedimentation in the 1980s. This listing basis is faulty because it is not based on any data. Regional Board staff is not aware of evidence to indicate current water quality standard exceedances or beneficial use impacts related to the listing for this pollutant.
