Castro Cove, Richmond (San Pablo Basin) |
||
| Pollutant: | Dieldrin (sediment) |
| Final Listing Decision: | List on 303(d) list (being addressed by action other than TMDL) |
| Last Listing Cycle's Final Listing Decision: | List on 303(d) list (TMDL required list)(2006) |
| Revision Status | Revised |
| Sources: | Point Source | Urban Runoff/Storm Sewers |
| Expected Attainment Date: | 2010 |
| Implementation Action Other than TMDL: | Regional Board has issued a cleanup and abatement order (Order No. R2-2006-0078) requiring remediation of sediment contamination in the listed portion of Castro Cove. Cleanup is underway and upon its completion it is expected that this water body will meet applicable water quality standards.
In November 2007, Regional Board received a Monitoring and Risk Management Plan which includes post-dredging confirmation monitoring to demonstrate that chemical contamination in the sediment has been reduced to levels that no longer pose unacceptable ecological risk. |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | 303(d) listing decisions made prior to 2006 were not held in an assessment database. The Regional Boards will update this decision when new data and information become available and are assessed. |
| Regional Board Decision Recommendation: | Water Board staff conclude that the water body should be placed in the category of the section 303(d) list being addressed by action other than a TMDL. The cleanup that is already taking place will result in reductions of pollutant concentrations to a level that achieves the numeric water quality standards and the proposed Monitoring and Risk Management Plan will demonstrate attainment of the standards. |
| 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. |
