| TMDL Name: | Santa Monica Bay Historic Pesticides (58) |
| TMDL Project Code: | 397 |
| Date TMDL Approved by USEPA: | 03/26/2012 |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Staff Conclusion: | 303(d) listing decisions made prior to 2006 were not held in an assessment database.
There is sufficient justification to place waterbody/pollutant in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by USEPA, and is expected to result in attainment of the standard. This conclusion is based on the staff findings that: 1. The Santa Monica Bay DDT and PCB TMDL was approved by USEPA on 03/26/2012. |
| Regional Board Staff 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. |

| Revision Status | Original |
| Sources: | Major Municipal Point Source-dry and/or wet weather discharge |
| TMDL Name: | Santa Monica Bay Beach Closures/Coliform/Bacteria Indicators (48) |
| TMDL Project Code: | 392 |
| Date TMDL Approved by USEPA: | 06/19/2003 |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Staff Conclusion: | This pollutant is being considered for removal on the section 303(d) list under sections 2.2 of the Listing Policy. Under 2.2 of the Policy, a minimum of one line of evidence is needed to assess listing status.
Two 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 section 303(d) list. There is sufficient justification to place it in the Being Addressed portion of the 303(d) list because TMDLs have been completed and adopted by the Los Angeles RWQCB and approved by USEPA, and is expected to result in attainment of the standard. |
| Regional Board Staff Decision Recommendation: | This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current cycle. The decision has not changed. |
