| Pollutant: | Trash |
| Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL) |

| TMDL Name: | Santa Clara River Trash (36) |
| TMDL Project Code: | 383 |
| Date TMDL Approved by USEPA: | 02/27/2008 |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
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. One line of evidence is 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 a TMDL has 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 Decision Recommendation: | Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the Water Quality Limited Segments Being Addressed category of the section 303(d) list because a TMDL has been approved by USEPA, and applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |
| State Board Staff Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |
