Regional Board Conclusion: |
Region 3 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. |
|
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. |

State Board Decision Recommendation: |
After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |

Spatial Representation: |
Data for this line of evidence for Santa Maria River Estuary was collected from a single CCAMP monitoring site (312SMA- Santa Maria River above the estuary). This monitoring site is approximately 300 m upstream of the estuary. However, there are no tributaries or other inputs between this monitoring site and the estuary. |
Temporal Representation: |
Data was collected over the time period 1/12/00 - 12/6/06. CCAMP staff conducted monitoring monthly at this site with the exception of April 2003-December 2003. |
