| Regional Board Conclusion: |
Insufficient information is available to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. Beneficial use support will be reassessed in a future cycle, if more data are available |
| |
| Regional Board Decision Recommendation: |
After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| State Board Review of Regional Board Conclusion and Recommendation: |
|
| |
| State Board Decision Recommendation: |
After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because it cannot be determined if applicable water quality standards are not being exceeded. |

| Data and Information Type: |
PHYSICAL/CHEMICAL MONITORING |
| Data Used to Assess Water Quality: |
Water Board staff assessed SWAMP BDAT data for Live Oak Laterals 1 & 2 (Sutter County) to determine beneficial use support and results are as follows: 0 of 3 samples exceeded the upper limit of the range for SpecificConductivity. Additionally, 0 of the 3 samples fall within the range, and 3 of 3 samples fall below the threshold. |

| Spatial Representation: |
The samples were collected at 1 monitoring site: 520LSAC15 (RD777 @ Paseo Ave.). |
| Temporal Representation: |
The samples were collected between the dates of 2000-12-07 and 2002-07-30 |
| Environmental Conditions: |

| QAPP Information: |
Monitoring was conducted in accordance with the State Water Resources Control Board's Quality Assurance Program Plan for the State of California's Surface Water Ambient Monitoring Program. |
| QAPP Information Reference(s): |
This is a placeholder for previously assessed data that does not have quality assurance information but would require it under newly developed policies. These LOEs were previously assessed and approved at the Regional, State and Federal level in past cycles. The LOEs needed to be moved and/or reassessed but required this reference code for movement within the decision making database. |
