| Regional Board Conclusion: | This pollutant is being considered for placement on the section 303(d) list under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status.
One (1) line of evidence is available in the administrative record to assess this pollutant. None of the samples exceed the water quality objective. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. None of one sample exceeded the USEPA National Recommended Ambient Water Quality Criteria Aquatic Life Protection Instantaneous Maximum and this sample size is insufficient to determine with the power and confidence of the Listing Policy if standards are not met. A minimum of two samples are needed for application of table 3.1. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. |
| 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 because it cannot be determined if applicable water quality standards are not being exceeded. |

| Regional Board Conclusion: | 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. This water body's original listing was for Chino Creek Reach 1. The Regional Board, via a basin plan amendment, split reach 1 into reach 1A and 1B. This decision is a continuation of the listing for Chino Creek Reach 1. State Board Review and Conclusion: This decision above to continue listing this previously listed water body for nutrients was made by the Santa Ana Regional Board staff in the centralized database. However, the centralized database was not used to generate the final Staff Report for Region 8 and the decision didn't get included for the Regional Water Board for approval. Based on the review of the data and information in the centralized database, State Water Board staff recommends to continue to List this water body-pollutant combination. |
| Regional Board Decision Recommendation: | No new data were assessed for 2008. The decision has not changed. |
| 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. |
| USEPA Action (if applicable): | USEPA approved the listing of this water body as a water quality limited segment requiring a TMDL for this pollutant. |

| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | Regional Board Conclusion:
This pollutant is being considered for listing under section 2.2 of the Listing Policy. Under this section of the Policy, a minimum of one line of evidence is needed to assess listing status. The Prado Area Streams Pathogen TMDL was approved by the RWQCB in 2007 and subsequently approved by USEPA on 5/16/07. Based on the readily available information, the weight of evidence indicates that there is sufficient justification in favor of placing this water segment-pollutant combination in the Water Quality Limited Segments Being Addressed portion of the section 303(d) list. The original listing was for Chino Creek Reach 1. The Regional Board split reach 1 into reach 1A and 1B via a basin plan amendment. This is a continuation of the original listing for Reach 1. State Board Review and Conclusion: This decision above to continue listing this previously listed water body for pathogens on the being addressed list was made by the Santa Ana Regional Board staff in the centralized database. However, the centralized database was not used to generate the final Staff Report for Region 8 and the decision didn't get included for the Regional Water Board for approval. Based on the review of the data and information in the centralized database, State Water Board staff recommends to continue to List this water body-pollutant combination. |
| Regional Board Decision Recommendation: | No new data were assessed for 2008. The decision has not changed. |
| State Board Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | This listing was accidentally removed from the being addressed part of the 303(d) list. No new data were assessed for 2008 and SWRCB staff conclude that the water body should be placed back on the Water Quality Limited Segments Being Addressed part of the 303(d) list because a TMDL has been approved by USEPA and an implementation plan has been approved. |
