San Jose Creek Reach 2 (Temple to I-10 at White Ave.) |

| Pollutant: | Excess Algal Growth |
| Final Listing Decision: | Delist from 303(d) list (TMDL required list) |
| Last Listing Cycle's Final Listing Decision: | Delist from 303(d) list (TMDL required list)(2006) |
| Revision Status | Original |
| Reason for Delisting: | Flaws in original listing |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | This condition is being considered for delisting under section 4.7 of the Listing Policy. Under this section 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. It is not known if the algae information is backed by pollutant data. Algae should not be placed on the section 303(d) list because it is not a pollutant or toxicity (section 2 of the Listing Policy). Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of removing this water segment-pollutant combination from the Section 303(d) list. |
| Regional Board Decision Recommendation: | 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. |

| Water Quality Objective/Criterion: | Basin Plan: Waters shall not contain biostimulatory substances in concentrations that promote aquatic growth to the extent that such growth causes nuisance or adversely affects beneficial uses. | ||||
| Objective/Criterion Reference: | Placeholder reference 2006 303(d) | ||||
| Evaluation Guideline: | The presence of algae in the water segment was used as the guideline. The rankings were subjective and assigned to water bodies by one person for consistency. | ||||
| Guideline Reference: | Placeholder reference 2006 303(d) | ||||
| Spatial Representation: | One sampling location. In 1996, San Jose Creek was defined as a single segment. When the segment was split the listing was applied to both segments. There is no assessment in Reach 2 as currently defined. | ||||
| Temporal Representation: | Observations made between 1990 and 1993. Samples taken in different seasons and 4 samples taken in 1992. | ||||
