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.

One line of evidence is available in the administrative record to assess this pollutant. Based on the applicable factor, a TMDL and implementation plan has been approved for this water segment-pollutant combination. The Indian Creek Reservoir Phosphorus TMDL was approved by RWQCB on July 24, 2002 and subsequently approved by USEPA on July 1, 2003. The approved TMDL and implementation plan is expected to result in attainment of the standard.

Based on the readily available data and 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.
