Regional Board Staff Conclusion: This pollutant is being considered for removal from the section 303(d) list under section 4.1 of the Listing Policy. Under section 4.1 a single line of evidence is necessary to assess listing status.

One line of evidence is available in the administrative record to assess this pollutant. Two samples in one sampling station exceed the CTR Dissolved Cadmium Criterion for continuous concentration (CCC) in water for the protection of aquatic life.

The Los Angeles River Metals/Toxics TMDL was approved by the RWQCB in 2005 and subsequently approved by USEPA in 2005.

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.

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. Two out of 95 samples exceeded the dissolved cadmium continuous criterion concentration and this does not exceed the maximum allowable frequency listed in Table 4.1 of the Listing Policy.
4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met.
 
Regional Board Staff Decision Recommendation: This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current. The decision has not changed.

Regional Board Staff Conclusion: This pollutant is being considered for removal from the section 303(d) list under section 4 of the Listing Policy. Under this section of the Policy, a minimum of one line of evidence is needed to assess listing status.

The original line of evidence supporting the listing does not identify a pollutant but rather, a condition caused by a pollutant(s) (algal growth, foam, and odors).

The Los Angeles River Nitrogen TMDL was approved by RWQCB on August 19, 2003 and subsequently approved by USEPA on March 18, 2004. This TMDL will address this water body condition.

Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of removing this listing from the 303(d) Water Quality Limited Segment list because the segment pollutant combinations is not a pollutant.
 
Regional Board Staff Decision Recommendation: This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current. The decision has not changed.

Regional Board Staff 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 line of evidence is available in the administrative record to assess this pollutant. Three samples exceeded the CTR dissolved copper criterion for the protection of aquatic life.

The Los Angeles River Metals/Toxics TMDL was approved by the RWQCB in 2005 and subsequently approved by USEPA in 2005.

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 on the section 303(d) list in the Water Quality Limited Segments Being Addressed 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.Three of six samples exceeded the CTR dissolved copper criterion for continuous concentration in water and there is a TMDL in place to address this pollutant in this water body.
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 Staff Decision Recommendation: This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current. The decision has not changed.

Regional Board Staff 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 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 the samples exceeded the CTR dissolved lead criterion and this
does not exceed the allowable frequency listed in Table 3.1 of the Listing
Policy.
4.Pursuant to section 3.11 of the Listing Policy, no additional data and
information are available indicating that standards are not met.

The USEPA final decision for the 2006 303(d) list added this listing to the 'being addressed by USEPA approved TMDL' portion of the 303(d) List because the Los Angeles River Metals/Toxics TMDL was approved by USEPA on 12/22/2005 (USEPA, 2007).
 
Regional Board Staff Decision Recommendation: This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current. The decision has not changed.
