Regional Board 4 - Los Angeles Region

Water Body Name:	Los Angeles/Long Beach Outer Harbor (inside breakwater)
Water Body ID:	CAB4051800020050208092107
Water Body Type:	Bay & Harbor


DECISION ID	19086	Region 4
Los Angeles/Long Beach Outer Harbor (inside breakwater)

Pollutant:	PAHs (Polycyclic Aromatic Hydrocarbons)
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)(2010)
Revision Status	Original
Reason for Delisting:	Applicable WQS attained; reason for recovery unspecified
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. This pollutant is being considered for removal from the section 303(d) list under section 4.6 of the Listing Policy. Under section 4.6 a single line of evidence is necessary to assess listing status. Two lines of evidence are available in the administrative record to assess this pollutant. The site exhibits significant sediment toxicity but the pollutant is not likely to cause or contribute to the toxic effect. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for removing 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 sediment quality guideline used complies with the requirements of section 6.1.3 of the Policy. 2. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 3. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 4. None of the sediment samples exceeded the sediment quality guideline and this does not exceed the allowable frequency listed in Table 4.1 of the Listing Policy. 5. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

Regional Board Decision Recommendation:	Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

State Board Staff Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. This pollutant is being considered for removal from the section 303(d) list under section 4.1, 4.4, 4.5, and 4.11 of the Listing Policy. Four lines of evidence are available in the administrative record to assess this pollutant. Based on section 4.6 the site has significant sediment toxicity but it is unknown if the pollutant is not likely to cause or contribute to the toxic effect because no sediment guideline is available. An OEHHA advisory has been issued for the location and tissue samples show levels exceeding tissue guidelines. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. The tissue quality guideline used complies with the requirements of section 6.1.3 of the Policy. 2. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 3. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 4. Four of 13 samples exceeded the tissue guideline and a health advisory has been issued. 5. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met.

This pollutant is being considered for delisting under sections 4.4 of the Listing Policy. Under section 4.4 two lines of evidence are necessary to assess listing status. Two lines of evidence are available in the administrative record to assess this pollutant. Based on section 4.4, a health advisory has been issued for this water segment and mussel watch data exceed the tissue guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that: 1. The sediment quality guideline used complies with the requirements of section 6.1.3 of the Policy. 2. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 3. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 4.

Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. This pollutant is being considered for placement on the section 303(d) list under section 3.6 of the Listing Policy. Under section 3.6 at least one line of evidence is necessary to assess listing status. Two line of evidence is available in the administrative record to assess this pollutant. None of the samples exceeded an applicable sediment guideline and this pollutant is probably not responsible for the observed toxicity. 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. No exceedances of the guideline were observed. 4.

DECISION ID	19517	Region 4
Los Angeles/Long Beach Outer Harbor (inside breakwater)

Pollutant:	Zinc
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(2010)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. This pollutant is being considered for placement on the section 303(d) list under sections 2.1 and 3.6 of the Listing Policy. Under section 3.6 a single line of evidence is necessary to assess listing status. Two lines of evidence are available in the administrative record to assess this pollutant. Based on section 3.6 the site has significant sediment toxicity but the pollutant is not likely to cause or contribute to the toxic effect. 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 sediment quality guideline used complies with the requirements of section 6.1.3 of the Policy. 2. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 3. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 4. One of 75 samples exceeded the sediment guideline, and this does not exceed the allowable frequency listed in Table 3.1 of the Listing Policy. 5. Nine of 37 samples exhibit toxicity which exceeds the allowable limit in Table 3.1; however, there is no correlation that zinc is responsible for the toxicity. 6. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.
