Regional Board 8 - Santa Ana Region

Water Body Name:	Newport Bay, Upper (Ecological Reserve)
Water Body ID:	CAE8011400019990323090803
Water Body Type:	Estuary


DECISION ID	18064	Region 8
Newport Bay, Upper (Ecological Reserve)

Pollutant:	Indicator Bacteria
Final Listing Decision:	Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL)
Last Listing Cycle's Final Listing Decision:	Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL)(2010)
Revision Status	Original
Sources:	Source Unknown
TMDL Name:	Newport Bay Watershed Fecal Coliform TMDL
TMDL Project Code:	150
Date TMDL Approved by USEPA:	01/01/2000
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 8 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 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 Newport Bay Watershed Fecal Coliform TMDL was completed in 2000. This water segment-pollutant combination was moved off the section 303(d) list during the 2002 listing cycle. 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. Please note that indicator bacteria was previously called pathogens.

Regional Board Decision Recommendation:	Region 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be removed from the section 303(d) list (being addressed by a US EPA approved TMDL) because applicable water quality standards for the pollutant are being exceeded.

State Board Staff Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	Region 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should not be removed from the section 303(d) list being addressed by a USEPA approved TMDL) because applicable water quality standards for the pollutant are being exceeded.

Pollutant:	2-Methylnaphthalene \| Antimony \| Benzo(a)pyrene (3,4-Benzopyrene -7-d) \| Chrysene (C1-C4) \| Dieldrin \| Endrin \| PAHs (Polycyclic Aromatic Hydrocarbons) \| Phenanthrene \| Pyrene \| Silver
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 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. These pollutants are being considered for placement on the section 303(d) list under section 3.6 of the Listing Policy. Under section 3.6 two lines of evidence are necessary to assess listing status. Currently, Newport Bay, Upper, is listed for priority organics, pesticides and metals (approximately 120 on the current USEPA priority pollutant list). It is not possible in a general listing to determine which specific pollutant is causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for organics, pesticides, and metals from the 303(d) list and replace these general listings with the specific pollutants found to be exceeding. Eleven lines of evidence are available in the administrative record to assess each pollutant. None of the evaluated pollutants exceeded pollutant specific sediment quality guidelines. Although sediment toxicity has been documented in this water body, it cannot be associated with any of these pollutants. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification in favor of placing these specific priority pollutants on 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. None of 9 lines of evidence exceeded sediment quality guidelines for these pollutants. Therefore, a link between the sediment toxicity in this waterbody and these pollutants cannot be made. 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:	Region 8 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 8 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.

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 8 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 3.5 of the Listing Policy. Under section 3.5 a single line of evidence is necessary to assess listing status. Currently, Newport Bay, upper, is listed for metals. It is not possible, in a general listing, to determine which specific metal could be causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for metals from the 303(d) list and replace these general listings with the specific metals when found to be exceeding. Five lines of evidence are available in the administrative record to assess this pollutant. None of the samples exceed the USEPA screening value of 1.2 mg/kg for the protection of human health. 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 23 fish tissue total arsenic samples exceeded the USEPA screening value and there were also no exceedances in three additional fish tissue inorganic arsenic samples as well. Sediment and water samples did not exceed the applicable sediment and CTR water column guidelines and this does not exceed the allowable frequency listed in Table 3.1 of the Listing Policy. Although sediment toxicity has been documented in this water body, it cannot be associated with this pollutant. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

DECISION ID	19299	Region 8
Newport Bay, Upper (Ecological Reserve)

Pollutant:	Cadmium
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 8 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 3.1 and 3.5 of the Listing Policy. Under section 3.1 and 3.5 a single line of evidence is necessary to assess listing status. Currently, Newport Bay, Upper, is listed for metals. It is not possible, in a general listing, to determine which specific metal is causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for metals from the 303(d) list and replace these general listings with the specific metals when found to be exceeding. 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 from the section 303(d) list. This conclusion is based on the staff findings that: 1. The tissue, water column, and sediment data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The tissue, water column, and sediment data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. None of tissue samples taken exceed the cadmium 3 ppm wet weight OEHHA screening value (OEHHA, 1999) none of 3 water column samples exceeded the cadmium CTR saltwater chronic criteria, and none of two samples exceeded the PEL sediment quality guideline. These samples do 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.

Regional Board Decision Recommendation:	Region 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

DECISION ID	18621	Region 8
Newport Bay, Upper (Ecological Reserve)

Pollutant:	Nickel
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 8 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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Currently, Newport Bay, upper, is listed for metals. It is not possible, in a general listing, to determine which specific metal could be causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for metals from the 303(d) list and replace these general listings with the specific metals when found to be exceeding. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of not placing this water segment-pollutant combination on 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. None of the 3 samples exceeded the CTR saltwater chronic water quality objective and this does not exceed the allowable frequency listed in Table 4.1 of the Listing Policy. Although sediment toxicity has been documented in this water body, it cannot be associated with this pollutant since there is no applicable guideline available for evaluating this pollutant in sediment. 3. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met.

Regional Board Decision Recommendation:	Region 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

Currently, Newport Bay is listed for metals. It is not possible, in a general listing, to determine which specific pollutant is causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for metals from the 303(d) list and replace these general listings with the specific pollutants when found to be exceeding. 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 does not satisfy the temporial and spatial data quantity requirements of section 6.1.5 of the Policy. 3. None of the 3 samples exceeded the CTR saltwater chronic criteria and none of the 2 exceeded the PEL sediment quality guideline. This does not exceed the allowable frequency listed in Table 3.1 of the Listing Policy. Although sediment toxicity has been documented in this water body, it cannot be associated with this pollutant. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are met.

Regional Board Conclusion:	Region 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. These pollutants are being considered for listing under sections 3.1 and 3.6 of the Listing Policy. Under sections 3.1 and 3.6 a single line of evidence is necessary to assess listing status. Currently, Newport Bay, Upper, is listed for pesticides. It is not possible, in a general listing, to determine which specific pollutant is causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for pesticides from the 303(d) list and replace these general listings with the specific pollutants when found to be exceeding. Sediment toxicity has been documented in this water body, and enough sediment samples exceed the guideline. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination on the section 303(d) list. This conclusion is based on the staff findings that: 1. The water and sediment data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The water and sediment data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. Three of the 11 sediment samples exceed the sediment quality guideline. And a large number of sediment samples exhibit sediment toxicity in this water body. This exceeds 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.

Regional Board Conclusion:	Region 8 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 3.1 of the Listing Policy. Under section 3.1 one line of evidence is necessary to assess listing status. Five lines of evidence are available in the administrative record to assess this pollutant. A sufficient number of samples exceed the CTR criteria. Sediment toxicity has been documented, and none of the sediment samples exceeded the sediment quality guideline for copper in this water body. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for 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. Two of 6 water samples exceeded the CTR criteria. Sediment toxicity has been documented, but none of the sediment samples exceeded the sediment quality guideline for copper 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. Currently, Newport Bay, upper, is listed for metals. It is not possible in a general listing to determine which specific metal is causing or contributing to a water quality impacts. There is sufficient justification for removing the general listings for metals from the 303(d) list and replace these general listings with the specific metals found to be exceeding.

Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 8 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 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. 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 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. Eleven of 30 samples exceeded the 100 µg/kg (ppb) wet weight OEHHA screening value. For toxicity; 5 of 15 sediment samples were significantly toxic to amphipods. Fifteen of 15 pore water samples collected had significant effect in Purple Urchin larval development. One of 15 sediment water interface samples were was significantly toxic to Purple Sea Urchin. Five of 15 sediment water interface samples were significantly toxic to the fertilization test. For benthic degradation; 4 of 16 samples exhibited significant biological community degradation. Three samples were collected, however number of exceedances cannot be determined due to the unavailability of an applicable sediment quality guideline for total DDT. The tissue sample exceedances meet 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.

Regional Board Decision Recommendation:	Region 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

Final Listing Decision:	List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	List on 303(d) list (TMDL required list)(2010)
Revision Status	Original
Sources:	Source Unknown

Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 8 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. There are five lines of evidence available in the administrative record to assess this pollutant. 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 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. Four of 30 samples exceeded the OEHHA screening value and this does exceed the allowable frequency listed in Table 3.1 of the Listing Policy. Although sediment toxicity has been documented in this water body, none of 4 samples exceeded the dry weight sediment quality guideline. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are met.

Regional Board Decision Recommendation:	Region 8 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 8 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle. After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards for the pollutant are exceeded.
