Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for removal on the section 303(d) list under section 4.1 and 4.6 of the Listing Policy. Under section 4.1 a single line of evidence is necessary to assess listing status. Three 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 14 of 48 samples exceeded the sediment quality guideline 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 2 samples exceeded the CTR criteria and 14 of 48 samples exceeded the sediment quality guideline. 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:	After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem.

State Board Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	After review of this Regional Board decision, SWRCB staff recommend the following changes to the decision: The water body-pollutant combination should not be removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded.

USEPA Action (if applicable):	USEPA approved the listing of this water body as a water quality limited segment requiring a TMDL for this pollutant.

DECISION ID	4087	Region 8
Newport Bay, Lower (entire lower bay, including Rhine Channel, Turning Basin and South Lido Channel to east end of H-J Moorings)

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:	List on 303(d) list (being addressed by USEPA approved TMDL)(2006)
Revision Status	Revised
Sources:	Source Unknown
TMDL Name:	Newport Bay Watershed Fecal Coliform TMDL
TMDL Project Code:	150
Date TMDL Approved by USEPA:	02/28/2000
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for removal on the section 303(d) list under sections 2.2 and 4.2 of the Listing Policy. Under 4.2 of the Policy, a minimum of one line of evidence is needed to assess listing status. Multiple lines of evidence are available in the administrative record to assess this pollutant. Each line of evidence is a station where samples had been collected. 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. There is sufficient justification to place it in the Being Addressed portion of the 303(d) list because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 4.2 of the Policy. 2. The data used satisfies the data quantity requirements of section 4.2 of the Policy. 3. Six hundred and sixty-six of 4646 samples exceeded the Ocean Plan Standard for enterococcus, total coliform, and fecal coliform and these exceed the allowable frequency listed in Table 3.2 of the Listing Policy. 4. The Total Maximum Daily Load for Fecal Coliform Bacteria in Newport Bay has been approved by the Santa Ana RWQCB in 1999 and approved by USEPA on 02/28/2000. 5. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. 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:	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 because applicable water quality standards for the pollutant are being exceeded.

State Board Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	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 because applicable water quality standards for the pollutant are being exceeded.

Regional Board 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. 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. Currently, Newport Bay, lower, 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.

Pollutant:	2-Methylnaphthalene \| Antimony \| Benzo(a)pyrene (3,4-Benzopyrene -7-d) \| Cadmium \| Chrysene (C1-C4) \| Endrin \| Lead \| PAHs (Polycyclic Aromatic Hydrocarbons) \| Pyrene \| Silver \| 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)(2006)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	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. Eleven pollutant specific lines of evidence are available in the administrative record to assess each pollutant. None of the evaluated pollutants exceeded pollutant specific sediment quality guidelines but sediment toxicity was documented in this water body. Currently, Newport Bay, lower, is listed for priority organics, pesticides and 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 organics, pesticides, and 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 insufficient justification for 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 11 pollutant specific lines of evidence exceeded sediment quality guidelines but sediment toxicity has been documented in this water body. 4. 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:	No new data were assessed for 2008. The decision has not changed.

DECISION ID	4395	Region 8
Newport Bay, Lower (entire lower bay, including Rhine Channel, Turning Basin and South Lido Channel to east end of H-J Moorings)

Pollutant:	Arsenic
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)(2006)
Revision Status	Original
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	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, lower, 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. Two lines of evidence are available in the administrative record to assess this pollutant. None of the samples exceeded the USEPA screening value and sediment quality guideline. 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 74 fish tissue samples exceeded the screening value, and none of the sediment samples exceeded the sediment quality guideline. Ten additional fish tissue samples analyzed for inorganic arsenic concentrations (ranged from 0.003 mg/kg to 0.020 mg/kg) were also found to be below the USEPA guideline 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.

Regional Board Decision Recommendation:	No new data were assessed for 2008. The decision has not changed.

Evaluation Guideline:

An applicable tissue screening value is not available for total arsenic in tissue. Analytical measurements reported as total arsenic do not provide a viable means of assessing arsenic in tissue for the protection of human health. The screening value of 1.2 ppm wet weight for inorganic arsenic is considered the most reliable risk-based screening value when compared with inorganic arsenic or as a percentage of total arsenic when inorganic arsenic data is not available. To be conservative and consistent with other agencies, USEPA finds acceptable to assume that inorganic arsenic comprises 10 percent of total arsenic for finfish and 60 percent of total arsenic in shellfish tissue.

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. Three lines of evidence (one for pollutant in tissue, one for pollutant in sediment, and one for sediment toxicity) available in the administrative record to assess this pollutant. None of the tissue samples exceeded the OEHHA screening value and none of three sediment samples collected exceeded PEL guidelines. Sediment toxicity has been documented within in this water body. 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 and sediment data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The tissue and sediment data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3.

Revision Status	Original
Sources:	Source Unknown
Expected TMDL Completion Date:	2019
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the section 303(d) list under sections 3.5 and 3.6 of the Listing Policy. Under sections 3.5 and 3.6 a single line of evidence is necessary to assess listing status. Currently, Newport Bay, lower, is listed for pesticides. It is not possible, in a general listing, to determine which specific pesticide could be 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 pesticides when found to be exceeding. Four lines of evidence are available in the administrative record to assess this pollutant. Enough samples exceeded the sediment guideline and exhibited toxicity. 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 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 51 tissue samples taken exceed the chlordane screening value, and 8 of 11 sediment samples exceed the sediment guideline, and 15 of 22 sediment samples exhibited toxicity and 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.

Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the section 303(d) list under sections 3.5 and 3.6 of the Listing Policy. Multiple lines of evidence are available in the administrative record to assess this pollutant. A sufficient number of tissue samples exceed the OEHHA screening value. Toxicity has been documented in sediment and there is significant biological community degradation in the water segment. However, it is not possible to determine exceedances of sediment samples because there are no applicable sediment quality guidelines for DDT. Currently, Newport Bay, lower, is listed for pesticides. It is not possible, in a general listing, to determine which specific pesticide could be causing or contributing to water quality impacts. There is sufficient justification for removing the general listing for pesticides from the 303(d) list and replacing it with the specific pesticides, 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 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 measurements used satisfy the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfy the data quantity requirements of section 6.1.5 of the Policy. 3. Eighteen of 56 tissue samples exceed the OEHHA screening value which exceeds the allowable frequency listed in Table 3.1 of the Listing Policy. There is significant sediment toxicity and biological community degradation documented. Exceedances in sediment samples cannot be determined because there is no applicable sediment quality guideline for 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.
