Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for removal from the CWA section 303(d) List under section 4.1 of the Listing Policy. Under this section a single line of evidence is necessary to assess listing status.

The Newport Bay Watershed Diazinon/Chlorpyrifos TMDL was approved by RWQCB on April 4, 2003 and subsequently approved by USEPA on February 13, 2004.

Three lines of evidence are available in the administrative record to assess this pollutant.
0 of 48 samples exceed the Criteria Continuous Concentration for Chlorpyrifos of 9 ng/L. However 43 samples had a detection limit higher than 9 ng/L rendering them unusable for assessment purposes.

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 from the CWA 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. 0 of 48 water samples exceeded the criteria continuous concentration in saltwater and this exceeds the 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 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 removed from the section 303(d) list because applicable water quality standards for the pollutant are not being exceeded.
 
State Board Review of Regional Board Conclusion and Recommendation:
 
State Board Decision Recommendation: After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Regional Board Conclusion: This pollutant is being considered for removal from the CWA section 303(d) List under section 4.1 of the Listing Policy. Under this section 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 found to be exceeding.

Four lines of evidence are available in the administrative record to assess this pollutant. Seven out of 94 samples exceed the CTR criteria and this does not exceed the allowable frequency listed in Table 4.1 of the Listing Policy.. Sediment toxicity has been documented, and none of the sediment samples exceeded the sediment quality guideline for copper in this water body.

Upper Newport Bay was dredged in 2010. For those areas that were dredged in 2010, a determination of impairment should not be made based on sediment data prior to 2011 since those sediments were removed from the Bay in 2010.

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 CWA section 303(d) List. This conclusion is based on the staff findings that:

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. Seven out of 94 water samples exceeded the CTR criteria and this does not exceed the allowable frequency listed in Table 4.1 of the Listing Policy. Sediment toxicity has been documented, but none of the sediment samples exceeded the sediment quality guideline for copper in this water body. Upper Newport Bay was dredged in 2010. For those areas that were dredged in 2010, a determination of impairment should not be made based on sediment data prior to 2011 since those sediments were removed from the Bay in 2010.
4. Pursuant to section 4.11 of the Listing Policy, additional data and information are available indicating that standards are not met.

5.The following information indicates that the water quality standard is not being attained:
Data not available for the current listing cycle process were evaluated and are available in the Attachment A to Resolution No. R8-2016-0059. Thirteen out of 27 water samples exceeded the CTR criteria (Coastkeeper 2007) and forty-eight out of 68 water samples exceeded the CTR criteria (Orange County 2009-2011). Two out of two stormwater samples exceeded the CTR criteria (Bay et al. 2004). The total number of exceedances out of the total number of samples (70/191) exceeds the allowable frequency listed in Table 4.1 of the Listing Policy.

6.This process is scientifically defensible and reproducible.
 
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.

There are additional data that are not included in this assessment that show standards are being exceeded. These data should be submitted to CEDEN as soon as possible and prioritized for assessment within the next assessment even if off-cycle for Region 8.
 
State Board Review of Regional Board Conclusion and Recommendation: 5.The following information indicates that the water quality standard is not being attained:
Data not available for the current listing cycle process were evaluated and are available in the Attachment A to Resolution No. R8-2016-0059. Thirteen out of 27 water samples exceeded the CTR criteria (Coastkeeper 2007) and forty-eight out of 68 water samples exceeded the CTR criteria (Orange County 2009-2011). Two out of two stormwater samples exceeded the CTR criteria (Bay et al. 2004). The total number of exceedances out of the total number of samples (70/191) exceeds the allowable frequency listed in Table 4.1 of the Listing Policy.

6.This process is scientifically defensible and reproducible.
 
State Board Decision Recommendation: After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Regional Board Conclusion: This pollutant is being considered for removal from the CWA section 303(d) List under sections 4.1 and 4.6 of the Listing Policy. Under these sections a single line of evidence is necessary to assess listing status.

Four lines of evidence are available in the administrative record to assess pollutant.
A sufficient number of the sediment and water samples exhibited toxicity.

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 CWA 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. Thirty-two of 87 samples exhibited sediment toxicity, and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. Twenty-four of 78 samples exhibited water toxicity, and this exceeds the 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.

LOEs 636 and 637 need to be reviewed and updated. Porewater exceedances need to be removed from sample count.
 
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: LOEs 636 and 637 need to be reviewed and updated. Porewater exceedances need to be removed from sample count.
 
State Board Decision Recommendation: After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Evaluation Guideline: Toxicity is defined as a statistically significant effect in the sample exposure compared to the control using EPA-recommended hypothesis testing. The t-test is used to determine if there is a statistically significant decrease in organism response in the sample as compared to the control. Exceedances are counted with the significant effect code SL. SL is defined as the result being significant compared to the negative control based on a statistical test, less than stated the alpha level, AND less than the evaluation threshold.

Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for removal from the CWA section 303(d) List under section 4.2 of the Listing Policy. Under section 4.2 a single line of evidence is necessary to assess listing status.

Seventy One (71) lines of evidence are available in the administrative record to assess this pollutant.

Two hundred and Eighty One (281) of 1242 samples exceed the Enterococcus Geomean Objective.
One hundred and Twenty Two (122) of 706 samples exceed the Enterococcus Single Sample Objective.
One hundred and Nineteen (119) of 1135 samples exceed the Fecal Coliform Geomean Objective.
Eighty Five (85) of 706 samples exceed the Fecal Coliform Single Sample Objective.
Seventy (70) of 1069 samples exceed the Total Coliform Geomean Objective.
Forty (40) of 375 samples exceed the Total Coliform Single Sample Objective.
Twenty One (21) of 295 samples exceed the Shellfish Harvesting Total Coliform Objective.

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 CWA 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 hundred and Eighty One (281) of the 1242 samples exceed the Enterococcus Geomean Objective, 119 of the 1135 samples exceed the Fecal Coliform Geomean Objective, 70 of the 1069 samples exceed the Total Coliform Geomean, and this does not meet the delisting frequency listed in Table 4.2.
4. One hundred and Twenty Two (122) of the 706 samples exceed the Enterococcus Single Sample Objective, 85 of the 706 samples exceed the Fecal Coliform Single Sample Objective, 40 of the 375 samples exceed the Total Coliform Single Sample Objective, and this does not meet the delisting frequency listed in Table 4.2.
5. Twenty One (21) of the 295 samples exceed the Shellfish Total Coliform Objective, and this meets the delisting frequency listed in Table 4.2.
6. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

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: 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: 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.

Last Listing Cycle's Final Listing Decision: Do Not List on 303(d) list (TMDL required list)(2016)
Revision Status Original
Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: No new data were assessed this cycle. The decision has not changed, and is as follows:

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: 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 cycle. The decision has not changed.

Revision Status Original
Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1, 3.5 and 3.6 of the Listing Policy. Under section 3.1 and 3.5 a single line of evidence is necessary to assess listing status. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

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.

Six lines of evidence are available in the administrative record to assess this pollutant. One of the one samples exceed the OEHHA Fish Contaminant Goal of 0.0052 ppm in shellfish tissue. None of the 26 samples exceed the USEPA screening value of 1.2 mg/kg for the protection of human health. 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.

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 CWA section 303(d) List in the Water Quality Limited Segments category because data that show exceedances were not submitted for this integrated report cycle and are not included in this analysis.

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. One of the one samples exceeded the OEHHA Fish Contaminant Goal of 0.0052 ppm in shellfish tissue. None of the 26 samples exceeded the USEPA screening value of 1.2 mg/kg for the protection of human health. 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, additional data and information are available indicating that standards are not met.

5. The following information indicates that the water quality standard is not being attained:
Data not available for the current listing cycle process were evaluated and are available in the Attachment A to Resolution No. R8-2016-0059. Data were assessed using a human health guideline in Arsenic of 0.026 ug/g and showed that 7/7 filets, 1/1 filet +2/2 mussels exceeded this guideline. These data exceed the allowable frequency listed in Table 3.1 of the Listing Policy.
6.This process is scientifically defensible and reproducible.
 
Regional Board Decision Recommendation: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because data that were assessed show that applicable water quality standards are not being exceeded. There are additional data that are not included in this assessment that show standards are being exceeded. These data should be submitted to CEDEN as soon as possible and prioritized for assessment within the next assessment even if off-cycle for Region 8.
 
State Board Review of Regional Board Conclusion and Recommendation: 5. The following information indicates that the water quality standard is not being attained:
Data not available for the current listing cycle process were evaluated and are available in the Attachment A to Resolution No. R8-2016-0059. Data were assessed using a human health guideline in Arsenic of 0.026 ug/g and showed that 7/7 filets, 1/1 filet +2/2 mussels exceeded this guideline. These data exceed the allowable frequency listed in Table 3.1 of the Listing Policy.

DECISION ID
69057
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)(2016)
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 sections 3.1, 3.5 and 3.6 of the Listing Policy. Under section 3.1 and 3.5 a single line of evidence is necessary to assess listing status. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

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 9 tissue samples taken exceed the cadmium 3 ppm wet weight OEHHA screening value (OEHHA, 1999), none of 91 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. There is sediment toxicity but it does not appear to 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.
 
Regional Board Decision Recommendation: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.
 
State Board Review of Regional Board Conclusion and Recommendation:
 
State Board Decision Recommendation: 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: No new data were assessed this cycle. 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 CWA section 303(d) List in the Water Quality Limited Segments category because data that show exceedances were not submitted for this integrated report cycle and are not included in this analysis.

Pursuant to section 3.11 of the Listing Policy, additional data and information are available indicating that standards are not met.

The following information indicates that the water quality standard is not being attained:
Data not available for the current listing cycle process were evaluated and are available in the Attachment A to Resolution No. R8-2016-0059. Data were assessed using a human health guideline in Chromium of 1.0 ug/g and showed that 7/7 filets exceeded this guideline. Data were also assessed using a wildlife guideline in chromium of 2.5 ug/g that showed 26/31 fish exceeded this guideline. These data exceed the allowable frequency listed in Table 3.1 of the Listing Policy.

This process is scientifically defensible and reproducible.


The decision has not changed, and is as follows:

This pollutant is being considered for listing under sections 2.1 and 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.

Based on the readily available data and information, the weight of evidence indicates that there is insufficient 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. A tissue screening value is not available that 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. 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: 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 cycle. The decision has not changed.

There are additional data that are not included in this assessment that show standards are being exceeded. These data should be submitted to CEDEN as soon as possible and prioritized for assessment within the next assessment even if off-cycle for Region 8.

Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the CWA 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.

The Newport Bay Watershed Diazinon/Chlorpyrifos TMDL was approved by RWQCB on April 4, 2003 and subsequently approved by USEPA on February 13, 2004. This TMDL was developed to address a general pesticides listing. The general pesticides decision was renamed to chlorpyrifos. Both this decision and the chlorpyrifos decision addressed the Newport Bay Watershed Diazinon/Chlorpyrifos TMDL which addressed the general pesticides listing. Samples indicate that beneficial uses are no longer impaired due to diazinon and chlorpyrifos.

One line of evidence is available in the administrative record to assess this pollutant.
Zero of the 91 samples exceed the criteria continuous concentration in saltwater.

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 CWA 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. Zero of the 91 samples exceed the criteria continuous concentration in saltwater 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: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.

Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the section 303(d) list under sections 3.1, 3,5 and 3.6 of the Listing Policy. Under sections 3.1 and 3.5 a single line of evidence is necessary to assess listing status.Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

Currently, Newport Bay 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.

This conclusion is based on the staff findings that:
1. The sediment guidelines and tissue screening values 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. Zero of the 1 sample exceeded the modified OEHHA fish contaminant goal in shellfish tissue. None of the 2 samples exceeded the dry weight ERM sediment quality guideline, and none of 23 samples exceeded the wet weight OEHHA screening value. These do 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.
5. 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: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.
 
State Board Review of Regional Board Conclusion and Recommendation:
 
State Board Decision Recommendation: After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1 and 3.5 of the Listing Policy. Under sections 3.1 and 3.5 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 1 sample exceed the modified OEHHA fish contaminant goal in shellfish tissue.

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 CWA 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 1 sample exceeds the modified OEHHA fish contaminant goal in shellfish tissue and and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1.
4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

Evaluation Guideline: The modified OEHHA Fish Contaminant Goal for hexachlorobenzene in shellfish tissue is 4.3 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 21 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. (Brodberg, R.K., and G.A. Pollock, 1999; Klasing, S., and R. Brodberg, 2008; OEHHA, 2005)

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)(2016)
Revision Status Original
Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1 and 3.6 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status.Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

Three lines of evidence are available in the administrative record to assess this pollutant. None of the 91 water samples exceed the CTR and none of the 6 sediment samples exceed the PEL guideline for this pollutant.

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.

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.

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 91 water samples exceeded the CTR and none of the 6 sediment samples exceeded the PEL for this pollutant. Although sediment toxicity has been documented in this water body, it cannot be associated with this pollutant. 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: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.
 
State Board Review of Regional Board Conclusion and Recommendation:

Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1 and 3.5 of the Listing Policy. Under sections 3.1 and 3.5 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. Zero of the 1 sample exceed OEHHA's screening level guideline in shellfish tissue.

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 CWA 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. Zero of the 1 sample exceed OEHHA's screening level guideline in shellfish tissue and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1.
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 not be placed on the section 303(d) list.

Revision Status Original
Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1 and 3.5 of the Listing Policy. Under sections 3.1 and 3.5 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 sample(s) could be assessed since the reporting limit was above the evaluation 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 CWA 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 data quantity requirements of section 6.1.5 of the Policy.
3. None of the sample(s) could be assessed since the reporting limit was above the evaluation guideline and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1.
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 not be placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating.

Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the CWA 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.

Two lines of evidence are available in the administrative record to assess this pollutant. Zero of the 91 samples exceed the CTR saltwater chronic water quality objective. 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.

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 CWA 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. Zero of the 91 samples exceed the CTR saltwater chronic water quality objective 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 since there is no applicable guideline available for evaluating this pollutant in sediment.
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 not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.

Region 8     
Newport Bay, Upper (Ecological Reserve)
 
Pollutant: Selenium
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)(2016)
Revision Status Original
Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1 and 3.5 of the Listing Policy. Under sections 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 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.

Four lines of evidence are available in the administrative record to assess this pollutant.
None of the 92 samples exceed the selenium CTR saltwater CCC criteria. None of the 23 samples exceed the selenium wet weight OEHHA screening value (OEHHA, 1999). None of the 1 sample exceeds the modified OEHHA fish contaminant goal in shellfish tissue.

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 CWA 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 92 samples exceed the selenium CTR saltwater CCC criteria. None of the 23 samples exceed the selenium wet weight OEHHA screening value (OEHHA, 1999). These 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: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.
 
State Board Review of Regional Board Conclusion and Recommendation:
 
State Board Decision Recommendation: 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: This pollutant is being considered for placement on the section 303(d) list under section 3.1 and 3.6 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

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.

Three lines of evidence are available in the administrative record to assess this pollutant.

None of the 91 samples exceed the CTR saltwater chronic criteria and none of the 2 samples exceed the PEL sediment quality guideline.Although sediment toxicity has been documented in this water body, it cannot be associated with this pollutant.

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 CWA 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 91 samples exceeded the CTR saltwater chronic criteria and none of the 2 samples 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 Decision Recommendation: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because applicable water quality standards are not being exceeded.

Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under section three (3) of the Listing Policy. Under section 3.2, a single line of evidence is necessary to assess the listing status.

One (1) line of evidence is available in the administrative record to assess this pollutant. Zero (0) of the one (1) sample exceeds the 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 CWA 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. Zero (0) of the one (1) sample exceeds the Objective and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 26 samples are needed to determine if a beneficial use is fully supported using table 3.2.
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 not be placed on the section 303(d) list.

Regional Board Conclusion: This pollutant is being considered for removal on the CWA section 303(d) List under sections 2.2 and Sections 4.1,and 4.6 of the Listing Policy. Under Sections 4.1 and 4.6 of the Policy, a minimum of one line of evidence is needed 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.

Six lines of evidence are available in the administrative record to assess this pollutant. 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 against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 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 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 11 samples exceeded the sediment quality guideline and a large number of sediment samples exhibit sediment toxicity in this waterbody. This exceeds the allowable frequency listed in Table 4.1 of the Listing Policy.
4. The Newport Bay Watershed Organochlorine Compounds TMDL was approved by USEPA on 11/12/2013.
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: 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.

Regional Board Conclusion: This pollutant is being considered for placement on the CWA section 303(d) List under sections 3.1, 3.5, and 3.6 of the Listing Policy. Under sections 3.1 and 3.5 a single line of evidence is necessary to assess listing status.Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

Seven lines of evidence are available in the administrative record to assess this pollutant.

One of one samples exceed the 23 ppb modified OEHHHA fish contaminant goal for total DDT in shellfish. Eleven of 30 samples exceed the 100 µg/kg (ppb) wet weight OEHHA screening value. Several samples exhibited sediment toxicity. For benthic degradation; 4 of 16 samples exhibited significant biological community degradation. Three sediment samples were collected, however the number of exceedances cannot be determined due to the unavailability of an applicable sediment quality guideline for total DDT.

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 CWA 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. One of one samples exceeded the 23 ppb modified OEHHHA fish contaminant goal for total DDT in shellfish. 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 sediment samples were collected, however the number of exceedances cannot be determined due to the unavailability of an applicable sediment quality guideline for total DDT. The tissue sample exceedances 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: 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.

Regional Board Conclusion: No new data were assessed this cycle. The decision has not changed, and is as follows:

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 Nutrient TMDL was completed in 1999.

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.
 
Regional Board 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 cycle. The decision has not changed.

Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the section 303(d) list under sections 3.1, 3.5 and 3.6 of the Listing Policy. Under sections 3.1 and 3.5 a single line of evidence is necessary to assess listing status. Under section 3.6 at least two lines of evidence are necessary to assess listing status for pollutants in sediment, and pollutant concentrations in sediment must be associated with sediment toxicity to justify adding that pollutant to the CWA section 303(d) List.

There are six lines of evidence available in the administrative record to assess this pollutant.
Four of 30 samples exceed the OEHHA screening value, one of 1 sample exceeds the modified OEHHA fish contaminant goal in shellfish tissue. Although sediment toxicity has been documented in this water body, none of 4 samples exceeded the dry weight sediment quality guideline.

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. One of 1 sample exceeds the modified OEHHA fish contaminant goal in shellfish tissue. 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: 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 decision be approved by the State Board.
