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 section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. Two lines of evidence are available in the administrative record to assess this pollutant. Zero of sixty-four samples exceed the CTR criterion continuous concentration for dissolved arsenic to protect aquatic life in freshwater for COLD, and 0 of 63 samples exceed the CA Department of Health Services MCL thought to be protective of drinking water for MUN. 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 sixty-four samples exceed the CTR criterion continuous concentration for dissolved arsenic to protect aquatic life in freshwater for COLD, and 0 of 63 samples exceed the CA Department of Health Services MCL thought to be protective of drinking water for MUN 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.

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.

DECISION ID	93912	Region 5
Yuba River (confluence of North and Middle Yuba Rivers to Englebright Lake)

Pollutant:	Zinc
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(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 section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. One line of evidence is available in the administrative record to assess this pollutant. Zero of four samples exceed the California Toxics Rule (CTR) criterion continuous concentration to protect aquatic life in freshwater (hardness corrected) for COLD. 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 four samples exceed the California Toxics Rule (CTR) criterion continuous concentration to protect aquatic life in freshwater (hardness corrected) for COLD 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.

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.

Data Used to Assess Water Quality:

Fish were sampled for tissue analysis at three locations from the Yuba River, Middle Fork. A total of 2 out of 19 samples exceeded the USEPA fish tissue criterion for human health. 1) Yuba River, Middle Fork upstream of Oregon Creek: The average wet weight mercury concentration in fish tissue was 0.38 ppm for the 5 samples collected at this location. The number of fish collected per sample, the measured mercury concentrations in fish tissue, and the number of exceedances are, by species: Rainbow Trout- 3 samples, 0.15-0.21 ppm (average 0.18 ppm), no exceedances; Sacramento Pikeminnow- 2 samples, 0.56 and 0.81 ppm, 2 exceedances. 2) Yuba River, Middle Fork upstream of Kanaka Creek: Nine Rainbow Trout samples were collected for tissue analysis at this location. None of the 9 samples exceeded the USEPA fish tissue criterion for human health. The wet weight mercury concentrations of the 9 samples ranged from 0.10 ppm to 0.24 ppm, with an average of 0.16 ppm. 3) Yuba River, Middle Fork upstream of Plumbago Road: Five Rainbow Trout samples were collected for tissue analysis at this location. None of the 5 samples exceeded the USEPA fish tissue criterion for human health. The wet weight mercury concentrations of the 5 samples ranged from 0.05 ppm to 0.19 ppm, with an average of 0.11 ppm. All 19 samples were collected from fish with total lengths greater than 150 mm, which represent fish most commonly caught and consumed by sport fishers and their families.
