Expected TMDL Completion Date:	2222
Impairment from Pollutant or Pollution:	Pollution

Weight of Evidence:	This pollutant is being considered for removal from the section 303(d) list under section 4.9 of the Listing Policy. Under this section 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. None of samples exceeded the water quality criteria for benthic invertebrates. 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. 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 nineteen samples exceeded the water quality criteria for benthic invertebrates and this exceeds the allowable frequency listed in Table 4.2 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.

RWQCB Board Decision / Staff 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.

Impairment from Pollutant or Pollution:	Pollutant

Weight of Evidence:	This pollutant is being considered for removal from the section 303(d) list under section 4.6 of the Listing Policy. Seven lines of evidence are available in the administrative record to assess pollutant. Ten of 35 samples exceed the water quality objective for water 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 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. Ten of 35 samples exceeded the toxicity objective and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy.

RWQCB Board Decision / Staff 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.
