Methodologies. The survival standards contained within Section 4 (Passage Survival Plan) will be measured using the best available technology and study designs approved by the Coordinating Committee. Current methodologies are summarized in Supporting Document C. These methodologies are not exclusive, and may be updated based on new information or techniques. Juvenile Plan Species survival shall be measured at a ninety-five percent (95%) confidence level, with a standard error of the estimate that shall be not more than plus or minus 2.5% (i.e. 5% error). Results from a study meeting this precision level will automatically be included in the three-year average, unless the study has violated critical model assumptions or has been determined to be invalid by the Coordinating Committee. If a study meet all of the testing protocol and model assumptions and provided that the standard error around the point estimate does not exceed plus or minus 3.5%, then the Coordinating Committee, following unanimous approval, may utilize this information in the calculation of the three-year average. Point estimates of survival measured from the three years of valid studies shall be averaged (arithmetic) to compare against the pertinent Plan Species Survival Standard. The use of survival studies with standard errors between 2.5% and 3.5% shall not be subject to Dispute Resolution. If the average of the 3 years of survival measurements is no more than 0.5 percent below the survival standard, the Coordinating Committee may decide whether an additional year of study is appropriate. If an additional year of study is undertaken, the study result (if valid) will be included in the calculation of the arithmetic mean. The testing shall reflect Representative Environmental Conditions and Representative Operational Conditions for each test, for each Plan Species and life history. Studies conducted during years where flow conditions, during the study, fall between the 10% and 90% points on the Flow Duration Curve (See Section 14, Figure 2a and 2b) shall be considered to have satisfied Representative Environmental Conditions (See Section 13, “Representative Environmental Conditions”). Should flow conditions fall outside the 10% and 90% points on the Flow Duration Curve but be between the 5% and 95% points on the Flow Duration Curve, then the Coordinating Committee, following unanimous approval, may utilize this information in the calculation of the three-year average. The use of survival studies that fall outside the 10% and 90% points on the Flow Duration Curves shall not be subject to Dispute Resolution. The Flow Duration Curves shall be subject to periodic review based upon new information. The testing shall consider direct, indirect and delayed mortality wherever it may occur and can be measured (as it relates to the Project) given the available mark-recapture technology. The Coordinating Committee shall facilitate the availability of test fish for studies that may include rearing of additional fish beyond that required to meet NNI.

Methodologies. The survival standards contained within set forth in Section 4 (5 “Passage Survival Plan) will ” shall be measured using the best available technology and study designs approved by the Coordinating Committee. Current methodologies are summarized in Supporting Document C. D “Briefing Paper Estimating Survival of Anadromous Fish through the Mid-Columbia PUD Hydropower Projects”. These methodologies are not exclusive, and may be updated based on new information or techniques. Juvenile Plan Species survival A valid study is one in which the study design, implementation, and criteria are determined to have been met by the Coordinating Committee, and one in which the study took place during Representative Flow Conditions and normal project operating conditions consistent with the approved study design. The Coordinating Committee will evaluate each study after it is completed to see if previously agreed-to criteria are met. All studies will be evaluated for quality control. If the Committee agrees that critical criteria were violated, then the study will not be included in the overall average over the three years of testing, and an additional year of testing will take place. In the event that the additional year’s test is invalid, the Coordinating Committee will decide how to address the requirement for three years of testing. Survival studies shall be measured at a ninety-five percent (95%) confidence level, with a standard error of the estimate that shall be not more than plus or minus 2.5% (i.e. 5% error). Results from a A study result meeting this precision level will automatically be included in the three-year average, unless the study has violated critical model assumptions or has been is determined to be invalid by the Coordinating CommitteeCommittee for other reasons. If If, however, a study meet is considered to have met all other testing protocols, and the Coordinating Committee agrees, it may be included in the calculation of the testing protocol and model assumptions and provided that three-year average so long as the standard error around the point estimate does not exceed plus or minus 3.5%, then the Coordinating Committee, following unanimous approval, may utilize this information in the calculation of the three-year average. This decision is not subject to Dispute Resolution. Point estimates of survival measured measurements from the three years of valid studies shall be averaged (arithmetic) arithmetic mean). The point estimate of the average will be used to compare against the pertinent Plan Species Survival Standardsurvival standard. The use of If the averaged point estimates equals or exceeds the survival studies with standard, then the standard errors between 2.5% and 3.5% shall not be subject to Dispute Resolutionhas been achieved. If the average of the 3 years of survival measurements is no more than 0.5 percent below the survival standard, the Coordinating Committee may decide whether an additional year of study is appropriate. If an additional year of study is undertaken, the study result (if valid) will be included in the calculation of the arithmetic mean. 5.3 Phased Implementation of Measures to Achieve the Survival Standards. The testing survival standards contained in this Section 5 “Passage Survival Plan” will be achieved in three phases. Under Phase I, the District shall reflect Representative Environmental Conditions and Representative Operational Conditions for each test, for each implement the "Phase I Plan Species and life historyto Achieve the Survival Standards" set forth in Section 5.3.1. Studies will be conducted during to determine the survival rates beginning in 2004 and lasting for three years, unless additional years where flow conditions, during the study, fall between the 10% and 90% points on the Flow Duration Curve (See Section 14, Figure 2a and 2b) shall be considered of studies are agreed to have satisfied Representative Environmental Conditions (See Section 13, “Representative Environmental Conditions”). Should flow conditions fall outside the 10% and 90% points on the Flow Duration Curve but be between the 5% and 95% points on the Flow Duration Curve, then by the Coordinating Committee, following unanimous approval, may utilize this information in . Following the calculation completion of the three-year averagestudies, the Coordinating Committee will determine whether the pertinent survival standards have been achieved. The use Depending on the results of this determination, the District will either proceed to Phase II (if the applicable survival standard has not been achieved) or Phase III (if the applicable survival standard has been achieved). Phase III also includes steps designed to address gaps in the available information. Juvenile survival studies that fall outside conducted during Phase I may result in different phase designations for each of the 10% and 90% points plan species. For example, the District may move to: Phase II (Additional Tools); Phase III (Standard Achieved); Phase III (Provisional Review); or to Phase III (Additional Juvenile Studies) as described in Figure 1, depending on the Flow Duration Curves shall survival results for individual plan species. If the Coordinating Committee cannot be subject agree on Phase designation, the Coordinating Committee may agree to require an additional year of study to resolve the disagreement, or a Party may institute Section 11 “Dispute Resolution. The Flow Duration Curves shall be subject ” to periodic review based upon new information. The testing shall consider direct, indirect determine the Phase designation or address the need for Additional Tools during the period of measurement and delayed mortality wherever it may occur and can be measured (as it relates to the Project) given the available mark-recapture technology. The Coordinating Committee shall facilitate the availability of test fish for studies that may include rearing of additional fish beyond that required to meet NNIevaluation.
