Common use of Methodologies Clause in Contracts

Methodologies. The survival standards set forth in Section 5 “Passage Survival Plan” shall be measured using the best available technology and study designs approved by the Coordinating Committee. Current methodologies are summarized in Supporting Document 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. 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). A study result meeting this precision level will automatically be included in the three-year average, unless the study is determined to be invalid by the Coordinating Committee for other reasons. If, however, a study is considered to have met all other testing protocols, and the Coordinating Committee agrees, it may be included in the calculation of the three-year average so long as the standard error around the point estimate does not exceed plus or minus 3.5%. This decision is not subject to Dispute Resolution. Point estimates of survival measurements from the three years of studies shall be averaged (arithmetic mean). The point estimate of the average will be used to compare against the pertinent survival standard. If the averaged point estimates equals or exceeds the survival standard, then the standard has 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.

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 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). A Results from a study result meeting this precision level will automatically be included in the three-year average, unless the study is has violated critical model assumptions or has been determined to be invalid by the Coordinating Committee for other reasonsCommittee. If, however, If a study is considered to have met meet all other testing protocols, and the Coordinating Committee agrees, it may be included in the calculation of the three-year average so long as testing protocol and model assumptions and provided that the standard error around the point estimate does not exceed plus or minus 3.5%. This decision is not subject to Dispute Resolution, then the Coordinating Committee, following unanimous approval, may utilize this information in the calculation of the three-year average. Point estimates of survival measurements measured from the three years of valid studies shall be averaged (arithmetic mean). The point estimate of the average will be used arithmetic) to compare against the pertinent Plan Species Survival Standard. The use of survival standard. If the averaged point estimates equals or exceeds the survival standard, then the studies with standard has been achievederrors 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.
