The three basins include Water Resource Inventory Areas (WRIAs) 37, 38 and 39; the Lower Yakima, Naches and Upper Yakima Basins respectively. To date, the Phase II Level 1 technical compilation is complete, and Phase II Level 2 data analysis and compilation as well as Phase III preparation of a watershed plan have been started. The Planning Unit has submitted applications to Ecology for supplemental funds to support.studies for instream flows and storage in each of the three WRIAs. The approach that the Planning Unit has decided to adopt in conducting work under supplemental funds is to focus on specific projects that can be reasonably advanced within the amount of funds available, have the potential for broad application or benefits, and have the possibility of being implemented within a reasonable time horizon. This scope of work is for the evaluation of storage options in the Naches Basin, WRIA 38. Aquifer Storage & Recovery (ASR) has been identified as a water resource management strategy for consideration in WRIA 38 to increase basin storage capacity (EES, 2001). Implementation of an ASR program is expected to accrue benefits to reaches of the Naches River as well as the Yakima River downstream from the confluence with the Naches River and into the Lower Yakima Valley. Many of the findings of such a study are expected to be applicable to all WRIAs in the Yakima Basin. Artificial Recharge is any activity that purposely introduces water to groundwater systems. ASR is a specific application of artificial recharge in which water is recharged to an aquifer and stored for later recovery and use. Typically, ASR involves diverting water during times of higher availability, usually surface water during the winter and spring runoff season, and recharging it into aquifers that act as storage reservoirs. The stored water is then withdrawn during times of higher demand and lower availability. Conventional ASR projects operate on an annual cycle that withdraw during dry summer seasons, although longer multi -year cycles may also be considered such as recharging every year, and only withdrawing during drought years. ASR is a conjunctive use tool in which the use of surface water and groundwater can be coordinated to minimize impacts to the hydrologic system, and even provide environmental benefits. Water recharged during winter is cold, and recovery is generally less than 100% of that recharged. The unrecovered water remaining in the aquifer system then discharges to surface water thereby supporting baseflows that are necessary to the maintenance of salmonid habitat. ASR also provides the option of discontinuing surface water diversions during :critical flow periods while providing continued reliability of water supply through the recovery of water previously recharged to an aquifer. • Golder Associates • February 19, 2002 2 983- 1085- 001.9000 Other applications of artificial recharge may be considered to: enhance base flows for habitat improvement; restore aquifer water levels that have been lowered over decades as a result of over - extraction; as mitigation for the issuance of new water rights; and other purposes. Given the potential environmental benefits associated with artificial recharge or ASR, these technologies may be used to allow issuance of new water rights as an integral part of exercising a new right or as a separate mitigation. Although ASR is relatively new to Washington State, it is a well- established technology that is used elsewhere in the United States (California, Arizona, Florida, Texas, etc.) and the world (England, Netherlands, Israel, and Australia). Artificial recharge may occur by surface spreading /flooding water over land for infiltration (infiltration basins), or directly through wells to deep aquifers. The cost per acre -foot of water using infiltration basins is low and may be considered for agricultural purposes. ASR through wells is relatively more expensive due to the construction cost of wells and the need to pre -treat the water to avoid clogging of the wells, and is generally only considered for high value per gallon uses such as municipal and some industrial /commercial applications. The most significant barrier to the implementation of ASR in Washington State is the lack of a reliable regulatory environment within which to plan and invest in associated infrastructure. BACKGROUND Water right permitting of an ASR program is possible under the water code before the legislature passed House Bill 1832 in the 2000 session. However, one of the steps to permitting an ASR project under the pre - existing code involves establishment of a Groundwater Management Area, which is a cumbersome approach. To provide a smoother process, a bill specific to permitting ASR projects was passed in 2000 (HB 1832). Rule- making for this legislation related to ASR has been on -going since the middle of 2000 and has been delayed due to reallocation of Ecology staff to drought response during the summer of 2001. In developing an ASR rule, two significant regulatory issues are recognized: 1) how much water may be recovered after recharge (a water right issue); and, 2) resolving the recharge of drinking water that has been disinfected by chlorinated to comply with federal law, with state law prohibiting the introduction of chlorinated byproducts to groundwater without a variance (a water quality issue). The water right issue is expected to be based on technical analysis that will be specific to each project. Variances to meeting default water quality regulations may be granted for five -year periods. However, uncertainty of renewal of a variance causes funding of associated infrastructure difficult. The water quality issue may require a statutory fix requiring legislation. The City of Yakima has been evaluating the feasibility of ASR using surface water from the Naches River for the past three years, and has jointly with the Bureau of Reclamation invested on the order of S350,000. This work has advanced the understanding of the feasibility of ASR from the conceptual stage to determining that it is technically feasible (Golder, 2000a, 2000b and 2001). The next step toward implementation of a full ASR program using the Naches River as a source of water for an ASR program is to provide a technical analysis needed to support establishing a reservoir permit and estimating how much water may be recovered under a secondary permit. As this has not been yet been accomplished in the state to date, developing a technical analysis that is accepted by Ecology will assist in establishing the foundation for defining criteria for such analysis. and significantly advance the ability to implement ASR in the Yakima Basin. The • Golder Associates February 19, 2002 3 983 -1085- 001.9000 Cities of Kennewick and Richland have conducted a feasibility study of ASR, the City of Ellensburg recognizes ASR as a resource management tool that may be considered in the future, and the Town of Roslyn is considering evaluating the feasibility of ASR. • GOAL The goal of this work is to identify and advance means of using the natural storage capacity available in the aquifer systems of the Yakima Valley, and in particular, using surface water from the Naches River. The resulting effects of increasing the use of natural aquifer storage capacity will be to: allow alternatives to the diversion of surface water during critical periods; increase redundancy and reliability of municipal water systems; partially restore depleted aquifer levels; and, improve the quantity and quality of stream base flows which will benefit salmonid species. • APPROACH The approach in this scope of work is to provide supporting documentation in the form of technical analysis and /or strategic planning for implementation of aquifer storage projects that will result in better water resource management in the Naches Basin, and to extend such support to the rest of the Yakima Basin. Input and review will be solicited from key entities on various tasks (e.g., Ecology on proposed permit structures, irrigators on the use of irrigation canals, municipalities on infrastructure costs, etc.). • • • Golder Associates February 19', 2002 4 983- 1085- 001.9000 SCOPE OF WORK The following tasks comprise this scope of work: Task Allocated Budget 100 Project management and scoping. $5,000 200 Conduct a technical analysis for use in establishing a permitting $40,000 structure for the implementation of ASR in the Naches/Middle Yakima Basin. 300 Conceptual assessment of application of ASR to other locations $5,000 in the basin (e.g., Cities of Ellensburg, Kennewick, Richland, Roslyn and others). 500 Reporting and presentations $20,000 600 Independent review. $5,000 Total: $75,000 Work will start immediately upon authorization to proceed. All work will be based on existing, readily available information. No field work is included in this scope of work. The schedule for completion is June 30, 2002. Task 100: Meetings, Presentations and Project Management Purpose: Cost control and cost accounting will be conducted to ensure that the project is completed within budget. Meetings with the City throughout the project. Deliverable: Letter progress reports will accompany all monthly invoices. The progress report will describe work conducted in the last month, important tasks scheduled for the coming month, and any changes in the scope of work, schedule or budget. The invoice will summarize by task and overall project. charges to date, charges in the current month, total budget, and budget remaining. Two Planning Unit meetings will be held: one to discuss the proposed scope of work before work is started: and, one upon completion of all work to present the findings. Budget: The estimated cost to conduct the above - described work is $5,000. This cost estimate includes administrative work, and meetings including preparation and graphics support for each meeting. Task 200: Model Storage of Naches River Water Using ASR Golder Associates February 19, 2002 5 983 -1085- 001.9000 Purpose: To conduct a technical analysis for use in establishing a permitting structure for the implementation of ASR in the Naches/Middle Yakima Basin. Description: A simplified three - dimensional computer model of the Ahtanum -Moxee Basin will be developed using software developed by the United States Geological Survey (ModFlow) to simulate the effects of artificially recharging water and the resulting decay of the increased storage over time. The model will be structured as a four layer model consisting of surficial alluvial sediments and three members of the Upper Ellensburg Formation. The contact between the Upper Ellensburg Formation and underlying basalt will be assumed to be a no -flow boundary. The model will simulate a minimum period of three years in order to assess inter - annual carry over of storage. The relative effects of recharge and the dissipation of the resulting pressure and storage will be simulated. At this time (initial modeling study), it is not recommended that the model accurately simulate all hydrogeologic phenomenon such as the effects of seasonal pumping of the aquifer system for irrigation use. A simulation of relative effects as opposed to absolute effects is assumed to be sufficient to demonstrate the ASR permitting purposes. Deliverable: Documentation of the model will be compiled to allow a thorough independent review. A report will outline then conceptual model and the details of the setup of the numerical model. Assumptions. estimates and data sources used to prepare model input will be identified. Results of the model simulations will be described and tabulated, and figures will be prepared in the form of graphs, maps. and other formats to clearly communicate the findings. Budget: The budget allocated for this task is 540,000. Task 300: Identify Other Candidates for ASR and Artificial Recharge Purpose: To identify other candidates for conventional ASR, constraints for implementation, and potential benefits including improved reliability of supply and environmental benefits. 300: Description: In general, conventional ASR (i.e., recharge of treated water through wells), requires an appropriate hydrogeological setting, a source of treated water for recharge, and a market demand. Candidates for conventional ASR will be identified and characterized on the basis of: existing infrastructure (e.g., water treatment plants); areas of depleted aquifer levels; the presence of suitable geological structures (characterized at a reconnaissance scale); demand for new water rights; potential permitting problems or opportunities; and. other criteria. Information will be collected and compiled through solicitation to stakeholders. Depth of analysis will be restricted to the conceptual level. Deliverable: Findings will be incorporated into a final report. Included will be matrix tables listing variables for each candidate project and will separately rank projects for instream environmental benefits and for out-of-stream water supply benefits. Budget: A budget of S5,000 is allocated to Task 400. Task 400: Reporting Golder Associates February 19, 2002 6 983 -1085- 001.9000 Purpose: To compile the findings of all tasks in this scope of work into a comprehensive document. Description: Each task will comprise one chapter. An executive summary will be prepared containing the key findings, identified options for action and recommendations. Golder will compile and summarize the comments received on the draft report. If necessary (e.g., there are conflicting edits, or the suggested changes cannot be accommodated within the available budget), Golder will take direction from the Planning Unit representative administering the contract with Golder on how to proceed. Assumptions: Ecology will compile all comments on the draft report and resolve conflicting suggested edits. Deliverable: Five hardcopies of the a draft including tables and color figures will be submitted for review. A presentation on the findings will be made. An electronic copy of the report (e.g., pdf format) will be provided on a compact disc for posting on a web site. Five hardcopies and one electronic copy on a compact disk of the final report will be delivered to the Planning Unit's representative administering the contract with Golder. Budget: A budget of S20,000 is allocated to this task. Task 500: Independent Review Purpose: To ensure quality control and improve the quality of the scope of work and the final report. Description: Mr. Frank Spane of Batelle will be retained to provide review and comments on the original scope of work and a preliminary draft of the final report (i.e., Mr. Spanne will review a version of the draft before it is issued to the Planning Unit for review). Deliverable: A letter from Mr. Spane will be included in the final report attesting that he is satisfied with the report or identifying specific qualifiers. Budget: A budget of S5,000 is allocated to this task. Golder Associates BUSINESS OF THE CITY COUNCIL YAKIMA, WASHINGTON AGENDA STATEMENT Item No. * 1 O For Meeting of April 2, 2002 ITEM TITLE: Consideration of a Resolution Ratifying the Assistant City Manager's signature on the `Added Task Order #4 for ASR Project on City Contract #98 -34 with Golder Associates.' SUBMITTED BY: Dueane Calvin, Water /Irrigation Manager CONTACT PERSON/TELEPHONE: Dueane Calvin 576 -6154 SUMMARY EXPLANATION: Over the last several weeks the Yakima Basin Watershed Planning Unit has been working with DOE in an effort to develop a scope of work to undertake an expanded storage assessment in WIRA's 37, 38 and 39. This effort would involve a diversity of effort, such as an expanded assessment of ASR Project currently being worked on by the City of Yakima. When these projects were selected it was done so that they would yield the maximum amount of product for the dollar being spent. Consequently, the City project was selected to be included in this short term program (work must be completed and submitted to the Planning Unit by June 30, 2002). Staff felt that it would be beneficial to the City of Yakima's long -range plans to obtain this enhancement of our program at no cost. Subsequently, Golder Associates developed a scope of work that has now been accepted by both the Planning Unit and the DOE. The Department of Ecology will furnish the City with up to $75,000 of grant monies, which would then be paid directly to Golder for the enhancement work done on the ASR program. The time constraints in which the work must be accomplished required us to sign the new Task Order as soon as possible. The completed report will become a part of our program as well as being incorporated into the implementation plan for the Watershed.
