Page 6 of 52 Through the Drought Response Program, Reclamation invites states, tribes, irrigation districts, water districts, and other organizations with water or power delivery authority to leverage their money and resources by cost sharing with Reclamation on Drought Resiliency Projects that will increase the reliability of water supply; improve water management; and provide benefits for fish, wildlife, and the environment to mitigate impacts caused by drought. The City of Santa Ana, in Orange County, California, will rehabilitate existing Well 32 that was decommissioned in 2004 due to high nitrate concentrations and operational inefficiencies. The City will retrofit the well to meet current standards and will also construct approximately 3,250 feet of new pipeline to convey the well's flow to Garthe Reservoir where the water will be blended with other water sources to lower nitrate levels. This project will provide the City with an additional 4,000 acre-feet of water per year for municipal and industrial use. Rehabilitating Well 32 will assist the City in building long-term drought resilience by increasing local water supplies and decreasing reliance on imported water supplies. This project supports goals identified in the City's Drought Action Plan. 4. PERIOD OF PERFORMANCE AND FUNDS AVAILABILITY This Agreement becomes effective on the date shown in Block 13a of Page 1 of this agreement, United States of America, Department of the Interior, Bureau of Reclamation, Assistance Agreement. The Agreement shall remain in effect until the date shown in Block 8 of Page 1 of this agreement, United States of America, Department of the Interior, Bureau of Reclamation, Assistance Agreement. The period of performance for this Agreement may only be modified through written modification of the Agreement by a Reclamation Grants Officer (GO). No legal liability on the part of the Government for any payment may arise until funds are made available, in writing, to the Recipient by the Grants Officer. The total estimated amount of federal funding for this agreement is $750,000.00, of which the initial amount of federal funds available is limited to $740,000.00 as indicated by "this obligation" within Block 10 of Page 1 of this agreement, United States of America, Department of the Interior, Bureau of Reclamation, Assistance Agreement. Subject to the availability of Congressional appropriations, subsequent funds will be made available for payment through written modifications to this agreement by a Reclamation Grants Officer. 5. SCOPE OF WORK AND MILESTONES City of Santa Ana Water Well No. 32 was originally drilled in 1984 and had the capacity to produce up to 4000 acre-feet of groundwater per year. Due to its later high nitrate concentrations and low operational deficiencies, the City discontinued groundwater production from Well 32 in 2004. This project will blend high nitrate water produced by Well 32 with low nitrate levels of groundwater produced by Santa Ana Wells 36 and 39, in the reservoirs located at the John Garthe Pump Station Complex. Major components of this project include: 1. Rehabilitate Well -This includes cleaning the entire well casing, including all well screens with chemical (i.e. acids) and mechanical (i.e. nylon wire brush) methods. The well head will be raised to meet current California Division of Drinking Water Agreement No. R18AP00081 Agreement Template 2 0 D -1 0 (03/2019)
