Director January 30, 2019 Randy Gene Larsen Cove Waterworks Water System 1290 East 12600 North Cove, UT 84320 Subject: Plan Approval, Adkins Spring (WS001) Rehabilitation Project; Cove Waterworks Water System, System #03006, File #11071 Dear Mr. Larsen: On March 15, 2018, the Division determined that Atkins Spring (identified as WS001 in the Division’s database) is under the direct influence of surface water (UDI). The Division records indicated that Cove Waterworks Water System had a history of total coliform positive (TC+) samples. The Division staff conducted onsite inspections of this spring on March 21, 2017 and January 4, 2018, and observed several significant physical deficiencies of this spring. Pursuant to this determination, the water system was required to take a number of actions within certain time frames to eliminate significant risks to public health. Within 18 months of the date of the notification letter, the water system was required to implement one of the following permanent solutions: 1. Abandon Atkins Spring (WS001) as a drinking water source permanently by physically disconnecting it from your water system. 2. Have installed and be operating an approved surface water treatment facility that successfully treats this source and meets the surface water treatment requirements. 3. Complete remediation of the source to eliminate the surface water influence. In some cases, geological conditions might make it impossible to exclude surface water influence and the expense of the remediation could be futile. We recommend that you consult with a hydrogeologist first before pursuing this option. The Division of Drinking Water (the Division) received design drawings and specifications for the Adkins Spring Rehabilitation Project from your consultant, Chad Brown, P.E., Franson Civil Randy Gene Larsen Page 2 of 3 January 30, 2019 Engineers on December 10, 2018. Plan review comments were returned on January 2, 2019, revised drawings were then submitted January 10, 2019 and redline comments were returned on January 14, 2019. Final revision drawings and specifications were submitted to the Division on January 23, 2019. Our understanding of the project is the redevelopment of an existing spring collection system consisting of clearing the existing spring collection area of overgrown trees and vegetation. The project includes the installation of a new collection system of perforated and non-perforated PVC pipe, gravel bedding, geomembrane liner, clay cutoff wall, collection manholes as shown in the design drawings. A new transmission line will be installed from the spring collection area to the existing concrete storage tank downstream of the spring collection zone. The project also includes the installation of a new stock tight fence around the Atkins Springs Rehabilitation project area. We have received the following information for Adkins Spring Rehabilitation Project: 1. Project Notification Form 2. Plans and specifications for spring redevelopment developed per R309-515-7, Ground Water - Springs We have completed our review of the plans and specifications, stamped and signed by Chad H. Brown, P.E., and dated November 18, 2018, and find they basically comply with the applicable portions of Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans for redeveloping Adkins Spring and the Rehabilitation project are hereby approved. This approval pertains to construction only. Following completion of construction, you must obtain an Operating Permit prior to placing the Adkins Spring and Rehabilitation Project into service. A checklist outlining the spring approval process, including the items required for issuing an Operating Permit is enclosed for your information. Enclosed please also find an Operating Permit Checklist for other components of this project. Before requesting an Operating Permit for this project, you must submit the required new source chemical analysis data to the Division for review to determine whether additional treatment is required for using the Adkins Spring as public drinking water source. Please note that: • The Division protocol requires two consecutive low-risk MPA samples following redevelopment for this source to be considered not UDI. Approvals or permits from the local authority or county may be necessary before beginning construction of this project. As the project proceeds, notice of any changes in the approved design, as well as any change affecting the quantity or quality of the delivered water, must be submitted to the Division. We may also conduct interim and final inspections of this project. Please notify us when actual construction begins so that these inspections can be scheduled. Randy Gene Larsen Page 3 of 3 January 30, 2019 This approval must be renewed if construction has not begun or if substantial equipment has not been ordered within one year of the date of this letter. If you have any questions regarding this approval, please contact Michael Newberry, P.E., of this office, at (801) 536-4293, or Nathan Lunstad, Engineering Manager, at (385) 239-5974.
