Show The Drinking Water Board, through the Division of Drinking Water, also operates under the federal Safe Drinking Water Act. This act sets federal drinking water standards and regulations. The recently amended bill now includes a revolving loan program to provide money to states to construct drinking water treatment plants. It also relaxes some Environmental Protection Agency requirements for setting standards for drinking water and provides more flexibility for small and rural systems. The Division of Drinking Water serves as staff for the Drinking Water Board to assure compliance with the standards. At the local level, considerable reliance is placed on public water supply operators. Those operating systems serving over 800 people are currently required to have state certification. Water systems serving fewer than 800 people will only need to have a certified operator if the water system has some sort of treatment facility in place. The water systems are listed in Table 11- 1. The Division of Drinking Water also administers the Drinking Water Source Protection Program. This program is designed to protect groundwater quality. Owners of wells and springs are required to develop protection programs based on the areas of influence around the source. The outcome of the program is to develop controls for potential sources of pollution to the groundwater. The Drinking Water Source Protection Program includes monitoring delivered drinking water quality as well as water source protection. 7.6 Environmental Considerations Although county and city planning documents have identified a need to establish minimum stream- flow requirements for the Wasatch Mountain streams, none have been any established. Some canyon streams on the east bench fall within the limits of federally declared wilderness areas. Consequently, the streams within wilderness areas will have federally imposed restrictions barring development, stream alterations and withdrawals. Also, the Corps of Engineers ( COE) has a federally mandated responsibility to review and approve or disapprove any stream channel alterations or modification. This includes wetlands as well as stream systems. The COE is assisted in this review process by the Division of Water Rights, the Division of Water Quality, the Division of Wildlife Resources, and the Division of Forestry, Fire and State Lands. 7.7 Dam Safety All dams in Utah which store in excess of 20 acre- feet of water or whose failure could cause loss of life or property damage are assigned a hazard rating. The hazard rating does not reflect the condition or reliability of the dam, but rather the potential for loss of life in the event of a dam failure. Hazard ratings are either high, moderate or low. The hazard rating is used to determine the frequency of inspections. High- hazard dams are inspected yearly; moderate hazard, every other year; and low hazard, every fifth year. Following the inspection, a letter from the State Engineer suggests maintenance needs and requests specific repairs. The State Engineer is empowered to declare a dam unsafe and order it breached or drained. But every effort is made to work with dam owners to schedule necessary actions. The Division of Water Rights has design standards which are outlined in a publication entitled, Rules and Regulations Governing Dam Safety in Utah. Plans and specifications must be consistent with these standards. Dam safety personnel monitor construction to insure compliance with plans, specifications and design reports. Any problems are resolved before final approval is given. Table 7- 2 gives the hazard rating for each reservoir in the Jordan River Basin. See Table 6- 1 for information on dam owners and stream locations. • Table 7- 2 HAZARD RATING OF JORDAN RIVER BASIN RESERVOIRS Name Built Total Storage ( acre- feet) Hazard Rating Little Dell 1993 20,500 High Mountain Dell 1925 3,514 High Lake Mary- Phoebe 1915 85 High i Jordan Valley Water Treatment Upper Pond 1981 550 Moderate Lower Pond 1982 46 Moderate Twin Lakes 1914 486 High Red Buttea 1930 385 High White Pine Lake 1933 315 High Bell Canyon ( Lower) b 1907 25 High Red Pine Lake 1929 202 High Secret Lake 1926 60 Moderate a) Red Butte is currently inactive with stream flow s passing directly through the outlet works. b) Lower Bell Canyon Dam has been breached, by order of the State Engineer. 7- 6 |
