<br />N <br />~ <br />W <br />C.Jl <br /> <br />Water and Power Resources Service <br />tWPRS) Salinity Control Programs <br /> <br />Construction of the salinity projects authorized by <br />Title II of P.L. 93-320 or their equivalents is necessary <br />to maintain salinity in the lower mainstem of the Colorado <br />River at or below the 1972 levels while the Basin states <br /> <br />continue to develop their compact-apportioned waters. <br /> <br />Paradox Valley Unit - The well field pump tests are <br /> <br /> <br />continuing in order to determine the amount of pumping <br /> <br />required to control the salt discharge into the Dolores <br />River. Salt pickup in 1980 during the major pump testing <br />period is significantly reduced from past years. It is <br />now anticipated that further investigation will confirm <br />that a lower pumping rate of 0.5 to 1. 5 ft3/s could be used. <br />At the request of the Environmental Protection Agency <br />(EPA), WPRS is investigating the feasibility of brine <br /> <br />disposal by deep well injection. <br /> <br />A deep well injec- <br /> <br />tion study by professional services contract has been <br /> <br />solicited. Should results of that study be favorable, a <br />verification test program will be evaluated and a pilot <br />well and related facilities would probably be constructed <br />beginning in late 1981. A meeting was held with represen- <br />tatives of EPA in August to discuss the impacts of new <br />regulations dealing with both the Underground Injection <br />Control (UIC) and Hazardous Wastes Programs. WPRS has the <br /> <br />responsibility for determining if brine is a hazardous waste. <br /> <br />-7- <br /> <br />,;" ,;j <br /> <br />I <br />J..,.". <br />
