As solution mining <br />wells are retired, piping will be moved to a new well. The system will have valves <br />installed along the header at each connection to a lateral line and along atl lateral lines <br />at each connection to an individual well line. These valves will be necessary to allow <br />movement of piping to new wells, but also provide containment for potential pipe <br />failures. <br />The fluids within the well field piping are called injection fluid and production Fluid. <br />Injection fluid is the leaching medium that is injected into each well in order to dissolve <br />the mineral nahcolite (naturally occurring sodium bicarbonate). Production fluid is the <br />fluid that contains the dissolved nahcolite and is purged from each well. Both fluids are <br />sodium solutions but injection fluid is a lean sodium solution and production fluid is a <br />concentrated sodium solution. The fluid that would be recirculated would consist of <br />either injection fluid, production Fluid, or a combination of the two. The following <br />tables summarize the operating characteristics of injection fluid and production fluid <br />piping. These characteristics are approximate and will vary over time and with <br />conditions. <br />Preliminary Response Plan <br />Yankee Gulch Sodium Minerals Project <br />A mer¢an Soda, L.
