3.0 STATUS OF PROJECT OPERATIONS (2015—2016) <br /> 3.1 Current Status/Activities <br /> The Solvay Chemicals Yankee Gulch project is presently in interim status with no solution <br /> mining or processing taking place. Ongoing demolition and reclamation activities during the <br /> report period were focused on the well field, upper pump station pad, and test mine/lower <br /> pump station pad. These activities included demolition of pipe and support structures, <br /> inspection and maintenance of storm water control features, security, and maintenance of <br /> access roads, vegetation establishment, reclamation, re-vegetation seeding and control of <br /> noxious weeds. Ground water sampling was conducted quarterly until all of the production <br /> wells were plugged and abandoned. The final groundwater report was submitted on October <br /> 29, 2015. The data presented in the final document summarized the ground water data from <br /> all 60 quarters of operational and baseline monitoring through September 2015. No solution <br /> mining occurred in the well field after 2004. <br /> SIN <br /> t f <br /> M � <br /> { f I Y <br /> A <br /> tr •, *— F <br /> n^a * .. — ...�'•_.""' _w.a.
