used for land application which was developed for warehouse space. Three additional <br /> wells which were installed as part of a petroleum fuel leak investigation exist at the <br /> processing facility and may be useful for determining background groundwater <br /> conditions. <br /> Recently, the Discharger installed a reverse osmosis unit to replace their water softening <br /> unit, and reduced the number of cleaning cycles, resulting in better quality wastewater with <br /> a specific conductance of 1,530 µmhos/cm, down from 2,200 µmhos/cm. This <br /> improvement notwithstanding, the water supply specific conductance before use by the <br /> Discharger is in the range of 470 µmhos/cm to 660 µmhos/cm, so there is approximately <br /> a three-fold increase in water mineralization. <br /> These waste discharge requirements contain a time schedule for installation of additional <br /> groundwater monitoring wells, preparation of an Operation and Maintenance Plan with an <br /> integral cropping plan for the land application areas, and improvements to the land <br /> application areas. <br /> C:Troject FiIn\SitaTal Nat_FroducuVNFO.doc <br />
