0 +� <br /> INFORMATION SHEET <br /> ORDER NO, 5-01-148 <br /> FOX VALLEY CORPORATION <br /> FOX RIVER PAPER COMPANY <br /> RIPON MILL <br /> SAN JOAQUIN COUNTY <br /> Fox River Paper Company(owned by Fox Valley Corporation, Appleton, Wisconsin) operates a <br /> paper mill within the city limits of Ripon, San Joaquin County. The Ripon Mill manufactures <br /> several grades of fine papers from purchased pulp. The mill's maximum daily production rate is <br /> 200 tons of paper. <br /> The Ripon Mill discharges a maximum 2.5 mgd of combined industrial waste water and storm <br /> water runoff from primary and secondary treatments to 98 acres. The mill facility occupies 228 <br /> acres. <br /> Prior to July 1975, the Ripon Mill discharged to the Stanislaus River continuously or <br /> intermittently. Since July 1975, the mill has been able to contain all wastewater on land. The <br /> Ripon Mill no longer discharges wastewater into the Stanislaus River. The discharge of <br /> wastewater to the Stanislaus River or any other surface water or drainage course is prohibited. <br /> The Ripon Mill has reduced the amount of salts in their discharge. These changes include using <br /> a distillation process to concentrate water softener regeneration waste in order to make it <br /> acceptable as brine for commercial use off-site; altering the process chemistry to reduce alum <br /> consumption, and installing new process water supply wells screened in an aquifer that has less <br /> dissolved salts. These changes are reducing the amount of salts in the final effluent to the <br /> percolation ponds. <br /> The Ripon Mill will continue to conduct pond and ground water monitoring to confirm that the <br /> discharge is not degrading ground water. Additionally, Ripon Mill will be required to conduct a <br /> ground water study every five years to determine the effectiveness of the operational and <br /> wastewater management changes on reducing the amount of salts in the discharge and the overall <br /> impact to the aquifers below the site. Based on the data provided through their monitoring <br /> program a final determination on the wastewater classification will be made. <br /> Waste sludge contained within an inactive impoundment has been demonstrated to be an inert <br /> waste and the mill will close the impoundment according to their Closure Plan during 2001. <br /> WWA: /14 June 2001 <br />
