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 /> '_W tons of paper. <br /> The Ripon Mill proposes to discharge a maximum 2.5 mgd of combined industrial waste water and <br /> storm water runoff from primary and secondary treatments to 98 acres- The mill facility occupies <br /> 228 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 wasze Rater on land. The <br /> Ripon Mill no longer discharges waste water into the Stanislaus River. The discharge of waste <br /> water to the Stanislaus River or any other surface water or drainage course is prohibited. The <br /> Ripon Mill has applied for the waste discharge requirements,covering a discharge of waste to land <br /> in place of their discharge to surface waters. The Ripon Mill has proposed several changes to <br /> reduce the amount of salts in their discharge. These changes include using a distillation process to <br /> concentrate water softener regeneration waste in order to make it acceptable as brine for commercial <br /> use off-site; altering the process chemistry to reduce alum consumption_ and installing new water <br /> supply wells screened in an aquifer which have less dissolved salts. TIL--se changes should reduce <br /> the amount of salts in the final effluent to the percolation ponds,such that the level of salts in the <br /> discharge will not degrade water quality beneath the site. <br /> Ripon Mill's consultant. David A. Lawrence, C.E.G. 618,has certified chat.Ripon Mill discharge <br /> is not a 'designated waste'. The Ripon Mill will conduct pond and ground xater monitoring to <br /> confirm that the discharge is not impacting ground water. Additionally_Ripon Mill wili be <br /> required to conduct a ground water study every five years to determine rbe effectiveness of the <br /> operational and waste water management changes on reducing the amount of salts in the discharge <br /> and the overall impact to the aquifers below the site. <br /> PWM:dlk/9 August 1996 <br />
