CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> ORDER NO. <br /> WASTE DISCHARGE REQUIREMENTS <br /> FOR <br /> FOX VALLEY CORPORATION <br /> AND <br /> FOX RIVER PAPER COMPANY <br /> RIPON MILL <br /> SAN JOAQUIN COUNTY <br /> The California Regional Water Quality Control Board,Central Valley Region, (hereafter Board) T' <br /> finds that: <br /> 1. Fox Valley Corporation and Fox River Paper Company, Ripon Mill, (hereafter Discharger) E <br /> submitted a Report of Waste Discharge, dated 17 June 1996, to increase discharge of waste <br /> water from 30 million gallons per month, based on an operating schedule of 20 days per <br /> month,to 60 million gallons per month with a daily maximum of 2.5 million gallons. The N <br /> increased flows are based on an operating schedule of 30 days per month. The Discharger <br /> proposes the continued discharge of waste water to on-site ponds and adjacent percolation <br /> fields. <br /> 2. The Discharger operates a paper mill in Section 29,T2S, R8E, MDB&M, as shown on <br /> Attachment A, which is incorporated herein and made part of this Order. The Discharger A <br /> discharges a maximum 2.5 mgd of combined treated industrial waste water, and storm water <br /> runoff to 98 of 228 acres owned by Fox River Paper Company (APN No. 259-340-01 and <br /> 259-340-02) for disposal by percolation and irrigation fields. The discharge areas are shown <br /> on Attachment B, which is incorporated herein and made part of this Order. Domestic waste <br /> is sewered to the City of Ripon waste water treatment facilities. <br /> I <br /> 3. The Discharger manufactures several grades of fine papers from purchased pulps which <br /> includes virgin bleached pulp,deinked post-consumer waste, and waste paper(secondary <br /> fiber). The mills maximum daily production rate is 200 tons of paper. Process water is `I <br /> added to bales of pulp to make a pulp slurry which is made into paper. Dyes, starches, <br /> rosins,inorganic materials, such as clay and titanium dioxide and alum, are also added to the <br /> slurry during the papermaking process. The water that drains from the paper("white E <br /> water"),is recycled to be used in the makeup of additional pulp slurry. The "white water" <br /> holding tank and stock chests are dumped when colors are changed which may be as often as <br /> 2 to 3 times per day. Periodically, (once a month) the entire paper machine system is cleaned <br /> ("boiled out") with a caustic solution. The spent caustic is commingled with other mill <br /> effluent and discharged to the clarifier. Waste water effluent to the clarifier from the <br /> papermaking process averages 1.0- 2.0 mgd. <br /> 4. Low conductivity regeneration brine from the cogeneration plant water softeners and the mill <br /> effluent are collected in a sump and discharged into a circular primary clarifier. The clarifier <br /> effluent is discharged into two aeration stabilization basins (ASB) in series, as shown on <br /> Attachment B, The first ASB No. 1 is a 14-foot deep lined basin converted from an <br /> abandoned sludge pit. The second ASB No. 2 is an unlined 5-foot deep basin. Effluent <br /> from ASB No. 2 is disposed of on-site to percolation and irrigation fields through a system <br /> of pumps and irrigation pipelines. The original No. 1 and No. 3 effluent ponds (renamed as <br /> Overflow Ponds No. 1 and No. 2) have been removed from the waste water treatment <br />
