The proposed wastewater treatment and disposal system consists of(a) a 1,200 gallon, two- compartment, grease trap that will receive industrial waste from the manufacturing floor drains, wash sinks, cooling tables, and washing machine; (b) a 2,000 gallon, single-compartment, septic tank that will receive domestic waste from the 14,200 sq. ft. building and the existing 1,600 sq. ft. building, and (c) a secondary 2,000 gallon, two-compartment, settling tank containing a septic tank effluent pump. The settling tank will receive the waste from both the industrial grease trap and the domestic septic tank. Wastewater will be pumped from the secondary settling tank to one of two disposal systems: an 1,800 sq. ft. filter bed area equipped with 22 laterals protected by Infiltrator chambers, or two 40 ft. long leachlines with 16 ft. deep seepage pits at the terminal ends. A schematic of the system is presented on Attachment B, which is attached hereto and made part of this Order by reference. 7. Untreated wastewater quality is estimated in the RWD as follows. It is noted that the untreated wastewater quality is based on the result of one composite sample, and may not represent maximum concentrations. It is also noted that the Discharger did not provide the anticipated concentration of total dissolved solids in the effluent. Anticipated Untreated Typical Untreated Constituent Units CDD Wastewater uali ' Domestic Wastewater2 BOD mg/L 577 210 Total Nitrogen mg/L 36 35 TSS mg/L 268 210 1 Wastewater quality from Table 3, 11103 RWD, includes a mixture of domestic and industrial wastewater. 2 Domestic wastewater values from Table 4-14 Small and Decentralized Wastewater Management Systems, 1998. 8. Wastewater will be discharged to a shallow leachfield system. Septic tank effluent will be pressure dosed to the leachfield using an Orenco Biotube Pump Vault or equivalent. The Biotube is equipped with a filter cartridge to prevent discharge of solids to the leachfield/seepage pits. 9. Disposal will primarily be accomplished through evapotranspiration and infiltration. The dispersal area will be landscaped to allow shallow rooted plants to take up nitrogen. Plants will be selected to prevent intrusion of roots into the infiltrators, leachlines, or seepage pits.
