MWMC FACILmES PLAN <br /> <br />addition to the water quarry limits, DEQ has provided standards for the minimum <br />monitoring required for total coliform and turbidity based on the four categories. <br />Table 5.1.5-1 summarizes the treatment and monitoring requirements for the four reuse <br />categories. DEQ may include additional permit effluent limitations and/or other permit <br />conditions other than those shown in Table 5.1.5-1 if they have reason to beheve that the <br />reclaimed water may contain physical or chemical contaminants that would impose <br />potential hazards to the public or environment. <br /> <br />TABLE 5.1.5-1 <br />Treatment and Monitoring Requirements for Use of Reclaimed Water <br />MWMC Facilities Plan, Eugene-Springfield <br /> <br /> Category Level I Level II Level III Level IV <br />Biological Treatment X X X X <br />Disinfection X X X <br />Clarification X <br />Coagulation X <br />Filtration X <br />Total Coliform (organisms/100 mL): <br />Two Consecutive Samples N/L 240 N/L N/L <br />7-Day Median N/L 23 2.2 2.2 <br />Maximum N/L N/L 23 23 <br />Sampling Frequency N/R 1 per week 3 per week I per day <br />Turbidity (NTU): <br />24-Hour Mean N/L N/L N/L 2 <br />5% of Time During a 24-Hour Period N/L N/L NIL 5 <br />Sampling Frequency Hourly <br />General <br /> <br />Public Access Prevented Controlled Controlled No direct <br /> (fences (signs, (signs, public <br /> gates, rural or rural or contact <br /> locks) nonpublic nonpublic during <br /> lands) lands) irrigation <br /> cycle <br /> <br />General Requirements <br />A number of general requirements have been outlined in DEQ's Chapter 340 Division 55 <br />rule. These requirements address agricultural and nonagricultural uses that are acceptable <br />based on the effluent water quality level, irrigation system, public access requirements, and <br />buffer zones for irrigation. Table 5.1.5-2 summarizes these general requirements based on <br />the different levels of reclaimed water quality. <br /> <br />5-18 MWMC_5.0_REVB_VKS.DOC <br /> <br /> <br />
