MWMC FACIUTIES PLAN addition to the water quality limits, DEQ has provided standards for the minimum monitoring required for total coliform and turbidity based on the four categories. Table 5.1.5-1 summaries the treatment and mordtoring requirements for the four reuse categories. DEQ may include additional permit effluent 1/mitations and/or other perrrdt conditions other than those shown in Table 5.1.5-1 if they have reason to believe that the reclaimed water may contain physical or chemical contaminants that would impose potential hazards to the public or environment.

These requirements address agrioaltural and nonagricultural uses that are acceptable based on the effluent water quality level, irrigation system, public access requirements, and buffer zones for irrigation. Table 5.1.5-2 summar/zes these general requirements based on the different levels of reclaimed water quality. 5-18 MWMC_5.0_REV~_VKS DOC
