Concentration limits are <br />also specified in the NPDES permit. Figure 5.1.3-3 illustrates the anticipated maximum week <br />CBOD and TSS concentrations that result from projected flows and tmchanged mass <br />limitations as specified in the existing NPDES permit. These are shown relative to the <br />anticipated concentration limits. Percent removal limits do not apply on a maximum week <br />basis. <br /> <br />5-6 MWMC 5.0 REV&DOC <br /> <br /> <br />
