PPL = Previous Permit Limit

Flow shall be monitored continuously.  BOD5 and TSS shall be monitored twice per month utilizing a grab sample.  pH shall be monitored daily with a grab sample of the effluent. 

V.	STATEMENT OF BASIS

Permit limits (local limits) were recommended by the Town of Sherman. The facility requests an increase of 0.010 MGD to the current flow limit. An Adequacy of Treatment was performed to determine Sherman POTW could accept the increase in flow from Premier Prints, Inc.
