GILOT~ P.E. <br />DIRECtOR OF PUBLIC WORKS <br />October 2, 2000 <br />Ms. Charlotte Pfeifer <br />President, Common Council <br />of the City of South Bend <br />400 County City Building <br />South Bend, IN 46601 <br />PHONE 219/235-9251 <br />Fax 219/235-9171 <br />TDD 219/235-5567 <br />RE: Ordinance Amending Chapter 17 of the South Bend Municipal Code <br />Dear Ms. Pfeifer: <br />Enclosed is a copy of an ordinance to amend portions of Chapter 17 of the South Bend Municipal <br />Code. As noted more specifically in the Ordinance, these amendments are proposed to eliminate <br />monthly averages discharge limits which are not required since the daily maximum limits were <br />amended in 1998. <br />Specifically, there are two major ordinance revisions: 1) elimination of monthly average <br />discharge limits; 2) expansion of the upper pH limit to 11.0. <br />In 1998, the U.S. EPA suggested the City revise its local discharge limits by deriving new limits <br />through a process known as Headworks Loading Allocation. This is a technical approach <br />arriving at limits specifically calculated for South Bend and its sewer users. <br />It was the City's desire at the time (November 1998) to eliminate the monthly average limits and <br />just revise the daily maximum limits, which is the normal approach required by the Headworks <br />Loading Allocation Method. However, it was not possible to meet the time table in November <br />1998 as the removal of the monthly average limits was considered a major modification by U. S. <br />EPA and was subject to public notice requirements. <br />Since November 1998, the City has conducted the public notice process with the U.S. EPA and <br />has received approval from the U. S. EPA to remove the monthly average limits from South <br />Bend's Sewer Use Ordinance. <br /> <br />ENGINEERING ENVIRONMENTAL SERVICES CENTRAL SERVICES STREETS WATER WORKS <br />CARL LITTRELL, P.E.
