t � OF'�FC �= C v �o �i♦�%9 '/[LINO\S October 7, 1999 PUBLIC WORKS MEMORANDUM NO. 99 - 62 MEMORANDUM TO: Honorable Mayor and City Council FROM: Rolanda A. Johnson, Acting City Manager � Bruce A. McNabb, P.E., Director of Public Works John A. Smith, Water Production Manager SUBJECT: South Water Treatment Plant � Nitrate Design Engineering Services, City Project 9953 The City of Decatur has signed a Letter of Commitment with the Illinois Environmental Protection Agency (IEPA) to be in compliance with the 10 mg/1 maximum contaminant level for nitrates by April 15, 2001. The Mayor, City staff, and others met recently with representatives of US and Illinois EPA concerning the 10 mg/1 nitrate standard and the compliance deadline. Although EPA is willing to work with the City on meeting the compliance deadline, they will not change the 10 mg/1 standard. Therefore, the City should begin the design work for water plant equipment to reduce nitrate levels in the City's drinking water as soon as possible. Staff has negotiated an agreement with Black & Veatch for this project. A copy of the Agreement is attached. Black and Veatch was chosen for this work based on their design and subsequent work at the South Water Treatment Plant, and due to their ion exchange design experience (summary attached). The design work should take about 270 days (nine months) to complete and cost $640,000, which includes expenses. The majority of the funding will come from a $500,000 IEPA grant and the remainder and come from the South Water Treatment Plant Bond Fund. During the design period, City staff will work with IEPA to extend the compliance deadline. It is recommended by staff that City Council approve the attached resolution awarding a contract to Black & Veatch for the South Water Treatment Plant Nitrate Design, City Project 9953, and authorize the Mayor to execute the Agreement. attach.: 3 cc: Sam Wolfinbarger, Black&Veatch
