Public Works Memorandum <br /> NO. 2010-29 <br /> DATE: June 9,2010 <br /> TO: Honorable Mayor McElroy and City Council <br /> FROM: Ryan P. McCrady, City Manager <br /> Richard G. Marley, P.E.,Director of Public Works <br /> SUBJECT: Ground Water Ordinances for Various Locations in the City of Decatur <br /> SUMMARY RECOMMENDATION: <br /> It is recommended by staff that the City Council approve the attached Ground Water Ordinances <br /> prohibiting the use of groundwater as a potable water supply for the following sites: <br /> 1. Speedway Super America site at 3798 North Woodford Street <br /> 2. Circle K#151 site located at 501 North Main Street <br /> 3. Strip Mall site located at 2192 through 2952 North Martin Luther King, Jr. Drive <br /> PRIOR COUNCIL ACTION: <br /> There have been no prior Council actions regarding ground water contamination at the specific <br /> sites identified in this transmittal. <br /> Prior Council Action on Ground Water Ordinances: <br /> Since 2002,the City Council has authorized 11 ground water ordinances at various locations in <br /> the City. <br /> BACKGROUND: <br /> Ground Water Ordinance: <br /> City staff was contacted by representatives of each site under consideration regarding their <br /> remediation efforts resulting from leaking underground storage tanks on their properties. A <br /> Ground Water Ordinance is a tool used by the Illinois Environmental Protection Agency (IEPA) <br /> to remediate properties where soil and ground water under the site have been contaminated by <br /> leaking underground storage tanks. The ordinance prohibits the use of groundwater as a potable <br /> water supply within the area identified on Exhibit A (attached to each ordinance) as having the <br /> maximum potential for ground water contamination from gasoline released from the various <br /> sites. <br /> The major benefit of a ground water ordinance is that it will serve to keep contaminated water <br /> isolated underground and not allow it to be used for human consumption. Ground water use <br /> prohibition areas within the City are generally served by the City's public water supply so the <br /> prohibition should not create a hardship on area residents or businesses. <br /> Page I 1 <br />
