The City of Aurora is issuing this Request for Proposal (RFP) to interested Disposal Facilities for the yearly disposal of approximately 5,000 tons of soil combined with construction and demolition debris that cannot be considered uncontaminated either due to the material having a pH of less than 6.5 or greater than 9.0 or because the material exceeds one or more of maximum allowable concentrations of chemical constituents as defined in 35 IAC 1100 Subpart F. This material is generated by the City during various underground repairs and projects in public rights of way in proximity to both industrial/commercial and residential sites.
