TO: Mayor Richard C. Irving
FROM: L. Eric Schoeny, P.E. Superintendent of Water and Sewer Maintenance
DATE: May 31, 2019
SUBJECT:
A resolution authorizing the Director of Purchasing to adopt unit prices submitted by Waste Management of Illinois for the disposal of excavated spoils that cannot be classified as Clean Construction Demolition Debris (CCDD).
PURPOSE:

The City of Aurora's Water and Sewer Maintenance Division regularly generates excavated spoils while maintaining the City's water and sewer infrastructure. Environmental Science professional services are required to classify excavated spoils for proper disposal. Depending on the results of the soils analysis, spoils are disposed of as CCDD, non-special waste or special waste.
DISCUSSION:
On May 1, 2019, the City's Purchasing Division advertised a request for proposals for the disposal of non-CCDD material. On May 15, 2019, the Purchasing Division opened proposals from two landfill operators. The proposals were evaluated based on per ton dumping costs, trucking expenses, and costs to comply with landfill specific testing requirements.
As shown on the attached evaluation spreadsheet, Waste Management of Illinois's Dekalb site is the most economical disposal facility. The per ton prices are valid for 12 months.
Local preference does not apply to this proposal.
Funding for this expense is provided in the 2019 budget in account 510-40...
