DATE: September 25, 2023
SUBJECT:
A resolution authorizing the Director of Purchasing to execute a contract agreement supplement with Fehr Graham & Associates, LLC in the amount of $22,000.00 for monthly CSO Monitoring and DMR Reporting.
PURPOSE:
To continue the City's professional services agreement with Fehr Graham for the remainder of 2023 to provide Combined Sewer Overflow (CSO) structure monitoring and Discharge Monitoring Reports (DMR).
BACKGROUND:
As part of the Clean Water Act, the Environmental Protection Agency created the National Pollutant Discharge Elimination System which resulted in several permits for the City of Aurora. As part of one of these permits, the City was required to create a Long-Term Control Plan (LTCP) to reduce pollutants entering the Fox River and Indian Creek from their combined sewer systems. Monthly Discharge Monitoring Reports for each Combined Sewer Overflow structure are required to be submitted to the IEPA and USEPA as part of the City's permit.
Flow meters have been strategically placed at each of the City's 16 CSO's to capture the required data needed to create the monthly DMR's. Twice a month, Fehr Graham retrieves flow meter data from each structure and also provides meter maintenance including cleaning the sensors and replacing the batteries. Fehr Graham uses the data collected from the flow meters to calculate volume of discharge and duration of flows.
Fehr Graham also collects rainfall data at their Aurora office rain gauge which is used in the DMR report.
The parameters of rainfall totals, rainfall duration, overflow duration and overflow volume are used to create the required monthly DMRs.
DISCUSSION:
The existing contract of $49,900 and supplement for $22,000 can be found in Exhibits A and B, respectively, bringing the total contract amount to $71,900. This project will be completed by the end of December 2023. The total project amount of $71,900 is budgeted for in 2023 within account 510-4063-511-73-13.
IMPACT STATEMENT:
Minimal traffic disruptions are expected during data retrieval. Impacts to traffic and local residents will be kept to a minimum.
RECOMMENDATIONS:
I request the proposed resolution be adopted.
