North Side WRP
NPDES Permit No. IL0028088
CSO Monitoring and Reporting Plan
September 1, 2002
Rev. August 22, 2005

 

In accordance with Special Condition 10.11 of the North Side National Pollutant Discharge Elimination System (NPDES) Permit No. IL0028088 effective March 1, 2002, the following plan is being submitted for monitoring the frequency and duration of the discharge from select, representative CSO outfalls authorized in the permits and for all other CSO outfalls connected to TARP, for which the Metropolitan Water Reclamation District of Greater Chicago (District) has the ability to monitor through telemetry.

 

The 57 CSO outfalls listed below will be monitored as required in SC 10.11.  They include all CSOs for which the District has the ability to monitor through telemetry.  This list has been updated to account for multiple outfalls associated with each dropshaft/TARP structure.

 

The District will document the frequency and duration of CSOs through the outfalls listed below along with an estimate of storm duration and total rainfall for each storm event.  The District will continue to monitor these designated CSO outfalls at all times unless the telemetry is out of service due to malfunction or routine maintenance.  The results of the monitoring will be submitted to the IEPA by November 15th of each year.
