Illicit Discharge Detection and Elimination

In December 1996, the Program developed the Illicit Connection and Illegal Dumping (IC/ID)
Performance Standards to effectively eliminate non-permissible non-storm water discharges associated with illegal dumping or illicit connections to the storm drain system. Each Co-permittee has developed an Urban Runoff Management Plan that describes its agency-specific local strategy and includes tailored IC/ID Performance Standards, Best Management Practices (BMPs) and Standard Operating Procedures (SOPs).

In October 2000, the performance standards were updated to include conducting inspections and reporting the presence of stormwater infiltration devices (SWIDs); and reporting significant conditionally exempt discharges that are not properly managed. To address provisions within the Program’s NPDES permit, the performance standards were updated in February 2005 to include enhanced reporting and program effectiveness evaluation requirements.

Co-permitees continue to implement the IC/ID Performance Standards by responding to illicit discharges and illegal dumping incidents, conducting proactive investigations and initiating enforcement actions against responsible parties. To supplement individual Co-permittee IC/ID inspection data, Program staff prepares IC/ID incident summary tables for Co-permittee inspections that have occurred the previous fiscal year. Co-permittee IC/ID incident summary tables for FY 08-09 are provided here. Each year, IC/ID incident summary tables are included within Appendix G of the Program’s Annual Report.
