Illicit Discharge Detection and Elimination (IDDE) Program

ILLICIT DISCHARGES AFFECT EVERYONE...EVEN YOU!

Definition of Illicit Discharge

An illicit discharge is any discharge to a municipal separate storm sewer system that is not composed entirely of stormwater runoff except discharges from common residential outdoor uses, firefighting activities, or from any legally permitted discharge.  In the event an activity is found to discharge sewage, industrial waste, or other waste into the storm sewer system, the County shall notify the person performing such activities, and shall order such activities be stopped or conducted in such a manner as to avoid the discharge of sewage, industrial wastes, or other wastes into the storm sewer system.  The County’s regulations regarding Illicit Discharge are located in the Storm Drainage Ordinance, Section 19.2.

Charles County’s IDDE Program

The County conducts an annual random screening of stormdrain outfalls as well as a routine survey of commercial and industrial watersheds.  The overall goal of the IDDE program is to identify illegal dumping activities, unauthorized storage of materials and illicit discharges.  By identifying such activities and having specific reports for a violation, the County proceeds with efforts to remove such unpermitted discharges.
