What does IDDE mean in UNCLASSIFIED

IDDE stands for Illicit Discharge Detection Elimination. It is the process of identifying, inspecting, and eliminating or controlling non-stormwater discharge sources that are entering the stormwater system. These sources can include discharges from industrial pipes or runoff caused by urban development or improper disposal of solid waste.

IDDE involves a range of activities, including but not limited to identifying potential illicit dischargers; inspecting their facilities and equipment; investigating whether there are any operational practices that could be contributing to illicit discharges; developing appropriate control measures; and ensuring ongoing compliance.

The main purpose of IDDE is to identify and eliminate illicit discharges to protect water quality in receiving bodies. It also helps facilitate better management practices throughout communities that help reduce pollution risks.

Generally speaking, any non-stormwater discharge into a stormwater system may be considered illicit. This includes wastewater from industrial facilities, seepage from underground storage tanks, or used oil leaking from vehicles or equipment. It can also include runoff from construction sites, wash water from pavement cleaning activities, and dumping of raw sewage into drainage systems.

Typically local authorities such as municipal governments or public works departments are responsible for carrying out IDDE activities in their jurisdiction. They usually work with other stakeholders such as local businesses, universities, research centers, environmental organizations and others to identify and resolve illicit discharge issues.

Implementing an effective IDDE program can lead to numerous financial benefits for municipalities including reduced costs associated with treating contaminated water before it reaches receiving bodies; improved water quality which in turn leads to increased recreational opportunities at rivers and lakes; healthier ecosystems which result in increased fish populations; fewer health threats due to contamination; improved public safety due to reduced risk of flooding caused by clogged drains or culverts, among others.

Yes, most countries have some form of regulation governing the prevention, detection and elimination of illicit discharges into stormwater systems. In the United States these regulations stem from both state-level laws as well as the federal Clean Water Act (CWA). The CWA requires that all municipalities have an approved Illicit Discharge Detection & Elimination (ID&D) plan in place prior to receiving funding assistance through EPA grants programs for certain projects designed to improve stormwater infrastructure.

Yes – each sector involved will likely have its own set of best management practices (BMPs) related specifically regarding their operations when it comes preventing pollution associated with their activities being discharged into the storm sewer system. These BMPs may vary based on local geography as well as climate conditions but generally involve some form of prevention like covering manholes/catch basins during storms ; conducting regular inspections and maintenance on catch basins/manholes/culverts ; mitigating erosion appropriately with silt fence barriers etc.
