IDDE Investigations

When a potential illicit discharge is identified — through screening, complaint, or observation — SmartComply manages the entire investigation workflow.

Opening an Investigation

  1. Navigate to MS4 → IDDE.
  2. Click + New Investigation.
  3. Enter:
    • Source — Dry-weather screening, citizen complaint, staff observation, etc.
    • Location — Outfall ID, address, or map pin
    • Initial Observations — Description, color, odor, flow characteristics
    • Photos
    • Field Test Results — pH, chlorine, conductivity, temperature, etc.
  4. Click Open Investigation.

Investigation Workflow

Investigations move through defined stages:

  1. Open — Initial report filed
  2. Field Testing — Additional sampling and upstream tracing
  3. Source Identified — Illicit discharge source located
  4. Enforcement — Corrective action required
  5. Resolved — Discharge eliminated and confirmed
  6. Closed — Investigation complete

Connecting to Annual Reports

IDDE investigation data feeds directly into your MCM-3 annual report section. The system counts investigations opened, resolved, and pending for the reporting period.
