Your good actions can reduce the impact of pollutants on our local waterbodies and help keep them safe for fishing,swimming, surfing and the many other ways that our community enjoys the water.

What is an Illicit Discharge?

An illicit discharge is anything released into a storm drain that is not comprised
entirely of stormwater. Oils, paints, petroleum, chemicals and other liquids,
landscaping debris and sediment, trash and dry weather flow (runoff when no rain event
has occurred) are a few common examples. If you see any illicit discharges along a State
Highway, please report them promptly to the Maui District.

What is an Illegal Connection?

An illegal connection is any unpermitted physical conveyance (pipe, gutter, hose) that
discharges from a private property directly to a storm drain or gutter along a State
Highway.

Examples of What to Report:

ILLEGAL DUMPING

RUNOFF WITH A DISTINCT COLOR OR ODOR

ILLEGAL CONNECTIONS

OIL SPILLS

CONSTRUCTION RELATED RUNOFF

DRY WEATHER FLOW
