Summary
County code bars overfilling a mobile/roll-off waste container used for demolition or construction debris, requires full containers be pulled promptly, and mandates wind-secure loads.
No person shall store in or place additional demolition and construction waste in a mobile/roll-off waste container which is full. A mobile/roll-off waste container is full if no more waste can be added to it without making it unsafe to transport, filled in excess of the rated capacity, or in excess of established public roadway weight limits. ... Demolition and construction waste shall not be stored in a floodplain unless it is stored in a mobile/roll-off waste container.

Full Breakdown
Section 240.345 of the county's Solid Waste Management Code, which governs unincorporated St. Charles County, prohibits adding more demolition or construction waste to a mobile/roll-off container once it's full, meaning unsafe to add to, over rated capacity, or over roadway weight limits. Whoever requested the container be placed must have a full one hauled away and the waste deposited at an appropriate facility, debris must be secured against wind dispersal, and containers stored in a floodplain must be enclosed roll-off units rather than open piles.
Violations & Fines
Leaving a full roll-off container onsite draws a $100 fine for a first offense and $300 for repeat violations; failing to secure demolition debris against wind carries the same $100/$300 schedule under Section 240.1750.
