Mud that leaves your site on tires ends up on the street and in the storm drain, and stormwater permits make it your problem. We source wheel wash stations, rumble plates and stabilized entrances from local providers in the markets we serve, and schedule them with the rest of your site services. Availability varies by market.
What it is
Track-out control is a set of practices at the site exit. Most sites start with a stabilized entrance and add more when mud still gets out.
Street sweeping is the backstop for whatever still reaches the road. Ask us about it for your market.
Common track-out controls
When a job needs it
Track-out control matters most where soil is exposed and trucks leave onto pavement.
Exposed soil and wet weather put mud on every tire that crosses the site.
EPA's construction permit requires stabilization at every exit onto a paved road.
Excavation, demolition and import or export of fill, when trucks come and go all day.
When the city or an inspector has already flagged mud on the street.
The rules
EPA's 2022 Construction General Permit applies where EPA is the permitting authority, to sites that disturb one acre or more or are part of a larger plan that will. Most states run their own permits with similar rules, so check yours.
CGP Part 2.2.4
Restrict vehicles to properly designated exit points, and stabilize every exit onto a paved road. The permit gives aggregate stone over geotextile or non-woven filter fabric, and turf mats, as examples.1
CGP Part 2.2.4
Add track-out controls as needed so sediment comes off before vehicles leave. The permit lists wheel washing, rumble strips and rattle plates as examples.1
CGP Part 2.2.4
Remove sediment tracked onto paved roads, sidewalks or other paved areas by the end of the same business day, or the next business day if it happens on a non-business day, by sweeping, shoveling or vacuuming. Hosing or sweeping it into a drain, inlet or water is prohibited.1
CGP Part 2.3.2
Wheel wash water falls under the vehicle washing rules: minimize pollutants in the discharge, for example by sending it to a sediment basin or trap or through a filter, and keep soaps, solvents and detergents out of it.1
Your stormwater plan should show each exit and the controls at it. See SWPPP site services and erosion control.
Tell us the exits, the trucks and the soil. We source the control that fits each exit.
The options
Controls stack. A stone pad is the usual start, and plates or a wash station go on top where mud still gets out.
| Control | What it does | Usually fits |
|---|---|---|
| Stabilized entrance | A stone pad over fabric that knocks mud off and keeps tires out of the soil | Most sites, as the first control at each exit onto pavement |
| Rumble plates | Steel grates that shake mud loose from the tires | Exits where the stone pad alone is not enough, or where room is short |
| Wheel wash station | Sprays the tires, with the water collected and managed | Heavy clay, wet seasons, long haul phases or strict local rules |
| Street sweeping | Removes sediment that still reaches the road | Every site, as the backstop when track-out happens |
A wheel wash needs water. If the exit has no supply, water delivery can fill it.
How it works with Detritus
You get one point of contact. A local provider supplies and maintains the controls.
The address, the exits trucks use, the traffic and the soil.
The right control for each exit, quoted with your other site services.
The provider sets the plates or the wash station, or builds the stone pad.
Pads get topped up and plates and wash pits get cleaned as sediment builds. Call us when it needs service.
The equipment comes out when the site no longer needs it.

Tell us about each exit. The answers decide whether a stone pad is enough or a wash station is worth it.
Common questions
Mud, soil and sediment carried off a construction site on vehicle tires onto paved roads, sidewalks and other paved areas.
Not always. EPA's construction permit requires stabilized exits onto paved roads and more controls as needed, and lists wheel washing, rumble strips and rattle plates as examples. Your state permit or local rules may ask for more.
Under EPA's construction permit, by the end of the same business day, or by the end of the next business day if it happens on a non-business day.
Not into a drain. The permit prohibits hosing or sweeping tracked-out sediment into any site drainage feature, storm drain inlet or receiving water.
It has to be managed so pollutants are minimized, for example by sending it to a sediment basin or trap or through a filter, with no soaps, solvents or detergents in the discharge.

Local providers do the work. We source them, schedule them with your other site services and send one bill.
