Pollution Prevention for Construction Sites

Construction activities can have a significant impact on water quality if not properly managed. To minimize these risks, implementing Best Management Practices (BMPs) is essential.

BMPs are practical, effective methods designed to control erosion, manage runoff, and reduce stormwater pollution during construction activities. By adhering to these practices, construction teams can not only comply with local, state, and federal regulations but also contribute to the protection of our environment and community resources. Whether you're a project manager, contractor, or site worker, understanding and applying these principles is critical for maintaining a sustainable and responsible construction site.

Construction wood covered with plastic sheeting and sandbags

All building materials must be contained and covered.

- Materials must be stored on-site at all times unless an encroachment permit has been obtained.

Portable Toilets
Concrete Trucks/Pumpers
Tracking Controls

Close up of portable toilet with plastic containment tray

Secondary containment trays are recommended for all portable toilets.

NEVER stage in street, gutter pan or over/near storm drains.

Service regularly.

Washout Area
Dirt and Grading
Storm Drains

Large metal bin labeled "Paint Washout Only"

The disposal of “wet” construction materials should be handled in the washout area. This includes paint, stucco and concrete.

Use a berm and/or plastic sheet to collect and contain liquids and prevent run-off in nearby areas.

Permitting/Compliance

Federal, state, local regulation; regional codes; and local ordinances prohibit any discharge, other than storm water, into the storm drain system.
The property owner is responsible to know and follow all state, regional, and local requirements and guidelines, including obtaining proper permits, for all work to be completed. Work must comply with all applicable conditions, regulations, and requirements.

Be Rain Ready

Check the weather prior to performing any outdoor activity. Avoid work in the rain.
Be prepared to cover exposed surfaces prior to any potential rain event. Have a plan and supplies on-site.
Routine, periodic and storm event triggered inspections are needed to:
- Identify non-storm water discharges
- Determine BMP effectiveness
- Identify necessary repairs or BMP changes.
Keep gutters clear for flow. Large scale construction projects must have a Storm Water Pollution Prevention Plan (SWPPP).

Spills (including mud, dirt, silt)

Create a plan for addressing hazardous and non-hazardous spills. Make sure people on your site know how to respond.
Keep spill clean-up materials on-site (absorbents, rags, etc.).
Report spills immediately.
Never hose down “dirty” pavement or surfaces. Clean up all spills and leaks using “dry” methods (with spill absorbents or comparable materials such as sawdust, cat litter, and/or rags). Sweep areas daily.
