Construction activities are known to rapidly increase the erodibility of soils. The increase in soil erosion can have a detrimental effect on surface waters. Soil leaving a construction site can enter a storm sewer system which ultimately leads to area lakes, wetlands, streams and rivers. The sediment that flows to these waterways, from construction sites , is sometimes contaminated with fertilizers, pesticides, or other substances like oils or grease that are associated with construction activities. Therefore, it is important that we work to maintain all soils on site to ensure the health of our local surface waters.
Construction sites with any type of land disturbing activity are required to prevent or reduce all of the following:
- The deposition of soil from being tracked onto streets by vehicles.
- The discharge of sediment from disturbed areas into on-site storm water inlets.
- The discharge of sediment from disturbed areas into adjacent waters of the state.
- The discharge of sediment from drainage ways that flow off the site.
- The discharge of sediment by dewatering activities.
- The discharge of sediment eroding from soil stockpiles existing for more than 7 days.
- The discharge of sediment from erosive flows at outlets and in downstream channels.
- The transport by runoff into water of the state chemicals, cement, and other building compounds and materials on the construction site during the construction period.
