New Stormwater Guidelines for Construction Sites

Beginning February 1, 2010 the EPA began enforcing new stormwater runoff standards for construction sites disturbing an acre of land or more. The new regulations are meant to ensure that precipitation does not cause erosion or wash construction materials, chemicals, and solvents into nearby waterways. Runoff from construction sites has negative effects on water quality and can heavily impact the health of aquatic ecosystems.

This is the first of a series of tightened stormwater pollution regulations. Starting August 1, 2011 the EPA will also require construction sites to sample stormwater discharges to gage pollutants in runoff and may also, depending on the outcome of ongoing legislation, require turbidity limits as well. Also going into effect on August 1, 2011 are requirements for construction companies disturbing 20 or more acres to meet a series of non-numeric effluent limitations. This means that builders will be required to: control erosion and sediment to minimize the discharge of pollutants; stabilize soil during clearing, grading, and other earth-disturbing activities; dewater trenches and excavations; minimize pollution from wastewater, pesticides, herbicides, and other harmful chemicals. Discharge of wastewater from the washout of concrete is prohibited.
