Washington, DC (February 1, 2009)- The U.S. Environmental Protection Agency (EPA) recently proposed guidelines to control the discharge of pollutants from construction sites. The proposal would require all construction site managers to implement erosion and sediment control best management practices to reduce pollutants in stormwater discharges.
In addition, for certain large sites located in areas of the country with high rainfall intensity and soils with high clay content, stormwater discharges from the construction site would be required to meet a numeric limit on the allowable level of turbidity, which is a measure of sediment in the water. In order to meet the proposed numeric turbidity limit, many sites would need to treat and filter their stormwater discharges.
This proposal, if implemented, would significantly reduce the amount of sediment and other pollutants discharged from construction sites. EPA estimates that this proposed rule would cost $1.9 billion dollars per year with annual monetized benefits of $332.9 million. This proposed rule requests comment and information on the proposed regulation and an alternate option with a different numeric limit based on different technologies, as well as specific aspects of the proposal such as technologies, costs, loading reductions and economic achievability.
Comments must be received on or before February 26, 2009.
