Pollutant Reductions

As a result of this settlement, EPA estimates the sediment discharged in stormwater runoff will be reduced annually by 217 million pounds from Toll Brothers sites nationwide, with a reduction of approximately 21million pounds per year within the Chesapeake Bay Watershed.

Health and Environmental Effects

Discharges of stormwater runoff, including runoff from construction sites, can have a significant impact on water quality.  Construction activities alter natural landscapes.  During construction, earth is compacted, excavated and displaced, and vegetation is removed.  These activities increase runoff and erosion, thus increasing sediment transported to receiving waters.  In addition to sediment, as stormwater flows over a construction site, it can pick up other pollutants such as debris, pesticides, petroleum products, chemicals, solvents, asphalts and acids that may also contribute to water quality problems. 

Sediment-laden runoff can result in increased turbidity and decreased oxygen in receiving waters, which in turn results in loss of in-stream habitat for fish and other aquatic species. 
Sediment can kill fish directly, destroy spawning beds, suffocate fish eggs and bottom dwelling organisms, and block sunlight resulting in reduced growth of beneficial aquatic grasses.  In addition, sediment can impact the treatment of drinking water resulting in higher treatment costs, and can result in the loss of drinking water reservoir storage capacity and decrease the navigational capacity of waterways.
