The two most common sources of stormwater pollution problems associated with construction activities are erosion and sedimentation. Failure to maintain adequate erosion and sediment controls at construction sites often results in sediment discharges into the storm drain system, creating multiple problems once it enters local waterways. Construction vehicles and heavy equipment can also track significant amounts of mud and sediment onto adjacent streets. Additionally, wind may transport construction materials and wastes into streets, storm drains, or directly into our local waterways. As a contractor, site supervisor, owner or operator of a site, you may be held responsible for the environmental damage caused by your subcontractors or employees. Following these construction BMPs will enable your company to reduce stormwater pollution.
The following BMPs can help reduce pollutant discharges from your construction site. Compliance with stormwater regulations can be as simple as minimizing stormwater contact with potential pollutants by providing covers and secondary containment for construction materials and implementing good housekeeping practices at the construction site.
The Nevada Division of Environmental Protection (NDEP) adopted the General Permit for Stormwater Discharges Associated with Construction Activity (NVR100000). The General Permit for Construction Activity establishes a number of stormwater management requirements for construction site owners and operators over 1 acre. This permit is administered and enforced by the NDEP, with cooperation from local municipalities that have their own ordinances controlling discharges to the drainage system.
