Numerical Effluent Limits for Stormwater Explained
12 December 2011 12:35 PM
A recent blog post by the American College of Environmental Lawyers does a great job of describing numerical effluent limits.
In recent years, the states and EPA have placed greater emphasis on regulating storm water discharges from various industrial and municipal sources under the Clean Water Act. These discharges are typically regulated by a general NPDES Permit issued by EPA or an authorized state. The standard approach required in these general permits is for a facility to develop a storm water pollution prevention plan (SWPPP) incorporating best management practices (BMPs) that will be followed to reduce pollutant impacts to storm water discharged from the facility. Typically some type of periodic monitoring is required during storm events. Turbidity is monitored and often pH. Recently there has been a significant increase in Clean Water Act storm water enforcement actions and third party citizen suits for violation of general storm water permits. Read More...
