Abstract:

During the last two decades, policy makers have ; increasingly recognized that water quality is ; adversely affected by sediment-laden ; stormwater discharge from construction sites. ; On December 1, 2009, the U.S. Environmental ; Protection Agency (EPA) published a rule in the ; Federal Register establishing non-numeric and, ; for the first time, numeric effluent limitation ; guidelines (ELGs). The numeric ELGs included a ; turbidity limit of 280 nephelometric turbidity ; units (NTUs) and sampling requirements for ; stormwater discharges from construction sites ; that disturb 20 or more acres of land at one time. ; EPA’s decision to regulate turbidity through a ; numeric standard was based on the agency’s ; conclusion that turbidity is an “indicator ; pollutant” for identifying other pollutants ; flowing from construction sites. Following ; litigation in April 2013, EPA proposed to ; withdraw the numeric ELG requirement, at least ; for the time being. However, some future ; numeric limits are anticipated in the near future.
