Preparing for EPA Effluent Limitation Guidelines

On December 1, 2009, the US Environmental Protection Agency (EPA) finalized and published a rule in the Federal Register establishing non-numeric and, for the first time, numeric effluent limitation guidelines (ELGs). The numeric ELGs include turbidity limits and sampling requirements for stormwater discharges from construction sites. All sites that disturb 20 or more acres of land at one time are required to comply with a turbidity limit. The EPA is requiring Texas to implement these new requirements when the Texas Commission on Environmental Quality (TCEQ) next renews the Texas Construction General Permit (CGP). Three research institutes (Texas Transportation Institute, The University of Texas at Austin and Texas Tech University) will collaborate on this project to cover the statewide differences in climate, soil types, slopes, and other factors that affect the performance of erosion control measures.
