United States Environmental Protection Agency Office of Water 4303T EPA 821-F-10-001 March 2010 vvEPA Fact Sheet Correction Notice: Effluent Guidelines for Discharges from the Construction and Development Industry Summary The U.S. Environmental Protection Agency (EPA) is correcting compliance dates that were incorrectly presented in the December 2009 final effluent limitations guidelines (ELGs) and new source performance standards (NSPS) to control the discharge of pollutants from construction sites. Background Construction activities like clearing, excavating, and grading significantly disturb the land. The disturbed soil, if not managed properly, can easily be washed off of the construction site during storms and enter water bodies. Stormwater discharges from construction activities can cause an array of physical, chemical and biological impacts. About This Correction EPA promulgated ELGs and NSPS to control discharges from construction activities on December 1, 2009 (74 FR 62996). The final rule requires permittees at certain construction sites to collect samples of stormwater discharges and to comply with a numeric turbidity limitation. As published, the preamble to the final rule and the final rule contain an error with respect to the compliance dates. Sites that disturb 20 or more acres of land at one time are required to conduct sampling of discharges and comply with the numeric limitation for turbidity beginning on August 1, 2011. The preamble to the final rule at page 63050 and the final rule at §450.22(a) incorrectly state this date as August 2, 2010. The correction does not affect the compliance date for sites that disturb 10 or more acres of land at one time. This date remains as February 2, 2014.
