EPA Issues Correction of Construction Stormwater Reg
03.09.10 5:10 PMYesterday, the EPA corrected its December 1, 2009, Federal Register notice for the final construction stormwater rule found at 74 FR 62995 to reflect the correct date of applicability as August 2, 2011. The Federal Register notice stated that the compliance dates for the turbidity limitation for sites that disturb 20 or more acres of land at one time was set to begin 18 months after the effective date of the rule. The notice mistakenly stated that the applicable date was August 1, 2010, NOT August 2, 2011.
As a refresher, the EPA issued its Final Rule for “Effluent Guidelines for Discharges from the Construction and Development Industry" at the end of 2009. The rule significantly affects construction projects that disturb 10 acres or greater at any one time. One of the most significant and controversial provisions is a numeric limitation for turbidity- the rule requires average daily turbidity for discharges to not exceed 280 Nephelometric turbidity units (Ntu).
