Nearly a year after finalizing its construction stormwater rule, in response to objections from industry groups, EPA has conceded that the controversial numeric turbidity limit in the rule is flawed. EPA issued the final construction stormwater effluent guidelines rule[1] (the “Rule”) in December 2009, for the first time establishing a numeric limit on the turbidity of stormwater discharges from large construction sites and requiring monitoring to ensure compliance with the numeric limit. The Rule also required nearly all construction sites that obtain stormwater permits after February 1, 2010 to implement a range of erosion and sediment controls and pollution prevention measures. EPA’s Rule elicited immediate criticism, including a lawsuit brought by industry groups in the Seventh Circuit,[2] and a petition for administrative review by the Small Business Administration (“SBA”) Office of Advocacy.

Lessons in Solving Big Weather-Related Problems

When it comes to controlling erosion and sediment in bad weather, construction of a third runway at Seattle-Tacoma International Airport, near Seattle, WA, qualifies as a genuine challenge. Providing a foundation for the 8,500-ft.-long, 150-ft.-wide runway in the hilly terrain will require an estimated 17 million yd.3 of fill. Since construction began in 1997, about 5 million yd.3 have been placed. It will take a large fleet of dump trucks, running 20 hours a day, three and a half years to bring in the rest. Then there’s all that wet weather the area is famous for, especially in late fall and winter. Two years ago, for example, the project was drenched with about 5 in. of wind-driven rain in one 36-hour period. (more…)
