On September 2, 2009, the State Water Resources Control Board (“State Board”) adopted a new General Permit for Discharges of Storm Water Associated with Construction Activities (“CGP”) that imposes significant new and potentially burdensome requirements for discharging storm water from construction sites. The CGP would apply to all construction activities disturbing one or more acres of land or to smaller areas that are part of a common plan for development, as well as to construction activities related to linear overhead/underground projects, which were previously covered under a separate general permit. Unless the CGP is challenged and set aside, the new permit will become effective on July 1, 2010, allowing current dischargers to get through the 2009-2010 rainy season before the new standards go into effect.
