When are the Storm Water Regulations triggered for construction activity?
Generally, when construction activities disturb five (5) or more acres storm water regulations are triggered. Also, small sites are additive. In other words, if you have five (5) one (1) acre sites which may or may not be adjacent to one another, but are covered under a single construction plan, development or sale, the regulations apply to all those individual construction site activities. Be aware that, in certain situations, EPA may require permit coverage for construction activities of less that five (5) acres if deemed necessary by the Regional Administrator. Also, EPA has a proposed rule under the phase II storm water program that may regulate construction sites between one (1) and five (5) acres in size. The storm water regulations applicable to federal permit coverage are published as notices in the Federal Register. Like other CWA permits, federal storm water permits are renewed on a five (5) year basis. A general permit for construction activity was reissued on 2/17/98 (63 FR
