Construction Site Requirements
In 1990, the Environmental Protection Agency (EPA) required National Pollution Discharge Elimination System (NPDES) permit coverage for storm water discharges from construction activities that disturbed five (5) or more acres of land. In December 2003, this requirement was added to small construction activities. Small construction activities, as defined by the EPA, are those “that result in a land disturbance equal to or greater than 1 acre and less than 5 acres.” Also regulated as small construction activities are those “disturbing less than 1 acre…if they are part of a larger common plan of development or sale with a planned disturbance equal to or greater than one acre and less than five acres.”

Currently, the ADEQ’s GCP requires that the operator forward a copy of the completed NOI to the owner/operator of the MS4 if the facility has the potential to discharge to the MS4. Since city-owned and maintained streets constitute a significant portion of the City of Surprise storm water conveyance system, it is expected that the majority of construction sites will need to submit copies of all required documents to the city.
