As of March 10, 2003, construction activity that disturbs one or more acre of land, including that conducted by a municipality, needs the Construction General Permit (CGP).
What EPA considers "construction activity": clearing, grading, excavation and other land disturbance activities related to projects such as landscaping, demolition, and building homes, office buildings, factories, roads, etc.
If your own work site creates less than one acre of disturbance, but is part of a larger "common plan of development or sale" totaling that many acres of disturbance, you need a permit. It is important to note that the threshold is for total disturbance. The areas of disturbance do not need to be contiguous to be included in the calculation of total disturbance.
