NPDES Construction Stormwater Program

Chapter 102 Erosion Control requires a General NPDES Permit or an Individual NPDES Permit when a person proposes to disturb one or more acres during the duration of an earth disturbance activity. This includes earth disturbance on any portion, part or during any stage of the activity, or earth disturbance during any stage of a larger common plan or development or sale.

An Individual NPDES Permit for Stormwater Discharges Associated with Construction Activities is required for sites in special protection watersheds and sites that are unable to meet the nine eligibility requirements listed in the General PAG-02 permit. A PAG-01 General NPDES Permit for Stormwater Discharges Associated with Small Construction Activities is applicable for sites disturbing under five acres and meeting all PAG-01 specifications.
