Is a Stormwater Permit Required for Your Construction Project?
The term "stormwater" refers to any runoff after rain or snow from a barren piece of land, an area with vegetation, or constructed areas such as paved streets and rooftops. Stormwater discharges can contain pollutants in large enough quantities to contaminate a water supply. If a construction project will disturb one or more acres, you may be required to obtain a stormwater permit under the federal Clean Water Act. Even if a project will disturb less than one acre, you may need a stormwater permit if it is part of a larger development plan.
