Stormwater runoff and snow melt can pick up chemicals, bacteria, sediment, and debris from urban areas,
construction sites, and industrial facilities. Runoff that enters a storm sewer or ditch does not go to
a lagoon or treatment plant. Instead, runoff flows directly to rivers, lakes, and streams without any
Stormwater permits provide a level of treatment through planning and management that minimizes pollution
in runoff from urban areas, construction sites, and industrial facilities.
There are no fees for stormwater permits. For more information please email email@example.com.
Construction Permits: The construction general permit applies to construction projects that disturb one or
more acres including smaller projects within or part of a large development.

Coverage under the permit is required for oil and gas projects if runoff from the project
can carry eroded material to a water of the state. Coverage is not
required for oil and gas projects if runoff will not carry eroded material to
a water of the state.
Industrial permits are required if a facility falls under a specific primary Standard
Industrial Classification (SIC) Code. Examples of industrial activity under these codes include, but are not
limited to Asphalt/Concrete plants, Landfills, Manufacturing, and Transportation. Find your
facility's SIC code on the OSHA Website. See the
EPA Website to find out if your facility
requires a permit.
