The National Pollution Discharge Elimination System (NPDES) permit program reduces water pollution by regulating point sources that discharge to Waters of the United States.  NPDES was created in 1972 by the Clean Water Act and is administered by the United States Environmental Protection Agency (US EPA).  The US EPA, in turn, authorizes state governments to fulfill the permitting, administrative and enforcement aspects of the NPDES program.  Storm Water Pollution Prevention Plans (SWPPPs, discussed below) are part of the storm water permits administered under NPDES.

 

Indiana Rule 5 Storm Water Pollution Prevention Plan 

An Indiana Rule 5 Storm Water Pollution Prevention Plan (Rule 5 SWPPP) is a site-specific plan that helps protect waters of the state from pollutants in storm water runoff associated with construction activities. Rule 5 SWPPPs contain information about project site hydrology, planned construction activities, potential sources and measures that will be taken to control erosion, pollution and runoff. 

Having a Rule 5 SWPPP in place is a requirement of the NPDES general permit as administered by Indiana.  Most construction activities that disturb more than 1 acre of land (and some that disturb less than 1 acre) are required by the Indiana Department of Environmental Management (IDEM) to have a Rule 5 general permit (which necessitates a Rule 5 SWPPP).

Indiana Rule 6 Storm Water Pollution Prevention Plan 

An Indiana Rule 6 Storm Water Pollution Prevention Plan (Rule 6 SWPPP) is a site-specific plan that shows where runoff is discharged from an industrial property and identifies possible pollutants it could be carrying. Rule 6 SWPPPs contain information about property hydrology and land use, current or planned industrial activities, potential pollutant sources and measures that are taken to monitor and control pollution in property runoff.  

Rule 6 SWPPPs are part of the NPDES general permit as administered by Indiana.  A facility's applicability to Rule 6 is determined by the facility's Standard Industrial Classification (SIC) codes, the presence of industrial activities exposed to storm water and the existence of one or more outfalls on the facility's property.  Facility operators (not property owners) are responsible for determining applicability and complying with Rule 6 requirements.

Illinois Storm Water Pollution Prevention Plan 

An Illinois Storm Water Pollution Prevention Plan (IL SWPPP) is a site-specific plan that helps protect waters of the state from pollutants associated with construction or industrial activities.  IL SWPPPs contain information about property hydrology and land use, current or planned construction activities or industrial activities, potential pollutant sources and measures that are taken to monitor and control erosion and pollution in property runoff.  

IL SWPPPs are a requirement of the NPDES general permit as administered by Illinois.  A facility's applicability to NPDES is determined by the facility's Standard Industrial Classification (SIC) codes, the current or planned presence of construction or industrial activities exposed to storm water, and the existence of one or more outfalls on the facility's property. Facility operators (not property owners) are responsible for determining applicability and complying with NPDES requirements.
