Phase II Storm WaterNPDES MS4Pollution Prevention Plan 2007 Accomplishments
Acronyms to Know • NPDES-National Pollution Discharge Elimination System • SWPPP-Storm Water Pollution Prevention Plan • MS4-Municipal separate storm sewer system owned by cities that have a population of 5,000 or more and with potential to discharge to valuable or polluted waters • BMP-Best Management Practices • MCM-Minimum Control Measures
NPDES MS4 Permit What is a NPDES MS4 Permit? Permitted MS4 cities must implement storm water pollution prevention plans (SWPPPs) or storm water management programs (both using best management practices (BMPs)) that effectively reduce or prevent the discharge of pollutants into receiving waters.
What is involved in the permit? Permitted MS4 cities are required to address the following 6 general tasks called Minimum Control Measures or MCMs. • Public Education and Outreach • Public Participation/Involvement • Illicit Discharge Detection and Elimination • Construction Site Storm Water Runoff Control • Post-Construction Storm Water Management in New Development and Redevelopment • Pollution Prevention/Good Housekeeping
Did you know? • According to the 1996 National Water Quality Inventory, storm water runoff is a leading source of water pollution. Storm water harms surface waters such as rivers, lakes, and streams which in turn cause or contribute to water quality standards being exceeded.
