GOALS
Storm Water P2 5 / 61 © Copyright Training 4 Today 2001 Published by EnviroWin Software LLC
BACKGROUND
Storm water discharges are often the #1 source of ocean, bay, lake, and river pollution in the U.S.
It is estimated that storm water contributes as much as 80 percent of the total water pollution in the U.S.
One quart of oil can contaminate 250,000 gallons of water. One pint of motor oil can produce an oil slick one acre in size. This training helps improve environmental compliance with
the Clean Waster Act.

WHAT IS STORM WATER?
STORM WATER:
• Rain, Snow or Ice Melt• Water that DOES NOT SEEP Into the
Ground but is Channeled by Storm Sewers.
• Final Destination of Storm Water is Streams, Rivers, Lakes or the Ocean.
Storm Water P2 10 / 61 © Copyright Training 4 Today 2001 Published by EnviroWin Software LLC
WHAT CAUSES STORM WATER POLLUTION?
STORM WATER POLLUTION:
• Rain, Snow or Ice Melt Carries Pollution.• Oil, Antifreeze, Detergents, Pesticides, and Other
Pollutants.• Water Flows into Storm Drains. • Storm Drains Channel Water Directly into Streams,
Rivers, Lakes or the Ocean.
Storm Water P2 11 / 61 © Copyright Training 4 Today 2001 Published by EnviroWin Software LLC
STORM DRAINS
STORM DRAINS:
• Found Near Businesses, Homes and Street Corners.
• Called Storms Sewers, BUT Are Different from Sanitary Sewer System.
• Water Flowing in Storm Sewers is Untreated.

THE CLEAN WATER ACT
CLEAN WATER ACTSection 402(p) - Establishes Framework for Regulating Storm Water Discharges Under National Pollutant Discharge Elimination System (NPDES) Program.
FEDERAL REGULATIONS:40 CFR Parts 122-125 - NPDES regulations 40 CFR Part 122.26 - Storm Water Discharges (subject to NPDES program) 40 CFR Subchapter N - National effluent limitations guidelines.
Storm Water P2 13 / 61 © Copyright Training 4 Today 2001 Published by EnviroWin Software LLC
NPDES PROGRAM
The following eleven categories are defined in federal regulations 40 CFR 122.26(b)(14)(i)-(xi) as sources of "storm water discharge associated with industrial activity:“ • Facilities with Effluent Limitations • Manufacturing • Mineral, Metal, Oil and Gas • Hazardous Waste Treatment, Storage, or Disposal Facilities • Landfills • Recycling Facilities • Steam Electric Plants • Transportation Facilities • Treatment Works • Construction Activity • Light Industry
Storm Water P2 14 / 61 © Copyright Training 4 Today 2001 Published by EnviroWin Software LLC
NPDES PROGRAM
• All Municipalities with population over 100,000 Require a NPDES Permit.
• Even if Your Business Does Not Require Its Own NPDES Permit, If the Business is in a Municipality Requiring a Permit, the Business is Required to be in Compliance with the Municipality’s NPDES Permit.
MUNICIPAL NPDES PERMITS

THE IMPORTANCE OF A CLEAN ENVIRONMENT
“I would ask all of us to remember that protecting our environment is about protecting where we live and how we live. Let us join together to protect our health, our economy, and our communities -- so all of us and our children and our grandchildren can enjoy a healthy and a prosperous life.”
Carol Browner Former EPA Administrator
