GOALS


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.


Supervisors Facility Engineers Maintenance Personnel Department Managers Building Occupants Process Specialists Environmental Committees

LEARNERS


The goal of this course is to provide supervisors with the tools needed to help prevent storm water pollution from the work done in their building or work area’s. It recommends practical, actions that can be carried out by facility management, maintenance personnel and building occupants. The course will help you to integrate storm water pollution prevention activities into your existing organization and identify which of your staff have the necessary skills to carry out those activities.

OVERVIEW


WHAT THIS COURSE DOES NOT DO

The course is not intended to provide in-depth training in the technical aspects of water treatment, product substitution or land use management. These specialties required training beyond the intended scope of this course. Where this expertise is needed, outside assistance should be solicited.


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.


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 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.


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


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.

SOURCE CONTROLS

Source Controls Regulate the Amount and Rate of Runoff.

These Controls Consist Primarily of Infiltration Devices, and Minimizing the Amount of Directly Connected Impervious Areas.

Examples Include: Minimize Impervious Area Filter Strips and Swales Oil Water Separators

Source Controls:


SOURCE CONTROLS

Oil and Water Separators are Designed to Remove Some Contamination.


TREATMENT CONTROLS

Treatment Controls are Designed to Remove Pollutants from the Runoff. Usually Applied to Drainage Areas Greater Than One Acre. Some Examples of Treatment Controls:

Extended Detention Retention or Wet Ponds Wetlands Filters

Treatment Controls:


Remember, You Control Your Facility or Area! Review Procedures With Them Before Starting the Job! Ensure They Are Properly Trained! Determine Their Environmental Compliance Record! Determine Who Is in Charge of Their People! Determine How They Will Affect Your Facility’s Environmental Compliance!

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
