National Stormwater Discharge Program
• Phased approach by EPA– Phase I – 1990 – large cities– Phase II – 1999 – smaller municipalities

National Stormwater Discharge Program in RI is often called:
- Phase II program
or- Rhode Island Pollutant Discharge Elimination System
(RIPDES) Program
.or - Storm Water Discharge from
Small Municipal Separate Storm Sewer Systems (MS4s) Program

General Permit
• Authorized to discharge storm water if have submitted and are implementing a Storm Water Management Program Plan (SWMPP)
![Page 10: 1 Module 1: Refresh Your Perspective on the Storm Drain System Stormwater System Maintenance: A 4-Part Workshop Series](https://reader035.vdocuments.us/reader035/viewer/2022062500/5697bfd61a28abf838cae085/html5/thumbnails/10.jpg)

MS4-specific plan
• What MS4 is going to do– Procedures developed– Site specific plans
• Where MS4 will do it– Regulated areas– Specific
locations/facilities– Specific activities

Pollution Prevention & Good Housekeeping Requirement
• Develop and implement a program to prevent and reduce storm water pollution from operations and maintenance (O&M) activities that have the potential to introduce pollutants to storm water runoff

O&M Program Goals
Identify & describe Structural BMPs
Inspect, clean & repair Structural BMPs
Inspect & clean Catch Basins
Stabilize Road Shoulders & Ditches
Check Outfalls for scouring, sedimentation
Sweep all roads annually
Reduce Floatables Waste Disposal

For each module, we will
• Review the goals as written in the General Permit
• Clarify or expand as needed
• Review what we are doing now
• Review how we report our activities
• Look for ways to improve our effectiveness and/or efficiency

Storm Water System
• Traditional Purpose:– Convey excess water
to a safe location
• Additional Purpose:– Remove/treat
pollutants before they reach a water body
