National Stormwater Discharge Program

• Phased approach by EPA– Phase I – 1990 – large cities– Phase II – 1999 – smaller municipalities

8

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

9

General Permit

• Authorized to discharge storm water if have submitted and are implementing a Storm Water Management Program Plan (SWMPP)

10

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

13

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

• Traditional Purpose:– Convey excess water

to a safe location

• Additional Purpose:– Remove/treat

pollutants before they reach a water body
