A 5-Part Workshop Series

Training Modules

1. Why Stormwater Matters 2. What is a SWPPP?

3. Spill Prevention & Response

4. Materials Management

5. Good Housekeeping

What is a SWPPP?

• Relation to Clean Water Act & RIPDES

• Contents of site-specific SWPPP

• Exercise: What do we do outdoors?

Storm Water Pollution Prevention Plan

• Site (Facility) Specific

• Facility Staff all have a role in implementation

National Stormwater Discharge Program

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

“public bodies”

GENERAL PERMITSunder

Rhode Island Pollutant Discharge Elimination System

• Storm Water Discharge Associated with Industrial Activity (Multi-Sector)

• Storm Water Discharge fromSmall Municipal Separate Storm Sewer Systems (MS4)

General Permit Requirement

• Implement a site-specific Storm Water Pollution Prevention Plan (SWPPP) developed for each facility with “industrial” activity

SWPPP requirements

• Facility Associated with a MS4– Section IV.B.6.b.5. of

MS4 General Permit

(Good Housekeeping)

• Multi-Sector– Section IV of Multi-

Sector General Permit

SWPPP Contents

• Site-specific

• Describe BMPs (Best Management Practices)

• Structural and non-structural controls for reducing or eliminating discharge of pollutants from operations and facilities

• Storm water-related: Outdoors

SWPPP must describeCOORDINATOR

• Individual responsible for coordinating and implementing practices, inspections, evaluations and updates

SWPPP must describe FACILITY

activitieso Location of drainage

system, including BMPs

o Location of onflows of runoff from adjacent properties

o Receiving waters

SWPPP must describe MATERIALS & ACTIVITIES

o Assessment of potential of each to contribute pollutants to storm water discharges

SWPPP must describe PRACTICES TO CONTROL POLLUTANTS

o Good housekeeping practices

o Preventive maintenance

o Existing/planned BMPs for activities

SWPPP must describe PROCEDURES FOR

EVALUATION OF COMPLIANCE

o Visual monitoringo Annual site

inspectionso Record keeping &

reporting

SWPPP must be AMENDED
