Introduction

 Review Elements of the Municipal Separated Storm Sewer

System(MS4) Permit Application

 http://www.michigan.gov/documents/deq/wrd-stormwater-

MS4-Application_402860_7.pdf

 Permit Application Elements

 Storm Water Management Program the eight elements

 Eighty plus procedures required

 Illicit Discharge Elimination Program

 Case Histories  How IPP staff can be the eyes and ears

 Accomplishmnets

Permit Application Elements

 Define the regulated urbanized areas as defined by the

2000 Census

Permit Application Elements

 Identify discharges to waters of the State

 Identify discharge points

 Identify the point where your system discharges to another

jurisdiction

 Agreements between

jurisdictions on follow up is allowable

 Note- open county drains

are considered Waters of the State

Permit Application Elements

 List nested jurisdictions in the application

 E.g. school districts  Community/ies under a county permit

 Provide name and general description of nested

jurisdictions

• Response to violation of permitees ordinances
• Contain the ordinance/s
• Method for tracking non-compliance
• Date/location
• Nature of the violation
• Enforcement response used
• Schedule for compliance
• Date violation was resolved

Stormwater Management Program

Public Participation Plan

• If it a collaborative effort with watershed or regional

partners identify, the collaborative activities

• Procedures on how the public participates in the

development of the Stormwater Management Plan

• How is the Plan made available for public review/comment?
• How the public is invited to participate in implementation

and review?

Stormwater Management Program

3.

Public Education Program (PEP)



Provide procedure to assess high priority community issues and target the issues to reduce pollutants in stormwater



Identify /prioritize PEP topics based on assessment of community high priority issues.



Eleven PEP topics in the permit application



For each topic provide



Target audience



Key message



Delivery mechanism and frequency

Stormwater Management Program

3.

Public Education Program (PEP)

• Topics include:
• Promote public stewardship of watersheds
• Educate the public on illicit discharges
• Education on importance of green infrastructure
• Education on the proper maintenance of septic systems
• Promote methods for proper riparian lands to protect water

quality

• Identify /educate commercial, industrial, institutional

entities that may contribute pollutants to stormwater

• Provide a procedure for evaluating effectiveness of the PEP
• Assess changes in public awareness

Stormwater Management Program

• 4. Construction Stormwater Runoff Program
• Is the permittee a Part 91 agency (Soil Erosion)?
• If not list the agency it relies on for Part 91 agency
• Procedure for notifying the Part 91 agency when pollutant from a

construction site enters MS4.

• Procedure to notify MDEQ when pollutant from a construction

site enters MS4.

• Procedure to notify Part 91 agency of construction activity

greater than one acre.

Stormwater Management Program

• 5. Post Construction Stormwater Runoff Program
• Ordinance for post construction runoff
• Water quality performance standard
• Treat first inch of runoff from entire site
• Treat runoff from 90% of all runoff producing storms
• Source of rainfall data
• Channel Protection Performance Standard
• Site runoff does not exceed pre development rate and

volume up to 2 year 24 hour storm

Stormwater Management Program

• 5. Post Construction Stormwater Runoff Program
• Site specific requirements (new and redevelopment)
• Infiltration BMP should not exaberate current groundwater

contamination issues.

• Do BMPs consider potential pollutants from “hotspots”
• (E.g. gas stations, auto recyclers, scrap yards, etc)
• Off-Site Mitigation/Payment in Lieu Programs
• Is off-site mitigation allowed for redevelopment?
• Does ordinance allow Payment in Lieu?
• Fee paid to permitee for stormwater management project
• Same jurisdiction, watershed, sewershed

Stormwater Management Program

• 6. Pollution Prevention and Good Housekeeping



Municipal Facility and Structural Stormwater Control Inventory



Updated inventory of municipal facilities and stormwater structures



Municipal facilities



Police/Fire stations, vehicle yards, public parking lots, animal control building



Structural storm water controls e.g. rain gardens, catch basins, constructed wetlands, pump stations



Up-to-date maps with locations for items above



Procedure for updating the inventory

Stormwater Management Program

• 6. Pollution Prevention and Good Housekeeping



Maintenance Activities for Structural Stormwater Controls



Procedure for prioritizing routine inspection, maintenance and cleaning of catch basins



Revision procedure for updating priority areas.

Stormwater Management Program

• 6. Pollution Prevention and Good Housekeeping



E.g. streets, parking lots 

Identify street sweeping methods



Seasonal issues e.g. leaf pickup 

Describe dewatering and disposal of waste material



Management of vegetated properties



Certified pest control applicator 

Employee training



Employee training program for staff that perform pollution prevention and good house keeping

Stormwater Management Program

• 6. Pollution Prevention and Good Housekeeping



Contractor requirements



Comply with pollution prevention and good housekeeping practices

• 7. Total Maximum Daily Load (TMDL) Implementation Plan



A TMDL Implementation Plan will have a waste load allocation to the municipality



Describe current/future Best Management Practices (BMP)that make progress towards meeting waste load allocation in TMDL plan



Monitoring plan to assess effectiveness of BMP to reach load reduction requirement in the TMDL plan.

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)
• Definitions
• Illicit Connection- physical connection

to a MS4 that convey non-stormwater discharge or not authorized by local authority

• Illicit Discharge-any discharge or seep

that is not stormwater or uncontaminated ground water

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)
• Examples of Illicit Discharges

Grey Water Discharge

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)



Up-to date storm sewer system map



Identify location of outfalls



Identify points of discharge



Identify water of the State that receive the discharge



Indicate where the maps can be found

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)
• Procedure for prioritize areas with potential of illicit

discharges

• E.g. Areas with:
• History of illicit discharge
• Onsite Sewage Disposal Systems
• Older infrastructure
• Poor dry weather water quality
• Provide geographical location of priority areas

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)
• Procedure for prioritizing areas with potential for

illicit discharges

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)
• Procedure for field observations of outfalls

• f the state from storm system
• Polluting material defined by Part 5 rules.
• Response to illicit discharge
• Corrective action
• Compliance schedule

Stormwater Management Program

• 8. Illicit Discharge Elimination Program (IDEP)
• IDEP Training of staff

CASE HISTORY – RESTORING RECREATIONAL USE ALONG THE MIDDLE BRANCH

 1997 city planning

 TV’ed sewer – no taps (completed)  Sent letters to residents (not completed)  Dye tested homes (not completed)

 1997 County actions

 Intermittent monitoring  Does problem still exist?

 Evidence of problem disappeared  Continued monitoring

CASE HISTORY – RESTORING RECREATIONAL USE ALONG THE MIDDLE BRANCH

 Memorial Day 1998 – problem back!

 Sent letters out  Dye testing  Educational material sent to homeowners

 Late 1998 – evidence of problem - disappeared  1999 - Clean  2000 - Clean

CASE HISTORY – RESTORING RECREATIONAL USE ALONG THE MIDDLE BRANCH

 Probable cause

 Recreational vehicle/boat dumping sanitary waste  Pet waste

CASE HISTORY – RESTORING RECREATIONAL USE ALONG THE MIDDLE BRANCH WHAT DID WE LEARN?

 Persistence pays  Observable presence in the area had an affect  Public education worked

IPP Staff “Eyes and Ears”

 Be an alert observer  Report suspicious discharges
