1 the basics of illicit discharges
1) The Basics of Illicit Discharges
  • Important terminology and key concepts
  • The importance of illicit discharges in urban water quality
  • Regulatory background for illicit discharges
  • Experience gained in Phase I

WAY MS4 IDDE

important terminology and key concepts
Important Terminology and Key Concepts

Illicit discharges are defined as:

  • A storm drain that has measurable flow during dry weather containing pollutants and/or pathogens.
  • Each illicit discharge has a unique frequency, composition and mode of entry in the storm drain system.
  • Illicit discharges are frequently caused when the sewage disposal system interacts with the storm drain system.
  • Illicit discharges of other pollutants are produced from specific source areas and operations known as “generating sites.”

WAY MS4 IDDE

2 components of an effective idde program
2) Components of an Effective IDDE Program
  • Go after continuous sewage discharges first
  • Put together an interdisciplinary and interdepartmental IDDE team
  • Educate everybody about illicit discharges
  • Understand your infrastructure
  • Walk all of your streams in the first permit cycle
  • Use GPS to create your outfall map
  • Understand your discharges before developing a monitoring plan
  • Consider establishing an ambient (in-stream) chemical and/or biological monitoring program

9) Utilize a simple outfall tracking system to organize all your

IDDE data

  • Outsource some IDDE functions to local watershed groups
  • Utilize a hotline as an education and detection tool
  • Cross-train all local inspectors to recognize discharges and report them for enforcement
  • Target your precious storm water education dollars
  • Stress public health and safety benefits of sewage-free streams
  • Calibrate your program resources to the magnitude of the illicit discharge problem
  • Think of discharge prevention as a tool of watershed restoration

3 searching for illicit discharge problems in the field
3) Searching for Illicit Discharge Problems in the Field
  • Overview of Searching for

Illicit Discharge Problems in the Field

    • The Outfall Reconnaissance Inventory (ORI)
    • Interpreting ORI Data
    • Design and Implementation of an Indicator Monitoring Strategy
    • Field and Lab Safety Considerations

WAY MS4 IDDE

overview of searching for illicit discharge problems in the field
Overview of Searching for Illicit Discharge Problems in the Field
  • Purpose: Rapid field screening of outfalls in priority

subwatersheds followed by indicator monitoring at

suspect outfalls to characterize flow types and trace

sources.

  • Method(s): The primary field screening tool is the Outfall

Reconnaissance Inventory (ORI) and a map.

  • Desired Product or Outcome(s):
    • An updated map of the locations of all outfalls within the MS4
    • Incorporation ORI data into the outfall inventory/tracking system
    • Design and implementation of indicator monitoring strategy to test

suspect outfalls

    • Creation of local pollution “fingerprint” library for discharge types
    • Evaluate significance and distribution of IDPs in the community

WAY MS4 IDDE

field and lab safety considerations
Field and Lab Safety Considerations
  • Program managers should take

into account and fully plan for all

necessary field and laboratory

safety precautions.

  • Most communities already have

well established standard

operating procedures they follow

when conducting field and lab

work, and these typically provide

an excellent starting point for IDDE

programs.

WAY MS4 IDDE

overview of program evaluation
Overview of Program Evaluation
  • Purpose:
    • This last program component addresses the ongoing management of the IDDE program and reviews progress made in meeting the measurable program goals established earlier in the permit cycle.
  • Method(s):
    • The primary method is frequent maintenance and analysis of the IDDE tracking system developed as part of the program.
  • Desired Product or Outcome(s):
    • Updated tracking database and annual report with summary of progress to date, findings, recommendations for program revisions, and work plan (including milestones and goals) for the upcoming year.

idde program tracking
IDDE Program Tracking
  • Geospatial coordinates of each outfall location
  • The subwatershed and watershed address
  • Any supporting information about contributing land use
  • Diameter and physical characteristics of the outfall
  • Outfall Reconnaissance Inventory (ORI) data
  • Any accompanying digital photos
  • Any follow-up monitoring at outfall or further up the pipe
  • Any hotline complaints logged and local response
  • Status and disposition of any enforcement actions
  • Maintenance and inspection data

evaluate the program
Evaluate the Program
  • Updated mapping to reflect outfalls located during ORI
  • Surveyed stream reaches with locations of obvious, suspect, and potential discharges, and locations of dumping sites
  • Indicator sampling results for specific streams, outfalls and storm drains
  • Frequency of hotline use and associated number of “hits” or confirmed illicit discharges
  • Costs for each of the eight program components (e.g., office, field, lab, education, enforcement, etc.)
  • Number of discharges corrected
  • Status and disposition of enforcement actions

Desktop Analysis to Support the ORI
  • Survey reaches should be established above the confluence of streams and between road crossings that serve as a convenient access point.
  • Survey reaches should be defined at the transition between major changes in land use in the stream corridor (e.g. forested land to commercial area).
  • Survey reaches should generally be limited to a quarter mile or less in length. Survey reaches in lightly developed subwatersheds can be longer than those in more developed subwatersheds, particularly if uniform stream corridor conditions are expected throughout the survey reach.
  • Access through private or public property should be considered when delineating survey reaches as permission may be required.
