  2. Agenda Welcome and Introduction 12:45am – 12:50pm Scottie Ferguson, Pickens County EPA IDDE Requirements Overview 12:50 – 1:15pm Trevor Gauron, EPA Representative Ft.

  3. Storm Drainage Overflow

  4. What is an Illicit Discharge? • A discharge to an MS4 that is not composed entirely of storm water except permitted discharges and fire fighting related discharges 40 CFR 122.26(b)(2) • Unique frequency, composition & mode of entry • Interaction of the sewage disposal system & the storm drain system - Produced from “generating sites”

  5. EPA Illicit Discharge Detection and Elimination Train-the-Trainers workshop • Cosponsored by EPA and Center for Watershed Protection • Class designed to train-the-trainers • Attendees to offer assistance to answer questions and help communities develop IDDE programs • EPA has not offered much help regarding IDDE requirements • Phase II requirements are vague • Letter sent to NPDES communities endorsing IDDE manual to be used as a guide to develop programs Scan cover of workshop and paste here.

  6. NPDES Program Requirements (Source: 64 FR 68722 – December 8, 1999) • Approximately 5000 Phase II communities • Only 20% have an IDDE program • In 2008 EPA will start the auditing process • Look for an MS4 Auditing Guide coming soon Phase II Requirements: • Storm sewer system map • Regulatory mechanism (e.g. ordinance) to prevent illicit discharges • Must Prohibit, Investigate, Eliminate, and Enforce • Plan to detect & address non-storm water discharges • Education • Measurable goals

  7. IDDE Guidance Manual • Audit Existing Resources & Programs • Establish Responsibility, Authority & Tracking • Complete a Desktop Assessment of Illicit Discharge Potential • Develop Program Goals & Implementation Strategies • Search for Illicit Discharge Problems in the Field • Isolate & Fix Individual Discharges • Prevent Illicit Discharges • Evaluate the Program • Download at www.cwp.org or http://cfpub1.epa.gov/npdes/home.cfm?program_id=6

  8. Infrastructure profile Legal authority Available mapping Field staff Access to lab services Education & outreach resources Discharge removal capability Program budget & financing Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Audit Elements: Potential Infrastructure Profile Questions: How many miles of streams and storm drains exist in the MS4? What is the area served by storm drains, sewers, and septics? What is the general age and condition of the infrastructure?

  9. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Illicit Discharge Ordinances • Prohibit illicit discharges & illegal connections • Provide for access & inspection • Require & enforce elimination • Address unique conditions or requirements

  10. Past Discharge Complaints Poor Dry Weather Water Quality Density of Generating Sites Density of Industrial NPDES Permits Stormwater Outfall Density Age of Subwatershed Development Former Combined Sewers Older Industrial Operations Aging or Failing Sewers Density of Older Septic Systems Past Sewer Conversions Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Prioritization Factors to Consider • Communities should consider a number of factors when prioritizing watersheds for inventory, dry weather screening, and illicit tracking: Select the factors that apply most to your community

  11. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Key: Low IDP risk Medium IDP risk High IDP risk Communities with… Severe Illicit Discharge Problems Minimal Illicit Discharge Problems Clustered Illicit Discharge Problems

  12. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Measurable Goals • Measurable Goals for an IDDE Program • Table 17 in IDDE manual

  13. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Search for Illicit Discharge Problems in the Field • Purpose: • Conduct rapid field screening to identify & track suspected outfalls & stream segments • Conduct investigatory sampling & analysis to establish flow types & likely sources • Desired Outcome: • Locations & characterizations of all outfalls • Strategy for future chemical analysis

  14. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Finding and Fixing • Move up the pipe using flowchart methodology • Use smoke, dye, or video testing once narrowed • Use enforcement or repair

  15. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Techniques to Locate the Discharge Source: www.darrscleaning.com Source: NEIWPPC,2003 Source: www.darrscleaning.com Source: www.darrscleaning.com Source: www.darrscleaning.com

  16. Leads to early detection & correction Encourages active public stewardship Can “piggyback” on other call response needs Identifies suspected facilities for further investigation & education Increases municipal accountability Good tool to pick up intermittent and transitory discharges Time & money to provide 24/7 service Marketing the hotline number Establishing inter- & intra-departmental response process Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Discharge Complaint Hotline

  17. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Prevent Illicit Discharges • Education programs that target the most common intermittent and transitory discharges • Three sectors: neighborhoods, generating sites, and municipal housekeeping www.epa.gov/nps/toolbox

  18. Audit Authority Desktop Assessment Goals & Strategies Search for Discharges Isolate & Fix Discharges Prevent Discharges Tracking & Evaluation Program Tracking and Evaluation • A summary of program statistics: • 302 total illicits found, 186 remediated, 116 on-going

  19. What is EPA looking for? From IDDE Webcast on 9/12/06: EPA is looking for is a logical plan based on investigations into the uniqueness of your MS4 or community.

  20. IDDE Resources The following IDDE resources are readily available to MS4s: • Center for Watershed Protection (CWP) IDDE Manual • Free download at: • http://cfpub1.epa.gov/npdes/home.cfm?program_id=6 • New England IDDE Municipal Manual • Free download at: • http://www.neiwpcc.org/PDF_Docs/iddmanual.pdf • IDDE Workshop Presentations • Available on SMC website: • http://www.co.lake.il.us/smc/regulatory/npdes/IDDEwrkshp.asp 1. Design of a Basic IDDE Program- Includes specific steps and tools based on EPA’s recommended eight components of an IDDE Program described in the CWP IDDE manual. 2. Your Municipal IDDE Program- Ideas for Years 3-5 3. IDDE Case Studies
