MS4 Permits - Get Ready for the Next Round

  1. 1. NPDES MS4GET READY FOR THE NEXT ROUND Presented by: Thomas P. Wilson, PE, CFM
  2. 2. AGENDA1. Background / Why This Is Important2. Six Minimum Control Measures (MCM’s)3. New Permit Conditions: a) Chesapeake Bay Pollutant Reduction Plans b) Total Maximum Daily Load (TMDL) Plans c) Impaired Waters4. Barry Newman’s Top Ten FAQ’s
  3. 3. BACKGROUND• The 1987 amendments to the Clean Water Act mandated EPA to develop a tiered implementation strategy for the NPDES Storm Water Program.• Phase I of the program was implemented in 1990 and it regulated Medium and Large Municipal Separate Storm Sewer Systems (MS4s). • Medium MS4: An incorporated place with a population between 100,000 and 250,000. (Allentown and Erie) • Large MS4: An incorporated place with a population greater than 250,000. (Philadelphia and Pittsburgh)
  4. 4. BACKGROUND• Phase II was published as a final rule in December 1999, and it expanded permit requirements to small MS4s in Urbanized Areas (UAs).• This rule required states to have MS4 permits in place by March 10, 2003. PA issued its Small MS4 General Permit (PAG-13) on March 8, 2003, and it expired at midnight on March 9, 2008.• The permit was extended 6 times until it was announced in the September 17, 2011 PA Bulletin that a revised PAG-13 was issued. [41 Pa.B. 5042]
  5. 5. WHAT’S NEXT?• Municipalities must submit a Notice Of Intent (NOI) by September 14, 2012.• The new permit effective date is March 16, 2013.
  6. 6. WHAT MUST BE DONE?• Six Minimum Control Measures: 1. Public Education & Outreach 2. Public Involvement/Participation 3. Illicit Discharge Detection and Elimination (IDDE) 4. Construction Site Storm Water Runoff Control 5. Post-Construction Storm Water Management in New and Re-Development Activities 6. Pollution Prevention and Good Housekeeping for Municipal Operations• New Requirements
  7. 7. MCM #1 Public Education & Outreach1. Develop and Maintain a Public Education and Outreach Program (PEOP).2. Maintain a list of target audiences like schools, residents, businesses, employers, etc.3. Publish at least one educational flyer, newsletter, pamphlet, etc. annually.4. Distribute Storm Water Management educational materials to target audiences using a variety of methods.
  8. 8. MCM #1Public Education & Outreach Examples of outreach materials: Images from the US EPA
  9. 9. MCM #2 Public Involvement/Participation1. Develop a written Public Involvement and Participation Plan. (PIPP)2. Provide adequate public notice and opportunities for input prior to ordinance adoption.3. Regularly solicit public involvement from target audiences. a) Conduct at least one public meeting per year. b) Document and report activities of public participation.
  10. 10. MCM #2Public Involvement/Participation Images from the US EPA
  11. 11. MCM #3Illicit Discharge Detection and Elimination (IDDE) 1. Develop and Implement a written program: a) Must include dry weather field screening of outfalls. 2. Develop and maintain a map, including all outfalls and surface waters: a) Show entire storm sewer system, including roads, inlets, piping, swales, watershed boundaries, etc. Wash water from a commercial car wash discharging down a storm drain is an example of an illicit discharge. Image from the US EPA
  12. 12. MCM #3Illicit Discharge Detection and Elimination (IDDE) 3. Prioritize, conduct, and record outfall screening. a) Must screen outfalls annually. b) If dry weather flow found: i. Check color, turbidity, solids, odor, and adverse impacts in proximity; if positive collect samples. 4. Enact a SWM ordinance from Act 167 (2005 or later), DEP’s model ordinance, or one that satisfies all EPA requirements.
  13. 13. MCM #3Illicit Discharge Detection and Elimination (IDDE) 5. Annually provide educational outreach to stakeholders. 6. Setup a Storm Water reporting mechanism. (phone and/or internet) 7. Respond to and document complaints. Image from the US EPA
  14. 14. MCM #4 Construction Site Storm Water Runoff Control1. Develop and implement a program for permitting, inspecting, and enforcing the installation of E&S controls. Poorly maintained BMPs can result in significant quantities of sediment being discharged to storm drains. Image from the US EPA
  15. 15. MCM #4 Construction Site Storm Water Runoff Control2. Enact, implement, and enforce an ordinance for the installation of E&S controls.3. Develop and implement requirements for controlling waste at construction sites.4. Develop and implement procedures for receipt of public inquiries.
  16. 16. MCM #5 Post-Construction SWM in New and Re-Development Activities1. Develop a written procedure for implementation. a) Refer to PA Storm Water BMP Manual for guidance.2. Require the implementation of BMPs designed to meet pre-development conditions.
  17. 17. MCM #5 Post-Construction SWM in New and Re-Development Activities3. Ensure controls are installed to minimize water quality impacts.4. Enact, implement, and enforce an ordinance. Image from the US EPA
  18. 18. MCM #5 Post-Construction SWM in New and Re-Development Activities5. Develop and implement measures to encourage LID in new and redevelopment.6. Ensure adequate O&M of all PCSM BMPs. Image from the US EPA
  19. 19. MCM #6 Pollution Prevention and GoodHousekeeping for Municipal Operations 1. Identify and document all activities and facilities with potential impact. 2. Develop, implement, and maintain an O&M program for facilities. Image from the US EPA
  20. 20. MCM #6 Pollution Prevention and GoodHousekeeping for Municipal Operations3. Develop and implement an employee training program. Image from the US EPA
  21. 21. New Permit Conditions1. Chesapeake Bay Pollutant Reduction Plan2. Total Maximum Daily Load (TMDL) Plans3. Impaired Water Requirements
  22. 22. New Permit Conditions1. Chesapeake Bay Pollutant Reduction Plan a. Due within 12 months of approval of coverage. b. A plan, including schedule, to implement BMPs to reduce N, P, and sediment. c. Certification by a Professional Engineer (P.E.)
  23. 23. New Permit Conditions2. Total Maximum Daily Load (TMDL) Plan a. If the MS4 discharges to water with an approved waste load allocation (WLA) in a TMDL, the applicant must implement an MS4 TMDL Plan. b. This plan must be designed to achieve pollutant reduction in the TMDL and include: i. TMDL Strategy: Narrative of Pollution Control Measures (PCMs) and BMPs that will be implemented, analyzed, and reported on to show measurable progress. ii. TMDL Design Details. iii. Strategy must be submitted with the NOI and approved by DEP. iv. Certification by a Professional Engineer (P.E.)
  24. 24. New Permit Conditions3. Impaired Waters a. If discharge is to an Impaired Water, but not an approved TMDL, permitees must ensure “New Discharges” do not contribute to exceeding water quality standards.
