2. Stormwater System Maintenance The Dos and Don’ts of Street Sweeping, Catch Basin Cleaning & Structural Control Inspections

3. Presentation Topics • Catch Basin Cleaning: • Prioritizing Areas/Scheduling • Maintenance, Disposal & Documentation • Street Sweeping • Reasons for Sweeping; Prioritizing Areas • Disposal & Documentation • Detention Basins • Overall maintenance evaluation • Additional Resources

4. NPDES Phase II Requirements Know what you own &/or operate Map and/or list Maintenance Procedures Maintenance Schedules Maintenance Waste Disposal

5. For all Stormwater Structural Control Maintenance…. • Roads; Parks; Admin Buildings; Public Works; Parks; Golf Course Maintenance; Schools; Bus Yard/Transportation Facilities/Other • Storm sewers / catch basins • Detention Basins • Other stormwater BMPs • Swirl Concentrators • Catch Basin Inserts • Swales • Pervious Pavement • Maintenance Activities • Street Sweeping • Catch Basin Cleaning • Detention Basins

6. For all Stormwater Structural Control Maintenance…. • Waste Characterization… • Identify what you dispose/discard from your facility & maintenance practices • Examples from Municipalities; Counties & School Districts • Catch Basin Cleanings / Storm Sewer Cleanout Residue • Sanitary Sewer Cleanout Residue • Street Sweepings • Used Oil; Filters; Batteries • Fluorescent Light Bulbs • Computers • Other Vehicle Maintenance Wastes

7. For all Stormwater Structural Control Maintenance…. • Waste Characterization… • Document • MDEQ Waste Characterization Guidance • Knowledge &/or Analytical Testing • Disposal Facility – Waste Profile Sheet • Keep for 3 years • Site ID issued by MDEQ (Form EQP5150) • Catch Basin Cleaning/Street Sweeping

8. Waste Characterization Summary* • Storm Sewer Cleanout Residue (i.e. catch basin cleanings) • Liquid Industrial Waste [Part 121 of Act 451] • Street Sweepings • Solid Waste [Part 115 Rule 130] • Liquid Industrial Waste (if free liquids) • Unless inspection (odor, color, stains, etc.) or knowledge (past spill) determines impact Material not Designated Waste* • Ditch Cleanings • Excavated Dirt from Watermain Breaks • Follow-up from March 2010 Training • Not a waste if only potable water contained in dirt *Awaiting MDEQ Confirmation/Requesting Clarification

9. For all Stormwater Structural Control Maintenance…. • Written Procedures… • Prioritizing Areas for Maintenance • Maintenance Schedules • Contractor vs. In-House Maintenance • Forms/Tracking: Inspection & Cleaning • Transport & disposal requirements • On-site (Public Works/Road Commission/School District Bus Yard) • Outside Contractor • Document…document…document EVERYTHING! • KEEP ALL YOUR DOCUMENTATION!

10. Catch Basin Cleaning • Municipality vs. Contractor (Site ID Form EQP5150) • Prioritizing Areas/ Collaborating Across Jurisdictions • Inspections/Cleaning • Transport & Disposal • Contractor Manages • Municipality Transports to Disposal Facility (WWTP or Landfill: Contact for Requirements)

11. Catch Basin Cleaning • Prioritize • County/community wide vs. municipal-owned properties • Standard rotating schedule • Roads: every 5 years • Properties: monthly; semi-annually; annually • Maintenance yards more frequently than employee /public parking lots • Areas w/ BMPs vs No BMPs • Areas Draining directly to “Impaired” Waters • Areas receiving high sediment load Photo Courtesy of ECT

12. Catch Basin Cleaning • Inspections • Prior to cleaning • Criteria for Cleaning • With Sump: > ½ Full • No Sump: Clean All Dirt • Odor, Stains, Sheen, Color Bloomfield Township *Once approximately 50% full, runoff into catch basins tends to flush-out material (MPCA, 2000)

13. Vactoring Catch Basins • Consolidated Manifest • Generator ID • Transporter ID • Designated Facility ID • Dewatering Facility • WWTP • Landfill • Trip Log • Date, locations, material & quantity, designated facility • Map Canton Township

14. Once we have vactored…then what? • Transport to Dewatering/ Decanting Location • Must be manifested • Generator; Transporter; Designated Facility • Dewatering Facility • Enclosed • Drains to Sanitary (w/ approval) • No trackout • Solids to landfill City of Saline

15. Dewatering Facilities Wayne County

16. Manifesting Requirements • Site ID (EQP 5150) • Owner Cleaning • Municipality • County • School District • Generator = Owner • Transporter = Owner • Designated Facility = Liquid Industrial Waste Facility • Owner if Dewatering @ Site • Disposal Facility if WWTP or Landfill • Contractor Cleaning • Generator = Contractor • Transporter = Contractor • Act 138 Permit & Registration • Insurance Requirements • Designated Facility = Liquid Industrial Waste Facility • WWTP • Landfill • See MDEQ Waste Data System to locate transporters & designated facilities. • See Consolidated Manifest & Operational Memorandum 121-3 & 121-4

17. Request for Bid Reference to applicable regulations Requirement to maintain traffic flow Cleaning assigned catch basins Notify DPW of catch basins needing repair Price per catch basin/lineal foot storm sewer Documentation Procedures City inspects/marks prior to contractor cleaning Inspection report Decant log Slurry solids Contractor using lined rolloff box Transport to designated facility daily Approximately $42k annually; 800 catch basins Case Study: City of Farmington Hills

20. Street Sweeping • Prioritizing & Scheduling • Properties (quarterly/monthly) • Public & Employee Parking Lots • Maintenance Yards • Bus Yards • Roads (2x per year or more) • Primary; Secondary; Local • Areas w/ BMPs vs No BMPs • Impaired Streams • High Sediment Load

22. Sweepings Dewatering & Disposal • Storage for dewatering • Enclosed • Drains to Sanitary (w/ approval) • No trackout • Solids to landfill City of Saline

23. Case Study: Canton Township • Mechanical and Vacuum Sweepers (leased then purchased both) • Prioritizing/Scheduling • Construction Sites • DDA (Ford Road) • County (Main) Roads (monthly) • Municipal Parking Lots (bi-monthly) • Residential on request • $110/curb mile (1,000 mi/year) • Canton Waste Recycling provides 10 yard roll-off box at DPW • Approx 200 yards annually • CWR transports to landfill • Periodic analytical testing required by landfill • Waste profile sheet retained as waste characterization

24. Detention Basins • Properties • Municipal • Parks • Maintenance Yards • Schools & Maintenance Facilities • Maintenance & Responsibility • Storm sewer system/inlet(s)/outlet • Sediment accumulation • Erosion • Trash/Debris

25. Inspection Basics: Know your Design • Review Engineering and Landscape Plans. • As-Builts/Final Measures are Critical if Available • Location of inlets/outlet • Permanent water or not? • Emergency overflow location www.land2plan.com/Stormwater.htm

26. Inspection Basics • Structural Components • Inlets/Outlet Pipe • Embankment • Clogging • Vegetation – • Presence of Erosion • Plant Diversity • Invasive Species • Good Housekeeping – • Trash/Debris • Street Sweeping • Illegal Dumping • Sediment Management • Sediment Plumes • Mechanical Dredging
