  1. CLARK COUNTY UTILITIES Storm Water Management Plan- Employee Training September 2004

  2. SW WWTP Aerial View

  3. Why an Employee training program for storm water? • Required by General Permit for Industrial Stormwater for County’s Southwest WWTP • And Phase 2 NPDES Storm water Permit for Clark County

  4. Why an Employee training program for storm water? • Required by General Permit for Industrial Stormwater for County’s Southwest WWTP • And Phase 2 NPDES Storm water Permit for Clark County

  5. Why an Industrial Permit for Stormwater at WWWTP? If the lift station fails at the oxidation ditch, the overflow discharges directly to the creek, triggering need for coverage under Industrial Permit.

  6. WHEN IT RAINS • Public Education/Outreach on Storm Water Impacts • Public Involvement/Participation • Illicit Discharge Detection & Elimination • Construction Site Storm Water Runoff Control • Post-Construction Storm Water Management • Pollution Prevention/Good Housekeeping for Municipal Operations IT DRAINS The Feds get involved In response to the pollution hazards caused by storm water runoff, the Environmental Protection Agency passed Phase II of the federal Clean Water Act. To comply with this regulation, the Board of Miami County Commissioners and other political subdivisions have coordinated efforts to develop Storm water Management Programs so that pollution caused by runoff in Miami County can be minimized as much as possible. The Storm Water Management Program consists of the following six components, which are targeted for implementation by the end of 2007:

  7. WHEN IT RAINS IT DRAINS Where does storm water runoff go? Commercial Development Residential Development Water Treatment Plant

  8. WHEN IT RAINS IT DRAINS What is a watershed? A watershed is all the land area that drains to a given body of water. WE ALL LIVE IN A WATERSHED

  9. CCUD Stormwater Permit timetable: • Permit issued March 2003 • Required Stormwater Management Plan by March 2004 • Permit requires full implementation of Plan by September 2004 (including employee training program)

  10. Employee Training Modules: 1. Awareness level – what is stormwater pollution? What are the causes? Why is it important to address it? 2. Detailed training required to implement WWTP stormwater plan.

  11. What does the Employee Need to Know for Industrial Permit? • Overview of permit • Goals of Stormwater Management Plan • Pollution Prevention (P2)/ Good Housekeeping • Preventive Maintenance practices • Spill Prevention and Response

  12. What Does Employee Need to Know Cont’d • How to conduct inspections • Performing inspection follow-up • Reporting and recordkeeping • Procedures, Maintenance and Inspection of site specific areas

  13. WHEN IT RAINS IT DRAINS After the Storm A Guide to Understanding Storm Water Runoff

  14. WHEN IT RAINS IT DRAINS So what’s the big deal? As storm water flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants, and empties into a storm water collection system. Anything that enters a storm water collection system is discharged untreated into the lakes and rivers we use for swimming, fishing, and providing drinking water. Now that point-source pollution has been remediated, polluted runoff currently ranks as one of the nation’s greatest threats to clean water.

  15. 1. Identify team and responsibilities 2. Description of potential pollution sources which could contaminate storm water. What’s in the SWMP?

  16. What’s in a SWMP? 3. A Site Map showing: -outline of drainage area for each outfall -existing structural control measures -surface water -locations where significant materials are exposed to precipitation -locations where major spills occurred

  17. SITE MAP CONTD: Locations of these activities which are exposed to precipitation: fueling stations, vehicle and equipment maintenance or cleaning, loading/unloading, locations for treatment, storage or disposal of wastes, liquid storage tanks, processing and storage areas A flow direction and types of pollutants that could contaminate runoff.

  18. What’s in a SWMP? 4. Inventory of materials that potentially could be exposed to precipitation. Include where materials were handled, treated, stored, or disposed that were exposed to storm water in last 3 years.

  19. What’s in a SWMP? 5. List of significant spills and leaks of toxic or hazardous pollutants in last 3 years.

  20. What’s in a SWMP? 6. Risk identification and narrative – show inventory of materials with potential to contaminate storm water.

  21. What’s in a SWMP?7. Measures and Controls Good Housekeeping – maintain clean, orderly facility Preventive Maintenance – inspection and maintenance of storm water devices, inspecting and testing equipment and systems, perform proper maintenance

  22. WHEN IT RAINS IT DRAINS So what can Average Joe Employee do? If each of us does our small part in preventing storm water pollution, the results will be significant. There’s a part we can play in each of the following areas: • Household Waste Disposal • Lawn Care • Auto Care • Water Conservation

  23. Measures and Controls Contd: Spill Prevention and Response – identify areas where spills can occur, list material handling procedures, storage requirements, procedures for cleaning up spills, have necessary equipment for clean up.

  24. Measures and Controls Contd: Inspections -inspect designated equipment and areas at appropriate intervals. Must have tracking systems and follow up on items found in inspections, must keep records

  25. Measures and Controls Contd: Employee Training – inform employees of responsibilities and goals of plan, provide training on spill response, good housekeeping, materials management, specify periodic dates. Contractor Training – not required but is advisable Recordkeeping and Internal Reporting – keep records of spills, other discharges, inspections and maintenance.

  26. Measures and Controls Contd: Plan must include certification that the facility was evaluated for non-storm water discharges. List any non-storm water sources and identify pollution prevention practices.

  27. WHEN IT RAINS IT DRAINS Remember...

  28. 8. Perform a Comprehensive Site Evaluation Conduct at least yearly Visually inspect material handling areas for potential sources of pollution Observe catch basins, swales Visual inspection of equipment needed to implement the plan.

  29. Perform a Comprehensive Site Evaluation Contd: Make any necessary revisions to plan within 2 weeks following the site evaluation Timely implement any changes needed, but no later than 12 weeks after site evaluation. Prepare summary report of site evaluation with signature.

  30. HAZARDOUS WASTE Insecticides, pesticides, paint, solvents, used motor oil and other auto fluids can poison aquatic life. Land animals and people can become sick from eating diseased fish or ingesting polluted water.

  31. 9. Records Retention Retain plan for life of permit Keep reports and records for minimum 6 years.

  32. 10. Plan Updates Plan must be updated for any change in design, construction, operation or maintenance which has significant effect on, or the potential for discharge of pollutants in storm water, of if the plan is ineffective in minimizing storm water pollutants

  33. 11. Duty to Comply Permittee (the County) must implement the measures in the Plan Permittee must comply with all conditions of the Permit. Duty to take action to minimize effects of a spill or accident (duty to mitigate)

  34. Duty to Comply Contd: Duty to provide information to Ohio EPA if requested Duty to perform proper operation and maintenance

  35. Harm fish & wildlife populations Kill native vegetation WHEN IT RAINS Foul drinking water supplies IT DRAINS Degrade the watershed in which we live If left uncontrolled, these pollutants can:

  36. PROPER MATERIALS INVENTORY • OBJECTIVE: To identify all significant materials which may be exposed to precipitation.

  37. PROPER MATERIALS INVENTORY Significant materials means process chemicals, raw materials, fuels, pesticides, or other toxic materials.

  38. PROPER MATERIALS INVENTORY CONTD: SW WWTP sources include: Raw or partially treated wastewater Biosolids Chlorine Diesel fuel Used motor oil and antifreeze Hydrofluoric acid Hydrogen peroxide

  39. PROPER MATERIALS INVENTORY CONTD: Materials inventory is an ongoing process Records must be continually updated

  40. Steps to conduct Materials Inventory: Identify all chemical substances in the workplace Walk through the plant

  41. Steps to Conduct Materials Inventory Review purchase orders from previous year Compile MSDS for each chemical

  42. Steps to Conduct Materials Inventory Label all containers to show name and type of substance, stock number, expiration date, health hazards, handling instructions. (Much of this was done for the Hazard Communication Plan) Clearly mark on the inventory which hazardous materials require special handling, storage or disposal techniques.

  43. Using the Materials Inventory Identify which items were exposed to precipitation in the last 3 years Identify steps that can be taken to eliminate possible exposure to storm water

  44. PREVENTIVE MAINTENANCE = A BEST MANAGEMENT PRACTICE

  45. The Great Miami River Watershed WHEN IT RAINS IT DRAINS

  46. Construction & Agricultural Sediment Oil, Grease & Toxic Chemicals from Motor Vehicles Pesticides & Nutrients from Lawns & Gardens WHEN IT RAINS IT DRAINS Viruses & Bacteria from Pet Waste & Failing Septic Systems Heavy Metals from Roof Shingles, Motor Vehicles, etc. Possible pollutants in storm water:

  47. Visual inspection is a Best Management Practice (BMP )which may identify a variety of problems. Used to: Look at runoff for signs of contamination Look at outfalls in dry weather for signs of contamination . Look at storage areas for leaks or stains VISUAL INSPECTION

  48. VISUAL INSPECTION Wet weather inspections should be conducted during the first hour of a storm event. Look for presence of: • Floating or suspended material • Oil and grease • Discoloration • Turbidity • Foam • Odor

  49. Visual Inspections Dry weather inspections of outfalls: • Look for stains, sludge, odor or abnormal conditions Inspection frequency should be done monthly, and cover both wet and dry conditions.

  50. Visual Inspections Visual inspection of storage and processing areas in the plant, focus on: • Storage areas • Loading and unloading areas • Pipes, pumps, valves, fittings • Tanks – look for signs of corrosion inside and outside tanks Inspect foundation for deterioration • Containment areas • Shipping containers
