  1. IDDE Scenario Introduction The following presentation and scenarios are a supplement to the August 2008 NEWSC IDDE Training Power Point Presentation and the Group “A” Scenario Interactive Presentation. This is to be used as a guidance tool to aid in how to potentially respond to illicit discharge being reported. Select a scenario from the following index slides and walk yourself through the situations.

  2. IDDE Scenarios • General Scenario Overview Table • Do-Do-Do’s and Do-not’s • Lawn Clippings • Where’s that smell coming from? • Managing restaurant waste anyone • The red creek • The special formula • Questions • Exit

  3. Scenarios NO YES NO YES NO YES NO YES NO YES NO YES NO YES NO YES NO YES Return to Scenario Index

  4. Do-Do-Do’s and Do-not’s An individual calls stating that they saw someone else leaving pet waste on the side of the road, sidewalk or worse disposing of it at in the storm sewer inlet. What should you do? Click for next slide

  5. Do-Do-Do’s and Do-not’s Cont’d. NO YES Recommended Action: Fill out Initial Contact Form? Call 911? Notify the Illicit Discharge Coordinator? Call Municipalities Operation Department to assist in providing storm sewer information? Contain and identify the unknown substance? Find the source of the discharge? NO YES NO YES NO YES NO YES NO YES Click for next slide

  6. Do-Do-Do’s and Do-not’s Cont’d. Gather information on the Initial Contact Form and route to the Illicit Discharge Coordinator to have, in most cases, an educational moment. This is a practice that should be discouraged however, is not an emergency. Pet Waste should be disposed of in a safe and environmentally correct manner, such as: burying, flushing or disposing of in the trash; as recommended within a UW-Extension pamphlet. Check local ordinances to see if any of these solutions are prohibited. Recommended Action: Return to Scenario Index

  7. Grass Clipping Scenario Someone calls stating that he/she saw someone putting grass clippings into the storm sewer inlet or into the road. What should you do? Click for next slide

  8. Grass Clippings Cont’d. NO YES Recommended Action: Fill out Initial Contact Form? Call 911? Notify the Illicit Discharge Coordinator? Call Municipalities Operation Department to assist in providing storm sewer information? Contain and identify the substance? NO YES NO YES NO YES NO YES Gather as much information as possible on the Initial Contact Form and route to the Illicit Discharge Coordinator so that an educational moment can be shared. Return to Scenario Index

  9. You receive a phone call from a resident stating that there is a strong petroleum gas smell coming from the conservancy and creek behind their place of residence…….What do you do? What’s that Smell? Click for next slide

  10. What’s that Smell Cont’d. NO YES Recommended Action: Fill out Initial Contact Form? Call 911? Notify the Illicit Discharge Coordinator? Notify WDNR? Contain and identify the unknown substance? NO YES NO YES NO YES NO YES Find the source of the substance? Call Municipalities Operation Department to assist in providing storm sewer information? NO YES NO YES Click for next slide

  11. What’s that Smell Cont’d. Upon receiving the phone call, the fire department was dispatched. It was determined that a petroleum odor was emitting from the storm sewer, which discharges to an open channel. However, there were no signs of petroleum product on the water surface. An investigation of the storm sewer system in the immediate area revealed no notice able signs of discharge taking place. This was an unexplainable occurrence and was chalked up as such, as there were no obvious signs of environmental concerns. HOWEVER……...a year or so later…… IT’S BACK …….and …… Click for next slide

  12. What’s that Smell Cont’d. …..this time the municipality was contacted by the WDNR. The home owner contacted the WDNR directly. The WDNR also did some investigation and came up with no obvious signs of a petroleum discharge. However, they did point their finger at the municipality. The WDNR suspected that an old underground petroleum tank was located within 1960 Aerial Photo the road at the location of an old gas station, as seen within an old aerial photo. There was no written documentation to show that the tank had been removed. By comparing the aerial photograph with the location of the storm sewer it was concluded that the tank would have been encountered and thus removed during construction. SO, now what? 2000 Aerial Photo Click for next slide

  13. Former Gas Station Former Gas Station

  14. What’s that smell and where’s it coming from?

  15. What’s that Smell Cont’d. The logical location of a source of petroleum discharge was the newer gas station. Both the station owners and the WDNR looked at the records and concluded that they were within acceptable limits and no appreciable release could be taking place. After much discussion amongst all parties, a conclusion was made that the odor arose after significant rain 1960 Aerial Photo fall events Indicating that there may be an old tank buried further up-stream. Multiple locations were identified. During the next large rain event members of the WDNR, Coast Guard, Emergency Management, municipal operation, fire department and engineering staff came out and manned these locations in an attempt to observe a discharge. To no avail. SO, now what? 2000 Aerial Photo Click for next slide

  16. What’s that Smell Cont’d. It was determined a confined entry was to be performed in the large storm sewer at the location of the gas station. The inspecting individual noted some staining at some joints on the inside walls of the sewer in the proximity of the gas station. As it turns out, the gas station did have a problem with a seal on one of their pumps. Every time it rained, the water got into the pump pit and co-mingled with the petroleum. The water then found it’s way through various trenches until it reached the outside of the storm sewer. The joints on the storm sewer were not water tight and the contaminated water entered. As the water would rush through the storm sewer it would mix and create the odor. The seal has since been fixed. 2000 Aerial Photo Return to Scenario Index

  17. Restaurant Waste Disposal Ever wonder what a restaurant does with the food and garbage that was left on your plate when you leave? Most people would assume that it gets dumped into the garbage, ultimately a dumpster, but that is not always the case. While doing routine maintenance of a storm sewer line, the sewer maintenance crew noticed paper and food scraps in a storm manhole. What should be done? Click for next slide

  18. Restaurant Waste Disposal Cont’d. NO YES Recommended Action: Fill out Initial Contact Form? Call 911? Notify the Illicit Discharge Coordinator? Notify WDNR? Contain and identify the unknown substance? Find the source of the substance? Call Municipalities Operation Department to assist in providing storm sewer information? NO YES NO YES NO YES NO YES NO YES NO YES Click for next slide

  19. Restaurant Waste Disposal Cont’d. Because this was called in by City operational staff, they were not required to be contacted. Also, this did not warrant calling the fire department. The City’s plumbing inspector was called to assist in the investigation as to the source of the food and grease. The WDNR was notified of the incident, to keep them informed of the findings and outcome. The WDNR indicated that they would not be coming out to assist. It was a short search, as there was only a single restaurant located immediately up-stream of this manhole. There were also signs of recent washing activities taking place. The restaurant’s common practice was to rinse out bus bins and garbage cans in the outside dumpster enclosure which drains directly to the storm sewer inlet in their parking lot. Click for next slide

  20. Restaurant Waste Disposal Cont’d. The restaurant was notified they must develop a policy including employee training to prevent this practice from happening again in the future. They were also directed to jet and vacuum out the next four down stream reaches of the storm sewer. The WDNR was happy with these findings, recommendations and results. Return to Scenario Index

  21. Special Formula You are informed by the WDNR that there is a large petroleum sheen on the Fox River located in a specific area. The sheen was reportedly half of the river wide and approximately a quarter of a mile long. What would you do? Click for next slide

  22. Special Formula Cont’d. NO YES Recommended Action: Fill out Initial Contact Form? Call 911? Notify the Illicit Discharge Coordinator? Notify WDNR? Contain and identify the unknown substance? Find the source of the substance? Call Municipalities Operation Department to assist in providing storm sewer information? NO YES NO YES NO YES NO YES NO YES NO YES Click for next slide

  23. Special Formula Cont’d. The WDNR contacted you because the initial contact form was not filled out, nor was the Fire Department contacted at this time. Prior to leaving the office to meet the WDNR, maps of the storm sewers and their outfalls were gathered. Upon arriving on site, a quick walk along the shoreline narrowed the search for which outfalls should be investigated further. The obvious location to start investigating was an outfall immediately adjacent to an active construction site. This was the most significant portion of the sheen in the area. Upon checking the up-stream manhole there was no evidence of a flow in this manhole. Because this event was located on the Fox River, a Federal waterway, the US Coast Guard was called onto the scene along with the local emergency management. With no flow coming from up-stream the search was narrowed to the construction site. Members of the Coast Guard, WDNR and Fire Department searched the site for signs of a discharge; none were observed that evening. It was determined to take an additional look in the morning. While searching, the local Hazmat team placed booms in the river to prevent further discharge. Click for next slide

  24. Special Formula Cont’d. In the morning, construction activities were already underway. While walking around it was noted that near an inlet there was a red discoloration and a small sheen which started near a concrete pumper truck. Talking with the operator, he indicated that the red stuff on the ground was his “Special Formula” to lubricate the chute and pipes on his machine. The “Special Formula” was comprised of 1/3 Kerosene, 1/3 Brake Fluid and 1/3 Hydraulic Fluid. Click for next slide

  25. Special Formula Cont’d. The operator stated that he has used this on all of his machines, allows it to flow onto the ground all of the time, and didn’t understand what the problem was. The WDNR educated this operator and the company he worked for with a redeemable educational coupon (a.k.a. citation). Return to Scenario Index

  26. The Red Creek What do you get when a company builds overtop of a 24” storm sewer with a bulk process storage tank that develops a leak? PROBLEMS!!!! Click for next slide

  27. The Red Creek Cont’d. NO YES If you received a call of this nature, what would you do? Fill out Initial Contact Form? Call 911? Notify the Illicit Discharge Coordinator? Notify WDNR? Contain and identify the unknown substance? Find the source of the substance? Call Municipalities Operation Department to assist in providing storm sewer information?

  30. The Red Creek Cont’d. In this particular case, the WDNR was notified via an anonymous call to their Spills Hotline. A warden went out to investigate the complaint. The information received from the initial call was flawed but the warden continued looking and finally observed in a creek, a red flow of, what appeared to be blood tainted water. The tainted water was being discharged from the local municipalities storm sewer system. The warden called the local municipalities Department of Public Works for assistance in locating the source. After opening a few manholes it was determined that the source was a local slaughter house. Now that a responsible party was identified, three things needed to happen. 1. Stop the flow into the creek. 2. Clean-up the creek and storm sewer to prevent continued contamination. 3. Identify how the substance was getting into the storm sewer system. Click for next slide

  31. The Red Creek Cont’d. The company hired other companies to plug the storm sewer, clean the creek and storm sewer, and investigate the source of inflow into the storm sewer system. Closed circuit television was used to determine where the flow was coming into the sewer. After obtaining the footage from the televising, they could then determine where in the building it was originating from. As it turns out, there was a small crack in a sump pit that was directly over the storm sewer. The storm sewer isn’t water tight; with the added water weight, infiltration was able to take place. The crack in the pit has since been repaired. Return to Scenario Index
