REGION 5 Lead Inspector, Dean Maraldo, and Inspectors Joan Rogers and Ted Flatebo arrived at the City of Cahokia Heights' (the "City") engineering consultant's (Hurst-Rosche) office at 5 Bank Square in East St. Louis at 02:30 PM (CT) on 04/05/2022. REGION 5 Lead Inspector presented his credentials to Terry Sudholt (HurstRosche) and informed the group that after the opening meeting we planned to inspect known areas of concern in the City's sanitary sewer system. The table above identifies the attendees that participated in the meeting and field inspection. This report is based on information supplied by City of Cahokia Heights representatives and observations made by the REGION 5 inspectors, including: direct observations made by the REGION 5 Inspectors, photographs taken by REGION 5 inspectors, and verbal or written statements made by information supplied by City of Cahokia Heights representatives during or subsequent to the on-site Inspection. After opening introductions, I asked the group for a sewer funding update. Jim Nold (Hurst-Rosche) mentioned that the City has been working with congressional representatives regarding assistance with sewer infrastructure issues, and specifically with funding support for sewer trunk line and pump station projects and projects that will help separate the sewer collection system from the East St. Louis system. The City representatives discussed potential plans for a 3.5 mile long sanitary trunk lining (Jerome Lane) for a critical portion of the City's collection system. I asked the City representatives about status of the ongoing SSO discharge at 82nd street. Dennis Traiteur said he believes the SSO discharge at N82nd Street was still attributed to surcharging of the East St. Louis collection system. Prior to concluding the opening conference, I asked about the City's MS4 permit status. The City representatives did not know if the City was currently covered under any MS4 permit, and said they would look into it. At this point we concluded the opening conference and discussed the afternoon's plan to observe several areas of concern in the sanitary sewer collection system. The City representatives chose not to join us for the field observations. After concluding the opening conference, we met with the U.S. Army Corp of Engineers representatives to discuss the plan for observing SSO areas of concern, and departed for the first location, the point where the 2 of 7 City of Cahokia Heights Inspection Date(s): 04/05/2022 - 04/08/2022 City's system flows to the East St. Louis system in the vicinity of N82 Street and Ridge Ave. Facility/Site Information Location(s) Location N82nd and Ridge N82nd Street SSO Lady of Snows Lift Station Lauralee Drive Area Former Village of Cahokia Lift Station 5 (rear) Description Point where the City's collection system enters the East St. Louis collection system.
