This presentation will discuss two projects with outfall woes: one deals with the blockage of an emergency overflow on a residential road street, and the second with undersized drainage outfalls on an LPA transportation project.

The Lake County SMD initiated the Hunting Trail project to address ponding up to four feet in the sag of the Waterfowl Way. It also addressed basement flooding in the area. It will also describe obtaining easements for the work performed, dealing with unexpected situations, coordinating with adjoining projects, and handling sediment control.

The Massillon Road project improved a two-lane rural roadway section to a four-lane urban roadway section. An unintended consequence of these improvements was the existing undersized project outfalls would see additional flow from the proposed improvement. This project is an excellent example of addressing undersized outfalls early in a project to incorporate improvements into the plans to address the outfalls.

PFAS (per- and poly-fluoroalkyl substances) are a large group of man-made chemicals invented in the 1930s. They are now contaminants of concern in drinking water, wastewater, and stormwater. PFAS contamination comes from various sources and can cause serious health risks. PFAS are persistent in the environment and are known as the “forever chemicals”. Current stormwater regulations in Ohio do not require PFAS monitoring.

The 2021 draft of the US EPA Multi-Sector General Permit (MSGP) proposed regulations regarding PFAS; however, these regulations were not included in the final MSGP. It is anticipated that PFAS regulations will be addressed soon. 

This case study showcases an airport facility identified as a potential contributor of PFAS to the local municipal water system. It outlines the methodology for collecting stormwater samples for PFAS analysis and discusses the potential implications for similar industrial and airport facilities in Ohio.
