By the day time staff and again during the Pm “evening” walk though done by the evening staff. In the event that the influent gate is not 100 % open due to wet weather conditions the Water pollution control staff will make every effort to treat as much water as possible not to exceed plant capacity. The staff is then required to monitor the CSO on an hourly basis during normal staffing hours. In the event of a CSO occurrence at 806. East Broadway. EPA Permit number 2PB00033 Outfall 002 Lat.41°-10’-52.9” N. Long.83°-39’-49.1”W. The water depth is measured and calculated to give the operator an estimated flow. This procedure is done on an hourly basis until the CSO outfall is closed during normal staffing hours.

Tributaries

The Rocky Ford Creek is a tributary of the portage river by way of middle branch and south branch. The village of North Baltimore WWTP effluent and CSO enter the Rocky Ford Creek approximately twenty (20) miles upstream of the confluence of South branch with the main stem of the Portage River. The Portage River at this point is approximately thirty-six (36) miles upstream of Lake Erie. The Rocky Ford Creek from North Baltimore to the point where it joins the Portage River generally flows through agricultural areas thus there is low probability of the Rocky Ford creek being used for contact recreation. There are no water intake structures within Five hundred (500) feet of the CSO outfall. Thus there is no public entities or Indian tribes that would be impacted by a CSO discharge.

What the village of North Baltimore has done to reduce CSO occurrences

In 2012 the village started phase I of the sanitary sewer separation which included the entire south side of the village. This phase of construction also included running the main trunk on the north side of town down East Broadway. This project was completed in 2012 . In 2013 the village started phase II of the sanitary sewer separation which included the entire north side of the village. This project was completed in 2014. After these projects were completed the pollution control plant seen a dramatic decrease in flow. So a plant upgrade was needed. This project started in 2015 and was completed in 2016. With a new lab built, variable speed pumps installed and a completely updated electrical system including an updated SCADA system.

2018 The village received 41.15 inches of rain and 23.2 inches of snow. The village of North Baltimore is proud to announce that we did not have any CSO or Combined Sewer Overflow for the calendar year of 2018.

The Pollution control facility aka sewer plant still receives heavier flows at times when we get rainfall or snowmelt. The village will be looking at replacing some old manholes, raising and sealing manholes in low lying areas. The village also will be doing bacteria on the storm line to make sure we are not sending untreated sanitary sewer to the waterways. These projects will help the village to ensure that we do not have any CSO and the village is doing its part to keep the waterways clean.
