Hi,

This is the letter I’m planning to send in response to David Cole along with the updated Section 2.1 of the I/I Plan. The updated paragraph is below. Please let me know if you have any comments. I would like to respond by Friday before.

2.1 No I/I Historical Sewer System Overflows

The City of Molalla has had no known historic sewer system overflows (SSOs) associated with I/I since January 2006. The City does not presently have concerns that I/I related SSOs are likely nor has the Department of Environmental Quality expressed concern with the potential for I/I related SSOs in the City’s collection system. In many Oregon cities, SSOs are a driver of I/I assessment and reduction programs because I/I often overwhelms the older collection systems present in many communities. Molalla does not have such a situation. The City’s collection system and wastewater treatment plant is generally able to handle the wastewater quantities flowing into the wastewater treatment plant without any I/I related SSOs occurring.

Thanks,

JC
