Percentage of CSO volume reduction expected with the implementation of the Long Term Control Plan (system-level)

At an individual system level, this metric shows the expected reduction in volume (million gallons) of annual combined sewer overflows (CSOs) for the permittee based on the proposed Long Term Control Plan (LTCP). This percentage is calculated based on two values reported in the LTCP: A) the baseline annual volume of CSOs and B) the anticipated annual volume of CSOs after LTCP implementation. The equation used is: 1 - (B/A). Given that all permittees will meet the minimum requirement of the CSO permit, which is 85% capture* (a separate calculation that factors in the wet weather flow volume at the treatment plant), this metric gives a sense of how far away the permittee is from achieving 85% capture.

Note: More information about the CSO permits and the plans for all 24 permittees that submitted Long Term Control Plans (LTCPs) in October 2020 can be found here.

*The "Presumption Approach” in US EPA’s CSO policy requires “…the capture for treatment of no less than 85 percent by volume of the combined sewage collected in the combined sewer system during precipitation events on a system-wide annual average basis.”
