3. Notice of Scoping for the City of Bridgeport, Combined Sewer Overflow Long Term Control Plan

Project Title: Combined Sewer Overflow Long Term Control Plan

Municipality where proposed project might be located: Bridgeport

Project Location: Southern Bridgeport, bounded to the north by US Rte 1.

Project Description: Bridgeport is a combined sewer overflow (CSO) community, where both sanitary sewage and stormwater are carried in a single pipe.  Approximately 28% of the municipality is served by combined sewers that are concentrated in the southern portion of Bridgeport; the oldest and most developed part of the city.  During rainfall events of sufficient intensity and duration the capacity of the combined system is exceeded and may overflow.  Built-in overflows were designed to prevent combined sewer flows from backing up into basements and surcharging onto streets. 

The CSO Long Term Control Plan recommends a combination of solutions to be implemented in phases over a 30-year period that will prevent overflows for the 1 year, 24 hour duration design storm (2.47" rain). The solutions include sewer separation, "green" technologies, a CSO Storage tank and relief sewers.  a re-evaluation of water quality and update to the plan will be conducted at 5-year intervals to determine the need for any modifications to the plan. 

An EIE for the "Facility Plan 2000 Report" was noticed on August 5, 2009 and addressed water quality improvements around the central section of the Pequonnock River and Ash Creek.  Project Phases 1-IV of the referenced LTCP have been completed pursuant to that report. 

The remaining phases are the subject of this scoping notice. Improvements under these phases incude:

Phase V: Improvements for Black Harbor's water quality

Phase VI and VII: Water quality improvements on the upstream portion of the Pequonnock River

Phase VIII: Cedar Creek, Bridgeport Harbor, and the final Pequonnock River improvement following the re-evaluation.

An update to the Long Term Control Plan schedule dated August 14, 2013 redistributed the phases by tasks as follows:

Phases I and II: Completed.  Design and Construction River Street Pump Station, Storm Water Pump Station, Congress Street Siphon Liner, and Lining and Sewer Separation Projects.  This is attributed to the Pequonnock River improvements and the phase included a monitoring program.

Phase III: Design and Construct Ash Creek Storage Tank

Phase IV: Design and Construct SEAB Storage Tank

Phase V: Water quality monitoring program for Ash Creek and Black Rock Harbor

Phase VI: Design and Construct Pequonnock CSO Relief Sewer

Phase VII: Water Quality Monitoring Program and Update the Long Term Control Plan

Phase VIII: Design and Construct Stage I and Stage II Storage system and follow with water quality monitoring.
