The City plans to continue to authorize Saturday and/or Sunday construction work to take place on the Peirce Island Wastewater Treatment Facility Upgrade. This is a continuation of weekend work that was authorized throughout the winter depending on the weather. The scheduling of weekend construction work will be determined weekly based on work sequencing, the weather and public events.
To better keep residents apprised of occurrences of combined sewer overflows (CSOs), the Portsmouth Sewer Division has introduced a Twitter feed, @PortsmouthCSOs, which will alert the community of overflows in real time.
As anticipated, the City has authorized work on the Peirce Island Wastewater Treatment Facility Upgrade to take place on periodic Saturdays and/or Sundays as weather permits during the winter season. The work will be limited to activities and equipment that do not generate excessive amounts of noise. No large construction vehicle traffic will be generated by this work.
In documents filed with the Environmental Protection Agency (EPA) on Friday, June 16, 2017, the City of Portsmouth reaffirmed its commitment to achieve further reductions in combined sewer overflow (CSO) discharges including those discharges to the South Mill Pond. In April 2017, the EPA commented on the City’s Post-Construction Monitoring Plan/Report (PCMP/R); on Friday, the City responded to those comments and submitted a Supplemental Compliance Plan.
