SCOPE OF WORK.
CSO LONG TERM CONTROL PLAN UDPATE / INTEGRATED PLAN
GENERAL
The City of Nashua, NH developed and submitted a 1997 Long-Term CSO Control Plan and a
2003 Long-Term Water Quality and Infrastructure Control Plan to EPA and NHDES. Since
then, studies have been conducted to investigate more cost-effective measures to control CSOs
such as the Re-evaluation Study of CSO Control for CSO 005 and CSO 006 (March 2009).
These studies have resulted in modifications to some of the originally recommended elements
and associated implementation schedules that are in the current CSO Consent Decree Program.
The City has implemented all mandated CSO controls and has also developed and submitted a
CSO Post-Construction Monitoring Plan to EPA and NHDES. The EPA has since requested a
scope of work be developed for updating the Long-Term Control Plan in accordance with Clean
Water Act requirements.
The City is subject to the 2017 New Hampshire Small MS4 General Permit and has an ongoing
CMOM program for both the sewer and storm drainage systems. Through the integrated
planning approach as described in EPA’s "Integrated Municipal Stormwater and Wastewater
Planning Approach Framework,” a municipality, such as Nashua, can prioritize and schedule
wastewater and stormwater projects based on the municipality’s financial capability. This scope
of work is intended to comply with the EPA’s CSO Policy requirement for LTCP development,
and development of an Integrated Plan consistent with EPA guidance and CWA requirements.
