City of Nashua, Public Works Division
Board of Public Works Meeting Date: January 28, 2021
Daniel Hudson, P.E., City Engineer
Engineering Department
EPA Municipal Separated Storm Sewer System (MS4) Assistance
To approve the engineering services contract for tasks required by the EPA MS4
Permit with Hazen and Sawyer, PC of Manchester, MA in an amount of
$187,550. Funding will be through Department: 169 Wastewater; Fund:
Wastewater; Activity: Stormwater Abatement.
The 2017 Municipal Separated Storm Sewer System (MS4) Permit, as issued by
the EPA, allows the City to discharge stormwater runoff to waterways in the City.
The EPA requires many documents to be generated, city properties to be
investigated, stormwater outfalls sampled and annual reporting provided as
examples of elements to be completed to comply with the city-wide permit.
In 2020, Hazen and Sawyer, PC (Hazen) assisted the City in developing the
Annual Report, a Stormwater Management Plan and an Illicit Discharge
Detection and Elimination program (IDDE) as well as completing inspections of
over 30 stormwater detention ponds. Hazen’s acquired knowledge of the City’s
system that treats and conveys stormwater to the waterways, and their
understanding of the reporting requirements of the MS4 permit, will enable them
to complete the required tasks for the City in a timely manner.
The City has been satisfied with Hazen’s overall performance to-date and this
contract will allow Hazen to continue to assist the City in meeting regulatory
requirements such as inventorying city-owned property stormwater discharges,
developing Stormwater Pollution Prevention Plans for pollution generating
properties, planning outfall sampling, and developing annual reporting.
