Board of Public Works Meeting Date: May 25, 2022
Daniel Hudson, P.E., City Engineer
Engineering Department
Amendment | for Municipal Separated Storm Sewer System (MS4) Assistance
To approve Amendment | to the engineering services contract for tasks required
by the EPA MS4 Permit with Hazen and Sawyer, PC of Manchester, NH in an
amount of $40,427. 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.
Hazen and Sawyer, PC (Hazen) was hired in 2021 to assist the City in completing
these tasks, including the development of the Annual Report.
The City has at least 359 publicly-owned stormwater outfalls that are required to
be screened during dry weather, and should discharge be occurring, the flow is to
be sampled and tested in an effort to identity illicit discharges connected to the
storm drain system. During 2021, 260 outfalls were screened. This amendment is
to provide funding to complete the screening of the remaining outfalls. Additional
funding is also needed to provide the screening results and analysis in the Annual
Report which is due in September 2022.
