Board of Public Works Meeting Date: May 25, 2022
Jeff Lafleur, Superintendent of Solid Waste
Caterpillar 826K Compactor Wheels and Teeth

To approve the purchase of a set of 4 wheels and teeth for the Caterpillar 826K
compactor from Caron Compactor Company of Escalon, CA in the amount of
$63,525. Funding through Department 168 Solid Waste; Fund: Solid Waste;
Account Classification: 54 Vehicle Repairs & Maintenance.

Caron quote.

The wheels and teeth on the all 4 wheels of the Caterpillar 826K compactor are
extremely worn and due for replacement soon. These replacements are necessary to
ensure good compaction of the waste coming into the landfill and to reduce
unnecessary wear on the compactor by requiring trash to be rolled more in order to
properly compact it.

It is cheaper and will require less down time to replace the wheels and teeth than to
have all of the old teeth removed and replaced individually.

The Solid Waste Department has used Caron’s compactor teeth on the last two
compactors and they have been proven to be both durable and reliable.

August 2021 EXHIBIT A

City of Nashua, NH
Capacity, Management, Operation and Maintenance (CMOM) and Stormwater Collection System
Investigation and Evaluation Program — Phase II
Scope of Work for Engineering Services

Background

The CMOM program was developed by the US Environmental Protection Agency (USEPA) as a flexible, dynamic
framework for municipalities to minimize the risk of SSOs by identifying and implementing widely accepted
wastewater industry practices to:

e Better manage, operate and maintain sewer collection system
e Investigate capacity constrained areas of the collection system

e Respond to SSO events to minimize impacts to human health and safety, and the environment

Since there is no Federal requirement, many states have been adding CMOM or CMOM-type requirements into
wastewater NPDES Permits, including New Hampshire. The EPA Region 1 and the State of New Hampshire
Department of Environmental Services (DES) requires the development of a “Collection System O&M Plan” as
part of its wastewater NPDES Permits that covers the pipes, manholes, and pump stations in the separate and
combined sewer systems.

During Year 1 and 2 of this program, the City of Nashua worked with Hazen and Sawyer (Consultant) to develop
the CMOM Program in a capacity to satisfy the conditions of the NPDES draft permit. Hazen delivered the
following items under the Year 1 and 2 contract:

e CMOM O&M Manual
Several Standard Operating Procedures
Prioritization of assets for inspection
Review and Rehabilitation recommendations for approximately 130,000 LF of Sanitary Sewer pipe,
43,000 LF of Storm Sewer Pipe, 2,500 LF of culverts, and all manholes associated with each
Expansion of the City’s Hydraulic Model
Stormwater BMP inspections
Rehabilitation recommendations for all eight siphons
Updates to the City’s GIS database

This document shall be used to continue with the development and implementation of the CMOM program for
the City of Nashua to guide employees on the proper preventative maintenance of their sewer collection and
drainage system. The CMOM Program is to help the City be proactive versus reactive to operation and
maintenance of its sewer systems, and thus mitigate costly repairs and potential violations to the Clean Water
Act. The CMOM program shall also serve as a tool for the City for budgeting future Capital Improvement
Projects. In addition, the City desires to develop a preventative maintenance plan for the drainage system.
While the drainage system is independent of the sewer collection system, both systems would benefit from an
operation and maintenance program. The Engineering scope of services provided shall be for a two-year period
for implementation of Nashua’s CMOM Program and continuation of the City’s Stormwater collection system
investigations and evaluations. Since this project is funded through an NHDES CWSRF loan, final approval of
work deliverables is required and will be submitted accordingly.
