…an Independent Special District
Protecting our community’s health and the environment by providing solid waste and sewer collection services.

To: Board of Directors
Via: Scott Carroll, General Manager
From: Rob Hamers, District Engineer
Date: October 24, 2013
Subject: Addendum No. 3 to National Plant Services Agreement for Annual
Sewer Mainline Cleaning
Summary
Beginning in the 2012-2013 fiscal year, the District began the practice of dividing the
yearly cleaning footage between the District’s contractor, National Plant Services, Inc.
(NPS), and District staff in order to utilize the District’s new sewer cleaning vehicle and
reduce program costs. Enclosed for Board consideration is a proposed addendum to
continue the cleaning program utilizing the shared cleaning concept.
As shown on the rate calculation sheet attached hereto, the District will save
approximately $100,867.94 by cleaning its portion of the system in 2013-2014.
Staff Recommendation
The Board of Directors a pp roves Addendum No. 3 to National Plant Services Agreement
in the amount of $123,891.02
Analysis
With the addition of the third maintenance worker, District field crews total four men
including the Maintenance Supervisor. The increase in field crew size coupled with the
recent purchase of a new sewer cleaning truck (VacCon truck) gives the District the ability
to perform regular sewer line cleaning. Shared cleaning saves the District substantial
money and also places the National Plant Services sewer cleaning vehicles inside the
District, which provides additional coverage in the event of an emergency.
ITEM NO. 19

The proposed addendum is for the fourth year of cleaning under the five -year contract
between the District and National Plant Services. The contract is very much in the favor of
the District as the pe r footage rates are very low and t he District has enjoyed a long -
standing mutually beneficial relationship with the company. As per the terms of the
agreement, NPS is eligible to receive an increase in their cost for service that equals
March to March Consumer Price Index (CPI) for Los Angeles, Orange and Riverside
Counties. The March 2012 to March 2013 CPI is 1.29%, which was added to the rates.
Strategic Plan Element & Goal
This item complies with the objective and strategy of Strategic Plan Element 1.0, Sewer
Infrastructure , whi ch states as follows :
”Objective: Our objective is to collect and transport wastewater to meet the needs of
existing and future customers.
Strategy: We will do this by the careful management of the collection infrastructure using
prudent planning and ma intenance, with financial strategies to maintain sufficient capacity
and respond to changing regulatory demands.”
Legal Review
Associate District Counsel prepared and signed the proposed Addendum No. 3 as
attached hereto.
Environmental Review
Sewer main cleaning has been previously determined by Counsel for the District to be a
maintenance activity, therefore, sewer main cleaning is categorically exempt under the
California Environmental Quality Act (CEQA) (Public Resources Code Section 21000 et.
seq.) un der Section 15301 Existing Facilities as “Class 1 consists of the … maintenance
… of existing public or private structures”, as further described in Section (b) as “Existing
facilities of both investor and publicly -owned utilities used to provide …. sewera ge …”
Financial Review
The fiscal year 2013 -14 budget for sewer line maintenance/cleaning is $220,000 and to
date no funds have been expended.
