TO:
City Council
FROM:
Stan Gryczko, Assistant Public Works Director
Robert A. Clarke, Public Works Director
SUBJECT:
Amendment No. 2 to Consultant Agreement with West Yost Associates for
Groundwater Water Quality and Analysis
Recommendation
Approve the attached Resolution approving and authorizing the City Manager to execute
Amendment 2 to the consultant agreement with West Yost Associates to provide engineering
services to complete installation of groundwater monitoring wells and associated well
installation reports.
Fiscal Impact
The fiscal impact of this amendment is $20,000 which includes a 10% contingency. Funds are
budgeted in FY 14/15 as part of Wastewater Program 7320 (Utility Resource Management).
Council Goals
This effort supports the City Council goals to;
• Maintain and improve the infrastructure.
• Conserve natural resources and protect the environment.
Background and Analysis
The request for additional funds is to complete the installation of monitoring wells, and
associated well installation reports, to allow the City to assess existing background water quality
in the region surrounding the Wastewater Plant (WWTP). This monitoring and analysis is
required by the existing WWTP discharge permit.
In May 2009, the City Council authorized an Agreement with West Yost Associates to 1)
Evaluate agricultural use of treated wastewater on area lands and 2) Prepare a groundwater
quality report. These efforts were required as part of an agreement with the Regional Board
(Board) to approve a two year extension to the final compliance date for new facility upgrades.
In July 2010, staff presented information to Council detailing why re-use on agricultural land in
close proximity to the WWTP was not a feasible long-term solution for treated wastewater
disposal. Council agreed with the staff recommendation to no longer pursue this option, due to
cost and resistance to use of treated wastewater. Staff informed the Board of this decision in
September 2010. Additionally, the Board was informed that a background water quality report
would require the installation of monitoring wells off-site and additional time would be required
for this effort. Based on this information the WWTP discharge permit was amended to include

05D - 1
additional time to prepare a work plan, monitor the groundwater, and prepare a water quality
report. Based on these new requirements, Council approved Amendment 1 to the original
Agreement in October 2010.
In November 2011, a Wastewater Treatment Plant Background Monitoring Well Installation
Work Plan was submitted to the Regional Board. The work plan required monitoring wells offsite in order to properly assess the quality of existing groundwater in the area. Staff attempted to
gain easements on private land to install monitoring wells but were ultimately unsuccessful. A
revised work plan was submitted in October 2012 recommending off-site monitoring wells on
existing City property. Board staff had a number of questions regarding the revised work plan;
most related to the new location of off-site monitoring wells. Based on this feedback and
modified requirements in a newly adopted WWTP discharge permit (2013), an updated work
plan was submitted for Board staff approval in November 2013. The newly revised work plan
included:
• Destruction and replacement of an existing monitoring well at the WWTP.
• Construction of two new wells on city property (off-site) for background monitoring
• Evaluation of existing wells not owned by the City but within the vicinity of the WWTP
The City received approval to complete destruction and replacement of the existing monitoring
well and began this work in March 2013. In December 2014, the City received formal approval
of the work plan and was instructed to proceed with the installation of two new off-site
monitoring wells.
The request for additional funds is necessary as the original agreement and first amendment did
not include multiple work plan submissions nor anticipate changing permit requirements. The
amount requested will complete this agreement and enable the City to begin sampling and
analysis of background groundwater quality, using an approved work plan, and compare it to
groundwater quality under the existing WWTP.
