AMENDMENT TO MASTER AGREEMENT FOR PROFESSIONAL
CONSULTING SERVICES DATED NOVEMBER 12, 1992
TERMS AND CONDITIONS
All terms and conditions of Master Agreement for Professional Consulting Services
between City of Ukiah and EBA Wastechnologies dated November 12, 1992 shall remain
in force and effect except as modified by this and previous executed amendments.
Consultant is advised that the City is acquiring this service under special procedures
provided in its Municipal Code. The City is required to have a completed work plan for
landfill gas migration remediation within the operating record within sixty (60) days from
detection. The City is utilizing the date of the report (August 18, 1994) for Landfill Gas
Migration Monitoring Results as the date of detection. It is imperative and paramount that
the Work Plan for Landfill Gas Migration Remediation be submitted in final form to the
City no later than October 17, 1994.
AUTHORIZATION
Upon execution of this amendment, consultant is authorized to perform the work
described under "Scope -of- Work" of this amendment, on a time and expense basis not
to exceed the total amount of compensation indicated for each work task.
It is estimated that the installation of each gas monitoring well will be in the range of
$15,000 and that the cost of the Landfill Gas Remediation Work Plan is $10,000, for a
not -to- exceed total of $70,000. However, the cost for installation of monitoring wells is
likely to vary due to field conditions, with the consequent need for additional effort or level
of detail in the Landfill Gas Remediation Work Plan. Therefore, it is agreed that the cost
for each work task is intended to guide the budgeting and performance of the work, but
that funds may be shifted between tasks in order to complete the project, provided that
the total cost shall not exceed $70,000 without prior written approval by the City.
SCOPE -OF -WORK
Work Task II of Amendment to Master Agreement dated February 10, 1994 is hereby
amended by the addition of the following:
Task II - Perform gas monitoring well installation, field evaluation and gas testing related
to City's effort in determining the extent of any gas migration along the south boundary
line of the landfill. Consultant shall install Gas Wells GAS -1, GAS -2, GAS -3 and GAS -5
pursuant to the Landfill Gas Monitoring System Proposal Work Plan (August, 1994). All
work shall conform to applicable sections of 14 CCR and Subtitle D. Perform initial
reporting, monitoring and other required work as identified in the Landfill Gas Monitoring
System Proposal, Appendix C (August, 1994). Develop work plan describing the extent
of the gas migration problem and how it can be remediated. Total compensation for the
additions to this Task shall not exceed $70,000.
