BACKGROUND
EXHIBIT A
Professional Services Agreement SW08 -01
Amendment 2
SCOPE OF WORK
The Port Angeles Landfill has been owned and operated by the City of Port Angeles
(City) since 1979. Three separate areas were developed within the landfill. The original
landfill area was closed in 1983 under WAC 173 -301. The second area was closed in
1990 under WAC 173 -304. Both the 301 and 304 cells are unlined. The third developed
area was lined, and is approximately 11 acres total. This area was closed in October of
2007 under WAC 173 -351. The landfill is now completely closed. All waste is
transferred to a site in eastern Oregon. The Port Angeles Landfill (PALF) is now
regulated by a Landfill Post Closure Permit issued by Clallam County Department of
Environmental Health and Human Services (CCEHS) on August 29, 2008. The Post
Closure Permit references the March 2008 Port Angeles Landfill Post Closure Plan. The
Post Closure Plan details the monitoring and maintenance requirements for the landfill in
its post closure period. This scope of work is based on those requirements.
Amendment 2 to the Professional Services Agreement SW08 -01 extends the work in
support of PALF Post Closure Permit compliance through 2011. The original task
descriptions are reiterated here. Three new tasks are added. These include an evaluation
of access and viability issues at monitoring well 3, an evaluation of the 304 compliant
landfill environmental monitoring and an evaluation of the landfill gas system. The
macro -algae survey was completed in 2010.
The budget for these services is presented in Exhibit B on a per -task basis.
Project invoices will be submitted to the City allocating incurred labor and expense costs
at the task level. Consultant travel to the City will be at the request of the City, and will
be a reimbursable expense to be charged against the applicable task.
TASK 1— COMPLIANCE AND REPORTING SUPPORT
This element of work will provide regulatory reporting and permit coordination for
landfill post closure operations. Work will include assisting the City with the preparation
of routine reports for submittal to CCEHS, to the Washington State Department of
Ecology (DOE) and other regulatory agencies. Reporting will be compiled so as to
achieve compliance with the Landfill Post Closure Permit and the Criteria for Solid
Waste Facilities (WAC 173 -351).
Task 1.1— Groundwater Reports
Exhibit A to Amendment 2— Professional Services Agreement SW08 -01
Scope of Work
Objective:
To assist the City with regulatory reporting related to groundwater monitoring as required
by CCEHS and DOE.
Activities:
1 Assistance in preparation of two (2) Semiannual Groundwater Monitoring Results
Reports. The City performs groundwater monitoring and creates time series plots,
trilinear diagrams, stiff diagrams, and potentiometric maps. The City also
calculates cation/anion balances, groundwater flow directions and rates of flow,
and compares the groundwater data to groundwater quality standards.
a) The Consultant shall indicate appropriate sampling times for the
new 304 compliant landfill monitoring wells based on previous
tidal study (Parametrix, 2008a) and sampling time (Aspect
Consulting, 2009a) memorandums.
b) Review and analyze the data provided by the City.
c) Write summaries and make recommendations for subsequent
groundwater monitoring events.
d) Assist the City in updating data spreadsheets for inclusion in the
Biannual and Annual reports, as needed.
e) Provide the statistical analysis of the sampling results.
f) Professionally certify and stamp all reports.
2. Preparation of the Groundwater Annual Report. The annual report for the landfill
in the past has been written in two sections. These sections represented the closed
landfill (landfill cells closed under 173 -301 and 173 -304 regulations) and the
active landfill. The 173 -351 landfill cells at the site were closed in October of
2007. In the Post Closure Permit, CCEHS lumps the 301 and 304 compliant cells
together and calls these the 304 compliant cells and then refers to the rest of the
landfill areas as the 351 compliant cells. Because the groundwater monitoring
requirements are different for the 304 and 351 compliant cells, it seems
reasonable to continue to divide the annual and the biannual report into two
separate sections to reflect the different post closure monitoring requirements.
The annual report should include the following for both 351 and 304 compliant
cells:
a) A summary of engineering and groundwater monitoring
activities for the previous year.
b) Summary tables containing 304 compliant and 351- compliant
landfill and leachate sample results.
Page 2 of 8
Exhibit A to Amendment 2— Professional Services Agreement SW08 -01
Scope of Work
c) Comparison of groundwater quality data to groundwater
standards, including Maximum Contaminant Levels (MCLs).
d) Conduct statistical analyses, and provide a summary of statistical
calculations and an update of Upper Prediction Limits (UPLs) for
the subsequent year.
e) Notification of any exceedences of UPLs or MCLs.
f) Calculation of groundwater flow rate and direction based on
potentiometric surface contour maps of groundwater level data.
g) An evaluation and recommendation of leachate indicator
parameters to be used in the subsequent data analysis program,
based on historical leachate chemistry and upgradient
groundwater chemistry. Leachate samples are analyzed for the
parameters indicated in Table 3 -2 of the Post Closure Plan.
h) Review of time series plots for leachate indicator parameters
(ammonia, chloride, chemical oxygen demand, dissolved iron,
dissolved manganese, nitrate, specific conductivity, total organic
carbon, vinyl chloride and dissolved zinc).
i) Analysis of well geochemistry based on trilinear plots of major
element composition, stiff diagrams and cation/anion balance
calculations in milliequivalents per liter.
j) Summarize and make recommendations for groundwater
monitoring for the next year.
The City will provide the Consultant with the appropriate data tables and figures from the
Groundwater Biannual Reports to facilitate creation of the Groundwater Annual Report.
Assumptions:
1. One round of comments from the City will be required to finalize the Annual and
Biannual reports. In addition, there are likely to be comments from the regulatory
Agencies to which response must be made.
2. The City will collect all groundwater samples and will contract for all required
laboratory analysis. The City will provide the Consultant with copies of all
laboratory and field data sheets for the sampling period. The City will update the
data spreadsheets with the laboratory results.
Deliverables:
Draft and final versions of the following reports:
2011 1 Semiannual Groundwater Monitoring Results Report
2011 2 °a Semiannual Groundwater Monitoring Results Report
2010 Annual Groundwater Monitoring Results Report
