BACKGROUND
EXHIBIT A
Professional Services Agreement SW08 -01
Amendment 3
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 3 to the Professional Services Agreement SW08 -01 extends the work in support of
PALF Post Closure Permit compliance through 2014. The original task descriptions are reiterated
here.
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 (Two Groundwater Semiannual Reports per Year and
one Groundwater Annual Report per year)
Professional Services Agreement, Page 3 2/24/2012
SW08 -01, Amendment No. 3
Objective:
To assist the City with regulatory reporting related to groundwater monitori as required by
CCEHS and DOE.
Activities:
1. Assistance in preparation of the two Semiannual Groundwater Monitoring Reports.
The City performs groundwater monitoring and creates contaminate tables, time series
plots, trilinear diagrams, stiff diagrams, and the potentiometric map. The City also
calculates cation/anion balances, groundwater flow direction and rate of flow, and
compares the groundwater data to groundwater quality standards.
a) The Consultant will review and analyze the data provided by the City,
and
b) Write summaries and conclusions and make recommendations for
groundwater monitoring.
c) As needed, the Consultant will assist the City in updating data spreadsheets
for inclusion in the Biannual and Annual reports.
d) The consultant will sign and stamp the report.
2. Preparation of the Groundwater Annual Report.

c) Copies of statistical calculations and summaries, notification of any
statistical increase in analyte concentration and/or notification of any
analyte concentration above maximum contaminate levels (MCLs)
d) A calculated groundwater flow rate and direction of flow for the sampling
period
e) A comparison of the groundwater data to groundwater quality standards
f) An evaluation and recommendation of leachate indicator parameters
to be used in reporting. Leachate samples are analyzed for the parameters
indicated in Table 3 -2 of the Post Closure Plan.
g) Review of past 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) and plotting of current data.
h) Conduct statistical analysis with current data as described in the current
SAP plan.
i) Perform a trilinear plot of major element composition of the
groundwater for each well for the sampling period, stiff diagrams and
cation anion balance calculations in milliequivalents per liter for each
well. Analyze the well geochemistries.
j) Summarize and make recommendations for groundwater monitoring for
the next year.

Task 2 Technical Support
This element of work will provide support for unforeseen issues which may develop at the
landfill.
Task 3 Macro Algae Survey
Objective: To survey the algae in front of the seawall as required by the Post Closure Permit.
Activities:
Subtask 3.1- Macro Algae Habitat Survey
0
Perform a macro algae survey using the WDFW Intermediate Eelgrass/ Macro algae Habitat
Survey guidelines (WDFW 2006). The survey will be performed on the shoreline along a
revetment wall constructed on the north side of the landfill, at the bottom of a bluff on the
Strait of Juan de Fuca. For consistency purposes, the survey area will be the same as the area
previously surveyed in 2010.
The survey will be performed along nine transects placed perpendicular to the shoreline and
spaced at approximately 100 -foot intervals, covering a total of 800 feet of shoreline. Along
each transect, data will be collected at 20 -foot intervals if feasible, given the potential site
conditions (shallow water depths and dense kelp forests) encountered by Parametrix in 2006
while performing the baseline survey (Parametrix 2008). If not feasible, data along each transect
will be collected every 100 feet through the alternative (or similar) approach used by Parametrix
in 2006 (Parametrix 2008). The use of an alternative survey approach (if needed) will be
coordinated with WDFW.
Data to be collected in the macro algae survey include:
Characterization of the substrate along each transect
Macro algae percent cover per 0.25 m at the 2, 6, and 10 o'clock positions
Eelgrass shoot counts (if any present) per 0.25 m at the 2, 6, and 10 o'clock
positions
Kelp holdfast counts per 0.25 m at the 2, 6 ,and 10 o'clock positions
Presence of easily observed macro invertebrate and vertebrate species
Turbidity /visibility
Time and depth.
The density count for each 20 -foot interval location will be the average of the three individual
counts for both macro algae and eelgrass.
Professional Services Agreement, Page 7 2/24/2012
SW08 -01, Amendment No. 3
The location of each transect will be the same as those established during the 2010 survey.
Along each transect, the landward intertidal areas will be surveyed by an observer from shore
and divers will perform the subtidal portion of the survey.
Assumptions
Unless otherwise approved by WDFW, the macro algae habitat survey will be
conducted between June 1 through October 1 in accordance with the WDFW
Intermediate Eelgrass/ Macro Algae Habitat Survey Guidelines.
Given the availability of suitable tidal conditions to perform the underwater
portion of the habitat survey, divers may need to visit the site for up to four
different days during high tide conditions.
Based on the baseline habitat survey performed by Parametrix in 2006, eelgrass is
not present within the survey area and therefore, the time estimated to
performed counts reflects this assumption.
Data will be collected along each transit at 20 -foot intervals if feasible. If not
feasible, data will be collected every 100 feet by means of the alternative (or
similar) approach used by Parametrix in 2006 (Parametrix 2008).
Each Transect will extend approximate 600 feet from the shoreline to
approximately 10 feet Mean Lower Low Water (MLLW).
Approximately 300 fee of each transect will be surveyed by foot (intertidal area)
and 300 feet by diving (subtidal area).
Two staff will be required to perform the habitat survey by foot on the intertidal
area.
Deliverables
Two divers and one boat operator will be required for the underwater portion of the
habitat survey.
The underwater portion of the fieldwork will be performed in 4 consecutive days
(during high tide conditions).
Up to 20 dive hours will be needed to complete the habitat survey.
Cost associated with the underwater habitat survey will include a boat operator and
two divers, as required by law (WAC 296 37, Standards for commercial diving
operations).
Cost associated with this task will include time to prepare for the habitat survey
and to travel to and from the survey site. The cost also includes per deim,
lodging, equipment, and travel expenses (mileage and ferry tolls).
There are no deliverables associated with this subtask. Findings and habitat
survey data will be presented and discussed in the technical memorandum to be
prepared under subtask 3.3 of this scope of work.
Subtask 3.2 Data Analysis
Analyze the macro algae habitat survey data collected. This analysis will include a comparison
of the 2006 baseline habitat survey results obtained by Parametrix, the 2010 survey performed by
Professional Services Agreement, Page 8 2/24/2012
SW08 -01, Amendment No. 3
Herrera and with the results of the habitat survey to be performed in 2012. In addition,
compare past transect data, to be provided by the City, to evaluate whether any site erosion
may have affected macro algae habitat.
Assumptions
Past transect data will be provided by the City.
Deliverables
There are no deliverables associated with this subtask. Data analysis results will
be presented and discusse.d in the technical memorandum to be prepared under
subtask 3.3 of this scope of work.
SubTask 33 Technical Memorandum Preparation
Prepare a technical memorandum to summarize the results of the macro algae habitat survey to
be performed under subtask 3.1 as well as the results of the data analysis to be performed under
subtask 3.2. The technical memorandum will include a site map indicating the qualitative
distribution of eelgrass (if any) and macro algae species, substrate characterization, and
approximate depth contours. It is expected that the contour data will be provided by the City.
Assumptions
Contour data will be provided by the City.
There will only be on round of review on the technical memorandum and
comments will be consolidated.
Deliverables
Draft and final technical memorandum submitted in a PDF format.
