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 1 to the Professional Services Agreement SW08 -01 extends the work in support of PALF Post Closure Permit compliance through 2010. The original task descriptions are reiterated here, and a new task is added for a macro -algae survey 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 1— 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 three (3) Biannual Groundwater Monitoring Results Reports (2 Biannual 2009, 1 Biannual 2010, and 2 Biannual 2010). The City performs groundwater monitoring and creates time series plots, trilinear diagrams, stiff diagrams, potentiometric maps, and conducts statistical analyses. 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. 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. c) Comparison of groundwater quality data to groundwater standards, including Maximum Contaminant Levels (MCLs). Page 2 of 10 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. 3. Based on recommendations from the 2008 Seawall Fluid Analysis Technical Memorandum (Aspect Consulting, 2009b), it was recommended that two additional seawall fluid samples be collected using low -flow sampling techniques and analyzed for parameters summarized in Table 3 of the memorandum. An addendum to the previous memorandum (Aspect Consulting, 2009b) will be prepared, summarizing the analytical results of the additional samples, and providing any changes in recommendations for the handling of the seawall fluids. Options include continued monitoring or incorporation of the seawall fluid collection system into the leachate system. Assumptions: Exhibit A to Amendment 1— Professional Services Agreement SW08 -01 Scope of Work 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. k) The City will prepare a summary of the results of the gas system monitoring and maintenance and surface water monitoring and maintenance. The City would like the Consultant to review the reports. The report will be submitted annually, with the Annual Groundwater Report. 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. Page 3 of 10 Exhibit A to Amendment 1— Professional Services Agreement SW08 -01 Scope of Work 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.

Page 6 of 10 TASK 3 MACRO -ALGAE SURVEY Exhibit A to Amendment 1— Professional Services Agreement SW08 -01 Scope of Work A macro algae habitat survey 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, is required as part of the landfill site monitoring under the post closure permit. The survey will be performed by the Consultant or an approved subconsultant according to the Washington State Department of Fish and Wildlife (WDFW) Intermediate Eelgrass /Macro Algae Habitat Survey Guidelines. WDFW is the agency which issues the Hydraulic Project Approval Permit (HPA). This scope of work includes a discussion of the activities, assumptions, deliverables, and a schedule associated with this project: Task 3.1 Background Review and Coordination with WDFW Task 3.2 Macro Algae Habitat Survey Task 3.3 Data Analysis Task 3.4 Technical Memorandum Preparation Task 3.5 Quality Assurance /Quality Control Review Task 3.6 Project Management /Contract Administration. Task 3.1— Background Review and Coordination with WDFW The Consultant or an approved subconsultant will perform a background review of existing pertinent information in preparation for the macro algae habitat survey. This will include review of the following: 2008/2009 survey transect data on erosion of the beach as a result of the construction of the landfill revetment wall. Macro -Algae Survey prepared by Parametrix (March 2008). HPA permit (requirements pertaining to the macro algae habitat survey). In addition, the Consultant or an approved subconsultant will coordinate with WDFW before, during (if needed), and after the macro algae survey in accordance with the Intermediate Eelgrass/ Macro Algae Habitat Survey Guidelines (WDFW 2006). Deliverables: There are no deliverables associated with this task. Task 3.2 Macro Algae Habitat Survey The Consultant or an approved subconsultant will 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 2006 by Parametrix, while establishing the baseline conditions along this shoreline segment. Page 7 of 10 Exhibit A to Amendment 1— Professional Services Agreement SW08 -01 Scope of Work The macro algae 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. The location of each transect will be the same as those established during the 2006 survey performed by Parametrix. To this end, the same coordinates previously established for the origin and endpoint of each transect will be used. 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 approximately 600 feet from the shoreline to approximately -10 feet Mean Lower Low Water (MLLW). Approximately 300 feet of each transect will be surveyed by foot (intertidal area) and 300 feet by diving (subtidal area). Page 8of10 Two people will be required to perform the habitat survey by foot on the intertidal area. 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 includes a boat operator and two divers, which is required by law (WAC 296 —37, Standards for commercial diving operations). Cost associated with this task includes time to prepare for the habitat survey and to travel to and from the survey site. The cost also includes per diem, lodging, equipment, and travel expenses (mileage and ferry tolls). Deliverables There are no deliverables associated with this task. Findings and habitat survey data will be presented and discussed in the technical memorandum to be prepared under Task 3.4 of this scope of work. Task 3.3 Data Analysis Consultant or an approved subconsultant will analyze the macro algae habitat survey data collected in Task 3.2. This analysis will include a comparison of the 2006 baseline habitat survey results obtained by Parametrix with the results of the habitat survey to be performed in 2010 by Herrera. In addition, past transect data will be provided by the City, and the subconsultant will compare current conditions, to evaluate whether any site erosion may have affected macro algae habitat. Assumptions The City will provide available past transect data. Assumptions Contour data will be provided by the City. Exhibit A to Amendment 1— Professional Services Agreement SW08 -01 Scope of Work Deliverables There are no deliverables associated with this task. Data analysis results will be presented and discussed in the technical memorandum to be prepared under Task 3.4 of this scope of work. Task 3.4 Technical Memorandum Preparation A technical memorandum will be prepared to summarize the results of the macro algae habitat survey to be performed under Task 3.2 as well as the results of the data analysis to be performed under Task 3.3. 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. Page 9 of 10 There will only be one round of review on the technical memorandum and comments will be consolidated. Deliverables Draft and final technical memorandum submitted in a PDF format. Task 3.5 Quality Assurance /Quality Control Review An established system of quality assurance /quality control review will be adhered to in order to ensure high quality deliverables that comply with the requirements of the scope of work. Work products will be reviewed by a technical lead, technical editor, and ultimately by the principal -in- charge. Task 3.6 Project Management/Contract Administration The consultant is responsible for coordinating project activities and contract administration for the macro -algae survey with City- approved subconsultants, and with the City representative. Deliverables Monthly progress reports and invoices. Exhibit A to Amendment 1— Professional Services Agreement SW08 -01 Scope of Work Project Schedule The following schedule assumes that the macro algae habitat survey will be completed on one of the two specified timeframes in July or August as they are dependent on predicted tidal conditions suitable for diving. However, the schedule assumes that the survey will be performed in August in order to provide flexibility.
