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 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.
