<br />COMBINED SEWER CONVEYANCE PROJECT – SCOPE OF WORK CATEGORY 2 – FOR OFFICIAL USE ONLY / DISCLOSURE PERMISSIBLE BY LAW 5 <br />exploration locations and other pertinent features, summary boring logs, and laboratory test <br />results. The report will provide geotechnical recommendations for design and construction of the <br />proposed improvements including parameters for Contractor’s design of temporary shoring and <br />dewatering systems. <br />Task 200 Assumptions <br />1. Field explorations will not require traffic control or environmental permits. <br />2. Groundwater monitoring piezometers will not be installed as groundwater is anticipated to be <br />shallow, about the same elevation as the water bodies near the proposed pipeline alignment. <br />3. Piles will be required to support the proposed structures and pipes. <br />4. Site reconnaissance is limited to observation of existing topography and features; no excavation or <br />subsurface exploration will be conducted during site reconnaissance. <br />5. Exploration locations will be accessible by truck- or track-mounted rigs. <br />6. The geotechnical explorations proposed herein will not be used to assess site environmental <br />conditions. However, visual or olfactory observations regarding potential contamination will be noted. <br />Analysis, testing, storage, and handling of potentially contaminated soil and groundwater (either <br />sampled or spoils) are beyond this scope of services. If contaminated soils and/or groundwater <br />appear to be encountered, the material will be properly contained on-site for evaluation and disposal. <br />Costs incurred for environmental services beyond on-site containment would be in addition to this <br />scope and budget. <br />7. Coring or restoration of asphalt or concrete pavement will not be required prior to drilling the <br />proposed explorations. <br />8. Phase 1 or Phase 2 Environmental Site Assessments are not required. <br />9. Seismic and site specific probabilistic seismic hazard analysis (PSHA) are not required. <br />Task 200 Meetings <br />1. Attendance at Project Kick-Off Meeting. <br />2. Site Reconnaissance Meeting. <br />3. Attendance by HWA/GeoSciences at up to six project coordination meetings via video or tele <br />conference. <br />Task 200 Deliverables <br />1. Field Exploration Work Plan Memoranda. <br />2. Geotechnical Engineering Report. <br />TASK 300 – ENVIRONMENTAL PERMITTING SERVICES <br />The purpose of this task is to identify and assist with the environmental documentation and permitting <br />needs associated with the project. A State Environmental Policy Act (SEPA) Environmental Checklist will be <br />prepared and services performed to secure permits and reviews for the project under Section 404 of the <br />Clean Water Act, including US Army Corps of Engineers permit under Nationwide Permit 12 for utility line <br />activities, water quality certification by the Washington State Department of Ecology (Ecology) under <br />Section 401 of the Clean Water Act, and Ecology review for consistency under the state Coastal
