other technical information will be provided in the format and quantities necessary to support each application. The County will review and approve all submittals prior to submission. In coordination with the County, services will include attendance at meetings, consultations with permitting agencies, responding to comments, and preparation of revisions to application information and documentation as requested by the agencies and authorities and as directed by the County. LPL Permit Based on regulatory feedback from Task 1 and approval from the County, the Consultant will progress the preliminary expanded LPL concept figure to the Site Plan which will be the basis for updating the LPL permit application. The Consultant will use the 2004 LPL permit application as a template for the application update, revising information where required based on the proposed expansion, County identified operational changes, and regulatory input. The updated LPL application will be prepared in accordance with the requirements of WAC 173-350- 400, and include engineering drawings, calculations, and reports. The Consultant will update the geotechnical and hydrogeologic elements and reports within the application to account for the expansion and support a proposed continuation of operation without an engineered liner. The expanded waste footprint is expected to require the installation of up to two new groundwater monitoring wells. Well locations will be discussed with regulators as part of Task 1, with installation as part of Task 2. Some key elements of the LPL permit update will include revisions to the following documents: • Engineering Report to maximize the available footprint of the waste disposal area and facility capacity, and continued operation without an engineered liner. • Plan of Operation to establish accepted waste types that will meet the County's needs. • Closure Plan to continue to utilize a facility -specific final cover consistent with that previously approved which will be installed incrementally as landfill areas achieve final fill configuration, thus reducing the financial assurance requirements that would otherwise pertain to the entire facility closure at one time. • Post -Closure Plan. Significant modifications to the LPL application materials are expected to include: • Site plan • Landfill life capacity and analysis, including financial assurance analysis • Site development plan • Site final fill plan • Site cross sections • Stormwater management design and calculations Professional Services Agreement (rev. 09/24/2018) Page 15 of 23
