Solid Waste Engineering Services - Key Personnel

JEFF DOBROWOLSKI, PE INTERIM NATIONAL WASTE SECTOR LEAD Jeff has more than 37 years of comprehensive environmental engineering, civil engineering, solid waste facility permitting and design, gas management, water supply management, and site investigation and remediation experience. He provides CM and CQA testing oversight for numerous solid waste facility construction projects. Jeff has consistently achieved regulatory approval for alternate solid waste facility system designs and mitigation measures to achieve and maintain adequate groundwater desperation. PROJECT EXPERIENCE Kern County Waste Management Department, Lebec Landfill, Lebec, California: Project manager for the preparation of final closure and post-closure maintenance plans, closure construction documents, and CQA services for closure of the Lebec Landfill. Jeff directed an alternative final cover feasibility study to evaluate the technical and economic feasibility of alternative final cover designs, which could provide equivalent or superior performance compared to the California Title 27 prescriptive (i.e., low-permeability soil) final cover. U.S. Army, Los Alamitos Joint Forces Training Base; Western Riverside County, California: Design manager for developing construction drawings, technical specifications and a CQA plan for a new waste management unit to reconsolidate excavated waste from on-site waste trenches. Jeff managed the design of an alternative composite liner system including a solar-powered leachate collection system, a passive LFG management system, soil stockpile management and grading plans, hydrologic analyses and surface water management system design, detailed grading and fill plans, and an alternative evapotranspirative (ET) final soil cover system for the waste consolidation cell. Republic Services, Sunshine Canyon City Landfill, Los Angeles, California: Project manager for the preparation of final closure and post closure maintenance plans (FCPCMPs) for the Sunshine Canyon City Landfill. Jeff directed the preparation of the FCPCMPs addenda, which included responses to regulatory agency comments, a revised alternative final cover design, an alternative final cover performance monitoring plan, a hydrologic evaluation, and upgraded design of the surface water management system. Operating Industries, Inc./New Cure, Inc., North Parcel Landfill, Monterey Park, California: Design manager for a design-build closure project for a Superfund site. The project involved removal of approximately 16,000 cubic yards of waste adjacent to I-60 and reconsolidation on the top deck area of the North Parcel Landfill. A comprehensive surface water management system was constructed to accommodate landfill slopes as steep as 1.5H:1V. Closure was achieved using a geomembrane-backed geosynthetic clay liner, an ET soil cover, and a low permeability barrier layer cover in specific areas of the site. An extensive gas, leachate, and gas condensate conveyance system had to be designed during construction, and construction permits were expedited with the California Department of Transportation (Caltrans) to facilitate the work.
