Challenges to Successfully Manage Airspace

Airspace management is one of the most significant challenges faced by today’s landfill owners and operators. Airspace represents the essential source of revenue for the landfill owner/operator and payment for its use, collected through gate/tipping fees, should cover all of the obligations associated with the facility. Therefore, developing, using, and caring for it is of utmost importance.

Following this presentation, participants will be able to:

  • Maximize the size of the fillable waste envelope
  • Optimize day to day operation
  • Minimize capital expenditures and potentially generate additional revenue

Dan Fellon, P.E., Vice President, Solid Waste Management, ARM Group, Inc.

Dan Fellon

Daniel Fellon is vice president of ARM’s Solid Waste Management practice. He has been involved in many solid waste management, geotechnical, and environmental engineering projects since 2005. His solid waste management experience includes landfill expansion and infrastructure permitting and construction projects, mechanically-stabilized earth (MSE) berms, solid waste relocation and beneficial reuse projects; landfill closure plans and equivalency evaluations including alternative final cover systems; compliance-related sampling, monitoring, and reporting; and construction quality assurance (CQA). Mr. Fellon directs projects with ARM’s CQA professionals and has managed projects involving landfill cell liner and closure cap installations, MSE berm construction, soil borrow and earthmoving activities, transfer stations and solid waste facility support buildings, leachate containment facility rehabilitation, and water management controls. He also has performed value engineering studies, constructability reviews, visibility and line-of-sight studies for land development and solid waste facility expansion projects, and stormwater management and E&S control sequence designs for interim and permanent stormwater management. Mr. Fellon holds professional engineering licenses in Pennsylvania, Maryland, Virginia and South Carolina, and graduated from Bucknell University with a Bachelor’s degree in civil and environmental engineering and a Bachelor’s degree in geology.

The Management and Development of Landfill Permitted Airspace: The Cost of Construction and Airspace

The business of landfills is the selling of permitted constructed airspace. It is important that the modern sanitary landfill effectively plan the construction of its permitted waste disposal footprint as the airspace that it creates is a finite commodity. Knowing when to construct waste disposal footprint and how much of it to construct is a fundamental task of landfill operations that must be carefully planned throughout the life span of the landfill such that the site is profitable. Landfill waste disposal area construction is an expensive capital expenditure and the subsequent placement of waste within its boundaries generate operational (leachate), capital (landfill gas, infrastructure), final cover closure and post-closure care costs. The means of making accurate financial estimates and planning landfill construction in terms of the overall life span as well as annual planning are typically summarized in sophisticated spreadsheets known as “work books” or “models.” The annual update of a landfill’s financial model determines the landfill construction to be completed and the estimated landfill capital and operating cost needed for a given year.
