UWMRC Proposal

• Objective - monitor and evaluate moisture
  movement and moisture balance in a bioreactor
  landfill
• Procure and install innovative instrumentation to
  monitor in situ moisture content
• Intensive monitoring period
• Develop a moisture balance within parallel
  aerobic and anaerobic cells

19
Volusia County

• Site engineers have recommended bioreactor
  operation at the Volusia County landfill.
• Unique opportunities because of shredding
  operation and double-composite liner.
• Pressure transducer installation is planned.

20
Current Schedule

• Schedule is being dictated by two factors
• 1. The Permit
• 2. Filling of Cell 3 at NRRL

21
Response to RAI3

• DEP Issued an RAI3
• Involved some minor issues as well as a few
  additional changes to the operations plan
• Operation plan changes included assurance of
  daily monitoring of some parameters

22
Response to Paul Stills Comments

• Schedule
• GPS System
• UF Lab Equipment
• Installation of Additional Pressure Transducers

GPS

• Purpose Provide an accurate, efficient, and
  rapid means to monitor surface elevations for
  settlement analysis and equipment installation.

Installation of Pressure Transducers

• The project team made a decision that the value
  gained by the installation of additional pressure
  transducers was worth the cost.
