Project Scope

  • Originated and developed the Twin Chimneys RNG project, including site feasibility and gas resource evaluation
  • Coordinated permitting and regulatory approvals with state and local agencies
  • Structured the project for pipeline injection in partnership with the local utility
  • Managed overall project execution, including schedule, budget, and contractor coordination
  • Oversaw construction of the RNG facility and integration with the landfill gas system
  • Led commissioning, startup, and performance testing of the plant
  • Currently operates the facility, including: Gas flow optimization, plant performance monitoring & environmental compliance and reporting
  • Provides ongoing maintenance and asset management for long-term reliability
  • Installed and expanded the landfill gas wellfield to support RNG production volumes
  • Drilled vertical extraction wells and installed horizontal collectors in active landfill areas
  • Constructed the gas collection piping network connecting the wellfield to the processing facility
  • Installed header lines and performed tie-ins to the RNG plant
  • Completed excavation, trenching, and grading required for gas infrastructure installation
  • Installed condensate management systems to ensure proper gas quality and flow
  • Performed wellfield balancing and tuning to optimize methane recovery
  • Coordinated construction activities with landfill operations to maintain site continuity
  • Provided ongoing wellfield maintenance and adjustments post-startup
  • Fabricated skid-mounted gas conditioning systems for moisture and contaminant removal
  • Manufactured gas upgrading equipment to refine landfill gas into high-BTU RNG
  • Built compression packages to deliver gas at pipeline injection pressure
  • Assembled modular process units to enable efficient on-site installation
  • Supplied interconnecting piping and integrated process skids
  • Conducted factory acceptance testing prior to delivery
  • Supported field installation and commissioning of all fabricated systems
  • Customized equipment design to match the specific gas composition at Twin Chimneys
  • Developed complete process and mechanical design for the RNG facility
  • Produced P&IDs, process flow diagrams, and plant layout drawings
  • Designed electrical systems and specified instrumentation for the plant
  • Engineered and programmed the PLC-based control system
  • Implemented SCADA for real-time monitoring and remote operation
  • Integrated landfill gas collection, processing equipment, and pipeline injection systems
  • Designed safety systems, alarms, and automated shutdown protocols
