RESPEC PROJECT

Conceptual design through permitting and construction of a major expansion to the landfill gas and gas-to-energy plant that provides power to the local prison, the landfill, and the public electrical grid. Project included the replacement of existing gas collection wells and the associated piping network, new Caterpillar 3520 engines, building expansion, 1.5-mile power transmission line to generate up to 6.0 MW of electricity.

Project Highlights

PLANNING & PERMITTING

• Air quality permits
• Erosion & sediment control plan
• Topographic Survey for Wellfield, Plant Area, and Utility Corridor design between the Energy Plant and adjacent user
• Wetland delineation and permitting
• Survey & Utility Easement for the power transmission line

DESIGN & CONSTRUCTION SUPPORT

• New landfill gas collection and conveyance system
• Mechanical design of gas and condensate management systems
• Civil and stormwater design of plant building expansion
• Geotechnical investigation and electrical resistivity survey for plant
• Coordination of Structural and architectural design of building expansion
• Construction plans and documents and Bid Management
• Field CQA

Benefits (Engineering, Economics, & Environment)

• State of the art controls with integration of landfill gas wellfield / collection system and LFGTE components providing a stable consistent vacuum requiring less labor for manual system adjustment.
• Maintained current operations while expanding the existing LFGTE Building.
• Additional revenue due to increased energy generation.
• Reduction of greenhouse gas emissions through additional gas collection and less flaring.
