Arc5 consulted directly to management. For new capital projects, Arc5 assumed responsibility for developing and implementing effective environmental permitting strategies. A particular strength at Arc5 was air quality expertise for energy generation. When a permitting engagement required additional specialized expertise or a broad resource base, Arc5 had the extensive professional ties nationally to arrange and manage this. Arc5 directed the environmental consultant team during the engagement, and serving on that team, provided expert environmental services for siting, permitting, impact assessment, and stakeholder engagement. For existing facilities, Arc5 furnished expert guidance on pro-active approaches for staying in environmental compliance.

The services provided by Arc5 Environmental Consulting:

  • Site selection screening and “fatal flaw” analyses
  • Fuel supply sustainability assessment
  • Site environmental evaluation (e.g., wetlands, visual impacts, fauna/flora, cultural/archaeological)
