Innovative Pathway Regulatory Engagement

Dane County Landfill  |  Dane County, Wisconsin


Located in the heart of America’s Midwest, Dane County (Madison, Wisconsin) has always led by example when it comes to climate change action and sustainable development. Its journey toward sustainability reached a new milestone in 2016. The County launched an ambitious landfill gas upgrading plan to produce pipeline-quality renewable natural gas (RNG) for injection into a nearby natural gas utility. The concept of a shared RNG injection point or an RNG offloading station was the first of its kind in the nation. This revolutionary concept reduced the barriers for biogas producers to gain access to the pipeline, renewable energy markets, and the USEPA- and state-issued renewable fuel credits.

The County hired EcoEngineers to guide them through the intricacies (and potential pitfalls) of taking their landfill gas to pipeline-quality, building an offloading station, and monetizing the carbon reduction when the RNG is substituted for diesel fuel. EcoEngineers is still retained by Dane County in a variety of capacities.

Key Performance

  • Led a multi-day training session for county officials – educating them on current clean fuels policy and reviewing pro formas
  • Assisted county staff through the technology selection process by reviewing technology specifications and interviewing bidders
  • Guided the offtake selection process by reviewing term sheets and interviewing bidders
  • Trained staff on best practices to fulfill compliance expectations under the U.S. Renewable Fuel Standard (RFS)
  • Provided a quality assurance program to verify the carbon reduction claim

Key Results

  • Engaged with the USEPA to obtain a rule interpretation that allowed the offloading station to operate
  • Registered the project in record time under the RFS, zeroing out any projected impact on year-1 revenues from regulatory delays
