At the Federal level, GHG emission reporting has become part of the standard regulatory requirements; however, on the west coast, GHG programs continue to develop and evolve from reporting to reduction programs beyond federal requirements. Solid waste facilities can be impacted by all of these reporting mechanisms directly as a landfill located in the state in question, opting in for C&T as part of the LCFS in California, or in limbo, as the courts work out the legality of Washington’s Clean Air Act. More stringent federal GHG requirements are unlikely with the current administration, however, that could change with the 2020 election. In general, GHG rules and legislation keep developing and updating to account for and reduce GHG emissions.
Cassandra Drotman Farrant is Project Manager with SCS Engineers. She has nine years of experience in environmental consulting, specializing in environmental assessment and greenhouse gas (GHG) verification. Cassandra has participated in many GHG verification projects throughout the U.S. and has completed approximately 70 Phase I Environmental Assessments (ESAs) in California, Oregon, and Washington. Phase I projects included research and review of geologic and hydrogeologic conditions at project sites and in the surrounding areas and evaluating the potential for soil and groundwater contamination from on and offsite sources. Cassandra has completed emissions estimates and inventories and has prepared numerous permit-to-construct/operate permit applications. She prepares compliance reports, which includes reviewing and maintaining records and regulatory deadlines.

In August 2019, SCS Energy broke ground on construction of a 4,000-scfm landfill gas to renewable natural gas (RNG) plant in Indianapolis. Indy High Btu, LLC engaged SCS Energy to build the RNG plant under an engineer/procure/construct (EPC) agreement. Indy High Btu, LLC is jointly owned by Kinetrex Energy, Southside Landfill, and EDL Energy.
The RNG plant employs an iron redox scrubber for hydrogen sulfide removal, membranes for carbon dioxide removal and pressure swing adsorption for nitrogen removal. The plant is on schedule to achieve commercial operation in February 2020.
Kinetrex, as a major distributor of LNG, intends to convert the RNG into LNG. RNG from the plant will fuel trucks replacing nearly 8 million gallons of diesel a year. RNG is less expensive than diesel and significantly reduces the emission of methane and other greenhouse gases.
The Indy High Btu RNG plant is the third landfill gas-to-RNG plant designed by SCS to employ nitrogen removal, meeting pipeline specifications and maximizing gas recovery. Two other plants, including a 5,000-scfm project in Kentucky, which commenced operation in March 2018, and a 5,000-scfm project in Texas, which is currently under construction and scheduled to begin operations in November 2019, are both SCS Energy designs.
