Guidance Documents for Introducing Dairy, Landfill and Wastewater Biomethane into Pipelines
In 2007, GTI joined an industry-wide effort to establish renewable gas as a fungible zero-carbon product. At that time, GTI launched an initiative designed to establish parameters for evaluating the suitability of a biomethane product from nontraditional sources for introduction into existing natural gas pipelines.
Since then, GTI research projects sponsored by the natural gas industry and the U.S. Department of Transportation (DOT) have been adding to our industry's understanding of the chemical and biological composition of renewable gas derived from a wide range of sources, including dairy waste, landfill, and wastewater treatment sludge.
In 2009, under the sponsorship of a consortium of gas companies, including Operations Technology Development (OTD)—and working with a number of universities and dairy farms in the Northwest, Midwest, and Western U.S.—GTI scientists developed the first national biogas guidance document for introducing methane from dairy waste into existing pipelines.

In 2012, the GTI team developed a Landfill Guidance Document, providing analytical and other key information to pipeline companies and natural gas local distribution companies (LDCs) so that parameters specific to clean biomethane derived from landfill biomass can be identified to support a productive discussion between the biomethane supplier and the gas utility company.
The Guidance Document includes a list of constituents and methodology for testing, as well as statistical analysis of the acquired data. The Document provides data for the development of contracts for landfill-derived renewable gas, specific instrumentation for identifying and monitoring trace constituents, and cleanup technologies for removing them.
