Description
Biogas generated at King County’s three regional wastewater treatment facilities and at the Cedar Hills Regional Landfill can be used as a low GHG fuel source. To support strategic decision making, King County will evaluate the economics and environmental benefits of consuming County produced biogas and RNG in County facilities until natural gas is eliminated at all County facilities. Such analysis will consider County-produced RNG as a bridge fuel to decarbonizing facility heating systems for when natural gas use cannot economically or feasibly be eliminated.
In addition to considering the benefits and costs to County operations, such analysis shall consider the benefits and potential for increased revenue to the SWD and WTD of the County’s biogas resources sold to other sectors of the economy, as is currently the case with a significant volume of the available gas. The analysis will also assess how County-produced RNG could drive actions to eliminate fossil-fueled equipment, and the global GHG impacts of County use versus uses in other economic sectors.
