Greenhouse emissions could soon be converted to renewable natural gas that gave Contra Costa County the opportunity to build a new processing plant and underground pipeline at the Keller Canyon landfill in Pittsburgh.
The Board of Supervisors this week unanimously approved Amerasco’s revised land use permits, environmental documents, negatively declared research survey, saying the removal of the project would not have a significant impact on the environment.
Massachusetts-based Amersco already operates a gas-to-power power plant at Landfill, which produces the fuel used to light internal combustion generators to generate electricity through filtration and drying. Excess gas is then destroyed in the nearby enclosed combustion facility.
Under the plans, the new renewable natural processing facility, located almost entirely in the landfill, will use this excess gas and operate the existing gas plant independently.
In a presentation to the board, Stan Muroka, the county’s senior planner, said: “This will significantly increase the use of the now-destroyed landfill gas and energy.
Jim Bear, a senior project developer at Ameresco, explained that the gas that is now emitted in landfills is wasted and goes straight into the atmosphere.
“So, what Amersco is going to do is take the waste energy and process it into renewable natural gas that can be used to displace fossil fuels in vehicles,” he said. “Thus, this project has not only provided tremendous financial benefits to the counties, but also environmental benefits should not be overlooked.”
He said renewable natural gas from the new 48,000-square-foot processing facility would then travel 2.75 miles of pipeline for a connection to the existing PG&E natural gas transmission pipeline, located on the PG&E property before land.
Earlier, some objected to the plan, but Pittsburgh’s director of environmental affairs, Laura Wright, said there was not enough time to revise the 7866-page document and make new ones. The builders of the discovery, which planned to develop the nearby Stoneman Park property, where the city’s golf course once stood, wanted more time.
In response to comments from Pittsburgh and others, Muroka said the proposed pipelines had been amended in three parts, removing 5 percent of the proposed pipeline to be placed within the PG&E property and an additional 25 feet east of the boundary. With the proposed Stoneman Park development. The company has modified the route to better differentiate it from existing and future underground utilities.
“The proposed project has been modified to minimize any potential impact on the city of Pittsburgh or to develop the Stoneman Park property in the future,” Muroka said.
As part of the oversight, according to Supervisor Federal Glover, America must sign a Community Benefit Agreement, which includes district landfills. The deal would include paying ক 50,000 a year to the Keller Canyon Mitigation Fund to distribute to the community.
The question about the project was Bob Doyle, who wanted to know about the impact on local housing.
The region is part of the East Contra Coaster Habitat Conservation and, as such, Ameresco will have to work with nonprofits on any biological issues related to the pipeline, Muroka said, adding that the agreement will be made later and finalized.
