Joint Comments on the Midcontinent Supply Header Interstate Pipeline

April 6, 2018

We recently submitted joint comments with EDF and Sierra Club to the Federal Energy Regulatory Commission on the draft environmental impact statement (DEIS) for the Midcontinent Supply Header Interstate Pipeline. The analysis covers a proposal to construct over 200 miles of pipeline, as well as compressor stations, a booster station, and accompanying facilities, to transport natural gas. The DEIS quantifies the tons of downstream greenhouse gas emissions related to this project—over 28 million metric tons of carbon dioxide per year—but FERC fails to use the social cost of greenhouse gases metric to fully account for the climate effects of these emissions. FERC’s failure to adequately consider climate damages from the pipelines it approves is under increasing scrutiny. Our comments offer a detailed rejection of FERC’s rationale for excluding the social cost of greenhouse gases from this analysis, and give FERC additional guidance on how to monetize climate effects consistent with the currently best available science and economics.
