The staff of the Federal Energy Regulatory Commission has issued a draft supplemental environmental impact statement (SEIS) for the Southeast Market Pipelines Project to address the August 22, 2017 Opinion issued by the United States Court of Appeals for the District of Columbia regarding the Commission’s environmental review of the Southeast Market Pipelines Project.
According to the statement, constructing and operating the Southeast Market Pipelines Project would result in temporary and permanent impacts on the environment. However, with the applicants’ implementation of their respective impact avoidance, minimization, and mitigation measures, as well as their adherence to the measures we have required to further avoid, minimize, and mitigate these impacts, operating the Southeast Market Pipelines Project would not result in a significant impact on the environment.
The Southeast Market Pipelines Project is composed of three separate, but related, interstate natural gas transmission pipeline projects. These projects are: Transcontinental Gas Pipe Line Company, LLC’s Hillabee Expansion Project, Sabal Trail Transmission, LLC’s Sabal Trail Project and Florida Southeast Connection, LLC’s Florida Southeast Connection Project. Together, these projects involve the construction and operation of approximately 685 miles of pipeline and associated facilities.
The draft SEIS incorporates by reference and expands upon the analysis contained within the December 2015 final environmental impact statement (FEIS) for the Southeast Market Pipelines Project. The draft SEIS estimates the greenhouse gas emissions generated by the Southeast Market Pipelines Project’s customers’ downstream facilities, describes the methodology used to determine these estimates, discusses context for understanding the magnitude of these emissions, and addresses the value of using the social cost of carbon tool.
