Downeast LNG received local approvals from the town of Robbinston in the spring of 2006. In December of that year, the company filed for Federal Energy Regulatory Commission (FERC) and other federal permits.

In May 2009 FERC issued a Draft Environmental Impact Statement (DEIS), along with the draft Waterway Suitability Report (WSR) and Letter of Recommendation from the U.S. Coast Guard for its proposed import project. In May 2014, the Federal Energy Regulatory Commission issued the Final Environmental Impact Statement for the originally planned import project.

Downeast LNG filed its amended application as a bi-directional facility with the FERC in July of 2014 and its request to export LNG with the DOE in August of 2014. Downeast has received authorization to export 3.5 million tons of LNG to FTA countries and its non-FTA application request is pending.

Downeast LNG expects to file all of its Resource Reports with FERC in spring 2015, with a full FERC filing in the summer of 2015. After FERC files its supplemental Final Environmental Impact Statement for the bi-directional facility, Downeast LNG will file its state permit applications.

Downeast LNG expects to receive FERC authorization to construct at the end of 2016 or early 2017. Construction is expected to begin by the end of 2017, with completion by the end of 2020.
