Project Description:

The Eastern System Upgrade Project is proposed by Millennium Pipeline Company, LLC (Millennium) and includes the construction of a new 30- and 36-inch-diameter pipeline looping along Millennium's existing mainline right-of-way in Orange County (Huguenot Loop), a new compressor station (Highland Compressor Station) and an upgrade to an existing compressor station (Hancock Compressor Station). The Project would provide approximately 223,000 dekatherms per day (Dth/d) of firm transportation service from Millennium's existing Corning Compressor Station to an interconnect with Algonquin Gas Transmission, LLC in Ramapo, New York. 91 percent of the Project capacity is subscribed under long-term, firm contracts with local distribution companies and municipalities. All of the proposed pipeline loop would be co-located along the existing Millennium Pipeline ROW.

The Eastern System Upgrade Project will include the crossing of 14 streams, including eight perennial streams and six intermittent streams. Seven of the streams have a classification of C(t) or higher (protected streams) and seven intermittent or ephemeral streams flow into protected streams. Seven stream crossings will be conducted using a horizontal directional drill (HDD) or Direct Bore (DP) method and seven streams will be crossed using the dry crossing method (i.e., dry waterbody, dam and pump or flume). Of the seven streams traversed by a dry crossing method, one of the streams is a Class C(ts) and one of the streams is a Class C(t). The remaining five streams crossed by a dry crossing method are not protected pursuant to Article 15 Protection of Waters. The access road for the Highland Compressor Station will cross one additional stream using an open-bottom box culvert.

The Eastern System Upgrade Project will also include the crossing of two New York State Department of Environmental Conservation (NYS DEC) Regulated (or eligible) Freshwater Wetlands via open-trench totaling 35 foot in length with 0.6 acres of permanent forest conversion impact located within the 50-foot ROW. There will be no permanent fill in wetlands.

Millennium filed an application for a Certificate of Public Convenience and Necessity (Certificate) with the Federal Energy Regulatory Commission (FERC) on August 25, 2016 to construct and operate the Eastern System Upgrade Project. FERC is the lead agency for the environmental review of interstate natural gas pipelines. On March 31, 2017, FERC staff prepared an Environmental Assessment (EA) for the Eastern System Upgrade Project proposed in Docket No. CP16-486, in accordance with the requirements of the National Environmental Policy Act (NEPA).

NYS DEC relies upon the federal NEPA environmental impact review process conducted by FERC to complete its review of the permit applications submitted by applicants to NYS DEC and to ultimately make a determination whether to issue its authorizations. In accordance with Section 401 of the Clean Water Act (CWA), applicants seeking a federal license or permit for activities that may result in a discharge to federally regulated waters must obtain a Water Quality Certification (WQC) from NYS DEC indicating that the proposed activity will comply with State water quality standards. The review and issuance of a WQC will also include approvals pursuant to Environmental Conservation Law (ECL) Article 15, Protection of Waters and Article 24, Freshwater Wetlands.
