On May 15, 2017, the Federal Energy Regulatory Commission (“FERC”) granted Algonquin Gas Transmission, LLC (“AGT”) authority under FERC Docket No. CP17-438-000 to replace a portion of its existing pipeline in Somerville, Arlington and Medford. Over the last several months, you may have noticed AGT performing various survey activities within the existing pipeline corridor in conjunction with its Mystic River Crossing Replacement Project (the “Project”).
AGT’s existing pipeline which will be replaced travels under the Mystic River, but the Project will utilize the horizontal directional drilling (“HDD”) technique so as not to impact the Mystic River. AGT would like to inform you that it began pre-construction activities related to the Project on August 28, 2017. Those activities will consist of site preparation, grading, and clearing. AGT expects construction to commence in September and continue into November. During that time, AGT will place construction equipment on land adjacent to Boston Avenue in Somerville near the Somerville/Medford line and on a parcel of land at the intersection of the Mystic Valley Parkway and Decatur Street/Arizona Terrace in Arlington to support the HDD operation. Some limited traffic restrictions will also be in-place in those immediate areas.
If you have any questions during construction, AGT has set up a 24-hour, toll-free Construction Hotline at (888) 331-6553.
