Iroquois Pipeline

August 9, 2017

Chazen has held a term contract with Iroquois Gas Transmission System LP since 2012 to assist with wetland and ecological activities along their utility corridor stretching from the St. Lawrence River through Connecticut to Long Island.

Assignments have included delineation of streams and wetlands, reviews for endangered species, and identification of concentrations of invasive species in advance of vegetative mowing practices along rights-of-way. Chazen monitors vegetation maintenance activities to ensure compliance with timing restrictions for stream crossings, wetlands, endangered species, and to minimize the spread of invasive species.

Chazen also delineates wetlands and streams, identifies endangered species, and completes permitting for pipeline maintenance activities including installation of cathode protection, corrective stream subsidence and bank stabilization efforts. Chazen provides construction monitoring of those activities to ensure permit compliance.
