Iroquois Operations and Sustainability

We are committed to doing our part to protect the environment. This commitment includes reducing our operation's greenhouse gas emissions and looking for ways to partner with renewable energy sources, all while continuing to transport clean and efficient natural gas.

 

STAR Partner Best Management Practices and Greenhouse Gas Reporting

Natural Gas EPA Pollution PreventerIroquois has been a member of the U.S. Environmental Protection Agency's (EPA) Natural Gas STAR program since 1996. STAR is a voluntary government/industry partnership designed by the EPA to accomplish environmental protection through cost-effective measures. Launched in 1993, the program encourages natural gas companies to adopt "Best Management Practices" that can reduce emissions of natural gas.

Under this program, Iroquois Gas Transmission System's methane reduction measures include the following actions:

  • Direct inspection at meter stations, valve sites and compressor stations.
  • The installation of turbines with electric starters instead of using reciprocating engines.
  • Installing low, no-bleed pneumatic devices to regulate gas flow and pressure.
  • The use of isolation valves, which allow blowdowns on sections of the compressor station instead of the entire station.
  • Venting of the pipeline inspection gauge receiver into fuel that is used to power equipment, instead of releasing it into the atmosphere.
  • Reducing pressure before conducting blowdowns, which decreases the amount of gas that is released into the atmosphere.
  • Using hot tap method during a valve installation, which allows for the remaining section of pipe to be left in service.

The company continually looks for ways to reduce methane emissions through our operations. As part of the STAR Program, Iroquois annually submits a report that documents our voluntary emission reduction activities and as a member of the Interstate Natural Gas Association of America (INGAA), the compay has committed to the completion of methane surveys of all its compressor stations by 2022.

In addition to the measures achieved through the STAR Program, Iroquois has already modified its maintenance practices to reduce the amount of natural gas vented in the course of routine operations.

Iroquois Joins U.S. Environmental Protection Agency Methane Challenge Program

Methane Challenge U.S. EPATo further its commitment to reduce environmental impacts from its operations, Iroquois Gas Transmission System has signed a partnership agreement with the U.S. Environmental Protection Agency (EPA) under the agency's voluntary Methane Challenge Program.

Through this agreement, the company will reduce pipeline venting between compressor stations (including venting at tie-ins and meter stations, and through maintenance activities) by at least 50% by 2025. Iroquois will submit a formal implementation plan to the EPA by the end of August 2020 and will begin reporting its progress towards its commitment in 2022.

Utilization of 100% Green Energy at Iroquois' New York and Connecticut Facilities

Iroquois is committed to running its business in the most efficient and environmentally conscious way possible. As part of this promise, we have secured a contract with Constellation NewEnergy, Inc. for electricity rates at each of our Connecticut and New York facilities utilizing 100% green energy.

The green energy will come from wind power that is generated across the U.S. for our 46 New York-based accounts beginning in January 2020, and for our 29 Connecticut-based accounts beginning in November 2020.

Our decision to have our electric supply come from a green energy source reflects our sense of great responsibility to do our part to protect the environment, while also knowing that this renewable energy is a sustainable, accessible and affordable option for our business.
