Natural Gas: Frequently Asked Questions

Where is the Iroquois pipeline?

The Iroquois pipeline is a 416-mile interstate natural gas pipeline system that begins at the TransCanada interconnect in Iroquois, Ontario, Canada and extends from the U.S. Canadian border at Waddington, NY, through New York State and western Connecticut to Commack, NY; and from Huntington, NY to its terminus in Hunts Point in Bronx, NY.

Where is Iroquois headquartered?

Iroquois Pipeline Operating Company, the agent for and operator of the pipeline, is headquartered in Shelton, CT.

Are pipelines safe?

Natural gas pipelines are the nation's safest method of transporting energy, quietly delivering large volumes of the clean-burning fuel to various shippers, power plants and local gas distribution companies, who ultimately carry the gas to homes and businesses. While accidents are rare, they are usually the result of outside forces or unauthorized action by someone other than a pipeline company.

What other pipelines interconnect with Iroquois?

Waddington, NY = TransCanada Pipelines

Canajoharie, NY = Dominion Transmission
Wright, NY = Tennessee Gas Pipeline
Brookfield, CT = Algonquin Gas Transmission
Shelton, CT = Tennessee Gas Pipeline

Does Iroquois sell gas?

No, Iroquois is only a transporter of natural gas.

Does natural gas explode?

Natural gas is lighter than air and as such rises freely when not obstructed. Natural gas is flammable only in concentrations of 5% to 15% gas in air and can be explosive if contained in a confined space.

Who is responsible for approving natural gas pipeline projects proposed by Iroquois?

Iroquois is required to comply with the regulations of the Federal Energy Regulatory Commission (FERC) and other appropriate federal, state and local agencies. The FERC, as lead federal agency, will make an assessment of the project from an environmental standpoint and will issue a determination of whether or not the proposed project is within the public convenience and necessity. Additional information on the FERC process can be found at www.ferc.gov.

What pipeline standards, codes, rules, laws, restrictions, regulations, and controls govern pipeline installation and maintenance?

The primary governing code for the design, construction, operation and maintenance of pipeline facilities is the U.S. Department of Transportation (DOT), Title 49 Code of Federal Regulations (CFR), Part 192; Transportation of Natural Gas and Other Gas by Pipeline: Minimum Federal Safety Standards. This safety regulation will be used in conjunction with many other supplemental codes and standards to ensure a safe and reliable pipeline system.

Does Iroquois have storage directly connected to its pipeline?

No - however, Iroquois is able to offer "storage-like" products using our PAL service. For further information regarding the types of transportation services Iroquois offers, please visit Pipeline Services.

Is there a difference between propane and natural gas?

The difference between propane and natural gas comes down to their portability, compression, energy efficiency, and cost.  A difference in the physical properties of propane and natural gas is how easily they liquefy and transport. Propane turns into a liquid at -46°F (-43°C), so it's easy to compress and carry in a portable tank. You can buy compressed propane at most gas stations. It's decompressed by a valve at the source of use, such as a barbeque grill. Natural gas does not compress as easily. It usually comes to your home from a utility company along dedicated lines to power things like a central heating system,clothes dryer, and water heater. Propane is heavier than air whereas natural gas is lighter than air. Both natural gas and propane will dissipate into the air if they are released in an open enough environment and both can pose an explosive risk if they are concentrated enough and are ignited. However, since propane is heavier, it tends to fall to the ground, collect, and pose a greater explosive risk. On the other hand, because natural gas is lighter than air, it tends to rise and dissipate into the air, posing less of an explosive risk.
