Public hearing and comment critical to protect environment
New Haven, CT — Save the Sound is pleased by the announcement Friday that the Connecticut Department of Energy and Environmental Protection has opened a new public comment period on Iroquois Gas Transmission System, L.P.’s proposed expansion of its Brookfield Compressor Station. Save the Sound is also pleased that DEEP has proposed adding air monitoring requirements for the Brookfield compressor station. However, Save the Sound is concerned that DEEP is also revising carbon monoxide emissions limits in a way that increases, rather than decreases, the impact to public health.
The new comment period allows Save the Sound and any other concerned residents to petition for an adjudicatory hearing challenging the permit.
Save the Sound first petitioned for an adjudicatory hearing more than ten months ago under the previous notice. Read more about the project and Save the Sound’s concerns in the September 17, 2025 press release.
“We’re encouraged that the Governor and DEEP have indicated they will require air quality monitoring,” said Jessica Roberts, Connecticut staff attorney at Save the Sound. “But the state of Connecticut can’t protect its residents, keep its air clean, and meet its greenhouse gas reduction obligations if it keeps allowing expansions of gas infrastructure without appropriate safeguards.”
In a formal response issued Friday afternoon, DEEP replied to previous public comments. This response to comments will be available on DEEP’s Adjudications website shortly as an attachment to the Hearing Officer Report for this matter. In addition, DEEP provided revised draft permits, which require Continuous Emissions Monitoring Systems for nitrogen oxides at the site and raise the emissions limit for carbon monoxide.
“Requiring more consistent and advanced air quality monitoring is a critical step for transparency and public health, but we remain deeply concerned about this project’s impacts, including its carbon monoxide emissions,” said Roberts. “Brookfield already has elevated levels of ozone, which worsens asthma and bronchitis and can damage airways. Expanding the Brookfield Compressor Station to supply gas to New York needlessly burdens Connecticut residents, degrading their air quality and threatening their health and safety.”
DEEP’s notice of the 30-day public comment period can be viewed here. This notice also contains links to the revised draft permits for Iroquois. Save the Sound encourages all concerned Connecticut residents to look for more information and to submit comments.
