The New England Revolution is one step closer to building a stadium in Everett after the state Senate approved a bill containing details that would open a pathway to construction.

Tucked in the enormous $2.6-billion economic development bill, which senators unanimously approved, 40-0, just before midnight Thursday, is language that would remove the targeted 43-acre parcel along the Mystic River as a Designated Port Area.

The designation has restricted officials from cleaning up a “power plant site that has been a health and environmental hazard for decades,” said Sen. Sal DiDomenico, who brought the language forward as a standalone bill before it was clumped into its current package.

Under DPA status, the land at 173 Alford St is restricted to maritime purposes. If the community opposes the vision for the site, the designation would be reinstated.

“This language will allow the public process to move forward on a project that will be an economic catalyst and environmental win for our residents,” DiDomenico said in a statement Friday. “This will open up the possibility for hundreds of millions of dollars in private investment, cleanup of a hazardous waste site, create good-paying union jobs, and open our waterfront for the public to enjoy.”

For the stadium to become a reality, the concept, which has come up short in previous legislative sessions, still has to garner more approvals.

It will head to the Conference Committee as three members from the House and Senate look to settle on a compromise version of the bill by the session’s end, July 31. If agreed on, the language will be up for final votes in each chamber before it potentially makes its way for signature from Gov. Maura Healey.

The House’s economic development legislation, passed in June, did not include stadium-related language.

The proposal backed by Revolution owner Robert Kraft could bring congestion and heavy foot traffic to areas of Boston directly across the Mystic River from the potential site, Boston electeds said in April.

Boston Chief of Planning Arthur Jemison has suggested Charlestown and surrounding neighborhoods “will bear the brunt” of the transportation impacts as the MBTA’s Sullivan Square stop is the nearest public transit option.

Everett Mayor Carlo DeMaria and other officials from his city have said they’d look to invest in “the critical expansion of public transit” if the $600-million,  25,000-seat stadium proposal goes in their favor.

The Revs have played in Foxboro since their inception in 1996, at Foxboro Stadium and its current residence, Gillette Stadium, also home to the Patriots.

“We now have the opportunity to entertain a proposal for the construction of a 25,000-seat, state-of-the-art stadium surrounded by beautiful parks and green spaces for city residents and the public to enjoy,” DeMaria said in a Friday statement.
