Smoke and flames rose over storage tanks at a chemical manufacturing plant on Quincy Point overnight as emergency crews rushed to contain the blaze. Police blocked off the area surrounding Twin Rivers Technologies while firefighters worked the scene, and video from the area showed flames visible against the night sky near the facility's tanks.
The fire broke out at Twin Rivers Technologies, a chemical manufacturing plant located in Quincy, Massachusetts, according to WHDH 7News. The outlet, citing reporter Kennedy Hayes, described the story as still developing early Sunday and said no additional information was immediately available about injuries, the cause, or the extent of damage. Police had blocked off the streets around the plant as crews worked to bring the fire under control.
A Waterfront Plant With A History Of Fire and Environmental Trouble
Twin Rivers Technologies sits at 780 Washington Street on Quincy Point, where the Town River and Weymouth Fore River meet — a site originally built as a Procter & Gamble soap plant before Twin Rivers acquired it in 1994, according to background compiled on the Quincy waterfront's industrial history. The company was later acquired in 2007 by Malaysia-based FGV Holdings. This is not the plant's first brush with fire: in November 2018, emergency crews responded to a two-alarm fire at the same facility after heated oil leaked from a 1,000-gallon fractionator device and ignited, as reported by Powder & Bulk Solids. Firefighters contained that earlier blaze within two hours without any reported injuries.
The plant manufactures more than 80 commercial fatty acid and glycerin products using feedstocks like coconut oil, palm oil, soybean oil, and animal fats, per the company's own description of its oleochemical product lines. Those products supply major consumer manufacturers of soaps, foods, detergents, and cosmetics. The Quincy site is also a key North American producer of palmitic acid phase-change products used in bio-based thermal energy storage, as well as USP vegetable-grade glycerin used in pharmaceutical formulations, according to industry trend data from IndexBox.
Recent Settlement Over Water and Air Pollution
The fire comes roughly a year after Twin Rivers Technologies agreed to a $600,000 settlement with the Conservation Law Foundation to resolve a federal lawsuit alleging Clean Water Act and Clean Air Act violations. The lawsuit accused the company of discharging oil, grease, heavy metals, and volatile organic chemicals into local Quincy waterways and air, according to the Conservation Law Foundation. Under that May 2025 agreement, $300,000 was allocated to local tree-planting in Quincy and another $300,000 to salt marsh restoration along the Neponset River.
The Massachusetts Department of Environmental Protection classifies the Quincy facility as a major industrial emission source for nitrogen oxides and sulfur dioxide because of its high-pressure steam boilers and oleochemical refining processes, per state permitting records posted on Mass.gov. The plant previously converted its primary boilers from heavy fuel oil to natural gas. Twin Rivers is also the primary commercial customer operating the 2.7-mile Fore River Railroad, moving thousands of rail tank cars of fatty acids annually between Quincy Point and regional rail lines in Braintree, a route originally established in 1902 to serve the historic Fore River Shipyard, according to Trains Magazine.
Fire Suppression and Emergency Response Infrastructure
To manage its heavy industrial fire risks, the plant relies on a high-capacity deluge fire suppression system capable of dumping hundreds of thousands of gallons of water across the facility within minutes, earning it High Protected Risk status from insurer FM Global. That deluge system undergoes mandatory annual testing every September, according to FM Global's own assessment of the plant. Twin Rivers also participates in Quincy's Local Emergency Planning Committee and the U.S. Coast Guard Area Spill Response Committee to coordinate incident response along the Weymouth Fore River, per the company's sustainability disclosures — protocols relevant given the plant's proximity to public recreational spaces like Avalon Beach.
Just weeks before this fire, the Quincy Fire Department rolled out toxic-chemical-free, PFAS-free gear for its firefighters, making it one of the first departments in Massachusetts to eliminate PFAS from apparel ahead of a statewide ban taking effect in January 2027, as reported by Boston 25 News. WHDH did not report on the extent of injuries or damage as of its initial coverage, and Hoodline has not confirmed what caused the fire or whether it has been fully extinguished. This is a developing story and will be updated as more information becomes available.
