What happened

A major fire broke out at Aevitas Specialty Services' non-hazardous used-oil treatment and recycling plant at 663 Lycaste Street after employees noticed smoke and steam and heard a bang at about 02:30. The blaze burned for roughly seven hours, produced a black smoke plume visible for miles and extensively damaged the facility's waste-treatment machinery. One firefighter suffered a back injury and was hospitalized in stable condition; employees escaped without reported injury. The US Environmental Protection Agency said used oil and firefighting water overtopped secondary containment and migrated into the road; later reporting put the oily-water release at approximately 1,000 gallons. City records said the site held about 100,000 gallons of used oil and that the fire put a 200,000-gallon sulfuric-acid tank at risk. The cause remained undetermined in the reviewed follow-up reporting. The fire led to sustained scrutiny of the plant's compliance history: Detroit City Council cited 18 state citations, seven then-active violations and three violations found during a May 2025 inspection, and urged the city to pursue available enforcement. Aevitas later sought to rebuild and expand, but Detroit denied special land-use approval in July 2026; in August the company withdrew its separate state air-permit application after community opposition. The record therefore treats the post-fire shutdown and failed reopening effort as confirmed consequences, without presenting reported neighborhood health concerns as clinically established fire injuries.
