Air Alliance Houston will hold a news conference Thursday morning following the large fire at Mammoth Metal Recycling in southeast Houston that burned for more than 24 hours and raised ongoing concerns about air quality in nearby communities.

The briefing comes after the fire at the Manchester-area facility, which involved a large pile of tires and recycling debris, sent heavy smoke across surrounding neighborhoods beginning Monday afternoon.

Air Alliance Houston says community air monitors detected elevated levels of fine particulate matter during the incident.
