PORT NECHES, Texas (AP) - A plant that produces chemical and petroleum-based products in East Texas has exploded, blowing out windows on homes several miles away.

KFDM-TV reports that County Judge Jeff Branick says the explosion originated at a plant in Port Neches, near the Louisiana border, on Wednesday at about 1 a.m.

TPC Group says on its website that it provides a diverse range of quality products to chemical and petroleum-based companies worldwide. The site says the company employs more than 175 full-time employees and 50 contractors. Calls to the TPC Group went unanswered.

The Nederland Volunteer Fire Department said on its Facebook page that there is a mandatory evacuation for everyone within a half mile of the TPC plant. It said the evacuation could expand to a greater area.

Branick says no injuries have been reported so far, calling that a miracle.
