A fire at a Houston recycling plant has led to the discovery of missing permits. The plant, Mammoth Metals Recycling, is located in the East End of Houston. The Texas Commission on Environmental Quality has rules in place for facilities that recycle certain materials.

For example, tire recycling facilities must register with the TCEQ. Further details about the fire and the plant's compliance with regulations are available from the Texas Commission on Environmental Quality and local news sources, including KPRC 2 Houston.
