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 regulations in place for facilities that recycle certain materials.

For instance, tire recycling facilities are required to register with the TCEQ. Further information about the fire and the plant's compliance with regulations is available from the Texas Commission on Environmental Quality and local news sources, including KPRC 2.
