A lawsuit was filed Thursday against the owners and operators of a pipeline that exploded last year in Lincoln County. 58-year old Lisa Derringer was killed, several others were injured.

The suit lists over 80 people who suffered injuries or property damage in the blast on August 1, 2019. 

The lawsuit claims the  Texas Eastern Transmission LP, a subsidiary of Enbridge, a Canadian-based energy company, failed to properly maintain the pipeline.

The lawsuit names several other companies, including an unnamed operator of Texas Eastern’s compressor station near Danville, and seeks an unspecified amount of money.

The explosion is still under investigation by federal authorities.
