Big Brown Mine
In operation since 1971, the Big Brown Mine produces between four to six million tons of lignite each year. Located near Fairfield, Texas, the mine helps meet the power needs of central Texas by supplying fuel to the adjacent 1,150 megawatt Big Brown Steam Electric Station operated by Luminant Generation Company LLC. As an environmental and engineering consultant for Big Brown mining operations, HDR provides permitting support and annual compliance reviews to support the requirements of the Surface Mining Control and Reclamation Act and Section 404 of the Clean Water Act.
Additional services include mitigation planning for mine impacts to waters of the United States and coal ash volume calculations for disposal and analysis of existing disposal cells at an on-site industrial landfill.
