HOLLIS, NH -- TexaStone Quarries, which operates natural stone quarries and fabrication facilities in Garden City, TX, is the first company in the world to be named a certified stone producer that adheres to tough new sustainability standards. The news was announced today by the Natural Stone Council, which completed the development of the voluntary standards earlier this year.

Under the new council certification program, called ANSI/NSC-373 Sustainable Production of Natural Dimension Stone, six quarries operated by the company were awarded Gold certification and its closely-allied fabrication plant Silver certification after facility inspections by NSF International of Ann Arbor, MI, which also verified the firm's voluminous paperwork application.
