NSC 373 Standard

Sustainability at TexaStone Quarries
TSQ2017-PlatinumQuarrierTSQ2017-PlatinumFabricator
TexaStone Quarries started the path to becoming more sustainable in 2013 earning the first ever certifications in the Stone Industry under the ANSI/NSC 373 Standard. We were proud to be awarded Gold Quarrier and Silver Fabricator in 2014. Over the next three years we focused on improving our operations even more. In June 2017, we successfully achieved the Platinum level of certification in both our Quarry and Fabrication operations.

About the NSC 373 Standard

The ANSI/NSC 373 Sustainable Production of Natural Dimension Stone was created to recognize and drive sustainability practices in the natural stone industry. The standard applies to quarriers and processors of natural dimension stone and offers criteria such as environmental, ecological, social responsibility and human health/safety parameters to follow. It is based on both required and optional point totals to achieve a certification level of Bronze, Silver, Gold or Platinum. Monitoring of the standard’s criteria is done year-round with yearly audits from NSF and re-certification through a site visit every three years.

Recently, this standard has been recognized by the USGBC’s LEED v4 building certification program and ILFI’s Living Building Challenge version 3.1. This opens the door for design teams to utilize natural stone in their projects to reach their sustainability goals.

The Standard was developed by the Natural Stone Council, NSF International and Ecoform.
