The federal rulemaking process depends on sound science, especially when human lives are at stake. A proposed rule from the Occupational Safety and Health Administration (OSHA) would stiffen regulations for crystalline silica, a group of minerals used in numerous industries, including hydraulic fracturing. Prolonged exposure to respirable crystalline silica is associated with silicosis, an incurable disease that causes impaired respiratory function and scarring of the lungs. Unfortunately, OSHA’s proposed rule fails the sound science test.
