The Coast Guard's subsequent investigation did not accuse Mallard of anything, but did note that the barge was not an "inspected vessel" subject to comprehensive Coast Guard regulation. The Occupational Safety and Health Administration (OSHA) then cited Mallard for violations of the Occupational Safety and Health Act (Act) of 1970. Mallard challenged OSHA's jurisdiction to issue the citations on the grounds that Rig 52 was not a "workplace" under section 4(a) of the Act and that section 4(b)(1) of the Act pre-empted OSHA jurisdiction because the Coast Guard had exclusive authority to prescribe and enforce occupational safety and health standards on vessels such as Rig 52. Rejecting both arguments, an Administrative Law Judge found that Rig 52 was a "workplace" under the Act and held that the Coast Guard had not pre-empted OSHA's jurisdiction. In reversing, the Court of Appeals held that the Coast Guard's exclusive jurisdiction over the regulation of seamen's working conditions aboard vessels such as Rig 52 precluded OSHA's regulation under section 4(b)(1), and that this pre-emption encompassed both inspected and uninspected vessels.</p> http://www.oyez.org/cases/2000-2009/2001/2001_00_927/ <p>Acting under authority of the Occupational Safety and Health Act of 1970, the Secretary of Labor, after having demonstrated a link between exposure to benzene and leukemia, set a standard reducing the airborne concentrations of benzene to which workers could be exposed. The standard reduced the allowable amount from 10 parts per million (ppm) to one ppm. This case was decided together with Marshall v. American Petroleum Institute.</p> http://www.oyez.org/cases/1970-1979/1979/1979_78_911/ <p>No details yet.</p> http://www.oyez.org/cases/1990-1999/1990/1990_89_1541/ <p>No details yet.</p> http://www.oyez.org/cases/1970-1979/1979/1979_78_1870/
