In 1999 and 2001, OSHA was petitioned to issue an emergency temporary standard for permissible exposure limit (PEL) to beryllium by the United Steel Workers (formerly the Paper Allied-Industrial, Chemical, and Energy Workers Union), Public Citizen Health Research Group, and others. The Agency denied the petitions but stated its intent to begin data gathering to collect needed information on beryllium's toxicity, risks, and patterns of usage. On November 26, 2002, OSHA published a Request for Information (RFI) (67 FR 70707) to solicit information pertinent to occupational exposure to beryllium, including: current exposures to beryllium; the relationship between exposure to beryllium and the development of adverse health effects; exposure assessment and monitoring methods; exposure control methods; and medical surveillance. In addition, the Agency conducted field surveys of selected worksites to assess current exposures and control methods being used to reduce employee exposures to beryllium. OSHA convened a Small Business Advocacy Review Panel under the Small Business Regulatory Enforcement Fairness Act (SBREFA) and completed the SBREFA Report in January 2008. OSHA also completed a scientific peer review of its draft risk assessment.
