The Environmental Protection Agency (EPA) is amending its hazard categories in the regulations (40 CFR part 370) for reporting under Sections 311 and 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA) due to the changes in the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS). OSHA’s HCS was revised in 2012 to conform to the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Under the revised HCS, chemical manufacturers and importers are required to evaluate their chemicals according to the new criteria adopted from GHS to ensure that they are classified and labeled appropriately. Manufacturers and importers are also required to develop standardized Safety Data Sheets (formerly known as “Material Safety Data Sheets/MSDS”) and distribute them to downstream users of their chemicals. These changes to OSHA’s HCS affect the reporting requirements under sections 311 and 312 of EPCRA.
