In this final rule, OSHA is modifying its Standard (HCS) to conform to the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS). OSHA has determined that the modifications will significantly reduce costs and burdens while also improving the quality and consistency of information provided to employers and employees regarding chemical hazards and associated protective measures. Consistent with the requirements of Executive Order 13563, which calls for assessment and, where appropriate, modification and improvement of existing rules, the Agency has concluded this improved information will enhance the effectiveness of the HCS in ensuring that employees are apprised of the chemical hazards to which they may be exposed, and in redu...

The EPA is proposing National Uniform Emission Standards for Storage Vessels and Transfer Operations, Equipment Leaks and Control Devices, herein referred to as Uniform Standards. The EPA is also proposing supplemental revisions to the National Uniform Emission Standards General Provisions, which were proposed with the National Uniform Emission Standards for Heat Exchange Systems, signed by the EPA Administrator on November 30, 2011. The proposed Uniform Standards would be referenced, as appropriate, in future revisions to new source performance standards and national emission standards for hazardous air pollutants for individual source categories that are part of the chemical manufacturing and refining industries that have storage vessels and transfer operations, equipment leaks or con...
