National Uniform Emission Standards for Storage Vessel and Transfer Operations, Equipment Leaks, and Closed Vent Systems and Control Devices; and Revisions to the National Uniform Emission Standards General Provisions

On March 26, 2012, the EPA proposed the National Uniform Emission Standards for Storage Vessels and Transfer Operations, Equipment Leaks, and Closed Vent Systems and Control Devices, herein referred to as Uniform Standards. The EPA is extending the deadline for written comments on the proposed amendments by 90 days to September 24, 2012. The EPA received requests for this extension from the American Petroleum Institute (API) and the American Chemistry Council (ACC). API and ACC each requested an extension in order to fully evaluate the potential impact of the Uniform Standards on subparts applicable to the refining and chemical industries, respectively. The EPA finds these requests to be reasonable due to the multiple source categories potentially affected by this action.
