Notification of Public Teleconferences of the Science Advisory Board; Environmental Economics Advisory Committee
The Environmental Protection Agency (EPA) Science Advisory Board (SAB) Staff Office announces public teleconferences of the SAB Environmental Economics Advisory Committee to conduct a review of EPA's Draft White Paper ``Retrospective Study of the Costs of EPA Regulations: An Interim Report'' (March 2012).
Protection of Stratospheric Ozone: Amendment to HFO-1234yf SNAP Rule for Motor Vehicle Air Conditioning Sector
The U.S. Environmental Protection Agency (EPA) is taking direct final action to revise one of the use conditions required for use of hydrofluoroolefin (HFO)-1234yf (2,3,3,3-tetrafluoroprop-1-ene), a substitute for ozone-depleting substances (ODSs) in the motor vehicle air conditioning end-use within the refrigeration and air conditioning sector, to be acceptable subject to use conditions under EPA's Significant New Alternatives Policy (SNAP) program. The revised use condition incorporates by reference a revised standard from SAE International.
Approval and Promulgation of Implementation Plans; State of Colorado; Regional Haze State Implementation Plan
EPA is proposing to approve a State implementation plan (SIP) revision submitted by the State of Colorado on May 25, 2011 that addresses regional haze (RH). EPA is proposing to determine that the plan submitted by Colorado satisfies the requirements of the Clean Air Act (CAA or ``the Act'') and our rules that require states to prevent any future and remedy any existing man-made impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is taking this action pursuant to section 110 of the CAA.
Special Conditions: XtremeAir GmbH, XA42; Acrobatic Category Aerodynamic Stability
These special conditions are issued for the XtremeAir GmbH XA42 airplane. The XA42 airplane has a novel or unusual design feature associated with its static stability. This airplane can perform at the highest level of aerobatic competition. To be competitive, the aircraft was designed with positive and, at some points, neutral stability within its flight envelope. Its lateral and directional axes are also decoupled from each other providing more precise maneuvering. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. These special conditions are only applicable to aircraft certified solely in the acrobatic category.
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
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 control devices used to control process vents from reactors, distillation and other operations, as well as from emissions from storage vessels, transfer operations and equipment leaks that are routed to control devices. Establishing these Uniform Standards is consistent with the objectives of Executive Order 13563, Improving Regulation and Regulatory Review, issued on January 18, 2011. In the future, as we periodically review and, if necessary, revise new source performance standards and national emission standards for hazardous air pollutants, as required by the Clean Air Act, we can direct those rulemakings to the proposed Uniform Standards, provided the Uniform Standards meet the applicable statutory stringency requirements for the specific rulemaking. The proposed Uniform Standards would ensure consistency and streamline recordkeeping and reporting requirements for facilities with storage vessels and transfer operations, equipment leaks and process vents that must comply with multiple regulations.
Hazard Communication
In this final rule, OSHA is modifying its Hazard Communication 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 reducing the incidence of chemical-related occupational illnesses and injuries. The modifications to the standard include revised criteria for classification of chemical hazards; revised labeling provisions that include requirements for use of standardized signal words, pictograms, hazard statements, and precautionary statements; a specified format for safety data sheets; and related revisions to definitions of terms used in the standard, and requirements for employee training on labels and safety data sheets. OSHA is also modifying provisions of other standards, including standards for flammable and combustible liquids, process safety management, and most substance-specific health standards, to ensure consistency with the modified HCS requirements. The consequences of these modifications will be to improve safety, to facilitate global harmonization of standards, and to produce hundreds of millions of dollars in annual savings.
