Alternative Methods for Calculating Off-Cycle Credits Under the Light-Duty Vehicle Greenhouse Gas Emissions Program: Application From Volkswagen Group of America, Inc.
EPA is requesting comment on an application from Volkswagen Group of America, Inc. (``Volkswagen'') for off-cycle carbon dioxide (CO2) credits under EPA's light-duty vehicle greenhouse gas emissions standards. ``Off-cycle'' emission reductions can be achieved by employing technologies that result in real-world benefits, but where that benefit is not adequately captured on the test procedures used by manufacturers to demonstrate compliance with emission standards. EPA's light-duty vehicle greenhouse gas program acknowledges these benefits by giving automobile manufacturers several options for generating ``off-cycle'' CO2 credits. Under the regulations, a manufacturer may apply for CO2 credits for off-cycle technologies that result in off-cycle benefits. In these cases, a manufacturer must provide EPA with a proposed methodology for determining the real-world off-cycle benefit. Volkswagen has submitted an application that describes methodologies for determining off-cycle credits from technologies described in their application. Pursuant to applicable regulations, EPA is making the Volkswagen's off-cycle credit calculation methodologies available for public comment.

EPA reviewed these revisions and determined that they will not impact air quality and will ensure consistency between the state and federally approved rules.
Proposed Information Collection Request; Comment Request; NESHAP for Industrial, Commercial, and Institutional Boilers Area Sources (Renewal)
The Environmental Protection Agency (EPA) is planning to submit an information collection request (ICR), NESHAP for Industrial, Commercial, and Institutional Boilers Area Sources (EPA ICR No. 2253.04, OMB Control No. 2060-0668) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. Before doing so, EPA is soliciting public comments on specific aspects of the proposed information collection as described below. This is a proposed extension of the ICR, which is currently approved through October 31, 2018. An agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number.
Light-Duty Vehicle GHG Program Technical Amendments
EPA is proposing two technical corrections to the light-duty vehicle greenhouse gas (GHG) emissions standards regulations finalized in the 2012 rulemaking that established standards for model years 2017- 2025 light-duty vehicles. First, EPA proposes to correct regulations pertaining to how auto manufacturers must calculate credits for the GHG program's optional advanced technology incentives. The regulations currently in place result in auto manufacturers receiving fewer credits than the agency intended for electric vehicles, plug-in hybrid electric vehicles, fuel cell electric vehicles, and natural gas fueled vehicles. Auto manufacturers requested through a petition letter submitted jointly by the Auto Alliance and Global Automakers in June 2016 that EPA correct the regulations to provide the intended level of credits for these technologies. Second, the regulations regarding how manufacturers must calculate certain types of off-cycle credits contain an error and are inconsistent with the 2012 final rule preamble, raising implementation concerns for some manufacturers. The proposed amendments would clarify the calculation methodology in the regulations. Both of these corrections allow the program to be implemented as originally intended. The proposed corrections are not expected to result in any additional regulatory burdens or costs.
Air Plan Approval; Connecticut; Plan Submittals for the 2008 Ozone National Ambient Air Quality Standard
The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Connecticut. The SIP revisions are for the Greater Connecticut and the Connecticut portion of the New York-Northern New Jersey-Long Island, NY-NJ-CT moderate ozone nonattainment areas. EPA is approving submittals which include 2011 base year emissions inventories, an emissions statement certification, reasonable further progress (RFP) demonstrations, reasonably available control measures (RACM) analyses, motor vehicle emissions budgets, and contingency measures. This action is being taken in accordance with the Clean Air Act (CAA).

This action is being taken in accordance with the Clean Air Act.
Protection of Stratospheric Ozone: Revisions to the Refrigerant Management Program's Extension to Substitutes
The Clean Air Act (CAA) prohibits knowingly venting or releasing ozone-depleting and substitute refrigerants in the course of maintaining, servicing, repairing, or disposing of appliances or industrial process refrigeration. On November 18, 2016, EPA finalized a rule that updated the existing refrigerant management requirements and extended requirements that previously applied only to refrigerants containing an ozone-depleting substance (ODS) to substitute refrigerants such as hydrofluorocarbons that are subject to the venting prohibition (i.e., those that have not been exempted from that prohibition). The Agency is revisiting the aspects of the 2016 Rule that apply to equipment containing such substitute refrigerants. This action proposes changes to the legal interpretation that supported that rule and amendments to the regulations based on the revised interpretation. More specifically, in connection with the proposed changes to the legal interpretation, EPA is proposing to revise the appliance maintenance and leak repair provisions so they apply only to equipment using refrigerant containing a class I or class II substance. Based on this proposed limitation of the leak repair requirements, this document further proposes to revise the list of practices that must be followed in order for refrigerant releases to be considered de minimis to clarify that the reference to following leak repair practices only applies to equipment that contains ODS refrigerant. EPA is also taking comment on whether, in connection with the proposed changes to the legal interpretation, the 2016 Rule's extension of subpart F refrigerant management requirements to such substitute refrigerants should be rescinded in full. Additionally, EPA is proposing to extend by six to twelve months the January 1, 2019 compliance date for when appliances containing only substitute refrigerants subject to the venting prohibition must comply with the appliance maintenance and leak repair provisions.
