Environmental Protection Agency April 15, 2021 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is announcing a 30- day public comment period for the draft document titled, ``Technical Documentation for the Temperature Binning Framework'' (EPA 430-R-21- 004). This document provides technical documentation of a framework for analyzing the sector-specific impacts of climate change under different levels of warming. This approach serves as an alternative or complement to traditional scenario-based approaches in order to improve communication of results, comparability between studies, and flexibility to facilitate scenario analysis. The draft technical documentation will also be subject to external peer review. Prior to finalizing the draft document, EPA intends to carefully consider all comments received from the public and from external peer reviewers. This draft document is not final as described in EPA's information quality guidelines and does not represent and should not be construed to represent Agency policy or views. The draft document is available via the internet on EPA's web page at https://www.epa.gov/cira/ temperature-binning-framework.

The Environmental Protection Agency (EPA) is proposing to approve the regional haze state implementation plan (SIP) submitted by the District of Columbia (``the District'' or ``DC'') through the Department of Energy and Environment (DOEE) on November 8, 2019, as satisfying applicable requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule (RHR) for the program's second implementation period. The District's SIP submission addresses the requirement that states must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility in mandatory Class I Federal areas, including regional haze. EPA is taking this action pursuant to sections 110 and 169A of the CAA. EPA is also proposing to correct an error in the citations in our final approval of the District's revision to the Reasonably Available Control Technology for Major Stationary Sources of Nitrogen Oxides Rule (``DC NOX RACT rule'') according to our authority under Section 110(k)(6) of the CAA.
