Approval and Promulgation of Air Quality Implementation Plan; Mashantucket Pequot Tribal Nation
The Environmental Protection Agency (EPA) proposes to approve the Mashantucket Pequot Tribal Nation's (MPTN or the Tribe) Tribal Implementation Plan (TIP) under the Clean Air Act (CAA) to regulate air pollution within the exterior boundaries of the Tribe's reservation. The proposed TIP is one of two CAA regulatory programs that comprise the Tribe's Clean Air Program (CAP). EPA approved the Tribe for treatment in the same manner as a State (Treatment as State or TAS) for purposes of administering New Source Review (NSR) and Title V operating permits under the CAA on July 10, 2008. In this action we propose to act only on those portions of MPTN's CAP that constitute a TIP containing severable elements of an implementation plan under CAA section 110(a). The proposed TIP includes permitting requirements for major and minor sources of air pollution. The purpose of the proposed TIP is to enable the Tribe to attain and maintain the National Ambient Air Quality Standards (NAAQS) within the exterior boundaries of its reservation by establishing a federally enforceable preconstruction permitting program.
Mercury and Air Toxics Standards for Power Plants Electronic Reporting Revisions
The U.S Environmental Protection Agency (EPA) is finalizing amendments to the electronic reporting requirements for the National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units (also known as the Mercury and Air Toxics Standards (MATS)). This action revises and streamlines the electronic data reporting requirements of MATS, increases data transparency by requiring use of one electronic reporting system instead of two separate systems, and provides enhanced access to MATS data. No new monitoring requirements are imposed by this final action; instead, this action reduces reporting burden, increases MATS data flow and usage, makes it easier for inspectors and auditors to assess compliance, and encourages wider use of continuous emissions monitoring systems (CEMS) for MATS compliance. In addition, this final action extends the current deadline for alternative electronic data submission via portable document format (PDF) files through December 31, 2023.
