Partial Approval and Partial Disapproval of Air Quality Implementation Plans; Arizona; Nonattainment Plan for the Hayden SO2

The Environmental Protection Agency (EPA) is finalizing a partial approval and partial disapproval of an Arizona state implementation plan (SIP) revision for attaining the 2010 1-hour primary sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS or ``standard'') for the Hayden SO<INF>2</INF> nonattainment area (NAA). This SIP revision (hereinafter called the ``Hayden SO<INF>2</INF> Plan'' or ``Plan'') includes Arizona's attainment demonstration and other elements required under the Clean Air Act (CAA or ``Act'').

National Emission Standards for Hazardous Air Pollutants: Polyvinyl Chloride and Copolymers Production Reconsideration

On April 17, 2012, the U.S. Environmental Protection Agency (EPA) promulgated National Emission Standards for Hazardous Air Pollutants (NESHAP) for Polyvinyl Chloride and Copolymers (PVC) Production at major and area sources. Subsequently, the Administrator received and granted petitions for reconsideration of the emission limits in the 2012 final rules for process vents, process wastewater, and stripped resin for major and area sources.

National Emission Standards for Hazardous Air Pollutants for Chemical Recovery Combustion Sources at Kraft, Soda, Sulfite, and Stand-Alone Semichemical Pulp Mills; Standards of Performance for Kraft Pulp Mill Affected Sources for Which Construction, Recon

The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Chemical Recovery Combustion Sources at Kraft, Soda, Sulfite, and Stand-alone Semichemical Pulp Mills, and the New Source Performance Standards (NSPS) for Kraft Pulp Mills constructed, reconstructed, or modified after May 23, 2013. The final rule clarifies how to set operating limits for smelt dissolving tank (SDT) scrubbers used at these mills and corrects cross-reference errors in both rules.

Limited Approval, Limited Disapproval of Arizona Air Plan Revisions, Hayden Area; Sulfur Dioxide Control Measures-Copper Smelters

The Environmental Protection Agency (EPA) is finalizing a limited approval and limited disapproval of a revision to the Arizona State Implementation Plan (SIP). This revision concerns sulfur dioxide (SO<INF>2</INF>) emissions from the primary copper smelter in Hayden, Arizona. Specifically, we are taking action on a local rule submitted by the Arizona Department of Environmental Quality (ADEQ) that regulates these emissions under the Clean Air Act (CAA or the Act).

National Emission Standards for Hazardous Air Pollutants: Phosphoric Acid Manufacturing

This action finalizes an amendment to the national emission standards for hazardous air pollutants (NESHAP) for the Phosphoric Acid Manufacturing source category. The final amendment is in response to a petition for rulemaking on the mercury emission limit for existing phosphate rock calciners that was finalized on August 19, 2015 (``2015 Rule''). That emission limit was based on the maximum achievable control technology (MACT) floor for existing sources. All six of the existing calciners used to set this MACT floor are located at the PCS Phosphate Company, Inc.

Air Plan Approval; Connecticut; Control of Particulate Matter and Visible Emissions

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. This revision amends a Connecticut air-quality regulation for controlling particulate matter (PM) and visible emissions. The intended effect of this action is to define the process industries and activities to which this regulation applies, and to make technical corrections to an emission-rate calculation method. This action is being taken in accordance with the Clean Air Act.
