Current through Register Vol. 28, No. 1, July 1, 2024
Section 1142-2.0 - Control of NO[x] Emissions from Industrial Boilers and Process Heaters at Petroleum Refineries2.1 Purpose 2.1.1 The purpose of Section 2.0 of this regulation is to reduce NOX emissions from Delaware's large industrial boilers and process heaters that are located at petroleum refineries.2.1.2 Under the 8-hour ozone national ambient air quality standard (NAAQS), the state of Delaware is part of the Philadelphia-Wilmington-Atlantic City, PA-DE-MD-NJ moderate non-attainment area (NAA). The entire NAA, including Delaware, is required by the Clean Air Act (CAA) to attain the 8-hour ozone NAAQS by 2010. After attainment, the area must maintain compliance with the NAAQS. By implementing Section 2.0 of this regulation, NOx emission reductions from the affected boilers and heaters shall contribute to (1) attainment and maintenance of the 8-hour ozone standard, and (2) improvement of the ambient air quality, in both Delaware and the entire NAA.2.1.3 Additionally, New Castle County of Delaware is a part of the Philadelphia-Wilmington-Camden, PA-DE-NJ NAA for the annual fine particulate matter (PM2.5) NAAQS, and is required by the CAA to attain the NAAQS by 2010. Since NOx is a significant precursor to PM2.5 formation, reducing NOx emissions will also assist in attainment and maintenance of the PM2.5 standard.2.2 Applicability and Compliance Dates 2.2.1 Section 2.0 of this regulation applies to any industrial boiler or process heater with a maximum heat input capacity of equal to or greater than 200 million BTUs per hour (mmBTU/Hour), which is operated or permitted to operate within a petroleum refinery facility on July 11, 2007.
