Title 7 DNREC 1100 AirQuality ManagementSection 1142 Specific Emission Control Requirements G+l11/2007xxlxx/2009 2.0 Control ofNOx Emissionsfrom Industrial Boilers and Process Heaters at Petroleum Refineries 2.1 Purpose The purpose ofSection 2.0 ofthis regulation is to reduce NOx emissions from Delaware's large industrial boilers and process heaters that are located at petroleum refineries. Under the 8-hour ozone national ambient air quality standard (NAAQS), the state of Delaware is part ofthe Philadelphia-Wilmington-Atlantic City, PA-DE-MD-NJ moderate non-attainment area (NAA). The entire NAA, including Delaware, is

... required bythe Clean AirAct (CAA) to attain the 8-hourozone NAAQS by2010. After

attainment, the area must maintain compliance with the NAAQS. By implementing Section 2.0 ofthis 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 ofthe ambient air quality, in both Delaware and the entire NAA. Additionally, New Castle County of Delaware is a part of the PhiladelphiaWilmington-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 attainmentand maintenance ofthe PM2.5standard. 2.2 Applicability and Compliance Dates 2.2.1 Section The provisions of 2.0 of this regulation applies apply to any industrial boilerorprocess heaterwith a maximum heat input capacity ofequal to or greater than 200 million BTUs per hour (mmBTUlHour) (except for any Fluid Catalytic Cracking Unit carbon monoxide (CO) boiler), which is operated orpermitted to operate within a petroleum refineryfacility on the effective date ofthis section 2.0 ofthis regulation. This comprises the following nine (9) units atthe Delaware City refinery: 2.2.1.1 Crude UnitVacuum Heater (Unit21-H-2); 2.2.1.2 Crude UnitAtmospheric Heater (Unit21-H-701); 2.2.1.3 Fluid Coking Unit Carbon Monoxide boiler (Unit 22-H-3);

The owner or operator of any industrial boiler or process heater identified in Seotion 2.2.1 of this regulation shall not allow 

### NO. to be emitted at a rate that exoeeds meetthe applicable NOx emission limitation identified in the following: 2.3.1 For the Fluid Coking Unit Carbon Monoxide boiler (Unit 22-H-3), Reserved. 2.3.2 For the Steam Methane Reformer (SMR) Heater (Unit 37-H-1), Reserved.

22.3.3 For Boiler 1 (Unit 80-1), Boiler 3 (Unit 80-3) and Boiler 4 (Unit 80-4), shall not operate after May 1, 2011. On or before May 1, 2011 the ownBf-e.F operatorofBoiler 3 ane Boiler

### 4 shall request that-any operating permit issuee by the Department be cancellee. 0.015 Ib/mmBTU, on a 24-hour rolling average basis. 2.3.4 For any unit not covered by 2.3.1, 2.3.2, or 2.3.3 of this regulation, 0.04 Ib/mmBTU, on a 24-hour rolling average basis. 2.3.5. The standards set out in 2.3 of this regulation shall not apply to the start-up and shutdown of equipment when emissions from such equipment during a start-up and shutdown are addressed in an operation permit issued pursuantto the provisions of2.0 of7 DE Admin. Code 1102. 2.4 Monitoring Requirements. Compliance with the NOx emission standards specified in 2.3.1, 2.3.2, and 2.3.4 of this regulation shall be determined based on CEM data collected in accordance with the appropriate requirements set forth in 40 CFR, Part 60, Appendix B, Performance Specification 2, and the QNQC requirements in 40 CFR Part 60, Appendix F. 2.5 Recordkeeping and Reporting Requirements 2.5.1 Not later than 180 days after the effective date of Section 2.0 of this regulation, any person subject to Seotion 2.0 ofthis regulation shall develop, and submit to the Department, a schedule for bringing the affected emission**unit~** or units, identified in Seotion 2.2.4 of this regulation, into compliance with the requirements of Seotion 2.3 of this regulation.
