Title 7 DNREC 1100 AirQuality ManagementSection 1142 Specific Emission Control Requirements 11/11/2009 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 (NMOS), the state of Delaware is part ofthe Philadelphia-Wilmington-Atlantic City, PA-DE-MD-NJ moderate non-attainment area (NM). The entire NM, including Delaware, is required bythe Clean AirAct (CM)to attain the 8-hourozone NMOS by2010. After attainment, the area must maintain compliance with the NMOS. 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 NM. Additionally, New Castle County of Delaware is a part of the PhiladelphiaWilmington-Camden, PA-DE-NJ NM for the annual fine particulate matter (PM2

.5

) NMOS, and is required by the CM to attain the NMOS by 2010. Since NOx is a significant precursor to PM2

.5formation, reducing NOx emissions will also assist in attainmentand maintenance ofthe PM2.5 standard. 2.2 Applicabilityand Compliance Dates 2.2.1 Section 2.0 ofthis regulation applies to any industrial boileror process heater with a maximum heat input capacity of equal to or greater than 200 million BTUs per hour (mmBTUlHour) (except for any Fluid Catalytic Cracking Unit carbon monoxide (CO) boiler), which is operated or permitted to operate within a petroleum refinery facility on the effective date of this section. This comprises thefollowing nine (9) units atthe Delaware City refinery: 2.2.1.1 Crude UnitVacuum Heater(Unit 21-H-2); 2.2.1.2 Crude UnitAtmospheric Heater(Unit 21-H-701); 2.2.1.3 Fluid Coking Unit Carbon Monoxide boiler(Unit 22-H-3);

12.2.1.4 Steam Methane Reformer Heater (Unit 37-H-1); 2.2.1.5 Continuous Catalyst Regenerator Reformer Heater (Unit 42-H1,2,3); 2.2.1.6 Boiler 1 (Unit 80-1); 2.2.1.7 Boiler2 (Unit 80-2); 2.2.1.8 Boiler3 (Unit 80-3); 2.2.1.9 Boiler4 (Unit 80-4). 2.2.2 The requirements ofSection 2.0 ofthis regulation are in addition to all otherstate and federal requirements. 2.2.3 The following units shall be in compliance with the requirements of Section 2.0 of this regulation on and after July 11, 2007: Crude Unit Atmospheric Heater (Unit 21-H-701), Steam Methane Reformer Heater (Unit 37-H-1) and Boiler2 (Unit 80-2). 2.2.4 The following units shall be in compliance with the requirements of Section 2.0 ofthis regulation as soon as practicable, but not laterthan: 2.2.4.1 December 31, 2008: Boiler 1 (Unit 80-1) and Crude Unit vacuum Heater(Unit21-H-2). 2.2.4.2 May 1, 2011: Boiler3 (Unit 80-3)and Boiler4 (Unit 80-4). 2.2.4.3 December 31, 2012: Continuous Catalyst Regenerator Reformer Heater (Unit42-H-1, 2, 3). 2.3 Standards. The owner or operator of any industrial boiler or process heater identified in Section 2.2.1 of this regulation shall meet the applicable NOx emission limitation identified in thefollowing sections: 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. 2.3.3 For Boiler 1 (Unit 80-1), Boiler 3 (Unit 80-3) and Boiler 4 (Unit 80-4), 0.015Ib/mmBTU, on a 24-hour rolling average basis.

22.3.4 For any unit not covered by 2.3.1, 2.3.2, or2.3.3, 

### 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 of§2 ofRegulation 

### 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 QA/QC 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 Section 

### 2.0 ofthis regulation shall develop, and submit to the Department, a schedule for bringing the affected emission unites). identified in Section 2.2.4, into compliance with the requirements of Section 2.3 ofthis regulation. Such schedule shall include, ata minimum, all of thefollowing: 2.5.1.1 The method bywhich compliance will be achieved. 2.5.1.2 The dates by which the affected person plans to complete the following major increments ofprogress, as applicable: 2.5.1.2.1 Completion ofengineering; 2.5.1.2.2 Submission ofpermit applications; 2.5.1.2.3 Awarding of contracts for construction and/or installation; 2.5.1.2.4 Initiation ofconstruction; 2.5.1.2.5 Completion ofconstruction; 2.5.1.2.6 Commencementoftrial operation; 2.5.1.2.7 Initial compliancetesting; 2.5.1.2.8 Submission ofcompliancetesting reports;
