1142 Specific Emission Control Requirements

1. TITLE OF THE REGULATION:

Revise 7 DE Admin. Code 1142 Specific Emission Control Requirements

2. BRIEF SYNOPSIS OF THE SUBJECT, SUBSTANCE AND ISSUES:

EPA, in 80 FR 33840 (6/12/2015 - final) identified the State Implementation Plans (SIPs) of 36 states as inadequate because they allegedly allowed unregulated excess emissions. Seven Delaware regulations were cited in this SIP Call because the EPA believes the regulations do not appropriately restrict emissions during start-up or shutdown events. This action is to revise one of the cited Delaware's regulations to comply with the EPA SIP Call and avoid the imposition of federal sanctions.

3. POSSIBLE TERMS OF THE AGENCY ACTION:

None.

4. STATUTORY BASIS OR LEGAL AUTHORITY TO ACT:

7 Delaware Code, Chapter 60.

5. OTHER REGULATIONS THAT MAY BE AFFECTED BY THE PROPOSAL:

None.

6. NOTICE OF PUBLIC COMMENT:

There will be a hearing on this proposed amendment and the other EPA cited Delaware rules on October 25, 2016 beginning at 6pm in the Dover DAQ offices at State Street Commons, 100 West Water Street, Suite 6A, Dover, DE 19904. Interested parties may submit comments in writing to David Fees, Division of Air Quality, 100 West Water Street, Suite 6A, Dover, DE 19904 and/or statements and testimony may be presented either orally or in writing at the public hearing.

1142 Specific Emission Control Requirements

12/12/2001 xx/11/2016

1.0 Control of NOx Emissions from Industrial Boilers

1.1 Purpose

New Castle County and Kent County are part of the Philadelphia-Wilmington-Trenton 1-hour ozone non-attainment area. All areas of Delaware impact this non-attainment area. On December 19, 1999, the EPA identified an emission reduction ???shortfall??? associated with this non-attainment area. Promulgation of Section 1.0 of this regulation is one measure that the Department is taking to mitigate this shortfall.

In determining the applicability of Section 1.0 of this regulation, the Department attempted to minimize the impact on facilities that recently installed NOx controls under 7 DE Admin. Code 1112 (NOx RACT) and 7 DE Admin. Code 1137/1139 (NOx Budget Trading Program). The Department did this by regulating only large sources that, as of the effective date of Section 1.0 of this regulation, emitted NOX at a rate greater than the rate identified in Table 3-1 of 7 DE Admin. Code 1112, were not equipped with NOx emission control technology, and were not subject to the requirements of 7 DE Admin. Code 1139. In effect, Section 1.0 of this regulation regulates sources that remain high NOx emitters after the application of RACT and post RACT requirements, and that have not committed substantial capital funds to reduce NOx emissions.

1.2 Applicability

1.2.1 The provisions of Section 1.0 of this regulation apply to any person that owns or operates any combustion unit with a maximum heat input capacity of equal to or greater than 100 million btu per hour, except that Section 1.0 of this regulation shall not apply to any unit that, as of the effective date of Section 1.0 of this regulation:

1.2.1.1 Emits NOx at a rate equal to or less than the rate identified in Table 3-1 of 7 DE Admin. Code 1112.

1.2.1.2 Is equipped with low NOx burner, flue gas recirculation, selective catalytic reduction, or selective non-catalytic reduction technology.

1.2.1.3 Is subject to the requirements of 7 DE Admin. Code 1139.

1.2.2 The requirements of Section 1.0 of this regulation are in addition to all other state and federal requirements.

1.2.3 Affected persons shall comply with the requirements of subsection 1.3 of this regulation as soon as practicable, but no later than May 1, 2004.

1.3 Standards.

1.3.1 The NOx emission rate from any unit subject to Section 1.0 of this regulation shall be equal to or less than the following:

1.3.1.1 Between May 1st through September 30th of each year, inclusive: 0.10 lb/mmBTU, 24-hour calendar day average.

1.3.1.2 During all times that gaseous fuel is being fired: 0.10 lb/mmBTU, 24-hour calendar day average.

1.3.1.3 During all times not covered by subsection 1.3.1.1 and subsection 1.3.1.2 of this regulation: 0.25 lb/mmBTU, 24-hour calendar day average.

1.3.2 As an alternative to compliance with the requirements of subsection 1.3.1 of this regulation, compliance may be achieved through the procurement and retirement of NOx allowances authorized for use under 7 DE Admin. Code 1139, as follows:

1.3.2.1 The actual 24-hour calendar day average NOx emission rate in pounds per million btu shall be determined for each day of unit operation, using CEMs operated in accordance with subsection 1.4 of this regulation.

1.3.2.2 The actual heat input to each unit in million btu shall be determined for each day of unit operation, using methods proposed by the person subject to Section 1.0 of this regulation and acceptable to the Department.

1.3.2.3 0.10 or 0.25, as applicable and consistent with subsection 1.3.1 of this regulation, shall be subtracted from the rate determined in subsection 1.3.2.1 of this regulation.

1.3.2.4 To obtain the number of pounds of NOx emitted for a particular day, the emission rate determined in subsection 1.3.2.3 of this regulation shall be multiplied by the heat input to the unit for that day determined in subsection 1.3.2.2 of this regulation. If the emission rate determined in subsection 1.3.2.3 of this regulation is equal to or less than zero, then the number of pounds of NOx emitted for that day shall be zero.

1.3.2.5 Not later than the 20th day of each month:

1.3.2.5.1 The number of pounds of NOx emissions calculated pursuant to subsection 1.3.2.4 of this regulation shall be summed for each calendar month, the result shall be divided by 2000, and shall be rounded to the nearest whole ton.

1.3.2.5.2 For each ton of NOx emissions calculated pursuant to subsection 1.3.2.5.1 of this regulation, records shall be maintained demonstrating that one NOx allowance owned by the person subject to Section 1.0 of this regulation is identified and available, by serial number, for retirement.

1.3.2.6 Not later than February 1 of each calendar year, the NOx allowances identified pursuant to subsection 1.3.2.5.2 of this regulation for the previous calendar year, shall be submitted to the Department for retirement. Such submission shall detail the calculations specified in subsection 1.3.2.1 through subsection 1.3.2.5 of this regulation, and shall indicate the serial number of each allowance to be retired.

1.4 Monitoring Requirements. Compliance with the NOx emission standards specified in Section 1.0 of this regulation shall be determined based on CEM data collected in accordance with the requirements of subsection 3.1.2 of 7 DE Admin. Code 1117 (Performance Specification 2), and in compliance with the requirements of 40 CFR, Part 60, Appendix F.

1.5 Recordkeeping and Reporting Requirements.

1.5.1 Not later than 180 days after the effective date of Section 1.0 of this regulation, any person subject to Section 1.0 of this regulation shall develop, and submit to the Department for approval, a schedule for bringing the affected emission unit or units into compliance with the requirements of Section 1.0 of this regulation.

2.0 Control of NOx Emissions from Industrial Boilers and Process Heaters at Petroleum Refineries

2.1 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.
