1142 Specific Emission Control Requirements

Regulation No. 42 1142 Specific Emission Control Requirements

12/12/2001

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 1.0 of this regulation is one measure that the Department is taking to mitigate this shortfall.

In determining the applicability of this Section 1.0 of this regulation, the Department attempted to minimize the impact on facilities that recently installed NOx controls under Regulation No. 12 7 DE Admin. Code 1112 (NOx RACT) and Regulation No. 37/39 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 this Section 1.0 of this regulation, emitted NOX at a rate greater than the rate identified in Table I 3-1 of Regulation No. 12 7 DE Admin. Code 1112, were not equipped with NOx emission control technology, and were not subject to the requirements of Regulation No. 39 7 DE Admin. Code 1139. In effect, this 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 This section applies The provisions of 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 this section 1.0 of this regulation shall not apply to any unit that, as of the effective date of this 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 I 3-1 of Regulation No. 12 7 DE Admin. Code 1112. of the State of Delaware “Regulations Governing the Control of Air Pollution.”

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 Regulation No. 39 7 DE Admin. Code 1139. of the State of Delaware “Regulations Governing the Control of Air Pollution.”

1.2.2 The requirements of this 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 paragraph 1.3 of this Section 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 this 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 Section 1.3.1.1 and 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 paragraph 1.3.1 of this Section regulation, compliance may be achieved through the procurement and retirement of NOx allowances authorized for use under Regulation No. 39 7 DE Admin. Code 1139, of the State of Delaware “Regulations Governing the Control of Air Pollution,” 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 paragraph 1.4 of this section 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 this 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 paragraph 1.3.1 of this section regulation, shall be subtracted from the rate determined in paragraph 1.3.2.1 of this section regulation.

1.3.2.4 To obtain the number of pounds of NOx emitted for a particular day, the emission rate determined in paragraph 1.3.2.3 of this section regulation shall be multiplied by the heat input to the unit for that day determined in paragraph 1.3.2.2 of this section regulation. If the emission rate determined in paragraph 1.3.2.3 of this section 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 paragraph 1.3.2.4 of this section 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 paragraph 1.3.2.5.1 of this regulation, records shall be maintained demonstrating that one NOx allowance owned by the person subject to this 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 paragraph 1.3.2.5.2 of this Section regulation for the previous calendar year, shall be submitted to the Department for retirement. Such submission shall detail the calculations specified in 1.3.2.1 through 1.3.2.5 above 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 this section 1.0 of this regulation shall be determined based on CEM data collected in accordance with the requirements of Regulation 17, Section 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 this Section 1.0 of this regulation, any person subject to this Section 1.0 of this regulation shall develop, and submit to the Department for approval, a schedule for bringing the affected emission unit(s) or units into compliance with the requirements of this Section 1.0 of this regulation. Such schedule shall include, at a minimum, all of the following:
