7:27 19.7 Industrial/commercial/institutional boilers and other indirect heat exchangers

(g) On and after March 7, 2007, the owner or operator of an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least five million BTU per hour, whether or not it is located at a major NO_X facility, shall adjust the combustion process annually in accordance with the procedure set forth at N.J.A.C. 7:27-19.16 and the following schedule:

1. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least five million BTU per hour, but less than 10 million BTU per hour, in the same quarter of each calendar year, beginning in 2010;
2. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least 10 million BTU per hour, but less than 20 million BTU per hour, in the same quarter of each calendar year beginning in 2008; or
3. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least 20 million BTU per hour or greater, in the same quarter of each calendar year beginning in 2007.

7:27 19.16 Adjusting combustion processes

(a) When any provision of this subchapter requires the adjustment of a combustion process for any equipment or source operation, other than stationary combustion turbines and reciprocating engines, the owner or operator of the equipment or source operation shall:

1. Inspect the burner, and clean or replace any components of the burner as necessary;
2. Inspect the flame pattern and make any adjustments to the burner necessary to optimize the flame pattern consistent with the manufacturer’s specifications;
3. Inspect the system controlling the air to fuel ratio, and ensure that it is correctly calibrated and functioning properly;
4. Minimize total emissions of NO_X and CO consistent with the manufacturer’s specifications;
5. Measure the concentrations in the effluent stream of NO_X, CO and O₂ in ppmvd, before and after the adjustment is made; and
6. Convert the emission values of the NO_X, CO and O₂ concentrations measured pursuant to (a)5 above to pounds per million BTU (lb/MMBTU) according to the following formula:

lb/MMBTU	=	ppmvd × MW × Fdry factor × O2 correction factor
		387,000,000

Where:
ppmvd is the concentration in parts per million by volume, dry basis, of NO_X or CO;
MW is the molecular weight for NO_X (= 46 lb/lb-mole) or CO (= 28 lb/lb-mole);
F_dry factor for natural gas = 8,710 dscf/MM BTU; for residual or fuel oil = 9,190 dscf/MMBTU; and
O_{2 correction factor} = (20.9%)/(20.9% – O_2 measured); where O_2 measured is percent oxygen on a dry basis.

(b) The owner or operator of the equipment or source operation adjusted pursuant to (a) above shall ensure that each adjustment is recorded in a log book or computer data system and retained for a minimum of five years, to be made readily accessible to the Department upon request. Such record shall contain the following information for each adjustment:

1. The date of the adjustment and the times at which it began and ended;
2. The name, title and affiliation of the person who made the adjustment;
3. The NO_X and CO concentrations in the effluent stream, in ppmvd, before and after each actual adjustment was made;
4. The concentration of O₂ (in percent dry basis) at which the CO and NO_X concentrations were measured pursuant to (a)5 above;
5. A description of any corrective action taken;
6. Results from any subsequent tests performed after taking any corrective action, including concentrations and converted emission values in pounds per million BTU (lb/MMBTU);
7. The type and amount of fuel used over the 12 months prior to the annual adjustment; and
8. Any other information which the Department or the EPA has required as a condition of approval of any permit or certificate issued for the equipment or source operation.

(c) The owner or operator shall ensure that an annual adjustment combustion process report is submitted electronically to the Department according to the schedule listed in (d) below, and in the format the Department specifies at its website. The report shall contain the following information:

1. The concentrations of NO_X and CO in the effluent stream in ppmvd, and O₂ in percent dry basis, measured before and after the adjustment of the combustion process pursuant to (a)5 above;
2. The converted emission values in lb/MMBTU for the measurements taken before and after the adjustment of the combustion process;
3. A description of any corrective actions taken as a part of the combustion adjustment; and
4. The type and amount of fuel used over the 12 months prior to the annual adjustment.

(d) The owner or operator of an industrial/commercial/institutional boiler or other indirect heat exchanger shall ensure that the annual adjustment combustion process report required in (c) above is submitted to the Department within 45 days after the adjustment of the combustion process is completed, based on the gross heat input of the boiler or heat exchanger as follows:

1. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least five million but less than 10 million BTU per hour, beginning in 2012;
2. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least 10 million but less than 20 million BTU per hour, beginning in 2010; and
3. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input rate of at least 20 million BTU per hour or greater, beginning in 2009;

(e) The owner or operator of the adjusted equipment or source operation shall ensure that the operating parameter settings are established and recorded after the combustion process is adjusted and that the adjusted equipment or source operation is maintained to operate consistent with the annual adjustment.

(f) An exceedance of an emission limit that occurs during an adjustment of the combustion process under (a) above or (g) below is not a violation of this subchapter if it occurs as a result of the adjustment. After the combustion adjustment has been completed, the maximum emission rate of any contaminant shall not exceed the maximum allowable emission rate applicable under this subchapter or under an operating permit issued pursuant to N.J.A.C. 7:27-22 or an applicable certificate issued pursuant to N.J.A.C. 7:27-8.

Electronic Submittal Instructions

Following is a brief list of the steps necessary to electronically submit an annual combustion adjustment report.  Detailed instructions can be found in the “How To Submit” document.

Step A: You must obtain a MyNJ account, if you do not already have one.

Step B: You must obtain an NJ DEP Online user ID, if you do not already have one.

See NJ DEP Online instructions for more details on steps A & B.  You only need to complete steps A & B once. 

Steps 1 and 2: Create a NOx RACT Combustion Adjustment service in NJ DEP Online, and select your facility.

Step 3: Add contact information to the service.

Step 4: Select the boiler(s) (and/or other equipment) that were adjusted from the list of available equipment, taken from your existing air pollution control permits.

Step 5: Enter the required adjustment data for each piece of equipment selected in Step 4.

Step 6: Certify the submittal.  Upon certification, the NOx RACT Combustion Adjustment is automatically submitted and you will be able to print a copy for yourself.

See How To Submit a NOx RACT Combustion Adjustment Report for more details on steps 1 -6. You will need to complete steps 1 – 6 each calendar year.
