Current through Register Vol. 56, No. 19, October 7, 2024

Section 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 NOx and CO consistent with the manufacturer's specifications;

5. Measure the concentrations in the effluent stream of NO and CO in ppmvd, and O in percent, before and after the adjustment is made; and

6. Convert the emission values of the NO and CO concentrations measured pursuant to (a)5 above to pounds per million BTU (lb/MM BTU) according to the following formula:

lb/MM BTU = ppmvd x MW x F dry factor x O 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; CO = 28 lb/lb-mole

F dry factor for:

Natural gas = 8,710 dscf/MM BTU

Residual or fuel oil = 9,190 dscf/MM BTU

O[2] correction factor: (20.9%) (20.9% - O[2] measured)

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 NOx and CO concentrations in the effluent stream, in ppmvd, before and after each actual adjustment was made;

4. The concentration of O[2] (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/MM BTU);

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 NOx 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/MM BTU 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;

3. For an industrial/commercial/institutional boiler or other indirect heat exchanger with a maximum gross heat input of rate 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.

(g) The owner or operator of a stationary combustion turbine or reciprocating engine shall ensure that the adjustment of the combustion process is carried out according to the manufacturer's recommended procedures and maintenance schedules.

(h) The owner or operator of a stationary combustion turbine or reciprocating engine adjusted pursuant to (g) 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 performed the procedure and adjustment;

3. The type of procedure and maintenance performed;

4. The concentrations of NOx CO and O2, measured before and after the adjustment was made; and

5. The type and amount of fuel use over the 12 months prior to the adjustment.
