401 KAR 61:010. Existing incinerators.

 

      RELATES TO: KRS Chapter 224

      STATUTORY AUTHORITY: KRS 224.10-100

      NECESSITY, FUNCTION, AND CONFORMITY: KRS 224.10-100 requires the Environmental and Public Protection Cabinet to prescribe administrative regulations for the prevention, abatement, and control of air pollution. This administrative regulation provides standards of performance for existing incinerators.

 

      Section 1. Applicability. The provisions of this administrative regulation shall apply to each affected facility which means each incinerator with a capacity of two and five-tenths (2.5) cubic feet or greater commenced before the classification date defined below.

 

      Section 2. Definitions. As used in this administrative regulation, all terms not defined herein shall have the meaning given them in 401 KAR 50:010.

      (1) "Incinerator" means any furnace and appurtenances thereto used in the process of burning waste for the primary purpose of removing the combustible matter from the waste.

      (2) "Auxiliary fuel" means a substance burned in an incinerator to supply additional heat to attain temperature sufficiently high to dry and ignite the waste and to maintain ignition of the waste.

      (3) "Classification date" means:

      (a) August 17, 1971 for incinerators with a charging rate of more than fifty (50) tons/day.

      (b) April 9, 1972 for incinerators with a charging rate of fifty (50) tons/day or less.

 

      Section 3. Standard for Particulate Matter. (1) No person shall cause, suffer, allow, or permit the emission produced by the incineration of any substance other than sawdust, wood chips, or bark which:

      (a) Is greater than twenty (20) percent opacity; or

      (b) For those incinerators with charging rate greater than or equal to 500 lb/hr, exceeds two-tenths (0.20) grains of particulate matter per standard cubic foot of dry flue gas corrected to twelve (12) percent carbon dioxide excluding the contribution of carbon dioxide from auxiliary fuel.

      (2) No person shall cause, suffer, allow, or permit the emission produced by the incineration of sawdust, wood chips, or bark which:

      (a) Is equal to or greater than forty (40) percent opacity (for the purposes of 401 KAR 50:055, Section 2(4) and (5), thirty (30) consecutive minutes shall be allowed for start-up and thirty (30) consecutive minutes shall be allowed for shutdown); or

      (b) Exceeds 0.21 grains of particulate matter per standard cubic foot of dry flue gas corrected to twelve (12) percent carbon dioxide excluding the contribution of carbon dioxide from auxiliary fuel.

 

      Section 4. Monitoring of Operations. The owner or operator of any incinerator of more than forty-five (45) metric tons per day charging rate (fifty (50) tons per day) subject to the provisions of this administrative regulation shall record the daily charging rates and hours of operation.

 

      Section 5. Test Methods and Procedures. (1) Except as provided in 401 KAR 50:045, performance tests used to demonstrate compliance with Section 3 of this administrative regulation shall be conducted according to the following methods, (filed by reference in 401 KAR 50:015):

      (a) Kentucky Method 50 for the concentration of particulate matter and the associated moisture content;

      (b) Reference Method 1 for sample and velocity traverses;

      (c) Reference Method 2 for velocity and volumetric flow rate; and

      (d) Reference Method 3 for gas analysis and calculation of excess air using the integrated sample technique.

      (2) For Kentucky Method 50 the sampling time for each run shall be at least sixty (60) minutes and the minimum sample volume shall be 0.85 dscm (thirty (30.0) dscf) except that smaller sampling times or sample volumes, when necessitated by process variables or other factors, may be approved by the cabinet.

      (3) If a wet scrubber is used, the gas analysis sample shall reflect flue gas conditions after the scrubber, allowing for carbon dioxide absorption by sampling the gas on the scrubber inlet and outlet sides according to either the procedure under paragraphs (a) to (c) of this subsection or the procedure under paragraphs (a), (b) and (f) of this subsection as follows:

      (a) The outlet sampling site shall be the same as for the particulate matter measurement. The inlet site shall be selected according to Reference Method 1, or as specified by the cabinet.

      (b) Randomly select nine (9) sampling points within the cross section at both the inlet and outlet sampling sites. Use the first set of three (3) for the first run, the second set for the second run, and the third set for the third run.

      (c) Simultaneously with each particulate matter run, extract and analyze for CO2 an integrated gas sample according to Reference Method 3, traversing the three (3) sample points and sampling at each point for equal increments of time. Conduct the runs at both inlet and outlet sampling sites.

      (d) Measure the volumetric flow rate at the inlet during each particulate matter run according to Reference Method 2, using the full number of traverse points. For the inlet make two (2) full velocity traverses approximately one (1) hour apart during each run and average the results. The outlet volumetric flow rate may be determined from the particulate matter run (Reference Method 5).

      (e) Calculate the adjusted CO2 percentage using the equation in Appendix A to this administrative regulation.

      (f) Alternatively, the following procedures may be substituted for the procedures under paragraphs (c), (d) and (e) of this subsection:

      1. Simultaneously with each particulate matter run, extract and analyze for carbon dioxide, oxygen and nitrogen an integrated gas sample according to Reference Method 3, traversing the three (3) sample points and sampling for equal increments of time at each point. Conduct the runs at both the inlet and outlet sampling sites.

      2. After completing the analysis of the gas sample, calculate the percentage of excess air (% EA) for both the inlet and outlet sampling sites using Equation 3-1 in Reference Method 3.

      3. Calculate the adjusted CO2 percentage using the equation in Appendix B to this administrative regulation.

      4. Particulate matter emissions expressed in g/dscm, shall be corrected to twelve (12) percent CO2 by using the equation in Appendix C to this administrative regulation. (5 Ky.R. 469; eff. 6-6-1979; TAm eff. 8-9-2007.)

 

APPENDIX A TO 401 KAR 61:010

EQUATION FOR ADJUSTED CO2 PERCENTAGE

 

(% CO2)adj = (% CO2)di (Qdi/Qdo)

Where:

      (% CO2)adj is the adjusted CO2 percentage which removed the effect of CO2 absorption and diffusion of air;

      (% CO2)di is the percentage of CO2 measured before the scrubber, dry basis;

      Qdi is the volumetric flow rate before the scrubber, average of 2 runs, dscf/min, using Reference Method 2; and

      Qdo is the volumetric flow rate after the scrubber, dscf/min, using Reference Methods 2 and 5.

 

APPENDIX B TO 401 KAR 61:010

EQUATION FOR ADJUSTED CO2 PERCENTAGE

 

Where:

      (% CO2)adj is the adjusted outlet CO2 percentage;

      (% CO2)di is the percentage of CO2 measured before the scrubber, dry basis;

      (% EA)i is the percentage of excess air at the inlet; and

      (% EA)o is the percentage of excess air at the outlet.

 

APPENDIX C TO 401 KAR 61:010

EQUATION FOR CORRECTING

PARTICULATE MATTER EMISSIONS

 

Where:

      C12 is the concentration of particulate matter corrected to 12 percent CO2;

      c is the concentration of particulate matter as measured by Reference Method 5;

      % CO2 is the percentage of CO2 as measured by Reference Method 3, or when applicable, the adjusted outlet CO2 percentage as determined by Section 5(3)(c) of this administrative regulation.
