RELATES TO: KRS Chapter 224
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.

CO
2 Percentage.
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.
