Current through Register Vol. 50, No. 9, March 1, 2024
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 for the control of emissions from new blast furnace
casthouses.
Section 1. Applicability.
The provisions of this administrative regulation shall apply to blast furnace
casthouses commenced on or after 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) "Blast
furnace casthouses" means the building or buildings which houses the following
operations:
(a) Casting of hot metal from a
blast furnace from an opening at the bottom of the furnace through a runner
into a torpedo car; and
(b) Casting
of the slag from a blast furnace from an opening at the bottom of the furnace
through runner(s) into a slag ladle or slag pit.
(2) "Blast furnace" means a furnace producing
pig iron by introducing iron-bearing materials, coke, and flux materials into a
vessel and introducing heated combustion air to form a reducing gas which is
passed counter current to the descending raw materials.
(3) "Classification date" means the effective
date of this administrative regulation.
(4) "Control device" means the air pollution
control equipment used to remove particulate matter generated in the blast
furnace casthouses from the effluent gas stream.
Section 3. Standard for Particulate Matter.
No owner or operator of a blast furnace casthouse subject to the provisions of
this administrative regulation shall cause to be discharged into the atmosphere
from the blast furnace casthouse any gases which:
(1) Exhibit an average opacity in excess of
twenty (20) percent.
(2) If such
gases exit from a gas cleaner, no owner or operator subject to the provisions
of this administrative regulation shall cause to be discharged into the
atmosphere any gases which:
(a) Contain
particulate matter in excess of 0.010 gr/dscf as tested during pouring of hot
metal and slag; or
(b) Exhibit an
average opacity in excess of twenty (20) percent.
Section 4. Test Methods and
Procedures. Reference methods in Appendix A of 40 C.F.R. 60, except as provided
in
401 KAR 50:045,
and as supplemented by the procedures in subsection (6) of this section, shall
be used to determine compliance with the standards prescribed under Section 3
of this administrative regulation as follows:
(1) Reference Method 5 for the concentration
of particulate matter and associated moisture content;
(2) Reference Method 1 for sample and
velocity traverses;
(3) Reference
Method 2 for velocity and volumetric flow rate;
(4) Reference Method 3 for gas analysis;
and
(5) Reference Method 9 for the
determination of opacity.
(6) For
the purpose of determining compliance with Section 3(1) of this administrative
regulation, the following procedures shall be used to supplement Method 9:
(a) A series of consecutive observations
taken at fifteen (15) second intervals shall be made during the entire period
of time that hot metal and slag are being cast. Compliance shall be based on a
comparison of the standards in Section 3(1) of this administrative regulation
with the highest average opacity occurring over any six (6) consecutive minutes
during the period of observation. If emissions are being emitted from the roof
monitor and other discharge points from the building, the reader shall read and
record whichever plume is most opaque at the time of each reading.
(b)
1. In
making observations of roof monitor emissions, the reader shall be positioned
within a sector seventy (70) degrees either side of a line perpendicular to the
long axis of the roof monitor. Within this sector the reader shall be
positioned with the sun behind him and generally perpendicular to the axis of
the plume that is being observed. On overcast days or if the plume is in a
shadow, the reader need not follow the requirement about positioning his back
to the sun.
2. In making
observations of emissions from other openings in the building, the reader shall
be positioned within a sector seventy (70) degrees either side of a line
perpendicular to the side of the building nearest which the emissions occur and
with a clear view of the emissions. Within this sector the reader shall be
positioned with the sun behind him and generally perpendicular to the axis of
the plume that is being observed. On overcast days, the reader need not follow
the requirement about positioning his back to the sun.
Section 5. Variances.
The cabinet may grant a variance from the control requirements of this
administrative regulation. Requests for such a variance shall be supported by
adequate technical and economic documentation, provided that any alternative
strategy shall result in at least an equivalent overall reduction in
particulate emissions from the source as would be required by this
administrative regulation.
