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 existing blast furnace
casthouses.
Section 1. Applicability.
The provisions of this administrative regulation shall apply to blast furnace
casthouses located in, or impacting upon, an area designated nonattainment for
total suspended particulates under
401 KAR
51:010 which commenced before the classification date
defined below. Blast furnace casthouses located in areas designated as
nonattainment which were required to obtain permits prior to April 14, 1988
shall maintain the permit and any applicable requirements when the area is
redesignated in
401 KAR
51:010 or
40 CFR
81.318, unless a state implementation plan
which provides for other controls is approved by the U.S. EPA.
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 April 1,
1984.
(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 the casting 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 CFR 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 standard 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. Compliance
Timetable. The owner or operator of a blast furnace casthouse subject to the
provisions of this administrative regulation shall demonstrate compliance with
Section 3 of this administrative regulation on or before December 31,
1982.
Section 6. Alternate Emission
Limitations. The owner or operator of an affected facility subject to this
administrative regulation may propose an alternate plan pursuant to the
requirements of 401 KAR 51:055 to meet the emissions limitations required by
this administrative regulation.
