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 control of emissions from steel plants using existing
basic oxygen process furnaces.
Section
1. Applicability. Provisions of this administrative regulation are
applicable to the following affected facilities commenced before the
classification date defined below: basic oxygen process furnaces, associated
metallurgical equipment, and dust-handling equipment.
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) "Basic
oxygen process furnaces (BOPF)" means any furnace producing steel by charging
scrap steel, hot metal and flux materials into a vessel and introducing a high
volume of an oxygen-rich gas.
(2)
"Dust-handling equipment" means any equipment used to handle particulate matter
collected by a control device for a BOPF and/or associated equipment subject to
this administrative regulation.
(3)
"Control device" means the air pollution control equipment used to remove from
the effluent gas stream, particulate matter generated by a BOPF and/or
associated equipment.
(4) "Steel
production cycle" means the operations required to produce each batch of steel
and includes the following major functions: scrap preheating, scrap charging,
hot metal charging, oxygen blowing, dumping slag and tapping.
(5) "Charge" means the addition of steel
scrap, molten iron and other materials into a BOPF.
(6) "Tap" means the pouring of molten steel
from a BOPF.
(7) "Shop" means the
building or bay which houses one (1) or more BOPFs and associated metallurgical
equipment.
(8) "Classification
date" means June 11, 1973.
(9)
"Associated metallurgical equipment" means process equipment located in the
shop used in conjunction with external desulfurization of molten iron, hot
metal transfer, and transfer of slag and kish.
Section 3. Standard for Particulate Matter.
(1) No owner or operator subject to the
provisions of this administrative regulation shall cause to be discharged into
the atmosphere any gases which exceed a maximum particulate concentration of
0.030 gr/dscf from the control device associated with the BOPF as measured only
during the main oxygen blowing period.
(2) No owner or operator shall cause to be
discharged into the atmosphere any gases which exceed a maximum particulate
concentration of 0.010 gr/dscf from a control device associated with any other
BOPF associated metallurgical equipment as measured only during operation of
such equipment.
(3) No owner or
operator shall cause to be discharged into the atmosphere any gases which exit
from a control device and exhibit an opacity of twenty (20) percent or
more.
(4) No owner or operator
shall cause to be discharged into the atmosphere any gases which exit from a
shop, due to operations of a BOPF and/or associated metallurgical equipment,
and exhibit opacity of twenty (20) percent or more for more than eleven (11)
times as observed at fifteen (15) second intervals over a period of any sixty
(60) consecutive minutes. Reference Method 9 of Appendix A to 40 CFR 60, filed
by reference in
401 KAR
50:015 and supplemented by the procedures in Section
5(4) of this administrative regulation, shall be used for determining opacity
in this subsection, except for averaging time and number of
observations.
(5) No owner or
operator subject to the provisions of this administrative regulation shall
cause to be discharged into the atmosphere from dust-handling equipment any
gases which exhibit ten (10) percent opacity or greater.
Section 4. Monitoring of Operations. The
owner or operator of an affected facility shall maintain a single
time-measuring instrument which shall be used in recording daily the time and
duration of each steel production cycle, and the time and duration of any
diversion of exhaust gases from the main stack servicing the BOPF.
Section 5. Test Methods and Procedures.
(1) Reference methods in Appendix A of 40 CFR
60, except as provided under
401 KAR 50:045,
shall be used to determine compliance with the standards prescribed under
Section 3 of this administrative regulation as follows:
(a) Reference Method 5 for the concentration
of particulate matter and associated moisture content;
(b) Reference Method 1 for sample and
velocity traverses;
(c) Reference
Method 2 for velocity and volumetric flow rate;
(d) Reference Method 3 for gas analysis;
and
(e) Reference Method 9 for
opacity determination for emissions discharged through a control device and
from dust-handling equipment. For the purpose of this administrative
regulation, opacity observation taken at fifteen (15) second intervals
immediately before and after a diversion of exhaust gases from the control
device stack may be considered to be consecutive for the purpose of computing
an average opacity for a six (6) minute period. Observations taken during a
diversion shall not be used in determining compliance with the opacity
standard.
(2) For
Reference Method 5, the sampling for each run shall continue for an integral
number of cycles with total duration of at least sixty (60) minutes except that
shorter sampling times when necessitated by process variables or other factors
may be approved by the cabinet. The sampling rate shall be at least nine-tenths
(0.9) dscm/hr (0.53 dscf/min). For the purpose of testing the control device
associated with the BOPF a cycle shall start at the beginning of the primary
oxygen blow and shall terminate at the end of the primary oxygen
blow.
(3) Sampling of flue gases
during each steel production cycle shall be discontinued whenever all flue
gases are diverted from the stack and shall be resumed after each diversion
period.
(4) For the purpose of
determining opacity from a shop pursuant to Section 3(4) of this administrative
regulation, the following procedures shall be used to supplement Method 9:
(a) 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.
(b) 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.
(c) If emissions are being emitted from the
roof monitor and other discharge points from the building, the reader shall
read whichever plume is most opaque at the time of each reading.
Section 6. Compliance
Timetable. The owner or operator of an affected facility shall demonstrate
compliance with Section 3(1) of this administrative regulation on or before
December 31, 1982. Compliance with all other provisions of this administrative
regulation shall have been demonstrated on or before June 6, 1979.
Section 7. 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.
