Section 280.101
Preamble and Statutory Authority
a)
On September 6, 1979, the Pollution Control Board adopted a Final Order in its
regulatory proceeding R78-10 which amended its previously adopted particulate
emission limitations for steel manufacturing processes. Included in the R78-10
regulations are limitations of visible emissions from the following by-product coke plant
emission sources and/or operations:
Rule 203(d)(5)(B)(ii) -- charging operations
Rule 203(d)(5)(B)(iv) -- coke oven doors
Rule 203(d)(5)(B)(v) -- coke oven lids
Rule 203(d)(5)(B)(vi) -- coke oven offtake piping
b)
The regulations specify maximum time periods during which visible emissions are
permitted during charging operations and maximum percentages of doors, lids, and
offtake piping that are permitted to emit visible emissions. The purpose of this Rule is to
establish procedures by which observers are able to determine the compliance status of
by-product coke oven batteries subject to Rules 203(d)(5)(B)(ii), 203(d)(5)(B)(iv),
203(d)(5)(B)(v), and 203(d)(5)(B)(vi).

Topside: the top of a coke oven battery including, but not limited to, the charge ports and
charge port lids.
Section 280.103
Applicability
The procedures contained herein shall apply to all coke oven batteries located within the State of
Illinois. In evaluating visible emissions from coke oven batteries, observers shall take into
account all such emissions except emissions of water vapor and "mere wisps of smoke" which
have been specifically exempted by the Pollution Control Board, In the Matter of: Particulate
Emissions from Steel Mills, R78-10, Opinion of the Board at page 4 (January 10, 1980).
Section 280.104
Determination of Visible Emissions from Coke Oven Charging Operations
Compliance with the coke oven charging emission limitation contained in Rule 203(d)(5)(B)(ii)
of the Illinois Pollution Control Board Rules and Regulations, Chapter 2: Air Pollution shall be
determined by the following procedure:
a)
Observation Points.
Observations of charging emissions shall be made from any point or points on the topside
of a coke oven battery from which an observer can obtain an unobstructed view of the
charging operation.
b)
Observations.
The observer shall time the visible emissions with a stopwatch while observing the
charging operation. The observation shall commence as soon as coal begins to flow into
the oven and shall terminate when the last charge port lid has been replaced.
Simultaneous emissions from more than one emission point shall be timed and recorded
as one emission and shall not be added individually to the total time.
c)
Recording of Observations.
1)
The observer shall determine and record the total number of seconds that charging
emissions are visible during the charging of coal to the coke oven.
2)
For each charge observed, the observer shall record the total number of seconds
of visible emissions, the clock time for the initiation and completion of the
charging operation, and the battery identification and oven number.
3)
The observer shall not record any emissions observed after all charging port lids
have been firmly seated following removal of the larry car, such as emissions
occurring when a lid has been temporarily removed to permit spilled coal to be
swept into the oven. The observer shall also not record emissions from the end
oven on a coke oven battery which is unable to utilize a jumper pipe connection.
d)
Interruptions of Observations.
In the event that observations of emissions from a charge are interrupted or there has
been a malfunction in the charging operation, as defined by operating permits issued to
the owner or operator of the coke oven battery pursuant to Rule 105, the data from that
charge shall be invalidated and the observer shall note on his observation sheet the reason
for invalidating the data. The observer shall then resume observation of the next
consecutive charge or charges and continue until a set of five charges has been recorded.
e)
Compliance Determination.
Compliance with Rule 203(d)(5)(B)(ii) shall be determined by summing the seconds of
visible charging emissions observed during each of the five charges.
Section 280.105
Determination of Visible Emissions from Coke Oven Doors
Compliance with the coke oven door emission limitation contained in Rule 203(d)(5)(B)(iv) of
the Illinois Pollution Control Board Rules and Regulations, Chapter 2: Air Pollution shall be
determined by the following procedures:
a)
Observation Points.
Observations of coke oven door emissions shall be made from a safe point beyond the
clearance lines of the pusher and quench car where the observer can obtain an
unobstructed view of each coke oven door.
b)
Observations.
Each coke oven door shall be observed in sequence for only that period of time necessary
to determine whether or not, at that time, there are visible emissions from any point of the
coke oven door while the observer walks along the side of the battery. The observer shall
continue the procedure along the entire length of the battery on both sides.
c)
Recording of Observations.
The observer shall record the battery identification, battery side, and identification
number of each coke oven door emitting visible emissions.
d)
Obstruction of Observer's View.
Before completing the traverse, or immediately thereafter, the observer shall attempt to
reobserve the obstructed coke oven doors.
e)
Compliance Determination.
Compliance with Rule 203(d)(5)(B)(iv) shall be determined by utilizing the following
formula:
(# of coke oven doors on operating ovens with visible emissions)
------------------------------------ x 100 = 10% or less
(# of coke oven doors - (# of obstructed on operating ovens)coke oven doors)
Section 280.106
Determination of Visible Emissions from Charge Port Lids
Compliance with the charge port lid emission limitation contained in Rule 203(d)(5)(B)(v) of the
Illinois Pollution Control Board Rules and Regulations, Chapter 2: Air Pollution shall be
determined by the following procedure:
a)
Observations.
Observations of any visible emissions other than charging emissions from the charge port
lids shall be made and recorded during the period the observer walks the topside of a
battery from one end to the other one time. Each oven shall be observed in sequence.
b)
Recording of Observations.
The observer shall record the battery identification, the location of the lid emission on
each oven, and whether an oven was dampered off.
c)
Compliance Determination.
Compliance with Rule 203(d)(5)(B)(v) shall be determined by utilizing the following
formula:
(# of charging port lids on operating ovens with visible emissions)
------------------------------------- x 100 = 5% or less
(# number of charging port lids on operating ovens)
Section 280.107
Determination of Visible Emissions from Offtake Piping
Compliance with the offtake piping emission limitation contained in Rule 203(d)(5)(B)(vi) of the
Illinois Pollution Control Board Rules and Regulations, Chapter 2: Air Pollutions shall be
determined by the following procedure:
a)
Observations.
Observations of any visible emissions from the offtake piping shall be made by traversing
the topside of the battery near the centerline one time. During the traverse, the observer
may stray from the centerline and walk as close as possible to the offtake piping in order
to determine whether an observed emission is coming from the offtake piping. Each
oven shall be observed in sequence.
b)
Recording of Observations.
The observer shall record the battery identification, the points of offtake piping emission
from any oven, and the oven number.
c)
Compliance Determination.
Compliance with Rule 203(d)(5)(B)(vi) shall be determined by utilizing the following
formula:
(# of offtake pipes on operating ovens with visible emissions)
------------------------------------ x 100 = 10% or less
(# of offtake pipes on operating ovens)
