I. INTRODUCTION
During the week of July 25 to 30, 1977, a team of inspectors
from the Environmental Protection Agency (EPA) Division of Stationary
Source Enforcement (DSSE), Office of Air Quality Planning and Standards
(OAQPS), and the National Enforcement Investigations Center (NEIC)
conducted an extensive survey of visible emissions and process opera-
tions at the CF&I Steel Corporation coke plant at Pueblo, Colorado.
The survey was designed to fulfill the following objectives.
1. Acquire a visible emissions data base at Battery B for use
in establishing new source performance or hazardous air
pollutant standards (NSPS or NESHAPS) for charging.
2. Acquire visible emissions and process operations data for
the national coke battery evaluation program.
3. Determine if Batteries B, C and D were in compliance with
the Colorado Air Pollution Control Commission Regulation
l-I.A1 for charging, pushing, door, and topside emissions.
The Emission Standards and Engineering Division (ESED) of the
Office of Air Quality Planning and Standards is in the process of
developing charging and other performance standards for coke plants.
NEIC personnel determined during a February 14 to 15, 1977 reconnais-
sance inspection of the CF&I coke plant that it was a suitable plant
1
for gathering data for a charging standard. ESED was informed of
the NEIC reconnaissance inspection findings and requested to partici-
pate in a survey to gather charging data.
-------
2
Interest in the CF&I coke plant, however, extended beyond ESEDs
desire to gather charging data. DSSE, NEIC, EPA Region III, and to a
limited degree OAQPS, were involved in a national coke battery evaluation.
It was believed that data gathered at CF&I would be a useful addition to
the programs data base. An explanation of the national coke battery
evaluation program, including its objectives and history can be found
2
in the Fairfield report.
The compliance determination for the coke plant was done at the
request of the Region VIII Office of EPA. Since 1974, CF&I had been the
subject of compliance investigations by EPA. A history of these investi-
gations, as well as of the associated litigation, can be found in the
1
reconnaissance report.
All data concerning compliance with Regulation l-I.A.l was trans-
mitted to the Regional Office shortly after survey completion and, thus,
will not be discussed in this report.
This report presents the results of visible emissions and process
observations made at CF&I. It contains tables and figures which have
been developed from the field data for use in further data analysis,
regulation development, and enforcement case development. Some correla-
tion of parameters (cause/effect) are also contained in this report.
For ease of reading the text of the report, major tables have
been placed in Appendix A and all figures in Appendix B.

Comparisons were made between process data and VEO data gathered
for charging, pushing and doors to determine if cause/effect relation-
ships existed.
In the case of larry car alignment and standpipe blockage, there
was reasonably good correlation between the process observations and
VEO data. For the few cases where the observers detected significant
procedural errors, or standpipe blockage, the visible emissions were
higher than the average.
In the case of aspiration steam pressure, chuck door operation,
and offtake opacity, a large amount of data was gathered, but there
was not the anticipated correlation between the process and VEO data.
Studies have shown that approximately 7.7 kg/cm 2 (110 psig) is needed
at the nozzle for a double collector main to provide sufficient aspira-
tion to 4.3 m (14 ft) ovens. The lowest aspiration steam pressure
observed during charging was 8.4 kg/cm 2 (120 psig), measured at topside
level downstream from the ovens being charged. Although the 8.4 kg/cm 2
aspiration pressure at CF&Is coke plant was not measured at the nozzle,
this steam pressure was adequate for oven aspiration, as evidenced by
the low emission rates during charging. Since the aspiration steam
pressure was not observed to drop below that needed for sufficient
aspiration (7.7 kg/cm 2 ), one should not expect a direct correlation
between steam pressure and charging emissions.
The amount of time chuck doors were left open during charging
prior to the leveling bar entering the oven varied from five to fif-
teen seconds. There was no direct or indirect relationship between
these times and charging emissions. This indicates either that there
is sufficient aspiration to maintain a negative pressure in the oven
or that the loss of aspiration from the chuck door being opened prior
to the entry of the leveling bar may not be significant enough to
affect charging emissions--at least for the time intervals recorded
at CF&I.
-------
6
Offtake opacity observations were evaluated to determine if a
relationship existed between high opacity (>50% opacity was selected
as the criterion) occurring when the standpipe caps were raised prior
to a push and higher-than-average pushing emissions. No such rela-
tionship was seen.
Observer comments made during charging observations were useful
in determining reasons for emissions in excess of the average. In fact,
these explained four of the five charges that had emissions in excess
of twice the daily average.
A large amount of door damage and cleaning data was gathered during
the survey; however, no apparent correlation existed between door damage
and deposits, and door leaks. A possible reason for the poor correlation
could be the subjective nature of evaluating door deposits and damage.
Collector main pressure never exceeded 12 mm of water except in-
stantaneously. However, the pressure fluctuated up to 5 mm of water
during the day on the cokeside--a possible explanation for the consis-
tently higher incidence of cokeside door leaks and the poor correlation
between door damage and deposits, and door leaks.

III. PROCESS DESCRIPTION
CF&I Steel Corporation operates a three-battery coke plant at
Pueblo, Colorado [ Figure 1-Appendix B]. The batteries are designated
as B, C, and D, and have 65, 47, and 31 ovens, respectively. The
three batteries are operated as two units (B as one and C and D as
another) with no distinct physical demarcation between the two opera-
ting units.* Each unit has its own coal bunker, larry car, cokeside
door machine, quench car and pusher machine with leveling bar. All
three batteries are equipped with double collector mains and are gun-
fired.
B Battery is divided into three sections (A:l-23, B:l-23, and
C:l19); C Battery is divided into two sections (E:l-23 and F:l-24);
and D Battery is not subdivided. All ovens are pushed and charged by
the Marquard system (A7, B-7, C-7, A-9, 8-9, C-9, A-il, etc.).
Each oven has an overall length of 13.2
length inside the doors of 12.4 m (40.5 ft).

CF&I officials report that the coal volume distribution between
larry car hoppers and the charging sequence were designed to provide
a 30.5 cm (12 in) free space in the oven after leveling. To obtain
this gas channel the hopper volumes were set as follows:

Hopper volumes are regulated by volumetric rings during loading;
these rings are seldom adjusted to compensate for changes in coal
flow properties.
ThE typical charging sequence presently employed at CF&I was
originally instituted in May 1973 on Battery B and is now used on all
three batteries. Modifications to the sequence have been made from
time to time thereafter. The sequence begins when the Koppers-designed-
and-constructed larry car is loaded at the coal bunkers to the desired
hopper loadings as permitted by the volumetric rings. The loaded car
travels to the oven to be charged and is spotted so that the platforms
on the north end of the larry car are lined with the open standpipe
caps of the oven to be charged. The larry car operator then cleans
the gooseneck of the oven to be charged, closes the standpipe cap,
* Each oven has four charge ports and four corresponding hoppers in
the larry car numbered from pusher to cokeside.

taps the cap down to seal it properly, and seals the cap with luting
material.* The larry car is then positioned over the oven charge
ports and dropsleeves are lowered into position. When the pusher
machine is in position to level the oven, the aspiration steam valve
is opened and the dampers to the collector main are opened. The larry
car operator then pushes one button and the charge proceeds as follows:
1. The coal is charged simultaneously from #2 hopper for 16
seconds and from #3 hopper for 11 seconds and the feeders
shut off, leaving these two hoppers less than full. This
practice was instituted in August 1976.
2. The #1 and #4 hoppers are emptied simultaneously with #1
being emptied about 10 seconds ahead of #4. The slide gates
close automatically when the amperage on the screw feed
drive motors goes to zero. The operator raises the dropsleeves
mechanically and replaces the lids mechanically with the
magnetic lid lifters one at a time as the hoppers go empty;
the cycle cannot continue until this is done by the operator
(larryman). This practice, adopted in February 1977 takes
about 100 seconds.
3. After #1 and #4 lids are replaced, #2 hopper is emptied,
the dropsleeve is raised, and the lid is replaced. This
requires about 38 seconds.
4. A signal horn automatically notifies the pusherman to open
the chuck door and start leveling the coal when the #2 charge
port lid is replaced. (The pusher machine is also Koppers
designed and constructed.)
* At the time of the survey the lidman and larryman were using fine
coal in an attempt to seal charge port lids and standpipe caps.
As of April 1978 CF & I reports they began to use a luting compound
to seal leaks.
-------

5. While the pusherman is leveling the coal in the oven, the
#3 hopper is emptied in a start-stop manner - run 11 seconds,
down 4 seconds, run 8 seconds, down 4 seconds, run 4 seconds,
down 4 seconds. This 4 - 4 run-stop continues until the
hopper is emptied, at which time the slide gate is closed,
the dropsleeve is raised, and the lid is replaced. This
practice was developed during the period June to September
1976.
6. The leveling bar makes one more stroke after #3 hopper is
emptied and is withdrawn, and the chuck door is closed.
7. When the charge is complete (the dropsleeves raised, the
lids replaced, the leveling bar withdrawn, and the chuck
door closed), the lidinan seats the charge port lids, attempts
to seal them,* and turns the aspiration steam off at both
ends.
8. The larryman, upon finishing the charge, moves to the oven
which has just been pushed two ovens away and simultaneously
mechanically removes the charge port lids and mechanically
cleans the goosenecks with a pair of reamers. At his discre-
tion, the larryman may also manually clean the standpipes
and/or caps with a chisel-headed steel bar.
On Battery B, pushes are three ovens ahead in the sequence (i.e.,,
when B-8 is pushed, B-6 will be charged, and A-8 and C-6 are both
empty); whereas on Battery C pushes are only two ovens ahead in the
sequence, and on Battery D, pushes are only one oven ahead in sequence.
This allows three ovens on Battery B, two ovens on Battery C, and one
oven on Battery 0 to decarbonize at a time.
* At the time of the survey the lidman and larryman were using fine
coal in an attempt to seal charge port lids and standpipe caps.
As of April 1978 CF & I reports they began to use a luting compound
to seal leaks.
-------
11
The leveling bar is equipped with a smoke boot that is designed
to provide a seal between the leveling bar and the chuck door jamb
during the time the leveling bar is in the oven.
The main header pipe for the charging steam aspiration system
comes into the batteries at the south end of Battery B. From there
it is split into two header pipes which run along the pusher and coke
sides of all three batteries. Each header pipe feeds the aspiration
steam nozzles which on Batteries B, C, and the cokeside of D are located
atop the gooseneck pointed directly downward into the collector main.
On the push side of Battery 0 the steam nozzle is located a few inches
below the front of the standpipe opening pointed into the gooseneck.
The steam nozzles used are multiport self-cleaning nozzles constructed
of stainless steel. Each nozzle contains six openings, the midpoints
of which are on a concentric circle. Each opening is 0.79 cm diameter
(5/16 in) and angles outward at 30 degrees.
The principal gauge to measure header steam pressure is located
on the south end of Battery B at the bench level. The steam is satura-
ted and regulated to a nominal pressure of 9.1 kg/cm 2 (130 psi). Two
additional steam gauges are located at the catwalk level of Battery
C. The pusher side gauges is behind the standpipe for oven E-13; the
cokeside gauge is between the standpipes for ovens E-l1 and E-l2.

IV. SURVEY PROCEDURES
PERSONNEL PLACEMENT
At the start of each day, the designated team leader handed to
the CF&I contact a copy of a completed personnel placement form which
indicated by name each inspectors observation position and task for
that day, either as a visible emissions observer or a process observer.
The Company could then assign, at its discretion, the appropriate
number of guides for the EPA inspectors. Normally the inspection
team consisted of three visible emissions observers reading charging
on Battery B (Method B); one visible emissions observer reading charging
on Battery C-D (Method A); one visible emissions observer reading
door leaks and topside leaks on Batteries B and C-D (Methods C and
H); a team leader who was the Company contact for the day and overall
supervisor; two inspectors who made process observations from the
catwalk on Battery B; a larry car inspector who made process observa-
tions from the larry car on Battery B; a pusher machine inspector on
Battery B; and a cokeside door machine inspector on Battery B.
VISIBLE EMISSIONS OBSERVATION PROCEDURES
The seven visible emissions observation methods used in the CF&I
survey are briefly described below. A complete description of each
method and the forms used are contained in Appendix C.
Charging
Observation Methods A and B were used to read charging emissions.
For Method A, the inspector timed the number of seconds of visible
-------
13
emissions >20% opacity during the charge period.* The inspector also
recorded the maximum opacity during the charge period. For Method B
the inspectors timed the number of seconds of any visible emissions
during the charge period; Method B is essentially the same as the
proposed EPA Method 112 for charging. In all cases, the inspectors
were positioned about eight to ten ovens north of the larry car.
Doors
Method C was the door emissions observation method used at CF&I.
Battery I) was read as one unit and Battery C-D as another. The in-
spector began at either end of the battery on either the pusher side
or cokeside and walked along a line parallel with the battery a safe
distance outside the pusher machine or hot car tracks. As the inspector
walked, he paused to record which doors leaked and to record two opacity
observations--one at the lintel and the other at the point of emission.
After the inspector completed his traverse along one side of th battery
he proceeded to the other side and made a similar traverse.
Tops ides
Topsides inspectors used Method H as the observation method to
determine standpipe and lid leaks. Method H is, with minor exceptions,
identical to the proposed EPA Method 112 for topsides. The inspector
began at either end of the battery and walked along the center of the
battery top. In one direction he recorded lid leaks and in the other
traverse he recorded standpipe leaks. The inspector usually observed
standpipe leaks in the direction where the sun was at his back.
* The charge period begins when coal is first introduced into an oven
and ends when the last charge port lid is replaced.
-------
14
Pushing
Observation Methods D and F were used to read pushing emissions
during the CF&I survey. For each method, the inspector located himself
on the cokeside of the battery outside the hot car tracks to obtain a
clear view of the push. For Method D, the inspector timed the number
of seconds of visible emissions >20% during the push cycle* and the
maximum opacity during the push.** For Method F, another inspector
made a Method 9-like observation of opacity each 15 seconds, except
during the push when observations were made every 5 seconds.
PROCESS OBSERVATION PROCEDURES
Daily the team leader went to the reversing room at Battery B to
initial and record the time and date on the offtake pressure, stack
draft pressure, and waste heat flue temperature charts.
The team leader was also responsible to maintain the photography
log for the movies and/or still shots that were taken. The approximate
footage of movie film and the number of still shots were logged, as
well as the subject of the photography.
The remaining process operations observed and the observation
procedures are discussed in the context of the emission source (charging,
doors, topsides, and pushing) for which the process parameter is of
some consequence. The purpose for collecting these data and the pro-
cedures used are discussed in the Fairfield report. 2 The forms used
in the CF&I survey are contained in Appendix 0.
* The push cycle begins when the cokeside door is removed and ends
when the quench occurs.
** The push begins when the coke in the oven starts to move toward the
hot car and ends when all the coke is in the hot car.
-------
15
Charging
The visible emissions observers observing charging were asked to
make notations of larry car misalignment; i.e., if the larry car was not
positioned properly over the charge ports during charging. The team
leader checked oven port carbon several times during the survey and noted
his observations in a logbook.
During the survey, standpipes on Battery B were inspected by the
catwalk inspectors with the aid of a mirror. The inspectors diagrammed
the standpipe carbon buildup and indicated percent blockage. The larry
car inspectors noted whether goosenecks were cleaned. Both static (no
charging being conducted) and dynamic (during charging) steam pressures
at the standpipe gauges were recorded during charging aspiration on
Battery B by the catwalk inspectors. Those times the chuck door was open,
prior to the entry of the leveling bar, were documented by the pusher
machine inspector while charging emissions were being observed.
At EPAs request, each day Company workers collected three separate
samples of coal from the larry car hoppers. The time of the coal sample
collection was recorded by the larry car inspector. The Company per-
formed an analysis of the samples taken. The Company continued to
analyze the routine composite sample it obtained at various times during
the entire day from the belt which transfers coal from storage to the
coal bunker. The results of both analyses were provided to the team
leader after the survey.
Doors and Topsides
For ease in assessing door damage, the door was divided into six
sections for observations.* Both the cokeside door machine and pusher
* The six sections were the lintel (top), hearth (bottom) and upper and
lower right and left sides.
-------
16
machine inspector recorded the condition of the door on removal. The
inspectors recorded whether the knife edge and/or refractory were
damaged, with cracks, deformations, missing section, etc., whether
the gas channel contained carbon or heavy (viscous) tar deposits, and
whether any damaged door was replaced.
As with the door damage assessment, the door was divided into
six sections for observation of cleaning effectiveness. Both the
cokeside door machine and the pusher machine inspectors recorded the
extent of door and jamb cleaning and the extent of deposits remaining.
The pusher machine inspector also recorded similar information for
the chuck door. When the inspector could observe either door or jamb
cleaning, but not both, door cleaning was observed.
Collector main pressures were recorded on circular charts in the
reversing rooms. The team leader initialed the charts at least once
each day. Copies of the charts were provided by the Company after
the survey.
No data were gathered to characterize luting practices and sealing
times for either standpipe caps or lids.
Pushing
Prior to the time an oven is pushed, the standpipe cap is raised
and the lids are removed to begin a decarbonization period.* The catwalk
inspector recorded the offtake opacity at 15-second intervals for the
first minute after the standpipe cap was raised.
* The Company reported in a January 24, 1979 letter to EPA Region VII,
the oven is dampered off the main and the lids are removed
when the oven has been pushed.
-------
As the door was removed prior to pushing, the pusher machine in-
spector and the cokeside door machine inspector observed the coke
face and recorded whether it was smoking and/or flaming and to what
extent.

V. SURVEY RESULTS
VISIBLE EMISSIONS DATA
The data from visible emissions observations made during the
CF&I survey are presented in Tables 1 through 7 [ Appendix A] as follows:
Table 1. Method A - Charging Emissions Data
Table 2. Method B - Charging Emissions Data
Table 3. Method B - Charging Emissions Data for Five Consecutive
Charges
Table 4. Method C - Door Emissions Data
Table 5. Method H - Topsides Emissions Data
Table 6. Method D - Pushing Emissions Data
Table 7. Method F - Pushing Emissions Data
These data are discussed below and, where applicable, are compared
with the provisions of the July 19, 1978, EPA/CF&I consent decree. 3
The Method A results for Battery B [ Table 1] indicate that four
individual charges never exceeded 20% opacity, and only four exceeded
20% opacity for more than 10 seconds, and only one exceeded 20% opacity
for 20 seconds or more. The average daily emissions ranged from a
low of 2.0 seconds to a high of 10 seconds, although the latter average
is for only two readings. The overall average of all observations
was less than 4 seconds. However, Battery C-D did not perform as
well. Although five charges never exceeded 20% opacity, four exceeded
20% opacity for 20 seconds or more, and ten exceeded 20% opacity for
10 seconds. Since the high individual charges were dispersed over
three days, the average daily emissions ranged between 3.6 and 9.7
seconds. The overall average of all observations was less than 7
seconds.
-------
19
Method B was used only on Battery B. All charges were observed
by three inspectors. Only fourteen of ninety-two charges were observed
by at least one observer to exceed 10 seconds [ Table 2]; only five of
the ninety-two had averages of the three observers readings which
exceeded 10 seconds [ Table 3]. The average daily emissions ranged
from 4.2 to 6.3 seconds and the daily overall standard deviation never
exceeded 1.9 seconds [ Table 2]. As required by the consent decree,
the emissions from charging on Battery B never exceeded fifty-five
seconds for five consecutive charges; the highest sum of five was
47.3 seconds [ Table 3].
The consent decree requires that until July 1, 1979, visible
emissions may not be emitted from more than 10% of the total number
of observed operating doors plus three (i.e., 10% x operating doors +
3), considering each oven has but two doors. Since the total number
of doors for the batteries is 286{(65+47+31)x2], the consent decree
requires that <32 doors may leak. The survey results for door emissions
[ Table 4] were prepared prior to the establishment of the consent
decree provisions; thus, they were computed separately for Battery B
and Battery C-D. But, by adding the values in the column labelled %
Total Doors (2/Oven) for Battery B and Battery C-D for the same
date and consecutive stop times [ Table 4], an overall leak-rate
percentage can be computed. By comparing these computed leakrates
with the consent decree limit of 11.2% (32 + 286), it can be seen
that the CF & I coke plant was never in compliance with the door per-
formance standard of the consent decree during the survey [ Table 4].
The survey results for topsides emissions cannot be precisely
compared with the applicable provisions of the consent decree. The
consent decree allows for adjustments to the computation of offtake
system leakrate and lid leakrate for which the survey results do not
account. However, the survey results are probably conservative for
offtake system leakrate since ovens in the decarboriization period,
whether emitting visible emissions or not, were not counted as leaking,
-------
20
but were considered in the denominator of the percentage leakrate
calculation. The survey results for lids are probably higher than if
calculated by the consent decree method, because lids on the most
recently charged oven undoubtedly leaked and thus were considered in
both the numerator and denominator of the leakrate calculation. The
survey results for offtake system leakrate ranged from 0.0 to 24.6%
and 7.7 to 57.4% for the individual traverses on Batteries B and C-D,
respectively [ Table 5]. The consent decree allows for a 6% leakrate.
The survey results for lid leakrate ranged from 0.0 to 16.2% and 0.0
to 18.3% for the individual traverses on Batteries B and C-D, respect-
ively [ Table 5]. The consent decree allows for a 2% leakrate. The
consent decree provisions for offtake system and lid leakrate were
met one of eleven and four of eleven traverses, respectively, on Battery
B, and nine of fourteen and two of fourteen traverses, respectively, on
Battery C-U.
The Method U results for pus.hing emissions [ Table 6] indicate
that >20% opacity for the time period starting with pusher ram movement
and ending with the quench (the consent decree definition of the push)
was exceeded a range of 12 to 94 seconds for fifty-eight pushes on
Battery B and 20 to 63 seconds for thirteen pushes on Battery C_D.*
The Method F results [ Table 7] cannot be directly compared with the
consent decree provision that visible emissions from.., any uncaptured
pushing emissions shall not exceed 20% opacity at any time, measured
by EPA Method 9.... However, the average opacities for the two time
periods which comprise the consent decree definition of the push exceeded
the standard 61% of the time for thirty-five pushes on Battery B and
82% of the time for eleven pushes on Battery C-D.
* The consent decree requires that the pushing opacity limitation be
in effect on October 15, 1979.

PROCESS E)ATA
Process data [ Tables 8 through 13 - Appendix B] were obtained
during the survey to determine: (1) if a correlation between process
and VEO data could be shown; and (2) if any equipment malfunctions
(such as sudden loss of steam pressure) or procedural errors in operations
(such as failure to properly align the larry car) were responsible
for prolonged charging emissions. A discussion of the process findings
and any results of correlation are presented below.
Charging
Only three larry car misalignments were reported by visible emission
observer5. Four observers reported larry car misalignment on oven
A-7 on July 28, one observer reported a misalignment on oven A-21 and
two observers reported a misalignment on oven A-l2, both on July
29, as tabulated below. Also, an-observer noted that the larrycar
operator was given assistance with alignment on one other occasion.

These data, too few to be conclusive, indicate that larry car mis-
alignment contributes to charging emissions. The emissions from ovens
A-7 and A-12 were the highest for a single oven on July 28 and 29, re-
spectively. The emissions from A-21 were about the median value of all
July 29 charges. Supporting the possibility that the misalignnients
-------
22
associated with ovens A-7 and A-l2 (15.7 and 9.6 seconds of emissions) may
have been more severe than that for oven A-21 (4.7 seconds of emissions)
is the fact that more observers (4 and 2, respectively) reported A-7 and
A-l2 out of alignment than reported (1 observer) A-21 out of alignment.
Charge ports were examined several times during the survey by
the team leader, and in all cases the ports were at least 80% open.
Thus, free flow of coal from the larry car hoppers into the oven should
not have been impeded.
Three sets of peak and channel height* measurements were taken
during the survey. Peak heights were taken on Ports 1, 2 and 4 and
channel heights were taken on Port 3 [ Table 8]. In all cases the
channel height measurement exceeded the design free space of 30.5 cm
(12 in) after leveling. In no cases were the larry car hopper settings
revised after peak and channel height measurements. In addition,
roof carbon was checked several times by the team leader. No signifi-
cant roof carbon buildup (<20% of the channel space blocked) was
observed. Thus, there was an adequate free space for gases evolved
during the coking cycle to exhaust, to the offtake system, and subse-
quently to the by-products plant.
A list of all standpipes with 20% or greater blockage is contained
in Table 9. The percent blockage was estimated by the catwalk inspector.
A total of 33 standpipes were reported to have 20% or more of the
area blocked.
An oven with a standpipe <20% blocked has better than 90% of its
maximum air flow capability through that standpipe. 4 If the other
standpipe on that same oven is <20% blocked, then overall aspiration
* Peak and channel heights are defined as the distances between the top
of the coal and the roof of the oven before (for peak) and after (for
channel) leveling. They are measured by placing a measuring rod into
the charge ports.
-------
23
would be reduced by less than 10%. An oven with a standpipe 30% blocked
has between 80% and 85% of its maximum air flow capability. 4 If the
other standpipe on that same oven has any blockage, the overall aspira-
tion would be reduced by 10% or more.
Table 10 compares the actual and average duration of visible
emissions for ovens that had a standpipe >20% blocked, with the daily
average for all ovens. The data show that the ovens with standpipe
blockage of >20% had an average charging emission times about the
same as the average charging emission times for all ovens. When com-
pared with all ovens, the ovens with standpipe blockage of >30% have
a longer duration of visible emissions. However, only two ovens were
reported to have 30% blockage--B-22 and A-12 on July 26. These ovens
had emissions for 8.0 and 7.7 seconds, respectively, when the average
for that day was 5.1. Thus, the standpipe blockage data indicate that
a 20% blockage of one standpipe does not have an impact on charging
emissions. There are not enough data to conclude, but it is speculated,
that a >30% blockage of a standpipe impacts charging emissions.
The pusher machine inspector records show that the average time
a chuck door was open prior to the leveling bar entering was about 10
seconds during the entire survey. It was anticipated that lengthy
times might have caused loss of aspiration steam pressure, thus causing
higher than average charging emissions. Since these times were so
short, there was poor correlation between the time duration the chuck
door was open and the charging emissions associated with that oven.
Table 11 contains the analytical results of ten coal samples
gathered daily during the survey and the Company samples collected
during the same four days. These results characterize the coal used
during the survey. Because the Company analyses of the EPA samples
and their own samples are comparable, extra coal sampling is probably
superfluous.
-------
24
The dynamic steam pressures recorded by the catwalk inspectors
ranged between 8.4 kg/cm 2 (120 psi) and 9.8 kg/cm 2 (140 psi). These
pressures were measured in the steam supply line and are not actual
nozzle pressures.
The lowest aspiration steam pressure recorded (8.4 kg/cm 2 - 120
psig) occurred only four times during the survey and showed poor corre-
lation with the duration of visible emissions. In two cases, ovens
with low pressure had significantly less visible emissions than the
average for that day. In another case an oven with low pressure had
significantly more visible emissions, and in the fourth case the oven
had about the average visible emissions.
Studies have shown that a 4.3 m (14 ft) oven required about 62
std. m 3 /min (2,200 scfm) aspriation to adequately control emissions. 4
With the multiport nozzles and a steam pressure of 8.4 kg/cm (120
psig), the lowest steam pressure recorded at CF&I, adequate oven aspira-
tion would be expected. Although this pressure was not measured at
the nozzle, it was measured at topside level downstream from Battery
B ovens being charged.
As mentioned above, VEO observers were instructed to make nota-
tions on their forms when larry car misalignment occurred. They were
also instructed to make notations on their forms of any process upsets,
procedural errors, and other conditions that could affect emissions.
There were five charges during the survey that had emissions in excess
of twice the average for that day [ Table 12]. For four of those five
charges, the observers notations indicated probable causes.
Doors and Topsides
The inspectors findings for damage to knife edges and refractory
and for door cleaning are shown in Figures 2 through 16. These histograms
-------
25
show the number of doors (ordinate) as a function of the number of
sections of a door either damaged, cleaned, or with deposits remain-
ing (abscissa). As an example, from Figure 2 it can be seen that 27
of the 28 push side doors observed had no damage to either the knife
edge or refractory and no data were recorded for the other door (ND).
However, of the 26 cokeside doors observed, 19 had no damage to either
the knife edge or refractory, 6 had damage to one section of the re-
fractory, 5 had damage to one section of the knife edge, 1 had damage
to two sections of the refractory and 2 had damage to two sections of
the knife edge.
The door damage and cleaning histograms are counts only and do
not identify doors. A door-by-door correlation between cleaning,
damage and leaks was not attempted; however, a correlation between
pusher side and cokeside door cleaning damage and leaks was examined.
These data show a poor correlation between door damage/deposits and
door leaks. One reason for the lack of θorrelation may be the subject-
iveness of the procedure for recording door damage and deposits.
Another reason could be that the data base was not large enough to
show such an anticipated correlation.
The team leader recorded that there were 0 to 2 available spare
doors per side per operating unit. However, no process observer noted
that a leaking door was replaced prior to the oven being charged.
Table 13, developed from Company-supplied circular recorder
charts, lists the average hourly collector main pressure at Battery
B. The team leader noted that the pressure only exceeded 12 mm of
water, instantaneously. Collector main pressure was consistently
lower on the cokeside; it fluctuated up to 5 mm of water during a
day. This pressure fluctuation could be partly responsible for the
consistently higher incidence of leaks reported for cokeside doors
and the lack of correlation between door damage! deposits and door
leaks.
-------
26
Pushing
Selected results of the catwalk inspectors observations of offtake
opacity are presented in Table 14; this table only includes those
observations in which one of the 15-second interval opacity observations
was >50%, an arbitrarily selected criterion.
Table 15 lists the maximum pushing emissions opacity from ovens
that had an offtake opacity greater or equal to 50% [ Table 14]. A
comparison of the average pushing emissions from the ovens listed in
Table 15 and the average pushing emissions of all ovens in Tables 6
and 7 shows that only oven A-i had pushing emissions significantly
above average and a significantly higher offtake opacity [ Table 14].
Therefore, these data show a poor correlation between offtake opacity
and pushing emissions. Again, the small data base may be reason for
the poor correlation.
Coking times did not change during the survey, hence their effect
upon emissions could not be evaluated. Coking temperatures were not
correlated because of the difficulty of interpreting the flue temperature
data and the inability to clearly establish what temperature difference
between flues could result in green spots in the coke. The inspectors
were not given objective criteria with which to determine the existence
and extent of a smoking and/or flaming coke face. Hence, no attempt
was made to correlate coke face appearance data with VEO data.

METHOD A
PROCEDURE FOR OBSERVING VISIBLE EMISSIONS EQUAL TO OR GREATER THAN 20%
OPACITY DURING CHARGING
PRINCIPLE
The visible emissions equal to or greater than 20% opacity emitted
from the charging system and oven ports are timed by an observer located on
the topside of the battery. In addition, the maximum opacity observed
during the charge period is recorded.
D E F I NIT IONS
(a) Charging System - any apparatus used to introduce coal into a
coke oven (e.g., a larry car).
(b) Charge Period - the period of time commencing when coal starts
to enter the oven and ending when the last charge port lid is replaced.
(c) Clean-up/Seal Period - the period of time commencing when the
charge period ends and ending when the last charge port lid is either dry-
or wet-sealed whichever is later. This period includes reopening the
lids and sweeping spilled coal into the oven.
(d) Opacity - thedegree to which emissions reduce the transmission
of light and obscure the view of an object in the background.
-------
C-4
PROCEDURE
(a) Position - The observer stands on the topside of the battery
such that a good view of all charge ports of the oven being charged and
the charging system is possible. A position in the center of the battery
at a distance of 10 to 15 ovens from the oven being charged is recommended.
However, the observer may move from side to side, going from pushside to
cokeside and back again; standing in a single spot is not re uired. if
multiple observers are recording the same emissions, the observers should
be positioned as closely to each other as feasible; i.e., a situation where
oven 42 is being charged and one observer is positioned at oven 32 and one
observer is positioned at oven 52, with the larry car between them, is not
acceptable. Observer position is recorded on the data sheet.
(b) Observations - During the charge period the observer watches all
the potential emission sources. For larry car charging the observer watches
the entire charging system, including the larry car hoppers, and the charge
ports. Upon observing any visible emission with an opacity equal to or
greater than 20% opacity, as determined against any contrasting background,
an accumulative stopwatch is started. The watch is stopped when the visible
emission goes below 20% and is restarted when a visible emission equal to
or greater than 20% reappears. The observer continues this procedure for
the entire period. Visible emissions equal to or greater than 20% may
occur simultaneously from several points; e.g., from around all drop
sleeves at the same time. In such a case the visible eii i ssions are timed
collectively, not independently. Also visible emissions equal to or greater
than 20% may start from one source immediately after another source stops.
These are timed as one continuous visible emission equal to or greater
than 20%. The time recorded on the data sheet at the end of the charge
period is the total time on the stopwatch for that period. In addition
to the above, the observer also mentally notes the densest opacity occuring
during the charge period and at the end of the period records on the data
sheet the maximum opacity observed.
-------
C- 5
During some inspections, emissions during the clean up/seal period
may also be required. Using a second accumulative stop iδtch, the inspector
records the total emissions equal to or greater than 20% opacity durirrg
this period, in a manner identical to that used for the charge period.
The following visible emissions are not timed:
(1) Steam vapor;
(2) Visible emissions from burning coal spilled on top of the oven
or oven 1-id;
(3) Visible emissions emitted from any equipment other than the
charging system or oven ports. Standpipe emissions should not be timed
during these periods;
(4) Visible emissions from coke oven doors which may rise above
the battery and which may be windblown across its topside; or
(5) Visible emissions that drift from the top of a larry car hopper,
but have already been timed as a visible emission from the drop sleeve
below the hopper.
Three stations will probably be encountered:
1. Non-mechanical lifters; lidman. By definition, the charge
period ends when the lidman slips the last lid onto the oven port (whether

PROCEDURE FOR OBSERVING ANY VISIBLE EMISSIONS DURING CHARGING
PRINCIPLE
Any visible emissions emitted from the charging system and oven ports
are timed by an observer located on the topside of the battery.
D E F I N IT I ON S
(a) Charging System - any apparatus used to introduce coal into a
coke oven (e.g., a larry car).
(b) Charge Period the period of time commencing when coal starts
to enter the oven and ending when the last charge port lid is replaced.
(c) Clean-up/Seal Period - the period of time commencing when the
charge period ends and ending when the last charge port lid is either dry-
or wet-sealed whichever is later. This period includes reopening the
lids and sweeping spilled coal into the oven.
PROCEDURE
(a) Position - The observer stands on the topside of the battery
such that a good view of all charge ports of the oven being charged and
the charging system is possible. A position in the center of the battery
at a distance of 10 to 15 ovens from the oven being charged is recommended.
Ho. ,ever, the observer may move from side to side, going from pushside to
cokeside and back again; standing in a single spot is not required. If
-------
C- 9
multiple observers are recording the same emissions, the observers should
be positioned as closely to each other as feasible; i.e., a situation where
oven 42 is being charged and one observer is positioned at oven 32 and one
observer is positioned at oven 52, with the larry car between them, is not
acceptable. Observer position is recorded on the data sheet.
(b) Observations - During the charge period the observer watches all
the potential emission sources. For larry car charging the observer -
watches the entire charging system, including the larry car hoppers, and
the charge ports. Upon observing any visible emission, an accumulative
stopwatch is started. The watch is stopped when the visible emission
stops and is restarted when a visible emission reappears. The observer
continues this procedure for the entire period. Visible emissions may
occur simultaneously from several points during a charge; e.g., from
around all drop sleeves at the same time. In such a case the visible
emissions are timed collectively, not independently. Also visible
emissions may start from one source immediately after another source
stops. These are timed as one continuous visible emission. The time
recorded on the data sheet at the end of the charge period is the total
time on the stopwatch for that period.
During some inspections, emissions during the clean-up/seal period
may also be required. Using a second accumulative stopwatch, the inspector
records the total visible emissions during this period, in a manner
identical to that used for the charge period.
The following visible emissions are not timed;
(1) Steam vapor;
(2) Visible emissions from burning coal spilled on top of the oven
or oven lid;
(3) Visible emissions emitted from any equipment other than the
charging system or topside ports. Standpipe emissions should not be
-------
c-b
timed during charging;
(4) Visible emissions emitted from coke oven doors which may rise
above the battery and which may be windblown across its topside; or
(5) Visible emissions that drift from the top of a larry car
hopper, but have already been timed as a visible emission from the drop
sleeve below the hopper.
Three stations will probably be encountered:
1. Non-mechanical lifters; lidman. By definition, the charge
period ends when the lidrnan slips the last lid onto the oven port (whether
or not the lid is properly or totally sealed). The clean-up/seal period
begins at this point and continues until the lids are either dry- or
wet-sealed, whichever is later. It is conceivable, if wet-sealing is
not used, that no clean-up/seal period will exist.
2. Mechanical lifters; wet-sealing. In this case, the charge
period ends when the last lid is replaced mechanically by the larry car.
The seal period begins at this point and ends when the last lid is wet-
sealed.
3. Mechanical lifters; no wet-sealing. In this case, the charge
period ends when the larry car mechanically replaces the last lid. More
than likely, there will be no cleanup/seal period in this situation.
However, if a lidmari is present to reopen the lids and - ieep spilled
coal into the oven, or reseal the lids which are not properly replaced,
the emissions during this period are timed as clean-up emissions.

PROCEDURE FOR OBSERVING VISIBLE EMISSIONS FROM COKE OVEN DOORS
P RI N CI P L E
The coke oven doors that are leaking are recorded by an observer -
making a traverse around the battery. In addition, the opacity at the
lintel of each leaking door is recorded.
DEFI NITIONS
(a) Cokeside Doors - those doors on the side o a battery from which
pushed coke empties into the hot car.
(b) Pushside Doors - those doors on the side of a battery where the
pusher machine is located. Push side doors usually contain the chuck door.
Cc) Chuck Door (or leveler bar door) - a small door on the pushside
which is opened to allow the leveler bar to enter the oven and level coal
during charging.
(d) Jamb Leak - a leak which occurs between the oven brick and the
jamb.
(e) Buckstay Leak - a leak which occurs between the buckstay and
the oven brick.
(f) Lintel - the area from just above the door to the edge of the
top of the battery.
-------
C-l3
(g) Traverse - the movement from one end of the ba-ttery to the other,
inspecting all ovens in the battery.
PROCEDURE
(a) Position - The inspector makes his observations of door emissions
o: t t :t ; az : :Th Yy co Y: s
permit, but generally outside of the pusher machine or quench (hot) car
tracks. The inspector may move to a closer observation point to determine
the source of an emission.
(b) Observation - The inspector starts the observation with an oven
ac either end of the battery and on either the pushside or the cokeside of
the battery. The inspector observes and records any visible emissions from
a door. Visible emissions from the sealing edge around the perimeter of a
door, or, in the case of the pushside, from the door and/or chuck door are
considered as door emissions. Visible emissions from structural leaks,
such a jambs, buckstay or lintel leaks, are not considered as door emissions.
After the inspector has made a visible inspection of the perimeter for door
emissions, a single determination of the opacity of the door emissions is
made at a point above the door, using the battery as a background. This
area is commonly referred to as the lintel. -
The inspector then moves to the adjacentdoor, if ssible, and checks
for door emissions in a like manner. The inspector continues this procedure
down the entire length of the battery. If a temporary machine obstruction
occurs blocking the view of a series of ovens, the inspector may bypass
those ovens and continue down the remainder of the battery, returning to
check the bypassed ovens when that side has been completed.
After the inspector has observed the doors on one side of a battery,
he proceeds directly to the opposite side of the battery. He again starts
-------
C-14
at one end of the battery repeating the same procedures s for the previous
side.
A row of two or more continuous batteries is inspected battery by
battery and not, as e.g., all the pushsides and then all the cokesides.

PROCEDURE FOR OBSERVING VISIBLE EMISSIONS EQUAL TO OR GREATER THAN 20%
OPACITY DURING PUSHING
PR I NC! P L E
The visible emissions equal to or greater than 20% opacity emitted
during the push cycle are timed by an observer located on the cokeside
of the battery. In addition, the maximum opacity observed during the
coke fall period is recorded.
DE F I N 1110 N S
(a) Push Cycle - the period of time commencing when the cokeside
oven door is removed and ending when the coke is quenched. Further, the
push cycle is divided into three periods, as follows:
A B C D
A to B = 1: Period from time door comes_off to ti e start of
ram movement
B to C = 2: Period from time start of ram movement to time all
coke is in hot car
C to D = 3: Period from time all coke is in hot car to time of
quench
(b) Coke Fall Period - the period of time B to C or 2, above.
-------
C-17
(c) Quench - cooling the red hot coke to a temperature below its
ignition temperature at the quench tower.
(d) Quench Tower - the structure, where the quench is carried out,
normally made of wood or brick and designed to conduct the steam plume
generated during the quench into the atmosphere.
(e) Hot Car - the railroad car into which the coke is pushed; sometimes
called the quench car.
(f) Opacity the degree to which emissions reduce the transmission
light and obscure the view of an object in the background.
PROCEDURE
(a) Position - The observer makes the observation from the -cokeside
of the battery, where a clear view of the push can be obtained. In general,
a location on the ground, in the cokeside yard, outside the hot car tracks
approximately perpendicular to the observed oven is acceptable. However,
the observer is not restricted to being on the ground level, but may make
the observation from some elevated level. If multiple observers are re-
cording the same emissions, the observers should be positioned as closely
to each other as feasible. Observer position is recorded on the data sheet.
(b) Observations - During the push cycle the observer watches all
the potential emission sources. These include the oven and the hot car.
Upon observing any visible emission with an opacity equal to or greater
than 20% opacity, as d6termined against any contrasting background, an
accumulative stopwatch is started. The watch is stopped when the visible
emission goes below 20% a,id is -es arz cI wn ±n visiole enission equal co
or greater than 20% reappears. The observer continues this procedure
for the entire push cycle; using either separate stopwatches for each of
-------
C-18
the three periods of the cycle or noting the time for eaη1i period and
recording on the data sheet while employing one or two stopwatches. The
time recorded on the data sheet at the end of each period is the total
time on the stopwatch for that period. In addition to the above, the
observer also mentally notes the densest opacity occurring during the
coke fall period and at the end of the push cycle records on the data
sheet the maximum opacity observed.
The following visible emissions are not timed:
(1) Steam vapor;
(2) Visible emissions generated from jamb cleaning;
(3) Visible emissions from the removed door; or
(4) Visible emissions from the pushside of the oven.
In some cases, coke battery operators will keep the standpipe cap
open during the push cycle. These emissions should be regarded as pushing
emissions.

PROCEDURE FOR OBSERVING VISIBLE EMISSIONS USING A METHOD 9 TYPE
OBSERVATION DURING PUSHING
PRINCIPLE
The opacity of visible emissions emitted during the push cycle is
recorded at fifteen second intervals by an observer located on the
cokeside of the battery.
D E F I N IT IONS
(a) Pushing Cycle - the period of time commencing when thecokeside
oven door is removed and ending when the coke is quenched. Further, the
push cycle is divided into three periods, as follows:
A B 2 c D
A to B = 1: Period from time door comes off to time start of
ram movement
B to C = 2: Period from time start of ram movement to time all
coke is in hot car
C to U = 3: Period from time all coke is in hot car to time of
quench
(b) Coke Fall Period - the period of time B to C or 2, above.
-------
C-21
(c) Quench - cooling the red hot coke to a temperature below its
ignition temperature at the quench tower.
(d) Quench Tower the structure, where the quench is carried out,
normally made of wood or brick and designed to conduct the steam plume
generated during the quench into the atmosphere.
- (e) Hot Car - the railroad car into whicn the coke is pushed; sometimes
called the quench car.
(f) Opacity - the degree to which emissions reduce the transmission
of light and obscure the view of an object in the background.
(g) Method 9 - the visible emissions observation technique published
in 40 CFR Part 60, Appendix A.
PROCEDURE
(a) Position - The observer makes the observation from the cokeside
of the battery, where a clear view of the push can be obtained. In general,
a location on the ground, in the cokeside yard, outside the hot car tracks
approximately perpendicular to the observed oven is acceptable. However,
the observer is not restricted to being on the ground level , but may make
the observation from some elevated level. If multiple observers are re-
cording the same emissions, the observers should be positftned as closely
to each other as feasible. Observer position is recorded on the data sheet.
(b) Observations During the push cycle the observer watches all
the potential emission sources at 15 second instances. These include
the oven arid the hot car. The observer determines the opacity of the
pushing emissions at every 15 second instance at the densest point of the
emissions, as read against any contrasting background. Reading commences
-------
C-22
when the door is removed. In addition to recording the opacity, the
inspector records at the period of the push cycle and the specific back-
ground used for the opacity determination. The observer continues this
procedure until the coke is quenched.
The following visible emissions are not timed:
(1) Steam vapor;
(2) Visible emissions generated from jamb cleaning;
(3) Visible emissions from the removed door; or
(4) Visible emissions from the pushside of the oven.
In some cases, coke battery operators will keep the standpipe cap
open during the push cycle. These emissions should be recorded as pushing
emissions. -

PROCEDURE FOR OBSERVING VISIBLE EMISSIONS FROM TOPSIDE LEAKS
USING A MULTIPASS TRAVERSE
PRINCIPLE
- The visible emissions emitted from offtake systems and charge port
lids ar d t2r- r 4 ned visually by an observer making a sepa - t trav se
for the offtake system and for the charge port lids.
DEFINITIO 1S
(a) Offtake System - the apparatus for each oven that provides a
passage for gases from an oven to the collection main.
(b) Collection Main - the apparatus connected to one or more offtake
systems that provides a passage for conveying gases from the offtake
system to the byproduct plant cross-over collection main.
(c) Charge Port - Any opening in the topside of an oven, provided
by a masonry casting.
(d) Chart Port Lid - any apparatus used to cover an open charge
port.
(e) Stationary Jumper Pipe - any apparatus permanently connecting
two ovens br the purpose of increasing oven aspiration during charging.
(f) Decarbonization Period - a period of time for combusting oven
carbon that commences when oven lids are removed from charge ports no
-------
C-26
no earlier than 30 minutes before the oven is pushed and ends with the
initiation of the next charge of that oven.
(g) Luting - a process by which charge port lids are wet-sealed to
retard escape of emissions to the atmosphere.
(h) Traverse - the movement from one end of the battery to the
other, inspecting all oven in the battery.
(i) Significant Leak - any offtake s stem leak which is greater
than one rrleter i -ienqth.
(j) Total Leak - any offtake system or charge port lid leak.
PROCEDURE -
(a) Position - The observer makes the observation from the topside
of the battery, traversing the battery near the centerline. During the
traverse, the observer may stray from the centerline of battery if the
observer believes an investigation is required to determine whether or
not a leak exists. If the observer does deviate from the battery center-
line during a traverse to look at a particular source, this is noted on
the data sheet.
In performing a traverse, the inspector observes offtake system
leaks in one direction and charge port lid leaks in the return traverse.
The offtake system leak traverse is conducted in the direction where the
sun is most behind the inspectors back.
(b) Observations - The observer traverses the coke battery at a
steady pace, pausing only to make appropriate entries on the data sheet.
The inspector may use a stopiatch to record the time required for the
-------
C-27
traverse. If the observer is de1ayed4 y _the larry car, the watch is
stopped and restarted. The time required for the traverse is recorded
on the data sheet.
The inspector should stand back far enough from the offtake system(s)
or charge port lids in order to p -ovide a clear view of them. If for some
reason the centerline cannot be used to provide such a clear view, the
observer should select a viewing location on the topside further from
(rather than closer to) the units being inspected; this situation may
occur if the standpipes are extremely tall (greater than 15 feet). In
ca,a , Fox mpia, the obsarvec may trave:se aiong the cckesice
edge in order to observe a pushside offtake system. If a double offtake
system battery has extremely tall o Fftakes, it is conceivable that two
traverses may be required for each run, i.e., one traverse along the
cokeside edge of topside to observe the pushside offtake system and one
traverse along the pushside edge of topside to obser-ve the cokeside
offtake system. In such a case, the two traverses may be required, whereas
a single traverse is preferred.
During any one traverse, the observer may record on the data sheet
total leaks from charge port lids, or may record total and significant
leaks from offtake systems (and stationary jumper pipes).
The numbers for all ovens with lids and offtakes open for decarbon-
ization are noted on the data sheet with the appropriate comment. In
addition, if a leak from one of the open sources exists, the number of
significant and/or total leaks are recorded in the appropriate columns
of the data sheet; however, the oven number is circled to indicate the
oven was decarbor.izing.
The following visible emissions are not recorded:
(1) Steam vapor;
-------
C-28
(2) Coal smoldering on the topside; or
(3) Visible emissions from flue caps.
