1.0 Scope and Application.
1.1 Applicability.
This method is applicable for the determination of visible emissions (VE) from
leaking doors at nonrecovery coke oven batteries.
2.0 Summary of Method.
2.1 A certified
observer visually determines the VE from coke oven battery sources while
walking at a normal pace. This method does not require that opacity of
emissions be determined or that magnitude be differentiated.
3.0 Definitions.
3.1 Bench
Means the platform
structure in front of the oven doors.
3.2 Coke oven door
Means each end
enclosure on the push side and the coking side of an oven.
3.3 Coke side
Means the side of a
battery from which the coke is discharged from ovens at the end of the coking
cycle.
3.4 Nonrecovery coke oven battery
Means a source
consisting of a group of ovens connected by common walls and operated as a
unit, where coal undergoes destructive distillation under negative pressure to
produce coke, and which is designed for the combustion of coke oven gas from
which by-products are not recovered.
3.5 Operating oven
Means any oven not
out of operation for rebuild or maintenance work extensive enough to require
the oven to be skipped in the charging sequence.
3.6 Oven
Means a chamber in
the coke oven battery in which coal undergoes destructive distillation to
produce coke.
3.7 Push side
Means the side of the
battery from which the coke is pushed from ovens at the end of the coking
cycle.
3.8 Run
Means the observation
of visible emissions from coke oven doors in accordance with this method.
3.9 Shed
Means an enclosure
that covers the side of the coke oven battery, captures emissions from pushing
operations and from leaking coke oven doors on the coke side or push side of
the coke oven battery, and routes the emissions to a control device or system.
3.10 Traverse time
Means accumulated
time for a traverse as measured by a stopwatch. Traverse time includes time to stop and write down oven
numbers but excludes time waiting for obstructions of view to clear or for time
to walk around obstacles.
3.11 Visible Emissions or VE
Means any emission
seen by the unaided (except for corrective lenses) eye, excluding steam or
condensing water.
4.0 Interferences. [Reserved]
5.0 Safety.
5.1 Disclaimer.
This method may
involve hazardous materials, operations, and equipment. This test method may
not address all of the safety problems associated with its use. It is the
responsibility of the user of this test method to establish appropriate safety
and health practices and determine the applicability of regulatory limitations
prior to performing this test method.
5.2 Safety Training.
Because coke oven
batteries have hazardous environments, the training materials and the field
training (Section 10.0) shall cover the precautions required by the company to
address health and safety hazards. Special emphasis shall be given to the
Occupational Safety and Health Administration (OSHA) regulations pertaining to
exposure of coke oven workers (see Reference 3 in Section 16.0). In general,
the regulation requires that special fire-retardant clothing and respirators be worn in certain
restricted areas of the coke oven battery. The OSHA regulation also prohibits
certain activities, such as chewing gum, smoking, and eating in these areas.
6.0 Equipment and Supplies. [Reserved]
7.0 Reagents and Standards. [Reserved]
8.0 Sample Collection, Preservation, Transport, and Storage. [Reserved]
9.0 Quality Control. [Reserved]
10.0 Calibration and Standardization.
10.1 Training.
This method requires
only the determination of whether VE occur and does not require the
determination of opacity levels; therefore, observer certification according to
Method 9 in Appendix A to Part 60 is not required. However, the first-time
observer (trainee) shall have attended the lecture portion of the Method 9
certification course. Furthermore, before conducting any VE observations, an
observer shall become familiar with nonrecovery coke oven battery operations
and with this test method by observing for a minimum of 4 hours the operation
of a nonrecovery coke oven battery in the presence of personnel experienced in
performing Method 303 assessments.
11.0 Procedure.
The intent of this
procedure is to determine VE from coke oven door areas by carefully observing
the door area while walking at a normal pace.
11.1 Number of Runs.
Refer to ¤
63.309(c)(1) of this part for the appropriate number of runs.
11.2 Battery Traverse.
To conduct a battery
traverse, walk the length of the battery on the outside of the pusher machine
and quench car tracks at a steady, normal walking pace, pausing to make
appropriate entries on the door area inspection sheet (Figure 303A-1). The
walking pace shall be such that the duration of the traverse does not exceed an
average of 4 seconds per oven door, excluding time spent moving around
stationary obstructions or waiting for other obstructions to move from
positions blocking the view of a series of doors. Extra time is allowed for
each leak (a maximum of 10 additional seconds for each leaking door) for the
observer to make the proper notation. A walking pace of 3 seconds per oven door
has been found to be typical. Record the actual traverse time with a stopwatch.
A single test run consists of two timed traverses, one for the coke side and
one for the push side.
11.2.1 Various
situations may arise that will prevent the observer from viewing a door or a
series of doors. The observer has two options for dealing with obstructions to
view: (a) wait for the equipment to move or the fugitive emissions to dissipate
before completing the traverse; or (b) skip the affected ovens and move to an
unobstructed position to continue the traverse. Continue the traverse. After
the completion of the traverse, if the equipment has
moved or the fugitive
emissions have dissipated, complete the traverse by inspecting the affected
doors. Record the oven numbers and make an appropriate notation under
"Comments" on the door area inspection sheet (Figure 303A-1).
NOTE: Extra time incurred for handling obstructions is
not counted in the traverse time.
11.2.2 When batteries
have sheds to control pushing emissions, conduct the inspection from outside
the shed, if the shed allows such observations, or from the bench. Be aware of
special safety considerations pertinent to walking on the bench and follow the
instructions of company personnel on the required equipment and operations
procedures. If possible, conduct the bench traverse whenever the bench is clear
of the door machine and hot coke guide.
11.3 Observations.
Record all the
information requested at the top of the door area inspection sheet (Figure
303A-1), including the number of non-operating ovens. Record which side is
being inspected, i.e., coke
side or push side. Other information may be recorded at the discretion of the
observer, such as the location of the leak (e.g., top of the door), the reason for any
interruption of the traverse, or the position of the sun relative to the
battery and sky conditions (e.g.,
overcast, partly sunny, etc.).
11.3.1 Begin the test
run by traversing either the coke side or the push side of the battery. After
completing one side, traverse the other side.
11.3.2 During the
traverse, look around the entire perimeter of each oven door. The door is
considered leaking if VE are detected in the coke oven door area. The coke oven
door area includes the entire area on the vertical face of a coke oven between
the bench and the top of the battery and the adjacent doors on both sides.
Record the oven number and make the appropriate notation on the door area
inspection sheet (Figure 303A-1).
11.3.3 Do not record
the following sources as door area VE:
11.3.3.1 VE from
ovens with doors removed. Record the oven number and make an appropriate
notation under "Comments";
11.3.3.2 VE from
ovens where maintenance work is being conducted. Record the oven number and
make an appropriate notation under "Comments"; or
11.3.3.3 VE from hot
coke that has been spilled on the bench as a result of pushing.
