Current through Register Vol. 46, No. 28, July 10, 2024
(a) Door
				  leakage. No more than 10 percent of all coke oven doors on a single battery
				  including pusher side, coke side and chuck doors may emit visible emissions as
				  measured in accordance with the procedure set forth in subdivision (b) of this
				  section.
(b) For the purpose of
				  determining compliance with subdivision (a) of this section, visible emissions
				  are those emissions of any degree of opacity greater than zero, observed to be
				  emanating from the oven doors of a battery. An inspection of the coke oven
				  doors will consist of an observer or observers walking the length of a coke
				  battery at a steady pace from a ground level position (25 to 100 feet from the
				  battery). Each door (coke side, push side and chuck doors) is to be observed
				  during the inspection for only that period of time necessary to determine
				  whether or not there is a visible emission coming from the door. The observer
				  will then shift his attention to the adjacent door, if possible, and check for
				  emissions in the same manner. If a temporary machine obstruction occurs,
				  blocking the view of one or more ovens, those oven(s) will be bypassed and the
				  remaining doors on that side of the battery will be inspected. After the
				  traverse on that side of the battery, the bypassed ovens and only those ovens
				  will be reinspected. Compliance will not be determined if it is not possible to
				  reinspect the blocked ovens. Where the inspector has reason to believe that
				  emissions emanate from a leaking chuck door within a leaking oven door, the
				  emissions will be counted as two leaks. The percentage of leaking doors will be
				  calculated by the following equation:
Percentage of Leaking Doors =(A/B x C)
A =100 x (number of leaking doors)
B =number of doors/oven
C =number of inservice ovens/battery
The number of doors/oven is normally three--pusher side,
					 coke side and chuck. Compliance is determined for all doors in aggregate, not
					 for each separate door type.
(c) Oven door maintenance. Any person
				  operating a by-product coke oven battery must implement the following work
				  practices:
(1) Self-sealing coke oven doors.
(i) Each oven door will be inspected for
				  visible emissions within one hour after the charge. A record will be made of
				  any door leaking one hour after the charge.
(ii) Doors leaking one hour after the charge
				  will be adjusted prior to the end of the second hour after the
				  charge.
(iii) Each oven door
				  leaking one hour after the charge will be reinspected for visible emissions two
				  hours after the charge. A record will be made of any door leaking two hours
				  after the charge.
(iv) Any door
				  leaking two hours after each of two successive charges must be replaced with a
				  repaired or rebuilt door prior to the next charge to that oven.
(v) An adequate supply of repaired and
				  rebuilt doors will be maintained on site to allow the frequency of replacement
				  necessary to comply with this section.
(vi) If a newly installed, rebuilt or
				  repaired door leaks more than two hours after the charge, the door and jamb
				  must be inspected when the door is next removed from the oven. If the door is
				  found to be defective, it must be replaced with a repaired or rebuilt door to
				  that oven as soon as it is reasonably possible, normally within two charges to
				  that oven. If the door is not found to be defective, the jamb must be replaced
				  as soon as it is reasonably possible.
