New York Codes, Rules and Regulations › Title 6 - DEPARTMENT OF ENVIRONMENTAL CONSERVATION › Chapter III - AIR RESOURCES › Subchapter A - PREVENTION AND CONTROL OF AIR CONTAMINATION AND AIR POLLUTION › Part 214 - By-product Coke Oven Batteries › Section 214.8 - Charging hole lids and offtake piping

Current through Register Vol. 46, No. 28, July 10, 2024
(a) Charging hole lids. No more than two
				  percent of all oven lids may emit visible emissions, as measured in accordance
				  with the procedure set forth in subdivision (c) of this section.
(b) Offtake piping. No more than 10 percent
				  of the offtake piping on a single battery may emit visible emissions, as
				  measured in accordance with the procedure set forth in subdivision (c) of this
				  section.
(c) For the purpose of
				  determining compliance with subdivisions (a) and (b) of this section, visible
				  emissions are those emissions of any degree of opacity greater than zero
				  observed to be leaking from any point on the battery topside except from oven
				  flue caps and between refractory bricks.
(1)
				  Compliance with the standard for charging hole lids will be determined while
				  walking topside along the length of the battery, observing each oven lid for
				  only that time necessary to determine whether or not there is a visible
				  emission coming from the charging hole casting and lid interface, but will not
				  include smoke from burning of smoldering excess topside coal. The observer will
				  then shift attention to the adjacent oven lids and check for emissions in the
				  same manner. The observer will continue this procedure along the entire length
				  of the battery. For the purpose of inspection, an ignited dampered oven
				  requires that a flame is observed above any one charging hole. The dampered
				  oven will be included in the calculations for determining the percentage of
				  leaking lids if there is no flame visible above the plane of the opening on any
				  single charging hole. The percentage of leaking lids will be calculated by
				  dividing the number of leaking lids by the total number of lids on the
				  in-service ovens on the battery and multiplying by 100. Oven lids on a maximum
				  of six dampered ovens are exempt from this procedure provided they are
				  ignited.
(2) Compliance with the
				  standard for offtake piping will be determined while walking topside as close
				  as possible to the centerline of the battery and observing the offtake piping
				  of each oven for only that time necessary to determine whether or not there is
				  a visible emission coming from the offtake piping on that oven. In the event
				  such positioning results in an obstructed view, the observer may assume other
				  positioning to allow a clear view of the emissions. The observer will then
				  shift attention to the adjacent offtake piping and check for emissions in the
				  same manner. The observer will continue this procedure along the entire length
				  of the battery. For the purpose of inspection, an ignited dampered oven
				  requires that a flame is observed above any offtake piping cap opening. The
				  dampered oven will be included in the calculations for determining the
				  percentage of leaking offtake piping if there is no flame visible above the
				  plane of the opening on the offtake pipe. The percentage of leaking offtake
				  piping will be calculated by dividing the number of leaking offtake piping by
				  the total number of offtake piping on the in-service ovens on the battery and
				  multiplying by 100. Offtake piping on an oven being charged and on a maximum of
				  six dampered ovens, including an oven being pushed is exempt from this
				  procedure provided that emissions from the dampered ovens are ignited once the
				  oven is dampered.
