(a) For the purpose of this section the term “by- product coke plant” means a plant used in connection with the distillation process to produce coke in which the volatile matter in coal is expelled, collected, and recovered. Such plant consists of, but is not limited to, coal and coke handling equipment, by-product chemical plant and other equipment associated with and attendant to the coking chambers or ovens making up a single battery operated and controlled as a unit.
(B) Visible Air Contaminants from Operation of Coke Oven Battery.
(1) Charging Emissions.
A. No person shall discharge into the atmosphere during the charging cycle of a coke oven battery from the charging holes, larry car or standpipes any visible air contaminants except for a cumulative total not to exceed two hundred (200) seconds over a period of five (5) consecutive charges between March 31, 1978 and December 31, 1978 and one hundred fifty (150) seconds over a period of five (5) consecutive charges on or after January 1, 1979.
B. The emissions from the charging cycle shall include all emissions from the time that the gate(s) on a larry car coal hopper is (are) opened or mechanical feeds start the flow of coal into the ovens until the last charging hole lid is replaced.
(2) Charging Hole Port Emissions.
A. No person shall discharge into the atmosphere visible air contaminants at any time from more than five percent (5%) of the charging hole ports on any one (1) battery during any fifteen (15) consecutive minutes.
B. For the purpose of this subsection the denominator shall be the total number of charging hole ports on the battery and the numerator shall be the number of charging ports for operating ovens from which there was a visible emission during an inspection excluding oven(s) being charged and the two (2) ovens being decarbonized which follow the last oven being charged in accordance with the operating schedule. The inspection shall be made by a single observation performed as rapidly as conditions permit and inclusive of all ports.
(3) Standpipe (Offtake Pipes) Emissions.
A. No person shall discharge into the atmosphere visible air contaminants at any time for more than twelve percent (12%) of the offtake piping (standpipes) of any coke oven battery during any fifteen (15) consecutive minutes.
B. For the purpose of this subsection the denominator shall be the total number of offtake pipes on the battery and the numerator shall be the number of offtake pipes for operating ovens from which there was a visible emission during an inspection excluding oven(s) being charged and the two (2) ovens being decarbonized which follow the last oven being charged in accordance with the operating schedule. The inspection shall be made by a single observation performed as rapidly as conditions permit and inclusive of all offtake pipes.
(4) Coke Oven Doors.
A. No person shall discharge into the atmosphere from any opening on or seal of a coke oven door visible air contaminants, except for nonsmoking flame, from more than sixteen percent (16%) of the coke oven doors on any one (1) battery during any twenty (20) consecutive minutes.
B. No person shall fail to adjust, repair or replace a coke oven door, found to be leaking for thirty (30) minutes or more after an oven is charged, prior to the next coking cycle which starts during the daylight turn.
C. No person or operator of a coke oven battery shall fail to maintain coke oven doors and a coke oven door repair facility capable of prompt and efficient repair of coke oven doors and seals. No person shall fail maintain an inventory of one (1) coke door for twelve (12) coke ovens operated.
D. For the purpose of this subsection an oven door and the associated chuck door on the pusher side of the battery shall be considered as one (1) door. The denominator shall be the number of coke oven doors for operating ovens on any battery and the numerator shall be the number of coke oven doors or seals which have one (1) or more visible emissions during an inspection excluding oven(s) being charged.
(5) Pushing Emissions.
A. No person shall discharge into the atmosphere during the pushing cycle of a coke oven battery visible air contaminants greater than fifteen percent (15%) opacity except for accumulative total not to exceed one hundred eighty (180) seconds over a period of three (3) consecutive pushes.
B. For the purpose of this section the pushing cycle shall begin when the coke oven door is removed and shall end when the quench car enters the quench tower.
(6) Combustion Stack Emissions. No person shall discharge into the atmosphere from the combustion stack of a coke oven battery visible air contaminants in excess of the limitations as set forth in Section 265.01.
(c) Unloading, Handling, Transfer and Storage of Coal and Coke. No person shall cause, suffer, allow or permit coal or coke to be unloaded, handled, transferred or stored without taking all necessary and reasonable precautions to prevent particulate matter from becoming airborne. Such precautions shall be taken as set forth in Section 277.07.
(d) Coke Quenching Tower.
(1) No person shall cause or allow the operation of a coke quenching tower unless such tower is equipped with effective interior baffles.
(2) No person shall cause or allow the wet quenching of coke unless the quality of make-up water used for such quenching is equivalent to the quality of water established for the nearest stream or river by regulation of the Ohio Environmental Protection Agency, except that water from the nearest stream or river or treated process water may be used for the quenching of coke. For the purpose of this section, treated process water means waste water treated physically and/or chemically for the removal of suspended solids, phenols, cyanides, ammonia, oil, grease and/or other substances to the degree approved by the Commissioner.
