13. In Part 63, Appendix A is amended by revising,Methods 303, 303A, 304A, 304B, 305, 306, 306A, and 306B to,read as follows:,1957,METHOD 303-DETERMINATION OF VISIBLE EMISSIONS FROM,BY-PRODUCT COKE OVEN BATTERIES,NOTE: This method is not inclusive with respect to,observer certification. Some material is incorporated by,reference from other methods in appendix A to 40 CFR part,60. Therefore, to obtain reliable results, persons using,this method should have a thorough knowledge of Method 9.,1.0 Scope and Application.,1.1 Applicability. This method is applicable for the,determination of visible emissions (VE) from the following,by-product coke oven battery sources: charging systems,during charging; doors, topside port lids, and offtake,systems on operating coke ovens; and collecting mains. This,method is also applicable for qualifying observers for,visually determining the presence of VE.,2.0 Summary of Method.,2.1 A certified observer visually determines the VE,from coke oven battery sources. Certification procedures,are presented. This method does not require that opacity of,emissions be determined or that magnitude be differentiated.,3.0 Definitions.,1958,3.1 Bench means the platform structure in front of,the oven doors.,3.2 By-product Coke Oven Battery means a source,consisting of a group of ovens connected by common walls,where coal undergoes destructive distillation under positive,pressure to produce coke and coke oven gas, from which byproducts,are recovered.,3.3 Charge or charging period means the period of,time that commences when coal begins to flow into an oven,through a topside port and ends when the last charging port,is recapped.,3.4 Charging system means an apparatus used to charge,coal to a coke oven (e.g., a larry car for wet coal charging,systems).,3.5 Coke oven door means each end enclosure on the,push side and the coking side of an oven. The chuck, or,leveler-bar, door is considered part of the push side door.,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 between two adjacent buck stays.,3.6 Coke side means the side of a battery from which,the coke is discharged from ovens at the end of the coking,cycle.,1959,3.7 Collecting main means any apparatus that is,connected to one or more offtake systems and that provides a,passage for conveying gases under positive pressure from the,by-product coke oven battery to the by-product recovery,system.,3.8 Consecutive charges means charges observed,successively, excluding any charge during which the,observer's view of the charging system or topside ports is,obscured.,3.9 Damper-off means to close off the gas passage,between the coke oven and the collecting main, with no flow,of raw coke oven gas from the collecting main into the oven,or into the oven's offtake system(s).,3.10 Decarbonization period means the period of time,for combusting oven carbon that commences when the oven lids,are removed from an empty oven or when standpipe caps of an,oven are opened. The period ends with the initiation of the,next charging period for that oven.,3.11 Larry car means an apparatus used to charge coal,to a coke oven with a wet coal charging system.,3.12 Log average means logarithmic average as,calculated in Section 12.4.,3.13 Offtake system means any individual oven,apparatus that is stationary and provides a passage for,1960,gases from an oven to a coke oven battery collecting main or,to another oven. Offtake system components include the,standpipe and standpipe caps, goosenecks, stationary jumper,pipes, mini-standpipes, and standpipe and gooseneck,connections.,3.14 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.,3.15 Oven means a chamber in the coke oven battery in,which coal undergoes destructive distillation to produce,coke.,3.16 Push side means the side of the battery from,which the coke is pushed from ovens at the end of the coking,cycle.,3.17 Run means the observation of visible emissions,from topside port lids, offtake systems, coke oven doors, or,the charging of a single oven in accordance with this,method.,3.18 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.,1961,3.19 Standpipe cap means An apparatus used to cover,the opening in the gooseneck of an offtake system.,3.20 Topside port lid means a cover, removed during,charging ……
