1995,METHOD 303A-DETERMINATION OF VISIBLE EMISSIONS FROM,NONRECOVERY COKE OVEN BATTERIES,NOTE: This method does not include all of the,specifications pertaining to observer certification. Some,material is incorporated by reference from other methods in,this part and 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 and Method 303.,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.,1996,3.4 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,1997,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,1998,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.,1999,The intent of this ……
