Visible Emissions from By-Product Coke Oven Batteries – USEPA Method 303

USEPA Method 303 is used 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;
• collecting mains.

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.
 
This method is also applicable for qualifying observers for visually determining the presence of VE.
