On November 15, 1993, federal regulations for visual emissions testing of coke producing facilities went into effect. Method 303, the determination of visible emissions from a by-product coke oven battery, is the toughest standard these plants have ever had to meet. Becoming certified is also extremely tough.
Method 303 regulations require that each battery be "read" everyday
of the year. Allowable emissions are based on the percentage of leaks
found per area and the average time of leaking emissions per charge
over a thirty day rolling average. The areas that are examined for
Method 303 are coke oven doors, charging ports or topside lids,
offtakes, collection mains, and the timing of emissions during charging.
By calculating emissions on a rolling average, a clearer picture of the
overall battery's condition, both from an operating and maintenance
standpoint, can be seen.
