Ill. Admin. Code tit. 35 § 280.107
Compliance with the offtake piping emission limitation contained in Rule 203(d)(5)(B)(vi) of the Illinois Pollution Control Board Rules and Regulations, Chapter 2: Air Pollutions shall be determined by the following procedure:
Observations of any visible emissions from the offtake piping shall be made by traversing the topside of the battery near the centerline one time. During the traverse, the observer may stray from the centerline and walk as close as possible to the offtake piping in order to determine whether an observed emission is coming from the offtake piping. Each oven shall be observed in sequence.
The observer shall record the battery identification, the points of offtake piping emission from any oven, and the oven number.
Compliance with Rule 203(d)(5)(B)(vi) shall be determined by utilizing the following formula:
(# of offtake pipes on operating | |||
ovens with visible emissions) | x 100 | = | 10% or less |
(#of offtake pipes on operating | |||
ovens) | |||
