Section 280.101  Preamble and Statutory Authority

a)         On September 6, 1979, the Pollution Control Board adopted a Final Order in its regulatory proceeding R78-10 which amended its previously adopted particulate emission limitations for steel manufactoring processes.  Included in the R78-10 regulations are limitations of visible emissions from the following by-product coke plant emission sources and/or operations:

            Rule 203(d)(5)(B)(ii) – charging operations

            Rule 203(d)(5)(B)(iv) – coke oven doors

            Rule 203(d)(5)(B)(v) – coke oven lids

            Rule 203(d)(5)(B)(vi) – coke oven offtake piping

b)         The regulations specify maximum time periods during which visible emissions are permitted during charging operations and maximum percentages of doors, lids, and offtake piping that are permitted to emit visible emissions. The purpose of this Rule is to establish procedures by which observers are able to determine the compliance status of by-product coke oven batteries subject to Rules 203(d)(5)(B)(ii), 203(d)(5)(B)(iv), 203(d)(5)(B)(v), and 203(d)(5)(B)(vi).

c)         This Rule is promulgated pursuant to authority conferred on the Environmental Protection Agency by Sections 4(b), 4(e), 4(g), 4(m), 30 and 39(a) of the Environmental Protection Act, Ill. Rev. Stat., ch. 111 ½, pars. 1004(b), (e), (g) and (m), 1030 and 1039(a), and by Rule 203(d) (5) (B) the Illinois Pollution Control Board Rules and Regulations, Chapter 2:  Air Pollution.
