Ill. Admin. Code tit. 35, § 726.219
b) When an owner and operator requests an extension of time to enable the facility to comply with the alternative hydrocarbon provisions of Section 726.204(f) and obtain a RCRA permit because the facility cannot meet the HC limit of Section 726.204(c):
1) The Board will do the following, in considering whether to grant the extension:
2) If an extension is granted, the Board will, as a condition of the extension, require the facility to operate under flue gas concentration limits on CO and HC that, based on available information, including information in the Part B permit application, are baseline CO and HC levels as defined by Section 726.204(f)(1).
BOARD NOTE: Derived from 40 CFR 266.103(c)(7)(ii) (2017).
The owner or operator may request a case-by-case extension of time to extend any time limit provided by Section 726.203(c). The operator must file a petition for a RCRA variance pursuant to 35 Ill. Adm. Code 104. The Board will grant the variance if compliance with the time limit is not practicable for reasons beyond the control of the owner or operator.
