In the case of a Type "AA" or Type "A" violation, a penalty may be assessed from the date on which the violation is discovered. In the case of a Type "B" or Type "C" violation or an administrative warning issued pursuant to Sections 3-401 through 3-413 or the rules promulgated thereunder, the facility shall submit a plan of correction as provided in Section 3-303. In the case of a Type "B" violation or an administrative warning issued pursuant to Sections 3-401 through 3-413 or the rules promulgated thereunder, a penalty shall be assessed on the date of notice of the violation, but the Director may reduce the amount or waive such payment for any of the following reasons:
If a plan of correction is approved and carried out for a Type "C" violation, the fine provided under Section 3-305 shall be suspended for the time period specified in the approved plan of correction. If a plan of correction is approved and carried out for a Type "B" violation or an administrative warning issued pursuant to Sections 3-401 through 3-413 or the rules promulgated thereunder, with respect to a violation that continues after the date of notice of violation, the fine provided under Section 3-305 shall be suspended for the time period specified in the approved plan of correction.
If a good faith plan of correction is not received within the time provided by Section 3-303, a penalty may be assessed from the date of the notice of the Type "B" or "C" violation or an administrative warning issued pursuant to Sections 3-401 through 3-413 or the rules promulgated thereunder served under Section 3-301 until the date of the receipt of a good faith plan of correction, or until the date the violation is corrected, whichever is earlier. If a violation is not corrected within the time specified by an approved plan of correction or any lawful extension thereof, a penalty may be assessed from the date of notice of the violation, until the date the violation is corrected.
