Following an informal conference, unless the employer and Department have entered into a settlement agreement, the Director shall send the employer an amended citation or notice of no change. The employer has 15 working days from the receipt of the amended citation or notice of no change to notify the Director that the employer wishes to contest the citation or proposed assessment of penalty, whether or not amended. If, within 15 working days from the receipt of the notice issued by the Director, the employer fails to notify the Director in writing that the employer requires an informal conference to be held or intends to contest the citation or proposed assessment of penalty, and no notice is filed by any employee or representative of employees under the provisions of this Article within such time, the citation and the assessment as proposed to the Commissioner shall be deemed final and not subject to review by any court.
