(a) A public employer may submit in writing data relating to the abatement of a hazard to be considered by an authorized representative of the Director. The authorized representative shall notify the interested parties if such data will be used to modify an abatement order.
     (b) Within 15 business days after receiving a citation, proposed assessment of a civil penalty, or notice of failure to correct a violation, a public employer or the employer’s agent may request that an authorized representative of the Director review abatement dates, reclassify violations (such as willful to serious, serious to other than serious), or modify or withdraw a penalty, a citation, or a citation item, or any combination of those, if the employer presents evidence during the informal conference which convinces the authorized representative that the changes are justified.
