4. Assess civil penalties for each day the assisted living facility is or was out of compliance with the terms of its license and the health, safety, and welfare of residents are at risk, which shall be paid into the state treasury and credited to the Assisted Living Facility Education, Training, and Technical Assistance Fund created pursuant to § 63.2-1803.1; however, no civil penalty shall be imposed pursuant to this subdivision on any assisted living facility operated by an agency of the Commonwealth. The aggregate amount of such civil penalties shall not exceed $10,000 for assisted living facilities in any 12-month period. Criteria for imposition of civil penalties and amounts, expressed in ranges, shall be developed by the Board, and shall be based upon the severity, pervasiveness, duration, and degree of risk to the health, safety, or welfare of residents. Such civil penalties shall be applied by the Commissioner in a consistent manner. Such criteria shall also provide that (i) the Commissioner may accept a plan of correction, including a schedule of compliance, from an assisted living facility prior to setting a civil penalty, and (ii) the Commissioner may reduce or abate the penalty amount if the facility complies with the plan of correction within its terms. A single act, omission, or incident shall not give rise to imposition of multiple civil penalties even though such act, omission, or incident may violate more than one statute or regulation. A civil penalty that is not appealed becomes due on the first day after the appeal period expires. The license of an assisted living facility that has failed to pay a civil penalty due under this section shall not be renewed until the civil penalty has been paid in full, with interest, provided that the Commissioner may renew a license when an unpaid civil penalty is the subject of a pending appeal;
