The department shall require that the owner or operator of every major hazardous waste facility provide evidence of financial responsibility for the duration of the operation of the facility and establish a mechanism to defray closing costs and post-closure monitoring expenses for such period of time as may be deemed necessary by the department, whether by escrow accounts, performance bonds or otherwise. Post-closure monitoring of major hazardous waste facilities shall be assumed by the department 30 years subsequent to the closure of a particular facility.
