r (1) Wastes may remain exposed after completion of closure; or (2) Short term, incidental access by the public or domestic livestock may pose a hazard to human health. (c) Post -closure use of the property on or in which hazardous waste remains after closure shall never be allowed to disturb the integrity of the final cover, liner(s), or any other components of any containment system, or the function of the facility's monitoring systems, unless the owner or operator can demonstrate to the California Regional Water Quality Control Board either in the post - closure plan or by petition, that the disturbance: (1) Is necessary to the proposed use of the property, and will not increase the potential hazard to human health or the environment; or (2) Is necessary to reduce a threat to human health or the environment. (d) The owner or operator shall provide post -closure care in accordance with the approved post -closure plan for at least 30 years after the date of completing closure. However, the owner or operator may petition the California Regional Water Quality Control Board to allow some or all of the requirements for post -closure care to be discontinued or altered before the end of the 30 -year period. The petition shall include evidence demonstrating the secure nature of the facility that makes continuing the specified post -closure requirement(s) unnecessary (e.g., no detected leaks and none likely to occur, characteristics of the waste, application of advanced technology, or alternative disposal, treatment, or re -use techniques ). Alternately, the California Regional Water Quality Control Board may require the owner or operator to continue one or more of the post -closure care and maintenance requirements contained in the facility's post -closure plan for a specified period of time. The California Regional Water Quality Control Board may do this if they find there has been noncompliance with any applicable standards or requirements, or that such continuation is necessary to protect human health or the environment. At the end of the specified period of time, the California Regional Water Quality Control Board will determine whether to continue or terminate post -closure care and maintenance at the facility. The owner or operator may petition the California Regional Water Quality Control Board for an extension or reduction of the post -closure care period based on cause. These petitions will be considered by the California Regional Water Quality Control Board at the time the post -closure plan is submitted and at five-year intervals after the completion of closure.
