Any county or municipality may, by ordinance, provide that no sanitary landfill facility located within the unincorporated area, if a county, or the incorporated area, if a municipality, may accept for final disposal at any time truckloads composed primarily of leaves generated within the county in which the facility is located, except that leaves separated at the source from other municipal waste may be accepted by a sanitary landfill facility in those instances where the facility has provided and maintains for that purpose separate composting facilities, and the composted leaves are utilized either as part of the final vegetative cover for the landfill, or for other uses as a soil conditioning material.
