Solid waste management must be regulated to the extent necessary to protect the health, safety and welfare of the public. This system is intended to encourage private garbage collection services within the unincorporated areas of this county, and to encourage compliance with all federal and state laws and regulations governing the collection, transportation and disposal of solid and hazardous wastes, and otherwise to protect the environment of the county. The county shall have only one designated landfill, otherwise known as the Blue Bench landfill, within the county. It is further necessary to protect the health, safety and welfare of the public to require that all solid waste (other than sludge and certain hazardous and pathological wastes which, by law, cannot be disposed of within the county) generated within the county, and is collected by an approved collection agent, must be transported and delivered to the designated county landfill. Private collection stations may be licensed and authorized by the county. (1998 Code § 8.20.020)
