A.R.S. § 49-765

Each county, city or town may establish regulations for private collection of solid waste within its area of jurisdiction, including standards for equipment, hours of operation, license fees and insurance requirements as necessary and appropriate to operate a solid waste collection program. Ordinances or regulations authorized by this section and section 49-704 shall be equal to or more stringent than this chapter and rules and regulations adopted by the department under this chapter. If authorized by statute, each county, city or town may provide for civil penalties for violation of such ordinances or regulations provided that such penalties do not exceed the penalties authorized by this chapter. A county, city or town may not provide for or enforce a criminal penalty against a person who refuses to purchase solid waste collection services from a private service provider unless the private service provider contracts with the county, city or town to provide solid waste collection services and the solid waste collection service is billed through the county, city or town.
