In addition to all other powers and duties now conferred by law upon county commissions, such commissions are hereby empowered to establish, operate and maintain, either directly or by contract, garbage and refuse collection and disposal services, and to pay for the establishment, operation and maintenance of such collection and disposal services, in whole or in part, either out of general funds in the county treasury, or out of special funds to be derived from fees charged to and paid by the users of such services or a combination of both such general revenue or special fund: Provided, That the power and authority hereby conferred upon county commissions shall not be exercised in territory included within the boundaries of any municipal corporation, except as provided herein. Any county commission for the purpose of implementing this section is hereby authorized to enter into such contract or contracts with any municipality or county within this state for the purposes of carrying out the powers vested in such county commissions by this section, and all said county commissions may, pursuant to such contract, exercise the authority herein granted within such contracting municipality: Provided, however, That where an area is furnished garbage and refuse collection service by an existing carrier under authority issued by the Public Service Commission of West Virginia, the county commission may enter into contracts or agreements with such carrier to supplement such existing service, but shall not enter into any competing service without authority being granted by the Public Service Commission.

The term "users" as used herein shall mean and include any person to whom such services are made available under the provisions of this section.

The authority granted by this section expires on January 1, 1989.
