Any solid waste collector proposing to expand his solid waste collection business for the purpose of providing new solid waste collection services, and the proposed expansion of services is not set forth in a tariff previously filed with and accepted by the board, shall file with the board appropriate revised tariff sheets which reflect the proposed changes in services to be provided.c.
