The State Corporation Commission is hereby vested with jurisdiction over the sales of natural gas pursuant to this section, and may adopt such rules and regulations as may be necessary with respect thereto, but nothing in this act shall create in any manner an obligation or duty on the part of the operator of any well or gathering pipeline, who furnishes gas under the provisions of this act, to assume in any way public utility duties to the public at large, except as such duties may arise from such operator's acts separate and apart from any performance of obligations imposed under this act.
