Any person, firm, corporation, or association who digs, drills, excavates, constructs, or owns, or controls a well from which natural gas flows shall, upon the abandonment of the well, cap or otherwise close the mouth of or entrance to the well in such a manner as to prevent the unnecessary or wasteful escape of natural gas into the atmosphere.

No person, firm, corporation, or association who owns or controls land in which such a well is situated shall wilfully permit natural gas flowing from the well wastefully or unnecessarily to escape into the atmosphere.
