The oil and gas inspector shall have the authority to require the immediate shutting in or closing of any well if he finds that there exists, within a one hundred foot (100') radius of any well, any gas or gasoline vapor in a quantity sufficient to constitute, in his judgment, or in the judgment of the city fire marshal, a fire hazard. The well shall remain shut in or closed until the hazard and its cause are removed. (Ord. 528 §1, 1982)
