1.a. The director shall be permitted to enter any property other than residences, at any time, and residences at such reasonable times for the purpose of inspection, observation, set up and use of monitoring equipment, sampling, testing, or inspecting and copying records in accordance with the provisions of this chapter; provided, that:

            (1) If such property is occupied he shall first present proper credentials to the occupant and request entry, explaining his reasons therefor; and

            (2) If such property is unoccupied, he shall first make a reasonable effort to locate the owner of such property and request entry, explaining his reason therefor.

            b. If such entry is refused or cannot be obtained because the owner of such property cannot be found after due diligence, the director shall have recourse to every remedy provided by law to secure lawful entry for the above stated purposes.

    2. Notwithstanding the foregoing, if the director has reasonable cause to believe that waters or wastes of the types referred to in Sections 13.07.090 and 13.07.100 are being discharged from any property into a public sewer or natural outlet, and has reasonable cause to believe that such discharge is so dangerous, hazardous or unsafe as to require immediate inspection to safeguard the public health or safety, he shall have the right to immediately enter and inspect such property, and may use any reasonable means required to effect such entry and make such inspection, whether such property is occupied or unoccupied and whether or not permission to inspect has been obtained.  If the property is occupied, he shall first present the proper credentials to the occupant and demand entry, explaining his reasons therefor and the purpose of his inspection. No person shall fail or refuse, after proper demand has been made upon him, as provided in this subsection, to promptly permit the director to make any inspection provided for by this subsection.  Any person violating this subsection is guilty of a misdemeanor.

    3. The director shall have no authority to inquire into any processes including metallurgical, chemical, oil, refining, ceramic, paper or other industries beyond that point having a direct bearing on the kind and source of discharge to the sewers or waterways or facilities for waste treatment.

    4. While performing the necessary work on property referred to in this section, the director shall observe all applicable safety rules established by the owner of the property. (Ord. 83/T-2039; S-39108, 1979).
