Nevada Revised Statutes Title 40. Public Health and Safety § 445B.580. Officer of Department may inspect or search premises;  search warrant

1. It is a condition of the issuance of any operating permit required by the Commission or pursuant to any local ordinance for the control of air pollution that the holder of the operating permit agrees to permit inspection of the premises to which the permit relates by any authorized officer of the Department at any time during the holder's hours of operation without prior notice. This condition must be stated on each application form and operating permit.

2. If a source of air contaminant exists or is constructed or operated without an operating permit, such an officer may inspect it at any reasonable time, and may enter any premises to search for such a source. If entry is refused, or before attempting to enter, such an officer may apply to any magistrate for a search warrant. The magistrate shall issue the warrant if the magistrate believes from the supporting affidavit or affidavits that there is probable cause to believe that a source of air contaminant exists or is being constructed or operated on the premises to be searched.
