285.17(1)(a) (a) The department, by rule, shall classify air contaminant sources which may cause or contribute to air pollution, according to levels and types of emissions and other characteristics which relate to air pollution, and may require reporting for any such class. Classifications made pursuant to this section may be for application to the state as a whole or to any designated area of the state, and shall be made with special reference to effects on health, economic and social factors, and physical effects on property.
285.17(1)(b) (b) Any person operating or responsible for the operation of air contaminant sources of any class for which the rules of the department require reporting shall make reports containing such information as the department requires concerning location, size and heights of contaminant outlets, processes employed, fuels used and the nature and time periods of duration of emissions, and such other information as is relevant to air pollution and available or reasonably capable of being assembled.
285.17(2) (2)
285.17(2)(a)(a) The department may, by rule or in an operation permit, require the owner or operator of an air contaminant source to monitor the emissions of the air contaminant source or to monitor the ambient air in the vicinity of the air contaminant source and to report the results of the monitoring to the department. The department may specify methods for conducting the monitoring and for analyzing the results of the monitoring. The department shall require the owner or operator of a major source to report the results of any required monitoring of emissions from the major source to the department no less often than every 6 months.
285.17(2)(b) (b) Before issuing an operation permit that contains a monitoring requirement relating to the emissions from an air contaminant source, the department shall notify the applicant of the proposed monitoring requirement and give the applicant the opportunity to demonstrate to the administrator of the division of the department that administers this chapter that the proposed monitoring requirement is unreasonable considering, among other factors, monitoring requirements imposed on similar air contaminant sources. If the administrator determines that the monitoring requirement is unreasonable, the department may not impose the monitoring requirement. If the administrator determines that the monitoring requirement is reasonable, the applicant may obtain a review of that determination by the secretary. The secretary may not delegate this function to another person. If the secretary determines that the monitoring requirement is unreasonable, the department may not impose the monitoring requirement.
285.17(3) (3)The department may not post on the Internet any information that is required to be reported to the department under this chapter and that relates to a facility's air emissions, including the nature and duration of specific emissions of an air contaminant source and any results of monitoring the emissions of a contaminant source or the ambient air in the vicinity of a contaminant source, unless the department certifies that the information is accurate on the date on which the information is posted.
285.17(4) (4)The department shall evaluate the reporting, monitoring, and record-keeping requirements it imposes, as of July 2, 2013, on owners and operators of stationary sources that are required to have operation permits under s. 285.60 but that are not required to have operation permits under the federal clean air act. The department shall promulgate rules that simplify, reduce, and make more efficient those requirements, consistent with any applicable requirements under the federal clean air act.

Any duly authorized officer, employee or representative of the department may enter and inspect any property, premises or place on or at which an air contaminant source is located or is being constructed or installed at any reasonable time for the purpose of ascertaining the state of compliance with this chapter and s. 299.15 and rules promulgated or permits issued under this chapter or s. 299.15. No person may refuse entry or access to any authorized representative of the department who requests entry for purposes of inspection, and who presents appropriate credentials. No person may obstruct, hamper or interfere with any such inspection. The department, if requested, shall furnish to the owner or operator of the premises a report setting forth all facts found which relate to compliance status.
