Air episode advisory. The department may issue an Air Pollution Episode advisory to the general public if any air contaminant or combination of air contaminants reaches the respective level of concentration specified in Table 1 at any monitoring site.
NR 493.03(2)
(2) Air episode levels. The department shall declare an Air Pollution Episode Level at the “Alert", “Warning" or “Emergency" stage if any air contaminant or combination of air contaminants reaches the respective level of concentration specified in Table 1 at any monitoring site and if meteorological conditions are such that the concentrations of the air contaminant can be expected to remain at or above that level for 12 or more hours, or in the case of ozone, to recur the following day at the same or a higher level, unless control actions are taken.

NR 493.04 Emission control action programs. NR 493.04(1)(1) Any person responsible for the operation of a direct source which emits 0.25 tons or more per day of any air contaminant for which air standards have been adopted shall prepare emission control action programs, consistent with good industrial practice and safe operating procedures, for reducing the emission of the air contaminants into the outdoor atmosphere during periods of an AIR POLLUTION ALERT, AIR POLLUTION WARNING, or AIR POLLUTION EMERGENCY declared under
s. NR 493.03 (2). Emission control action programs shall be designed to reduce or eliminate emissions of air contaminants into the outdoor atmosphere in accordance with the requirements set forth in Tables 2 to 6.
NR 493.04(2)
(2) Emission control action programs as required under
sub. (1) shall be in writing and show the source of air contamination, the approximate amount of reduction of contaminants, the approximate time required to put the program into effect, a brief description of the manner in which the reduction will be achieved during each stage of an air pollution episode declared under
s. NR 493.03 (2), and such other information as the department deems pertinent.
NR 493.04(3)
(3) The emission control action programs as required by
sub. (1) shall be made available at all times on the premises of the operation to any person authorized to enforce the provisions of the department's episode procedure. A brief written description of the overall emission control action program, and the details of the program which affect specific functions of the overall operation, shall be posted at the locations where the functions are carried out.
NR 493.04(4)
(4) The emission control action programs as required by
sub. (1) shall be submitted to the department upon request within 60 days of the receipt of the request; the emission control action programs shall be subject to review and approval by the department. If, in the opinion of the department, an emission control action program does not effectively carry out the requirements set forth in Tables 2 to 6, the department may disapprove the emission control action program, state its reason for disapproval, and order the preparation of an amended emission control action program within the time period specified in the order. If the person responsible fails within the time period specified in the order to submit an amended emission control action program which, in the opinion of the department, meets the requirements of this chapter, the department may revise the emission control action program. The revised program will thereafter be the emission control action program which the person responsible shall put into effect upon declaration of an air pollution episode by the secretary.
