NR 407.05(4)(a) (a) Identifying information, including company name and address, and plant name and address if different from the company name or address, owner’s name and agent, and operator if different from the owner, and names and telephone numbers of the plant manager and contact person.

NR 407.05(4)(b) (b) A description of the source’s processes and products, by standard industrial classification code as described in the Standard Industrial Classification Manual, 1987, incorporated by reference in s. NR 484.05, including any processes and products associated with each alternate operating scenario identified by the source.

NR 407.05(4)(c) (c) The following emissions-related information:

NR 407.05(4)(c)1. 1. The maximum theoretical emissions of all air contaminants from all emissions units, operations, and activities except for those exempted under subd. 9. or 10. Fugitive emissions from emissions units, operations, and activities shall be included in the permit application in the same manner as stack emissions, regardless of whether the source category in question is included in the list of sources contained in the definition of major source. Maximum theoretical fugitive emissions shall be calculated using average operating conditions and average weather conditions. Only sources that manufacture or treat pesticides, rodenticides, insecticides, herbicides, fungicides, or pharmaceuticals shall include emissions of air contaminants identified as falling within the categories in Table 3 in permit applications. When preparing an application, the owner or operator of a facility may rely on information in an approved material safety data sheet. Trace contaminants need not be reported if they constitute less than 1% (10,000 parts per million) of the material, or 0.1% (1,000 parts per million) of the material if the air contaminant is listed with a control requirement in column (i) of Table A, B or C of s.
