Small Business Assistance - Permit Primer

New or Expanding Business - Exemptions

Whether you were not exempt under one of the specific categories or you have units that don't fit in a specific category definition, you may still be exempt based on your total emissions from the project (check the emission levels below). You may wish to attempt the calculations on your own (see below) or you may prefer to contact DNR or Department of Commerce air staff to help you determine if you are exempt (see contact information - left margin).

To qualify for a general exemption you must meet ALL of these levels.

Whether you attempt the calculations yourself or you would rather contact DNR or Department of Commerce Air Staff, please have the following information ready:

1)Material Safety Data Sheets (MSDS)

(associated with coatings, solvents, cleaners, raw materials, etc.)

2)Heat Input Rating (in BTUs)

(e.g. boilers, furnaces, heating units. The rating is usually found on furnace specification sheet or on furnace itself)

3)Maximum raw material usage (all processes)

(e.g. paint guns, woodworking equipment, printing presses, etc.)

 

Now that you have determined your status, please choose the "Exempt" or "Not Exempt" button below to continue.
