Small Business Assistance - Permit Primer

Existing Business - Exemptions

Even if you were not exempt in some of the specific categories, you may be exempt based on your total emissions (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.)

Click on each of the categories that fits emissions sources at your facility to help you with performing calculations to determine if you are exempt under the general exemptions.
