Traditional Permits

For power plants and other significant air emission sources, air permits have traditionally been written and issued individually, one at a time. This process can take a long time. (To distinguish these permits from other new types of permits, DNR calls them "traditional? permits.)

In some cases, traditional permits are required by federal law, such as for major facilities like paper mills, utilities, or the larger printing shops. In other cases, the reviews may be desirable because they can better help an industry understand which air regulations apply to them and what they need to do to comply with those regulations.
