Subpart 1.


The purpose of parts 4717.8000 to 4717.8600 is to establish health risk values (HRVs) and multimedia health risk values (MHRVs) for chemicals or defined mixtures of chemicals emitted to the ambient air.

Subp. 2.


The HRVs and MHRVs established in parts 4717.8000 to 4717.8600 are intended for use by public agencies or private entities in Minnesota as one set of criteria in evaluating risks to human health by chemical emissions to the ambient air. The chemicals and defined mixtures of chemicals included in parts 4717.8000 to 4717.8600 do not include every toxic chemical emitted to air.

The HRVs and MHRVs were not developed for evaluation of workplace exposures. The Occupational Safety and Health Administration, United States Department of Labor, is responsible for regulating workplace exposures.
