Health Risk Values Rules for Air - EH: Minnesota Department of Health

Health Risk Values Rules for Ambient Air

The Minnesota Department of Health (MDH) promulgated Health Risk Values (HRVs) for chemicals in ambient air in March 2002. These values were established through a scientific and stakeholder involvement process. For additional information, see the links below, Air Guidance Values or contact us at health.risk@state.mn.us.

The Statement of Need and Reasonableness (SONAR) (PDF) for the HRV Rules provides a thorough description of the scientific methods and principles used to develop HRVs.

Note: SONARs are written for a specific step in the rule development process. The HRV SONAR does not reflect all information that was included in the HRV Rules. See the Responses to Comments on the Proposed Permanent Rule (PDF) for additional considerations and information incorporated into the HRV Rules.
