Minnesota Administrative Rules

4717.7810 HEALTH RISK LIMITS; PURPOSE AND SCOPE.

Subpart 1.

Purpose.

The purpose of parts 4717.7810 to 4717.7900 is to establish health risk limits (HRLs) for substances found to degrade Minnesota groundwater.

Subp. 2.

Scope.

A.

As provided by Minnesota Statutes, sections 103H.005, subdivision 3, and 103H.201, subdivision 1, HRLs are derived as human health-based groundwater standards based on cancer or noncancer effects from consumption and federal maximum contaminant levels incorporated by reference as required by Laws 2007, chapter 147, article 17, section 2.

B.

Health risk limits are for use by public agencies and private entities in Minnesota in determining whether groundwater, impacted by human activity, is subject to regulatory or advisory actions based on human health concerns. HRLs specify a minimum level of quality for water used for human consumption, such as ingestion of water, and do not imply that allowing degradation of water supplies to HRL levels is acceptable.
