Policy and Interpretive Statements for Environmental Public Health

A policy statement describes an agency’s current approach to implementing laws, court decisions, or orders, including its practices or procedures, while an interpretive statement explains the agency’s opinion on the meaning of those laws or decisions. These statements are advisory only (not enforceable), used for focused guidance, and filed with the Office of the Code Reviser.

Policy and interpretive statements remain in effect or active until updated or rescinded. Statements are reviewed regularly. Agencies are encouraged to convert long-standing policy and interpretive statements into rule.

Below are the active policy and interpretive statements in the division of Environmental Public Health, organized by office. All statements are in PDF format.
