The Statement of Need and Reasonableness, or SONAR, is required for every rulemaking of this type. The Minnesota Department of Natural Resources has prepared this SONAR to satisfy the requirements of Minn. Stat. §14.131 (2015) and Minn. Rule §1400.2070 (2015). The SONAR provides justification as to why the rules are needed and reasonable, and includes a rule-by-rule analysis that describes the rationale for each rule provision.
