What is a State Environmental Assessment Worksheet (EAW) and why is one being completed? The Minnesota Environmental Policy Act and the related Minnesota Environmental Quality Board (EQB) guidelines require project proposers complete environmental reviews for various types of projects. According to Minnesota Statutes Chapter 473, Section 614, an Environmental Assessment Worksheet (EAW) is required for MAC reliever airport projects that involve construction of a runway or taxiway extension and the expenditure of more than $2,000,000. An EAW provides an analysis of the potential environmental impacts of a specific project. The standard EAW form issued by the EQB will be completed and included as an appendix to the Federal EA.
