Public comments are one of many ways Idahoans can support informed decision-making. To provide effective comments, follow these tips:
- Reference the facility name, permit number, project, or document on which you are commenting.
- Ensure your comments address the technical and regulatory analyses of the proposed permit or project.
- Address environmental impacts of a proposed permit or project (e.g., air quality impacts associated with a draft permit).
- Use examples and provide supporting materials when appropriate.
- Offer suggestions to address a concern or solve a problem such as timing, design, etc.
