An Automated Public Correspondence System

eComment (short for electric-comment system) is a comment response application that you may use to submit questions and comments to EPA. The system assigns your question to an EPA employee or contractor so that they can provide a response. It includes a method for you to check the status of submitted comments and update the details of previously submitted comment(s).

To view the status of an e-comment or add clarifying text, you must provide your email address with the initial submission. When the comment is submitted, it will be assigned a unique number. Using this number and your email you can look up your comment and any response provided by EPA. If you did not provide an email address with your comment, it is considered for informational purposes only, and no response will be issued.
