Frequent Questions

How may I participate in the forum?

The discussion forum is open to the public for commenting. Comments are moderated according to our comment policy.  The views expressed in comments do not necessarily reflect the official views of the U.S. Environmental Protection Agency or the Federal government.

After the forum closes for comments, EPA will place the entire discussion forum, with comments included and attached to their associated post, in the docket for this public dialogue, EPA-HQ-OPPT-2011-0516, which will be available at

In what order do the posts appear?

Posts are added in reverse chronological order, with the newest post at the top of the home page. To find any older posts that do not appear on the main page, you can use the “previous post” function at the bottom of the page.

Why do you ask for my name, organization, and e-mail address when I leave a comment? How do you protect my privacy?

Providing your name, organization, or e-mail address is optional. We ask for your name and organization to make it easier to carry on a conversation with other commenters  and to help provide context for your comment, so we will publish your name and organization along with your comment.

We ask for your e-mail address so that we may contact you if necessary.  We will not publish your e-mail address.  To protect yourself, please do not include information that identifies your contact information in the body of your comment, such as e-mail addresses or phone numbers.

We do not edit comments, so we will not be able to publish comments containing such information.

Beyond the issues above, we treat privacy issues associated with this discussion forum under our privacy policy provided on EPA’s main website.

How can I find out more?
