I got a reply from them:

My request to them via the online contact us form:

Hello,
I'd like to be on the notifications list for this closure and the environmental analysis.

10-01-2010-02, Former Allenspark Dump shooting closure, dated 4/27/10

Is this contact information sufficient or is there another way to sign up for the notifications?

Thanks, -----.

Hope this helps - a few of us should be on the contact list for this "analysis" they are doing, so we can monitor and make suggestions if necessary to their findings.
