Did you know that you can review draft versions of government agency documents including those administered by the CDC at www.regulations.gov.  The site allows anyone to review and comment on these proposed documents for a period of time.  Beyond greenhouse gas emission and endangered species classifications, you may be interested in CDC proposed guidelines like the draft guidelines for the prevention of surgical site infections.  These are available via search of the site or more easily here.  You can download a pdf of the draft and then comment by the deadline which in this case is Feb 28th.
