The agencies are hosting this webcast to help explain the key elements of the proposal. In order to provide access to as many people as possible, this system is a webcast rather than a webinar. This means there will not be an opportunity for questions and answers, and participants must join via an internet-connected device (there will be no dial-in audio). There is a limit of 2,000 attendees for the live webcast, however the webcast will be recorded and hosted on the agencies’ websites for later review. The agencies encourage participants to submit comments through the official docket for this rulemaking at http://www.regulations.gov under Docket ID No. EPA–HQ–OW–2018–0149.
