EPA is experiencing intermittent outages with its Central Data System (CDX) services due to recent firewall upgrades (ipV6). These outages affect all CDX customers, including e-GGRT users. In some cases, the outages may interfere with an e-GGRT user's ability to perform certain functions in e-GGRT, including logging in and/or certifying reports. EPA is working to resolve the problem. Thank you for your patience.
