On June 19, 2020, U.S. EPA’s Central Data Exchange (CDX) will be decommissioning one of its Exchange Network Node endpoints in order to increase operational efficiency and reduce maintenance costs. The retiring endpoint is associated with a seldom used service called the Node Relay located at https://noderelay.epa.gov/Node2/Node2WS.svc. The Node Relay endpoint was only used by a very limited number of partners for two active data flows, including Facility Identification 3.0  and the Emissions Inventory System (EIS).

Most partner agencies will not be impacted by this change. If you are still pointing your data flows to submit to the Node Relay endpoint, please update your settings to use https://node2.epa.gov/Node2WS.svc. Please make this change by June 19, 2020. After that date, the Node Relay endpoint will be decommissioned and data flows using that endpoint will fail. As a reminder, you can find a complete list of CDX Node endpoints for each data flow on the Exchange Network website.
