TRI Hotlines

What hotlines are available to answer questions via telephone regarding different aspects of TRI reporting?

There are three main hotlines that can assist callers via phone with questions about different aspects of the TRI reporting requirements:

  1. The Superfund, TRI, EPCRA, RMP & Oil Information Center can assist callers in understanding the TRI regulations, guidance, and reporting requirements, as well as properly completing forms with TRI-MEweb.
  2. The Central Data Exchange (CDX) Helpdesk can assist TRI-MEweb Preparers and Certifiers with CDX technical issues, such as registration for or access to CDX accounts, CDX user IDs, and passwords; the status of reports submitted via TRI-MEweb; access to CDX data flows; step-by-step instructions for TRI-MEweb submission and receipt; and TRI-MEweb technical problems (e.g., Data Quality Alerts (DQAs), Notices of Significant Errors (NOSEs), and critical errors).
  3. The TRI Data Processing Center (DPC) can answer questions about the processing and status of Electronic Signature Agreements (ESAs); and verify EPA’s receipt of facility reports. Please note that all calls received by the TRI DPC will automatically go to a voice-mail system. Phone calls will be returned within 24 hours.  If you need immediate assistance, please call the CDX Hotline.
