Reporting RFS RIN transactions in the EPA Moderated Transaction System

EMTS v4.3 released on April 4, 2016

On April 4, 2016, EPA released a new version of the EPA Moderated Transaction System (EMTS) that contains several back-end enhancements.

For a full list of functionality enhancements, click the following link:

Parties who transact Renewable Identification Numbers (RINs) under the Renewable Fuel Standard must enter transaction information in the EPA Moderated Transaction System (EMTS) within five (5) business days.



Regulated parties are urged to conduct due diligence investigations and exercise caution when conducting RIN transactions. Neither EPA nor its systems, including the EMTS, certify or validate RINs or make any provision for parties who, despite good faith, transfer or receive invalid RINs. As specified in the regulations at 40 CFR 80.1431 (b)(2), invalid RINs cannot be used to achieve compliance with the Renewable Volume Obligations of an obligated party or exporter, regardless of the party's good faith belief that the RINs were valid at the time they were acquired. Additionally, the regulations at 40 CFR 80.1460(b)(2) prohibit the creation or transfer to any person of a RIN that is invalid.

Follow these steps to report RIN transactions using EMTS:

Step 1: Review the following reference documents

Step 2: Submit transactions

There are two ways to submit transactions in EMTS:

  • Web Interface
    Most users login to the web interface and use the data entry screens to report transactions or submit XML files that contain multiple transactions.
  • Node  
    Some companies set up nodes to transmit and receive XML files directly to and from the EMTS system without using the web interface.

Reference the following documents for submitting XML files through the web interface or a node:
