IMPORTANT REMINDER:

Regulated parties are urged to conduct due diligence investigations and 

exercise caution when conducting Renewable Identification Number (RIN) 

transactions. Neither EPA nor its systems, including the EPA Moderated 

Transaction System (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.

Accessing EMTS 

To support the Renewable Fuel Standard (RFS2) program, the EPA Moderated Transaction System (EMTS) 

has been developed to screen the generation and transfer of RINs between renewable fuel producers, 

importers, exporters, obligated parties, and non-obligated RIN owners. 

You can access the EMTS website only through the Central Data Exchange (CDX). To do so, open your 

Internet browser, either Internet Explorer 7.0 and higher or Firefox 2.0 and higher (no other browsers are 

currently supported), and enter the following URL: https://cdx.epa.gov/SSL/CDX/login.asp. Log in using

your MyCDX user name and password. From your account profile, click the "OTAQ EMTS Application" link

under Available Account Profiles (see Figure 1). If you do not see the "OTAQ EMTS Application" link, refer 

to "Getting Started - MyCDX" for further instructions.

Figure 1: OTAQ EMTS Application Link

Clicking the link will take you to the EMTS Home page (see Figure 2).

Selecting an Organization

Upon accessing the EMTS Home page, you will need to select an organization to represent if you are 

affiliated with two or more organizations. To do so, click one of the organizations in the Select an 

Organization popup (see Figure 3). You must select an organization to represent before you can perform 

any actions on the EMTS website. 

Figure 3: Select an Organization Popup

To confirm that you are now representing the selected organization, verify that the statement in the upper 

right corner of the page -- "Logged in as:" -- contains your CDX user ID followed by the name of the 

appropriate organization. Note that you may change the organization you are representing by clicking on 

the Organizations tab of the accordion on the right side of select pages (see Figure 4). 
EMTS User's Guide

December 2011

Page 3 

Figure 4: Organizations Accordion Tab

The Organizations tab will appear in this accordion on the following pages:

● Home page; 

● View Blocked List;

● View Node Submissions; 

● View Web Submissions; 

● Review Trades; 

● Manage Subscriptions;

● View Reports;

● Compliance Data;

● Manage RIN Holdings; and

● Transaction Bin. 

After you open the Organizations tab of the accordion, click "Select a Different Organization." In the Select 

an Organization popup, click the name of the organization you wish to represent. Upon doing so, the 

organization name in the upper right corner of the page should reflect the new organization you selected. 

Once you have selected an organization, you are ready to begin using the EMTS website functionality. 

Viewing Registered Data

To view the data for which your organization is registered in the OTAQ Registration system, hover over the 

Organizations menu options, and select View Organizations. On the View Organizations page, a grid 

displays a list of the organizations you have been associated with in OTAQReg: Fuels Programs Registration 

application. For each organization, you may use the "I want to..." drop-down menu to select an 

organization or to view the registered data for that organization. If you choose the Select Organization 

option, the organization name in the upper right corner of the page should change to reflect the 

organization that you identified, and the activities and reports on the EMTS website will be limited to that 

organization. The View Registered Data page displays your organization’s registered business activities, 

users and their roles, and facilities. From this page, you can view the details for the organization’s 
EMTS User's Guide

registered facilities. Choosing the View Registered Data option will take you to the View Registered Data 

page for the selected organization (see Figure 5). 

Figure 5: View Registered Data

 

The View Facility Data page displays the registered fuels, fuel categories, processes, feedstocks, and coproducts for the selected facility (see Figure 6). 
EMTS User's Guide

December 2011

Page 5 

Figure 6: View Facility Data

You may only edit your registered data through OTAQReg: Fuels Programs Registration. The registered 

data in EMTS is updated nightly from OTAQReg: Fuels Programs Registration. If you make changes to your 

registration in OTAQReg, the changes will be reflected in EMTS the morning after they have been activated 

by EPA.

Viewing RIN Holdings

To view your RIN holdings, hover over RINs on the main menu of the EMTS website and select View RIN 

Holdings (Current). The Manage RIN Holdings page is organization-specific (indicated by the organization 

name above the RIN Holdings grid, circled in Figure 7 below). To switch the organization for which you are 

viewing RIN holdings, open the Organizations tab of the accordion, and click "Select a Different 

Organization." 
EMTS User's Guide

December 2011

Page 6 

Figure 7: Manage RIN Holdings Page

If you view the Manage RIN Holdings page before your organization has completed any generate or buy 

transactions, the RIN Holdings grid will be empty (see Figure 7). At this point, you can generate or buy 

RINs (the only valid transaction types when there are no RIN Holdings) either by clicking the Generate or 

Buy button or by selecting Generate or Buy in the "I want to..." drop-down and clicking Go.

Once you have completed a generate transaction or successfully purchased RINs from a trading partner, the 

RIN Holdings grid will now display your RINs (see Figure 8 for an example). Each row in the RIN Holdings 

grid represents a unique combination of Fuel (D Code), RIN Year, and Assignment. For each row, the sum 

of RINs in the Available, Pending, Reserved, and Locked columns should equal the number of RINs in the 

Total column. The RINs in the Available column are RINs that are available for you to use in transactions. 

The RINs in the Pending column are RINs that are involved in a pending sell transaction that you have 

initiated (see the Trading RINs section). The RINs in the Reserved column are RINs that are associated 

with transactions in the Transaction Bin (see the Managing the Transaction Bin section). Finally, the RINs 

in the Locked column are RINs that have been locked either by your organization or by the EPA. 
EMTS User's Guide

December 2011

Page 7 

Figure 8: Populated RIN Holdings Grid Example

The final column in the RIN Holdings grid is the "I want to..." column. The drop-down for each row contains 

the options View Details, Generate, Buy, Separate, Separate (Upward delegation), Sell, Retire (Obligation), 

and Retire (Other). The options that are not applicable to the corresponding row of RINs will be grayed 

out. For example, Retire (Obligation) is only applicable for separated RINs being retired by Non-renewable 

Fuel Importers, Renewable Fuel Exporters, and Refiners, so in all other instances, the option will be grayed 

out. If you select a transaction in the "I want to..." column for a row of RINs, the Fuel (D Code), RIN Year, 

and Assignment fields in the resulting transaction wizard will be pre-populated with the data from that 

row. 

Viewing RIN Batch Details and Locking RINs

To view all of the RIN batches that make up a row in the RIN Holdings grid, select View Details in the "I 

want to..." column and click Go. Doing so takes you to the View RIN Holding Details page (see Figure 9).
EMTS User's Guide

December 2011

Page 8 

Figure 9: View RIN Holding Details Page

The View RIN Holding Details page includes a Search box that allows you to search for RIN batches that 

satisfy a specific set of criteria. The RIN Holding Details grid displays the originating source information 

(originating organization, facility, and batch number) for each batch of RINs with the Fuel (D Code), RIN 

Year, and Assignment that you selected on the RIN Holdings page. It also includes the status of each RIN 

batch. For pending and reserved RINs, the options in the "I want to..." drop-down are View Details and 

Transaction. Selecting View Details takes you to a RIN Batch Details page. Selecting Transaction takes you
EMTS User's Guide

December 2011

Page 9 

to a page with the details of the last transaction that acted on that RIN batch. For available RINs, the "I 

want to..." drop-down options are View Details, Transaction, and Lock RINs. Selecting Lock RINs takes you 

to the Lock RINs Confirmation page (see Figure 10). 

Figure 10: Lock RINs Confirmation Page

The page contains the details of the RINs that you are about to lock along with a required Comment field. 

After you enter a comment and press Confirm, you will return to the View RIN Holding Details page. For 

the RIN batch that you locked, the Status field will display Locked, and the Locked By field will include the 

name and organization of the individual that locked the RIN batch. Locked RINs will not be available for 

any transactions. 

The EPA has the capability to lock any organization's available or locked RIN batches. If the EPA locks one 

of your organization's RIN batches, the Status field for that row will display Locked, and the Locked By field 

will display EPA. RINs locked by the EPA cannot be used in transactions and cannot be unlocked by your 

organization. 
EMTS User's Guide

December 2011

Page 10

If you wish to unlock a batch of RINs locked by your organization and not locked by the EPA, select Unlock 

RINs in the "I want to..." drop-down. Like the Lock RINs Confirmation page, the Unlock RINs Confirmation 

page requires a comment. Once you confirm the unlock action, the RINs will have a status of Available, and 

you will be able to use them to complete transactions. Note that if the EPA locks a batch of RINs that your 

organization had already locked, the EPA will need to unlock the RINs before you will have the ability to 

unlock the RIN batch. 

Viewing Expired RIN Holdings

To view your Expired RIN Holdings, hover over RINs on the main menu of the EMTS and click View Expired 

RIN Holdings (see Figure 11):

Figure 11: Select View Expired RIN Holdings

The Expired RIN Holdings page is organization-specific (indicated by the organization name at the top of 

the page). To switch the organization for which you are viewing expired RIN holdings, open the 

Organizations tab of the accordion on the right side of the page, and click "Select a Different Organization." 

If you view the RIN Holdings page before your organization has retired any RINs, the RIN Holdings grid will 

contain the message “Nothing found to display.” To filter on Fuel, RIN Year, or Assignment Code, select the

filter options and click Filter (see Figure 12). 
EMTS User's Guide

December 2011

Page 11

Figure 12: View Expired RIN Holdings

Note: A RIN is valid for compliance during the year that it was generated and the following calendar 

year. The time period for retiring a RIN for a particular year extends two months into the 

following year. The maximum amount of time a RIN can be valid in EMTS is two years and two

months.

Generating RINs 

From the Manage RIN Holdings page, you have the option to generate RINs if your organization is a 

Domestic Renewable Fuel Producer, a Renewable Fuel Importer, or a bonded Foreign Renewable Fuel 

Producer. There are two different kinds of RIN generation, generating as an importer and generating as a 

producer. To generate RINs as a producer, either click the Generate button or select Generate in the "I 

want to..." drop-down and click Go. Doing so takes you to the first page (Report Fuel) of the three-step 

Generate Wizard (see Figure 13). 
EMTS User's Guide

December 2011

Page 12

Figure 13: Generate Wizard, Report Fuel Page (Step 1)

The green boxes on the right side of the page indicate which of the three generate steps you are completing. 

All fields that are marked with a red asterisk are required. In the drop-down fields, the invalid options are 

grayed out. For example, in Figure 14, the organization can produce only Advanced Biofuel, Renewable 

Fuel, and Cellulosic Diesel, so the remaining Fuel (D Code) options are grayed out. 
EMTS User's Guide

December 2011

Page 13

Figure 14: Drop-down Example for Generate Wizard

Once you have completed all of the required fields, click Report Feedstocks at the bottom of the page to 

move to the second page of the Generate Wizard. If all of the information on the Report Fuel page is valid, 

you will be redirected to the Report Feedstocks page. Otherwise, you will remain on the Report Fuel page, 

and you will see a list of QA Check Errors at the top of the page (see Figure 13). Once you correct the 

errors, you will be able to move to the Report Feedstocks page. 

Figure 15: QA Check Errors

On the Report Feedstocks page, you must enter all of the feedstocks used to generate the fuel specified on 

the Report Fuel page. To add a feedstock, you must populate the three required fields, check the checkbox 

for renewable biomass (when generating RINs, all feedstock(s) must meet the definition of 'renewable 

biomass'), and then click the Add button. In the Feedstock drop-down, the feedstocks that your 

organization is not registered for are grayed out. After you have clicked the Add button, the feedstock 

information will be displayed in the grid (see Figure 14).
EMTS User's Guide

December 2011

Page 14

Figure 16: Generate Wizard – Report Feedstocks Page (Step 2)

Once you have added all of the feedstocks used to generate the RINs specified on the Report Fuel page, click 

the Report Co-products button at the bottom of the page. The Report Co-products page, which is Step 3 of 

the Generate Wizard, behaves similarly to the Report Feedstocks page. You must add any co-products 

produced by your organization's fuel generation process. If there are no co-products to report, leave all 

fields blank. To complete the Generate Wizard, click the Add to Transaction Bin button. Note: In addition, 

parties must complete the RFS0701: RFS2 Renewable Fuel Producer Co-products Report and submit it 

quarterly. 

If your organization is a Renewable Fuel Importer, you have the option to generate RINs as an importer. 

The Generate Wizard for Importers is similar to the Generate Wizard for Renewable Fuel Producers, except 

when you identify the production source on the Report Fuel page, you must provide the originating 

organization and facility (the Importer’s organization and facility) and the generating organization and 

facility (the Foreign Producer’s organization and facility). The Foreign Fuel Producer Facility ID that you 

enter must be registered for the Process, Fuel (D Code), Fuel Category, and Feedstock that you enter,

otherwise QA checks will prohibit RIN generation. 

Foreign Fuel Producers that are identified by importers as the generating organization in a generate 

transaction can view the details of the transaction by selecting View Importer Transactions under the View 

Transactions menu option. The View Transactions page (see Figure 17) includes an overview of all of the 
EMTS User's Guide

December 2011

Page 15

generate transactions in which an importer has identified that organization as the generating organization. 

Selecting "View Details" for a transaction displays the details of the transaction. 

Figure 17: View Importer Transactions

Foreign Fuel Producers can also subscribe to the Foreign Producer RIN Generation notification. This 

notification is sent to the Foreign Fuel Producer every time an importer identifies their organization in a 

generate transaction. For information on how to subscribe to notifications, see the Receiving Notifications 

section of this document. 

Managing the Transaction Bin

After you click Add to Transaction Bin, you are taken to the Transaction Bin (see Figure 18). 
EMTS User's Guide

December 2011

Page 16

Figure 18: Transaction Bin

The Transaction Bin is organization-specific, so transactions added to the Transaction Bin by any of your 

organization's submitters will be displayed on the page. To switch the organization for which the 

Transaction Bin is displayed, click Select a Different Organization. 

For each transaction in the Transaction Bin, you have the option to View Details, complete another 

transaction of that transaction type (i.e., Generate RINs), or Remove the transaction (see Figure 19). 

Figure 19: Transaction Bin Options
EMTS User's Guide

December 2011

Page 17

If you select View Details, you will be taken to a page that displays all of the details of the transaction. This 

page can be used to verify the contents of the transaction before submitting it. If you select Generate RINs, 

you will be taken to the first page of the Generate Wizard so that you can complete an additional generate 

transaction before you submit the transactions from the Transaction Bin. If you select Remove, you will be 

taken to a page that contains the transaction details. At the bottom of the page, you will be able to click a 

Confirm Remove button. Doing so takes you back to the Transaction Bin, and the removed transaction is no 

longer available. 

Along with accessing the Transaction Bin at the end of each wizard, you can navigate to the Transaction Bin 

from multiple pages of the EMTS website using the Transaction Bin accordion tab on the right side of the 

page (see Figure 20). The tab contains the number of un-submitted transactions and a link to the 

Transaction Bin. 

Figure 20: Accessing the Transaction Bin

Clicking the View Transaction Bin link takes you to the Transaction Bin. Note that the RINs associated with 

each separate, sell, and retire transaction in the Transaction Bin are Reserved rather than Available (they 

show up in the Reserved column of the View RIN Holdings grid). As a result, these RINs may not be used 

for any other transactions. If a separate, sell, or retire transaction is removed from the Transaction Bin, the 

associated RINs return to an Available status. RINs associated with a generate transaction do not show up 

in the View RIN Holdings grid until the transaction is submitted from the Transaction Bin, and RINs 

associated with a buy transaction do not show up in the View RIN Holdings grid until the transaction is 

submitted from the Transaction Bin and accepted by the trading partner.

To complete a transaction, you must submit it from the Transaction Bin by clicking the Submit button at the 

bottom of the page. If you have multiple transactions in the Transaction Bin, you must submit all of the 

transactions at once. If you do not wish to submit one of the transactions in the bin, you can remove that 

transaction and submit the remaining transactions. 

Note: Submitting a transaction that is acting upon a large number of RIN batches may take several minutes, 

causing your browser to timeout. Please be patient and do not submit another transaction until the 

transaction has completed and your RIN Holdings and Transaction Bin reflect the results of that 

transaction. After you press Submit, you will be taken to a Confirm and Submit page, which displays an 

overview of the transactions you are about to submit. You must click the Confirm Submit button circled in 

Figure 21 to complete the submission. 
EMTS User's Guide

December 2011

Page 18

Figure 21: Confirm and Submit Page

 

Once you confirm the submission, the View RIN Holdings (Current) page will reflect the results of the 

submitted transactions, and the Transaction Bin will be empty. 

Note: Unconfirmed transactions in the Transaction Bin expire after five business days. At that point, the

transactions will be removed from the Transaction Bin, and all reserved RINs associated with expired 

separate, sell, and retire transactions will return to the “Available” state. 

Separating RINs

Assigned RINs may be separated from the Manage RIN Holdings page (see Figure 22). To separate RINs in 

your RIN Holdings, select Separate in the "I want to..." drop-down, and click Go. Doing so will take you to 

the first page of the Separate Wizard (see Figure 23). 

Figure 22: Separate Option for Available Assigned RINs
EMTS User's Guide

December 2011

Page 19

Figure 23: Separate Wizard – Identify RINs (Step 1)

The green boxes on the right side of the page indicate which of the two steps of the Separate Wizard you 

are completing. All fields marked with a red asterisk are required. The Fuel (D Code) and RIN Year fields 

are automatically populated with the information from the row of RINs in the RIN Holdings grid that you 

decided to separate. In the Reason for Separation drop-down, only the reasons that are applicable to your 

organization's registered business activities are enabled (the remaining options are grayed out). The 

Separate Wizard also contains a document grid; you can use this grid to specify the name and identifier of 

one or more documents that support the separate transaction. Note that the document itself cannot be

uploaded. To add document information to the grid, fill in the Document Type and Document Identification 

fields, and click Add (see Figure 24). 

Figure 24: Supporting Document Information

When you complete the Identify RINs page, click Advanced Options at the bottom of the page to navigate to 

the second step of the Separate Wizard (see Figure 25). On the Advanced RIN Selection page, you have the 

option to specify a batch of RINs to separate. If you do not wish to make any selections on this page (this 

step is optional), click Add to Transaction Bin at the bottom of the page to continue. In this situation, EMTS

will automatically separate RINs using the First-in, First-out (FIFO) accounting method (i.e., the oldest 

RINs, based on production date, are used first, for the RIN Year, Fuel Code, and Fuel Category chosen). 

Alternatively, you may use this page to identify a specific originating organization, or organization and 

facility, or organization, facility, and batch number. To specify an organization, click the originating 

organization's name, and press Select (see Figure 25). 
EMTS User's Guide

December 2011

Page 22

Figure 26: Selected Organization Example

To select a Facility, click the Facility tab of the Advanced RIN Selection accordion, and follow the same 

steps. Repeat the steps to identify a particular batch from a specified organization and facility. Once you 

have specified the originating source information, click Add to Transaction Bin to continue. After you 

submit the separate transaction from the Transaction Bin, your RIN Holdings grid will reflect the results of 

the separation. 

From your RIN Holding Account, you may also separate assigned RINs on behalf of a Small Blender by 

selecting the Separate (Upward delegation) option in the "I want to..." dropdown (see Figure 27). Doing so 

will take you to the first step of the Separate Wizard for upward delegation (see Figure 28).

Figure 28: Separate Wizard – Identify RINs (Step 1)

In the first step of the Separate Wizard for upward delegation, the Reason for Separation is pre-populated 

with "Upstream Delegation for Blending," and the page includes fields for the blender name and identifier. 

You must provide this information in order to separate for upward delegation. Apart from the Identify 

RINs section of Step 1, the Separate Wizard for upward delegation is identical to the Separate Wizard used 

for all other reasons for separation. 
EMTS User's Guide

December 2011

Page 25

Small Blenders that are identified in separate transactions for upward delegation can view the details of 

those transactions by selecting View Blender Transactions under the View Transactions menu option. The 

View Transactions page (see Figure 29) includes an overview of all of the separate transactions in which 

that organization has been identified as the blender. Selecting "View Details" for a transaction displays the 

details of the transaction. 

Figure 29: View Blender Transactions

Small Blenders can also subscribe to the Small Blender RIN Separation notification. This notification is sent 

to the Small Blender every time their organization is identified in a separate transaction for upward 

delegation. For information on how to subscribe to notifications, see the Receiving Notifications section of 

this document. 

Retiring RINs

From your RIN Holding Account, you can retire assigned or separated RINs. If your organization is an 

obligated party (a Non-renewable Fuel Importer or a Refiner) or a renewable fuel exporter, your 

organization may retire separated RINs for obligation (Retire (Obligation)) and assigned or separated RINs 

for other reasons (Retire (Other)) (see Figure 30). For organizations with any other business activities (i.e., 

non-obligated parties), the only enabled retire option in your RIN Holdings grid will be Retire (Other) (see 

Figure 31).

Figure 32: Retire (Other) Wizard – Identify RINs (Step 1)

The green boxes on the right side of the page indicate which of the two steps of the Retire Wizard you are 

completing. All fields marked with a red asterisk are required. The Fuel (D Code), RIN Year, and 

Assignment fields are automatically populated with the information from the row of RINs in the RIN 

Holdings grid that you decided to retire. In the Reason for Retire field, only the reasons that are applicable 

to your organization's registered business activities are enabled (the remaining options are grayed out). 

The Retire Wizard also contains a document grid you can use to specify the name and identifier of one or

Page 28

more documents that support the retire transaction. Note that the document itself cannot be uploaded. To 

add document information to the grid, fill in the Document Type and Document Identification fields, and 

click Add. Doing so will add a row to the documents grid (see the Separating RINs section for more details).

When you complete the Identify RINs page, click Advanced RIN Selection at the bottom of the page to 

navigate to the second page of the Retire Wizard. On the Advanced RIN Selection page, you have the option 

of specifying the batch of RINs that you wish to retire. If you do not wish to make any selections on this 

page, click Add to Transaction Bin at the bottom of the page to continue. In this situation, EMTS will 

automatically retire the RINs in your RIN Holding Account using the FIFO accounting method. 

Alternatively, you may use this page to identify a specific originating organization, or organization and 

facility, or organization, facility, and batch number. See the Separating RINs section for details on how to 

use the Advanced RIN Selection page to specify originating source information. Once you have specified 

the originating source information, click Add to Transaction Bin to continue. After you submit the retire 

transaction from the Transaction Bin, the RINs will be removed from your RIN Holdings. 

Obligated parties can retire separated RINs for obligation by selecting the Retire (Obligation) option in the 

"I want to..." drop-down on the Mange RIN Holdings page. To view the total number of RINs your 

organization has retired for obligation, select Compliance Data under the Reports main menu option. On 

the View Aggregate RINs Retired for Obligation page (see Figure 33), the retired RIN quantities are 

aggregated by Fuel Code, RIN Year, Compliance Year, and Compliance Level. For Refiners with a “Refinery 

by Refinery” compliance level, the RIN quantities are also aggregated by Facility. For organizations that 

have not retired any RINs for obligation, the grid on this page will be empty. 

Figure 33: View Aggregate RINs Retired for Obligation

Trading RINs 

You can initiate a trade from your RIN Holdings page. To initiate a sell transaction, you must have RINs in 

your RIN Holdings. For a row of RIN data in your RIN Holdings grid, select Sell in the "I want to..." dropdown, and click Go. Doing so will take you to the first page of the Sell Wizard (see Figure 34).

Figure 35: Sell RINs – Select Trading Partner

When you have selected your trading partner, click the Transaction Details button to move to the next page. 

On the Sell RINs – Transaction Details and Documents page, you must enter the Transfer Date, Price Paid 

(either price per RIN or price per gallon), and Sell Reason. The value entered for Price Paid must have 

exactly two digits after the decimal place. 

You may also enter a Matching Transaction Identifier. This element allows users to accept specific buy/sell 

transactions in the case of several similar transactions. It is the unique transaction identifier assigned by 

EMTS to an initiated trade. When accepting a trade, users can include this element in the trade matching 

criteria (along with the other trade matching criteria currently in effect). If this element is reported, EMTS 

will attempt to locate a matching transaction based on the MatchedTransactionIdentifier and the other 

matching criteria provided. If a match is not found, then the transaction will fail. If this element is not 

reported, then it will not be used in the trade matching (but all other required matching elements will still 

apply).
EMTS User's Guide

You can also provide a Product Transfer Document (PTD) number and other additional information. The 

Transaction Details and Documents page contains a document grid you can use to specify the name and 

identifier of one or more documents that support the sell transaction. Note that the document itself cannot 

be uploaded. To add document information to the grid, fill in the Document Type and Document 

Identification fields, and click Add (see the Separating RINs section for more details). When you have 

completed this page, click Advanced RIN Selection to move to the final page of the Sell Wizard. 

On the Advanced RIN Selection page, you have the option of specifying the batch of RINs that you wish to 

sell. If you do not wish to specify originating source information, click Add to Transaction Bin at the bottom 

of the page to continue. In this situation, EMTS will automatically sell the RINs in your RIN Holding 

Account using the FIFO accounting method. Alternatively, you may use this page to identify a specific 

originating organization, or organization and facility, or organization, facility, and batch number. See the 

Separating RINs section for details on how to use the Advanced RIN Selection page to specify originating 

source information. Once you have specified the originating source information, click Add to Transaction 

Bin to continue. After you submit the sell transaction from the Transaction Bin, the transaction will be in a 

pending state, and the RINs associated with the sale will be in the Pending column of the RIN Holdings grid 

(see Figure 36). The RINs will remain in the Pending column until the trading partner accepts the sell 

transaction. 

Figure 36: Pending RINs in RIN Holdings Grid 

To initiate a buy transaction, go to the Manage RIN Holdings page, and either click the Buy button below the 

RIN Holdings grid or select Buy in the "I want to..." drop-down for a row in the RIN Holdings and click Go. If 

you select Buy for an existing row in the RIN Holdings grid, the Fuel (D Code), RIN Year, and Assignment in 

the Buy Wizard will be pre-populated with information from that row. 

The green boxes on the right side of the page indicate which of the three steps you are completing. All 

fields marked with a red asterisk are required. On the Identify RINs page, you must provide the Fuel (D 

Code), RIN Year, Assignment, and Quantity of RINs. 

You may also enter a Matching Transaction Identifier. This element allows users to accept specific buy/sell 

transactions in the case of several similar transactions. It is the unique transaction identifier assigned by 

EMTS to an initiated trade. When accepting a trade, users can include this element in the trade matching

criteria (along with the other trade matching criteria currently in effect). If this element is reported, EMTS 

will attempt to locate a matching transaction based on the MatchedTransactionIdentifier and the other 

matching criteria provided. If a match is not found, then the transaction will fail. If this element is not 

reported, then it will not be used in the trade matching (but all other required matching elements will still 

apply).

You also have the option of using the Advanced Options fields to specify originating source information for 

the RINs that you wish to buy. To access the Advanced Options fields, click the Advanced Options tab 

circled in Figure 37. 

Figure 37: Buy RINs – Identify RINs Page (Step 1)

Once you click this tab, you will be able to access the Advanced Options fields (see Figure 38). 

Figure 38: Buy RINs – Advanced Options
EMTS User's Guide

December 2011

Page 33

To specify the originating source for a buy transaction, you will need to know the Generating Organization 

Identifier, the Generating Facility Identifier, and the Batch Number (unlike the Sell Wizard where you have 

options available to you). Once you complete the Identify RINs page of the Buy Wizard, click Select Trading 

Partner. The Select Trading Partner and the Transaction Details and Documents pages of the Buy Wizard

have the same behavior as the corresponding pages in the Sell Wizard. From the Transaction Details and 

Documents page, click Add to Transaction Bin. Submit the transaction from the Transaction Bin to 

complete the buy transaction. At this point, the transaction will be in a pending state, but the transfer of 

RINs will not be reflected in your RIN Holdings grid until the trading partner accepts the buy transaction. 

To view the pending transaction(s) that your organization has initiated or received (as the result of another 

organization initiating a transaction with your organization as the trading partner), hover over Trades on 

the main menu and select Review Trades. The Review Trades page is organization-specific (see tabs in 

Figure 39), so to switch the organization for which the page is displayed, open the Organizations tab of the 

accordion on the right side of the page, and click Select a Different Organization.

Figure 39: Review Trades Page

The Review Trades page includes a number of filter options that you can use to search for specific initiated 

or received buy or sell transactions. The labels on the Pending Transactions tabs include the number of 

transactions within each tab. In Figure 40, the organization has two Pending Initiated Transactions and 

zero Pending Received Transactions. In the Review Trades accordion, only one tab can be open at a time,

so to open the Pending Received Transactions tab of the accordion, you would click Pending Received 

Transactions. As a result, the Pending Initiated Transactions tab would close. 

For Pending Initiated Transactions, you can select View Details in the "I want to..." drop-down to view the 

details of the transaction, or you can select Cancel Offer to cancel the trade (see Figure 40). If you choose 

Cancel, you will be asked to confirm the cancellation, and the transaction will no longer appear in your 

Pending Initiated Transactions (or your trading partner's Pending Received Transactions). 

Figure 40: Pending Initiated Transactions Options

For Pending Received Transactions, you can select View Details, Accept Offer, or Deny Offer in the "I want 

to..." drop-down (see Figure 41). 

Figure 41: Pending Received Transactions Options

If you deny the offer, you will see the details of the transaction that you are denying, and you will need to 

provide an explanation for denying the trade (see Figure 42). Once you press Confirm Deny, the 

transaction will no longer appear in your Pending Received Transactions (or your trading partner's 

Pending Initiated Transactions).

If you select Accept Offer, you will also see the details of the transaction, and you will be asked to provide 

the price of the transaction (see Figure 43). Additionally, you will have the option of adding transaction 

details and document information. Note that the document itself cannot be uploaded. To add document 

information to the grid, fill in the Document Type and Document Identification fields, and click Add (see the 

Separating RINs section for more details).

Figure 43: Accept Trade Page

To report a PTD number for your transaction, enter the number in the "PTD" field. If you do not enter a 

PTD number, your transaction details will not include a PTD number. Note that this field is not 

automatically carried over from your trading partner's transaction.

Once you click Confirm Accept, the transaction will no longer appear in your Pending Received 

Transactions (or your trading partner's Pending Initiated Transactions), and the results of the trade will be 

reflected in your RIN Holdings. 

If you select View Details for a Pending Received transaction, you will see the details of the transaction 

along with the option to either accept the trade or deny the trade. Clicking Deny Trade will take you to the 
EMTS User's Guide

December 2011

Page 38

Deny Trade page (see Figure 42), and clicking Accept Trade will take you to the Accept Trade page (see 

Figure 43). 

If a trade is not accepted, cancelled, or denied within ten business days of the submission date (the date 

that you or your trading partner initiated the trade), the trade will expire, and it will no longer appear on 

your Review Trades page. 

As described earlier in this section, a trade can be completed if one trading partner initiates a trade through 

a Buy/Sell Wizard, and the other partner then accepts the initiated trade from the Review Trades page. 

Trades can also be completed in the following ways: 

● Both trading partners submit XML files for a trade (one buy and one sell); 

● One trading partner completes a buy/sell transaction on the web application, and the other trading 

partner submits a matching XML file for the corresponding transaction; or

● One trading partner completes a buy transaction on the web application, and the other trading 

partner completes a matching sell transaction on the web application. 

In all of these instances, the following fields must match for the trades to match:

1. RIN Year;

2. Fuel Code;

3. RIN Quantity;

4. Reason Code;*

5. Assignment Code; 

6. Transaction Date; and

7. RIN Price Amount or Gallon Price Amount Element.**

* If the buy or sell reason is Deny Trade or Cancel Trade, then the Reason Codes do not need to 

match.

** The values reported for these elements are not required to match.

In addition:

1) The Trading Partner Organization Identifiers must agree (e.g., the sell transaction should list 

the buying organization as the Trading Partner, and the buy transaction should list the selling 

organization as the Trading Partner); and 

2) If one Trading Partner specifies Originating Source information, then the other Trading Partner 

must specify the same Originating Source information. 
EMTS User's Guide

December 2011

Page 39

If these fields do not match, then the trades submitted by both trading partners via XML or web application 

will be considered pending initiated trades. For the Price Element matching criteria, both trading partners 

must provide either RIN price amount or gallon price amount (the same element), but the values reported 

do not need to match. For more information on using XML files to interact with EMTS, see the Submitting 

XML Files Section.

Managing the Blocked List

In some cases, you may wish to ensure that your organization does not buy RINs that were generated by a 

specific renewable fuel producer or at a specific facility. To do so, you can add a producer or facility to your 

organization's Blocked List. When a trade includes RINs that originated from a producer or facility on the 

buying organization's Blocked List, the transaction will automatically be denied by EMTS. You can access 

your organization's Blocked List by selecting View Blocked List under Organization in the EMTS main 

menu. 

Figure 44: View Blocked List Page

From the View Blocked List page (see Figure 44), click the Add Blocked Producer or Add Blocked Facility 

button to add a producer or facility to your organization's Blocked List. Clicking Add Blocked Producer 

takes you to the Add Producer to Blocked List page (see Figure 45). On the Add Producer to Blocked List 

page, you must identify a renewable fuel producer from a list of organizations (the list includes only 

renewable fuel producers). You can filter the list by Organization Name or Organization ID. To select a 

producer to add to your Blocked List, click the organization name in the list, and press Select. In Figure 43, 

the organization list was filtered with the word "Better," and Better Fuel Corporation was selected.

EMTS User's Guide

December 2011

Page 41

Figure 46: View Blocked List Grid

When you add a producer to your organization's Blocked List, the Facility column in the View Blocked List 

grid will contain the text "All facilities," indicating that your organization has chosen to block RINs that 

originate at all of the producer's facilities. If you add a facility to the Blocked List, the Facility column will 

display the name of the facility that you have blocked, and the Organization column will display the name of 

the organization associated with that facility. 

For each row in the View Blocked List grid, you have the option to either View Details or Remove. Selecting 

View Details takes you to a View Blocked List Details page that includes the Organization, Facility, and Date 

Blocked information displayed in the grid along with the name of the person that added the 

organization/facility to the Blocked List and the comment provided with the action. Selecting Remove 

takes you to a Confirm Removal page (see Figure 47). The page displays all of the information included on 

the View Details page. You must press Confirm Remove at the bottom of the page to remove the 

organization/facility from the Blocked List. Upon doing so, you will return to the View Blocked List grid, 

and the removed organization/facility will no longer be included in the grid.

Submitting XML Files

If you wish to submit data to EMTS without using the website transaction wizards, you may do so by 

submitting valid XML files from the EMTS web application, a personal node, or a node client. For more 

details on XML file submission, please go to http://www.exchangenetwork.net/exchanges/air/emts.htm and

download the implementation resources available on the site. The Flow Configuration Document (FCD) 

describes the different methods of file submission and contains details on the Exchange Network Header 

v2.0, which must be included in an XML file for it to be valid. The XML Schema and Data Exchange 

Template provide additional information on the structure and content requirements for a valid XML file. 

Please see the Sample XML Instance File for an example of a valid XML file. 

To assist EMTS users with constructing XML files, EPA has developed the EMTS Conversion Tool (ECT). 

The ECT has the capability to convert user-populated Excel or delimited files to XML files. The ECT also 

provides blank templates for each transaction type for users to populate, and then it converts the 

populated templates to XML files. The ECT and related materials can be downloaded from the EMTS web 

page located at http://www.epa.gov/otaq/fuels/renewablefuels/epamts.htm . 

Once you have created an XML file that you would like to submit to the EMTS node through the web 

application (for node and node client submissions, see the FCD), return to the EMTS website, hover over 

Submissions on the main menu, and click Submit File. The Submit File page is user-specific, so if you 

represent multiple organizations, you can submit files for all of your organizations from the Submit File 

page without changing the organization that you represent. From this page, you may submit only one XML 

file at a time. The file can contain multiple transactions, but the transactions may not be dependent upon 

one another (i.e., you cannot submit a file that contains a generate transaction followed by a separate 

transaction that separates the RINs generated in the file). On the Submit File page (see Figure 51), click the 

Browse button to identify the XML file you would like to submit. The file must include the Exchange 

Network Header v2.0 and must pass EMTS v1.0 XSD schema validation for it to be submitted to the EMTS 

node. 

Figure 51: Submit File Page
EMTS User's Guide

December 2011

Page 47

Once you have identified a file, press the Submit button. After clicking the Submit button, it may take some 

time to process and load the file into EMTS, so please be patient, and avoid clicking the Submit button 

again. The file must first pass through the CDX node before it can be processed by the EMTS node. If your 

file does not pass schema validation, you will receive an error message on the Submit File page. If your file 

is valid, the message on the Submit File page will be updated to indicate that your file has been submitted.

The Submit File History page (see Figure 53), like the Submit File page, is user-specific (not organizationspecific), so it will include records for your submissions for all of your organizations. It will display 

information only for files submitted from the Submit File page and not for files submitted using a personal 

node or node client. If the Received By CDX column displays Yes for a submission, the submission was 

successfully received by the CDX node and has been sent to the EMTS node for processing. To view the 

EMTS node results for the file submission, hover over the Submissions menu option, and click View Node 

Submissions. The View Node Submissions page (see Figure 54)displays the results of XML files submitted 

from a personal node or node client along with XML files submitted from the Submit File page, which acts 

as a node client.

View Node Submissions grid. To switch organizations, click Select a Different Organization in the 

Organizations tab of the accordion. To filter the View Web Submissions grid to look for a particular 

submission, use the options in the Search box, and press Filter. 

The Submission Status column of the View Node Submissions grid displays the EMTS node status of each 

XML file submission. A status of Processed indicates that the file passed all QA checks, and a status of 

Failed indicates that the file failed one or more EMTS QA checks. For processed and failed files, you can 

select View Details in the "I want to..." column to see more information about the submission and a list of 

transactions within the submission (see Figure 55).

From the submission details page, you will be able to view transaction details for each transaction in the 

submission. From the View Node Submissions page, you can also select QA Results in the "I want to..."

column for a failed submission. This will take you to a QA Feedback Report, which contains a list of QA 

checks that the submission failed. 

To access the QA Feedback document for a failed submission, go to the View Node Submissions page (select 

View Node Submissions under the Submissions menu option). Note that the "immediate" QA Feedback 

document is created on a scheduled basis, so in reality, the document will be available shortly after a failed 

submission rather than immediately after the submission. 

To download the QA Feedback document for a submission with a Current Status of "Failed," select 

Download QA and press the Go button (see Figure 56). You will be prompted to either open or save the ZIP

Receiving Notifications

EMTS can communicate information to users by sending notifications via email. Some notifications will be 

sent immediately while others will be aggregated and sent nightly. The current version of EMTS includes a 

number of immediate notifications, such as the EMTS Trade Cancelled notification and the EMTS Trade 

Denied notification, along with several aggregated daily notifications, such as the EMTS Notification of 

Pending Trades and the Daily Processed Document Summary. For a complete list of notifications, see 

Appendix E of the Flow Configuration Document, which can be downloaded from the Exchange Network 

website http://www.exchangenetwork.net/exchanges/air/emts.htm.

that have reached their final status (completed, cancelled, expired, or denied) within the past 10 

calendar days. 

● Expired Trades: This nightly document lists all pending trades that will expire within 1 business 

day as well as all trades that have expired within the past 10 calendar days. 

 

● Monthly Transaction History: This document, available on a monthly basis, lists all generate, 

separate, buy, sell and retire transactions submitted by an organization through XML files or the 

EMTS web interface during the prior month. 

● Pending Trades: This document, available on a nightly basis or three times per day, lists the details 

of all pending initiated and pending received trades for an organization. 

● Pending Trade Details: This document, available on a nightly basis or three times per day, lists the 

RIN batch details of all pending initiated and pending received trades for an organization. 

● QA Feedback: This immediate document shows the failed QA check results for a given failed

● Transaction Status: This document, available nightly, includes transaction activity for the previous 

day.

The Monthly Transaction History document is created for the prior month’s transactions on the first 

Saturday of every month. Once the prior month’s Monthly Transaction History document is created, the 

Cancelled Trades, Completed Trades, Expired Trades, Pending Trades, Pending Trade Details, and 

Transaction Status documents for that month are purged. 

To download the documents from the EMTS website or retrieve them using a personal node or node client, 

you must first subscribe to them from the Manage Subscriptions page (see Figure 57) (click Manage

When are the quarterly reports available?

Quarterly reports will be available to download within ten business days of the end of a quarter. An email 

notification will be sent when the quarterly reports are available to download from the EMTS website. To

subscribe to the “Quarterly Reports Available” notification, access the Manage Subscriptions page from the 

Reports menu on the EMTS web interface.

How do I subscribe to quarterly reports?

You must login to the EMTS web application to subscribe to quarterly reports. In the EMTS main menu, 

select Reports, and then select Manage Subscriptions. 

All of the reports are available in PDF format. In addition, the RFS2 EMTS RIN Generation Report and the 

RFS2 EMTS RIN Transaction Report are available in XML and CSV format. You can subscribe to the PDF 

format and either the XML or the CSV format if you wish. Subscriptions are organization specific, so all 

submitters for an organization can download the reports.

To change the subscription for a quarterly report, click the Go button in the "I want to..." column for the 

report. On the Manage Subscription page for that report, check or uncheck the "Subscribed" box (see Figure

How do I create a Transaction Error Report?

The RFS2 EMTS Transaction Error Report is used to report discrepancies that exist between the EMTS and 

your organization's internal record-keeping system. You can report transaction errors following the end of 

the quarter. You must report all transaction errors by the due date for quarterly reports. Note that the 

quarterly report submission deadline is two months after the quarter ends. When you have entered and 

submitted your transaction errors, EMTS will create a Transaction Error Report for your organization. If 

you do not enter any errors or if you do not submit the reported errors, EMTS will not generate a 

Transaction Error Report for your organization. Once a Transaction Error Report is generated for your 

organization, it cannot be changed in any way.

You must login to the EMTS web application to report transaction errors. In the EMTS main menu, select 

Reports, and then select Transaction Errors. If the compliance period is closed or you have previously 

submitted a Transaction Error Report for the quarter, you will see a message indicating that transaction 

error reporting is not available. If the Compliance period is open and you have not yet submitted a 

Transaction Error Report for the quarter, press Continue. 

On the View Reported Errors page, you can add transaction errors to the Reported Errors grid (see Figure 

65). If you have already entered errors for the quarter, but have not yet submitted them, you can view and 

edit the errors on this page.

The Transactions grid will display your organization’s transactions that match the search criteria. The "I 

want to..." dropdown will contain the Identify Error option for transactions without previously reported 

errors and the Edit Details and Remove options for transactions with previously reported errors. To report 

an error for a transaction without a previously reported error, press Go in the "I want to..." column. 

On the Identify Transaction Errors page, you can view the details of the transaction by clicking the "+" on 

the Transaction Details panel (see Figure 67).

Provide an explanation of the error(s) in the "Explanation of Errors" field, and add any additional 

information in the "Document Information" field (optional), then click Save. You will then return to the 

View Reported Errors page, and the error will appear in the Reported Errors grid. On the View Reported 

Errors page, you can use the filters to search for transactions for which you have already reported errors. 

To edit the details of an error that you have already reported, select Edit Details in the "I want to..." dropdown menu. The Identify Transaction Errors page will display the details that you previously provided. 

Click Save to keep any updates.

To remove an error from the Reported Errors grid, select Remove in the "I want to..." drop-down menu. 

The Confirm Remove page will display the transaction details and reported errors. Click Remove to 

confirm removal of the error.

Once you have reported all transaction errors for the quarter, press Submit Errors on the View Reported 

Errors page. After you press the Submit button, you must confirm the transaction errors (see Figure 68).

Figure 68: Confirm Transaction Errors

Once you confirm the transaction errors, EMTS will generate your organization’s Transaction Error Report, 

and you will no longer be able to add or edit transaction errors for the compliance period. EMTS will 

generate the report within one business day of your confirmation. At that time, the Transaction Error 

Report will be available for you to download from the View Reports page (select View Reports under the 

Reports menu option). To download the Transaction Error Report, select Download Document in the "I 

want to..." drop-down menu. Note that if the "I want to..." column for the report says "No valid actions," the 

report is not yet available to be downloaded. When you select Download Document and press Go, you will 

see a window asking you to either open or save the ZIP file (see Figure 69). After you open the ZIP file, you 

will be able to access the PDF report.

Which transactions are included in the quarterly reports?

The reports include transactions that were submitted and completed during the quarter. Thus, generate, 

buy, and sell transactions with a generation date or transaction date in one quarter and a submission date 

in another quarter will be included in the quarterly reports from the quarter that contains the submission 

date. Retire and separate transactions are always included in the report from the quarter during which 

they were submitted. 

How do I submit quarterly reports?

You must submit your reports through the DC Fuels application, which is accessed through MyCDX. For 

more information, visit http://www.epa.gov/otaq/regs/fuels/rfsforms.htm. You are required to submit the 

reports in PDF format within two months of the end of the quarter. Note that the XML and CSV versions of 

the quarterly reports should be used for verification purposes only. 

Are examples of the quarterly reports available?

For examples of the quarterly reports, please see the document "EMTS Quarterly Reports - Getting Started

Guide."

Annual Reports

EMTS generates two organization-specific annual reports, both of which are provided in PDF format. The 

RFS2 EMTS Annual Report shows details for every RIN batch that an organization has retired for 

compliance, and the RFS2 EMTS Annual Statement shows aggregate values for the number of RINs an 

organization has retired for compliance. 

Users must be subscribed to the reports to be able to download them after they are generated by EMTS. 

Subscriptions are organization specific, so all submitters for an organization can download the reports. 

You can subscribe to the annual reports on the Manage Subscriptions page by selecting Manage 

Subscriptions under Reports on the EMTS main menu. 

To change the subscription for an annual report, click the Go button in the "I want to..." column for the 

report. On the Manage Subscription page for that report, check or uncheck the "Subscribed" box.

To download the annual reports, you must login to the EMTS web application. In the EMTS main menu, 

select Reports, and then select View Reports. The View Reports page displays all of the reports to which 

your organization has subscribed. For the annual report that you wish to download, select Download 

Document in the "I want to..." drop-down menu and click the Go button. Note that if the "I want to..."

column for a report says "No valid actions," the report is not yet available to be downloaded. You will be 

prompted to open or save the ZIP file (see Figure 67). You must open the ZIP file to extract the report. 

EMTS quarterly reports are provided in PDF format. 

Agent Reports

EMTS users registered as Agents in the OTAQ Registration system see an additional menu item in the EMTS 

main menu called “Agents.” This tab includes the option to subscribe and download EMTS documents for 

all of their associated organizations, rather than having to switch organizations and download each 

organization’s documents separately. The .ZIP files contain all EMTS documents – daily, three per day, 

weekly, and monthly – for all organizations associated with the Agent. Note that the. ZIP file will only 

include documents that have active subscriptions. Quarterly reports are not available as Agent Reports. 
EMTS User's Guide

To subscribe to Agent reports, click the “Agent” menu item in the main menu (only visible to registered 

Agents), and select “Manage Subscriptions” (see Figure 70).

Open the compressed .ZIP file to access the documents. When Agent Reports are downloaded, EMTS will 

automatically update the 22-day subscription expiration clock for each document included in the .ZIP file. If 

an Agent is associated with an organization in a submitting role other than “Agent,” that organization’s 

documents will not be included in the Agent Reports. It is still possible to access documents for individual 

organizations without retrieving documents for all organizations associated with an Agent.
