IMPORTANT REMINDER: 

Regulated parties are urged to conduct due diligence investigations and 

exercise caution when conducting Renewable Identifcation 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 specifed 

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. 

Access to EMTS requires registration with both the Central Data Exchange (CDX) and OTAQ Fuels. For 

instructions on setting up these accounts, see the “Getting Started – MyCDX” and “To Add DC FUELS Program”

documents under Registration on the EMTS Documents website. You can access the EMTS website only 

through the 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" on the EMTS Documents 

website for further instructions. 

Figure 1: OTAQ EMTS Application Link 

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

Selecting an Organization 

Upon accessing the EMTS Home screen, 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 screen -- "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 screens (see Figure 4). 

RFS EMTS User’s Guide 2 
 

 

 

 

 

 

 

 

December 2017 

Figure 4: Organizations Accordion Tab 

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

● Home screen; 

● 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 screen 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 Organization Affiliations. On the View Organization Affiliations 

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

Registration application. A Search feature is provided that allows you to search your affiliated organizations

by Organization Identifier, Organization Name, User Role, or Agent. 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 screen 

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 screen displays your organization’s 

registered business activities, users and their roles, and facilities. From this screen, you can view the details 

RFS EMTS User’s Guide 3 
 

 

 

 

December 2017 

for the organization’s registered facilities. Choosing the View Registered Data option will take you to the 

View Registered Data screen for the selected organization (see Figure 5). 

Figure 5: View Registered Data 

The View Facility Data screen displays the Facility, Identifier, Address, Total Capacity – Baseline Volume 

Total Capacity – Actual Peak, and Registered Co-products (see Figure 6).

Figure 6: View Facility Data 

To view the pathways associated with your facility click “View Pathways”. Users can search for a specific 

pathway The View Registered Pathways screen displays the Facility, Fuel(D Code), Fuel Category, Process, 

Feedstock, QAP Provider, QAP Service Type, and if the Pathway is suspended (see Figure 7). 

Figure 7: View Registered Pathways 

RFS EMTS User’s Guide 5 
 

 

 

 

 

 

December 2017 

To view the Pathway Details select the View Pathway Details from the drop-down and click “Go”. Users can 

view the QAP Provider, QAP Service Type, Coverage Start Date, Coverage End Date, Fuel (D Code), Fuel

Category Code, Process Code, Feedstock Code, Activated by EPA, If the Pathway is Suspended, and if it was 

suspended the Suspend Date (see Figure 8). 

Figure 8: View Pathway Details 

You can only view your facility and pathway data in EMTS; you cannot make edits to the data in EMTS. 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 screen is organization-specific (indicated by the organization

name above the RIN Holdings grid, circled in Figure 9 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." 

RFS EMTS User’s Guide 6 
 

 

 

 

 

 

 

 

December 2017 

Figure 9: Manage RIN Holdings Screen 

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

transactions, the RIN Holdings grid will be empty (see Figure 9). 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 10 for an example). Each row in the RIN Holdings

grid represents a unique combination of Fuel (D Code), RIN Year, Assignment, and QAP Service Type. 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.

Various sorting and filtering capabilities allow you work with this RIN data. For example, you can arrange 

data in order to compare the total number of RINs EMTS has processed in your account to your own off-line

transaction records. These data are also available for download in a variety of formats. 

RFS EMTS User’s Guide 7 
 

 

 

 

 

 

December 2017 

Figure 10: 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,

Assignment, and QAP Service Type 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. This opens the View RIN Holding Details screen (see Figure 11). 

RFS EMTS User’s Guide 8 
 

 

 

 

 

 

 

December 2017 

Figure 11: View RIN Holding Details Screen 

The View RIN Holding Details screen 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, 

QAP Service Type and Assignment that you selected on the RIN Holdings screen. 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 Transaction opens the screen that details the last transaction that acted on that 

RIN batch. Selecting View Details opens the RIN Batch Details screen, where you will have access to 

information such as fuel category code, equivalence value, originating organization, and facility. From the 

Batch Details screen, you may also select "Transaction" next to any batch of RINs to access the same 

aforementioned screen. For available RINs, the "I want to..." drop-down options are View Details, 

Transaction, and Lock RINs. Selecting Lock RINs opens the Lock RINs Confirmation screen (see Figure 12).

December 2017 

Figure 12: Lock RINs Confirmation Screen 

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

After you enter a comment and click Confirm, you will return to the View RIN Holding Details screen. 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. 

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 screen, the Unlock RINs Confirmation 

screen 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. 

To lock or unlock multiple batches of RINS, hover over RINs on the main menu and click Lock RIN Batches 

(see Figure 13). 

RFS EMTS User’s Guide 10 
 

 

December 2017 

Figure 13: Select Lock RIN Batches 

The Lock RIN Batches screen allows you to lock batches of RINs by organization, facility, RIN batch or QAP 

Provider. RIN Year, under Basic Filter Options is a required search field. In the example below, the 

organization was selected (RAP Inc. Gen Biodiesel) as well as the facility (Valley Medico Plant 12) (see 

Figure 14). By clicking the search button, all batches that originated at the Waynesboro facility will appear 

in the grid at the bottom of the screen (see Figure 15). 

Figure 14: Lock RIN Batches

Figure 15: Lock RIN Batches 

In the status column, you can see that the RINs in the grid are “Available.” To lock all of these RIN batches 

at one time, click the Lock All button (see Figure 15). 

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 16): 

Figure 16: Select View Expired RIN Holdings 

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

the screen). 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 screen, and click "Select a Different Organization." 

RFS EMTS User’s Guide 12 
 

 

 

 

 

 

 

 

December 2017 

If you view the RIN Holdings screen 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, Assignment Code, and/or QAP

Service Type select the filter options and click Filter (see Figure 17). 

Figure 17: 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 screen, 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 (Producer) button or select Generate as 

a Producer in the "I want to..." drop-down and click Go. This opens the first screen (Report Fuel) of the threestep Generate Wizard (see Figure 18). 

RFS EMTS User’s Guide 13

Figure 18: Generate Wizard, Report Fuel Screen (Step 1) 

RFS EMTS User’s Guide 14 
 

 

 

 

 

 

 

 

 

December 2017 

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

The following information is required to generate RINs: 

● Type of fuel produced; 

● Code that specifies the process used to create the renewable fuel; 

● Date the renewable fuel was produced; 

● Renewable fuel type as defined in Part M Section 80.1426; 

● QAP Service Type for the RINs; 

● Volume of renewable fuel produced; 

● Volume of denaturant added to the renewable fuel (ethanol only); 

● Number of RINs associated with the renewable fuel; 

● Facility ID; 

● Batch number; 

● Codes for all feedstocks used to produce the renewable fuel; 

● Quantity of all feedstocks used to produce the renewable fuel; 

● Units of measure for all feedstock quantities; 

● Affirmation that each feedstock meets the definition of renewable biomass; and 

● Codes for all co-products produced along with the renewable fuel, if there are any. 

All required fields are marked with a red asterisk. In the dropdown fields, the invalid options are grayed out.

For example, in Figure 19, the organization can produce only Advanced Biofuel, Renewable Fuel, and 

Cellulosic Diesel, so the remaining Fuel (D Code) options are disabled. 

You are not required to report an equivalence value. EMTS will automatically calculate the equivalence value 

based on the type of fuel for which you are generating RINs. The number of RINs you are allowed to generate

for a specific fuel type will be determined by the volume of the batch of fuel multiplied by the equivalence 

value. EMTS checks that the RINs you generate do not exceed your fuel volume by the equivalence value 

multiplier. If you report an equivalence value, EMTS will re-calculate and check this value. 

In the panel for Remedial Action, the “Is this an authorized Remedial Action” checkbox is used to indicate

that you are submitting a transaction for a “missed RIN generation” that has been authorized by EPA. The 

following fields must match the EPA authorization in the system to generate a “missed” batch of RINs: 

● Production Date; 

● RIN Quantity; 

● D Code; 

● QAP status; 

● Batch Number; 

● Originating Organization; 

● Originating Facility; and 

RFS EMTS User’s Guide 15 
 

 

 

 

 

December 2017 

● Import Facility (if applicable).Figure 19: Drop-down Example for Generate Wizard 

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

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

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

and you will see a list of QA Check Errors at the top of the screen (see Figure 20). Once you correct the errors, 

you will be able to move to the Report Feedstocks screen. 

Figure 20: QA Check Errors 

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

the Report Fuel screen. 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 dropdown, 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 21). 

RFS EMTS User’s Guide 16 
 

 

 

 

 

 

 

 

 

 

December 2017 

Figure 21: Generate Wizard – Report Feedstocks Screen (Step 2) 

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

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

of the Generate Wizard, behaves similarly to the Report Feedstocks screen. 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 screen, 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, Feedstock, and QAP Service Type 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 

Submissions menu. The View Transactions screen (see Figure 22) includes an overview of all of the 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. 

RFS EMTS User’s Guide 17 
 

 

 

 

 

December 2017 

Figure 22: 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, where transactions will be 

stored temporarily until you are ready for EMTS to process them (see Figure 23). 

RFS EMTS User’s Guide 18 
 

 

 

 

 

 

 

December 2017 

Figure 23: 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 screen. To switch the organization for which the

Transaction Bin is displayed, click Select a Different Organization. There is no restriction on the number of 

transactions that you can add to the Transaction Bin, provided they are originated on behalf of a single

organization and that organization has sufficient RINs in its RIN Holding Account. 

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 24). 

Figure 24: Transaction Bin Options 

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

screen 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 screen of the Generate Wizard so that you can complete an additional generate

transaction before you submit the transactions from the Transaction Bin. You cannot edit a transaction in 

the Transaction Bin; you must remove it and then create a new transaction. If you select Remove, you will be

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

a Confirm Remove button. This opens the Transaction Bin screen 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 screens of the EMTS website using the Transaction Bin accordion tab on the right side of the 

screen (see Figure 25). The tab contains the number of un-submitted transactions and a link to the 

Transaction Bin. 

Figure 25: Accessing the Transaction Bin 

Clicking the View Transaction Bin link opens the Transaction Bin screen. 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 screen. 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. In addition, if you have multiple transactions acting on

different RIN years, you need to select a RIN year before submitting your transactions from your Transaction 

Bin. For example, if you have multiple sell transactions in your Transaction Bin that will act on RIN batches 

for years 2011 or 2012, you must submit each year-specific batch separately. You may not submit all 

transactions across multiple years as part of a single transaction bin submission. 

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 click Submit, you will be taken to a Confirm and Submit screen, which displays an overview of the

transactions you are about to submit. You must click the Confirm Submit button circled in Figure 26 to 

complete the submission. 

RFS EMTS User’s Guide 20 
 

 

 

 

 

 

 

 

 

December 2017 

Figure 26: Confirm and Submit Screen 

Once you confirm the submission, the View RIN Holdings (Current) screen 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. For this reason, it is important that 

you complete your transactions as soon as possible to avoid loss of any transaction data that you have been

working on during multiple web sessions. 

Separating RINs 

Assigned RINs may be separated from the Manage RIN Holdings screen (see Figure 27). 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 screen of the Separate Wizard (see Figure 28).

December 2017 

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

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

are completing. The following information is required to separate RINs: 

● Renewable fuel code (D code); 

● Year the RINs being separated were generated; 

● QAP Service Type Code; 

● Number of RINs being separated; 

● Volume of fuel associated with the RINs being separated; 

● Date the RINs were separated; and 

● Code which specifies the reason for the separate transaction. 

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

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

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

organization's registered business activities are available (the remaining options are disabled). 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 29).

Figure 29: Supporting Document Information 

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

to the second step of the Separate Wizard (see Figure 27). On the Advanced RIN Selection screen, you have 

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

(this step is optional), click Add to Transaction Bin at the bottom of the screen 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, Fuel Category and QAP Service

Type chosen). Alternatively, you may use this screen 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 click Select (see Figure 30). 

RFS EMTS User’s Guide 23

Figure 31: 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..." drop-down (see Figure 32). Doing so 

will take you to the first step of the Separate Wizard for upward delegation (see Figure 33).

Figure 32: Separate (Upward delegation) Option for Available Assigned RINs 

Figure 33: 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 screen 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. 

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 screen (see Figure 34) 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.

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 

Depending on your organization's business activities you may choose to retire RINs for compliance or for 

other reasons from your RIN Holding Account. If your organization is an obligated party (a Non-renewable 

Fuel Importer, 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)). If your 

organization is registered as more than one type of obligated party, you must choose from the drop-down

the compliance level you would like to use (see Figure 35). 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 36).

Figure 36: Retire Options for a Non-Obligated Party with Separated RINs 

For a row of RINs in your RIN Holdings, select the Retire (Other) option in the "I want to..." drop-down, and 

click Go. Doing so will take you to the first step of the Retire Wizard (see Figure 37). 

Figure 37: Retire (Other) Wizard – Identify RINs (Step 1) 

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

completing. The following information is required to retire RINs for reasons other than compliance: 

● Renewable fuel code (D code); 

● Year the RINs being retired were generated; 

● Assignment of the RINs; 

● QAP service type code; 

● Number of RINs being retired; 

● Date the RINs were retired; and 

● Reason for the retire transaction. 

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

Type fields are automatically populated with the information from the row of RINs in the RIN Holdings grid 

RFS EMTS User’s Guide 28 
 

 

 

 

 

 

 

 

 

 

December 2017 

that you selected to retire. In the Reason for Retire field, only the reasons that are applicable to your 

organization's registered business activities are available (the remaining options are disabled). The Retire 

Wizard also contains a document grid you can use to specify the name and identifier of one or 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 screen, click Advanced RIN Selection at the bottom of the screen to 

navigate to the second screen of the Retire Wizard. On the Advanced RIN Selection screen, 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 screen, click Add to Transaction Bin at the bottom of the screen 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 screen 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 screen 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 screen. The following information is required to retire 

RINS for compliance: 

● Renewable fuel code (D code); 

● Year the RINs being retired were generated; 

● QAP service type code; 

● Number of RINs being retired; and 

● Date the RINs were retired. 

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

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

selected to retire. Additionally, the Assignment, Reason for Retire, Compliance Year, and Compliance Level 

are automatically hard-coded based on your selections from the RIN Holdings grid although Compliance Year 

is editable for Renewable Fuel Exporters (see Figure 38).

Trading RINs 

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

your RIN Holdings. The following information is required to initiate a trade through a sell transaction: 

● Renewable fuel code; 

● Year in which the RINs that were sold were generated; 

● Assignment of the RINs; 

● QAP service type code; 

● Number of RINs that were sold; 

● Volume of renewable fuel sold with the RINs (for assigned RINs only); 

● Identifier of the organization to which you are selling RINs; 

● Name of the organization to which you are selling RINs; 

● Date on which the trade occurred as recorded on the Product Transfer Document (PTD); 

● Price per RIN or the price per gallon of renewable fuel that was agreed upon by both parties (price 

must be rounded to two decimal places); and 

● Reason the RINs have been sold. 

For a row of RIN data in your RIN Holdings grid, select Sell in the "I want to..." drop-down, and click Go. Doing 

so will take you to the first screen of the Sell Wizard (see Figure 40). 

Figure 40: Sell RINs – Identify RINs Screen (Step 1) 

RFS EMTS User’s Guide 32 
 

 

 

 

 

 

 

 

December 2017 

The green boxes on the right side of the screen indicate which of the four steps of the Sell Wizard you are 

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

QAP Service Type fields are automatically populated with the information from the row of RINs in the RIN

Holdings grid that you selected to sell. Once you complete the information on this screen, click Select Trading 

Partner to move to the next screen. On the Select Trading Partner screen, you must identify a trading partner

from a list of organizations that satisfy the search criteria. You can search for an organization by Organization 

Name or Organization ID. In Figure 41, the organization names were filtered on the word "Better," and Better

Fuel Corporation was selected from the options. The trading partner organization must have an enabled 

business activity that allows it to buy RINs. 

Figure 41: Sell RINs – Select Trading Partner 

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

On the Sell RINs – Transaction Details and Documents screen, 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. Note that you may not enter both price per RIN and price per gallon. 

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 

RFS EMTS User’s Guide 33 
 

 

 

 

 

 

 

 

 

 

December 2017 

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 can also provide a Product Transfer Document (PTD) number, Bill of Lading, Invoice, and other 

additional information. The Transaction Details and Documents screen 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 screen, click Advanced RIN Selection to move to the final screen of the Sell Wizard. 

On the Advanced RIN Selection screen, 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 screen 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 screen 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 screen 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 

42). The RINs will remain in the Pending column until the trading partner accepts the sell transaction. 

Figure 42: Pending RINs in RIN Holdings Grid 

The following information is required to initiate a buy transaction: 

● Renewable fuel code; 

● Year in which the RINs that were bought were generated; 

● Assignment of the RINs; 

● QAP service type code; 

● Number of RINs that were bought; 

● Volume of renewable fuel bought with the RINs (for assigned RINs only); 

● Identifier of the organization that has sold the RINs; 

● Name of the organization that has sold the RINs; 

● Date on which the trade occurred as recorded on the PTD; 

● Price per RIN or the price per gallon of renewable fuel that was agreed upon by both parties. Price 

must be recorded to two decimal places; and 

● Reason the RINs have been bought. 

RFS EMTS User’s Guide 34 
 

 

 

 

 

December 2017 

To initiate a buy transaction, go to the Manage RIN Holdings screen, 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, Assignment, and

QAP Service Type in the Buy Wizard will be pre-populated with information from that row. 

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

fields marked with a red asterisk are required. On the Identify RINs screen, 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 43. 

Figure 43: Buy RINs – Identify RINs Screen (Step 1) 

RFS EMTS User’s Guide 35 
 

 

 

 

 

 

 

 

 

 

December 2017 

Once you click this tab, you will be able to access the Advanced Options fields (see Figure 44). 

Figure 44: Buy RINs – Advanced Options 

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 screen of the Buy Wizard, click Select Trading 

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

have the same behavior as the corresponding screens in the Sell Wizard. For buy transactions, the trading 

partner organization must have an enabled business activity that allows it to sell RINs. From the Transaction

Details and Documents screen, 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 screen is organization-specific (see tabs in

Figure 45), so to switch the organization for which the screen is displayed, open the Organizations tab of the 

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

RFS EMTS User’s Guide 36 
 

 

 

 

 

 

December 2017 

Figure 45: Review RFS2 Trades Screen 

The Review Trades screen 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 46, 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 43). If you choose 

RFS EMTS User’s Guide 37 
 

 

 

 

 

 

December 2017 

Cancel, you will be prompted 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 46: 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 47). 

Figure 47: 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 48). Once you click 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 prompted to provide

the price of the transaction (see Figure 49). 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

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. 

RFS EMTS User’s Guide 40 
 

 

 

 

 

 

 

 

December 2017 

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 Deny 

Trade screen (see Figure 48), and clicking Accept Trade will take you to the Accept Trade screen (see Figure 

49). 

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 screen. 

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 screen. 

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. QAP Service Type; and 

7. Transaction Date. 

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

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 

RFS EMTS User’s Guide 41 
 

 

 

 

 

 

 

 

December 2017 

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 or own RINs that were generated 

by a specific renewable fuel producer, importer, or 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, importer, or

facility on the buying organization's Blocked List, the transaction will automatically be denied by EMTS, and 

a notification will be sent to both parties indicating that the transaction was not processed. You can access 

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

Figure 50: View Blocked List Screen 

From the View Blocked List screen (see Figure 50), 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 opens 

the Add Producer to Blocked List screen (see Figure 51). On the Add Producer to Blocked List screen, 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 click Select. In Figure 48, the organization list 

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

Figure 52: 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. Note that you may select an organization on the View Blocked 

List screen regardless of whether that organization has produced RINS or has been enabled as a current

producer. 

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

View Details opens the View Blocked List Details screen 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 opens 

the Confirm Removal screen (see Figure 53). The screen displays all of the information included on the View

Details screen. You must click Confirm Remove at the bottom of the screen 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.

Converting Excel Files to XML 

EMTS includes functionality to convert an MS Excel file into a valid XML file. EPA provides a blank Excel

template, which allows users to include all transaction types in one file. It includes general notes about 

submitting transactions, user-specific submittal information, and a tab for each transaction type. 

The EMTS Excel Conversion Template is located on the EPA’s website here: 

http://www2.epa.gov/fuels-registration-reporting-and-compliance-help/template-converting-ms-excelfiles-xml-epa. 

Important Notes: The transaction types must remain in the same order presented in the template: 

Generate, Buy, Separate, Sell, Retire, Lock, and Unlock. The template header rows also must remain

unchanged to allow EMTS to process the file. 

Required columns have a header that is highlighted yellow. Additional information is included in column 

header comments and in the Notes tab. To view comments, hover over the header, as shown in Figure 57

Figure 58: EMTS Home Screen Submit File Options 

The Submit File screen is user-specific, so if you represent multiple organizations, you can submit files for 

all of your organizations from the Submit File screen without changing the organization that you represent.

However, submissions for each organization must be included in a separate file submission. From this 

screen, you may submit only one Excel file at a time. In addition, you may not submit multiple files with the 

same file name in a given calendar year (to prevent accidental duplication). 

On the Submit File screen (see Figure 59), click the Browse button to identify the Excel file you would like 

to convert. The tab order and name, as well as the header rows, must remain unchanged from the Excel 

Template. 

Figure 59: Submit File Screen 

Once you have identified a file, click the Convert button (see Figure 60). After clicking the Convert button, it 

may take some time to process, so please be patient.

Test_file.xls 

If your file was successfully converted from Excel to XML, you will see the following screen pop up (see 

Figure 61), which provides you with an opportunity to save the XML file for your records. If your file had 

any errors during conversion, you will see the corresponding QA Check Errors pop up on the Submit File

screen. Once you have corrected your errors, re-submit the file and click the Convert button.

Once you have saved the XML file for your records, you are ready to submit it for processing. Click the 

Submit button from the Submit File screen, as shown in Figure 62. It may take some time to process, so 

please be patient and avoid clicking the Submit button again. 

Figure 62: Submit Converted Excel File 

Test_file.xls 

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 screen. If your file is valid,

the message on the Submit File screen will be updated to indicate that your file has been submitted, as seen 

in the figure below. 

Figure 63: Submit File Screen 

To view the CDX node status details for your submission, click the View Submit File History button. You can 

also access the Submit File History screen by hovering over the Submissions menu option and clicking

Submit File History. The Submit File History screen (see Figure 64), like the Submit File screen, is userRFS EMTS User’s Guide 52

specific (not organization-specific), 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 screen 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.

Processing by EMTS 

After confirming that the file was successfully received by CDX, you will need to check whether the file was 

processed by EMTS. It is possible for your file to have been successfully received by CDX, but not 

successfully processed by EMTS. 

In order to confirm whether your transaction has been successfully processed by EMTS, hover over the

Submissions menu option and click View Node Submissions. The View Node Submissions screen displays 

the results of XML files submitted from a personal node or node client along with XML files submitted from 

the Submit File screen, which acts as a node client. 

RFS EMTS User’s Guide 53

In the example shown in Figure 65, the submission was successfully sent to CDX, but failed to be processed 

by EMTS, as seen in the results circled in the “Submission Status” column.

The View Node Submissions screen is organization-specific (and not user-specific), which means that the 

screen displays the status of all files submitted by representatives of the organization specified above the 

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 click Filter. 

This screen displays the date and time XML files were submitted, CDX and Submission IDs, the file names, 

and whether the files were successfully processed. 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 66).

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

submission. For processed and failed files, you can also download the submitted XML file the View Node 

Submissions screen. The submitted files are stored and available for download for a limited amount of time. 

From the View Node Submissions screen, 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. 

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, on the EMTS Documents screen. 

To receive these notifications, you must first subscribe to the notifications from the RFS2 Subscriptions

screen (see Figure 67) (click RFS2 Subscriptions under the Reports menu option). Users will be automatically 

subscribed to some notifications.

To subscribe to a notification, click Go in the "I want to..." column. On the Manage Subscription screen for 

that notification, check the “Subscribed” checkbox. For the immediate notifications, the frequency will be 

“Immediate,” and for the daily notifications, the frequency will be “Daily.” All notifications will be text format 

and will be delivered via email. All subscriptions are organization specific, so if one submitter for an 

organization subscribes to a notification, then all submitters for that organization will receive the

notification. 

Receiving Documents 

EMTS also creates various reports and documents that include information about data submitted for your 

organization. These documents can be accessed from the EMTS website (click View Reports under the

Reports menu item) or retrieved from the EMTS node. 

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 RFS2 Subscriptions screen (see Figure 68) (click RFS2 

Subscriptions under the Reports menu option). 

Note: If you subscribe to a document and then do not download the document within 22 business days, you 

will be automatically unsubscribed from that document. You will receive an email notification before and 

after the system performs this action. You may re-subscribe to the document at any time. 

On the RFS2 Subscriptions screen, click Go in the "I want to..." column to update the subscription for a specific 

document. On the Manage Subscription screen for that document, check the “Subscribed” checkbox to 

subscribe to the document. If the document is available at multiple frequencies (i.e. Daily and three-per-day), 

select the desired frequency. Documents can be received in CSV or XML format and can be downloaded from 

the EMTS website or from the EMTS node using a node or a node client. 

After you subscribe to a document, you will be able to download the documents with a daily subscription

frequency the following morning and the documents with a subscription frequency of three times per day at 

the next document generation interval. Three-per-day reports are generated at 1AM, 1PM, and 6PM. Weekly 

reports are generated Sunday mornings. You can download the documents from the View RFS2 Reports

screen (see Figure 68) (click View RFS2 Reports under the Reports menu option).

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. A recommended practice is to review your current RIN 

holdings periodically on the EMTS user interface, checking the total quantity of RINs against your own

transaction records. You may download data from this screen at any time. You can report transaction errors 

following the end of the quarter. 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. Note that you 

may edit your transaction errors and request the Transaction Error Report for the prior quarter any number

of times until the quarterly report submittal deadline, is two months after the quarter ends. Reports are due 

May 31, August 31, November 30, and February 28. 

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, click Continue. 

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

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

edit the errors on this screen. You can also enter multiple errors at a time by uploading a properly formatted

CSV file on the View Reported Errors screen. The file must only include errors for transactions that have not 

already been reported, transactions for the user’s organization, and from the current quarter.

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

and you will be able to add or edit transaction errors until the end of the quarterly 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 screen (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 click Go, you will see a

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://www2.epa.gov/fuels-registration-reporting-and-compliance-help/how-reportquarterly-and-annually-renewable-fuel. 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. 

RFS EMTS User’s Guide 71 
 

 

 

 

 

 

 

 

December 2017 

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 screen 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 screen 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 screen 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 79). 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.
