SUPPORTING STATEMENT FOR THE

RENEWABLE FUELS STANDARD (RFS2) PROGRAM (RENEWAL)

A. JUSTIFICATION

1. Identification of the Information Collection

1(a) Title: Renewable Fuels Standard (RFS2) Program, EPA ICR No. 2380.02, OMB 

Control Number 2060-0637.

1(b) Short characterization:

Section 1501 of the Energy Policy Act of 2005 (the Act) describes the renewable fuel 

program, also known as the Renewable Fuel Standard (RFS) program or RFS 1. This provision 

was added to the Clean Air Act as Section 211(o), and required EPA to establish a program to 

ensure that U.S. gasoline contains specific volumes of renewable fuel for each calendar year 

2006 through 2012. The program started in 2006 and was covered by EPA ICR No. 2242.02, 

OMB Control Number 2060-0600 which is now discontinued due to the expansion of the RFS1 

program now referenced as RFS2 and covered under a different ICR and OMB number.

RFS1 was designed to significantly increase the volume of renewable fuels that blended 

into gasoline, starting with calendar year 2006 to 2.78 percent. 2.78 percent of the gasoline sold 

or dispensed to consumers for calendar year 2006 had to be renewable fuel. The RFS1 program 

did not address issues for 2007 and beyond. The Agency needed to determine and publish the 

applicable renewable fuel standard for each year, and also needed to specifically identify liable 

parties, lay out the compliance program including recordkeeping and reporting requirements, and 

delineate all elements of the credit trading program including how credits are generated, how 

they can be transferred, and how they can be used for compliance purposes. All these and many

other issues impacting the full RFS program were addressed in a subsequent Agency action and

were not discussed in the proposed rulemaking (NPRM).

Please refer to “Regulation of Fuels and Fuel Additives: Renewable Fuel Standard 

Program – Notice of Proposed Rulemaking” and “Regulation of Fuels and Fuel Additives: 

Renewable Fuel Standard Program – Final Rule” (both available in docket number EPA-HQOAR-2005-0161) for a detailed discussion of the RFS1 program.

The Energy Independence and Security Act of 2007 (EISA) further amended the Clean 

Air Act, section 211(o), and required new regulations for renewable fuels. The newer RFS 

program is referred to in this supporting statement as "RFS2." Under RFS2, the volume 

requirement and types of renewable fuels are expanded; non-road uses are included (RFS1 only 

affected motor vehicle fuel); there are additional types of waivers and special provisions for 

renewable fuel types; and EPA has implemented an EPA Moderated Transaction System (EMTS) 

for RINs. Additional parties will be required to register, keep records, and report. Please refer to 

the Final Rule (available in docket number EPA-HQ-OAR-2005-0161) for a detailed discussion 

of the RFS2 program. 
With the new requirements in the RFS program now RFS2, all supporting information 

and notices will be addressed under EPA ICR No. 2380.02, OMB Control Number 2060-0637. 

This supporting statement provides tables that break down reporting items by party (e.g. 

producer, importer, refiner, etc.) and the cost related to their reporting activity. For compliance 

purposes, under RFS2, volumes of renewable fuel are identified through the use of renewable 

identification numbers (RINs) that are initially generated by the producer of the renewable fuel. 

However, there are additional types of RINs and the volume of RINs traded is expected to be 

great.

 

2. Need For, and Use of, the Collection

2(a) Authority for the Collection

Sections 114 and 208 of the Clean Air Act (CAA), 42 U.S.C. §§ 7414 and 7542, authorize 

EPA to require recordkeeping and reporting regarding enforcement of the provisions of Title II of 

the CAA. 

2(b) Practical Utility/Uses of the Data

The recordkeeping and reporting requirements of this regulation will allow EPA to 

monitor compliance with the RFS program.

3. Non-duplication, Consultation, and other Collection Criteria

3(a) Non-duplication

Efforts have been made to eliminate duplication in this information collection. The 

information collected is considered CBI and unique to the closed DCFUEL database. EPA has 

provided instructions in PDF in which the parties submit data in the Unified Report Form (XLS) 

to the Agency’s Central Data Exchange (CDX). CDX also allows for updating and corrections to 

individual accounts. The data relates to individual fuel volume by facility and are not available 

from other sources.

3(b) Public Notice

EPA sought comment on reporting requirements via the Federal Register on November 20, 2012 

(77 FR 69620). EPA received no public comments.

3(c) Consultations

EPA has consulted with two parties, Mr. Tim Hogan of the American Fuel and 

Petrochemical Manufactures, who can be contacted on (202)-457-0480, and Mr. Bob Schafer of
The National Biodiesel Board (NBB), who can be reached on 202-737-8801. Mr. Schafer did not 

respond. Mr. Tim Hogan reviewed the ICR as it relates to the obligated parties and found that 

the tables were not clear. Changes were made for better analysis of party burden.

3(d) Effects of Less Frequent Data Collection

We have designed the reporting schedule to coincide with existing reporting deadlines 

applicable to many of the same parties under such programs as RFG (Reformulated Gasoline) 

and anti-dumping and diesel fuel. Less frequent collection of data would make it impossible to 

carry out the provisions of the CAA and EISA. 

3(e) General Guidelines

EPA requests an exception to the OMB guidelines that agencies may only require records 

to be maintained for no more than three years. Section 40 CFR 80.1454(l) requires record 

retention for five years from the date the records were created. Records related to RIN 

transactions are to be kept five years from the transaction date. Records can be kept either 

electronically or on paper. EPA needs to make sure regulated parties keep records long enough to 

be evaluated for compliance during this time period. Any information claimed as confidential 

will be treated in accordance with 40 CFR Part 2 and established Agency procedures. 

Information that is received without a claim of confidentiality may be made available to the 

public without further notice to the submitter under 40 CFR § 2.203.

3(f) Confidentiality

We inform respondents that they may assert claims of business confidentiality (CBI) for 

information they submit. Actual RINs should not be treated as confidential business information 

under RFS2, as they are necessary identifiers to accompany renewable fuels. Any information 

claimed as confidential will be treated in accordance with 40 CFR Part 2 and established Agency

procedures. Information that is received without a claim of confidentiality may be made 

available to the public without further notice to the submitter under 40 CFR § 2.203.

3(g) Sensitive Information

This information collection does not require submission of any sensitive information.

4. The Respondents and the Information Requested

4(a) Respondents with NAICS/ SIC Codes

The respondents to this information collection fall into the following general industry

categories: petroleum refineries (324110/2911), ethyl alcohol manufacturers (325193/2869), 
other basic organic chemical manufacturing (325110/2869), chemical and allied products 

merchant wholesalers (426990/5169), petroleum bulk stations and terminals (422710/5171), 

petroleum and petroleum products merchant wholesalers (422720/5172), and other fuel dealers 

(454319/5989). 

Using the terminology associated with the RFS2 Rule, we have assumed the following 

classes of party, which are covered by this supporting statement. 

 Producers of renewable fuels

 Importers

 Obligated Parties

 Parties who own RINs (including foreign RIN owners)

4(b) Information Requested

The respondents are subject to this collection to demonstrate compliance with the RFS 

Program. For this purpose, the respondents are required to report to EPA, via the Agency’s

Central Data Exchange (CDX), their fuel volumes identified through the use of renewable 

identification numbers (RINs). The respondents are involved in the initial generation of 

renewable fuel to be introduced in commerce. Additional requested information to be reported

come from producers and importers in the form of attest engagements reports and new pathway

petition submissions.

(i) Data Items

On request by EPA records must be made available; for electronic records, this includes

equipment or software needed to read the electronic records. If requested by EPA, electronic 

records shall be converted to paper documents. The types of records for retention under this 

collection are as follows:

Recordkeeping: Common Requirements for All Parties

 Product Transfer Documents (PTDs) for any Activity as a Transferor/Transferee of 

ownership of Renewable Fuel

 Copies of Reports Submitted to EPA records related to RIN Transactions

 List of RINS Owned, Purchased, Sold, or Retired

 Parties Involved in Each Transaction – Transferor, Transferee, and any Broker or Agent

 Transaction Date

 Additional Information Related to Details of the Transaction and its Terms

 Any Parties Other Than Renewable Producers and Obligated Parties

 Obligated Parties should retain PTDs associated with transactions

Recordkeeping: Renewable Producer/Importer Specifics –1

 Records Related to the Generation and Assignment of RINs by Facility
 Batch Volume, Batch No., RIN, Renewable Type, Production/Import Date, Lab Results, 

Additional info related to RIN Generation

biomass ethanol through the displacement of 90 percent or more of the fossil fuel

normally used in the production of ethanol

 The amount and type of feedstocks used in producing cellulosic biomass ethanol

 The equivalent amount of fossil fuel (based on reasonable estimates) associated with the 

use of off-site generated waste heat that is used in the production of ethanol at plants 

producing cellulosic biomass ethanol through the displacement of 90 percent or more of 

the fossil fuel normally used in the production of ethanol

 The plot plan and process flow diagram for plants producing cellulosic biomass and 

waste derived ethanol

 The independent third party verification required under 40 CFR § 80.1155 for producers 

cellulosic biomass ethanol and waste derived ethanol

Recordkeeping: Obligated Parties & Renewable Exporters

 Records Related to the Use of RINS (by Facility if Applicable) for Compliance

 Methods and Variables Used to Calculate the RVO

 List of RINs Used to Demonstrate Compliance

Additional Information Related to Details of RIN Use for compliance

(ii) Respondent Activities

All respondents must be registered in the DCFUEL application to obtain a valid company

number to sign up in CDX. In CDX parties will submit facility registration corrections and 

updates and report fuel volumes used for buying and selling RINS in the EMTS. The 

information submitted to EPA during a company’s initial registration defines its roles,

responsibilities and participation in the EMTS environment. Producers and importers are 

responsible for financing a yearly attest engagement or audit to verify their facilities. In this 

collection producers and importers may also submit new pathway petitions for EPA approval.

5. The Information Collected - Agency Activities, Collection Methodology, and 

Information Management

5(a) Agency Activities

 All reports and registrations will be reviewed by EPA for completeness and for potential 

violations.
 Potential violations will be referred to enforcement personnel.

 Registration numbers will be issued for new registrants.

 Contacting reporting parties if there is a problem with their submission.

5(b) Collection and Methodology and Management

EPA will to continue to receive all reports, registrations, initial registrations and updates. We anticipate receiving data in a simplified and secure fashion via the Agency's electronic Central Data 

Exchange (CDX). Information claimed as CBI will be stored in appropriately controlled areas.

EPA will provide Guidance Documents, Report Instructions and Report Templates on 

http://www.epa.gov/otaq/regs/fuels/forms.htm.

5(c) Small Entity Flexibility Provisions 

The flexibility provisions that are available to small entities are found in 40 CFR § 

80.1441 and § 80.1442. These refiners have less than 1,500 employees corporate-wide and corporate average crude oil capacity less than or equal to 155,000 barrels per calendar day. There 

are only six refiners that meet this definition registered in DCFUEL under the RFS2 program. 

The following provisions were finalized in the RFS2 final rule to assist small entities that could 

benefit from some additional flexibility in compliance with the RFS program: 

 Case-by-Case Hardship for Small Refiners (and Small Refineries). Small refineries 

and small refiners may also apply for an extension of the temporary exemption, based 

upon disproportionate economic hardship, on a case-by-case basis. Any small refinery or 

small refiner may apply for this case-by-case hardship at any time. In evaluating applications for this hardship provision, EPA will take into consideration information such as: 

information gathered from annual reports, RIN system progress updates, information 

provided by the petitioner, and information gathered through consultation with the Department of Energy (DOE). If granted an exemption, the refinery would also be exempt 

from all recordkeeping and reporting requirements.

 Small volume production facilities and importers exemption. Permanently exempt 

(production/importation of less than 10,000 gallons annually) or temporarily exempt 

(production of less than 125,000 annually) are exempt from: generating RINS, registration, reporting, recordkeeping, and attest engagement requirements. The exemption only

applies as long as a small volume production facility or importer does not own RINs or 

voluntarily generate and assign RINs. 

5(d) Collection Schedule

Registrations are received on a rolling basis. Updates may be sent in at any time after 

initial registration. New parties may enter the regulated industry at any time, triggering 

registration requirements. Petitions for new renewable fuels and pathways are also being 

received.
6. Estimating the Burden and Cost of Collection

6(a) Estimating the Respondent Burden

We drew upon experience implementing similar regulations among the same entities to 

develop estimates of the burden associated with this collection. The number of each 

participating party was a result of registrations in the RFS2 program DCFUEL database. The

time per response assumptions or the time it takes to perform updates and corrections, new party 

registrations and new CDX registrations came from EPA’s experience implementing the RFS 

program and having knowledge from industry on how long it takes to produce compliance 

documents and entry of data in the Central Data Exchange (CDX) and EPA Moderated 

Transaction System (EMTS). EPA estimated that it would take industry 8 hours to produce a new 

pathways petition, twenty-four hours to perform a yearly attest engagement and 2 hours for new 

CDX and new party registrations. For existing members of any party, EPA has estimated 2 hours 

for registration updates and corrections. EPA has provided percentages by party totals to project

assumptions in this collection. The information used came from observed registration and 

reporting activity in CDX and EMTS. In this collection, producers and importers are required to 

finance and to submit to EPA a yearly attest engagement calculated at $206 per hour. In the last 

information request, respondents were required to re-register their companies which increased 

the cost and hourly burden. In this collection EPA should see a decrease in cost and responses.

From the estimates there are 1,672 participants in this collection.

 Producers of renewable fuels (500)

 Importers (72)

 Obligated Parties (150)

 Parties who own RINs (including foreign RIN owners) (950)

6(b) Estimating the Respondent Costs

Three labor categories are involved: managerial (includes legal and professional review), 

technical, and clerical. The estimates used the Bureau of Labor Statistics figures from "National 

Industry-Specific Occupational Employment & Wage Estimate “Petroleum and Coal Products 

Manufacturing” (May 2011), with a 3% annual inflation factor applied to bring the values to the 

present. Using this method, the following wages and benefits apply by category:

Wages and Benefits

Managerial $67.44 per hour

Technical $65.56 per hour

Clerical $22.17 per hour
Doubling for company overhead beyond wages and benefits, and for convenience, rounding up 

to the dollar, gives the following rates for this ICR:

Total Employer Cost

Managerial $135.00 per hour

Technical $131.00 per hour

Clerical $ 44.00 per hour

It is assumed that for each hour of activity the mix will be about 0.1 hour managerial, 0.7 hour 

technical, and 0.2 hour clerical. This gives an average labor cost of $103 per hour, which will be 

used in this ICR. For purchased services related to the yearly attest engagements for producers 

and importers, we have doubled this hourly cost to $206 in order to more accurately reflect the 

cost performing this service. There is no capitol or O&M cost associated with this collection. 

There is only respondent hourly burden cost incurred.

(c) Estimating the Agency Burden and Cost 

EPA must generate company and facility registration number(s) for new registrants and 

notify them of these numbers, which must appear on reports. Report formats and 

instructions/guidance must be prepared by Agency personnel. Reports will be processed by 

contractors and must be reviewed by Agency personnel. Reporting parties must be contacted if 

there is a problem with their submission. We have developed forms for RFS2 reporting to 

include four types, rather than one type, of RIN unlike the RFS1 templates. We have provided 

RFS2 reporting templates as an attachment to this document.

This supporting statement considers all Agency costs associated with accepting new 

registrants and new reports associated with RFS2, as expressed in EPA ICR Number 2333.02.

Using the RFS1, and the RFG and anti-dumping ICR, and other recent fuels-related ICRs as a 

guide in developing these initial estimates for RFS, we anticipate that RFS2 may require the 

equivalent labor of one full time GS-13 technical employees for a total of $115,000, and labor 

costs of $54,875 in the clerical category and $19,438 in the management category.

1

 Since we are 

using the CDX, some costs incurred by the Agency will be tied to the number of registrants who 

send us reports. Specifically, there is an annual "subscription cost" associated with the use of 

CDX that is passed on to the EPA program office and we estimate that registrants due to RFS2 

will cost our office approximately $200,000 per year in 2013, 2015 and 2015. We anticipate 

$266,666 in annual contract costs related to registration and reporting activities. We anticipate 

IT development and testing costs at $ 600,000 divided by three years to yield an annual cost of 

$200,000. Adding the following values results in an annual estimated Agency burden as follows:

One GS-13 technical employee (full time) = $ 115,000

One GS-7 clerical worker (full-time) = 54,875

One GS-15 manager (1/8 time) = 19,438

Annual CDX subscription fee = 200,000

Annual contract costs = 266,666

Testing and development= 200,000

TOTAL = $855,979

 As with all items in this supporting statement, we strongly encourage comment on the 

estimated Agency burden and on the Agency activities associated with this proposed information 

collection. 

 

(d) Estimating the Respondent Universe

 

1 These estimates are derived from "OPM Salary Table 2012-DCB," effective January 2012. This table may be 

found at http://www.opm.gov/oca/06tables/indexGS.asp. The extreme of step 10 was assumed for all categories. 

We have assumed a full-time GS-7 clerical worker, one full-time GS-13 technical worker, and a GS-15 manager 

working one-eighth of his/her time managing this project (0.125). All values were multiplied by 1.6 (which is a 

common factor utilized in ICRs to account for overhead costs). We rounded the resulting dollar value to the nearest 

thousand. This cost is per year.
We were able to estimate the number of regulated entities drawing upon experience 

regulating the same or similar entities. 

(e) Bottom Line Burden Hours and Costs

From the tables, we estimate the following annual totals:

TOTAL NO. OF RESPONDENTS: 1, 672

TOTAL NO. OF RESPONSES: 1,192

TOTAL BURDEN HOURS: 15,518

TOTAL COST TO RESPONDENTS: $ 3,019,754

(f) Reason for Change in Burden

There is a sharp decrease of 43,215 hours in the total estimated respondent burden 

compared to the ICR currently approved by OMB. The total burden hours will decrease from 

58,733 to 15,518 and the total number of responses from 7,396 to 1,192, both notable drops. 

This decrease was caused by members in the obligated parties once registered not being required 

to re-register their companies in this renewal. New registrations are required if a company

aquires another or when a new company enters into a party. The requirements of the current 

members in the obligated party are to submit updates and corrections to their current registration 

when needed in CDX. The number in the respondent universe will decreased in all categories for 

the obligated parties thus lessoning the reporting burden for its members.

6(g) Burden Statement

The annual public reporting and recordkeeping burden for this collection of information 

is estimated to be 13 hours per response (total number of hours divided by total number of 

responses). Burden means the total time, effort, or financial resources expended by persons to 

generate, maintain, retain, or disclose or provide information to or for a Federal agency. This 

includes the time needed to review instructions; develop, acquire, install, and utilize technology

and systems for the purposes of collecting, validating, and verifying information, processing and 

maintaining information, and disclosing and providing information; adjust the existing ways to 

comply with any previously applicable instructions and requirements; train personnel to be able 

to respond to a collection of information; search data sources; complete and review the collection 

of information; and transmit or otherwise disclose the information. An agency may not conduct 

or sponsor, and a person is not required to respond to, a collection of information unless it 

displays a currently valid OMB control number. The OMB control numbers for EPA's 

regulations are listed in 40 CFR part 9 and 48 CFR chapter 15. 

To comment on the Agency's need for this information, the accuracy of the provided 

burden estimates, and any suggested methods for minimizing respondent burden, including the 

use of automated collection techniques, EPA has established a public docket for this ICR under 

Docket ID number EPA-HQ-OAR-2005-0161, which is available for online viewing at 

www.regulations.gov,or in person viewing at the Air Docket in the EPA Docket Center in 
Washington, DC (EPA/DC). The docket is located in the EPA West Building, 1301 Constitution 

Avenue, NW, Room 3334, and is open from 8:30 a.m. to 4:30 p.m., Eastern Standard Time,
