INFORMATION COLLECTION REQUEST (ICR)

Part A of the Supporting Statement

(Draft - March 2014) 

1. IDENTIFICATION OF THE INFORMATION COLLECTION

1(a) Title: Regulation of Fuels and Fuel Additives: Detergent Gasoline (Renewal)

EPA ICR No. 1655.09, OMB Control No. 2060-0275

1(b) Abstract

Gasoline combustion results in the formation of engine deposits. The accumulation of 

deposits, particularly in the orifices of fuel injectors and on intake valves, typically results in 

increased emissions and reduced engine performance. As fuel injectors replaced carburetors in 

the 1980's, a number of vehicle manufacturers experienced problems with deposit formation. 

Detergent additives, which had been available for years to control deposits in carbureted 

vehicles, were improved to accommodate the new technology. However, their use was voluntary

and there were no regulatory standards by which to gauge their effectiveness. Congress 

recognized the importance of effective detergent additives in minimizing vehicle emissions, and 

added Section 211(1) in the Clean Air Act Amendments of 1990. It required gasoline to contain 

detergent additives, effective January 1, 1995, and provided the Environmental Protection 

Agency (EPA) with the authority to establish specifications for such additives. The regulations 

at 40 CFR 80 - Subpart G implemented certification requirements for detergents and imposed a 

variety of recordkeeping and reporting requirements for certain parties involved with detergents, 

gasoline, or post-refinery component (any gasoline blending stock or any oxygenate that is 

blended with gasoline subsequent to the gasoline refining process (PRC)). All gasolines must 

contain certified detergents, with the exception of research, racing, and aviation gasolines.

The EPA maintains a list of certified gasoline detergents at 

http://www.epa.gov/otaq/additive.htm. As of March 2014 there were 374 certified detergents 

and 17 detergent manufacturers. Most of the certification activity occurred during the early 

years of the program. In 2012, 12 detergents were certified. In 2013, only 3 new detergents

were certified.

There are approximately 250 refiners and importers of gasoline, 1,350 blenders of 

detergent into gasoline or PRC, 8,000 carriers of gasoline or PRC, 200,000 gasoline retail 

outlets, and 100,000 fleet facilities which handle gasoline. The estimated total annual burden for 

respondents for this collection is 220,181 hours and $20,180,587, including $335,040 in 

annualized capital or O&M costs. The estimated total annual Agency burden is 200 hours and 

$16,400 in labor costs.

2. NEED FOR AND USE OF THE COLLECTION

2(a) Need/Authority for the Collection

Motor vehicles comprise the major source of air pollution in most urban areas, and 

account for about half of the toxic air emissions in the United States. Gasoline detergents help to 

minimize emissions. Detergents are typically added to gasoline as it is loaded into tank trucks at 

terminals. Section 211(l) of the Clean Air Act (Act) requires that all gasoline contain effective 

detergent additives. Section 114 of the Act provides EPA with the authority to impose 

recordkeeping and reporting requirements if necessary for enforcement of statutory

requirements. The recordkeeping and reporting requirements for this program, at 40 CFR 80 -

Subpart G, are necessary in order for EPA to certify detergents, to demonstrate that certified 

detergents are effective, to assure that gasoline contains certified detergents at the minimum 

concentration (also known as the lowest additive concentration (LAC)) necessary to be effective, 

and to deter violations. There is no standard test procedure for testing qualitatively and 

quantitatively for specific detergents in gasoline, thus necessitating reliance on recordkeeping 

and reporting as detergents, gasoline, and PRC pass through the distribution system. Blenders of 

detergent into gasoline or PRC are required to maintain records that demonstrate that the LAC is 

met, on average, each month at each automated blending facility, and by batch at non-automated 

facilities. These records are known as volumetric additive reconciliation (VAR) records. There 

is economic incentive to violate because uncertified detergents are typically less expensive, and 

blending a certified detergent at less than the minimum specified concentration will also save 

money. 

A detergent manufacturer has a variety of options under which it may certify a detergent. 

The primary option is “National Generic Certification,” which allows the detergent to be used in 

any gasoline. We estimate that over 99% of detergents have been certified under this option. 

Other options include limiting a detergent to a Petroleum Administrative Defense District 

(PADD Certification), a specific gasoline pool (Fuel-specific Certification), or California 

gasoline (CARB-based Certification), under California’s detergent certification rule. All the 

options may be found at 40 CFR 80.163.

2(b) Practical Utility/Users of the Data

The list of certified detergents is publicly available. The fuel, additive, and motor vehicle 

industries are well aware that gasoline must contain certified detergents. The list is monitored by

the additive manufacturers in order to maintain an awareness of competitors. Manufacturers and 

distributors of gasoline, and blenders of detergent into gasoline, monitor the list to ensure that 

gasoline contains certified detergents and that the documentation accompanying gasoline 

indicates such.

Most of the data submitted by the detergent manufacturers are confidential. Thus access 

is restricted to authorized EPA personnel and authorized contractors. Review of the data is 
3

necessary to determine if the detergent manufacturer has met the certification requirements for a 

specific detergent and can be certified by EPA. The documentation accompanying the detergent, 

with the LAC and any use restrictions, is used by the detergent blender to ensure proper 

additization. Product transfer documents (PTDs) are monitored by transferors and transferees to 

ensure that they are handling legal detergents and gasolines. VARs are necessary for detergent 

blenders to demonstrate that they have additized properly.

As mentioned above, there is not a method of analyzing gasoline for the proper level of a 

certified detergent. Thus, the records required by this rule, particularly the VAR and 

certification records, are essential in EPA’s monitoring for compliance.

3. NONDUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA

3(a) Nonduplication

The records required here are not available elsewhere. In many instances the records are 

already produced as a customary business practice.

3(b) Public Notice

In compliance with the Paperwork Reduction Act, EPA has solicited comments for a 60-

day period prior to submission of the ICR to OMB. Notice has been published in the Federal 

Register.

3(c) Consultations

EPA consulted with the following people regarding this collection:

May Thomas

Sr HSES Analyst

Afton Chemical Corporation

330 S. Fourth Street, 3rd Floor

Richmond, VA 23219

Certification by the detergent manufacturers, and the development of VAR and QA 

records by blenders of detergent into gasoline or PRC, account for the regulatory burden. The 

other burdens discussed above are minor or customary business practices upon which the 

regulations did not impose significant additional burdens. As this program has matured, nearly 

all of the applications for detergent certification now rely on previous vehicle testing. We 

estimate only one application annually is based on new testing.

Consultations with detergent manufacturers indicate that they have become quite familiar 

with submitting applications based on previous testing, with burden estimates ranging from one

to four hours for preparation and submittal of the application. For an application based on new 

testing, however, there have been broad ranges of estimates, from 16 hours to 2000 hours. We 

believe that, as with the previous ICR, a reasonable average continues to be 60 hours for a 

detergent certification.

Past consultations with detergent blenders that use automated blending equipment (the 

vast majority of blenders) also indicates a range of estimated VAR/QA burden, from about 30 to 

260 hours per year per facility. This is to be expected since there is a wide range in the size of 

these facilities and a wide range in the degree of sophistication utilized in implementing the 

VAR requirements and voluntary QA procedures. The estimate for a detergent blender that does 

not use automated equipment is 500 hours per year. A major reason for the difference in burden 

between automated and non-automated equipment is the VAR period, which may be up to 30 

days for automated equipment, but is by batch for non-automated equipment and calculated 

manually.

3(d) Effects of Less Frequent Collection

Certification of an additive is one-time, with the exception of an annual fuel-property 

report in the case of a fuel-specific certification. (As of March 2014, there were no fuel-specific 

certifications, and no indication that any would be forthcoming.) VAR records and PTDs are 

ongoing and necessary for enforcement. The generation and transfer of PTDs are customary

business practices. Researchers using gasoline without a certified detergent are required to 

submit a brief annual report on their activities. EPA believes that the annual reporting 

requirements are reasonable and that a less frequent collection would hamper enforcement. 

Thus, less frequent collection is not a practicable alternative.

3(e) General Guidelines

All Office of Management and Budget (OMB) guidelines are met.

3(f) Confidentiality

Most of the information reported to EPA is business confidential and is governed by the 
5

Freedom of Information Act regulations for EPA at 40 CFR 2.

3(g) Sensitive Questions

There is no sensitive information requested.

4(b) Information Requested

(i) Data Items

REPORTING REQUIREMENTS

Detergent Manufacturers

For each detergent, the detergent manufacturer (includes an importer or a party which is 
6

not the manufacturer but is requesting certification as a detergent for a product manufactured by 

another party) is required to: 

(1) submit a certification letter to EPA containing a variety of information concerning the 

certification testing and options for which certification is requested (80.161(b)(3), 

80.163(c)(1)(iii), 80.164(a)); 

(2) submit certification test data, and/or the acceptance criteria a supplier must meet for detergent 

reactant materials, upon EPA request (80.165, 80.162(b)(1)); 

(3) submit a detailed description of the detergent’s composition to EPA pursuant to the 

registration requirements for fuel additives at 40 CFR 79, addressing specific compositional 

descriptions identified in 40 CFR 80 and the LAC for each certification option 

(80.161(b)(1)(i),(ii),(ii)(A), 80.162); 

(4) ship a sample of the detergent and certain information concerning the sample to EPA, and if 

requested by EPA, ship an additional sample (80.161(b)(2), 80.167(d)); 

(5) notify EPA in writing, with supporting data, if there is a change in the LAC for which the 

additive is effective (80.161(b)(1)(ii)(C)); 

(6) notify, in writing, gasoline manufacturers (includes importers), detergent blenders, and all 

others who purchase the detergent, of the LAC and any use restrictions (80.161(c)); 

(7) submit certain information annually for each fuel-specific certification option (80.164(c)(3)); 

(8) notify customers if a fuel-specific certification is no longer valid (80.164(c)(3)(iii)); 

(9) if, upon receipt from EPA of a notice of intent of detergent disqualification, wishing to 

respond, submit written comments in an attempt to demonstrate compliance (80.161(e)(3), (4); 

and

(10) submit a list of customers to EPA if EPA should issue a final decision to disqualify a 

certified detergent (80.161(e)(6)).

Detergent Blenders

A blender of detergent into gasoline or PRC: 

(1) is required to notify EPA in writing if it intends to use a detergent at lower than its LAC, and, 

if requested by EPA, must submit the data supporting the use of the lower concentration 

(80.161(d)(1), (2), (3)); 
7

(2) who has certified under a fuel-specific option, is required to supply, upon request, EPA with 

a sample of the test fuel or with blendstocks with which to formulate the test fuel (80.167(d)); 

and

(3) is required to generate VAR records (80.170), and, upon request, to provide EPA with VAR 

records and supporting documentation (80.170(g)).

Transferors and Transferees

A transferor of gasoline, detergent, or PRC, including any gasoline refiner, importer, 

reseller, distributor, carrier, retailer, wholesale purchaser-consumer (WPC), oxygenate blender, 

detergent manufacturer, distributor, carrier, or blender, shall:

(1) generate or obtain documentation for each shipment and provide this documentation (product 

transfer document (PTD)) to the transferee (with exception of delivery of detergent-additized 

gasoline to motorists and small volumes to fleets) identifying the product, its detergent status if 

gasoline or PRC, and certain additional information (80.171); and 

(2) as a defense against liability, along with transferees, may establish quality assurance (QA) 

procedures that involve the development of records in addition to those required by the rules 

(80.169).

Researchers

A party conducting research on gasoline that does not contain a certified detergent is 

required to notify EPA annually, in writing (80.173(a)(3)).

Racing Gasoline/Aviation Gasoline

Parties handling racing gasoline or aviation gasoline are required to generate or transfer 

PTDs indicating that these products are limited to those uses (80.173(b)(1)). Pump stands for 

racing gasoline or aviation gasoline must be appropriately labeled if located at a facility that 

dispenses gasoline to motor vehicles (80.173(b)(2)).

RECORDKEEPING REQUIREMENTS

Most records are required to be kept for five years, with exceptions for certain small 

businesses and California gasoline (80.164(c)(4), 80.169(c)(8), 80.170(g), 80.171(d)). This 

retention period is necessary in order to provide EPA with adequate time for inspection, is 

consistent with the relevant civil statute of limitations, and is consistent with the retention period 

for PTDs under the reformulated gasoline/anti-dumping rules at 40 CFR 80 - Subpart D (except 

for retailers in anti-dumping areas). There is no regulatory burden because businesses retain 
8

such records as a customary business practice.

Detergent Manufacturers

For each detergent, the detergent manufacturer is required to maintain records for: 

(1) the acceptance criteria for suppliers of detergent reactive materials (80.162(b)(1)); 

(2) the test data for fuel parameters supporting a fuel-specific certification (80.164(c)(1)); 

(3) the fuel composition survey results, and documentation on test methods and statistical 

procedures, used to support a fuel-specific certification (80.164(c)(4)); 

(4) the certification test (80.165); and 

(5) in order to have an affirmative defense for a potential violation of the certification program

controls and prohibitions, the fourier transform infrared spectroscopy (FTIR) and related data for 

each detergent batch (80.169(c)(4)(i)(C),(D)).

Detergent Blenders

A blender of detergent into gasoline or PRC is required to maintain the VAR records on 

the use of the detergent (80.170). Gasoline or PRC additized in California is exempt, provided 

the records required by California are maintained (80.173(c)).

 

Transferors and Transferees

Transferors and transferees of gasoline, detergent, or PRC: 

(1) are required to maintain the PTDs for each shipment (80.171); and 

(2) as a defense against liability, may establish QA procedures that involve retaining records in 

addition to those required to be retained by the rules (80.169). 

Researchers

A party conducting research on gasoline that does not contain a certified detergent is 

required to maintain documentation demonstrating that the gasoline has been used only for 

research (80.173(a)(1)).

Racing Gasoline/Aviation Gasoline

Parties handling racing gasoline or aviation gasoline are required to maintain the PTDs 
9

for each shipment (80.173(b)(1)). 

(ii) Respondent Activities

The following are required:

(1) Read and comprehend the regulatory requirements.

(2) Train personnel to meet the requirements, employing new technology and procedures as 

necessary.

(3) Develop the information that is not already available.

(4) Gather and organize the information.

(5) Review the information and, if necessary, take corrective action such that it can be 

concluded that the regulatory requirements have been met.

(6) Report the information to EPA and/or retain the information in storage, as specified in the 

regulations.

5. THE INFORMATION COLLECTED–AGENCY ACTIVITIES, COLLECTION 

METHODOLOGY, AND INFORMATION MANAGEMENT

5(a) Agency Activities

The following are required:

(1) Develop a thorough understanding of the regulatory requirements.

(2) Develop the skills necessary to convey the requirements to the respondents and others 

such that it can be comprehended easily. 

(3) Respond to inquiries on the requirements.

(4) Provide access to the regulations and the list of certified detergents.

(5) Review the reported information.

(6) Contact the respondent when the information has not been submitted properly and discuss 

how the deficiency can be corrected.

(7) Store the information.

(8) Enter the information into the database.

(9) Upon concluding that all requirements have been met, issue a letter to the manufacturer 

indicating that the detergent has been certified, and update the list of certified detergents.

(10) Maintain rigorous security for the protection of confidential business information.

(11) Maintain computer hardware and software.

(12) Monitor compliance via on-site inspections.

5(b) Collection Methodology and Management

The EPA has not issued forms. The respondents may submit and store the information in 
10

the format of their choice, including electronically. Because most of the information reported to 

EPA is confidential, it is housed in an office with an advanced security system. The computers 

on which the data are handled have no linkage outside this office.

5(c) Small Entity Flexibility

The reporting requirements have been made as simple as practical in order to minimize 

the burden on all parties, large and small. For small businesses subject to this rule, the vast 

majority are merely transporters or retailers of gasoline. Their only burden is the transfer and 

storage of PTDs, which is a customary business practice. Transfers of small volumes of 

additized gasoline to WPCs and other ultimate consumers are exempt from the PTD 

requirements (80.171(c)).

5(d) Collection Schedule

Reporting only required on occasion.

6. ESTIMATING THE BURDEN AND THE COST OF THE COLLECTION

6(a) and (b) Estimating Respondent Burden and Costs

Estimating the burden is straightforward. Capital/start-up costs were incurred by industry

in 1995. Third party activity, the transmittal or storage of PTDs, is a customary business 

practice. Operating and maintenance (O&M) costs are in three categories. First, the on-road 

engine testing to demonstrate that the detergent meets the deposit-control standards is performed 

at contractor facilities. The cost of this testing is about $200,000. As discussed above, this 

testing is being performed for only one new certified detergent each year, with the other 

certifications based on previous testing. The second O&M cost is for copying and postage for the 

estimated three submissions annually for detergent certification and one submission annually for 

research notification. At an estimated $10 per submission, the annual cost is $40. The third 

O&M cost is for the storage of the VAR records at the 1300 automated detergent blending 

facilities and 50 non-automated detergent blending facilities. The estimated annual cost per 

facility is $100, for a total of $135,000. 

Thus, the total annual O&M cost is $200,000 + $40 + $135,000 = $335,040.

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

technical, and clerical. According to the Bureau of Labor Statistics, May 2011 National 

Industry-Specific Occupational Employment and Wage Estimates, mean wages were:

Wages

Managerial $67.44 per hour
11

Technical $65.56 per hour

Clerical $22.17 per hour

Doubling for company overhead and employing a 2% annual inflation factor to bring the 

rates up to date, and, for convenience, rounding up to the nearest dollar, gives the following rates 

that will be used in this ICR:

Total Employer Cost

Managerial $135 per hour

Technical $131 per hour

Clerical $ 44 per hour 

Worksheet 1: Detergent Manufacturer Submissions for Certification

Our review of the submissions indicates a fairly wide range of burden. Many 

submissions are minor changes to existing certified detergents and are able to rely on previously

submitted data. We estimate that they require about four hours to prepare. About one out of 10

undergoes the complete development cycle with estimates of 16 to 2000 hours of burden.

Thus, we continue to believe that the average burden per detergent is estimated at about 60

hours, with the hours and costs allocated as follows (we estimate three submissions annually (17

manufacturers) for the next three years):

Activity Management Technical Clerical

Read 2 hours/$270 4 hours/$524 1 hour/$44

GRAND

TOTAL 60 hours/$7299

Worksheet 2: VAR and QA by Detergent Blenders with Automated Equipment

As noted above, respondents indicated a fairly wide range of burden, from 30 to 260

hours per year per blending facility, for the 1300 facilities nationwide. The VAR period may be 

as long as 30 days, but can be shorter due to changes in detergents, maintenance downtime, etc. 

We believe that a reasonable average burden is 150 hours per year per facility, representing 15 

VAR periods, for a total of 1300 x 15 = 19,500 responses annually. Thus, the estimated hours 

and costs per VAR period are:

Activity Management Technical Clerical

Read 0.1 hour/$13.50 0.8 hour/$104.64 0.4 hour/$17.52

Train 0.1 hour/$13.50 0.8 hour/$104.64 0.4 hour/$17.52

TOTALS 0.6 hour/$81.00 4.8 hours/$628.04 4.6 hours/$192.04

GRAND

TOTAL 10 hours/$901.08

Worksheet 3: VAR and QA by Detergent Blenders with Non-automated Equipment

There appears to be little blending occurring with non-automated equipment. However, 

since it is done manually, and the VAR is done per batch, we estimate 500 hours per year for 

such blenders. It is estimated that a blender of this type will do about a thousand batches per 

year, or a burden of 0.5 hour per batch. Using the same labor mix as Worksheet 2 gives a per 
13

batch cost of $45.05. We estimate that there are 50 blenders in this category, for a total of 

50,000 responses annually.

Worksheet 4: Notification by Researchers

We estimate that we will receive one letter annually from researchers notifying us that a 

gasoline without a certified detergent will be used for research purposes. Assuming a 

management official spent one-half hour on each letter and a clerical person also spent one-half 

hour, gives a burden of one hour and $89.50 per letter.

6(c) Estimating Agency Burden and Cost

The Agency activities described in section 5(a) are handled by engineers and scientists at 

the GS-13 level ($82 per hour, including 160% overhead, as per OMB policy). It is estimated 

that 200 hours are spent annually, for a cost to the government of $16,400. The program is 

running smoothly and, as noted above, the number of requests for certification has decreased 

from the previous ICR. Lease, computer, and security costs are covered in the ICR for the Fuel 

and Fuel Additive Registration requirements at 40 CFR 79 (EPA ICR Number 309.11, OMB 

Control Number 2060-1050), with which this program is closely integrated. 

6(d) and (e) Estimating the Respondent Universe and Total Burden and Costs, and

Bottom Line Burden and Costs

The following worksheet is based on the above discussions.

TOTALS 69,504 220,181/$19,845,547

Thus, the net annual burden to industry is 220,181 hours (3.17 hours per response). 

Labor costs are $19,845,547, and O&M costs are $335,040, for a total cost of $20,180,587.

6(f) Reasons for Change in Burden

The previous clearance consisted of 220,181 hours (3.17 hours per response), labor costs 

of $18,500,528, and O&M costs of $335,040, for a total cost of $18,835,568. There is no 

increase of hours in the total estimated respondent burden compared with the ICR currently 

approved by OMB. The respondent universe and responses also remained the same in this 

collection. There was an increase in cost to the industry of $1,345,019 per year due to updated 

numbers used to calculate the industry burden and to account for inflation.

6(g) Burden Statements

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

is estimated to average 3.6 hours per response. 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
