  SEQ CHAPTER \h \r 1 INFORMATION COLLECTION REQUEST (ICR)

Part A of the Supporting Statement

		            

1.	IDENTIFICATION OF THE INFORMATION COLLECTION

	1(a)	Title:	Registration of Fuels and Fuel Additives: Health-Effects

			Research Requirements for Manufacturers (40 CFR part 79, subpart F)

			EPA ICR Number 1696.06, OMB Control Number 2060-0297

	1(b)	Abstract

	In accordance with the regulations at 40 CFR part 79, subparts A, B, C,
D and F (there is no Subpart E), Registration of Fuels and Fuel
Additives, manufacturers of (1) motor vehicle gasoline, (2) motor
vehicle diesel fuel, and (3) additives for those fuels, are required to
have their products registered by the Environmental Protection Agency
(EPA) prior to their introduction into commerce.  Registration involves
providing (1) a chemical description of the fuel or additive, (2)
certain technical and marketing information, and (3) certain
health-effects information.  Periodic reports on production and related
information are required.  Subpart F requires the conduct of
health-effects research.  This ICR addresses the information collection
requirements of that research.  The information collection requirements
of Subparts A through D, and the supplemental notification requirement
of Subpart F (indicating how the manufacturer plans to satisfy the
research requirements, or qualifies for an exemption) are covered by a
separate ICR (OMB Control Number 2060-0150).  

	The program is operated by the Transportation and Regional Programs
Division, Office of Transportation and Air Quality, Office of Air and
Radiation.  The information developed by the health-effects research
will be used to identify products whose evaporative or exhaust emissions
pose a particular threat to public health, thus meriting further
investigation and/or regulation.  Manufacturers of similar products are
allowed to group in order to share the research costs.  Several groups,
also known as consortiums, have been formed.  The largest consortium,
organized by the American Petroleum Institute (API), represents most of
the manufacturers of conventional gasolines, diesel fuels, and
additives.  The regulations define the fuel/additive categories for
which the research is required.  There are three tiers of requirements. 
Tier 1 requires an emissions characterization (combustion, and in
certain instances, evaporative) and a literature search over the past 30
years for health-effects information on those emissions.  Tier 2 (also
known as standard Tier 2) requires short-term inhalation exposures of
laboratory animals to emissions (combustion, and if required under Tier
1, evaporative) to screen for adverse health effects.  The EPA has the
authority to require “Alternative Tier 2" testing if there is a
reasonable basis to conclude that such testing is more appropriate.  The
EPA reached that conclusion with respect to gasoline and
gasoline-oxygenate blends.  The API consortium was notified of the
proposed alternative requirements in 1997.  After public review and
comment, and discussions with API, the alternative requirements were
finalized and API notified in 1998.  Similar situations existed for a
manganese gasoline additive known a MMT, manufactured by the Ethyl
Corporation (now Afton Chemical Corporation), and a blend of diesel fuel
and water, known as PuriNOx, manufactured by the Lubrizol Corporation. 
Tier 3 provides for follow-up research.  Tier 3 can be required when
uncertainties as to the significance of observed health effects, welfare
effects, and/or emissions exposures from a fuel or fuel/additive mixture
interfere with EPA’s ability to make reasonable estimates of the
potential risks posed by the emissions from such products. 

 

	There are approximately 500 fuel manufacturers, 1,000 additive
manufacturers, 700 registered fuels, and 6,700 registered additives. 
These numbers change daily.

2.	NEED FOR AND USE OF THE COLLECTION

	2(a)	Need/Authority for the Collection

	Motor vehicles comprise a major source of air pollution in urban areas,
and account for about half the toxic air emissions in the United States.
 Congress demonstrated its strong concern for the protection of public
health by providing broad legislative authority to monitor and regulate
fuels, fuel additives, and their emissions.  This registration program
was established by the Air Quality Act of 1967, carried forward into the
Clean Air Act (Act) of 1970, and strengthened in the Act’s 1977 and
1990 reauthorizations.

	Section 211(a) of the Act provides EPA with the authority to designate,
by regulation, any mobile source fuel or additive for registration.  Any
fuel or additive used to such an extent that there is, or would be,
significant public emissions exposure, is an appropriate candidate. 
Once designated, it may not be introduced into commerce until it has
been registered by EPA.  Section 211(b) requires, for the purpose of
registration, that the manufacturer provide certain compositional and
related information.  It provides EPA with the authority to require
health-effects testing and the submittal of health-effects data and
related data.  Section 211(e), a 1977 amendment, made the health-effects
research requirements mandatory.  The original regulations were
promulgated by the Department of Health, Education, and Welfare in 1970
and transferred to the EPA shortly thereafter.  They ultimately resided
at 40 CFR 79 and were revised in 1975, 1976, 1978, 1994, 1996, 1997 and
1998.  Due to their broad public emissions exposure, motor vehicle
gasoline and diesel fuel, and their additives, were designated.

	The regulations at 40 CFR part 79, subpart F, promulgated on May 27,
1994, require research for each of the following fuel/additive groups
whose components are derived from conventional petroleum, heavy oil
deposits, coal, tar sands and/or oil sands:

	(1) Gasoline

Baseline Group - gasoline/additive elements are limited to carbon,
hydrogen, oxygen, nitrogen and sulfur (for convenience, hereby referred
to as CHONS), gasoline oxygen content is less than 1.5 weight percent,
and the gasoline meets the American Society for Testing and Materials
(ASTM) specifications.

Nonbaseline Group - gasoline/additive elements are limited to CHONS,
gasoline oxygen content is 1.5 weight percent or greater, and the
gasoline meets ASTM specifications.  A group is established for each
oxygenate (e.g., ethanol).

Atypical Group - a group is established for each non-CHONS element
(e.g., manganese), combination of non-CHONS elements, property that does
not meet ASTM specification, or combination of properties that do not
meet ASTM specifications.  

	(2) Diesel

Baseline Group - diesel/additive elements are limited to CHONS, the fuel
oxygen content is less than 1.0 weight percent, and the fuel meets ASTM
specifications. 

Nonbaseline Group - diesel/additive elements are limited to CHONS, the
fuel oxygen content is 1.0 weight percent or greater, and the fuel meets
ASTM specifications.  A group is established for each oxygenate.  An
exception is biodiesel, which is one group, even though it consists of
mixed alkyl esters of plant and/or animal origin. 

Atypical Group - a group is established for each non-CHONS element
(e.g., iron), combination of non-CHONS elements, property that does not
meet ASTM specification, or combination of properties that do not meet
ASTM specifications.

	

	The regulations also require research for each gasoline, diesel fuel,
and additive group that is derived in whole or in part from sources
other than those mentioned above, such as shale, used oil, and waste
plastics.  The fuel/additive group is defined by the source.  Research
is also required for fuels that do not meet ASTM specifications.

	The research is structured into three tiers of requirements for each
group.  Tier 1 requires an emissions characterization and a literature
search for the health effects of those emissions.  For products
registered as of May 27, 1994, the Tier 1 data were due by May 27, 1997.
 For products currently seeking registration, the Tier 1 data must be
submitted before the product can be registered.  Tier 2 requires
short-term inhalation exposures of laboratory animals to emissions to
screen for adverse health effects.  For products registered as of May
27, 1994, the Tier 2 data were due by May 27, 1997, or evidence of a
contract that would provide the Tier 2 data by May 27, 2000.  For
products currently seeking registration, the Tier 2 data are due before
registration can occur.   (There are several exceptions to the above. 
For biodiesel products, the Tier 1 deadline was March 17, 1998, and the
Tier 2 deadline was May 27, 2000.  For atypical products, the Tier 2
deadline for evidence of a contract was November 27, 1998, with the Tier
2 data due by November 27, 2001.)   The regulations also allow EPA to
establish Alternative Tier 2 requirements in lieu of standard Tier 2, if
warranted.  Follow-up studies, if required, would occur under Tier 3.  

	The objective of the program is to determine if there are any fuels
and/or additives whose evaporative emissions or products of combustion
pose a particular danger to public health or welfare.  Section 211(c) of
the Act provides EPA with the authority to regulate such fuels and
additives.  For example, the use of lead additives in gasoline, gasoline
volatility, and the sulfur content of gasoline and diesel fuel, have
been regulated under this section.  

	There are several exceptions to the above, in order to lessen the
burden for small businesses.  Manufacturers of baseline and/or
nonbaseline products, who have an annual sales revenue of less than $50
million, are exempt from Tier 1 and Tier 2.  Manufacturers of atypical
products, who have an annual sales revenue of less than $10 million, are
exempt from Tier 2.  There are less burdensome provisions for the
manufacturers of aerosol additives.  Manufacturers who merely re-label a
registered product are not subject to Tier 1, Tier 2 and Tier 3.

	In 1994 the API formed a consortium of the major fuel and additive
manufacturers.  In 1997 it submitted Tier 1 data for baseline gasoline,
baseline diesel, and six nonbaseline gasoline groups (di-isopropyl ether
(DIPE), ethanol, ethyl tertiary butyl ether (ETBE), methyl tertiary
butyl ether (MTBE), tertiary amyl methyl ether (TAME), and tertiary
butyl alcohol (TBA)).  Tier 2 data were submitted for baseline diesel.  
In 1997 a consortium submitted information for aerosol additive
manufacturers.  In 1997 Tier 1 data were submitted for two atypical
gasoline groups and five atypical diesel groups.  In 1998 and 2000, Tier
1 and Tier 2 data were submitted for biodiesel, respectively.  In 2000
and 2002, Tier 1 and Tier 2 data were submitted for summer PuriNOx, an
emulsion of water and diesel.  In 2003 Tier 1 data were submitted for
Clean Fuels Technology Emulsified Diesel Fuel.  In 2005 Tier 1 data were
submitted for an iron-based diesel additive known as CleanBoost.  In
2006 Tier 1 data were submitted for the cerium-based diesel additive
Envirox, a mixture of ethanol and diesel fuel known as O2Diesel, and the
diesel additive Green Plus 850.  In 2007 Tier 1 data were submitted for
Renewable Diesel Mixtures, Green Plus 851, and a mixture of ethanol,
diesel and biodiesel.  In 2008 Tier 1 data were submitted for NExBTL
Renewable Diesel and Nextfuels, Inc. biodiesel.  In 2009 Tier 1 data
were submitted for two renewable diesels.

	On August 20, 1997 the API was informed of proposed Alternative Tier 2
requirements for baseline gasoline and the six nonbaseline gasoline
groups for which Tier 1 data were submitted.  After public notice and
comment, and discussions with API, the alternative requirements were
finalized, and API was notified on November 2, 1998.  Notice was
published in the Federal Register.  The research is nearing completion. 
  

	In 1994 the Ethyl Corporation (Ethyl) was informed that Alternative
Tier 2 testing would be required for its manganese additive MMT and
alternative requirements were proposed in a January 25, 1999 letter to
Ethyl and announced in the Federal Register.  These requirements were
finalized in a May 11, 2000 letter to Ethyl and announced in the Federal
Register.  The research has been completed.

	Alternative Tier 2 requirements were also established for winter
PuriNOx.  The procedure as described above was followed and the data
were submitted in 2003. 

	2(b)	Practical Utility/Users of the Data

	These health-effects data will allow decision makers to assess the
relative risks of the fuel/additive groups described above.  Should
areas of concern be identified for certain products, further regulatory
action could be taken.   

	The data may also be used by non-EPA organizations, such as
fuel/additive producers and trade organizations, to review a product’s
potential toxicity, exposure, or registration status, to determine
whether the submittal of further information would be duplicative, or to
contact producers to use the registration already granted and share in
the cost of previous compliance.  Public interest and environmental
organizations may review the data and perform their own evaluations. 
Laboratories may review the test reports for guidance on sound
laboratory practices and data generation.  Academic and medical experts
may use the information in research or to compare with independent
findings.  State and local agencies responsible for protecting the
public health may find these data to be of interest.  The California
Environmental Protection Agency assessed the use of oxygenates in
gasoline, not only from an emissions standpoint, but also from a
groundwater contamination standpoint, due to leaking storage tanks.

3.	NONDUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA

	3(a)	Non-duplication

	To our knowledge, this is the only program which requires the
manufacturers of motor vehicle fuels and fuel additives to develop
emissions health-effects data.  The regulations allow manufacturers of
similar products to group and test one representative of the group, thus
minimizing duplicative testing.

	

	3(b)	Public Notice

	A Federal Register notice requesting public comment on this ICR was
published on September 9, 2009 (74 FR 46422).  No comments were
received.  

	

	3(c)	Consultations

	Burden estimates were discussed in general with less than 10 parties.

	3(d)	Effects of Less Frequent Collection

	These are one-time requirements for each product.

	3(e)	General Guidelines

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

	3(f)	Confidentiality

	  Section 211(b)(2)(B) of the Act requires that the results of the Tier
2 health-effects testing shall not be considered confidential.  Some
Tier 1 data, particularly those related to composition, could be claimed
as confidential and would be subject to EPA’s freedom of information
provisions at 40 CFR 2.

	3(g)	Sensitive Questions

	There are no sensitive questions.

4.	THE RESPONDENTS AND THE INFORMATION COLLECTED

	4(b)	Information Requested

	(i)	Data Items

	The following is required to be submitted for each fuel and additive
subject to the Tier 1 requirements (40 CFR 79.52):

1. 	Name of the manufacturer and name of the fuel or additive;

2. 	Group/consortium identification;

3. 	Literature search over the past 30 years for existing information
pertaining to health 	effects, environmental effects, and emissions of
the fuel or additive; includes description 	of data bases searched,
search period, and summary of relevant information found, 	including
abstracts and references;

4.	Chemical characterization of combustion and evaporative emission
products; report on 	emissions generation procedures, analytic methods,
and results.  This requirement can be 	mitigated by adequate existing
information obtained during the literature search in item 3.  	The full
report(s) summarized in item 3 would be required.

	

	The following is required to be submitted for each fuel and additive
subject to the Tier 2 or  Alternative Tier 2  requirements (40 CFR
79.53):

1.	Name of the manufacturer and name of the fuel or additive;

2.	Group/consortium identification;

3.	Results of subchronic, 90-day, inhalation exposure of lab animals to
combustion emissions, and in separate testing, if applicable, to
evaporative emissions, for screening of general toxicity,
carcinogenicity, mutagenicity, adult reproduction/teratogenicity,
pulmonary toxicity, and neurotoxicity for Tier 2, or related negotiated
testing for Alternative Tier 2.  This requirement can be mitigated by
adequate existing information obtained during the literature search of
Tier 1.  The full report(s) summarized in Tier 1 would be required.

	The following is required to be submitted for each fuel and additive
subject to the Tier 3 requirements (40 CFR 79.54):

1. 	Name of the manufacturer and name of the fuel or additive;

2.	Group/consortium identification;

3.	Results of follow-up testing to resolve uncertainties identified upon
analysis of Tier 1 and/or Tier 2/Alternative Tier 2 data.  The test
requirements will be established through notice and comment and
negotiation with the manufacturer(s).  The burden will likely be
comparable to that for Tier 2 testing.

	See 40 CFR 79.59(c) for the detailed documentation requirements of the
Tier 1, Tier 2, and Alternative Tier 2 reports.  See 40 CFR 79.59(d) for
the detailed documentation requirements for a Tier 3 report.  There are
no recordkeeping requirements.

	(ii)	Respondent Activities

	The following activities are required:

1.	Read or hear the regulations at 40 CFR 79, Subpart F;

2.	Obtain the required data;

3.	Review the data;

4.	Prepare the required report(s);

5.	Send the report(s) to EPA.

5.	THE INFORMATION COLLECTED--AGENCY ACTIVITIES, COLLECTION 
METHODOLOGY, AND INFORMATION MANAGEMENT

	5(a)	Agency Activities

	The following activities are required:

1.	Respond to inquiries on the Tier 1, Tier 2, Alternative Tier 2, and
Tier 3 requirements;

2.	Provide copies of the regulations;

3.	Review the Tier 1, Tier 2, Alternative Tier 2, and Tier 3 reports;

4.	Upon completion of a review, notify the submitter that the report is
adequate, or, if it is 	inadequate, notify the submitter of the
deficiencies;

5.	Establish public access to the test results, as required by the Act,
while maintaining the 	confidentiality of data so entitled;

6.	Store the reports.

	

	5(b)	Collection Methodology and Management

	The reports will be reviewed by the Office of Transportation and Air
Quality and the Office of Research and Development.  The quality of the
data will be determined by professionals knowledgeable with emissions
and health-effects testing.  The review will be manual.  The nature of
the reports makes them unsuitable for automatic data processing.  The
reports will be available to the public in hard copy, and, if so
submitted, electronically.  They will be stored in the format submitted.

	

5(c)	Small Entity Flexibility

	As discussed in section 2(a), certain small businesses are exempt from
some or all of these requirements.

	5(d)	Collection Schedule

	There is no schedule.  The requirements apply when a manufacturer
applies for registration.

6.	ESTIMATING THE BURDEN AND THE COST OF THE COLLECTION

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

	Due to the costs, it is likely that only limited additional Tier 1
research will be done.  Future fuels and additives subject to Tier 1
will almost exclusively be those that can group with existing Tier 1
data, and likely will come from manufacturers who have already paid for
the Tier 1 data.  Thus, it is estimated that there will only be one Tier
1 submission per year over the next three years.  However, manufacturers
of baseline and nonbaseline products with less than $50 million in
annual revenue are exempt from Tier 1, so there will be continuing
registration activity in that area.

	In the previous ICR, it was concluded that the few new products for
which a new Tier 1 would be required are likely to be in the atypical or
nonbaseline categories, with an estimated Tier 1 cost of about $350,000
per product, with about $100,000 for the literature search and about
$250,000 for the emissions characterization.  Estimates from three
recent submitters were about $200,000, $775,000, and $2 million.  Thus,
we believe that a new estimate of about $437,000 is now appropriate.  

	The $437,000 estimate was determined as follows:

	In discussions with fewer than ten fuel and fuel additive
manufacturers, four labor categories were identified as having
involvement: managerial, legal, professional/technical (prof/tech), and
clerical.  According to the Bureau of Labor Statistics, May 2008
National Industry-Specific Occupational Employment and Wage Estimates,
mean wages were:

Managerial      $60.42 per hour

Legal		$84.56 per hour

Prof/Tech	$60.05 per hour

Clerical	$17.34 per hour

	Doubling for company overhead beyond and employing a 2% annual
inflation factor to bring the rates to 2009, and, for convenience,
rounding up to the even dollar, gives the following rates that will be
used in this ICR:

Total Employer Cost

Managerial 	$124 per hour

Legal		$174 per hour

Prof/Tech	$124 per hour

Clerical 	$  36 per hour

	This is a broader cost-per-hour range that in previous estimates for
this ICR.  We believe that the previous hourly burden estimate is still
representative, on average.

Worksheet 1: Tier 1 Literature Search

	The estimated burden hours and costs are:

totals			160/$19,840	160/$27,840	540/$66,960	540/$19,440	1400/$134,080

	Capital/start-up costs for the literature search are estimated at
$10,000 for the purchase of computer hardware/software for recording the
search and the purchase of filing cabinets for storage.  Operating and
maintenance costs are estimated at $2000 for computer maintenance,
document storage, and shipping of the report and documents to EPA.  This
research takes less than a year and thus these costs are annualized
costs.

Worksheet 2: Tier 1 Emissions Characterization

	The estimated hours and costs are:

Activity		mgmt		legal		prof/tech	clerical

totals			160/$19,840	160/$27,8400	740/$91,760	740/$26,6400	1800/$166080

	 

	Capital/start-up costs are estimated at $25,000 for the purchase of
test engines and computer hardware/software.  Operating and maintenance
costs are estimated at $100,000 for lease of laboratory space and test
equipment.  Thus, the total estimated cost for a Tier 1 submission is
$134,080 + $10,000 + $2,000 + $166,080 + $25,000 + $100,000 = $437,160. 

	Standard Tier 2/Alternative Tier 2/Tier 3 activity also will be very
limited.  The EPA has concluded that existing data cover Tier 2 for
baseline diesel.  Alternative Tier 2 covers baseline gasoline, the six
major nonbaseline gasoline oxygenates, and the atypical gasoline
additive MMT.  Thus, only atypical products for manufacturers with $10
million or greater in annual revenue, and new gasoline oxygenates for
manufacturers with $50 million or greater in annual revenue, remain that
are subject to the standard Tier 2or Alternative Tier 2 requirements. 
While EPA has yet to require a Tier 3, it is likely to have a burden
similar to that for Tier 2/Alternative Tier 2.  EPA estimates that there
will be three standard Tier 2/Alternative Tier 2/Tier 3 submittals over
the next three years, at an estimated annualized cost of about $2
million each.    

Worksheet 3: Tier 2/alternative Tier 2/Tier 3 Inhalation Research

totals			640/$79360	640/$111360	9360/1160640 5360/$192960	

grand total		16000/$1,544,320

	Capital/start-up costs are estimated at $150,000 for the purchase of
animals, cages/related equipment, and computer hardware/software. 
Operating and maintenance costs are estimated at $250,000 for the lease
of laboratory space and test equipment, and animal supplies.  Thus, the
total estimated cost for a Tier 2 submission is $1,544,320 + $150,000 +
$250,000 = $1,944,320

	It is estimated that API will spend $450,000 per year, including
$20,000 per year in capital/start-up (C/S) costs and $30,000 per year in
operating and maintenance (O&M) costs, over the next three years in
conducting its Alternative Tier 2 animal testing.  Subtracting C/S and
O&M costs from the $450,000 leaves $400,000, and assuming an average of
$200 per hour for labor and benefits for this specialized Alternative
Tier 2 animal research, results in an annual burden of 2,000 hours.  It
is assumed that API will submit one report per year.  The reasons for
the C/S and O&M costs are the same as in the previous paragraph for Tier
2 inhalation research.

	

	6(c)	Estimating Agency Burden and Cost

	It is estimated that the EPA will expend about one-half of a Full Time
Equivalent (FTE) annually, allocated among several professionals, for
the activities listed in section 5(a). Assuming $80 per hour, for
government salary and overhead at the professional level, gives an
annual cost of $83,200 to the EPA.  Costs for storage and public
availability will be nominal.

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

	As discussed, it is anticipated that Tier 1 and standard Tier
2/Alternative Tier 2/Tier 3 activities will be very limited, with three
Tier 1 submissions and three Tier 2/Alternative Tier 2/Tier 3
submissions over the next three years, at an estimated cost of $0.44
million for each Tier 1 and $1.95 million for each Tier 2/Alternative
Tier 2/Tier 3, for an annual burden of about $2.4 million.  Adding $0.45
million per year for API gives an annual industry burden estimate of
$2.85 million.  The estimated annual EPA burden is $83,200.

	6(f) 	Reasons for Change in Burden

	The API testing program has reduced activity as it nears completion. 
The Afton test program has been completed.  Other activities are
estimated to be at about the same level.
