- Effects

Research Requirements for Manufacturers (40 CFR part 79 , s ubpart F) EPA I CR Number 1696.0 6 , OMB Control Number 2060

- 0297 1(b) Abstract In accordance with the regulations at 40 CFR part 79, s ubparts A, B, C, D and F (there is no Subpart E), Registration of Fuels and Fuel Add itives, manufacturers of (1) motor vehicle gasoline, (2) motor vehicle diesel fuel, and (3) additives for those fuels, are required to have their products registered b y the Environmental Protection Agency (EPA) prior to their introduction into commerce. R egistration 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 I CR 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 (in dicating 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 In stitute (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 exposur es 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 test ing 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 b y the Eth yl 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,2

welfare effects, and/or emissions exposures from a fuel or fu el/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 5 00 fuel manufacturers, 1,0 00 additive manufacturers, 7 00 registered fuels, and 6, 70 0 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 emissio ns in the United States. Congress demonstrated its strong concern for the protection of public health b y providing broad legislative authority to monitor and regulate fuels, fuel additives, and their emissions. This registration program was established b y 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, b y regulation, any mobile source fu el 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 registe red b y 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 b y the Department of Health, Education, and Welfare in 1970 and transferred to the EPA shortly

there after. They

ultimatel y 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, s ubpart F, promulgated on May 27, 1994, require research for each of the following fuel/additive groups whose components are derived from conventional petroleum, heav y oil deposits, coal, tar sands and/or oil sands: (1) Gasoline Baseline Group

- gasoline/additive elements are limited to carbon, h ydrogen, ox ygen, nitrogen and sul f

ur (for convenience, hereb y referred to as CHONS), gasoline oxygen content is less than 1.5 weight percent, and the gasoline meets the American Society for Testin g 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 ox ygenate (e .g., ethanol).3

Aty pical Group

- a group is established for each non

- CH ONS 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 oxyg en content is 1.0 weight percent or greater, and the fuel meets ASTM specifications. A group is established for each ox ygenate. An exception is biodiesel, which is one group, even though it consists of mixed alkyl esters of plant and/or animal origin. Aty pical 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 b y May 27, 1997, or evidence of a contract that would provide the Tier 2 data b y May 27, 2000. For products curr entl y 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 produc ts, 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 stu dies, 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 sul f ur content of gasoline and diesel fuel, have been regulated under this section.4

The re 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 merel y re - label a registered product are not subj ect 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, eth yltertiary butylether (ETBE), methyl tertiary butyl ether (MTBE), tertiary am ylmethyl 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 aty pical gasoline groups and five aty

pical 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 we re 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 Tie r 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 m ixture of ethanol, diesel and biodiesel. In 2008 Tier 1 data were submitted for NExBTLRenewable Diesel and Nextfuels, Inc. biodiesel. In 2009 Tier 1 data were submitted for two renewable diesels. On August 20, 1997 the APIwas informed of proposed Alt ernative 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 o n 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 alternativ e 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

. Altern ative 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 as sess 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.5

The data may

also be used by

non - EPA organizations, such as fuel/additive produ cers 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 sh are 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. Acade mic 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 Agen cy 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, CONSUL TATIONS, AND OTHER COLLECTION CRI TERIA 3(a) Non
- duplicati on 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 representati ve of the group, thus minimizing duplicative testing. 3(b) Public Notice A Federal Register notice requesting public comment on this I CR was published on September 9, 2009 (74 FR 46422)

. No comments were received. 3(c) Consultations Burden e stimates 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) Co nfidentiality 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 to6

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.

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 description7

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, anal yt ic metho ds, and results. This requirement can be mitigated b y 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 exposur e of lab animals t o combustion emissions, and in separate testing, if applicable, to evaporative emissions, for screening of general toxicity , carcinogenicity , mutagenicity , adul t reproduction/teratogenicity , pulmonary

toxicity , and neurotoxicity for Tier 2, or related nego tiated testing for Alternative Tier 2. This requirement can be mitigated b y 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 anal ys is 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 requi rements 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.8

5. THE INFORMATION COLLECTED

-- AGENCY AC TIVI TI ES, 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 regulation s; 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 b y 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 b y the Office of Transportation and Air Quality and the O ffice 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 process ing. The reports will be available to the public in hard cop y, and, if so submitted, electronicall y. 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 som e or all of these requirements. 5(d) Collection Schedule There is no schedule. The requirements appl y 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 onl y 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 ye ars. However, manufacturers of baseline and nonbaseline products with less than $509

million in annual reve nue 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 categorie s, with an estimated Tier 1 cost of about $35 0 ,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. Thu s, 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 involvem ent: managerial, legal, professional/technical (prof/tech), and clerical. According to the Bureau of Labor Statistics, May 2008 National Industry

- Specific Occupational Employ ment and Wage Estimates , mean wages were: Managerial $60.42 per hour Legal $84.56 per hour Prof/Tech $ 60.05 per hour Clerical $1 7.34 per hour D oubling for compan y overhead beyond and employing a 2% annual inflation factor to bring the rates to 200 9 , and, for convenience, rounding up to the even dollar, gives the following rate s that will be used in this I CR: 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 I CR. We believe that the pre vious hourl y burden estimate is still representative, on average.

- 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 $2000 for computer maintena nce, document storage, and shipping of the report and documents to EPA. This research takes less than a year and thus these costs are annualized costs. Worksheet 2: Tier 1 Emissions Characterization The estimated hours and costs are: Activity mgmt l egal prof/tech clerical read regs 40/$ 496 0 40/$ 696 0 40/$ 496 0 40/$ 1440 obtain data 40/$ 496 0 40/$ 696 0 500/$ 62 ,000 500/$ 18 ,000 review data 40/$ 496 0 40/$ 696 0 100/$ 12,40 0 100/$ 36 00 prepare report and send to EPA 40/$ 496 0 40/$ 696 0 100/$ 12,40 0 100/$ 36 00 totals 160/$1 9,84 0 160/$ 27,84 00 740/$ 91,76 0 740/$2 6,64 00 1800/$1 66080 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 $ 10 0,000 for lea se of laboratory

space and test equipment. Thus, the total estimated cost for a Tier 1 submission is $ 134,08 0 + $10,000 + $2,000 + $1 66,08 0 + $25,000 + $ 10 0,000 = $ 437 , 16 0. 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 ox yg enates, and the atypical gasoline additive MMT. Thus, only

atypical products for manufacturers with $10 million or greater in annual revenue, and new gasoline ox ygenates 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 Ti er 3, it is like l y 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 ye ars, at an estimated annualized cost of about $ 2 million e ach.11

Worksheet 3: Tier 2/alternative Tier 2/Tier 3 Inhalation Research The estimated hours and costs are: Activity mgmt legal prof/tech clerical read regs 160/$1 984 0 160/$ 2784 0 160/$1 984 0 160/$ 576 0 obtain data 160/$1 984 0 160/$ 2784 0 8000/$ 992 000 4000/$1 44 000 review data 160/$1 984 0 160/$ 2784 0 800/$ 992 00 800/$ 288 00 prepare report and send to EPA 160/$1 984 0 160/$ 2784 0 400/$ 496 00 400/$1 44 00 totals 640/$ 7936 0 640/$ 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, 544,32 0 + $150,000 + $250,000 = $1, 944,32 0 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 ye ar in operating and maintenance (O&M) costs, over the next three ye ars in conducting its Alternative Tier 2 animal testing. Subtracting C/S and O&M costs from the $ 450,00 0 leaves $ 400,000 , and assuming an average of $ 2 00 per hour for labor and benefits for this specializ ed Alternative Tier 2 animal research, results in an annual burden of 2 ,000 hours. Itis assumed that APIwill 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 $ 83,2 00 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 Ti er12

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 $ 83,2 00. 6 (e) Bottom L ine Burden Hours and Cost Table Worksheet 4: Annual Industry Burden Activity Number Capital/Start
