Development of Cost Estimates of Fuels and Fuel Additives

The purpose of this memorandum is to provide information 

showing how cost estimates in the Regulatory Support Document were 

developed. The first attachment provides estimated cost data 

specific to each registration requirement, including costs of data 

research and analysis, emission characterization, emission 

generation, and biological testing. Attachment 2 provides a 

summary of estimated costs for each Tier. Contained in the third 

attachment are cost estimates applicable to each category (fuel 

family X formulation class) of products. These estimates are based 

on broad judgements regarding the probable testing needed for those 

products likely to be sorted into each category. 

The individual costs were developed a few months prior to 

publication of the NPRM. Since that time, minor revisions were 

made to some of the proposed program provisions. For example, the 

categorization of products for purposes of the cost analysis 

assumed an oxygen content of two percent would function as the cutoff point between products in the baseline and non-baseline 

formulation classes. However, the current proposal presents two 

different alternatives for distinguishing baseline from nonbaseline products: an oxygen content of 1.5 percent in the first 

alternative and 2.7 percent in the second alternative. 

Furthermore, since the cost estimates were developed, the proposed 

data modeling requirements in Tier 1 were increased, and some of 

the proposed Tier 2 health effects test guidelines were modified 

slightly. Unfortunately, the cost estimates could not be updated 

to reflect these late changes, and thus, may not be entirely 

representative of the requirements as now proposed. Nevertheless, 

the cost estimates are not overly sensitive to these changes and 

the overall costs are reasonably accurate to the degree of 
P.3 

precision of the individual cost estimates and judgements used to 

assess the overall economic impact.

*Vehicle accumulates 110,000 miles per year(55mph x 8hr/day x 

5day/wk x 50 wk/yr). Useful life = 290,000 miles. Thus, 

UL - 2.6 years (290,000/110,000). Engine operates 2000 hours/yr 

(40 hr/wk x 50 weeks). Assume miles accumulated to 50% 

of useful life, or 1.3 yrs (2.6 x 50%). Therefore, total hours of running

Explanation of Combined Test Costs 

Ames Reverse Mutation Assay 

Due to the technical difficulty and expense of 

testing gaseous samples with this assay, a separate 

Salmonella typhimurium Reverse Mutation (Ames) assay is 

required for both the particulate and the semi-volatile 

fractions of a product's exhaust emissions (each at an 

estimated cost of $4100) but not on the gaseous portion 

of those emissions. Likewise, as evaporative emissions 

are seen as having only a gaseous component, a product's 

evaporative emissions are not subject to testing in this 

particular assay. Because this assay does not require 

testing of laboratory animals, it cannot be combined with 

any of the other proposed screening tests. 

Combined Teratogenicity and Neurotoxicity Screens (Rat), 

in conjunction with Combined Pulmonary Toxicity, Reproductive Toxicity, and Teratogenicity Screens (Mouse) 

For purposes of the cost analysis, EPA assumed that 

Teratogenicity and Neurotoxicity screens using rats would 

be combined for testing purposes, and similarly, the 

Reproductive Toxicity, Pulmonary Toxicity, and Teratogenicity screens using mice would be combined. These 2 test 

blocks would be conducted concurrently using the same 

sample of diluted emissions, assuming laboratory facilities had the capability of conducting these tests 

simultaneously. 

By increasing the number of test atmosphere-exposed 

animals in any one study, it is possible to run 1-2 more 

studies concurrently on the "excess" animals in each test 

population. The two screening assays for teratogenicity 

require separate mouse and rat test populations. 

Multiple studies requiring either species may be run in 

conjunction with each of the teratogenicity screens. The 

rats needed for the Functional Observational Neurotoxicity Battery (FONB) may be housed and exposed simultaneously with the rat test population for the teratogenicity screen in rats. The mice needed for both the Subacute Pulmonary Toxicity Study and the Reproduction and 

Fertility Screen may be housed and exposed simultaneously 

with the mouse test population for the teratogenicity 

screen in mice. Savings are realized in not having to run 

five separate exposures nor having to house five separate 

test populations. Furthermore, running multiple studies 

at the same time in close physical proximity reduces the 

number of professional and technical person-hours 

expended and lowers the "overhead" and direct supply 

costs of the testing program for the facility. 

In the combined scenario, pulmonary effects are 

tested in mice, while the testing guidelines recommend 

that the Sub-acute Pulmonary Toxicity Study be run on 

rats. In apportioning pulmonary and neurotoxicity testing 
P.15 

to either of the two test populations, rat or mouse, the 

pulmonary study is more easily adapted to testing in mice 

than the functional neurotoxicity study which, historically, has been run in rats. Consequently, the combined 

scenario recommends testing for pulmonary effects in the 

mouse population. 

Combined Rodent Bone Marrow Screens 

The rat is the recommended test animal in both the 

Sister Chromatid Exchange (SCE) and Micronucleus (MN) 

assays. As each assay requires that different tissues be 

harvested for analysis (lung cells, peripheral blood for 

SCE and bone marrow for MN) , both assays can be run 

concurrently in the same rodent test population. A one 

third cost savings results from having to maintain and 

expose only half the number of rodents needed for two 

separate assays.
