Non-OEM Component Certification
Program for Locomotives —
40 CFR 1033.645
What components may be certified under the provisions of 40 CFR 1033.645?
Components commonly replaced during remanufacturing may be certified under the
provisions of 40 CFR 1033.645. Certification is not available for components that
t:
are replaced during a locomotive's useful life but not typically replaced during reman-
ufacturing. However, once certified, components may be used for remanufacturing
-------
locomotives that use that certified component. We may require in use testing of one locomotive
for each additional 1000 locomotives beyond that. These numbers apply across model years, and
do not count locomotives that use your components that are not certified. The first locomotive
tested must have operated between 25 and 50 percent of its useful life in terms of MW-hours,
and all others must have operated beyond the half-way point of their useful lives. You must
complete testing and report the results within 180 days of the earliest point at which you could
complete testing based on the operation accumulated by the locomotives, and must test the
locomotive according to procedures specified in EPA's rules, unless we approve otherwise. If any
locomotives fail to meet all standards, we may require you to test one additional locomotive
for each one that fails. You may ask us to rely on testing performed by others instead of requir-
ing you to perform testing, and in unusual circumstances you may ask us to grant you hardship
relief from the testing requirements. In determining whether to grant you hardship relief, we will
consider all relevant factors including the extent of the financial hardship to your company and
whether the test data are available from other sources, such as testing performed by a railroad.
[40 CFR 1033.645 (d)]
May I use uncertified, non OEM components for maintenance?
Yes. The provisions of 40 CFR 1033.815 do not require use of certified components in main-
tenance. However, section 1033.815(c) requires that you use good engineering judgment and
perform all maintenance and repair such that you have a reasonable technical basis for believing
the locomotive will continue to meet the applicable emission standards and FELs to which it
was certified.
If I remanufacture a locomotive using a certified kit, may I use components supplied by an
entity other than the provider of the certified kit?
Yes. For basic mechanical parts including oil coolers, intake and exhaust valves; intake and
exhaust valve retainers, springs and rotators, the kit provider may include design specifications
addressing dimensions and material constraints as necessary, as well as part numbers as long as it
is made clear that alternate part suppliers may be used. Assembly instructions may not include
specifications for parts unrelated to emissions and may not specify a part manufacturer unless
EPA determines that such specification is necessary. [40 CFR 1033.130 (e)] Additionally, you
may use appropriate components certified under the provisions of 40 CFR 1033.645.
