Sec.  1048.250  What records must I keep and make available to EPA?



    (a) Organize and maintain the following records:

    (1) A copy of all applications and any summary information you send 

us.

    (2) Any of the information we specify in Sec.  1048.205 that you 

were not required to include in your application.

    (3) A detailed history of each emission-data engine. For each 

engine, describe all of the following:

    (i) The emission-data engine's construction, including its origin 

and buildup, steps you took to ensure that it represents production 

engines, any components you built specially for it, and all the 

components you include in your application for certification.

    (ii) How you accumulated engine operating hours (service 

accumulation), including the dates and the number of hours accumulated.

    (iii) All maintenance, including modifications, parts changes, and 

other service, and the dates and reasons for the maintenance.

    (iv) All your emission tests, including documentation on routine and 

standard tests, as specified in part 40 CFR part 1065, and the date and 

purpose of each test.

    (v) All tests to diagnose engine or emission-control performance, 

giving the date and time of each and the reasons for the test.

    (vi) Any other significant events.

    (4) Production figures for each engine family divided by assembly 

plant.

    (5) Keep a list of engine identification numbers for all the engines 

you produce under each certificate of conformity.

    (b) Keep data from routine emission tests (such as test cell 

temperatures and relative humidity readings) for one year after we issue 

the associated certificate of conformity. Keep all other information 

specified in paragraph (a) of this section for eight years after we 

issue your certificate.

    (c) Store these records in any format and on any media, as long as 

you can promptly send us organized, written records in English if we ask 

for them. You must keep these records readily available. We may review 

them at any time.

    (d) Send us copies of any engine maintenance instructions or 

explanations if we ask for them.
