                Subpart D_Testing Production-line Engines
 
Sec. 1051.340  When may EPA revoke my certificate under this subpart 
and how may I sell these vehicles again?

    (a) We may revoke your certificate for an engine family in the 
following cases:
    (1) You do not meet the reporting requirements.
    (2) Your engine family fails to comply with the requirements of this 
subpart and your proposed remedy to address a suspended certificate 
under Sec. 1051.325 is inadequate to solve the problem or requires you 
to change the vehicle's design or emission-control system.
    (b) To sell vehicles from an engine family with a revoked 
certificate of conformity, you must modify the engine family and then 
show it complies with the requirements of this part.
    (1) If we determine your proposed design change may not control 
emissions for the vehicle's full useful life, we will

tell you within five working days after receiving your report. In this 
case we will decide whether production-line testing will be enough for 
us to evaluate the change or whether you need to do more testing.
    (2) Unless we require more testing, you may show compliance by 
testing production-line vehicles or engines as described in this 
subpart.
    (3) We will issue a new or updated certificate of conformity when 
you have met these requirements.
