# §1068.445. When may EPA revoke my certificate under this subpart and how may I sell these engines/equipment again?

- (a) We may revoke your certificate for a family in the following cases:
  - (1) **You do not meet the reporting requirements under this subpart.**
  - (2) Your family fails an SEA and your proposed remedy to address a suspended certificate is inadequate to solve the problem or requires you to change the engine/equipment's design or emission control system.
- (b) To sell engines/equipment from a family with a revoked certificate of conformity, you must modify the family and then show it complies with the applicable requirements.
  - (1) If we determine your proposed design change may not control emissions for the engine/equipment'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 engines/equipment as described in this subpart.
  - (3) We will issue a new or updated certificate of conformity when you have met these requirements.
