Sec.  1048.210  May I get preliminary approval before I complete my application?

    If you send us information before you finish the application, we 
will review it and make any appropriate determinations, especially for 
questions related to engine family definitions, auxiliary emission-
control devices, deterioration factors, testing for service 
accumulation, and maintenance. Decisions made under this section are 
considered to be preliminary approval, subject to final

review and approval. We will generally not reverse a decision where we 
have given you preliminary approval, unless we find new information 
supporting a different decision. If you request preliminary approval 
related to the upcoming model year or the model year after that, we will 
make best-efforts to make the appropriate determinations as soon as 
practicable. We will generally not provide preliminary approval related 
to a future model year more than two years ahead of time.
