Sec.  1039.210  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

control devices, deterioration factors, testing for service 
accumulation, maintenance, and NTE deficiencies and carve-outs. 
Decisions made under this section are considered to be preliminary 
approval, subject to final review and approval. 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
