If you send us information before you finish the application, we will review it and make any appropriate determinations listed in Sec. 1051.215(b)(1) through (5). Decisions made under this section are considered to be preliminary approval. We will generally not disapprove applications under Sec. 1051.215(b)(1) through (5) where we have given you preliminary approval, unless we find new and substantial information supporting a different decision. (a) If you request preliminary approval related to the upcoming model year or the model year after that, we will make a ``best-efforts'' attempt to make the appropriate determinations as soon as possible. We will generally not provide preliminary approval related to a future model year more than two years ahead of time. (b) If we have published general guidance that serves as our determination for your situation, you may consider that to be preliminary approval.
