Hi Tim, I have applied for study permit and I did not mention my USA?
The fact that you renewed your passport is irrelevant. Your previous visa refusal will still be found. Since a student visa, like a visitors visa, is a non-immigrant visa its likely that the previous refusal was driven by doubts about your intentions to leave the US upon the expiration of your stay. You can anticipate, at best, a more rigorous review of your request for a student visa.
