Shouldn't be any problem.
From a current booklet I have:
Try most large Post Offices. Need it in a REAL HURRY? Expedited Service$60.00 additional, but you don't seem to be in that stuation.
Routine service is within 6 weeks.
You mail be able to do it by mail. FOrm DS-82 (White text on purple blocks).
(4) questions to be answered as yes or no as follows:
1. Can I submit my most recent US Passport?
2. I was at least 16 when my most recent US passport was issued?
3. Most recent passport issued less than 15 years ago?
4. I use the same name as on my most recent US Passport OR I have had my name changed by marriage or Court order and can submit proper documentation to relect my name change.
You will need two new photos.
If you answered NO to ANY question you cannot renew by mail.
You must then use Form DS-11 by making a personal appearance before a passport agent, POSTAL CLERK or clerk of the Court authorized to accept passport applications. (White text on orange blocks)
You will need two new photos.
Current Cost: $97.00 + any expedited services.
