I'd go to their website and see if there is anything about a fee to submit an application!
Well I just went into the Georgia State Park Application and it is right here:
New! ANNUAL REGISTRATION FEE
The website application edits are now in effect, you will notice when you log onto your account and click on the dates of your most recent assignment request that you are prompted to pay a mandatory annual registration fee of $15 per person. This fee covers the cost of processing your application, the fee associated with the excess accident medical insurance and excess personal liability insurance for you and processing the criminal background check. You will only need to pay this fee once per person annually. It covers volunteering with any branch of Georgia Department of Natural Resources/Georgia State Parks, Historic Sites and Golf Course. Excess insurance provides protection in excess of any other personal collectible insurance and is a requirement of volunteers. Upon receipt of your annual registration and a clear criminal history, host applicants will receive a 5-day Camping Certificate (valued at $125) that can be used at any Georgia State Park.
