What are the fees for a CUA?
A $100 application/administrative fee for each service category is due with the application. This fee is non-refundable.
Why does the park charge a fee for a CUA?
National Park Service Policy requires the Superintendent to charge a reasonable fee for CUAs. The park retains such fees to help pay for the cost of the CUA program, including administration, evaluations, monitoring and training.
How long does it take to obtain a CUA?
You should anticipate that you will receive the issuance of a CUA a minimum of 7-10 business days after we receive the application. Delays will occur if application materials are not submitted accurately or completely, or if authorizations needing operator signature are not returned promptly. All required documentation must be received before the CUA will be issued.
