Commercial Use Authorization

 

What is a CUA?

A Commercial Use Authorization (CUA) is a business permit with the National Park Service (NPS) that authorizes an individual, group, company, or other for-profit entity to conduct commercial activities and provide specific visitor services within a national park area. The National Park Service will only issue CUAs for commercial activities and visitor services that:

  • are determined to be an appropriate use of Mammoth Cave National Park;

  • will have minimal impact on Mammoth Cave National Park’s resources and values; and

  • are consistent with Mammoth Cave National Park’s purpose, management plans, policies, and regulations.

Do I Need a CUA?

A CUA is required if you, as an individual, organization, or company, provide any goods, activities, services, agreements, or other function for members, clients, or the public that:

  • take place at least in part in Mammoth Cave National Park,

  • use park resources, and

  • result in compensation, monetary gain, benefit, or profit.

Businesses and individuals may not conduct commercial activities in the park without a valid CUA or in a manner inconsistent with the terms of the CUA. You must be in possession of a valid CUA to conduct business in Mammoth Cave National Park.

How much does a CUA cost?

Application Fee (application fees are NON-REFUNDABLE): $350 for first application, $250 for subsequent applications to same park in same calendar year.

Management Fee: In addition to the application fee, The NPS must charge CUA holders a management fee that, at a minimum, recovers the costs of all CUA management after application approval. CUA management includes, but is not limited to, correspondence with the CUA holder, in-the-field monitoring, and mitigation of resource impacts caused by commercial activity.
