The U.S. Fish and Wildlife Service awarded a $18,088 firm-fixed-price purchase order to Caracal Enterprises, LLC, doing business as Ventek International, for the provision of an electronic fee station at the Rocky Mountain Arsenal National Wildlife Refuge in Colorado. The fee station will be used to collect secure credit card payments for the refuge's fishing program, which runs from April to November each year. This sole-source award was made under simplified acquisition procedures, as the agency determined Ventek International as the only responsible source that can meet its requirements, which include payment processing, solar power, cellular connectivity, custom branding, and vendor training. Ventek International is a small disadvantaged business that specializes in automated fee collection systems for various federal agencies, including the Army Corps of Engineers, National Park Service, and Bureau of Reclamation. The company holds several IDIQ contracts with the Army Corps of Engineers for similar fee machine installations and services.
