What is a common requirement for UST installation?

The requirement that tanks must be certified and meet state specifications is vital for UST installation because it ensures that the tanks are designed and constructed to safely store petroleum and hazardous substances. These specifications typically include standards for materials, construction methods, spill prevention, leak detection, and other safety measures to minimize risks to the environment and public health. Compliance with state specifications also governs the installation process, ensuring that all safety regulations are followed, thereby reducing the potential for accidents and environmental contamination.

In contrast, the other options do not align with the regulatory framework governing UST installations. Installing all tanks above ground is not a universal requirement as underground tanks are a common form of storage. The notion that tanks must be installed without any permits is incorrect, as permits are typically required to ensure compliance with local, state, and federal regulations. Finally, while it may be beneficial for owners to be licensed fuel distributors, it is not a standard requirement for the installation of USTs, as ownership and distribution can vary widely among tank owners.
