The correct response highlights that any new underground storage tank (UST) installation in California must adhere to all applicable environmental standards and secure the necessary permits prior to installation. This is crucial because these regulations are designed to protect public health, safety, and the environment from potential hazards associated with USTs, such as leaks that could contaminate soil and groundwater.

Compliance with environmental standards ensures that the materials and technology used in the installation meet safety and performance benchmarks that minimize risks. Obtaining permits serves as a regulatory check, ensuring that an installation is evaluated and approved by local authorities before construction begins. Failure to meet these requirements can lead to significant legal penalties, environmental impacts, and safety hazards.

The other options are not accurate representations of the regulations. While certain materials may be favored for their resistance to corrosion or leaks, there is no blanket requirement that all new tanks must be made of concrete. Additionally, using fiberglass or any other specific material does not exempt a project from obtaining the required permits. Lastly, there is no specified timeframe, such as one month, stated in the California UST Regulations that mandates how quickly installations must be completed, as timelines can vary based on project scope and compliance complexities.
