What is a primary reason for requiring written plans in underground storage tank installations?

The requirement for written plans in underground storage tank installations primarily exists to facilitate the process of obtaining permits and soliciting bids. Written plans serve as a detailed outline of the project scope, safety measures, and compliance with regulatory frameworks. These documents provide essential information to regulatory bodies, ensuring that the installation adheres to local, state, and federal laws.

Moreover, having comprehensive written plans allows potential contractors to understand the specific needs and expectations of the project, enabling them to submit accurate bids. This level of detail helps ensure that all contractors are comparing "apples to apples" when it comes to the project requirements, which contributes to transparency and can lead to more competitive pricing. Overall, written plans play a critical role in ensuring that the installation process is well-organized, compliant, and efficient.
