A piping plan is a critical component in the design and installation of gas systems. Including the available supply pressure on a piping plan is essential because it helps determine the sizing and layout of the gas piping system. The supply pressure affects the flow rate of gas through the system and the selection of components, such as valves and regulators, that can adequately handle the expected operating conditions. It ensures that the system operates efficiently and safely, preventing potential overpressure situations that could lead to damage or hazards.

While other options may be relevant in different contexts, they do not specifically pertain to the fundamental elements needed in a piping plan. The type of gas supplier might inform some operational guidelines but is not a standard requirement for the piping plan itself. An environmental impact assessment is typically more relevant for project approvals rather than the technical specifications of piping. Regulatory compliance documentation, while crucial for legality and safety, is often a separate component that accompanies broader project documentation rather than being a specific requirement of the piping plan.
