Process and environmental protection is covered in a general fashion in Section 6. Where required, specific instances of process and environmental protection are covered in Sections 2 - 5.

Tank gauging is outside the scope of Section 3. The applicable publication is referenced in that section.

Where appropriate, installation drawings, cautionary notes, and explanations are included. Valves and piping that are typically covered in piping standards have been omitted from most installation drawings.
