Nev. Admin. Code § 590.460
All loading and unloading connections at dealer plants must be secured to a steel bulkhead or an equivalent device designed to withstand a horizontal pull of at least 2,000 pounds in any direction unless other adequate protection is provided. This bulkhead must not be located underneath the tank. The loading and unloading connections must be firmly secured to the bulkhead, and the line between the bulkhead and tank must be installed in a manner to provide for expansion, contraction, jarring, vibrations and settling. The bulkhead must be located at least 25 feet away from the nearest important building or line of adjoining property. When in the opinion of the Board the bulkhead is necessary for the safety of the place of employment, it must be required at storage plants other than dealer plants.
