Changes to Adopted Codes:

• NAC 455C.108: The Pressure Vessel Inspection Code: In-Service Inspection, Rating, Repair, and Alteration, API 510, 2014 Edition and the Hydrogen Technologies Code, NFPA 2, 2020 Edition are both now adopted by reference.
• NAC 455C.108 / 500: These sections have been changed to remove the provision for automatic adoption by reference of the various safety codes used by the Mechanical Compliance Section (MCS), including the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, the ASME A17 series of elevator safety codes, the National Board Inspection Code, and others. Revisions to these code adoptions must now be made through the regulations process, which includes a public workshop and a public adoption hearing.

Additionally, administrative fines and/or penalties may now be delivered by an inspector where previously such documents must have been delivered only via certified mail.

Changes to Provisions Regarding Certifications:
