Rules Under Development

Board of boiler rules -- Substantive

Chapter 296-104, WAC

All updates for this rule:


The Board of Boiler Rules is proposing amendments to Chapter 296-104 WAC, Board of Boiler Rules Substantive to adopt new safety code requirements and a housekeeping change. The boiler rules are reviewed on a regular basis to ensure the rules are consistent with national boiler and unfired pressure vessel safety standards and industry practice. Due to the rulemaking moratorium, the board of boiler rules didnt adopt rules to align with the 2013 (current edition) National Board Inspection Code (NBIC), used to regulate the industry. Proposed amendments to this chapter will:

  • Adopt the 2013 (current edition) National Board Inspection Code (NBIC) requirements for boilers and unfired pressure vessels in the state of Washington;
  • Adopt the current revision of the National Board NB-263 standards, rules for national board in-service and new construction inspectors; and
  • Remove an obsolete reference to provide rule clarity and consistency in the rules.
