Rule Development

2017 Boiler Rule Development

The Board of Boiler Rules is considering amendments to sections in Chapter 296-104 WAC, Board of Boiler Rules - Substantive for clarification and technical changes. The Board of Boiler Rules (Board) promulgates rules and regulations for the safe and proper construction, installation, repair, use, and operation of boilers and safe and proper construction, installation and repair of unfired pressure vessels in the state of Washington. 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, for rule clarity, housekeeping, etc.

Examples of changes for consideration will:

  • Amend the rules to include Installers as responsible parties for permit filing requirements for installations, paying the installation permit fee, and civil penalties for violations; and definition of installer;
  • Amend the rules to eliminate the permit exemption for owner/user inspection agencies;
  • Amend the definitions to outline procedures for “condemned boilers or unfired pressure vessels” and to define the terms used to describe the status of a vessel;
