PERMANENT RULES

DEPARTMENT OF

LABOR AND INDUSTRIES

[Filed December 19, 2017, 11:25 a.m., effective January 31, 2018]

Effective Date of Rule: January 31, 2018.

Purpose: The purpose of this rule making is to adopt amendments to sections in chapter 296-104 WAC, Board of boiler rules—Substantive, to update and clarify the rules and for technical changes. 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. This rule making will:

•	Adopt modifications to the installation/reinstallation permit requirements to improve the permit and inspection process and create consistency for all customers on permit requirements. For example:

o	Make the "installer" of a boiler and pressure vessel responsible for permit requirements, permit fees, and civil penalties;
o	Eliminate the permit exemption for owner/user inspection agencies and Washington state specials to require permit filing, permit fees and civil penalties;
o	Create a new definition for "installer" to clarify the entity or individual responsible for permit requirements; and
o	Establish notification requirements for filing permits and emergency installations.

•	Adopt procedures for removing condemned vessels permanently from service to ensure that unsafe vessels are not returned to service for use;
•	Automatically adopt the current edition of the National Board Inspection Code (NBIC) for in-service inspection of historic steam boilers and nonnuclear repairs and alterations of boilers and unfired pressure vessels to bring the rules up-to-date and ensure the rules remain consistent with the latest national standards;
•	Adopt new definitions to define the usage status of a vessel, such as active, inactive, out-of-service, and scrapped to clarify terms and eliminate confusion for inspectors and customers; and
•	Adopt modifications to the board of boiler rules meeting schedule to hold regular meetings quarterly, as opposed to February, May, September, and November of each year to allow the board more flexibility in scheduling of meetings.

Citation of Rules Affected by this Order: Amending WAC 296-104-010, 296-104-015, 296-104-020, 296-104-102, 296-104-502, 296-104-700, and 296-104-701.
