Updating the professional engineers' registration act.

SB 5090 updates Washington's Professional Engineers' Registration Act by modernizing definitions and board composition. It removes outdated language and clarifies terms like "practice of engineering" and "significant structures" (e.g., defining hazardous facilities and large buildings). The bill requires board members to have at least 10 years of active practice in engineering or land surveying, including five years immediately prior to appointment. This affects the Board of Registration for Professional Engineers and Land Surveyors and the professionals they regulate, without changing core registration requirements for engineers or land surveyors.
