The bill aims to enhance the consistency in the classifications of water systems in Washington State by amending existing definitions and regulations. Key changes include the clarification of the definitions for "Group A public water system" and "Group B public water system." Specifically, the bill establishes that a Group A public water system is defined as one with 15 or more service connections, or serving an average of 25 or more people per day for 60 or more days within a calendar year, or serving 1,000 or more people for two or more consecutive days. Additionally, it introduces a provision that prevents the use of a default number of people served per connection to misclassify a water system that should be classified as Group B into Group A.

Furthermore, the bill allows local governments to set separate operating permit requirements for public water systems, contingent upon approval from the Department of Health, ensuring that these local requirements do not duplicate those imposed by the department. It also specifies that local governments can establish additional requirements for Group B public water systems, provided they are at least as stringent as state requirements. The act is declared an emergency measure, taking effect immediately to preserve public health and safety.
