NECESSITY, FUNCTION, AND CONFORMITY: HB 492 (1988 Acts) directs the Cabinet for Health Services to regulate the design and construction of water distribution and treatment systems for swimming pools. KRS 211.180 directs the Cabinet for Health Services to adopt administrative regulations relating to public facilities, and their operation and maintenance in a safe, sanitary manner to protect public health and prevent health hazards. This administrative regulation establishes uniform standards for public swimming pools and other swimming or bathing facilities. The function of this administrative regulation is to assure the proper design and construction of new facilities as related to water distribution and treatment systems, and the proper operation and maintenance of all such facilities in a manner which will protect the public health. Executive Order 96-862, effective July 2, 1996, reorganizes the Cabinet for Human Resources and places the Department for Public Health and its programs under the Cabinet for Health Services.
