HAR §11-10-16. Public saltwater specialty swimming pools

(a) Water quality: (1) The water shall have sufficient clarity at all times so that a disc which is six inches in diameter and of a color of high contrast to the color of the public saltwater specialty swimming pool bottom can be seen from outside the pool when placed on the bottom of the public saltwater specialty swimming pool at the deepest point. The public saltwater specialty swimming pool shall be immediately closed if the public saltwater specialty swimming pool fails to meet this requirement. (2) When bacteriological samples are collected for laboratory analysis, the geometric mean of the most recent five consecutive enterococcus counts cannot exceed 7.0 CFU/100 ml of pool water. (3) The water quality requirements provided in paragraphs (1) and (2) shall be satisfied as follows: (A) In a closed system, the water shall be disinfected by using disinfecting agents approved by the United States Environmental Protection Agency or processes approved by the National Sanitation Foundation. The agents or processes used in controlling water quality shall not be dangerous to public health, create objectionable physiological effects, or impart toxic properties to the pool water. Any agent that is to be used for algae control shall be approved by the department before use. 13 (B) In an open system, the water quality requirements shall be satisfied through pool water circulation. The pool water shall be completely exchanged at least once every six hours. (4) All public saltwater specialty swimming pool water samples shall be examined by a laboratory or methods employing suitable sensors or monitoring technology approved by the department. Where applicable, analysis to determine compliance with this chapter shall be by: (A) Standard Methods for the Examination of Water and Wastewater, Twentieth Edition, APHA; (B) “Guidelines Establishing Test Procedures for Analysis of Pollutants”, Federal Register, July 1, 1998 (40 CFR 136) and “Technical Amendments”, Federal Register, July 1, 1998 (40 CFR 136); (C) “Methods of Seawater Analysis”, Second Revised and Extended Edition, ed. by K. Grashof, M. Erhardt, K. Kremling, 1983, Verlag Chimie, Weinheim, Germany; and (D) EPA/600/4-79-019, Handbook for Analytical Quality Control in Water and Wastewater Laboratories, March 1979. (5) All public saltwater specialty swimming pools shall be continuously free of non-microbial hazardous marine life. (6) Failure to meet the requirements set by this section shall constitute grounds for immediate closing of the public saltwater specialty swimming pool. The operator may reopen the public saltwater specialty swimming pool for public use when the department determines that all requirements of this section have been met and there is no immediate risk to human health. (b) A monitoring plan, quality control/quality assurance plan, and maintenance and management plan shall be submitted and approved by the director prior to opening a public saltwater specialty swimming pool for use. (c) Monitoring plan guidelines: (1) Public saltwater specialty swimming pool water circulation must be measured to guide the initial selection of sampling locations including but not limited to the range of water residence times 14 across the entire water column in the public saltwater specialty swimming pool. (2) Water clarity shall be monitored at least daily at the time of peak use. (3) Fecal indicator bacteria (enterococci) in the water column shall be monitored at least weekly. (4) Fecal indicator bacteria shall be monitored, for example, at multiple stations along spatial gradients at the surface, near the bottom, in the middle of the water column, and near corners and sidewalls. Nearby sites outside the public saltwater specialty swimming pool that are representative of the near-shore coastal environment shall also be monitored for comparative purposes. (5) The pool water exchange rate of at least once every six hours shall monitored on a daily basis. (d) The public shall be informed by a placard that a public saltwater specialty swimming pool is not disinfected. [Eff JUL 15 2002 ][Auth: HRS §§321-10, 321-11][Imp: HRS §321-11]
