(17) "Pool Deck" means the area contiguous to the outside of the pool curb, diving boards, diving towers and slides.

(18) "Pool Shell" means the rigid encasing structure of a pool that confines the pool water by resisting the hydrostatic pressure of the pool water, resisting the pressure of any exterior soil, and transferring the weight of the pool water (sometimes through other supporting structures) to the soil or the building that surrounds it.

(19) "Private Residential Pool" means a swimming pool, spa pool or wading pool used only by an individual, family, or living unit members and guests, but not serving any type of multiple unit housing complex of four or more living units.

(20) "Public Pool" means a swimming pool, spa pool, wading pool, or special purpose pool facility which is not a private residential pool.

(29) "Unblockable Drain" means a drain of any size or shape such that a representation of the torso of a 99 percentile adult male cannot sufficiently block it to the extent that it creates a body suction entrapment hazard.

(30) "Wading Pool" means any pool or pool area used or designed to be used by children five years of age or younger for wading or water play activities.

(31) "Water Slide" means a recreational facility consisting of flumes upon which bathers descend into a splash pool.

(5) Pool Water Sampling and Testing.

(a) At the direction of the Local Health Officer, the pool operator or a representative of the local health department shall collect a pool water sample from each public pool at least once per month or at a more frequent interval as determined by the Local health Officer. A seasonal public pool during the off season and any public pool while it is temporarily closed, if the pool is closed for an interval exceeding half of that particular month, are exempt from the requirement for monthly sampling. The operator or local health department representative shall submit the pool water sample to a laboratory approved under R444-14 to perform total coliform and heterotrophic plate count testing.

(b) The operator or local health department shall have the laboratory analyze the sample for total coliform and heterotrophic plate count using methods allowed under R444-14-4.

(c) If the operator submits the sample as required by local health department, the operator shall require the laboratory to report sample results within five working days to the local health department and operator.

(d) A pool water sample fails bacteriological quality standards if it:

(i) Contains more than 200 bacteria per milliliter, as determined by the heterotrophic plate count or

(ii) Shows a positive test for presence of coliform or contains more than 1.0 coliform organisms per 100 milliliters.

(e) Not more than 1 of 5 samples may fail bacteriological quality standards. Failure of any bacteriological water quality sample shall require submission of a second sample within one lab receiving day after the sample report has been received.

R392-302-28. Cleaning Pools.

(1) The operator shall clean the bottom of the pool as often as needed to keep the pool free of visible dirt.

(2) The operator shall clean the surface of the pool as often as needed to keep the pool free of visible scum or floating matter.

(3) The operator shall keep all pool shell surfaces, handrails, floors, walls, and ceilings of rooms enclosing pools, dressing rooms and equipment rooms clean, sanitary, and in good repair.

(4) The operator shall respond to all discovered releases of fecal matter into a public pool in accordance with the following protocol: Centers for Disease Control and Prevention. Fecal Accident Response Recommendations for Pool Staff and Notice to Readers--Revised Guidance for Responding to Fecal Accidents in Disinfected Swimming Venues. Morbidity Mortality Weekly Report February 15, 2008 Volume 57, pages 151-152 and May 25, 2001 Volume 50, pages 416-417, which are incorporated by reference. The operator shall include in the records required in R392-302-29(2) information about all fecal matter releases into a public pool. The records shall include date, time, and where the fecal matter was discovered; whether the fecal matter was loose or solid; and the responses taken. The Local Health Officer may approve the alteration of the required Centers for Disease Control protocol for the hyperchlorination step for a loose fecal release if an operator is able to achieve a 99.9 percent kill or removal of cryptosporidium oocysts in the entire pool system by another method such as ultraviolet light, ozone, or enhanced filtration prior to allowing bathers to reenter the pool.

R392-302-29. Supervision of Pools.

(1) Public pools must be supervised by an operator that is certified or recertified by a program of training and testing that is approved by the Utah Department of Health. The local health department may determine the appropriate numbers of pools any one certified operator may supervise using criteria based on pool compliance history, local considerations of time and distance, and the individual operator's abilities.

(2) The pool operator must keep written records of all information pertinent to the operation, maintenance and sanitation of each pool facility. Records must be available at the facility and be readily accessible. The pool operator must make records available to the department or the local health department having jurisdiction upon their request. These records must include disinfectant residual in the pool water, pH and temperature of the pool water, pool circulation rate, quantities of chemicals and filter aid used, filter head loss, filter washing schedule, cleaning and disinfecting schedule for pool decks and dressing rooms, occurrences of fecal release into the pool water or onto the pool deck, bather load, and other information required by the local health department. The pool operator must keep the records at the facility, for at least two operating seasons.

(3) The public pool owner, in consultation with the qualified operator designated in accordance with 392-302-29(1), shall develop an operation, maintenance and sanitation plan for the pool that will assure that the pool water meets the sanitation and quality standards set forth in this rule. The plan shall be in writing and available for inspection by the local health department.

The plan shall also specify who is responsible to take and record the measurements.

(4) If the public pool water samples required in Section R392-302-27(5) fail bacteriological quality standards as defined in Section R392-302-27(5), the local health department shall require the public pool owner and qualified operator to develop an acceptable plan to correct the problem. The local health department may require more frequent water samples, additional training for the qualified operator and also may require that:

(a) the pool operator measure and record the level of disinfectant residuals, pH, and pool water temperature four times a day (if oxidation reduction potential technology is used in accordance with this rule, the local health department may reduce the water testing frequency requirement) or

(b) the pool operator read flow rate gauges and record the pool circulation rate four times a day.

(5) Bather load must be limited if necessary to insure the safety of bathers and pool water quality as required in Section R392-302-27.
