Section 410IAC6-2.1-42.1. Tourist home pools and spas

  1. (a) Water introduced into the pool or spa at a tourist home, either directly or through the recirculation system, shall be supplied through an air gap or in accordance with 675 IAC 16.

  (b) Semi-public pools and spas at tourist homes shall meet the following:

(1) A free residual of the disinfectant chemical shall be maintained throughout the pool or spa at concentrations in accordance with the following:

	CHLORINE		BROMINE
Pool Type	Minimum	Maximum	Minimum	Maximum
Pools	1.0 ppm	7.0 ppm	2.0 ppm	10.0 ppm
Spas	2.0 ppm	7.0 ppm	4.0 ppm	10.0 ppm

(2) Whenever the residual disinfectant:

(A) falls below the minimum concentration required; or

(B) exceeds the maximum concentration allowed;

the pool or spa shall be cleared and kept free of bathers until disinfectant residuals are within the acceptable range.

(3) The pool or spa water shall be superchlorinated to breakpoint or superoxidized with a nonchlorine oxidizer when the pool test kit reveals a combined chlorine (chloramine) concentration of five-tenths (0.5) ppm or greater.

(4) Chlorinated isocyanurates or stabilized chlorine shall not be used for breakpoint chlorination.

(5) The water temperature in a spa may not exceed one hundred four (104) degrees Fahrenheit.

(6) The water in a pool or spa shall have a pH of not less than seven and two-tenths (7.2) and not more than seven and eight-tenths (7.8).

(7) The alkalinity of the water in pools and spas shall be at least eighty (80) ppm as titrated to the methyl orange endpoint.

(8) If chlorinated isocyanurate or cyanuric acid stabilizers are used in a pool, the concentration shall not exceed sixty (60) ppm. When the maximum allowable cyanuric acid concentration is exceeded, appropriate measures shall be taken to lower the concentrations to the required range.

(9) Chlorinated isocyanurates and cyanuric acid stabilizers shall not be used in a spa or in an indoor pool.

(10) Only in pools where chlorine is used as the disinfectant can cyanuric acid be used as a stabilizer.

(11) Pool and spa water shall be tested and logged for the following:

(A) pH and disinfectant residuals before each change in occupancy.

(B) Combined chlorine at least once a week when chlorine is used.

(C) Total alkalinity at least once a week.

(D) Cyanuric acid, when it is used, at least once a week.

(12) The pool or spa shall be closed for at least one (1) hour following the manual addition of a chemical directly to the water.

(13) Any chemical used to treat the water in a pool or spa must be used in accordance with the product label directions.

(14) At all times, the water in a pool shall have sufficient clarity so that the main drain or a black disc, six (6) inches in diameter placed at the deepest part of the pool, is readily visible from the deck. Water in a spa shall have sufficient clarity so, when the hydrojets are turned off, the main drain or a black disc, six (6) inches in diameter placed at the deepest part of the spa, is readily visible from the deck.

(15) One (1) water sample must be collected each month that the pool or spa is open for use and submitted for bacteriological examination. Samples may not be collected from any portion of the recirculation system. Bacteriological examinations performed on each sample shall include the heterotrophic thirty-five (35) degree Centigrade plate count and a total coliform test using either the:

(A) multiple tube fermentation test;

(B) membrane filter test; or

(C) one hundred (100) milliliter presence/absence test.

Tests shall be performed by a state-approved laboratory in accordance with the procedures outlined in Standard Methods.

(16) A copy of each water sample report must be submitted to the local health department by the pool or spa owner or operator within four (4) days of receiving such a report from the laboratory. Should a bacteriological sample collected in accordance with subdivision (15):

(A) contain more than two hundred (200) bacteria colonies per milliliter as determined by the heterotrophic thirty-five (35) degree Centigrade plate count;

(B) test positive (confirmed test) for coliform organisms in any of the five (5) to ten (10) milliliter portions of a sample when the multiple tube fermentation tube test is used;

(C) test positive for more than one (1) coliform organism per fifty (50) milliliters when the membrane filter test is used; or

(D) show the presence of any coliform when the one hundred (100) milliliter presence/absence test is used;

another bacteriological sample shall be collected from the same pool within a week of receiving notice about the original monthly bacteriological sample test results, and analyzed in accordance with subdivision (15). No two (2) consecutive bacteriological samples shall demonstrate an exceedance of clause (A), (B), (C), or (D). Failure to collect and analyze water samples in accordance with subdivision (15) and this subdivision during the period that a pool is open for use is considered an unsatisfactory report for the applicable month.

(17) When the pool or spa must be closed due to an unsatisfactory sample report, an additional water sample must be submitted to an approved laboratory. The pool or spa may be reopened upon receipt of a satisfactory report.

(18) All items in the room used to store pool or spa water treatment chemicals shall be stored at least six (6) inches above the floor to allow for flushing the area in the case of a spill.

(19) All pool or spa water treatment chemicals shall be stored in accordance with the manufacturer's recommendations.

(20) A twenty-four (24) unit first aid kit that meets American National Standards Institute (ANSI) standard Z308.1-2003 or 2009, shall be provided at each tourist home having a pool or spa.

(21) Prior to occupancy of a tourist home containing a spa, a legible printed warning shall be provided to the lodger stating the following:

(A) Pregnant women, small children, or persons with heart disease, diabetes, high blood pressure, or low blood pressure should not enter the spa except under advice of a physician.

(B) Avoid use while under the influence of alcohol, tranquilizers, or other drugs that cause drowsiness or raise or lower blood pressure.

(C) Exposure greater than fifteen (15) minutes may result in drowsiness, nausea, or fainting.

  (c) The test kits used to determine quality of the water in a pool or spa at a tourist home shall have reagents replaced according to the manufacturer's requirements and shall meet the following:

(1) For pools or spas that use chlorine as a disinfectant, the test kit shall cover a minimum range from zero (0) ppm to five (5.0) ppm or higher. The test kit must be:

(A) in increments of five-tenths (0.5) ppm; and

(B) capable of measuring total chlorine.

(2) For pools or spas that use a disinfectant other than chlorine, the test kit shall have the range and accuracy proportionate to the range required for chlorine test kits.

(3) When a cyanurate is used as a chlorine stabilizer, the test kit shall be capable of measuring cyanuric acid concentrations.

(4) A pH test kit:

(A) accurate to the nearest two-tenths (0.2) pH unit; and

(B) covering a minimum range of seven (7.0) to eight (8.0) pH units;

shall be used.

(5) A test kit capable of measuring total alkalinity shall be used.
