37.115.1313   SATURATION INDEX
(1) The following equation and ARM 37.115.1314, Table 7 shall be used to calculate the saturation index: the saturation index equals pH plus temperature factor (TF) plus calcium factor (CF), plus alkalinity factor (AF) minus 12.1. (SI=(pH + TF + CF + AF) - 12.1.)

(3) Saturation index values shall be calculated weekly. Perfectly balanced water has a saturation index value of 0.0. A saturation index value below -0.5 shows corrosive water and a saturation index value higher than +0.5 shows scale forming water.

(4) The saturation index value should be maintained between -.5 and +.5. Ideal values are -.2 to +.2 on the saturation index.

(5) If the reading falls outside the range of -.5 and +.5 the licenseholder/operator shall initiate the saturation index adjustments to the pool water within 24 hours.

37.115.1315   WATER CLARITY
(1) Acceptable water clarity of a pool, spa, or other water feature shall be maintained at all times. It shall be determined by one of the following methods:

(a) when standing anywhere on the perimeter or deck of the pool, spa, or other water feature, the grates on the main drain(s) at the deepest portion of the pool floor must be clearly visible and sharply defined at all times; or

(b) water must, at all times, have sufficient clarity so that a black disc, six inches in diameter, and placed on a white background in the deepest point of the pool, spa, or other water feature, must be clearly visible and sharply defined when viewed from any point on the deck within five feet of any pool edge.

(2) When the licenseholder or operator disputes the department's determination that a pool, spa, or other water feature does not meet clarity requirement as defined in (1), the department may use an NTU reading to make its final determination. A pool will be determined to have sufficient clarity only where the NTU reading is 1.0 NTU or less.

(3) Clarity readings shall be marked daily on the log sheets for the facility. Clarity readings are defined by the following terms:

(a) "excellent" means that the water is sparkling clear or it has an NTU reading <.5;

(b) "good" means that the water is clear to very clear or it has an NTU reading of 0.5-1.0; and

(c) "poor" means the water clarity is significantly deteriorated so that the main drain cannot be seen clearly or the bottom of the pool is obscured, or the water has an NTU reading in excess of 1.0.

37.115.2207   HEARING, ORDER OF PRESENTATION, BURDENS OF PROOF
(1) In a hearing concerning adverse action or proposed adverse action against an existing license, the department shall present its case-in-chief first during the hearing to establish the background facts and the basis for the action or proposed action. The department shall have the burden to establish by a preponderance of the evidence that there is a reasonable basis for the department to take the adverse action. The licensee shall then have the opportunity to present its case-in-chief. The licensee has the burden of persuasion to establish that there is not a reasonable basis for the adverse action or proposed adverse action against the existing license. The department shall have the opportunity to present rebuttal evidence.

(2) In a hearing concerning the denial or proposed denial of a license, the department shall open the hearing by providing evidence to establish the background facts and any reasons relied upon by the department for the denial of the license or the proposed denial of the license. The license applicant or operator shall then present its case-in-chief. The license applicant has the burden of proof to establish by a preponderance of the evidence that the denial of the license has no reasonable basis and that all requirements of Title 50, chapter 53, MCA, and ARM Title 37, chapter 115, subchapters 1 through 22 have been met and the license applicant is therefore entitled to the license. The department shall then have an opportunity to present its case-in-chief. The department has the burden of persuasion to show that there is some reasonable basis for denial of the license or that the license applicant has not met all requirements of Title 50, chapter 53, MCA, and ARM Title 37, chapter 115, subchapters 1 through 22. The license applicant or operator shall have the opportunity to present rebuttal evidence.

(3) If the department has established by a preponderance of the evidence that there have been violations of Title 50, chapter 53, MCA, or ARM Title 37, chapter 115, subchapters 1 through 22, the department's exercise of discretion in deciding the level of negative licensing action to take must be upheld unless the hearing examiner finds that in light of all the circumstances, the penalty the department has imposed or proposed to impose is so disproportionate or excessive as to be arbitrary and capricious.

37.115.2209   LIMITS ON CONSIDERATION OF PRIOR VIOLATIONS

(1) Except as provided in (2) through (4), the hearing examiner may not consider any prior violations that were included on a notice of violation delivered to the licensee, license applicant, or operator of a swimming pool, spa, or other water feature if:

(a) satisfactory corrective action was taken and accepted by the department; or

(b) the licensee, license applicant, or operator requested a fair hearing to challenge the notice of violation, the hearing examiner issued a dispositive order that denied all of the department's claims against the licensee and that order was not appealed or it was upheld after any appeal.

(2) The hearing examiner may consider any history of corrective action that was taken in response to a notice of violation and that was accepted by the department only for the limited purpose of determining whether:

(a) the history of past violations taken together with the current violations supports a penalty as severe as the level of adverse action imposed by or requested by the department; or

(b) the department's imposition of the penalty or proposed penalty is so severe as to be arbitrary and capricious.

(3) In considering any prior violations by the licensee for purposes of (2), any prior violation cited at the pool, spa, or other water feature is presumed admitted unless it was timely contested.

(4) In considering any such prior violations, the hearing examiner shall weigh the frequency and the seriousness of the prior violations and the willingness and ability the licensee has demonstrated in the past to take corrective action that prevented reoccurrence of violations.
