(Amendment)

DAR File No.: 38089
Filed: 11/01/2013 10:59:22 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The purpose of this amendment is to clarify by rule that float tank sanitation requirements are not applicable to this rule, and to make a grammatical correction.

Summary of the rule or change:

New language is added and a reference to float tanks is deleted to clarify that these types of devices are not regulated under this rule. Also makes a grammatical change, modifying the word "in" to the word "is" in Subsection R392-302-3(3).

State statutory or constitutional authorization for this rule:

• Section 26-15-2

Anticipated cost or savings to:

the state budget:

There are no additional cost or savings to the state budget as rulemaking activities will be covered by existing budgets.

local governments:

There are no additional costs or savings. There is only one known facility that could meet the current definition and is now regulated as a hydrotherapy pool.

small businesses:

There will be some savings as facilities who will offer float tanks in the future would not be required to be permitted under state rule.

persons other than small businesses, businesses, or local governmental entities:

There are no known entities who operate float tanks in the state at this time.

Compliance costs for affected persons:

There are no anticipated increased costs or savings for individuals in this category as they now are not required to pay a permit fee currently, and would not be required due to the proposed change.

Comments by the department head on the fiscal impact the rule may have on businesses:

This will have no effect on business.

(a) All parts of the interactive water feature shall be designed, constructed, maintained, and operated so there are no slip, fall, or other safety hazards, and shall meet the standards of the construction code adopted by the Utah Legislature under Section 58-56-4. A copy of the construction code is available at the office of the local building inspector.

(c) Areas adjacent to the water feature collection zones shall be sloped away at a minimum of two percent from the interactive water feature to deck drains or other approved surface water disposal systems. A continuous deck at least 3 feet, 0.91 meters, wide as measured from the edge of the collection zones must extend completely around the interactive water feature.

(d) Water discharged from all interactive water feature fountain or spray features shall freely drain by gravity flow through a main drain fitting to a below grade sump or collection system which discharges to a collector tank.

(e) All interactive water feature foggers and misters that produce finely atomized mists shall be supplied directly from a potable water source and not from the underground reservoir.

(f) The interactive water feature shall have an automated oxidation reduction potential (ORP) and pH controller installed and in operation whenever the feature is open for use. The controller shall be capable of maintaining disinfection and pH levels within the requirements for special purpose pools listed in Table 6. In addition, an approved secondary disinfection system the meets the requirements of in R392-302-33 (4)(c) through (4)(f)(iii) shall be installed and in operation whenever the feature is open for use.

(i) The interactive water feature filter system shall be capable of filtering and treating the entire water volume of the water feature within 30 minutes.

(ii) The interactive water feature filter system shall draft from the collector tank and return filtered and treated water to the tank via a minimum of 4 equally spaced inlet fittings. Inlet spacing shall also meet the requirements of section R392-302-17.

(iii) The interactive water feature circulation system shall be on a separate loop and not directly interconnected with the interactive water feature pump.

(iv) The suction intake of the interactive water feature pump in the underground reservoir shall be located adjacent to the circulation return line and shall be located to maximize uniform circulation of the tank.

(v) An automated water level controller shall be provided for the interactive water feature, and the drinking water line that supplies the feature shall be protected from any back flow by an air gap.

(vi) The water velocity through the feature nozzles of the interactive water features shall meet manufacturer's specifications and shall not exceed 20 feet per second.

(vii) The minimum size of the interactive water feature sump or collector tank shall be equal to the volume of 3 minutes of the combined flow of all feature pumps and the filter pump. Access lids or doors shall be provided to the sump and collector tank. The lids or doors shall be sized to allow easy maintenance and shall provide security from unauthorized access. Stairs or a ladder shall be provided as needed to ensure safe entry into the tank for cleaning and inspection.

(viii) The suction intake from the interactive water feature circulation pump shall be located in the lowest portion of the underground reservoir.

(ix) A means of vacuuming and completely draining the interactive water feature tank shall be provided.

(j) An interactive water feature is exempt from:

(i) The wall requirement of section R392-302-10;

(ii) The ladder, recessed step, stair, and handrail requirements of section R392-302-12;

(iii) The fencing and access barrier requirements of section R392-302-14;

(iv) The outlet requirements of section R392-302-18;

(v) The overflow gutter and skimming device requirements of section R392-302-19;
