RULE ANALYSIS

Purpose of the rule or reason for the change:

This amendment updates the list of authorizing statutes, fixes typos, and introduces a definition and a new section in response to comments from the Administrative Rules Review Committee.

Summary of the rule or change:

Nonsubstantive changes update the list of authorizing statute to include Subsection 26-1-30(9) and Section 26-7-1; add the inches equivalent for signage requirements in the new Subsection R392-302-38(2)(b); add a footnote to Table 6 reflecting the current language in Subsection R392-302-27(1)(b)(i); and fixed the numbering in Section R392-302-21. The change also fixes a typo in the new Subsection R392-302-39(3)(c) to require rules lettering to be 0.5 inches tall instead of 1.5 inches, and adds a definition of "Instructional Pool". Substantial revision have been made to the Special Purpose Pool Section R392-302-31. This has been divided into separate sections (R392-302-32, R392-302-33, R392-302-34, and R392-302-35) for each type of special purpose pool. A new Section R392-302-36 is added for Instructional Pools. Changes have been made throughout the rule to reflect the new section numbers.

Statutory or constitutional authorization for this rule:

• Section 26-1-5
• Section 26-15-2
• Subsection 26-1-30(23)

Anticipated cost or savings to:

the state budget:

There are no anticipated costs or savings to the state budget resulting from this rule change.

local governments:

This rule change will affect new construction of a pool if it meets the requirements to be an instructional pool. This rule change does not require construction or operational changes to existing facilities. A local government building an instructional pool may have an approximate savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. The Department of Health (Department) is unable to estimate this benefit due to the wide range of possible costs involved (size, features, types of disinfectant, and plumbing, etc.). It is unlikely this rule change will have an ongoing cost or savings as the rule changes do not affect the operation of the pool.

small businesses:

There are an estimated 11 swim school or swim instruction businesses from NAICS 611620, 611710, and 812199. There are an estimated 61 small businesses affected by this rule from NAICS 541330, 561790, 541690, 425120, 238992, 238991, and 236220, but an inestimable number from NAICS 713990, 713940, 531311, and 721110 as these businesses may or may not have swimming pools, and there is no reasonable method of determining such. In FY17 there were 3,063 permitted facilities, but the data is not available to determine which of these are small or non-small businesses. This rule change will affect new construction of a pool if it meets the requirements to be an instructional pool. This rule change does not require construction or operational changes to existing facilities. A small business building an instructional pool may have an approximate savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. The Department is unable to estimate this benefit due to the wide range of possible costs involved (size, features, types of disinfectant, and plumbing, etc.). It is unlikely this rule change will have an ongoing cost or savings as the rule changes do not affect the operation of the pool.

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

There are an estimated 41 non-small businesses from NAICS 713990, 713110, 713940, but an inestimable number of large businesses with pool facilities from NAICS 531311 and 721110. In FY17 there were 3,063 permitted facilities, but the data is not available to determine which of these are small or non-small businesses. This rule change will affect new construction of a pool if it meets the requirements to be an instructional pool. This rule change does not require construction or operational changes to existing facilities. A non-small business building an instructional pool may have an approximate savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. The Department is unable to estimate this benefit due to the wide range of possible costs involved (size, features, types of disinfectant and plumbing, etc.). It is unlikely this rule change will have an ongoing cost or savings as the rule changes do not affect the operation of the pool.

Compliance costs for affected persons:

No one specific person will be affected by this rule change.

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

The proposed amendment is a response to comments made by the Legislature's Administrative Rules Review Committee in a recent hearing. The Special Purpose Pool section has been substantially revised. It was divided into separate sections for each type of a special purpose pool with the addition of a new section for Instructional Pools. There may be significant savings of 80% - 90% to a small business building an instructional pool but the Department is unable to estimate the benefit due to the wide range of possible costs involved (size, features, types of disinfectant, and plumbing, etc.).

Appendix 2: Regulatory Impact to Non-Small Businesses

There are an estimated 41 non-small businesses from NAICS 713990, 713110, 713940, but an inestimable number of large businesses with pool facilities from NAICS 531311 and 721110. In FY17 there were permitted 3063 facilities, but the data is not available to determine which of these are small or non-small businesses.

 

This rule change will affect new construction of a pool if it meets the requirements to be an instructional pool. This rule change does not require construction or operational changes to existing facilities.

 

A non-small business building an instructional pool may have a savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. The Department is unable to estimate this benefit due to the wide range of possible costs involved (size, features, types of disinfectant and plumbing, etc.). It is unlikely this rule change will have an ongoing cost or savings as the rule changes do not affect the operation of the pool.

 

The head of Department of Health, Dr. Joseph Miner, has reviewed and approved this fiscal analysis.

The sign shall be at least 17 inches, 43 centimeters, wide by 11 inches, 28 centimeters, high.

(a) Centered immediately below the blue panel shall appear the words "CRYPTO DISEASE PREVENTION" in capital letters.

(b) The body of the notice sign shall be in upper case letters at least 0.39 inches, 1.0 centimeters, high and include the following four bulleted statements in black letters:

-All with diarrhea in the past 2 weeks shall not use the pool.

-All users must shower with soap to remove all fecal material prior to pool entry and after using the toilet or a diaper change.

-All less than 3 yrs or who wear diapers must wear a swim diaper and waterproof swimwear. Diapers may only be changed in restrooms or changing stations.

-Keep pool water out of your mouth.

(3) If a cryptosporidium warning has been issued, each operator of a public pool subject to the warning shall, at a minimum, implement the following cryptosporidium counter measures:

(a) maintain the disinfectant concentration within the range between two mg/l (four mg/l for bromine) and the concentration listed on the product's Environmental Protection Agency mandated label as the maximum reentry concentration, but in no case more than five mg/l (10 mg/l for bromine);

(b) maintain the pH between 7.2 and 7.5; and

(c) maintain the cyanuric acid level that meets the requirement of R392-302-27(3), except the maximum level shall be reduced to 30 mg/l.

(4)(a) If a cryptosporidium warning has been issued, in addition to the requirements listed in R392-302-[33]38 (3), the owner or operator of a public pool shall implement any additional cryptosporidium countermeasures listed in subsection below sufficient to achieve at least a 99.9 percent destruction or removal of cryptosporidium oocysts twice weekly, except as provided in R392-302-[33]38 (4)(b).

(b) Hyperchlorination using sodium hypochlorite or calcium hypochlorite to achieve a concentration multiplied by time (CT) value of 15,300 mg/l minutes. Table 7 lists examples of chlorine concentrations and time periods that may be used to achieve the required CT value. The operator shall not allow anyone to use the pool if the chlorine concentration exceeds the Environmental Protection Agency maximum reentry concentration listed on the product's label, but in no case if the concentration exceeds five mg/l. The operator of any public pool not required to have a lifeguard by R392-302-30 (2) shall hyperchlorinate at least once weekly.

(c) A full flow ultraviolet treatment system that meets the requirements of standard NSF/ANSI 50-2015 for ultraviolet light process equipment. The owner or operator shall ensure that the system is installed and operated according to the manufacturer's recommendations. The owner or operator shall obtain from the manufacturer of the system documentation of third-party challenge testing that the system can achieve a single pass 99.9 percent inactivation of cryptosporidium or the bacteriophage MS2 at the pool design flow rate and during normal operating conditions. The owner or operator shall maintain and make available for inspection the manufacturer's documentation.

(d) An ozone treatment system that achieves a CT value of 7.4 and a flow-through rate at least four times the volume of the pool every three and a half days. The system shall meet the requirements of standard NSF/ANSI 50-2015 for ozone process equipment. The owner or operator shall ensure that the system is installed and operated according to the manufacturer's recommendations.

(e) A cryptosporidium oocyst-targeted filter system installed and operated according to the manufacturer's recommendations. The filter shall meet the requirements of R392-302-20. The owner or operator shall obtain from the manufacturer of the system documentation of third-party challenge testing that the system can achieve a single pass 99 percent reduction of particles in the range of 4 to 6 microns or cryptosporidium oocysts at the pool design flow rate and normal operating conditions. The owner or operator shall maintain and make available for inspection the manufacturer's documentation.

(f) A system approved by the local health officer. The health officer's approval of a system for use as an alternative shall be based on the system's documented ability to:

(i) achieve cryptosporidium removal or inactivation to a level at least equivalent to the requirements in R392-302-[33]38 (4)(a);

(ii) assure safety for swimmers and pool operators; and

(iii) comply with all other applicable rules and federal regulations.

(5) If the Executive Director or local health officer issues a restriction on the use of public pools by certain persons as part of the cryptosporidium warning the operator shall restrict persons within that segment of the population from using the facility.

(6) If the Executive Director or local health officer determines that a pool is a cryptosporidiosis threat to public health, he may order the pool to close. The owner or operator of the pool may not reopen until the person issuing the order has rescinded it.

 

R392-302-[34]39. Signs.

(1) Signs required in R392-302 shall be placed to alert and inform patrons in enough time that the patrons may take appropriate actions.

(2) Signs shall be written in a lettering style, stroke width, spacing, and contrast with the background such that the sign is clearly visible.

(3) As required in different subsections of this rule, sign lettering shall meet one or more, if stated, of the following minimum size standards:

(a) "4 Inch Safety Sign" shall be written in all capital letters that are at least four inches, 10.2 centimeters in height.

(b) "2 Inch Safety Sign" shall be written in all capital letters that are at least two inches, 5.1 centimeters, in height.

(c) "Rule Signs" shall be written with any required signal word, warning or caution, as the sign heading in letters at least two inches, 5.1 centimeters, in height and the body or bulleted rules in letters at least [1.5]0.5 inches, [3.8]1.27 centimeters, in height.

(i) If the sign can only be viewed from more than a distance of ten feet, 3.048 meters, the letter height shall be larger in the same proportion as the required viewing distance is to ten feet, 3.048 meters.

(ii) The Local Health Officer may approve smaller letter sizes than those required in R392-302-[34]39(3)(c) if the sign will always be viewed from less than a ten foot, 3.048 meters, distance and if the Local Health Officer agrees that the sign meets the requirements of R392-302-[34]39(1) and (2).
