RULE ANALYSIS

Purpose of the rule or reason for the change:

The changes are proposed to control Cryptosporidiosis. They are made in response to a final epidemiology report regarding an outbreak of Cryptosporidiosis in August of 2007. The change to the drain cover requirement is made because large drain covers are not commercially available that meet the existing drain cover certification requirements.

Summary of the rule or change:

The following additions have been made: 1) a definition of a cleansing shower has been added; 2) a requirement for operators to follow The Centers for Disease Control Fecal Accident Response Recommendations; 3) a requirement prohibiting swimmers from swimming if they have diarrhea, or have had diarrhea within the last two weeks; 4) a requirement for young children and those who cannot control evacuative bodily functions to wear swim diapers or waterproof swimwear; 5) requirements pool operators must follow in response to the Department of Health issuance of Cryptosporidiosis "Watches" and "Warnings"; 6) modifications to the requirement for drain covers that are less than 24 inches by 24 inches to meet the cited ANSI/ASME standard rather than requiring a listing by a laboratory that has tested the drain cover using the ANSI/ASME standard; 7) a requirement to provide soap for patrons in the shower area, in addition to lavatories; and 8) the drain cover requirement is relaxed to allow large drain covers that meet the standard but that have not been independently certified to meet the standard.

State statutory or constitutional authorization for this rule:

Section 26-15-2

This rule or change incorporates by reference the following material:

Centers for Disease Control and Prevention: Notice to Readers--Responding to Fecal Accidents in Disinfected Swimming Venues. Morbidity Mortality Weekly Report, May 25, 2001, Volume 50, pages 416-417; Centers for Disease Control and Prevention: 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; American National Standards Institute, ANSI Z535.1-2002, American National Standards For Environmental and Facility Safety Signs, November 7, 2002; and NSF International Standard/American National Standard, NSF/ANSI 50 - 2007, Circulation system components and related materials for swimming pools, spas / hot tubs, April 3, 2007

Anticipated cost or savings to:

the state budget:

There will be costs to write and implement the proposed change in the rule but these costs will be covered by existing budgets.

local governments:

There will be increased costs to local governments who own and operate pools to follow these new requirements. There are 2,726 public pools in the state. There are approximately 270 government-owned pools, and the balance are privately owned. Soap and soap dispensers in shower areas: it is not known how many soap dispensers are already provided by government pool operators, therefore, an accurate estimate cannot be done for the additional cost. However, soap dispensers cost approximately $15 each. If each large government owned pool had to add eight dispensers, then the aggregate governmental cost would be $32,400, plus labor costs to install, and the ongoing cost of providing soap. Cost for required signage: each pool would need to add one sign. Assuming signs cost approximately $40 each, the aggregate cost would be $10,800. However, the costs of the signs can be highly variable. Cost to purchase additional pool chemicals if an outbreak occurs: this is a "soft" cost, dependent upon occurrence. This will be an additional cost, but because this factor is affected by a diverse number of variables (method followed, pool size, type of chemical, and duration), a cost that would be meaningful cannot be estimated. The change to the drain cover requirements may result in a cost-savings for some pools not yet constructed. However, the amount is highly dependent on the design of each individual pool.

small businesses and persons other than businesses:

There are approximately 2,456 privately owned pools in the state. The Department of Health does not track which of those pools are operated by small businesses with less than 50 employees, but estimates that most fall into that category. There will be increased costs to follow the new requirements. Soap and soap dispensers in shower areas: the number of soap dispensers already provided by private pool operators is not known, therefore, an accurate estimate of the additional cost cannot be done. However, soap dispensers cost approximately $15 each. If each pool had to add two dispensers, then the aggregate cost would be $73,680, plus labor costs to install, and the ongoing cost of providing soap. Cost for required signage: each pool would need to add one sign. Assuming signs cost approximately $40 each, the aggregate cost would be $98,240. However, the costs of the signs can be highly variable. Cost to purchase additional pool chemicals, if an outbreak occurs: this is a "soft" cost, dependent upon occurrence. This will be an additional cost, but because this factor is affected by a diverse number of variables (method followed, pool size, type of chemical, and duration), a cost that would be meaningful cannot be estimated. Swimming diapers for patrons: swimming diapers cost approximately $3 each. The total number of patrons of swimming pools requiring swim diapers is not known, therefore, cannot be estimated. The change to the drain cover requirements may result in a cost-savings for some pools not yet constructed. However, the amount is highly dependent on the design of each individual pool.

Compliance costs for affected persons:

There are approximately 2,726 pools in the state. There will be increased costs to follow the new requirements. Soap and soap dispensers in shower areas: the number of soap dispensers already provided by private pool operators is not known, therefore, an accurate estimate of the additional number/per individual that will be required cannot be done. However, soap dispensers cost approximately $15 each, plus installation and the ongoing cost of providing soap. Cost for required signage: each pool would need to add one sign. Signs cost approximately $40 each. Cost to purchase additional pool chemicals if an outbreak occurs: this is a "soft" cost, dependent upon occurrence. This will be an additional cost, but because this factor is affected by a diverse number of variables (method followed, pool size, type of chemical, and duration), a cost that would be meaningful cannot be estimated. Swim diapers: the cost would be $3 each.

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

The analysis of the costs listed above is correct. There will be a necessary fiscal impact on business. Public confidence in the safety of using public pools and stopping the spread of disease justifies those costs. David N. Sundwall, MD, Executive Director
